I. Introduction

An obligation is a juridical necessity to give, to do, or not to do. Under Philippine civil law, obligations arise from law, contracts, quasi-contracts, delicts, and quasi-delicts. Once an obligation exists, the debtor is bound to perform, and the creditor has the right to demand performance.

But obligations do not last forever. The Civil Code recognizes several ways by which obligations may be extinguished. Extinguishment means that the juridical tie between creditor and debtor is ended, either because the obligation has been fulfilled, replaced, waived, lost, merged, compensated, annulled, rescinded, prescribed, or otherwise terminated by law.

The primary modes of extinguishing obligations under Philippine civil law are:

payment or performance;
loss of the thing due;
condonation or remission of the debt;
confusion or merger of rights;
compensation;
novation;
annulment;
rescission;
fulfillment of a resolutory condition;
prescription;
other causes provided by law.

These modes are important in contracts, loans, sales, leases, services, damages, family property disputes, business transactions, bank obligations, real estate dealings, employment-related civil claims, and collection cases. Understanding them helps determine whether a creditor may still collect, whether a debtor may refuse payment, and whether an obligation has legally ended.

II. Basic Concept of Extinguishment of Obligations

An obligation creates a legal relation between two parties:

the creditor or obligee, who has the right to demand;
the debtor or obligor, who has the duty to perform.

When the obligation is extinguished, the creditor’s right to demand and the debtor’s duty to perform are terminated, either fully or partially.

Extinguishment may be:

1. Total

The entire obligation is ended.

Example: A borrower fully pays the loan and interest.

2. Partial

Only part of the obligation is extinguished.

Example: A borrower pays ₱70,000 out of a ₱100,000 loan. The obligation remains as to ₱30,000, unless there is waiver, compromise, or another extinguishing mode.

3. Voluntary

The parties intentionally end the obligation.

Example: The creditor condones the debt.

4. Involuntary

The obligation ends by operation of law or circumstances.

Example: A specific thing due is lost without the debtor’s fault before delay.

5. Principal or Accessory

Extinguishment of the principal obligation generally extinguishes accessory obligations, such as guaranty, pledge, or mortgage, unless the law or agreement provides otherwise. However, extinguishment of an accessory obligation does not necessarily extinguish the principal debt.

III. Payment or Performance

A. Concept

Payment or performance is the normal and most common mode of extinguishing obligations. It means the delivery of money, delivery of a thing, or rendering of service that fulfills the obligation.

Payment is not limited to money. In civil law, “payment” includes complete performance of whatever is due.

Examples:

A borrower pays the loan.
A seller delivers the car sold.
A contractor completes the construction.
A tenant pays rent.
A debtor returns a borrowed item.
A person obligated not to build a wall complies by not building it.

B. Requisites of Valid Payment

For payment to extinguish the obligation, it must generally comply with the obligation’s terms. The creditor is entitled to receive what was agreed upon, not something else, unless the creditor consents.

Valid payment generally requires:

the person paying has authority or capacity;
the person receiving payment is the creditor or authorized representative;
the thing or service paid is the prestation due;
payment is complete, unless partial payment is accepted;
payment is made at the proper time and place;
payment complies with contract and law.

C. Identity of Prestation

The debtor must deliver or perform the very thing due.

If the obligation is to deliver a specific car, the debtor cannot substitute a different car without the creditor’s consent.

If the obligation is to pay money, the debtor generally cannot force the creditor to accept goods instead.

D. Integrity or Completeness

Payment must be complete to extinguish the obligation fully. The creditor cannot generally be compelled to accept partial payment unless there is agreement, law, or special circumstances.

Example: If the debt is ₱100,000, payment of ₱60,000 does not extinguish the whole debt unless the creditor agrees to accept it as full settlement.

E. Payment by a Third Person

A third person may pay the obligation, whether or not the debtor knows, subject to rules on reimbursement and subrogation.

Situations include:

payment by guarantor;
payment by co-debtor;
payment by relative;
payment by insurer;
payment by interested third person;
payment by stranger.

If the third person pays with the debtor’s consent, they may generally recover what was paid and may be subrogated in the creditor’s rights if proper.

If the third person pays without the debtor’s knowledge or against the debtor’s will, reimbursement rights may be limited depending on benefit to the debtor and applicable rules.

F. Payment to the Proper Person

Payment must be made to the creditor, successor, assignee, agent, or person authorized to receive it.

Payment to the wrong person may not extinguish the obligation unless:

the payment benefited the creditor;
the creditor ratified the payment;
the recipient had apparent authority under circumstances binding the creditor;
the law treats the payment as valid;
payment was made in good faith to a person in possession of the credit under circumstances recognized by law.

Example: If a debtor pays a fake collector who has no authority from the creditor, the debtor may still remain liable to the real creditor.

G. Payment to an Incapacitated Creditor

Payment to an incapacitated person may be valid only to the extent that the payment benefited that person, or if made to a legal representative.

Example: Payment to a minor creditor may not fully extinguish the obligation unless the minor actually benefited or the payment was received by the guardian or proper representative.

H. Application of Payments

When a debtor owes several debts of the same kind to the same creditor, and makes a payment insufficient to cover all, the payment must be applied to a particular debt.

Application may be made:

by the debtor at the time of payment;
by the creditor if the debtor accepts the receipt applying it;
by law, if neither party validly applies it.

If a debt earns interest, payment is generally applied first to interest before principal unless otherwise agreed or legally allowed.

I. Dation in Payment

Dation in payment, or dación en pago, occurs when the debtor delivers property to the creditor in satisfaction of a monetary debt, and the creditor accepts it.

Example: A debtor owes ₱1,000,000 and transfers a vehicle to the creditor as full payment.

Dation is similar to a sale because ownership of property is transferred to satisfy a debt. The obligation is extinguished to the extent agreed upon. If the creditor accepts the property as full settlement, the whole debt is extinguished. If accepted only as partial settlement, the balance remains.

J. Payment by Cession

Payment by cession occurs when a debtor assigns or abandons all or some properties to creditors so that the creditors may sell them and apply the proceeds to debts.

Unlike dation, ownership is not necessarily transferred immediately as payment. Rather, creditors are given authority to sell and apply proceeds. Unless otherwise agreed, cession generally extinguishes obligations only up to the net proceeds obtained.

This is relevant when a debtor is insolvent and multiple creditors are involved.

K. Tender of Payment and Consignation

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

Tender of Payment

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

Consignation

Consignation is the judicial deposit of the thing or amount due when the creditor refuses without just cause, is absent, incapacitated, unknown, or when multiple persons claim the right to collect.

Proper consignation can extinguish the obligation even without the creditor’s acceptance, but strict requirements must be followed.

Common situations include:

landlord refuses rent to create default;
creditor refuses full payment;
several heirs claim the right to collect;
creditor is unknown or absent;
title documents prevent safe payment.

Improper consignation may fail to extinguish the debt.

L. Substantial Performance

In obligations to do, substantial performance in good faith may allow recovery as though there had been strict and complete fulfillment, less damages suffered by the creditor.

Example: A contractor substantially completes a building, with minor defects. The owner may not refuse all payment, but may deduct damages or cost of correction.

M. Incomplete or Irregular Performance Accepted by Creditor

If the creditor accepts incomplete or irregular performance with knowledge of defects and without protest, the obligation may be considered extinguished or the creditor may lose the right to complain, depending on the facts.

Example: A buyer accepts delivery of slightly late goods without reservation and pays the price. Later claims may be limited.

IV. Loss of the Thing Due

A. Concept

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

A determinate thing is a specific, individualized object.

Example: “The 2020 Toyota Vios with plate number ABC 1234” is determinate.

If that specific car is destroyed by accidental fire without the debtor’s fault before delivery is due and before delay, the obligation to deliver it may be extinguished.

B. Loss Must Be Without Debtor’s Fault

If the thing is lost through the debtor’s fault, negligence, fraud, or delay, the obligation is not simply extinguished. The debtor may be liable for damages.

Example: Seller agrees to deliver a specific painting tomorrow. Tonight, the seller negligently leaves it in the rain and it is destroyed. The seller is liable.

C. Loss Must Occur Before Delay

If the debtor is already in delay, loss of the thing generally does not extinguish liability. The debtor may still be responsible even if the loss is due to fortuitous event, subject to exceptions.

Example: Seller should have delivered the car on March 1 but failed. On March 5, a flood destroys the car. The seller may remain liable because of delay.

D. Generic Things Do Not Perish

The rule is often expressed as: genus never perishes.

If the obligation is to deliver a generic thing, such as “100 sacks of rice,” the debtor cannot usually avoid liability by saying their own stock was destroyed. They can obtain rice elsewhere.

If the obligation is limited generic, the result may depend on the circumstances.

Example: “100 sacks of rice from my specific warehouse” may be affected if the entire warehouse stock is destroyed without fault.

E. Legal Impossibility and Physical Impossibility

An obligation to do may be extinguished if performance becomes legally or physically impossible without the debtor’s fault.

Examples:

A singer contracted for a concert loses their voice due to serious illness.
A law prohibits the specific contracted act after the contract is made.
A unique venue is destroyed before the event without fault.

However, impossibility must be real, not mere inconvenience or increased cost.

F. Partial Loss

If only part of the thing is lost, the court may determine whether the loss is so important that the obligation should be extinguished.

Example: A specific machine is damaged but repairable. The debtor may not be fully released, but liability may change.

G. Presumption of Fault

If the thing is lost while in the debtor’s possession, there may be a presumption that the loss was due to the debtor’s fault, unless proven otherwise.

The debtor must often show that the loss was due to fortuitous event and that they exercised due diligence.

H. Fortuitous Event

A fortuitous event is an event that could not be foreseen, or though foreseen, was inevitable. Examples may include natural disasters, accidental fire, war, or sudden legal prohibition, depending on circumstances.

To avoid liability, the debtor must generally prove:

the event was independent of human will;
it was unforeseeable or unavoidable;
it rendered performance impossible;
the debtor was free from fault or delay;
the debtor did not assume the risk.

Contracts may allocate risk differently.

V. Condonation or Remission of the Debt

A. Concept

Condonation or remission is the gratuitous abandonment by the creditor of their right to collect. It is essentially forgiveness of the debt.

Example: A creditor tells the debtor in writing: “I forgive your ₱50,000 debt. You no longer need to pay.”

Condonation extinguishes the obligation to the extent forgiven.

B. Nature of Condonation

Condonation is an act of liberality. Because it is similar to donation, it may be subject to rules on donations, including acceptance and formal requirements depending on the amount or property involved.

C. Express Condonation

Express condonation is clearly stated, orally or in writing, subject to legal formalities.

Example: A signed waiver of debt.

For larger obligations, written documentation is advisable.

D. Implied Condonation

Condonation may be implied from acts showing the creditor’s intent to forgive.

Examples:

voluntary delivery of the private document evidencing the debt to the debtor;
destruction or cancellation of debt document by the creditor under circumstances showing intent to forgive;
return of promissory note without reservation.

However, implied condonation must be clear. Mere delay in collection is not automatically condonation.

E. Condonation Must Be Accepted

Because condonation is similar to donation, acceptance by the debtor may be required. Acceptance may be express or implied.

Example: If the debtor receives the creditor’s written waiver and relies on it, acceptance may be inferred.

F. Partial Condonation

The creditor may forgive only part of the debt.

Example: A creditor waives interest and penalties but requires payment of principal.

The obligation is extinguished only as to the waived portion.

G. Condonation of Principal and Accessory Obligations

Condonation of the principal debt generally extinguishes accessory obligations, such as interest, pledge, mortgage, or guaranty.

Condonation of an accessory obligation does not necessarily extinguish the principal debt.

Example: A creditor waives the penalty charge but not the loan principal.

H. Condonation Must Not Prejudice Third Persons

A creditor cannot use condonation to prejudice rights of third persons in ways prohibited by law.

Example: If the creditor’s waiver is fraudulent against their own creditors, remedies may exist.

I. Difference From Compromise

Condonation is gratuitous. Compromise involves mutual concessions.

Example:

Condonation: creditor forgives the whole debt without receiving anything.
Compromise: creditor accepts ₱60,000 as full settlement of a ₱100,000 disputed claim.

VI. Confusion or Merger of Rights

A. Concept

Confusion or merger 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. B dies and A becomes B’s sole heir. A becomes both debtor and creditor of the same debt. The obligation may be extinguished by merger.

No person can owe themselves in the same legal capacity.

B. Requisites

Confusion generally requires:

the same person becomes creditor and debtor;
the merger occurs in the same obligation;
the merger occurs in the same legal capacity;
the obligation is not kept alive for reasons recognized by law.

C. Same Capacity Requirement

If the person is creditor in one capacity and debtor in another, confusion may not occur.

Example: A is personally indebted to a corporation. A later becomes president of the corporation. There is no merger because the corporation is a separate juridical person.

Example: A is debtor personally, and creditor as trustee for another. There may be no merger because capacities differ.

D. Merger in Joint Obligations

In joint obligations, confusion involving one debtor or creditor generally extinguishes only the corresponding share.

Example: A and B jointly owe C ₱100,000. C later inherits A’s share. The obligation may be extinguished only as to A’s share, not B’s.

E. Merger in Solidary Obligations

In solidary obligations, effects may differ because each solidary debtor may be liable for the whole obligation, subject to reimbursement rights. If confusion occurs between the creditor and one solidary debtor, the obligation may be affected, but internal reimbursement issues may remain.

F. Merger and Guaranty

If creditor and principal debtor merge, the guaranty is generally extinguished because the principal obligation is extinguished.

If creditor and guarantor merge, the principal obligation may remain, because the debtor and creditor are still distinct.

VII. Compensation

A. Concept

Compensation occurs when two persons are reciprocally debtors and creditors of each other, and their debts are extinguished to the concurrent amount.

Example: A owes B ₱100,000. B owes A ₱70,000. If legal compensation applies, A’s debt is reduced to ₱30,000.

Compensation is a practical way of avoiding useless exchange of payments.

B. Kinds of Compensation

Compensation may be:

legal — by operation of law;
voluntary or conventional — by agreement of parties;
judicial — declared by court;
facultative — available only to one party who may choose to invoke it.

C. Requisites of Legal Compensation

Legal compensation generally requires:

each party is a principal creditor and principal debtor of the other;
both debts consist of money, or consumable things of the same kind and quality;
both debts are due;
both debts are liquidated and demandable;
neither debt is subject to retention or controversy by third persons communicated in due time.

If all requisites are present, compensation may occur by operation of law, even without the parties expressly agreeing.

D. Principal Debtor and Creditor Requirement

The parties must be bound principally. A guarantor cannot automatically compensate the creditor’s debt to the principal debtor unless legal conditions allow.

Example: A owes Bank ₱100,000. Bank owes A ₱50,000 refund. Compensation may be possible.

But if A is merely guarantor for B’s debt to Bank, compensation may not be automatic in the same way.

E. Debts Must Be Due, Liquidated, and Demandable

A debt is liquidated when its amount is determined or readily determinable.

A debt is demandable when it can be legally enforced.

Example: A claim for unliquidated damages may not be legally compensated against a clear loan unless determined by agreement or judgment.

F. No Compensation for Certain Obligations

Some obligations cannot be compensated because of public policy or legal rules.

Examples may include:

obligations arising from depositum in certain cases;
obligations of a depositary or bailee in commodatum;
support due by gratuitous title;
civil liability arising from certain wrongful acts, depending on the nature and law;
claims where compensation is prohibited by law or agreement.

G. Compensation and Assignment of Credit

If a creditor assigns a credit to a third person, compensation issues may arise depending on whether the debtor consented, knew, or had existing claims before notice of assignment.

Example: If A owes B, and B assigns the credit to C, A may or may not assert compensation against C depending on timing and circumstances.

H. Partial Compensation

If debts are unequal, compensation extinguishes both debts to the concurrent amount.

Example: A owes B ₱500,000. B owes A ₱200,000. After compensation, A owes B ₱300,000.

I. Voluntary Compensation

Even if legal requisites are lacking, parties may agree to compensate obligations.

Example: A’s debt is due, but B’s debt is not yet due. B may agree to offset them anyway.

J. Compensation Versus Payment

Payment requires actual performance. Compensation extinguishes obligations by offsetting reciprocal debts.

VIII. Novation

A. Concept

Novation is the extinguishment of an obligation by substituting or changing it with a new obligation. It may change the object, principal conditions, debtor, creditor, or legal relation.

Example: A owes B ₱100,000 payable in cash. A, B, and C agree that C will replace A as debtor. If intended as novation, A may be released and C becomes debtor.

Novation is both an extinguishing and creating mode: it extinguishes the old obligation and creates a new one.

B. Novation Is Never Presumed

Novation must be clearly shown. It may be express, or implied only when the old and new obligations are incompatible in every point.

Mere changes in payment schedule, additional security, or partial modifications may not constitute novation unless clearly intended.

C. Requisites of Novation

Novation generally requires:

a previous valid obligation;
agreement of all parties concerned to the new obligation;
extinguishment of the old obligation;
validity of the new obligation.

If the old obligation is void, there is generally nothing to novate, unless the parties validly create a new obligation independently. If the new obligation is void, novation may fail.

D. Objective or Real Novation

Objective novation changes the object or principal conditions of the obligation.

Examples:

changing obligation from delivering a car to paying money;
replacing a loan with sale of property as full settlement;
changing essential terms so substantially that the old obligation is extinguished.

Minor changes are not necessarily novation.

E. Subjective or Personal Novation

Subjective novation changes the parties.

It may occur by:

substitution of debtor;
subrogation of creditor.

F. Substitution of Debtor

Substitution of debtor may be:

Expromision

A third person takes the debtor’s place without the debtor’s initiative, but with creditor consent.

Example: C agrees with B to pay A’s debt, and B releases A.

Delegacion

The debtor offers a new debtor to the creditor, and the creditor accepts.

Example: A asks B to accept C as new debtor. B agrees and releases A.

Creditor consent is essential because the creditor cannot be forced to accept a new debtor.

G. Effect of New Debtor’s Insolvency

If the new debtor becomes insolvent, whether the old debtor remains liable depends on the type of substitution, debtor’s knowledge, and circumstances.

Generally, if the creditor accepted the new debtor and released the old debtor, the old debtor is not liable for the new debtor’s insolvency unless the old debtor acted in bad faith or the insolvency was already existing and known under conditions recognized by law.

H. Subrogation of Creditor

Subrogation transfers the creditor’s rights to another person. It may be legal or conventional.

Example: A guarantor pays the creditor and is subrogated to the creditor’s rights against the principal debtor.

Subrogation allows the new creditor to enforce the rights, securities, and remedies of the original creditor, subject to law.

I. Mixed Novation

Mixed novation changes both object/conditions and parties.

Example: A debtor is substituted, the amount is restructured, and collateral is changed.

J. Novation and Accessory Obligations

When the principal obligation is extinguished by novation, accessory obligations may also be extinguished unless reserved or unless third persons benefited and consented.

Example: If a loan is novated and the guarantor did not consent to continue the guaranty, the guarantor may be released.

K. Novation Versus Modification

Not every modification is novation.

Examples that may not automatically be novation:

extension of payment period;
change in interest rate;
partial payment agreement;
additional collateral;
restructuring without express release;
acceptance of installment payments;
issuance of a new promissory note as evidence of old debt.

The key question is whether the parties intended to extinguish the old obligation and replace it with a new one.

L. Novation in Loan Restructuring

Loan restructuring often raises novation issues. A borrower may argue that the old loan was novated, while the lender may argue it was merely restructured.

To determine novation, examine:

wording of restructuring agreement;
whether old debt was expressly cancelled;
whether new obligation is incompatible with old one;
whether securities were released or retained;
whether guarantors consented;
whether old promissory notes were cancelled;
whether parties reserved rights under old agreement.

IX. Annulment

A. Concept

Annulment is a mode by which a voidable contract is set aside. If the obligation arises from a voidable contract and the contract is annulled, the obligation may be extinguished.

Voidable contracts are valid and binding until annulled.

B. Grounds for Annulment

Common grounds include:

incapacity of a party;
vitiated consent by mistake;
violence;
intimidation;
undue influence;
fraud.

If annulled, the parties may be restored to their original positions through mutual restitution, subject to legal rules.

C. Effect on Obligations

If a contract of sale is annulled, the buyer may return the property and the seller may return the price. The obligation under the contract is extinguished, but restitution obligations may arise.

Example: A person was induced by fraud to sign a contract. If annulled, the contractual obligation may cease, but the parties must return what they received.

D. Annulment Is Not Automatic

A voidable contract remains effective until a proper action for annulment is brought and granted, or until the contract is ratified.

A debtor cannot simply ignore a voidable obligation without proper legal basis.

E. Ratification

Ratification cleanses the defect of a voidable contract. Once ratified, the party entitled to annulment may lose the right to annul.

Example: A person who discovers fraud but continues accepting benefits and confirms the contract may be deemed to have ratified, depending on facts.

X. Rescission

A. Concept

Rescission is a remedy that cancels a valid contract because of economic prejudice, lesion, or breach under circumstances recognized by law.

In obligations, rescission may extinguish the obligation arising from the contract and require mutual restitution.

B. Rescissible Contracts

Certain contracts are rescissible because they cause damage or prejudice, such as:

contracts entered into by guardians when wards suffer lesion beyond the legal threshold;
contracts entered into in representation of absentees with legal lesion;
contracts in fraud of creditors;
contracts involving things under litigation without proper authority;
other contracts declared rescissible by law.

C. Rescission for Breach in Reciprocal Obligations

In reciprocal obligations, one party may seek rescission if the other substantially fails to comply with what is incumbent upon them.

Example: Buyer fails to pay the price; seller may seek rescission. Seller fails to deliver; buyer may seek rescission.

The injured party may choose between fulfillment and rescission, with damages in either case, subject to law.

D. Mutual Restitution

Rescission generally requires parties to return what they received.

Example: If a sale is rescinded, the buyer returns the property, and the seller returns the price.

If restitution is impossible, damages may be awarded.

E. Rescission Is Subsidiary in Some Cases

For certain rescissible contracts, rescission may be subsidiary, meaning it may be used only when the injured party has no other legal means to obtain reparation.

F. Rescission Versus Annulment

Annulment deals with defective consent or incapacity in voidable contracts.

Rescission deals with valid contracts that are set aside because of injury, fraud of creditors, or substantial breach.

G. Rescission Versus Resolution

In Philippine usage, rescission sometimes refers broadly to resolution of reciprocal obligations due to breach. Strictly, the Civil Code uses rescission in more than one context, so the facts and legal basis must be clear.

XI. Fulfillment of a Resolutory Condition

A. Concept

A resolutory condition is a future and uncertain event upon which an existing obligation is extinguished.

Example: A allows B to use a commercial space until the building is sold. The sale of the building is a resolutory condition. When the building is sold, B’s right to use may end, depending on agreement and law.

B. Suspensive Versus Resolutory Condition

A suspensive condition gives rise to an obligation only upon fulfillment of the condition.

A resolutory condition extinguishes an existing obligation upon fulfillment of the condition.

Example:

Suspensive: “I will pay you if I win the case.” The obligation arises only if the case is won.
Resolutory: “You may occupy the unit until I return from abroad.” The obligation ends when the person returns.

C. Effect of Fulfillment

When the resolutory condition occurs, the obligation is extinguished. Depending on the contract, there may be restitution or liquidation of benefits already received.

D. Non-Occurrence

If the resolutory condition never happens, the obligation continues according to its terms.

E. Prevention by a Party

If a party wrongfully prevents or causes the condition to occur, legal consequences may arise. Courts may treat the condition as fulfilled or not fulfilled depending on justice and law.

XII. Prescription

A. Concept

Prescription extinguishes the legal right to enforce an obligation after the lapse of time provided by law.

It is based on public policy: claims should be pursued within a reasonable period, and parties should not be exposed to stale demands forever.

B. Extinctive Prescription

Extinctive prescription bars an action after the legal period has passed.

Example: A creditor waits too long to sue on a written contract. The debtor may invoke prescription as a defense.

C. Prescription Does Not Always Erase the Moral Debt

Prescription may bar judicial enforcement but does not necessarily erase the natural or moral obligation. Voluntary payment of a prescribed debt may not be recoverable in certain cases because it may be treated as fulfillment of a natural obligation.

D. Period Depends on Type of Action

The prescriptive period depends on the nature of the obligation or action, such as:

written contract;
oral contract;
injury to rights;
quasi-delict;
mortgage action;
judgment;
collection of sum;
recovery of property;
fraud-related actions.

The exact period must be determined based on the claim.

E. Interruption of Prescription

Prescription may be interrupted by:

filing of action in court;
written extrajudicial demand by creditor;
written acknowledgment of debt by debtor;
other acts recognized by law.

Interruption causes the period to restart or affects computation depending on the situation.

F. Waiver of Prescription

A debtor may waive prescription after it has accrued, expressly or impliedly, such as by acknowledging the debt or promising payment.

However, waiver of future prescription may be restricted by law or public policy.

G. Prescription Must Be Invoked

Prescription is generally a defense. A debtor should raise it properly. Failure to plead prescription may result in waiver, depending on procedural rules.

H. Prescription and Continuing Obligations

For installment obligations, each installment may have its own due date and prescriptive period.

Example: Monthly rentals may prescribe separately based on each due date.

I. Prescription in Family and Property Contexts

Prescription can be complicated in co-ownership, trusts, inheritance, fraud, possession, and registered land. Possession by one co-owner may not immediately prescribe against others unless clear repudiation occurs. Registered land may also be subject to special rules.

XIII. Other Causes of Extinguishment

The Civil Code recognizes that obligations may also be extinguished by other causes provided by law.

These include:

compromise;
mutual desistance;
death in personal obligations;
expiration of term;
resolutory period;
impossibility of performance;
release by judgment;
insolvency or rehabilitation effects, where applicable;
fulfillment of purpose;
cancellation by agreement;
termination under contract;
merger under special laws;
foreclosure effects in certain cases;
statutory discharge;
waiver;
satisfaction of judgment.

Each must be examined according to its legal basis.

XIV. Compromise

A. Concept

A compromise is a contract where parties make reciprocal concessions to avoid litigation or end an existing dispute.

Example: Creditor claims ₱500,000. Debtor disputes the amount. They agree that debtor will pay ₱300,000 as full settlement. Upon payment, the obligation is extinguished according to the compromise.

B. Effect of Compromise

A valid compromise has the effect of law between the parties. It may extinguish the original claim and replace it with the compromise obligation.

If the compromise is breached, the injured party may enforce the compromise or seek appropriate remedies.

C. Compromise Versus Condonation

Compromise involves mutual concessions. Condonation is gratuitous forgiveness.

D. Compromise in Court

A court-approved compromise may become a judgment upon compromise. Violation may be enforced like a judgment.

XV. Mutual Desistance or Mutual Withdrawal

Parties may mutually agree to cancel or terminate a contract. This is sometimes called mutual desistance.

Example: Buyer and seller agree to cancel a sale before delivery and return the down payment.

Mutual desistance extinguishes obligations according to the terms agreed. It may include refund, waiver, return of goods, or settlement of expenses.

XVI. Death of a Party

A. General Rule

Death does not automatically extinguish obligations. Many obligations pass to the estate of the deceased.

Example: A person’s unpaid loan may be claimed against the estate.

B. Personal Obligations

Obligations that are purely personal may be extinguished by death.

Examples:

contract to paint a portrait by a specific artist;
personal service contract dependent on the unique skill of the debtor;
obligation based on personal trust;
agency in certain cases;
obligations where death makes performance impossible or legally terminated.

C. Estate Liability

If the obligation is monetary or property-related, it usually survives and may be enforceable against the estate, subject to estate settlement rules.

XVII. Expiration of Term

If an obligation or contract has a fixed term, it may end upon expiration of that term.

Example: A lease for one year expires at the end of the agreed period, unless renewed.

Expiration extinguishes future obligations, but accrued obligations remain.

Example: If rent for the last month is unpaid, expiration of lease does not erase that unpaid rent.

XVIII. Resolutory Period

A resolutory period is a day certain upon arrival of which the obligation is extinguished.

Example: “The lease shall end on December 31, 2026.”

Unlike a condition, a period is certain to arrive, though the exact date may sometimes be uncertain if tied to an event certain to happen.

XIX. Impossibility of Performance

Obligations to do may be extinguished when performance becomes impossible without debtor’s fault.

Examples:

the subject service becomes illegal;
the required act becomes physically impossible;
the unique object or condition necessary for performance disappears;
government prohibition prevents performance.

However, mere difficulty, increased expense, or inconvenience does not automatically extinguish the obligation.

XX. Waiver

Waiver is the intentional relinquishment of a known right.

It may extinguish an obligation or a claim if the creditor clearly waives it.

Requisites generally include:

existence of a right;
knowledge of the right;
intention to relinquish it.

Waiver must be clear. Courts do not lightly presume waiver.

Examples:

waiver of penalties;
waiver of interest;
waiver of right to demand strict delivery date;
waiver of right to collect part of a claim.

A waiver contrary to law, public policy, or rights of third persons may be invalid.

XXI. Satisfaction of Judgment

If an obligation has been reduced to a court judgment, satisfaction of judgment extinguishes the judgment obligation.

Modes include:

payment;
levy and execution;
garnishment;
compromise;
release by judgment creditor;
court-approved satisfaction.

A judgment debtor should secure proof of satisfaction to prevent future enforcement.

XXII. Foreclosure and Extinguishment

Foreclosure may affect obligations secured by mortgage or pledge.

In some cases, foreclosure sale proceeds extinguish the debt to the amount realized. If proceeds are insufficient, a deficiency may or may not be recoverable depending on the law, type of security, and transaction.

For chattel mortgage, real estate mortgage, pledge, and other security arrangements, the effect of foreclosure must be examined carefully.

Foreclosure of security does not always automatically extinguish the entire debt unless proceeds fully satisfy it or the law bars deficiency recovery.

XXIII. Rescission, Cancellation, and Termination Clauses

Contracts often include termination clauses. These may extinguish obligations upon:

default;
notice;
expiration;
insolvency;
failure to obtain permits;
change of control;
breach of confidentiality;
non-payment;
convenience termination;
force majeure;
government prohibition.

The effect depends on contract wording and law.

A contractual cancellation clause cannot override mandatory legal protections.

Example: A real estate installment sale may be subject to statutory buyer protections even if the contract provides automatic forfeiture.

XXIV. Force Majeure Clauses

A force majeure clause may excuse or suspend performance when extraordinary events occur.

Depending on wording, it may:

extinguish the obligation;
suspend performance;
extend deadlines;
excuse damages;
allow termination;
require renegotiation.

Events may include natural disasters, war, government lockdown, epidemic, strikes, or other uncontrollable events, depending on contract terms.

Force majeure does not automatically apply. The party invoking it must prove the event and its effect on performance.

XXV. Unilateral Cancellation Is Usually Not Enough

A debtor or creditor cannot generally extinguish an obligation by simply declaring it cancelled, unless the law or contract allows unilateral termination.

Example: A borrower cannot say, “I cancel my loan,” and be free from payment.

Example: A buyer cannot cancel a sale and demand refund unless there is legal or contractual basis.

Unilateral termination clauses must be exercised in good faith and according to law.

XXVI. Extinguishment of Accessory Obligations

Accessory obligations depend on principal obligations. Examples include:

interest;
penalties;
guaranty;
suretyship;
pledge;
mortgage;
antichresis;
lien.

If the principal obligation is extinguished, accessory obligations generally follow.

Example: Full payment of a car loan should lead to release of chattel mortgage.

However, if only an accessory obligation is extinguished, the principal obligation may remain.

Example: Waiver of penalty does not necessarily waive the principal debt.

XXVII. Interest and Penalties

Interest and penalties may be extinguished by:

payment;
waiver;
condonation;
compromise;
prescription;
annulment or rescission of the principal obligation;
court reduction if unconscionable;
novation if clearly intended;
application of payments.

A creditor’s acceptance of principal without reservation may raise issues on whether interest or penalties were waived, depending on circumstances and receipts.

XXVIII. Payment Receipt and Extinguishment

A receipt is important evidence of payment. It may show:

amount paid;
date;
payer;
payee;
obligation covered;
whether payment is partial or full;
whether interest is included;
whether settlement is final;
whether reservation of rights exists.

A receipt stating “full payment” or “full settlement” may support extinguishment, but the full context matters.

Creditors should indicate if payment is partial. Debtors should demand clear receipts.

XXIX. Burden of Proving Extinguishment

The debtor who claims that an obligation has been extinguished generally has the burden of proving the extinguishing fact.

Examples:

If debtor claims payment, debtor should show receipts or proof of transfer.
If debtor claims condonation, debtor should show waiver.
If debtor claims compensation, debtor should prove reciprocal due and liquidated debts.
If debtor claims prescription, debtor should show lapse of required period.
If debtor claims novation, debtor should show clear intent to extinguish old obligation.

The creditor must prove the obligation. The debtor must prove extinguishment.

XXX. Effect of Invalid Payment

If payment is made improperly, it may not extinguish the obligation.

Examples:

payment to unauthorized person;
payment by check that later bounces;
payment with counterfeit money;
delivery of wrong item;
partial payment not accepted as full;
payment after creditor validly rescinded;
payment subject to unresolved conditions.

A debtor should ensure payment is made through authorized channels and properly documented.

XXXI. Payment by Check

Payment by check generally produces effect only when encashed or when impairment is due to creditor’s fault, depending on circumstances.

A check is not the same as cash unless accepted as such.

If the check bounces, the obligation is not extinguished and separate legal consequences may arise.

XXXII. Electronic Payments

Modern obligations are often paid through bank transfer, e-wallet, QR code, online banking, or payment gateways.

Electronic payment may extinguish the obligation if:

made to the correct account;
amount is correct;
payment is successfully completed;
creditor accepts or is legally bound by the channel;
proof of payment exists;
no reversal or fraud occurs.

Risks include:

wrong account transfer;
fake QR code;
unauthorized collector;
payment gateway delay;
reference number mismatch;
system error;
failure to indicate account number.

Debtors should keep screenshots, transaction reference numbers, confirmations, and receipts.

XXXIII. Payment to Collection Agencies

Payment to a collection agency extinguishes the obligation only if the agency is authorized to receive payment.

Debtors should verify:

collection agency authority;
official payment channel;
account name;
receipt;
updated statement of account;
creditor confirmation;
full settlement terms.

Payment to a fake collector may not bind the creditor.

XXXIV. Full Settlement Agreements

A full settlement agreement extinguishes the obligation according to its terms.

It should state:

original obligation;
settlement amount;
due date;
whether amount is full and final;
waiver of balance;
release of securities;
issuance of clearance;
effect of default;
parties’ signatures.

Without clear wording, disputes may arise over whether payment was partial or full.

XXXV. Quitclaims and Releases

A quitclaim or release may extinguish claims if voluntarily executed, supported by consideration where needed, and not contrary to law or public policy.

However, quitclaims may be challenged if obtained through:

fraud;
intimidation;
mistake;
undue influence;
gross inadequacy;
lack of understanding;
violation of statutory rights.

In employment, consumer, real estate, and family contexts, waivers may be scrutinized.

XXXVI. Extinguishment in Solidary Obligations

In solidary obligations, each debtor may be liable for the whole obligation, and each creditor may demand the whole, depending on the terms.

Modes of extinguishment can have special effects.

Payment

Payment by one solidary debtor extinguishes the obligation as to the creditor, but the paying debtor may seek reimbursement from co-debtors for their shares.

Condonation

Condonation of one debtor may affect others depending on whether the remission covers the whole obligation or only one debtor’s share.

Confusion

Merger between creditor and one solidary debtor may extinguish the obligation in relation to the creditor but internal adjustments may remain.

Compensation

Compensation involving one solidary debtor may benefit others, depending on circumstances and extent.

The internal relationship among solidary parties must be separately examined.

XXXVII. Extinguishment in Joint Obligations

In joint obligations, each debtor is liable only for their own share, and each creditor may demand only their share, unless solidarity is clearly provided by law or contract.

Extinguishment affecting one joint debtor generally affects only that debtor’s share.

Example: If A, B, and C jointly owe D ₱90,000, each owes ₱30,000. Payment by A of ₱30,000 extinguishes A’s share but not B’s or C’s.

XXXVIII. Divisible and Indivisible Obligations

Extinguishment may differ depending on whether the obligation is divisible or indivisible.

A divisible obligation can be partially performed and extinguished proportionately.

An indivisible obligation generally requires complete performance.

Example: Obligation to deliver a specific car is indivisible. Partial delivery of parts does not extinguish the obligation.

XXXIX. Alternative Obligations

In alternative obligations, several prestations are due, but performance of one extinguishes the obligation.

Example: Debtor must deliver either a laptop, a phone, or ₱50,000. Once the valid choice is made and performed, the obligation is extinguished.

If some prestations become impossible, rules on choice and fault determine what remains due.

XL. Facultative Obligations

In a facultative obligation, only one prestation is due, but the debtor may substitute another.

Example: Debtor owes a specific motorcycle but may instead pay ₱100,000. If the debtor validly substitutes and creditor receives payment, the obligation is extinguished.

Loss of the substitute before substitution generally does not affect the obligation. Loss of the principal prestation may extinguish or create liability depending on fault and timing.

XLI. Conditional Obligations

If an obligation is subject to condition, extinguishment depends on whether the condition is suspensive or resolutory.

If suspensive condition fails, the obligation never becomes effective.
If resolutory condition occurs, the obligation is extinguished.
If condition is fulfilled, rights and obligations follow the Civil Code rules.

XLII. Obligations With a Penal Clause

A penal clause imposes penalty in case of breach. Payment or performance may extinguish the principal obligation, but penalty issues depend on breach and agreement.

If the creditor accepts performance without reservation, the penalty may be waived depending on circumstances.

Courts may reduce penalties if they are iniquitous or unconscionable, or if there has been partial or irregular performance.

XLIII. Natural Obligations

A natural obligation is not enforceable by court action, but voluntary fulfillment produces legal effects.

Example: A prescribed debt may no longer be enforceable, but if the debtor voluntarily pays with knowledge, they may not recover the payment.

Natural obligations show that legal enforceability and moral obligation are not always the same.

XLIV. Nullity and Void Contracts

A void contract produces no valid obligation from the beginning. Strictly, there is no obligation to extinguish because the contract is inexistent or void.

However, parties may still have restitution obligations under unjust enrichment or related principles.

Examples of void contracts include those contrary to law, morals, public order, public policy, impossible services, or absolutely simulated contracts.

A void contract is different from a voidable contract, which is valid until annulled.

XLV. Unjust Enrichment and Extinguishment

If an obligation is extinguished or a contract fails, a party who retains benefits without basis may be liable under unjust enrichment or quasi-contract.

Example: A contract is rescinded. If one party keeps both the property and the price, restitution may be required.

Thus, extinguishment of one obligation may create another obligation to return benefits.

XLVI. Examples of Extinguishment in Common Philippine Transactions

A. Loan

A loan may be extinguished by full payment, condonation, compensation, novation, prescription, compromise, or discharge under applicable proceedings.

B. Sale

A sale obligation may be extinguished by delivery and payment, rescission, annulment, loss of determinate thing, mutual cancellation, or prescription of action.

C. Lease

Lease obligations may be extinguished by expiration of term, payment of rent, rescission for breach, loss of leased property, merger if lessor and lessee become same person, or mutual termination.

D. Construction Contract

Obligations may be extinguished by completion, acceptance, payment, rescission for breach, impossibility, compromise, or substantial performance with deduction.

E. Employment-Related Civil Obligations

Certain monetary obligations may be extinguished by payment, settlement, quitclaim, prescription, or judgment, subject to labor protections.

F. Real Estate Installment Sale

Obligations may be extinguished by full payment, cancellation under contract and law, rescission, mutual cancellation, foreclosure if mortgage-based, or statutory refund processes.

G. Vehicle Financing

Obligations may be extinguished by full payment, loan restructuring novation if clearly intended, foreclosure sale to the extent of proceeds, compromise, or prescription. Chattel mortgage should be released after full payment.

XLVII. Practical Checklist for Debtors

A debtor who claims extinguishment should keep:

official receipts;
bank transfer confirmations;
settlement agreement;
release or waiver;
certificate of full payment;
return receipt;
proof of delivery;
creditor acknowledgment;
statement of account showing zero balance;
cancellation of mortgage or lien;
court satisfaction of judgment;
written compromise;
proof of prescription if applicable.

Do not rely only on verbal assurances.

XLVIII. Practical Checklist for Creditors

A creditor should:

issue accurate receipts;
state whether payment is partial or full;
reserve rights if accepting partial payment;
document interest and penalties;
keep demand letters;
avoid unintentionally waiving rights;
respond carefully to proposed settlement;
verify if compensation is being claimed;
avoid delay that may lead to prescription;
preserve contracts and statements of account.

A creditor who accepts payment without reservation may later face arguments of waiver or full settlement.

XLIX. Common Mistakes

Common mistakes include:

assuming partial payment extinguishes the whole debt;
paying the wrong person;
failing to get receipts;
confusing restructuring with novation;
relying on oral condonation;
ignoring prescription periods;
assuming full loan payment automatically cancels mortgage records;
believing a bounced check is payment;
failing to reserve rights when accepting late or partial payment;
treating every contract cancellation as rescission;
forgetting accessory obligations;
assuming death always extinguishes debts;
failing to document compromise.

L. Frequently Asked Questions

1. What is the most common way obligations are extinguished?

Payment or performance is the most common mode.

2. Does partial payment extinguish an obligation?

Only to the extent paid, unless the creditor agrees to accept it as full settlement.

3. Can a creditor refuse partial payment?

Generally yes, unless the contract, law, or circumstances require acceptance.

4. Does a check count as payment?

Usually only when encashed or when the creditor’s fault prevents encashment. A bounced check does not extinguish the debt.

5. Can a debt be forgiven orally?

Possibly in some situations, but written proof is strongly advisable. Some forms of condonation may require formalities.

6. What is compensation?

It is offsetting reciprocal debts between two persons who are mutually creditors and debtors of each other.

7. What is novation?

It is replacing an old obligation with a new one, clearly extinguishing the old obligation.

8. Is loan restructuring automatically novation?

No. Novation is not presumed. Clear intent to extinguish the old obligation must be shown.

9. Does death extinguish debts?

Not usually. Monetary debts may be claimed against the estate. Purely personal obligations may be extinguished by death.

10. Does prescription erase a debt?

It may bar judicial enforcement, but voluntary payment of a prescribed debt may still have legal effect.

11. Does full payment of a car loan automatically remove chattel mortgage?

No. Release and cancellation documents must be processed with the proper offices.

12. Can an obligation be extinguished by impossibility?

Yes, if performance becomes legally or physically impossible without the debtor’s fault, subject to legal rules.

13. Can the parties cancel a contract by agreement?

Yes. Mutual desistance or mutual cancellation may extinguish obligations according to their agreement.

14. Does cancellation always require court action?

Not always. Some obligations may be cancelled by agreement or valid contractual termination. But rescission, annulment, or disputed cancellation may require court action.

15. Who must prove payment?

The debtor who claims payment generally must prove it.

LI. Key Takeaways

The main modes of extinguishing obligations under Philippine civil law are payment or performance, loss of the thing due, condonation, confusion, compensation, novation, annulment, rescission, fulfillment of a resolutory condition, and prescription.

Payment is the normal mode, but it must be complete and made to the proper person. Loss of a determinate thing may extinguish the obligation only if the debtor is without fault and not in delay. Condonation requires clear forgiveness. Confusion occurs when creditor and debtor become the same person. Compensation offsets reciprocal debts. Novation replaces the old obligation with a new one and is never presumed. Annulment and rescission may extinguish obligations but often require restitution. Prescription bars stale actions after the lapse of time.

The practical rule is simple: an obligation is not extinguished merely because a party says it is. There must be a legally recognized cause and evidence supporting it.

LII. Conclusion

Modes of extinguishing obligations are central to Philippine civil law because they determine when legal duties end and when demands may no longer be enforced. In everyday life, these rules govern loans, sales, leases, services, family transactions, damages, business dealings, bank obligations, and property disputes.

The safest approach is documentation. Debtors should keep proof of payment, release, waiver, settlement, or cancellation. Creditors should issue clear receipts, reserve rights when appropriate, and act before prescription. Both parties should understand that partial performance, informal promises, and verbal arrangements often create disputes.

In Philippine civil law, obligations may arise in many ways, but they are extinguished only through legally recognized modes. Knowing these modes helps parties avoid unnecessary litigation, protect their rights, and determine when an obligation has truly ended.
