I. Introduction

Obligations are among the most fundamental concepts in Philippine civil law. They govern the legal relationships by which one person may demand from another the giving of something, the doing of an act, or the refraining from an act. Nearly every private legal transaction—contracts of sale, leases, loans, employment arrangements, agency, damages, restitution, and family property relations—rests on the law of obligations.

The principal source of Philippine law on obligations is the Civil Code of the Philippines, particularly Book IV, Title I, beginning with Article 1156. The Civil Code defines an obligation as:

A juridical necessity to give, to do, or not to do.

This definition is concise but significant. An obligation is not merely a moral duty, social expectation, or personal promise. It is a juridical necessity, meaning it is enforceable by law. If the obligor fails to comply, the creditor may seek legal remedies.

II. Concept of Obligation

An obligation is a legal bond between two or more persons, where one party is bound to perform a prestation in favor of another.

In ordinary language, an obligation may mean any duty. In law, however, an obligation has a technical meaning. It refers to a relationship where one party, called the creditor or obligee, may legally demand performance from another party, called the debtor or obligor.

The Civil Code definition emphasizes three possible objects of an obligation:

To give — delivery of a thing.
To do — performance of an act or service.
Not to do — abstention from an act.

Thus, an obligation may require the debtor to deliver a car, build a house, pay money, render services, refrain from competing, or avoid constructing on another’s land.

III. Essential Elements of an Obligation

For an obligation to exist, four essential elements must be present:

1. Active Subject

The active subject is the person who has the right to demand performance. This party is also called the creditor or obligee.

The active subject is the holder of the right. For example, in a contract of loan, the lender is the creditor who may demand repayment.

2. Passive Subject

The passive subject is the person who is bound to perform the obligation. This party is also called the debtor or obligor.

The passive subject bears the legal duty. In a contract of sale, the seller may be the debtor with respect to the obligation to deliver the thing sold, while the buyer may be the debtor with respect to the obligation to pay the price.

3. Object or Prestation

The object or prestation is the conduct required from the debtor. It may consist of:

giving something;
doing something; or
not doing something.

The prestation must be possible, lawful, determinate or determinable, and capable of pecuniary estimation.

4. Juridical or Legal Tie

The juridical tie, also known as the vinculum juris, is the legal bond that connects the creditor and debtor. It is the reason why the creditor may compel performance and why the debtor is legally bound.

Without the juridical tie, there may be a moral or social duty, but there is no civil obligation enforceable in court.

IV. Sources of Obligations

Under Article 1157 of the Civil Code, obligations arise from:

Law
Contracts
Quasi-contracts
Acts or omissions punished by law
Quasi-delicts

These are exclusive sources. A person cannot be made civilly liable unless the obligation is traceable to one of these recognized sources.

V. Obligations Arising from Law

Obligations derived from law are not presumed. They must be expressly or impliedly established by statute.

Examples include:

the obligation to pay taxes;
the obligation of parents to support their children;
the obligation of co-owners to contribute to expenses of preservation;
the obligation of an employer to comply with labor standards;
the obligation to indemnify in cases expressly provided by law.

Obligations arising from law are governed primarily by the law that creates them. The Civil Code applies suppletorily only when appropriate.

VI. Obligations Arising from Contracts

A contract is a meeting of minds between two persons whereby one binds himself, with respect to the other, to give something or to render some service.

Under Article 1159, obligations arising from contracts have the force of law between the contracting parties and should be complied with in good faith.

This principle reflects the doctrine of autonomy of contracts. Parties are generally free to establish stipulations, clauses, terms, and conditions, provided they are not contrary to law, morals, good customs, public order, or public policy.

Requisites of a Contract

A valid contract generally requires:

Consent
Object
Cause

Once a contract is perfected, the parties are bound not only to what has been expressly stipulated but also to all consequences that, according to their nature, are in keeping with good faith, usage, and law.

VII. Obligations Arising from Quasi-Contracts

A quasi-contract is a juridical relation arising from lawful, voluntary, and unilateral acts, by virtue of which the parties become bound to each other to prevent unjust enrichment.

The two principal quasi-contracts under the Civil Code are:

1. Negotiorum Gestio

This occurs when a person voluntarily manages the property or affairs of another without authority.

For example, if a neighbor undertakes urgent repairs to another person’s property during the owner’s absence to prevent serious damage, the law may create obligations between them.

2. Solutio Indebiti

This occurs when something is received when there is no right to demand it, and it was unduly delivered through mistake.

For example, if a person mistakenly pays a debt to someone who is not the creditor, the recipient may be obliged to return what was received.

The foundation of quasi-contract is equity: no one should unjustly enrich himself at the expense of another.

VIII. Obligations Arising from Crimes

Civil obligations may also arise from acts or omissions punished by law.

When a person commits a crime, he may incur both:

criminal liability, which is owed to the State; and
civil liability, which is owed to the offended party.

Civil liability arising from crime may include:

Restitution;
Reparation for damage caused;
Indemnification for consequential damages.

For example, a person convicted of theft may be required not only to suffer the criminal penalty but also to return the stolen property or pay its value.

The civil liability arising from crime is governed by penal laws and relevant provisions of the Civil Code.

IX. Obligations Arising from Quasi-Delicts

A quasi-delict arises when a person, by act or omission, causes damage to another through fault or negligence, there being no pre-existing contractual relation between the parties.

The essential requisites of quasi-delict are:

An act or omission;
Fault or negligence;
Damage caused to another;
Causal connection between the fault or negligence and the damage;
Absence of a pre-existing contractual relation regarding the act complained of.

A common example is a vehicular accident caused by negligent driving. The injured party may sue for damages based on quasi-delict.

Quasi-delict is distinct from breach of contract. In contractual negligence, the obligation already exists before the negligent act. In quasi-delict, the negligent act itself gives rise to the obligation.

X. Kinds of Obligations According to the Prestation

A. Obligation to Give

An obligation to give requires the delivery of a thing.

The thing may be:

Determinate or specific — particularly designated or physically segregated from all others of the same class.
Generic or indeterminate — designated only by class or genus.

Example of a determinate thing: “I will deliver my 2020 Toyota Vios with plate number ABC 1234.”

Example of a generic thing: “I will deliver 100 sacks of rice.”

The distinction is important because the loss of a determinate thing without the debtor’s fault may extinguish the obligation, while the loss of a generic thing generally does not. The principle is commonly expressed as: genus never perishes.

Duties of a Debtor in an Obligation to Give a Determinate Thing

The debtor must:

Preserve the thing with the diligence of a good father of a family;
Deliver the thing itself;
Deliver its accessions and accessories;
Deliver the fruits from the time the obligation to deliver arises;
Answer for damages in case of fraud, negligence, delay, or contravention of the tenor of the obligation.

B. Obligation to Do

An obligation to do requires the performance of an act.

Examples:

building a house;
repairing a vehicle;
rendering professional services;
painting a portrait;
transporting goods.

If the debtor fails to perform, the creditor may generally have the obligation executed at the debtor’s cost, unless the obligation is purely personal and substitution would be improper.

If the act is done poorly, in contravention of the agreement, it may be ordered undone, or damages may be awarded.

C. Obligation Not to Do

An obligation not to do requires abstention.

Examples:

not to build beyond a certain height;
not to disclose confidential information;
not to compete within a valid contractual limitation;
not to enter a particular property.

If the debtor performs the prohibited act, it may be ordered undone at his expense, where possible, without prejudice to damages.

XI. Nature and Effect of Obligations

The Civil Code establishes rules on the effect of obligations, particularly in cases of fraud, negligence, delay, and breach.

A. Responsibility for Fraud

Fraud, or dolo, refers to deliberate or intentional evasion of the normal fulfillment of an obligation.

Responsibility arising from fraud is demandable in all obligations. Any waiver of an action for future fraud is void.

Fraud must be distinguished from negligence. Fraud involves intent; negligence involves lack of due care.

B. Responsibility for Negligence

Negligence, or culpa, is the omission of the diligence required by the nature of the obligation and corresponding to the circumstances of persons, time, and place.

If the law or contract does not state the required diligence, the standard is generally the diligence of a good father of a family, meaning ordinary diligence expected of a reasonably prudent person.

Negligence may occur in:

Contracts;
Quasi-delicts;
Crimes, in the form of criminal negligence.

C. Delay

Delay, or mora, occurs when the debtor fails to perform the obligation on time and legal delay has set in.

As a general rule, there is no delay unless the creditor judicially or extrajudicially demands performance. Demand may be made through a court action, letter, verbal demand, or other clear communication.

However, demand is not necessary when:

The obligation or law expressly so declares;
Time is of the essence;
Demand would be useless;
The debtor has rendered performance beyond his power;
In reciprocal obligations, one party performs or is ready to perform and the other does not.

Kinds of Delay

Mora solvendi — delay on the part of the debtor.
Mora accipiendi — delay on the part of the creditor.
Compensatio morae — delay in reciprocal obligations, where both parties are in default.

D. Contravention of the Tenor of the Obligation

A debtor may also be liable when he violates the terms, conditions, or manner of performance required by the obligation.

This includes defective, partial, improper, or unauthorized performance.

XII. Real Obligations and Personal Obligations

Obligations may be classified as real or personal.

Real Obligation

A real obligation is an obligation to give. It involves delivery of a thing.

Example: A seller’s obligation to deliver the property sold.

Personal Obligation

A personal obligation is an obligation to do or not to do.

Example: A contractor’s obligation to construct a building, or a lessee’s obligation not to sublease the premises.

XIII. Determinate and Generic Obligations

Determinate Obligation

An obligation is determinate when the object is specifically designated or physically segregated.

Example: “I will deliver the painting titled X by artist Y.”

If the determinate thing is lost without the debtor’s fault and before delay, the obligation may be extinguished.

Generic Obligation

An obligation is generic when the object is identified only by class or genus.

Example: “I will deliver 50 kilos of sugar.”

A generic obligation is not extinguished by the loss of the thing because another thing of the same kind may be delivered.

XIV. Pure and Conditional Obligations

Pure Obligation

A pure obligation is one whose performance does not depend on a condition or period. It is demandable at once.

Example: “I promise to pay you ₱100,000.”

If no condition or term is attached, the creditor may immediately demand payment.

Conditional Obligation

A conditional obligation depends upon the happening of a future and uncertain event, or upon a past event unknown to the parties.

Conditions may be:

Suspensive — the obligation arises only upon fulfillment of the condition.
Resolutory — the obligation is immediately demandable but extinguished upon fulfillment of the condition.

Example of suspensive condition: “I will give you my car if you pass the bar examination.”

Example of resolutory condition: “You may use my property until I return from abroad.”

XV. Potestative, Casual, and Mixed Conditions

Conditions may also be classified according to their dependence on will or chance.

Potestative Condition

A potestative condition depends upon the will of one of the parties.

If the fulfillment of a suspensive condition depends solely on the will of the debtor, the conditional obligation is void. This prevents the debtor from binding himself while retaining complete control over whether the obligation will ever arise.

Casual Condition

A casual condition depends upon chance or the will of a third person.

Example: “I will donate ₱50,000 if a typhoon damages the school building.”

Mixed Condition

A mixed condition depends partly on the will of a party and partly on chance or the will of a third person.

Example: “I will give you a bonus if you secure approval from the regulatory agency.”

XVI. Obligations with a Period

An obligation with a period is one whose demandability or extinguishment depends upon the arrival of a future and certain event.

The event must be certain to happen, although the exact date may be uncertain.

Example: “I will pay you on June 30, 2026.”

A period may be:

Suspensive or ex die — the obligation begins only upon arrival of the period.
Resolutory or in diem — the obligation is demandable at once but terminates upon arrival of the period.

The period is generally presumed to benefit both creditor and debtor, unless the tenor of the obligation or circumstances show that it was established for the benefit of one party only.

XVII. Alternative and Facultative Obligations

Alternative Obligation

An alternative obligation has several prestations, but the debtor is required to perform only one.

Example: “I will deliver either my laptop, my tablet, or ₱30,000.”

As a general rule, the right of choice belongs to the debtor, unless expressly granted to the creditor.

Once the choice is communicated, the obligation becomes simple and limited to the chosen prestation.

Facultative Obligation

A facultative obligation has only one principal prestation, but the debtor may substitute another.

Example: “I will deliver my motorcycle, but I may instead pay ₱80,000.”

The distinction is important. In an alternative obligation, several prestations are due until one is chosen. In a facultative obligation, only the principal prestation is due, while the substitute is merely a permitted replacement.

XVIII. Joint and Solidary Obligations

When there are multiple creditors or debtors, the obligation may be joint or solidary.

Joint Obligation

In a joint obligation, each debtor is liable only for his proportionate share, and each creditor may demand only his proportionate share.

Joint obligations are presumed unless solidarity is expressly stated, required by law, or clearly intended by the nature of the obligation.

Example: A, B, and C owe X ₱90,000 jointly. Each debtor is liable only for ₱30,000.

Solidary Obligation

In a solidary obligation, each debtor may be required to pay the entire obligation, or each creditor may demand the entire prestation.

Example: A, B, and C bind themselves solidarily to pay X ₱90,000. X may demand the full ₱90,000 from A alone, without prejudice to A’s right to seek reimbursement from B and C.

Solidarity may be:

Active solidarity — among creditors;
Passive solidarity — among debtors;
Mixed solidarity — among both creditors and debtors.

Solidary obligations are not presumed.

XIX. Divisible and Indivisible Obligations

Divisible Obligation

An obligation is divisible when it is capable of partial performance.

Example: Payment of ₱100,000 may be divided into installments.

Indivisible Obligation

An obligation is indivisible when partial performance is not possible because of the nature of the prestation, law, or agreement.

Example: Delivery of a particular car is indivisible.

Divisibility should not be confused with plurality of parties. An obligation may be divisible in prestation but joint in parties, or indivisible in prestation but not solidary in liability.

XX. Obligations with a Penal Clause

An obligation with a penal clause is one where an accessory undertaking imposes a penalty in case of breach.

Example: “If the contractor fails to finish the building by June 30, he shall pay ₱10,000 per day of delay.”

The penalty generally substitutes for damages and interest unless otherwise stipulated. However, damages may still be recovered when:

The parties so agreed;
The debtor refuses to pay the penalty;
The debtor is guilty of fraud.

Courts may reduce the penalty when it is iniquitous, unconscionable, or when there has been partial or irregular performance.

XXI. Extinguishment of Obligations

Under Article 1231 of the Civil Code, obligations are extinguished by:

Payment or performance;
Loss of the thing due;
Condonation or remission of the debt;
Confusion or merger of rights;
Compensation;
Novation.

Other causes may also extinguish obligations, such as annulment, rescission, fulfillment of a resolutory condition, and prescription.

XXII. Payment or Performance

Payment means not only delivery of money but also complete performance of the obligation.

For payment to extinguish an obligation, there must generally be:

Identity of prestation;
Integrity or completeness of prestation;
Indivisibility of payment, unless partial payment is allowed.

A creditor cannot be compelled to receive a different thing from that which is due, even if it is of equal or greater value. Neither may the debtor compel the creditor to accept partial performance, unless the obligation permits it.

Payment by a Third Person

A third person may pay the obligation, whether or not he has an interest in its fulfillment, subject to rules on reimbursement and subrogation.

If payment is made without the debtor’s knowledge or against his will, the third person’s rights may be limited.

XXIII. Application of Payments

Application of payments applies when:

There is one debtor;
There is one creditor;
There are several debts;
The debts are of the same kind;
The debts are due;
The payment is insufficient to cover all debts.

The debtor generally has the first right to designate which debt is being paid. If the debtor does not make the application, the creditor may do so by issuing a receipt. If neither applies the payment, the law determines the application.

XXIV. Dation in Payment

Dation in payment, or dacion en pago, occurs when property is alienated to the creditor in satisfaction of a monetary debt.

Example: A debtor who owes ₱1,000,000 transfers a parcel of land to the creditor as payment.

Dation in payment is similar to a sale because ownership of property is transferred to satisfy an obligation.

XXV. Payment by Cession

Payment by cession occurs when a debtor assigns all his property to his creditors so that the proceeds may be applied to his debts.

Unlike dation in payment, payment by cession does not automatically transfer ownership to the creditors. The creditors are generally authorized to sell the debtor’s property and apply the proceeds to the debts.

XXVI. Tender of Payment and Consignation

When the creditor unjustly refuses to accept payment, the debtor may be released through tender of payment and consignation.

Tender of Payment

Tender of payment is the debtor’s offer to pay.

Consignation

Consignation is the deposit of the thing or amount due with the proper court.

As a rule, tender of payment must precede consignation. However, tender may not be required in certain cases, such as when the creditor is absent, incapacitated, refuses to issue a receipt, or when several persons claim the right to collect.

Consignation, properly made, may extinguish the obligation.

XXVII. Loss of the Thing Due

An obligation to deliver a determinate thing may be extinguished if the thing is lost or destroyed without the debtor’s fault and before he incurs delay.

However, the debtor remains liable if:

The loss occurred through his fault;
He was already in delay;
He promised to deliver the same thing to two or more persons with different interests;
The obligation arises from a criminal offense;
The law or stipulation provides otherwise.

In generic obligations, loss generally does not extinguish the obligation because another thing of the same kind may be delivered.

XXVIII. Condonation or Remission

Condonation or remission is the gratuitous abandonment by the creditor of his right.

It may be:

Express — clearly stated;
Implied — inferred from acts of the creditor.

Because condonation is essentially gratuitous, it is subject to rules on donations. The debtor must accept the remission for it to be effective.

XXIX. Confusion or Merger

Confusion occurs when the characters of creditor and debtor are merged in the same person with respect to the same obligation.

Example: A owes B ₱100,000. Later, A becomes B’s sole heir and inherits B’s credit. The obligation is extinguished because A cannot be both creditor and debtor of the same obligation.

XXX. Compensation

Compensation occurs when two persons are creditors and debtors of each other.

Example: A owes B ₱100,000. B owes A ₱70,000. The debts may be compensated up to ₱70,000, leaving A liable for ₱30,000.

Requisites of Legal Compensation

Legal compensation generally requires:

Each party must be a principal creditor and principal debtor of the other;
Both debts must consist of money or consumable things of the same kind and quality;
Both debts must be due;
Both debts must be liquidated and demandable;
There must be no retention or controversy commenced by third persons and communicated in due time to the debtor.

Compensation may be total or partial.

XXXI. Novation

Novation is the extinguishment of an obligation by the creation of a new one that substitutes it.

Novation may be:

Objective or real — change in the object or principal conditions;
Subjective or personal — change in the debtor or creditor;
Mixed — change in both object and parties.

Novation is never presumed. It must be clearly shown either by express agreement or by incompatibility between the old and new obligations.

XXXII. Breach of Obligations

A breach occurs when the debtor fails to comply with the obligation according to its terms.

Breach may consist of:

Complete non-performance;
Partial performance;
Defective performance;
Delayed performance;
Performance contrary to the terms of the obligation.

The injured party may seek remedies depending on the nature of the obligation and the source of liability.

XXXIII. Remedies for Breach

The principal remedies include:

1. Specific Performance

Specific performance compels the debtor to perform the obligation.

This is common in obligations to give a determinate thing.

2. Substitute Performance

In obligations to do, if the debtor fails to perform, the creditor may have the obligation performed by another at the debtor’s expense, when substitution is legally and practically possible.

3. Undoing of Prohibited or Defective Acts

In obligations not to do, or obligations done contrary to agreement, the court may order the act undone if possible.

4. Rescission or Resolution

In reciprocal obligations, the injured party may choose between fulfillment and rescission, with damages in either case.

This remedy is especially important in contracts of sale, leases, construction contracts, and other reciprocal arrangements.

5. Damages

Damages may be awarded for loss or injury caused by breach. Depending on the case, damages may include actual, moral, nominal, temperate, liquidated, or exemplary damages.

XXXIV. Reciprocal Obligations

Reciprocal obligations arise from the same cause, where each party is a debtor and creditor of the other.

Example: In a sale, the seller must deliver the thing, while the buyer must pay the price.

The power to rescind reciprocal obligations is implied when one party does not comply with what is incumbent upon him. The injured party may choose between:

fulfillment; or
rescission,

with damages in either case.

Reciprocity is important because delay generally begins when one party performs or is ready to perform and the other does not.

XXXV. Damages in Obligations

Damages are monetary compensation for loss or injury.

A. Actual or Compensatory Damages

These compensate for proven pecuniary loss. The claimant must generally prove both the fact and amount of loss.

B. Moral Damages

These compensate for physical suffering, mental anguish, fright, serious anxiety, besmirched reputation, wounded feelings, moral shock, social humiliation, and similar injury.

Moral damages are not recoverable in every breach of contract. They require legal basis.

C. Nominal Damages

These are awarded when a legal right has been violated but no substantial loss is proven.

D. Temperate or Moderate Damages

These are awarded when some pecuniary loss has been suffered but its exact amount cannot be proven with certainty.

E. Liquidated Damages

These are damages agreed upon by the parties in advance, usually through a penal clause.

F. Exemplary or Corrective Damages

These are imposed by way of example or correction for the public good, generally when the defendant’s conduct is wanton, fraudulent, reckless, oppressive, or malevolent.

XXXVI. Fortuitous Events

A fortuitous event is an event that could not be foreseen, or though foreseen, was inevitable.

As a general rule, no person is responsible for fortuitous events.

However, the debtor may still be liable when:

The law provides liability;
The contract provides liability;
The nature of the obligation requires assumption of risk;
The debtor is guilty of negligence;
The debtor is in delay;
The debtor has promised the same determinate thing to several persons with different interests.

Examples may include earthquakes, extraordinary floods, war, or other events beyond human control, depending on the circumstances.

Not every difficulty, price increase, inconvenience, or business loss is a fortuitous event. The event must be independent of the debtor’s will and must make performance impossible, not merely burdensome.

XXXVII. Civil Liability Distinguished from Natural and Moral Obligations

Civil Obligation

A civil obligation is enforceable by court action.

Example: A written loan payable on a fixed date.

Natural Obligation

A natural obligation is based on equity and natural law but is not enforceable by court action. However, once voluntarily performed, the debtor cannot recover what has been delivered or paid.

Example: Payment of a debt that has already prescribed.

Moral Obligation

A moral obligation is based on conscience, ethics, or social duty but has no necessary legal effect.

Example: A promise to help a friend without legal consideration or binding source.

XXXVIII. Essential Requisites of a Valid Prestation

The object or prestation of an obligation must have certain qualities.

1. It Must Be Possible

The prestation must be physically and legally possible.

An obligation to perform an impossible act is void if the impossibility exists from the beginning.

2. It Must Be Lawful

The prestation must not be contrary to law, morals, good customs, public order, or public policy.

Example: An agreement to commit a crime or suppress prosecution is void.

3. It Must Be Determinate or Determinable

The prestation must be identified or at least capable of being determined without need of a new agreement.

Example: “I will sell you one of my cars” may require further determination. “I will sell you my only car” is determinate.

4. It Must Have Pecuniary Value

The prestation must be capable of economic valuation. This does not mean it must always involve money, but breach must be compensable in some legally recognizable way.

XXXIX. Good Faith in Obligations

Good faith is a pervasive principle in the law of obligations.

Parties must not only comply with the literal terms of their obligations but must also act honestly, fairly, and consistently with the reasonable expectations arising from the relationship.

Bad faith may increase liability and justify damages.

Good faith is especially important in:

performance of contracts;
interpretation of ambiguous stipulations;
exercise of rights;
termination of contractual relations;
enforcement of remedies.

The Civil Code rejects the abusive exercise of rights. A person who exercises a right solely to prejudice another may be liable for damages.

XL. Abuse of Rights and Human Relations Provisions

The Civil Code includes provisions on human relations that affect obligations.

A person must act with justice, give everyone his due, and observe honesty and good faith. One who willfully or negligently causes damage to another contrary to morals, good customs, or public policy may be liable.

These provisions are significant because they expand civil liability beyond strict contractual or property relations. They emphasize fairness, honesty, and social responsibility.

XLI. Interpretation of Obligations

When the terms of an obligation are clear, the literal meaning generally controls. However, when ambiguity exists, courts may consider the intention of the parties, contemporaneous and subsequent acts, usage, and equity.

In contracts, obscure words or stipulations are generally interpreted against the party who caused the ambiguity.

The goal is to give effect to the true intent of the parties, provided such intent is lawful.

XLII. Obligations in Common Transactions

A. Sale

In a sale, the seller is obliged to transfer ownership and deliver the thing sold, while the buyer is obliged to pay the price.

The obligation is reciprocal.

B. Lease

In a lease, the lessor must allow the lessee to enjoy the thing leased, while the lessee must pay rent and use the property according to the agreement.

C. Loan

In a simple loan or mutuum, the borrower acquires ownership of money or consumable goods and must return the same amount or quality.

In commodatum, the borrower uses a non-consumable thing and must return the identical thing.

D. Agency

In agency, the agent binds himself to render service or do something in representation of the principal, with the principal’s consent or authority.

E. Deposit

In deposit, the depositary receives a thing belonging to another and assumes the obligation to safely keep it and return it.

F. Partnership

In partnership, persons contribute money, property, or industry to a common fund with the intention of dividing profits among themselves.

Each relation creates specific obligations governed by both general principles and special Civil Code provisions.

XLIII. Proof of Obligations

A party who alleges the existence of an obligation generally bears the burden of proving it.

Proof may consist of:

written contracts;
receipts;
invoices;
promissory notes;
correspondence;
admissions;
witness testimony;
conduct of the parties;
electronic records, where admissible.

Certain agreements must comply with formal requirements for enforceability or validity. For example, some contracts must be in writing under the Statute of Frauds to be enforceable.

XLIV. Prescription of Actions

Obligations may become unenforceable by lapse of time through prescription.

Prescription does not necessarily erase the moral or natural duty, but it may bar court action.

The prescriptive period depends on the nature of the obligation and the applicable law. Written contracts, oral contracts, injury to rights, quasi-delicts, and other causes of action may have different periods.

Prescription encourages diligence and protects parties from stale claims.

XLV. Essential Doctrinal Distinctions

Obligation vs. Contract

An obligation is a juridical necessity to give, to do, or not to do. A contract is only one source of obligations.

All contracts create obligations, but not all obligations arise from contracts.

Obligation vs. Right

A right belongs to the creditor. An obligation burdens the debtor. They are correlative: the debtor’s obligation corresponds to the creditor’s right.

Damage vs. Injury

Injury refers to the legal wrong or violation of a right. Damage refers to the loss, hurt, or harm suffered. Damages refer to monetary compensation.

Fault vs. Fraud

Fault is negligence or lack of due care. Fraud is intentional evasion or deception.

Civil Liability from Crime vs. Quasi-Delict

Civil liability from crime arises from a criminal offense. Quasi-delict arises from negligence independent of a contract and may exist even if no crime is prosecuted or proven.

XLVI. Practical Importance of the Law on Obligations

The law on obligations is central to Philippine private law because it determines:

When a person is legally bound;
What must be performed;
When performance may be demanded;
What happens in case of breach;
What defenses may be raised;
What remedies are available;
When liability is extinguished.

It affects everyday transactions: borrowing money, buying goods, renting property, hiring contractors, employing workers, transporting passengers, entrusting property, entering business arrangements, and settling disputes.

XLVII. Conclusion

Under Philippine civil law, an obligation is a juridical necessity to give, to do, or not to do. Its essential elements are the active subject, passive subject, prestation, and juridical tie. Without these elements, there is no enforceable civil obligation.

Obligations may arise from law, contracts, quasi-contracts, crimes, and quasi-delicts. They may involve giving, doing, or not doing; may be pure, conditional, or subject to a period; may be joint or solidary; divisible or indivisible; alternative or facultative; and may include penal clauses.

The Civil Code’s rules on obligations balance autonomy, fairness, accountability, and social order. They protect creditors by enforcing lawful demands, but they also protect debtors by recognizing defenses such as impossibility, payment, loss without fault, prescription, and extinguishment. At its core, the Philippine law of obligations gives legal structure to private relations and ensures that rights and duties are respected in accordance with justice, good faith, and law.
