I. Introduction

In Philippine civil law, an obligation is a juridical necessity to give, to do, or not to do. Once an obligation is validly created, the law expects performance. However, obligations do not exist forever. They may be terminated, discharged, or extinguished by causes recognized under law.

The principal provision is Article 1231 of the Civil Code of the Philippines, which states that obligations are extinguished:

By payment or performance;
By the loss of the thing due;
By the condonation or remission of the debt;
By the confusion or merger of the rights of creditor and debtor;
By compensation;
By novation.

The same article adds that obligations may also be extinguished by annulment, rescission, fulfillment of a resolutory condition, prescription, and other causes governed elsewhere in the Civil Code.

These modes are not merely technical rules. They determine whether a debtor remains liable, whether a creditor may still sue, whether security rights survive, and whether accessory obligations such as interest, penalties, pledges, mortgages, or guaranties are also discharged.

II. Payment or Performance

A. Concept

Payment does not only mean the delivery of money. Under Philippine law, payment means the fulfillment of the prestation due. If the obligation is to give money, payment is monetary. If the obligation is to deliver a thing, payment is delivery. If the obligation is to do or not to do something, payment means performance or faithful observance.

Payment is the most common and natural mode of extinguishing obligations.

B. Requisites of Valid Payment

For payment to extinguish an obligation, the following must generally concur:

There must be an existing obligation.
The person paying must have capacity and authority.
Payment must be made to the proper person.
The thing or prestation paid must be the very thing or prestation due.
Payment must be complete, unless partial payment is accepted or legally allowed.

C. Identity of the Prestation

The debtor cannot compel the creditor to accept a different thing or service from what is due, even if the substitute is of equal or greater value. This is the principle of identity of prestation.

For example, if D owes C a specific car, D cannot force C to accept a different car. If D owes ₱100,000, D generally cannot compel C to accept property instead of money.

There are exceptions where the creditor voluntarily accepts another prestation, such as in dacion en pago.

D. Integrity or Completeness of Payment

A creditor generally cannot be compelled to accept partial performance. Likewise, the debtor cannot be required to make partial payment unless the obligation so provides.

If the obligation is for ₱100,000, the creditor may refuse ₱60,000 as full discharge. Partial payment extinguishes the obligation only to the extent accepted, unless the creditor agrees that it is full settlement.

E. Who May Pay

Payment may be made by:

The debtor;
The debtor’s authorized representative;
A third person interested in the obligation, such as a guarantor or surety;
A third person not interested in the obligation.

A third person who pays may acquire certain rights depending on whether payment was made with or without the debtor’s consent.

If payment is made with the debtor’s consent, the third person may generally recover the full amount and may be subrogated to the creditor’s rights.

If payment is made without the debtor’s consent, the payer may recover only insofar as the payment benefited the debtor.

If payment is made against the debtor’s will, recovery may be limited.

F. To Whom Payment Must Be Made

Payment must be made to:

The creditor;
The creditor’s successor-in-interest;
A person authorized to receive payment;
A third person if the payment redounds to the creditor’s benefit.

Payment to a wrong person does not generally extinguish the obligation unless the creditor is benefited or the law recognizes the payment as valid.

G. Payment to an Incapacitated Person

Payment to an incapacitated creditor is valid only insofar as the creditor was benefited. The law protects persons who cannot validly manage their property.

H. Payment to a Third Person

Payment to a third person may extinguish the obligation if:

The third person was authorized to receive payment;
The creditor ratifies the payment;
The creditor benefits from the payment;
The debtor acted in good faith under circumstances recognized by law.

I. Payment Made in Good Faith to One in Possession of Credit

Payment made in good faith to a person who appears to be in possession of the credit may be valid. This protects debtors who reasonably rely on apparent authority, especially in commercial dealings.

J. Application of Payments

When a debtor owes several debts of the same kind to the same creditor, and payment is insufficient to cover all, the question is: which debt is paid first?

This is governed by application of payments.

The debtor generally has the first right to designate the debt to which payment applies. If the debtor does not designate, the creditor may apply the payment in the receipt. If neither validly applies it, legal rules apply.

Usually, the most onerous debt is paid first. If all debts are of the same nature and burden, payment is applied proportionately.

K. Payment of Interest Before Principal

If a debt produces interest, payment is generally applied first to interest before principal, unless the creditor agrees otherwise.

This prevents a debtor from reducing principal while leaving accrued interest unpaid without the creditor’s consent.

L. Dacion en Pago

Dacion en pago is a special form of payment where the debtor delivers property to the creditor, and the creditor accepts it as equivalent performance of a monetary obligation.

Example: D owes C ₱1,000,000. Instead of paying money, D transfers a parcel of land to C, and C accepts it as payment.

Dacion en pago is treated as a form of sale, because ownership of property is transferred to satisfy a debt.

Its requisites generally include:

There is a debt in money;
The debtor alienates property to the creditor;
The creditor accepts the property as payment;
The parties agree that the obligation is extinguished to the extent agreed.

M. Payment by Cession

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

It differs from dacion en pago.

In dacion en pago, ownership of specific property is transferred to the creditor as payment.

In cession, creditors are generally given the right to sell the debtor’s property and apply the proceeds to the debts. Unless otherwise agreed, cession does not necessarily extinguish the obligations completely; it extinguishes them only to the extent of the net proceeds.

N. Tender of Payment and Consignation

A debtor who wants to pay may sometimes be prevented from doing so because the creditor refuses to accept payment, is absent, incapacitated, unknown, or because several persons claim the right to collect.

In such cases, the debtor may resort to tender of payment and consignation.

Tender of payment is the debtor’s offer to pay. Consignation is the deposit of the thing or amount due with the court.

Tender alone generally does not extinguish the obligation. Consignation, when properly made and accepted by the court, may extinguish it.

Consignation usually requires:

A valid existing debt;
Tender of payment, unless excused by law;
Prior notice to persons interested in the obligation;
Deposit of the thing or amount due with the proper court;
Subsequent notice of consignation.

Consignation is important because it protects a debtor from continuing liability, interest, penalties, or default when the creditor unjustifiably refuses payment.

III. Loss of the Thing Due

A. Concept

An obligation may be extinguished when the specific thing due is lost or destroyed without the debtor’s fault and before the debtor is in delay.

This applies primarily to obligations to give a determinate or specific thing.

Example: D is obliged to deliver a particular painting to C. Before delivery, and without D’s fault, the painting is destroyed by an accidental fire. The obligation may be extinguished.

B. Determinate and Generic Things

A key distinction must be made between determinate and generic obligations.

A determinate thing is particularly designated or physically segregated from all others of the same class.

A generic thing is identified only by kind or class.

If the obligation is to deliver a specific horse named “Thunder,” and Thunder dies without the debtor’s fault before delay, the obligation may be extinguished.

If the obligation is to deliver “one horse,” the obligation is not extinguished by the death of one horse because the debtor can deliver another. The rule is expressed in the civil law maxim: genus never perishes.

C. Loss in Legal Sense

Loss does not only mean physical destruction. A thing is considered lost when:

It perishes;
It goes out of commerce;
It disappears in such a way that its existence is unknown or it cannot be recovered.

For example, if a specific thing becomes legally prohibited from being sold or transferred, it may be considered legally lost.

D. Requisites for Extinguishment

For loss to extinguish an obligation to give, the following are generally required:

The obligation must be to deliver a determinate thing;
The thing is lost or destroyed;
The loss occurs without the debtor’s fault;
The debtor is not yet in delay;
The debtor has not assumed the risk of loss;
The law or contract does not impose liability despite the loss.

E. Effect of Debtor’s Fault or Delay

If the thing is lost through the debtor’s fault, the obligation is not extinguished. It is converted into an obligation to pay damages.

If the debtor is already in delay, he may be liable even if the loss is due to a fortuitous event.

Example: D was supposed to deliver a specific car on June 1. D unjustifiably failed to deliver. On June 5, the car was destroyed by a flood. Since D was already in delay, D may still be liable.

F. Fortuitous Event

A fortuitous event is an event that could not be foreseen or, though foreseen, was inevitable. Examples may include earthquakes, typhoons, floods, or other extraordinary events, depending on the facts.

For a fortuitous event to exempt the debtor, it must generally be the proximate and exclusive cause of the loss, without the debtor’s negligence.

G. Obligations to Do

When the obligation is to do, it may be extinguished when the prestation becomes legally or physically impossible without the debtor’s fault.

Example: A singer contracts to perform at a concert but becomes seriously ill without fault before the performance. Depending on the circumstances, the obligation may be extinguished.

H. Partial Loss

If the loss is partial, the court determines whether the partial loss is so important as to extinguish the obligation. If the remaining portion is still useful and substantially complies with the obligation, the debtor may still be required to perform, possibly with adjustment.

IV. Condonation or Remission of the Debt

A. Concept

Condonation or remission is the gratuitous abandonment by the creditor of his right against the debtor. It is, in substance, an act of liberality.

Example: C tells D, “You no longer have to pay the ₱50,000 you owe me.” If validly made and accepted, the obligation is extinguished.

B. Nature of Remission

Remission is essentially a donation. Therefore, rules on donations may apply, particularly when the remission is express.

Because it benefits the debtor without equivalent consideration, acceptance by the debtor is generally required.

C. Kinds of Remission

Remission may be:

Express — clearly and formally declared by the creditor;
Implied — inferred from the creditor’s acts.

It may also be:

Total — the entire obligation is forgiven;
Partial — only part of the obligation is forgiven.

D. Express Remission

Express remission must comply with the formalities of donations.

If the debt involves movable property, the rules on donation of movables may apply. If it involves immovable property or rights over immovables, stricter formalities may be required.

E. Implied Remission

Implied remission may arise from acts of the creditor that clearly indicate intent to forgive the debt.

For example, the voluntary delivery of a private document evidencing credit may imply renunciation of the action against the debtor.

However, remission is not lightly presumed. There must be a clear basis for concluding that the creditor intended to forgive the obligation.

F. Delivery of Evidence of Debt

If the creditor voluntarily delivers to the debtor the private document evidencing the debt, the law may presume that the debt has been remitted.

This presumption may be rebutted by evidence that the document was delivered for another reason.

G. Effect on Accessory Obligations

The remission of the principal debt extinguishes accessory obligations, such as guaranty, pledge, mortgage, or penalty.

However, remission of an accessory obligation does not necessarily extinguish the principal obligation.

Example: If C forgives D’s principal debt, the guarantor is also released. But if C releases only the guarantor, D may still remain liable.

H. Renunciation of Security

If a creditor renounces a mortgage, pledge, or guaranty, this does not automatically mean that the principal debt is extinguished. It may simply mean that the creditor has given up the security but not the debt itself.

V. Confusion or Merger of Rights

A. Concept

Confusion or merger occurs when the qualities of creditor and debtor are united in the same person with respect to the same obligation.

Example: D owes C ₱100,000. Later, D becomes C’s sole heir and inherits C’s credit against D. D is now both debtor and creditor. The obligation is extinguished by merger.

B. Rationale

A person cannot be both creditor and debtor of himself in the same obligation. There is no practical or legal reason to enforce an obligation where the right to demand and the duty to perform are in the same person.

C. Requisites

Confusion requires:

The same person becomes both creditor and debtor;
The merger occurs in the same obligation;
The merger is complete and definite;
The obligation is not preserved by law or agreement for the benefit of third persons.

D. Merger Must Be in the Principal Parties

Confusion affecting the principal debtor or creditor extinguishes the principal obligation.

If confusion occurs only with respect to a guarantor, the principal obligation generally remains. The guaranty may be extinguished, but the debtor remains liable.

E. Joint Obligations

In joint obligations, merger involving one debtor or creditor extinguishes only the corresponding share, not the entire obligation.

F. Solidary Obligations

In solidary obligations, the effect of confusion may be broader, but internal reimbursement rights among solidary parties must be considered.

For example, if one solidary debtor becomes the creditor, the obligation may be extinguished as to the creditor-debtor relationship, but issues of contribution among co-debtors may arise.

VI. Compensation

A. Concept

Compensation occurs when two persons are creditors and debtors of each other in their own right. Their obligations 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 avoids unnecessary exchange of payments.

B. Kinds of Compensation

Compensation may be:

Legal compensation — takes place by operation of law;
Voluntary or conventional compensation — by agreement of the parties;
Judicial compensation — declared by the court in litigation;
Facultative compensation — may be claimed by one party who has the right to oppose or 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 commenced by third persons and communicated in due time to the debtor.

If these requisites are present, compensation occurs by operation of law, even without the parties’ knowledge.

D. Principal Creditor and Principal Debtor

Each party must be bound principally. A guarantor cannot generally set up compensation based on a debt owed by the creditor to the principal debtor, unless the law allows it.

E. Debts Must Be Due, Liquidated, and Demandable

A debt is due when its period has arrived.

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

A debt is demandable when it can already be enforced in court.

Unliquidated claims for damages generally do not give rise to legal compensation until determined.

F. Compensation and Assignment of Credit

If a credit is assigned to a third person, compensation may still be available depending on whether the debtor consented to the assignment and whether the debtor had knowledge of it.

The law protects debtors from losing defenses that already existed before assignment.

G. Prohibited Compensation

Compensation is not allowed in certain cases, including obligations arising from:

Depositum;
Commodatum;
Claims for support due by gratuitous title;
Certain obligations where compensation would defeat public policy or fiduciary duties.

For example, a depositary cannot ordinarily refuse to return the deposited thing by claiming that the depositor owes him money.

H. Effect of Compensation

Compensation extinguishes both debts to the concurrent amount.

If the debts are equal, both are extinguished.

If unequal, the smaller debt is extinguished, and the larger debt remains as to the balance.

VII. Novation

A. Concept

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

It is both a mode of extinguishing an obligation and a mode of creating a new obligation.

Example: D owes C ₱500,000 payable in cash. Later, C and D agree that instead of paying cash, D will deliver a vehicle, and the original obligation is extinguished. This may be novation if the requisites are present.

B. Requisites

Novation generally requires:

A previous valid obligation;
Agreement of all parties to the new obligation;
Extinguishment of the old obligation;
Validity of the new obligation.

C. Novation Is Never Presumed

Novation must be clear.

It may be:

Express — the parties clearly declare that the old obligation is extinguished; or
Implied — the old and new obligations are incompatible in every point.

Mere modification of terms does not always amount to novation.

For example, extension of time to pay, reduction of interest, or restructuring may not necessarily extinguish the old obligation unless the parties clearly intended novation or the new terms are incompatible with the old obligation.

D. Objective or Real Novation

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

Examples:

Changing the prestation from payment of money to delivery of property;
Replacing the principal condition of the obligation;
Altering the essential terms so substantially that the old obligation cannot coexist with the new one.

E. Subjective or Personal Novation

Subjective novation changes the parties.

It may involve:

Substitution of the debtor;
Subrogation of a third person in the rights of the creditor.

F. Substitution of Debtor

Substitution of debtor may occur by:

Expromision — a third person assumes the debtor’s obligation without the debtor’s initiative, but with the creditor’s consent;
Delegacion — the debtor proposes a new debtor, and the creditor accepts.

Creditor consent is essential because the identity and solvency of the debtor matter.

G. Expromision

In expromision, the initiative comes from the third person or creditor, not necessarily from the original debtor.

Example: X tells C, “I will pay D’s debt to you, and D will be released.” If C agrees to release D and accept X as the new debtor, there may be novation by expromision.

H. Delegacion

In delegacion, the original debtor delegates another person to assume the debt.

Example: D tells C, “Please accept X as the new debtor in my place.” C agrees, and X accepts. The original obligation may be extinguished.

I. Subrogation

Subrogation transfers to a third person the rights of the creditor.

It may be legal or conventional.

In subrogation, the obligation may not be extinguished in the absolute sense as to the debt itself; rather, the creditor is replaced. From the original creditor’s perspective, the obligation is satisfied, but the debtor may remain liable to the subrogee.

J. Effect of Novation on Accessory Obligations

If the principal obligation is extinguished by novation, accessory obligations are generally also extinguished unless reserved or unless they benefit third persons who did not consent.

For example, a guaranty may be extinguished if the principal obligation is novated without the guarantor’s consent.

K. Void Old or New Obligation

If the original obligation is void, there is generally nothing to novate.

If the new obligation is void, novation generally does not take effect, and the old obligation may subsist unless the parties intended otherwise and the law allows such consequence.

VIII. Annulment

A. Concept

Annulment extinguishes obligations arising from a voidable contract once the contract is annulled.

A voidable contract is valid and binding until annulled. When annulled, the parties are generally restored to their original positions through mutual restitution.

B. Grounds for Annulment

Voidable contracts may include those where consent was vitiated by:

Minority or incapacity;
Mistake;
Violence;
Intimidation;
Undue influence;
Fraud.

C. Effect of Annulment

When a contract is annulled, the obligations created by it are extinguished, subject to restitution.

Each party must generally return what he received.

If return is impossible, value and damages may be considered according to the circumstances.

D. Distinction from Rescission

Annulment is based on a defect in consent or capacity. Rescission is based on economic prejudice or lesion in cases provided by law.

IX. Rescission

A. Concept

Rescission is a remedy that extinguishes obligations by setting aside a valid contract due to economic damage or legally recognized injury.

A rescissible contract is valid until rescinded.

B. Grounds for Rescission

Rescission may apply in cases such as:

Contracts entered into by guardians when the ward suffers lesion beyond the amount provided by law;
Contracts agreed upon in representation of absentees, if lesion exists;
Contracts undertaken in fraud of creditors;
Contracts involving things under litigation entered into without required approval;
Other cases specially declared by law.

C. Rescission for Breach

In reciprocal obligations, a party may seek rescission when the other party substantially breaches the obligation.

For example, in a contract of sale, if the buyer fails to pay and the breach is substantial, the seller may seek rescission under applicable Civil Code rules.

D. Effect of Rescission

Rescission generally requires mutual restitution. The parties return what they received, together with fruits and interest when appropriate.

Rescission will not be allowed if the party seeking it cannot return what he is obliged to restore.

E. Subsidiary Nature

Rescission is generally subsidiary. It is not available when the injured party has another adequate legal remedy, except in cases where the law permits direct rescission.

X. Fulfillment of a Resolutory Condition

A. Concept

A resolutory condition is a future and uncertain event upon which the extinguishment of an obligation depends.

The obligation is effective immediately, but it is extinguished once the condition happens.

Example: A allows B to use a property until B passes the bar examinations. B’s passing of the bar is a resolutory condition. Once it happens, B’s right to use the property ends.

B. Distinction from Suspensive Condition

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

A resolutory condition extinguishes an already existing obligation upon happening of the condition.

C. Effect

Upon fulfillment of the resolutory condition, the obligation is extinguished. Depending on the nature of the obligation, restitution may be required.

For obligations to give, the parties may have to return what they received, subject to rules on fruits, interests, deterioration, improvements, and loss.

XI. Prescription

A. Concept

Prescription extinguishes rights and actions by the lapse of time. In obligations, it often means the creditor loses the right to enforce the obligation in court after the legally fixed period.

Strictly, prescription may extinguish the action rather than the natural obligation itself. After prescription, the debtor may have a defense against judicial enforcement.

B. Rationale

Prescription promotes stability, discourages stale claims, and protects persons from having to defend against old demands where evidence may already be lost.

C. Examples of Prescriptive Periods

Common prescriptive periods under Philippine civil law include:

Written contracts — generally ten years;
Oral contracts — generally six years;
Injury to rights of plaintiff — generally four years;
Quasi-delict — generally four years;
Certain actions involving immovable property — longer periods depending on the action and circumstances.

The exact prescriptive period depends on the nature of the obligation and the applicable law.

D. Interruption of Prescription

Prescription may be interrupted by:

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

Once interrupted, the period may begin anew depending on the circumstances.

E. Waiver of Prescription

Prescription already acquired may be waived, but future prescription generally cannot be waived in advance in a way contrary to law or public policy.

XII. Other Causes of Extinguishment

Article 1231 recognizes that other causes may extinguish obligations. These are governed by other provisions of the Civil Code or special laws.

A. Mutual Desistance or Mutual Withdrawal

Parties may mutually agree to cancel or abandon their contract. Since contracts are generally obligatory between the parties, they may also be extinguished by mutual agreement, provided no law, public policy, or third-party right is violated.

Example: A contractor and owner agree to cancel a construction contract before substantial performance. Their mutual desistance may extinguish their obligations, subject to settlement of accrued rights.

B. Compromise

A compromise is a contract where parties make reciprocal concessions to avoid litigation or end one already commenced.

If the compromise validly settles the dispute, the original claims may be extinguished and replaced by the compromise agreement.

Example: C claims D owes ₱1,000,000. D disputes the amount. They agree that D will pay ₱600,000 in full settlement. The disputed obligation is extinguished according to the compromise terms.

C. Death

Death does not generally extinguish obligations because obligations may be transmitted to heirs or the estate.

However, death may extinguish obligations that are purely personal.

Examples:

A contract for a particular artist to paint a portrait may be extinguished by the artist’s death;
A personal service contract based on special qualifications may be extinguished;
Agency may be extinguished by death of the principal or agent, subject to exceptions.

Money debts generally survive death and are charged against the estate.

D. Arrival of a Resolutory Term

An obligation may be extinguished upon arrival of a day certain if the term is resolutory.

Example: A lease for one year ends upon expiration of the one-year period.

Unlike a condition, a term is certain to arrive, although the exact date may sometimes be uncertain.

E. Impossibility or Illegality of Performance

If performance becomes legally or physically impossible without the debtor’s fault, the obligation may be extinguished.

Example: A contract to deliver a product may become impossible if a subsequent law prohibits its sale, provided the debtor is not at fault and has not assumed the risk.

F. Revocation

Some juridical relations may be extinguished by revocation, especially when the law allows unilateral withdrawal.

Examples:

Agency may generally be revoked by the principal;
Donations may be revoked in cases allowed by law;
Certain offers may be withdrawn before acceptance, subject to rules on option contracts and reliance.

G. Expiration of Contractual Period

Many obligations are extinguished simply because the agreed period ends.

Example: Employment, lease, service, distribution, franchise, or supply agreements may end upon expiration, subject to renewal clauses, labor laws, or special laws.

H. Fulfillment of Purpose

Some obligations are tied to a specific purpose. Once the purpose is fulfilled, the obligation ends.

Example: A person is engaged to organize a particular event. Once the event is completed and the organizer is paid, the obligation is extinguished by performance and completion of purpose.

I. Happening of a Termination Event

Modern contracts often contain termination clauses. These may include:

Non-payment;
Insolvency;
Material breach;
Change of control;
Force majeure lasting beyond a specified period;
Regulatory prohibition;
Failure to obtain permits.

When the contract validly provides that such event terminates obligations, the parties’ duties may be extinguished according to the contract.

XIII. Effect of Extinguishment on Accessory Obligations

A principal obligation and its accessory obligations are connected.

As a rule:

The extinguishment of the principal obligation extinguishes the accessory obligations.

Examples of accessory obligations include:

Interest;
Penalties;
Pledges;
Mortgages;
Guaranties;
Suretyships;
Liens;
Security arrangements.

However:

The extinguishment of an accessory obligation does not necessarily extinguish the principal obligation.

Example: If a mortgage is released, the loan may still remain payable unless the creditor also remits or extinguishes the debt.

XIV. Distinctions Among the Principal Modes

Payment vs. Dacion en Pago

Payment is performance of the exact prestation due. Dacion en pago is performance by giving something different, accepted by the creditor as equivalent payment.

Dacion en Pago vs. Payment by Cession

Dacion transfers ownership of specific property to the creditor as payment. Cession assigns property to creditors for sale and application of proceeds.

Remission vs. Payment

Payment involves satisfaction by performance. Remission involves forgiveness without equivalent performance.

Compensation vs. Confusion

Compensation involves two persons who are mutual creditors and debtors. Confusion involves one person becoming both creditor and debtor in the same obligation.

Compensation vs. Payment

Payment requires actual performance. Compensation extinguishes obligations by operation of law or agreement because reciprocal debts cancel each other.

Novation vs. Modification

Novation extinguishes the old obligation and creates a new one. Modification merely changes terms while preserving the original obligation.

Rescission vs. Annulment

Rescission sets aside a valid contract due to injury or breach. Annulment sets aside a voidable contract due to defective consent or incapacity.

Resolutory Condition vs. Resolutory Period

A resolutory condition is uncertain. A resolutory period is certain to arrive.

XV. Obligations Not Easily Extinguished

Some obligations are treated strictly because of public policy, fiduciary character, or personal nature.

A. Support

Claims for support, especially those arising from family relations, are protected by law. Compensation is generally not allowed against support due by gratuitous title.

B. Deposits and Commodatum

A depositary or borrower in commodatum cannot ordinarily refuse return of the thing by invoking compensation. These contracts involve trust and specific return obligations.

C. Taxes and Public Obligations

Tax liabilities and public obligations are governed by special laws. Civil Code modes may not freely apply if inconsistent with tax law or public policy.

D. Labor Standards

Employee rights under labor law cannot generally be waived or extinguished by private agreement if the waiver violates labor standards or public policy.

XVI. Practical Philippine Applications

A. Loan Obligations

Loan obligations are commonly extinguished by:

Full payment;
Dacion en pago;
Compensation, if the creditor also owes the debtor;
Remission;
Prescription;
Novation through restructuring, if clearly intended.

A mere extension of payment period usually does not extinguish the loan unless novation is clear.

B. Sale of Goods or Property

Obligations in sales may be extinguished by:

Delivery and payment;
Loss of a specific object without fault before delay;
Rescission for substantial breach;
Annulment if consent was defective;
Fulfillment of resolutory conditions in the contract.

C. Lease

Lease obligations may be extinguished by:

Expiration of lease period;
Mutual agreement;
Rescission or termination for breach;
Loss or destruction of the leased property;
Merger, if lessee becomes owner-lessor in the same right;
Legal ejectment or termination under applicable law.

D. Construction Contracts

Construction obligations may be extinguished by:

Completion and acceptance of the work;
Payment;
Rescission for breach;
Impossibility due to force majeure;
Mutual termination;
Novation through revised scope or replacement contract.

E. Employment and Personal Service

Personal service obligations may be extinguished by:

Performance;
Expiration of term;
Death or incapacity where personal qualifications are essential;
Lawful termination;
Mutual separation agreement;
Supervening illegality.

Labor laws and public policy must always be considered.

F. Guaranty and Suretyship

A guaranty or suretyship may be extinguished by:

Payment of the principal obligation;
Remission of the principal debt;
Novation without the guarantor’s or surety’s consent, where prejudicial;
Release of the guarantor;
Material alteration of the principal obligation;
Other defenses available under law.

XVII. Evidentiary Considerations

In practice, proving extinguishment is often as important as the mode itself.

A debtor claiming extinguishment should preserve evidence such as:

Official receipts;
Acknowledgment letters;
Deeds of dacion en pago;
Settlement agreements;
Release, waiver, or quitclaim documents;
Court consignation records;
Proof of loss or fortuitous event;
Communications showing creditor consent;
Written novation agreements;
Proof of prescription and absence of interruption.

The burden of proving payment or extinguishment generally rests on the party asserting it.

XVIII. Effect of Invalid Extinguishment

If the alleged mode of extinguishment is invalid, the obligation may remain enforceable.

Examples:

Payment to an unauthorized person may not discharge the debtor;
Novation without creditor consent is ineffective;
Remission without required formalities may be invalid;
Consignation without compliance with legal requisites may fail;
Compensation may not apply if one debt is not yet due or liquidated;
Loss due to debtor’s negligence does not extinguish liability;
A waiver contrary to law or public policy may be void.

Thus, parties should not assume that an obligation is extinguished merely because they intended it. The legal requisites must be satisfied.

XIX. Summary Table

Mode	Basic Idea	Key Effect
Payment or performance	Fulfillment of the prestation	Obligation is satisfied
Loss of the thing due	Specific thing is lost without debtor’s fault before delay	Obligation may be extinguished
Remission or condonation	Creditor forgives the debt	Obligation is waived or released
Confusion or merger	Creditor and debtor become the same person	Obligation disappears
Compensation	Mutual debts cancel each other	Debts extinguished to concurrent amount
Novation	New obligation replaces old one	Old obligation extinguished
Annulment	Voidable contract is set aside	Obligations under contract extinguished, subject to restitution
Rescission	Valid contract is set aside due to injury or breach	Parties restored, subject to legal rules
Resolutory condition	Event occurs that ends obligation	Obligation extinguished upon condition
Prescription	Legal period to enforce lapses	Action or enforceability is barred
Other causes	Death, mutual desistance, compromise, term expiration, impossibility, special law	Depends on governing rule

XX. Conclusion

The extinguishment of obligations under Philippine law is governed principally by the Civil Code, especially Article 1231. The six principal modes are payment or performance, loss of the thing due, remission, confusion, compensation, and novation. These are supplemented by annulment, rescission, fulfillment of a resolutory condition, prescription, and other causes recognized by law, contract, or special legal provisions.

The most important practical lesson is that extinguishment depends not merely on intention but on legal requisites. Payment must be made properly. Loss must be without fault and must involve a determinate prestation. Remission must comply with rules on donations when applicable. Compensation requires mutual, due, liquidated, and demandable debts. Novation must be clear and cannot be presumed. Rescission and annulment require legally recognized grounds. Prescription depends on the nature of the action and may be interrupted.

In Philippine civil law, obligations are binding, but they are not perpetual. They end when the law, the parties’ agreement, or the nature of the prestation recognizes that the juridical necessity has been satisfied, cancelled, merged, replaced, barred, or otherwise legally terminated.
