Quick answer

Before signing, confirm who the parties are, whether the signer has authority, exactly what each side must deliver, when performance is due, how payment and acceptance work, what happens after breach, and how disputes will be resolved. Read every attachment and incorporated policy; unresolved blanks, vague deliverables, one-sided remedies, and verbal assurances are warning signs.

Before enforcing, determine whether the contract is valid and enforceable, whether your own obligations have been performed or properly offered, whether the other party is already in breach or delay, whether written demand is required, and whether the claim must first undergo negotiation, barangay conciliation, mediation, or arbitration. Check the prescriptive period immediately.

Under the Civil Code, contractual obligations generally have the force of law between the parties and must be performed in good faith. But a signature does not automatically validate an illegal agreement, supply missing authority, cure defective consent, or dispense with a form required by law.

The legal foundation of a contract

A contract generally requires all three essential requisites under Article 1318 of the Civil Code of the Philippines:

Consent of the parties;
A certain object or subject matter; and
A lawful cause or basis for each party’s obligation.

Consent ordinarily arises from a definite offer and an absolute acceptance. A purported acceptance that changes material terms is a counteroffer, not an acceptance.

Contracts may be oral, written, electronic, implied from conduct, or contained in several related documents. The general rule is that no particular form is required when the essential requisites exist. Important exceptions apply when the law requires writing, a public instrument, registration, delivery, or another form for validity, enforceability, proof, or effect against third persons.

What to check before signing

1. Identify the correct parties

Use complete and accurate information:

Full legal names, not merely trade names or social-media names;
Civil status when legally relevant;
Current addresses and reliable notice details;
Government-issued identification for individuals;
Exact registered name, registration number, and principal office for a corporation, partnership, or association; and
Tax identification and business-permit information when appropriate to the transaction.

Confirm that the party actually owns, controls, or has the right to sell, lease, license, pledge, or otherwise deal with the subject matter. A convincing representative cannot transfer rights that the principal does not possess.

For land, examine the current title, technical description, annotations, tax declarations, real-property tax records, possession, and the seller’s authority. A title photocopy alone does not establish that it remains current or free from adverse claims.

2. Verify the signer’s authority

A person signing for another must have legal authority. Article 1317 of the Civil Code treats a contract made in another’s name without authority, or beyond the representative’s authority, as unenforceable unless properly ratified before revocation by the other party.

Depending on the party and transaction, request and verify:

A special power of attorney;
Board resolution and secretary’s certificate;
Partnership authorization;
Proof of appointment or incumbency;
Guardianship, estate, or court authority;
The principal’s identification and specimen signature; and
Any legally required spousal or co-owner consent.

Read the authorizing document itself. Authority to negotiate, receive documents, or administer property does not necessarily include authority to sell, mortgage, borrow, compromise, waive claims, or receive payment.

3. Define the subject matter and deliverables precisely

The contract should make it possible to determine what performance is due without inventing terms later. Specify, as applicable:

Quantity, quality, model, specifications, plans, or scope of work;
Property location, title number, boundaries, or unit description;
Milestones, deadlines, schedules, and dependencies;
Required permits, approvals, personnel, or materials;
Delivery location and transfer of possession or risk;
Testing, inspection, acceptance, and rejection procedures;
Warranty scope and duration;
Ownership of work product and intellectual property;
Confidentiality and permitted disclosures; and
Post-termination duties, including return or deletion of property and data.

Avoid phrases such as “as needed,” “industry standard,” “best quality,” or “subject to approval” unless the contract provides an objective standard, decision-maker, timetable, and consequence.

4. Understand the complete price

Check more than the headline amount. The agreement should address:

Currency and whether the amount is VAT-inclusive;
Deposit, down payment, retention, and installment schedule;
Conditions for invoicing and payment;
Taxes, government charges, transfer expenses, and professional fees;
Reimbursable expenses and required documentation;
Price-adjustment formulas;
Interest and penalties;
Refund and forfeiture rules; and
Consequences of disputed invoices.

If interest is charged, ensure the rate and basis are stated in writing. Examine whether penalties, liquidated damages, acceleration clauses, forfeitures, or attorney’s-fee provisions are disproportionate or unclear. Courts may reduce penalties that are iniquitous or unconscionable, but a party should not sign on the assumption that a court will later rewrite the bargain.

5. Match payment to verified performance

Advance payment shifts risk to the payer. For significant transactions, consider safeguards such as:

Milestone billing;
Retention until final acceptance;
Escrow;
Documentary conditions before release;
Performance or warranty security;
Direct verification of the receiving bank account; and
Written acknowledgment for every payment.

Treat a last-minute request to send money to a different person or bank account as a fraud risk. Verify the change using an independent and previously confirmed communication channel.

6. Check conditions and deadlines

Distinguish among:

A fixed obligation already due;
An obligation dependent on a future event;
A condition that must occur before a duty arises;
A milestone that affects only payment; and
A termination event.

Specify whether time is essential, how extensions are approved, and what happens when delay is caused by the other party, government action, force majeure, or a third-party dependency.

Do not leave commencement, delivery, renewal, or expiration dates to implication. Automatic-renewal clauses should state the renewal period and the deadline and method for opting out.

7. Examine representations and disclosures

A representation is useful only if it addresses a material risk and provides a remedy if false. Depending on the transaction, the contract may need statements concerning:

Ownership and absence of undisclosed liens;
Legal capacity and authority;
Required licenses and permits;
Accuracy of financial or technical information;
Pending claims or investigations;
Compliance with law;
Taxes and employment obligations;
Intellectual-property ownership;
Data protection and cybersecurity; and
Conflicts with existing contracts.

Attach or identify material disclosures. A broad statement that a party conducted its own investigation should not be allowed to erase specific representations on which the transaction depends.

8. Read the risk-allocation clauses

Pay particular attention to:

Indemnity;
Limitation or exclusion of liability;
Warranty disclaimers;
Insurance;
Force majeure;
Liquidated damages;
Personal guarantees;
Security interests;
Cross-default and acceleration;
Set-off;
Assignment and subcontracting; and
Waiver and release.

Ask whose negligence, breach, taxes, third-party claims, regulatory violations, and legal expenses each clause covers. Check whether the provision protects both sides or only the drafter.

A waiver of liability for future fraud is void under Article 1171 of the Civil Code. Other limitations may also fail if contrary to law, morals, public order, public policy, or a governing special law.

9. Understand termination and its consequences

A usable termination clause should identify:

Breaches that permit termination;
Whether the breach must be substantial;
Notice and cure periods;
Termination for convenience, if allowed;
The effective date and required method of notice;
Payment for completed or accepted work;
Refund, turnover, and transition duties;
Treatment of deposits and confidential information; and
Provisions that survive termination.

Do not assume that every breach permits immediate cancellation. Article 1191 recognizes resolution of reciprocal obligations for noncompliance, but judicial decisions generally distinguish a substantial and fundamental breach from a slight or casual one. Whether unilateral extrajudicial termination is permissible may depend on the contract, the nature of the breach, governing special laws, and compliance with notice and cure provisions.

10. Review the dispute clause

Determine whether the contract requires:

Negotiation between named representatives;
Mediation;
Arbitration;
Court proceedings;
A particular venue;
A specified governing law; or
Notice within a shortened contractual period.

An arbitration agreement can materially affect where and how a dispute is decided. Review the arbitration rules, seat, number of arbitrators, language, allocation of fees, availability of emergency relief, and enforceability before agreeing.

A venue clause does not necessarily determine which court has subject-matter jurisdiction. Jurisdiction is conferred by law, not by private agreement.

11. Confirm the signing formalities

Before execution:

Remove blanks or mark them “not applicable”;
Check all names, dates, amounts, schedules, and cross-references;
Attach every annex and initial material corrections;
Ensure all parties sign the same final version;
Obtain signed counterparts for everyone;
Use witnesses when appropriate;
Determine whether notarization, acknowledgment, registration, or government approval is required; and
Keep proof of delivery and acceptance of the signed contract.

Notarization does not automatically make an illegal, simulated, unauthorized, or otherwise defective agreement valid. It can convert a private document into a public document and strengthen its evidentiary character, but the notary must comply with the applicable notarial rules, including personal appearance and proper identification.

Certain transactions require special formalities. Examples include donations of immovable property, specified donations of movable property, authority to sell land through an agent, real-estate transactions requiring registration, mortgages, and contracts subject to sector-specific laws. Obtain transaction-specific advice rather than relying on a generic template.

Oral and electronic contracts

Oral agreements

An oral contract may be valid, but proving its terms and enforcement can be difficult. Article 1403 of the Civil Code’s Statute of Frauds requires a signed writing or sufficient memorandum for certain executory agreements, including, among others:

An agreement that cannot be performed within one year;
A special promise to answer for another person’s debt or default;
Certain agreements made in consideration of marriage;
A lease longer than one year;
A sale of real property or an interest in it; and
Other transactions identified in the provision.

The Statute of Frauds generally concerns executory agreements, not agreements that have already been fully or partly performed. Acceptance of benefits or failure to object to oral evidence may also amount to ratification under Article 1405. The precise effect depends on the agreement and acts of performance.

Put important agreements in writing even when an oral contract might technically be valid.

Electronic contracts and signatures

The Electronic Commerce Act, Republic Act No. 8792, recognizes electronic data messages, electronic documents, electronic signatures, and contracts formed electronically, subject to statutory requirements on integrity, reliability, attribution, and authentication. A contract cannot be denied validity solely because it is electronic.

However, electronic form does not eliminate formalities that another law requires for validity. Preserve:

The complete signed file;
Audit trail and signature certificate;
Emails transmitting the document;
Account and device information available from the signing platform;
Date-and-time records;
Earlier drafts and tracked changes; and
Evidence that the signer controlled or authorized the account used.

A typed name, clicked button, email response, or platform signature may have legal consequences, but authenticity and intent may still need proof.

What to check before enforcing the contract

1. Identify the exact binding documents

Assemble the signed contract and every incorporated document:

Amendments and addenda;
Purchase orders;
Statements of work;
Technical specifications;
Approved change orders;
Policies expressly incorporated by reference;
Guarantees and security documents;
Notices; and
Relevant electronic communications.

Confirm which document prevails if provisions conflict. Do not enforce a quotation, draft, or expired offer when a later agreement replaced it.

2. Confirm that the obligation is due

Ask:

Has the due date arrived?
Did a condition precedent occur?
Was required notice given?
Was the deliverable properly submitted?
Did the other side have a valid cure period?
Has the obligation been extended, waived, novated, settled, or paid?
Did your side cause or contribute to the nonperformance?

In reciprocal obligations, one party ordinarily cannot place the other in delay while failing or refusing to perform its corresponding obligation. Document your performance, readiness to perform, or legally justified withholding.

3. Classify the breach

Identify the contractual promise violated and the supporting evidence. Common breaches include:

Nonpayment;
Late delivery;
Defective or incomplete work;
Unauthorized disclosure;
Violation of exclusivity or non-solicitation terms;
False representations;
Failure to obtain an approval or permit;
Unauthorized assignment; and
Repudiation before performance is due.

The remedy depends on whether the breach is slight, substantial, curable, continuing, anticipatory, or expressly treated by the contract as a termination event.

4. Determine whether demand is necessary

Article 1169 of the Civil Code generally places an obligor in delay from judicial or extrajudicial demand. Demand may be unnecessary when:

The contract or law expressly provides that delay begins without demand;
Timing was a controlling reason for the agreement; or
Demand would be useless because performance has been made impossible.

Even when demand may not be legally indispensable, a clear written demand often helps establish the breach, amount claimed, requested cure, and date of receipt.

A proper demand should ordinarily state:

The contract and parties;
The specific obligation and clause violated;
Relevant dates and facts;
The amount or performance due, with computation;
The remedy requested;
A reasonable or contractually required deadline;
The action contemplated after noncompliance; and
A reservation of rights.

Avoid threats, public shaming, exaggerated criminal accusations, or demands for amounts unsupported by the contract or law.

5. Choose an available remedy

Depending on the contract, breach, and governing law, remedies may include:

Specific or exact performance;
Completion or correction at the breaching party’s cost;
Collection of an unpaid amount;
Damages proven to have resulted from the breach;
Enforcement of a valid penalty or liquidated-damages clause;
Resolution or termination of reciprocal obligations;
Restitution or refund;
Injunction, attachment, or another provisional remedy;
Enforcement of security or a guarantee; and
Reformation, annulment, declaration of nullity, or rescission in legally appropriate cases.

Article 1170 makes a party liable for damages when, in performing an obligation, that party is guilty of fraud, negligence, delay, or violation of the agreement’s terms. Recoverable damages are not automatically equal to every loss alleged; causation, foreseeability, certainty, mitigation, contractual limitations, and proof matter.

Attorney’s fees are not automatically recoverable merely because a party wins. Article 2208 permits them only when stipulated or when a statutory exception applies, and the amount must remain reasonable.

6. Follow the agreed and legally required process

Check the contract’s notice address, authorized delivery method, cure period, escalation procedure, mediation requirement, and arbitration clause.

Barangay conciliation may be a condition before filing in court when the dispute falls within the lupon’s authority. Section 412 of the Local Government Code also recognizes exceptions, including cases involving detention, habeas corpus, specified provisional remedies, or a claim that may otherwise prescribe.

Claims solely for payment or reimbursement of money not exceeding the current small-claims ceiling may qualify for the Supreme Court’s small claims procedure, subject to the governing rules and exclusions. Other civil actions follow the applicable rules on jurisdiction, venue, pleading, evidence, and pre-trial.

Prescriptive periods: do not wait

Under Articles 1144 and 1145 of the Civil Code, the general periods are:

Ten years for an action based on a written contract; and
Six years for an action based on an oral contract.

The period is generally counted from when the cause of action accrues—when the right can legally be enforced—not automatically from the signing date. Special laws, the nature of the remedy, installment obligations, acknowledgments, arbitration rules, and other circumstances may produce a different period.

Article 1155 states that prescription is interrupted by:

Filing an action in court;
A written extrajudicial demand by the creditor; or
A written acknowledgment of the debt by the debtor.

Do not assume that informal follow-ups, negotiations, partial correspondence, an internal complaint, or a demand sent to the wrong person safely preserves the claim. If a deadline may be near, obtain legal advice immediately.

Evidence to preserve

Keep originals where available and make secure backups of:

The signed contract and every page and annex;
Drafts showing negotiated changes;
Signature records and notarization details;
Proof of authority of representatives;
Invoices, official receipts, bank records, and payment references;
Delivery receipts, inspection reports, and acceptance documents;
Photographs and videos of property, goods, or work;
Emails, text messages, chat exports, and call records;
Notices, demands, courier receipts, and proof of electronic delivery;
Change orders and approvals;
Complaints, warranty requests, and responses;
Computations of principal, interest, penalties, and losses; and
Evidence of steps taken to reduce or avoid further loss.

Preserve complete conversations rather than isolated screenshots. Retain metadata and original files. Do not alter documents, backdate signatures, create reconstructed receipts, or access another person’s account without authority.

Common mistakes

Signing without reading annexes, hyperlinks, or incorporated policies;
Trusting verbal promises that contradict the written contract;
Leaving blanks to be filled in later;
Failing to verify the counterparty, asset, title, permit, or signer’s authority;
Paying to an unverified personal or newly substituted account;
Treating notarization as proof that the transaction is lawful;
Assuming any electronic signature is automatically authentic;
Ignoring automatic renewal, arbitration, exclusivity, guarantee, or acceleration clauses;
Continuing performance after a serious breach without reserving rights;
Terminating immediately without observing notice and cure requirements;
Demanding payment without proving one’s own performance;
Confusing contract resolution with a right to seize property or use force;
Posting accusations online instead of using lawful remedies;
Assuming every breach is fraud or estafa;
Computing interest or penalties without a contractual or legal basis; and
Allowing prescription to run while negotiations continue.

When legal help is urgent

Seek prompt, transaction-specific advice when:

A signing, payment, renewal, cancellation, or filing deadline is near;
Land, a home, inheritance, corporate control, intellectual property, or a large investment is involved;
The signer’s authority or the owner’s identity is doubtful;
A party requests backdating, false receipts, hidden side agreements, or payment to an unrelated account;
Consent may have resulted from fraud, intimidation, mistake, or undue influence;
The contract contains a personal guarantee, mortgage, confession of judgment, broad indemnity, or major liability waiver;
The agreement requires arbitration or foreign proceedings;
Assets may be transferred, concealed, damaged, or disposed of;
Immediate injunctive relief, attachment, or recovery of property may be necessary;
The counterparty is insolvent, dissolved, deceased, or leaving the Philippines;
A government permit, franchise, license, or regulatory approval is material; or
Prescription may expire soon.

Frequently asked questions

Is a contract valid even if it is not notarized?

Often, yes. Many contracts are valid between the parties once the essential requisites exist, even without notarization. Some transactions, however, require a particular form for validity or enforceability, or a public instrument and registration to affect third persons. The correct answer depends on the type of contract.

Can I cancel because the other party breached?

Possibly, but not every breach justifies cancellation. Review whether the breach is substantial, whether a cure period applies, whether your own obligations were performed, and whether the contract permits extrajudicial termination. Some remedies require court or arbitral action.

Does signing mean I can no longer challenge the contract?

No. A signed contract may still be questioned on grounds such as incapacity, lack or excess of authority, mistake, fraud, intimidation, undue influence, illegality, simulation, absence of an essential requisite, or failure to observe a legally indispensable form. Proof and applicable deadlines remain critical.

Are chat messages enough to prove an agreement?

They can help establish an offer, acceptance, authority, terms, admissions, or performance. Their weight depends on completeness, authenticity, attribution, context, and compliance with evidentiary rules. Preserve the original conversation and associated account and device records.

Is a demand letter always required before filing?

Not always. It may be required by the contract or necessary to place the debtor in delay, although Article 1169 recognizes exceptions. Other preconditions—such as barangay conciliation, mediation, or arbitration—may separately apply.

Can the winning party automatically recover attorney’s fees?

No. Attorney’s fees require a valid stipulation or a legal basis under provisions such as Article 2208, and any award must be reasonable and supported by the circumstances.

Can a party refuse performance because the other side has not performed?

In a reciprocal contract, a party’s nonperformance may justify withholding corresponding performance, but the answer depends on the sequence of obligations, conditions, severity of breach, and contract terms. Give written notice and avoid taking irreversible action without reviewing the agreement.

Can parties agree that no demand is necessary?

Yes. A contract may expressly state that delay begins upon the due date without further demand. The language should be clear, and enforcement remains subject to law and the facts.
