I. Introduction

In Philippine civil law, fraud is called dolo. It refers to deception, trickery, or insidious words or machinations used by one party to influence another in relation to a contract. Fraud may affect consent, liability, damages, and the validity or enforceability of contractual obligations.

Two important civil law concepts are dolo causante and dolo incidente.

They are often confused, but they have different legal effects:

Dolo causante is fraud that causes a party to enter into a contract. Without it, the party would not have consented. It makes the contract voidable.

Dolo incidente is fraud that does not cause the party to enter into the contract, but affects the terms, conditions, price, or manner of performance. The party would still have contracted, but on better or different terms. It does not make the contract voidable; it gives rise to damages.

The distinction is crucial. If fraud is causante, the remedy may be annulment of the contract. If fraud is incidente, the remedy is usually damages while the contract remains valid.

II. Meaning of Dolo in Civil Law

Dolo, in civil law, is fraud employed in the formation or performance of an obligation. It may consist of deliberate concealment, false statements, manipulation, misleading conduct, or other deceptive acts.

Fraud may appear in several stages:

before the contract is signed;
during negotiation;
at the moment of consent;
after the contract has been perfected;
during performance;
during enforcement or collection.

Civil law treats fraud differently depending on its role. Fraud may vitiate consent, give rise to damages, constitute breach of contract, or amount to a criminal offense in separate cases.

III. Legal Basis in the Civil Code

Under Philippine civil law, consent is one of the essential requisites of a valid contract. Consent must be freely and intelligently given. When consent is obtained through mistake, violence, intimidation, undue influence, or fraud, the contract may be voidable.

The Civil Code recognizes fraud as a vice of consent when, through insidious words or machinations by one contracting party, the other is induced to enter into a contract which, without them, the latter would not have agreed to.

The Civil Code also recognizes that incidental fraud obliges the person employing it to pay damages.

This is the statutory foundation for the distinction between dolo causante and dolo incidente.

IV. Dolo Causante: Definition

Dolo causante, also called causal fraud, is fraud that is the determining cause of a party’s consent.

It exists when one party uses deception so serious that the other party would not have entered into the contract at all without the fraud.

In simple terms:

The fraud caused the contract.

The deceived party’s consent was not merely affected; it was obtained because of the fraud. The fraud went to the very reason for entering into the agreement.

V. Dolo Incidente: Definition

Dolo incidente, also called incidental fraud, is fraud that affects only the incidentals of the contract.

It exists when a party would still have entered into the contract even without the fraud, but would have agreed to different or more favorable terms.

In simple terms:

The fraud did not cause the contract, but caused loss or disadvantage in the contract.

The contract remains valid, but the guilty party may be liable for damages.

VI. Basic Distinction

Point of Comparison	Dolo Causante	Dolo Incidente
Effect on consent	Vitiates consent	Does not vitiate consent
Role of fraud	Determines the decision to contract	Affects only terms or incidents
Would the party have contracted without fraud?	No	Yes, but on different terms
Effect on contract	Voidable	Valid and binding
Main remedy	Annulment, plus damages when proper	Damages
Seriousness	Substantial and decisive	Incidental or secondary
Legal theory	Vice of consent	Civil liability for damages
Example	Buyer buys land because seller falsely claims ownership	Buyer still wants land but pays higher price because seller lies about minor features

VII. Importance of the Distinction

The distinction matters because the remedies are different.

If the fraud is dolo causante, the innocent party may seek annulment of the contract. Annulment means the contract is set aside because consent was defective.

If the fraud is dolo incidente, the innocent party cannot annul the contract merely because of the incidental deception. The contract remains effective, but the injured party may recover damages.

Misclassifying fraud may lead to the wrong lawsuit, wrong evidence, wrong prayer for relief, and possible dismissal.

VIII. Dolo Causante as a Vice of Consent

Consent is essential to a valid contract. But consent must be real. If a party signs only because they were deceived on a matter that determined their consent, the law treats the consent as defective.

Dolo causante is therefore one of the classic vices of consent.

A contract affected by dolo causante is not void from the beginning. It is voidable. This means it is valid and binding until annulled by a proper court action or until ratified by the party entitled to annul.

IX. Dolo Incidente as Source of Damages

Dolo incidente does not destroy consent. The party still intended to contract. The fraud merely caused them to accept less favorable terms, pay more, receive less, assume additional burden, or suffer loss in the manner of performance.

Because consent remains sufficient, annulment is not the proper remedy. The law instead imposes liability for damages.

The guilty party must indemnify the injured party for loss caused by the incidental fraud.

X. Essential Requisites of Dolo Causante

For fraud to be considered dolo causante, the following elements are usually important:

there was fraud, deceit, machination, concealment, or misrepresentation;
the fraud was serious and substantial;
the fraud was employed by one contracting party or with that party’s knowledge;
the fraud induced the other party to enter into the contract;
without the fraud, the deceived party would not have entered into the contract;
the deceived party was not guilty of negligence so gross as to defeat the claim;
the fraud is proven by clear and convincing evidence or at least sufficient competent proof under civil standards;
the action is filed within the proper prescriptive period.

The most important point is causation: the fraud must be the reason why consent was given.

XI. Essential Requisites of Dolo Incidente

For dolo incidente, the following are usually present:

there was fraud or deceit;
the fraud was not the determining cause of the contract;
the injured party would still have entered into the contract;
the fraud affected the price, terms, performance, quality, quantity, timing, or other incident;
the injured party suffered damage;
the damage was caused by the fraud;
the fraud is proven by competent evidence.

The central idea is that the contract would still exist, but the injured party was harmed by deception in its details.

XII. Serious Fraud Versus Incidental Fraud

Not every false statement gives rise to annulment. To annul a contract, the fraud must be serious.

Serious fraud is deception that directly affects the principal reason for contracting.

Examples of serious fraud:

pretending to own property being sold;
concealing that land is already sold to another;
selling a fake title as genuine;
falsely representing that a business has a government permit essential to operations;
concealing that a vehicle was stolen;
inducing investment by fabricating the existence of a business;
selling a condominium unit that does not legally exist;
misrepresenting identity in a personal contract where identity is essential;
hiding a legal defect that makes the contract useless for the buyer’s purpose.

Incidental fraud affects lesser aspects.

Examples of incidental fraud:

exaggerating expected income from a business, but buyer would still buy;
misstating minor repairs needed for a vehicle;
overstating foot traffic in a commercial lease;
misrepresenting exact inventory count by a small margin;
hiding a minor defect that affects price but not the decision to buy;
misrepresenting delivery convenience but not the object itself;
giving inaccurate but non-essential information that caused additional expense.

The classification depends on facts.

XIII. Examples of Dolo Causante

Example 1: Fake Land Ownership

A seller shows a buyer a fake title and claims to own a parcel of land. The buyer buys only because they believe the seller owns the property. Later, the buyer discovers that the seller never owned it.

This is likely dolo causante because the buyer would not have bought the land if the truth were known.

Example 2: False Authority to Sell

A person claims to be authorized by the registered owner to sell land. They show a fake special power of attorney. The buyer signs the contract because of that supposed authority.

The fraud goes to the power to sell. It may be dolo causante.

Example 3: Non-Existent Business Investment

A person invites another to invest in a corporation, showing fake financial statements, fake customers, and fake permits. The investor invests only because of those documents.

The fraud caused the investment contract.

Example 4: Concealed Legal Prohibition

A seller sells property while concealing that the property cannot be transferred due to a legal restriction known to the seller and material to the buyer’s purpose.

If the buyer would not have bought had they known, the fraud may be causante.

Example 5: Sale of Counterfeit Goods as Genuine

A seller represents counterfeit luxury goods, equipment, or branded merchandise as genuine. The buyer buys because authenticity is the principal reason.

This may be dolo causante.

XIV. Examples of Dolo Incidente

Example 1: Overstated Vehicle Condition

A buyer already wants a second-hand car and would have bought it, but the seller lies about minor repair history, causing the buyer to pay a higher price.

The fraud may be incidental if the buyer would still have bought the car at a lower price.

Example 2: Minor Area Discrepancy

A buyer purchases land primarily because of location. The seller exaggerates the usable area slightly, but the buyer would still have purchased if the true area were known.

The remedy may be damages or price adjustment, depending on facts.

Example 3: Misstated Delivery Time

A supplier falsely says goods will arrive in one week, though they know it will take three weeks. The buyer would still have ordered but suffers losses due to delay.

This may be incidental fraud or breach, giving rise to damages.

Example 4: Inflated Earnings Projection

A seller of a small business exaggerates projected future earnings. The buyer had independent reasons to buy and would still have purchased, but at a lower price.

This may be dolo incidente if the exaggeration affected price but not consent itself.

Example 5: Concealed Minor Defect

A seller conceals a minor defect that does not defeat the buyer’s principal purpose. The buyer would still buy but would negotiate a discount.

The remedy is damages, not annulment.

XV. Dolo Causante Makes the Contract Voidable

A contract affected by dolo causante is voidable because the consent of one party was vitiated.

A voidable contract:

is valid until annulled;
produces legal effects before annulment;
may be ratified;
may be annulled by the party whose consent was vitiated;
cannot generally be attacked by strangers;
may require mutual restitution after annulment;
may give rise to damages if damage was suffered.

The court does not automatically treat the contract as nonexistent. A proper action for annulment is normally required.

XVI. Dolo Incidente Does Not Void the Contract

A contract affected only by dolo incidente remains valid.

The injured party may sue for damages but must generally continue to respect the contract, unless other grounds for rescission, resolution, breach, or annulment exist.

Dolo incidente does not remove consent. It merely creates liability for injury caused by the fraudulent act.

XVII. Remedies for Dolo Causante

The principal remedies may include:

annulment of contract;
restitution of what was given;
cancellation of related documents;
reconveyance, if property was transferred;
return of purchase price;
damages;
interest;
attorney’s fees, if justified;
injunction, if needed;
cancellation of title or annotation, if real property is involved.

The remedy depends on the nature of the contract and the relief needed to restore the parties.

XVIII. Remedies for Dolo Incidente

The principal remedy is damages.

Damages may include:

actual damages;
price difference;
repair cost;
lost profits, if proven;
expenses caused by fraud;
interest;
attorney’s fees in proper cases;
moral damages in exceptional cases if allowed by law and facts;
exemplary damages if the fraud is wanton, fraudulent, oppressive, or malevolent.

The contract generally remains effective.

XIX. Annulment and Restitution

If a contract is annulled due to dolo causante, the parties are usually restored to their original positions as far as possible.

This may require:

return of money paid;
return of property received;
cancellation of deed;
cancellation of title, if proper;
accounting for fruits or income;
return of documents;
reimbursement of necessary expenses;
interest or damages.

If restitution is impossible because the property was sold to an innocent third person, other remedies may be needed.

XX. Ratification of a Voidable Contract

A contract affected by dolo causante may be ratified.

Ratification may be express or implied.

A. Express Ratification

The deceived party, after learning of the fraud, expressly confirms the contract.

B. Implied Ratification

The deceived party, with knowledge of the fraud and after the cause of voidability has ceased, performs acts showing intention to abide by the contract.

Examples:

continuing to accept benefits after discovering fraud;
continuing payments after full knowledge;
selling the property acquired under the contract;
executing documents confirming the transaction;
failing to act while treating the contract as valid.

Ratification extinguishes the action to annul. Once ratified, the contract can no longer be annulled on the ground of fraud, although damages may still be examined depending on circumstances.

XXI. Prescription of Action for Annulment

An action for annulment based on fraud must be filed within the period provided by law. In civil law, the period for annulment of voidable contracts based on fraud generally begins from the time of discovery of the fraud.

Delay can be fatal.

A party who discovers fraud should promptly:

preserve evidence;
send written notice or demand;
stop acts implying ratification;
consult counsel;
file the proper case within the prescriptive period.

Waiting too long may result in prescription, laches, or implied ratification.

XXII. Burden of Proof

The party alleging fraud has the burden of proof.

Fraud is never presumed. It must be proven by evidence.

Evidence may include:

false documents;
messages;
emails;
advertisements;
witnesses;
receipts;
contracts;
expert reports;
financial statements;
title records;
admissions;
proof of concealment;
inconsistent statements;
bank records;
notarized documents;
government certifications.

Courts are cautious in annulling contracts because contracts are presumed valid.

XXIII. Fraud Must Be Proved Clearly

A party cannot simply say, “I was deceived.” The facts must show what was said, who said it, when it was said, why it was false, how it induced consent, and how the injured party relied on it.

A strong fraud allegation should answer:

What exactly was misrepresented?
Who made the misrepresentation?
Was it false when made?
Did the person know it was false?
Did the deceived party rely on it?
Would the deceived party have refused to contract if the truth were known?
What damage resulted?
When was the fraud discovered?
Did the deceived party ratify the contract after discovery?

XXIV. Fraud by One Party, Not by Third Person

For fraud to vitiate consent, it must generally be employed by one contracting party against the other, or at least be known to or participated in by the benefited contracting party.

If fraud is committed by a third person without the knowledge or participation of the contracting party, it may not always annul the contract, unless it created substantial mistake and the circumstances justify relief.

Example:

If a broker lies to a buyer without the seller’s knowledge, the buyer may have a claim against the broker, but annulment against the innocent seller may be harder unless the seller benefited from, authorized, ratified, or knew of the fraud.

XXV. Concealment as Fraud

Fraud is not limited to active lies. It may also consist of concealment when there is a duty to disclose.

Concealment may be fraudulent where:

one party deliberately hides a material fact;
the fact is known only to that party;
the other party cannot reasonably discover it;
the hidden fact is essential to consent;
the hiding party has a duty to speak;
silence misleads the other party.

Examples:

hiding that land is subject to a pending cancellation case;
hiding that a vehicle was previously declared a total loss;
hiding that equipment is stolen;
hiding that a business permit was revoked;
hiding a major structural defect known to the seller;
hiding that shares being sold are already pledged.

If concealment caused the contract, it may be dolo causante. If it only affected price or terms, it may be dolo incidente.

XXVI. Silence and Fraud

Mere silence is not always fraud. Parties are generally expected to protect their own interests. However, silence becomes fraudulent when the silent party had a duty to disclose and intentionally remained silent to mislead the other.

A duty to disclose may arise from:

law;
contract;
fiduciary relationship;
confidential relationship;
superior knowledge of hidden defects;
partial disclosure that becomes misleading;
special circumstances requiring good faith;
questions directly asked by the other party;
active concealment of facts.

XXVII. Exaggeration, Sales Talk, and Dolo

Not all exaggerations are actionable fraud.

Mere puffing or sales talk may include statements like:

“This is the best deal in town.”
“This business has great potential.”
“You will love this property.”
“This car is very reliable.”
“This investment is promising.”

These statements may be opinion, optimism, or marketing.

Fraud is more likely where the statement is a specific false representation of fact, such as:

“The title is clean,” when it is mortgaged;
“The business earned ₱5 million last year,” when records are fabricated;
“The car was never flooded,” when the seller knows it was;
“The property has a valid building permit,” when none exists;
“The machine is brand new,” when it is used and repaired.

XXVIII. Fraud and Negligence of the Deceived Party

A party alleging fraud must show reliance. But if the truth was easily discoverable and the party ignored obvious warnings, the court may examine whether reliance was reasonable.

However, fraudsters cannot always escape liability by saying the victim should have investigated. The effect of negligence depends on facts.

Important questions:

Was the fact hidden or discoverable?
Did the deceiving party actively prevent verification?
Was there a fiduciary relationship?
Was the victim inexperienced?
Were documents falsified?
Were there red flags ignored?
Was the victim given a chance to inspect?
Did the victim rely on official-looking records?
Was the fraud sophisticated?

Gross negligence may weaken a fraud claim, but deliberate fraud remains serious.

XXIX. Dolo Causante and Mistake

Fraud and mistake are related but different.

Mistake means a party consented because of an erroneous belief.

Fraud means the erroneous belief was caused by another party’s deceit.

Example:

If a buyer mistakenly believes a lot is 500 square meters because they misread the title, that may be mistake.

If the seller altered documents to make the buyer believe the lot is 500 square meters, that is fraud.

Fraud may create mistake, but fraud emphasizes the deceptive act of the other party.

XXX. Dolo Causante and Estafa

Civil fraud and criminal fraud are different.

Dolo causante may also amount to estafa in some cases, but not every civil fraud is criminal estafa.

A civil action focuses on:

annulment;
restitution;
damages.

A criminal case focuses on:

guilt beyond reasonable doubt;
deceit;
damage;
penalty;
civil liability arising from crime.

The same facts may support both civil and criminal remedies, but the standards, procedures, and consequences differ.

XXXI. Dolo in Contracts Versus Dolo in Crimes

The word “dolo” is also used in criminal law to mean criminal intent or malice. This is different from civil law fraud in contracts.

In civil law contracts, dolo refers to deceit affecting consent or causing damage.

In criminal law, dolo refers to intentional felony as opposed to culpa or negligence.

Do not confuse:

dolo causante and dolo incidente in civil contracts; with
dolo as criminal intent in felonies.

XXXII. Dolo Causante and Bad Faith

Fraud usually involves bad faith, but bad faith may exist even without dolo causante.

Bad faith may occur in performance of a contract, such as deliberately refusing to deliver, evading obligations, or abusing rights.

Dolo causante concerns fraudulent inducement before or at the time of contracting.

Bad faith during performance may support damages, rescission, resolution, or other remedies, but it is not always a vice of consent.

XXXIII. Dolo Causante and Breach of Contract

Fraud in inducement is different from breach of contract.

Fraud in inducement

The party was deceived into entering the contract.

Breach of contract

The party entered a valid contract but the other party failed to perform.

Example:

If a seller never intended to deliver and used fake documents to induce payment, there may be fraud.

If a seller intended to deliver but later failed due to financial difficulty, it may be breach.

The distinction affects remedies and proof.

XXXIV. Dolo Incidente and Breach

Dolo incidente may overlap with breach of contract.

Example:

A contractor promises to use a specific grade of material, secretly uses lower-grade material, and the owner would still have contracted but expected proper materials.

This may be:

incidental fraud;
breach of contract;
bad faith performance;
basis for damages;
possible rescission or resolution if breach is substantial.

The classification depends on whether the deception occurred before consent or during performance, and how material it was.

XXXV. Fraud Must Be Prior or Simultaneous for Dolo Causante

Dolo causante usually refers to fraud prior to or simultaneous with the giving of consent. It induces the contract.

Fraud committed after the contract is already perfected generally does not vitiate consent because consent was already given. It may instead constitute breach, bad faith, or fraud in performance.

Example:

If a seller lies before sale about ownership, that may be dolo causante.

If the seller truthfully owned the property at sale but later refuses to deliver title and lies about the reason, that may be breach or bad faith, not dolo causante.

XXXVI. Dolo Causante in Sale of Real Property

Real property transactions are common sources of fraud.

Dolo causante may exist where the seller:

uses a fake title;
conceals that the title is cancelled;
conceals prior sale;
falsely claims authority from owner;
hides a pending case affecting ownership;
conceals that property is under government restriction;
misrepresents location or identity of land;
sells land not owned by seller;
conceals major encumbrance;
misrepresents zoning where zoning is essential to buyer’s purpose.

If the buyer would not have bought had the truth been known, annulment may be proper.

XXXVII. Dolo Incidente in Sale of Real Property

Dolo incidente may exist where the buyer still wanted the property but was misled about secondary matters.

Examples:

seller exaggerates rental income;
seller understates minor association dues;
seller conceals small unpaid utility bills;
seller misstates minor repair costs;
seller exaggerates future development potential;
seller fails to disclose non-essential inconvenience.

The remedy may be damages or price adjustment, not annulment.

XXXVIII. Fraud in Land Titles

Fraud involving land titles is serious. However, civil law remedies depend on the role of fraud.

If a fake title induced the buyer to buy, it may be dolo causante.

If the title is genuine but the seller misrepresents minor title details that do not affect the buyer’s decision, it may be incidental.

If title has already been transferred through fraudulent registration, remedies may include annulment of deed, cancellation of title, reconveyance, damages, and criminal complaint.

XXXIX. Dolo Causante in Contracts of Loan

A loan contract may be affected by fraud.

Examples of dolo causante:

borrower fabricates collateral ownership;
borrower presents fake financial statements;
borrower lies about identity;
borrower uses fake authority for corporate borrowing;
lender induces borrower to sign loan documents by concealing usurious or illegal terms in a deceptive way;
borrower never intended to repay and used deceit to obtain funds.

If the deception caused the lender or borrower to enter the loan, annulment or other remedies may be considered.

XL. Dolo Incidente in Loans

Dolo incidente may occur where the party would still have entered the loan but on different terms.

Examples:

borrower slightly overstates income, causing a higher credit limit;
lender misstates minor fees but borrower would still borrow;
borrower misrepresents secondary collateral details;
lender hides processing charges that affect cost but not decision to borrow.

Damages, adjustment, or regulatory remedies may be more appropriate than annulment.

XLI. Dolo Causante in Employment-Related Contracts

Employment contracts may involve fraud, though labor laws also apply.

Examples:

employer recruits worker for a job that does not exist;
employer falsely promises a licensed position but has no authority;
worker falsifies professional license essential to hiring;
employee fabricates identity or qualifications essential to the position;
employer induces signing of quitclaim through false representation that no benefits are due.

If the fraud caused consent, the contract or waiver may be voidable or invalid under applicable principles.

XLII. Dolo Incidente in Employment-Related Contracts

Examples:

employer misstates minor benefits but employee would still accept job;
employee exaggerates experience but employer would still hire at lower salary;
employer misstates work schedule details affecting inconvenience but not hiring decision;
worker misrepresents secondary skill not essential to position.

The remedy may be damages, disciplinary action, reformation, or labor remedies, depending on facts.

XLIII. Dolo Causante in Waivers and Quitclaims

Fraud is important in quitclaims.

A quitclaim may be challenged if the employee was induced to sign by fraud, such as:

employer falsely says the employee has no legal claims;
employer conceals legally due amounts;
employer misrepresents the document as a mere receipt;
employer hides the waiver language;
employer tricks employee into signing under false explanation;
employee is told the document is only for clearance but it waives all claims.

If fraud caused the signing, the quitclaim may be invalid or voidable.

XLIV. Dolo Incidente in Settlement Agreements

If a party would still settle but was misled about incidental computation or timing, the fraud may be incidental.

Example:

An employer and employee agree to settle, but employer conceals a small component of computation. If the employee would still settle but for a higher amount, damages or correction may be proper.

If the concealed amount was central and the employee would not have settled at all, the fraud may be causante.

XLV. Dolo in Insurance Contracts

Insurance contracts require utmost good faith. Misrepresentation or concealment may have special effects under insurance law.

Fraud may involve:

concealment of material illness;
misstatement of age;
false claim history;
misrepresentation of insured property condition;
agent misrepresentation of coverage.

Depending on the materiality, fraud may lead to rescission, denial of claim, damages, or regulatory consequences.

Civil law concepts of fraud interact with special insurance rules.

XLVI. Dolo in Corporate Transactions

Fraud may arise in:

sale of shares;
investment agreements;
mergers;
subscription agreements;
shareholder buyouts;
joint ventures;
asset sales;
corporate loans.

Dolo causante may exist where financial statements, permits, liabilities, ownership, or corporate authority were falsified and induced the transaction.

Dolo incidente may exist where the buyer would still invest but at a different valuation if accurate information had been disclosed.

XLVII. Dolo in Family Property Agreements

Fraud may affect:

extrajudicial settlement;
waiver of inheritance;
partition;
sale among relatives;
donation;
family corporation transfers;
property settlement between spouses.

Examples of dolo causante:

heir is tricked into signing extrajudicial settlement by being told it is only an attendance sheet;
spouse signs property waiver after being falsely told property has no value;
heir waives inheritance based on concealed estate assets.

Family trust does not excuse fraud.

XLVIII. Dolo in Donations

A donation may be annulled or challenged if consent was obtained by fraud.

Examples:

donor is tricked into signing donation believing it is a loan document;
donee conceals material fact that induces donation;
elderly person is deceived about the nature of the document.

If the donor understood the donation but was deceived about incidental matters, damages or other remedies may apply depending on facts.

XLIX. Dolo in Leases

Fraud in lease contracts may be causante or incidental.

Dolo causante examples:

lessor falsely claims authority to lease property;
lessor conceals that the property is subject to demolition order;
lessor hides that premises cannot legally be used for the tenant’s stated business;
tenant uses fake identity essential to the lease.

Dolo incidente examples:

lessor exaggerates average foot traffic;
lessor understates minor repair needs;
tenant misstates expected number of staff;
lessor misstates minor utility cost.

L. Dolo in Construction Contracts

Construction disputes may involve fraud.

Dolo causante examples:

contractor uses fake license or credentials essential to contract;
contractor fabricates completed projects;
owner conceals that land cannot be built upon;
contractor induces payment through fake permits.

Dolo incidente examples:

contractor exaggerates minor capacity but can still perform;
supplier misstates delivery schedule;
party conceals small cost factors.

Fraud during performance may also become breach or bad faith.

LI. Dolo and Fiduciary Relationships

Fraud is more serious where trust and confidence exist.

Fiduciary or confidential relationships may include:

attorney-client;
agent-principal;
trustee-beneficiary;
corporate director-corporation;
guardian-ward;
broker-client in some contexts;
family member handling property;
business partner;
financial adviser-client.

In these relationships, concealment may more easily be treated as fraudulent because the fiduciary has a duty to disclose material facts.

LII. Dolo and Agency

If an agent uses fraud to induce a contract, liability may depend on authority, knowledge, benefit, and participation of the principal.

Important issues:

Did the principal authorize the agent?
Did the principal know of the fraud?
Did the principal benefit from the fraud?
Did the principal later ratify the transaction?
Was the agent acting within apparent authority?
Was the third party negligent?

The principal may be bound or liable in proper cases.

LIII. Dolo and Brokers

Brokers often make representations during sale, lease, or investment transactions. If a broker lies, the injured party should determine whether the broker acted:

independently;
as seller’s agent;
as buyer’s agent;
as dual agent;
with authority;
with the principal’s knowledge;
for personal commission.

The remedy may be against the broker, principal, or both depending on facts.

LIV. Dolo and Standard Form Contracts

Fraud may arise when one party uses complex documents to mislead the other.

Examples:

hiding waiver clauses;
misrepresenting a deed of sale as a loan document;
inserting terms different from what was explained;
using language the other party cannot understand while falsely explaining it;
rushing signature to prevent reading.

A person who signs a contract is generally bound by it, but fraud may overcome this presumption if proven.

LV. Failure to Read and Fraud

As a rule, a person who signs a document is presumed to know its contents. However, this rule may yield when fraud prevented understanding.

Examples:

document was switched;
signature page was attached to different terms;
signer was illiterate and document was falsely explained;
signer was blind or infirm and deceived;
contract was misrepresented as another document;
signer was prevented from reading by trickery;
language barrier was exploited.

The signer must prove the fraud.

LVI. Dolo and Language Barriers

Fraud may occur where a party exploits language difficulty.

Examples:

contract in English is falsely translated to Filipino;
foreign worker signs a document misrepresented by recruiter;
elderly person signs legal document they cannot read;
party is told a deed is only a receipt.

If the false explanation caused consent, dolo causante may exist.

LVII. Dolo and Vulnerable Parties

Courts may examine vulnerability in fraud cases, such as:

elderly persons;
persons with limited education;
persons with disability;
overseas workers;
consumers;
employees under pressure;
borrowers in financial distress;
family members relying on trust;
first-time buyers;
persons unfamiliar with legal documents.

Vulnerability does not automatically prove fraud, but it may affect the assessment of reliance and deception.

LVIII. Dolo Causante and Annulment of Deed of Sale

In property cases, a common remedy is annulment of deed of sale due to fraud.

The plaintiff may allege:

defendant misrepresented ownership or authority;
plaintiff signed because of fraud;
plaintiff would not have signed if truth were known;
deed should be annulled;
title or registration based on deed should be cancelled;
property or money should be returned;
damages should be awarded.

If the deed has already been registered, the plaintiff may need to include title cancellation and reconveyance remedies.

LIX. Dolo Incidente and Price Reduction

If fraud merely caused the buyer to pay too much, the remedy may be damages equivalent to the overpayment.

Example:

A buyer would still buy a machine, but seller falsely states it has 1,000 operating hours instead of 3,000. If the machine remains useful but worth less, damages may equal the price difference or repair cost.

The contract need not be annulled.

LX. Dolo and Reformation of Instruments

If the written contract does not reflect the true agreement because of fraud, mistake, inequitable conduct, or accident, reformation may be considered.

Reformation is different from annulment.

Annulment says the contract is defective and should be set aside.

Reformation says there was a valid agreement, but the written instrument does not express it correctly.

Fraud may support reformation if one party caused the document to reflect terms different from the true agreement.

LXI. Dolo and Rescission

Rescission is different from annulment.

Annulment addresses a defect in consent.

Rescission addresses economic injury or legally recognized grounds for undoing a valid contract.

Fraud may sometimes be pleaded with rescission, but the legal bases should be distinguished.

A party should be careful whether the remedy sought is:

annulment due to dolo causante;
damages due to dolo incidente;
rescission due to lesion or fraud of creditors;
resolution due to breach;
reformation due to incorrect written instrument;
cancellation or reconveyance due to title issues.

LXII. Dolo and Resolution for Breach

In reciprocal obligations, substantial breach may justify resolution or cancellation of the contract.

If deception occurred during performance rather than formation, the remedy may be resolution for breach, not annulment for dolo causante.

Example:

A contractor honestly enters the contract but later intentionally uses substandard materials. This may be breach in bad faith and may justify damages or resolution, depending on seriousness.

LXIII. Dolo and Quasi-Delict

Fraud is intentional, while quasi-delict generally involves fault or negligence. However, some factual situations may support alternative claims.

A plaintiff may plead alternative causes of action where allowed:

fraud in contract;
breach of contract;
culpa contractual;
quasi-delict;
unjust enrichment;
damages.

But the theories should not be confused.

LXIV. Dolo and Unjust Enrichment

If fraud causes one party to enrich themselves at another’s expense, unjust enrichment may be invoked in some cases, especially when contract remedies are inadequate.

However, where a specific contract governs and remedies are available, courts generally analyze the contract first.

LXV. Dolo and Consumer Transactions

Consumer sales may involve misrepresentation by sellers, dealers, online merchants, or service providers.

Dolo causante may exist where:

product is fake;
service does not exist;
seller hides a major defect;
buyer is induced by fabricated claims.

Dolo incidente may exist where:

features are exaggerated;
minor warranty terms are misrepresented;
delivery or accessories are misrepresented.

Consumer protection laws may provide additional remedies.

LXVI. Dolo in Online Transactions

Online fraud may involve:

fake sellers;
fake buyers;
fake payment confirmations;
fake courier receipts;
misrepresented products;
non-existent rentals;
fake investment platforms;
identity impersonation;
fake job offers;
fake titles or documents.

Civil law dolo may coexist with cybercrime or criminal fraud depending on facts.

Evidence preservation is crucial:

screenshots;
URLs;
messages;
payment receipts;
account names;
delivery records;
product photos;
advertisements.

LXVII. Dolo and Investment Scams

Investment scams often involve dolo causante.

Examples:

fake company;
fake SEC registration;
fake profits;
Ponzi scheme;
fabricated trading records;
fake collateral;
false guarantee;
forged contracts;
fake endorsements.

Investors typically would not have invested without the deception. Remedies may include annulment, restitution, damages, criminal complaint, and regulatory complaints.

LXVIII. Dolo and Misrepresentation of Law

Fraud usually involves false representation of fact. Misrepresentation of law may be treated differently because parties are presumed to know the law.

However, misrepresentation of law may become actionable where:

one party has superior legal knowledge;
there is fiduciary relation;
the legal statement implies false facts;
the statement is deliberately used to deceive;
the other party justifiably relied on it;
the representation concerns foreign law or technical regulatory status.

Example:

A person falsely claims that a property has all government approvals. This may be a factual misrepresentation about permits, not merely a legal opinion.

LXIX. Dolo and Future Promises

A broken promise is not automatically fraud. Fraud requires deceit at the time of contracting.

A future promise may be fraudulent if, when made, the promisor had no intention of performing and used the promise to induce consent.

Example:

A seller promises to deliver a title next month but genuinely expects to do so; later failure may be breach.

A seller promises to deliver title knowing they do not own the land and never can deliver; this may be fraud.

Proving fraudulent intent at the time of promise can be difficult but may be shown by circumstances.

LXX. Dolo and Opinions

Opinions generally do not constitute fraud unless made by an expert or fiduciary under circumstances where the other party reasonably relies on them as fact.

Example:

A seller saying “this business will probably grow” is opinion.

An accountant fabricating audited income statements is factual fraud.

A licensed engineer falsely certifying structural safety may create liability beyond mere opinion.

LXXI. Dolo and Expert Representations

When a person with expertise makes specific representations, courts may treat them more seriously.

Examples:

engineer certifies building safety;
doctor misrepresents medical status in a transaction;
accountant certifies false financial statements;
lawyer misrepresents title status;
broker misrepresents regulatory compliance;
appraiser fabricates valuation.

If expertise induced the contract, dolo causante may be found.

LXXII. Dolo and Due Diligence Clauses

Contracts often say the buyer inspected the property or conducted due diligence. Such clauses may weaken fraud claims but do not always defeat them.

A fraud claim may still succeed if:

seller actively concealed defects;
documents were falsified;
defects were not discoverable;
buyer was prevented from inspecting;
seller had exclusive knowledge;
clause itself was obtained by fraud;
fiduciary duty existed.

Due diligence clauses do not protect deliberate fraud absolutely.

LXXIII. Dolo and “As Is, Where Is” Clauses

An “as is, where is” clause means the buyer accepts the property in its existing condition. But it does not necessarily excuse intentional fraud.

If the seller hides a major defect or falsifies documents, the clause may not protect the seller.

However, if the defect was visible or discoverable and buyer accepted the risk, the fraud claim may be weaker.

LXXIV. Dolo and Waiver Clauses

A waiver clause may state that a party relied only on their own investigation. Such clauses may limit claims but cannot be used as a shield for deliberate fraud in all circumstances.

The court will examine:

clarity of waiver;
bargaining power;
sophistication of parties;
nature of fraud;
concealment;
public policy;
whether waiver itself was fraudulently obtained.

LXXV. Dolo and Notarized Contracts

A notarized contract is generally entitled to evidentiary weight. But notarization does not cure fraud.

A notarized deed may still be annulled if the signature, consent, authority, or transaction was fraudulently obtained.

However, the party attacking a notarized document must present strong evidence.

LXXVI. Dolo and Forgery

Forgery is different from fraud in consent.

If a signature is forged, there may be no consent at all. The contract may be void or inexistent as to the person whose signature was forged.

If the signature is genuine but obtained through deception, the contract may be voidable due to dolo causante.

Example:

Forged deed: owner never signed; no consent.
Fraudulently induced deed: owner signed but was deceived; voidable.

The remedy and proof differ.

LXXVII. Dolo and Simulation

Simulation occurs when parties make a contract appear to exist or appear different from the true agreement.

Fraud may be involved if one party uses simulation to deceive another.

Examples:

simulated sale to hide loan;
deed of sale used as security;
fake sale to defeat heirs or creditors;
nominee arrangement used to conceal ownership.

Dolo may be one element, but simulation has its own legal analysis.

LXXVIII. Dolo and Fraud of Creditors

Fraud of creditors is different from dolo causante.

Dolo causante deceives a contracting party into giving consent.

Fraud of creditors involves transactions designed to prejudice creditors, such as transferring property to avoid execution.

A creditor may seek rescission or other remedies, but the theory is different.

LXXIX. Dolo and Fraudulent Conveyance

Fraudulent conveyance may occur when a debtor transfers property to relatives or dummies to avoid creditors.

The creditor is not necessarily a party whose consent was vitiated. The remedy may involve rescission, accion pauliana, attachment, or execution remedies.

This is not usually dolo causante between contracting parties, though fraudulent intent exists.

LXXX. Dolo Causante and Public Documents

Public documents may be attacked for fraud, but the plaintiff must prove the fraudulent act.

Examples:

deed of sale notarized through impersonation;
forged special power of attorney;
false acknowledgment;
deed signed after misrepresentation;
falsified board resolution.

Civil remedies may be accompanied by criminal complaints.

LXXXI. Dolo and Corporate Authority

Fraud may involve false corporate authority.

Examples:

person claims to be authorized signatory but is not;
fake board resolution;
expired secretary’s certificate;
unauthorized sale of corporate asset;
person uses corporation name without authority.

If the other party entered the contract because of false authority, dolo causante or lack of authority may be involved.

LXXXII. Dolo and Minors or Incapacitated Persons

Contracts involving minors or incapacitated persons may be voidable for incapacity. Fraud may also be present if the other party exploited incapacity.

Where incapacity exists, annulment may be based on incapacity, fraud, or both.

LXXXIII. Dolo and Elderly Persons

Fraud against elderly persons may involve:

tricking them into signing deeds;
misrepresenting documents;
isolating them from heirs;
exploiting dependence;
hiding property value;
using false promises of care.

Possible remedies may include annulment, cancellation, reconveyance, guardianship action, damages, or criminal complaint.

LXXXIV. Dolo and Contracts of Adhesion

A contract of adhesion is prepared by one party, with the other party merely accepting or rejecting. Such contracts are not automatically invalid.

However, fraud may exist if important terms are hidden, misrepresented, or deceptively explained.

Courts may construe ambiguities against the party who prepared the contract.

LXXXV. Dolo and Good Faith

Contracts must be performed in good faith. Fraud is the opposite of good faith.

A party who employs fraud may be liable not only for contractual consequences but also for damages based on bad faith, abuse of rights, or other civil law principles.

Good faith is presumed, but fraud rebuts that presumption when proven.

LXXXVI. Dolo and Moral Damages

Moral damages are not automatic in contract disputes. However, where fraud, bad faith, or wrongful conduct causes mental anguish, serious anxiety, wounded feelings, or similar injury, moral damages may be considered if allowed by law and properly proven.

In ordinary breach of contract, moral damages are limited. But fraud may support recovery in proper cases.

LXXXVII. Dolo and Exemplary Damages

Exemplary damages may be awarded by way of example or correction for the public good when the defendant acted in a wanton, fraudulent, reckless, oppressive, or malevolent manner.

If dolo is proven and the conduct is particularly reprehensible, exemplary damages may be considered.

LXXXVIII. Dolo and Attorney’s Fees

Attorney’s fees may be awarded only when legally justified, such as when the defendant’s act compelled the plaintiff to litigate or under other recognized grounds.

Fraud alone does not automatically guarantee attorney’s fees, but it may support the claim if the circumstances justify it.

LXXXIX. Pleading Dolo Causante in a Complaint

A complaint based on dolo causante should allege:

existence of contract;
specific fraudulent acts;
who committed the fraud;
when and how fraud was committed;
why the representations were false;
plaintiff’s reliance;
statement that plaintiff would not have contracted without the fraud;
date of discovery;
absence of ratification;
damages suffered;
prayer for annulment and restitution.

Fraud must be pleaded with particularity. General allegations may be insufficient.

XC. Pleading Dolo Incidente in a Complaint

A complaint based on dolo incidente should allege:

existence of valid contract;
specific incidental fraud;
how fraud affected terms, price, or performance;
damage suffered;
causal connection between fraud and damage;
proof of loss;
prayer for damages, interest, and other proper relief.

The plaintiff should avoid asking for annulment unless fraud truly vitiated consent.

XCI. Sample Allegation for Dolo Causante

“Defendant falsely represented to plaintiff that he was the registered owner of the property and presented a fabricated certificate of title. Relying on said representation, plaintiff entered into the Deed of Sale and paid the purchase price. Plaintiff would not have entered into the contract had he known that defendant was not the owner and that the title was fake. Defendant’s fraudulent representations constituted dolo causante which vitiated plaintiff’s consent.”

XCII. Sample Allegation for Dolo Incidente

“Defendant represented that the equipment had been used for only 500 operating hours, when in truth defendant knew that it had been used for more than 3,000 operating hours. Plaintiff would still have purchased the equipment because it was suitable for plaintiff’s operations, but would have paid a substantially lower price had the true condition been disclosed. Defendant’s misrepresentation constituted dolo incidente, entitling plaintiff to damages equivalent to the overpayment and repair costs.”

XCIII. Defenses Against Dolo Causante

A defendant may argue:

no false representation was made;
statement was opinion or sales talk;
plaintiff did not rely on the statement;
plaintiff knew the truth;
plaintiff conducted independent investigation;
alleged fraud was not material;
plaintiff would have contracted anyway;
plaintiff ratified the contract after discovery;
action prescribed;
plaintiff is in bad faith;
third person committed fraud without defendant’s knowledge;
contract contains disclosures;
plaintiff’s evidence is insufficient.

XCIV. Defenses Against Dolo Incidente

A defendant may argue:

no fraud occurred;
misstatement was immaterial;
plaintiff suffered no damage;
damage was caused by something else;
plaintiff had full opportunity to inspect;
plaintiff accepted the risk;
claim is barred by contract terms;
plaintiff waived the claim after knowledge;
amount of damages is speculative;
plaintiff failed to mitigate damages.

XCV. Dolo and Clean Hands

A party seeking equitable relief should act in good faith.

If both parties engaged in fraud or illegal conduct, the court may refuse relief or apply doctrines preventing recovery.

Example:

A buyer knowingly participates in a simulated transaction to evade taxes, then later claims fraud when the scheme fails. The court may examine whether the buyer comes with clean hands.

XCVI. Dolo and In Pari Delicto

If both parties are equally at fault in an illegal or fraudulent scheme, recovery may be barred under the doctrine of in pari delicto, subject to exceptions.

This may arise where:

both parties used fake documents;
both intended to evade law;
both concealed the true transaction;
both attempted to defraud creditors;
both violated land ownership restrictions.

A party cannot always invoke fraud when they knowingly participated in the wrongdoing.

XCVII. Dolo and Public Policy

Contracts obtained by fraud undermine public policy because they destroy voluntary consent and fair dealing.

However, public policy also protects stability of contracts. Therefore, courts require strong proof before annulling contracts.

This balance explains why dolo causante requires serious, determining fraud, while lesser fraud produces damages only.

XCVIII. Dolo Causante Checklist

To determine whether fraud is dolo causante, ask:

What was the exact false statement or concealment?
Was it material?
Was it known to be false?
Was it made before or during consent?
Did it induce the contract?
Would the deceived party have refused to contract if truth were known?
Was reliance reasonable?
Was the fraud committed by the other contracting party or with their knowledge?
Was the fraud discovered later?
Did the deceived party act promptly?
Was there ratification?
Is annulment still available?

If the answer to the central causation question is yes, dolo causante may exist.

XCIX. Dolo Incidente Checklist

To determine whether fraud is dolo incidente, ask:

Was there fraud?
Did the party still intend to contract?
Would the party have contracted even if truth were known?
Did fraud affect price, terms, quality, timing, or performance?
What specific damage resulted?
Can the damage be quantified?
Is annulment unnecessary or excessive?
Is damages the proper remedy?

If the fraud affected only secondary matters, it is likely incidental.

C. Practical Comparison Through One Example

Suppose a buyer purchases a restaurant business.

Scenario A: Dolo Causante

The seller fabricates permits, invents financial statements, and falsely claims the restaurant has a valid lease. In truth, the lease has expired, permits are revoked, and the business has no legal right to operate. The buyer would not have bought had the truth been known.

This is likely dolo causante. Annulment may be proper.

Scenario B: Dolo Incidente

The restaurant is real, operating, permitted, and profitable. The buyer wants it because of location and customer base. But the seller exaggerates average monthly sales by 10%, causing the buyer to overpay.

The buyer would still have bought, but at a lower price. This is likely dolo incidente. Damages may be proper.

CI. Practical Comparison in Real Property

Scenario A: Dolo Causante

Seller claims the land is titled, clean, and owned by seller. The title is fake and seller owns nothing. Buyer pays because of the fake title.

Fraud caused the sale. Dolo causante.

Scenario B: Dolo Incidente

Seller owns the titled land. Buyer wants it for location. Seller falsely says the perimeter fence is within the boundary, when a small portion encroaches. Buyer would still buy but would have negotiated a lower price.

Fraud is likely incidental. Damages or adjustment may be proper.

CII. Practical Comparison in Employment Settlement

Scenario A: Dolo Causante

An employee signs a quitclaim after HR falsely says the document is only an acknowledgment of receiving final pay and does not waive claims. In truth, it waives all claims. The employee would not have signed had the truth been known.

Dolo causante may invalidate the quitclaim.

Scenario B: Dolo Incidente

Employee knowingly signs a settlement but employer miscomputes one minor component by concealing a small allowance. Employee would still settle but for a slightly higher amount.

Dolo incidente may support additional payment or damages.

CIII. Practical Comparison in Vehicle Sale

Scenario A: Dolo Causante

Seller represents that the car has clean papers and is not stolen. It is stolen and cannot be legally registered. Buyer would not have bought.

Dolo causante.

Scenario B: Dolo Incidente

Seller says the tires are new. They are actually six months old. Buyer would still buy but at a lower price.

Dolo incidente.

CIV. Practical Comparison in Loan

Scenario A: Dolo Causante

Borrower presents a fake land title as collateral, and lender grants loan because of it. Lender would not have lent without the collateral.

Dolo causante.

Scenario B: Dolo Incidente

Borrower slightly overstates monthly income, but lender would still have approved the loan at a lower amount or higher rate.

Dolo incidente.

CV. Dolo and Drafting Contracts

To reduce fraud disputes, parties should:

make representations and warranties explicit;
attach important documents;
require disclosure schedules;
include inspection rights;
state reliance provisions carefully;
require official records;
use escrow for risky transactions;
verify authority;
include remedies for misrepresentation;
document negotiations.

Clear documentation helps prove or disprove dolo.

CVI. Preventing Dolo in Real Estate Transactions

A buyer should:

get certified true copy of title;
verify with Registry of Deeds;
check tax declarations;
inspect property;
verify seller identity;
check marital status;
confirm authority of agent;
check encumbrances;
check pending cases;
avoid full payment before verification;
require notarized documents;
verify possession;
check zoning and permits if material.

Due diligence reduces fraud risk.

CVII. Preventing Dolo in Business Purchases

A buyer should:

inspect financial records;
verify permits;
check tax filings;
review contracts;
verify inventory;
check liabilities;
interview key employees;
examine bank records;
verify ownership of assets;
include warranties;
hold part of price in escrow;
consult accountant and lawyer.

CVIII. Preventing Dolo in Employment and Recruitment

Applicants and employers should verify:

licenses;
credentials;
contracts;
job offers;
authority to recruit;
salary terms;
benefits;
employer identity;
work location;
government approvals.

Fraud in employment or recruitment may have labor, civil, criminal, and administrative consequences.

CIX. What to Do if You Discover Dolo

preserve all documents;
save messages and emails;
obtain certified records;
send written notice or demand;
avoid acts that imply ratification;
determine whether fraud is causante or incidente;
compute damages;
check prescription period;
consult counsel;
file the appropriate case if settlement fails.

Do not delay if annulment may be needed.

CX. Evidence Checklist

Prepare:

signed contract;
drafts and negotiation emails;
advertisements;
messages;
receipts;
payment records;
false documents used;
official records disproving statements;
witness affidavits;
expert reports;
appraisal reports;
photos;
inspection reports;
demand letters;
responses of defendant;
timeline of discovery.

CXI. Demand Letter for Dolo Causante

Subject: Demand for Annulment and Restitution Due to Fraud

Dear [Name]:

I entered into the contract dated [date] based on your representations that [state representation]. I have since discovered that these representations were false, as shown by [evidence].

Your misrepresentations were material and directly induced me to enter into the contract. Had I known the truth, I would not have agreed to the transaction.

I therefore demand cancellation or annulment of the transaction, return of [amount/property], and payment of damages within [number] days from receipt of this letter.

This is without prejudice to civil, criminal, and other remedies.

Sincerely, [Name]

CXII. Demand Letter for Dolo Incidente

Subject: Demand for Damages Due to Incidental Fraud

Dear [Name]:

In relation to our contract dated [date], you represented that [state representation]. I later discovered that this was false. While I would still have entered into the contract, the false representation caused me to agree to terms less favorable to me and caused damages amounting to [amount].

I demand payment of [amount] as damages or appropriate adjustment within [number] days.

This is without prejudice to other legal remedies.

Sincerely, [Name]

CXIII. Choosing the Correct Cause of Action

Before filing, choose the correct theory:

Annulment due to dolo causante if fraud caused consent.
Damages due to dolo incidente if fraud affected only terms.
Breach of contract if the issue is non-performance.
Resolution if breach is substantial in reciprocal obligations.
Rescission if legal grounds for rescission exist.
Reformation if written instrument does not reflect true agreement.
Reconveyance or cancellation of title if registered property was affected.
Criminal complaint if deceit and damage support a crime.

The wrong theory can weaken the case.

CXIV. Frequently Asked Questions

1. What is dolo causante?

Dolo causante is fraud that causes a party to enter into a contract. Without the fraud, the party would not have consented. It makes the contract voidable.

2. What is dolo incidente?

Dolo incidente is fraud that does not cause the contract but affects its terms or incidents. The contract remains valid, but the guilty party may be liable for damages.

3. What is the main difference?

The main difference is causation. In dolo causante, fraud caused consent. In dolo incidente, fraud merely caused disadvantage within a contract the party would still have entered.

4. What is the remedy for dolo causante?

The usual remedy is annulment of the contract, restitution, and damages when proper.

5. What is the remedy for dolo incidente?

The remedy is damages. The contract generally remains valid.

6. Is every lie dolo causante?

No. The lie must be serious and must have induced the contract. Minor or incidental lies usually do not justify annulment.

7. Can silence be fraud?

Yes, if there is a duty to disclose and silence is used to mislead the other party.

8. Can a notarized contract be annulled for fraud?

Yes, but strong evidence is needed. Notarization does not cure fraud.

9. What if I discovered the fraud but continued with the contract?

You may have ratified the contract, especially if you knowingly accepted benefits or performed obligations after discovering the fraud.

10. Can dolo causante also be estafa?

Sometimes. If the facts satisfy criminal elements, a criminal complaint may be possible. But civil fraud and criminal estafa are not identical.

11. Who must prove fraud?

The party alleging fraud must prove it. Fraud is not presumed.

12. What if a broker committed the fraud?

Liability depends on whether the broker acted for a party, whether the principal knew or benefited, and whether the broker had authority. The broker may also be personally liable.

CXV. Conclusion

Dolo causante and dolo incidente are two important forms of fraud under Philippine civil law. Both involve deception, but they have different legal consequences.

Dolo causante is serious fraud that determines consent. It means the deceived party would not have entered into the contract at all without the fraud. The contract is voidable, and the remedy may be annulment, restitution, and damages.

Dolo incidente is incidental fraud. The deceived party would still have entered into the contract, but on different or better terms. The contract remains valid, and the remedy is damages.

The key question is always this: Did the fraud cause the party to enter into the contract, or did it merely affect the terms of a contract the party would still have made?

The answer determines whether the injured party should seek annulment or damages. In practice, the distinction depends on evidence, materiality, reliance, timing, seriousness of deception, and the conduct of the parties after discovering the fraud.
