General Provisions

Concept and Place of Obligations

An obligation is a juridical necessity to give, to do, or not to do, and the word necessity means that the debtor may be compelled by law to perform or answer in damages when performance is no longer legally or practically attainable.

The Civil Code definition treats an obligation as a legal bond between at least two persons: one may demand a prestation, and the other must render it. It is not a mere moral duty, social expectation, or statement of intention, because the creditor has a legally protected interest in performance.

Obligations belong to patrimonial law because their breach ordinarily results in specific performance, substitute performance, rescission when proper, or damages. Even when the prestation involves personal conduct, the legal consequence is enforceable through property, indemnity, or other civil remedies.

The general provisions govern the basic life of an obligation: how it is understood, where it comes from, what performance requires, what breach produces, and what remedies protect the creditor before the more specific rules on kinds, extinguishment, and particular contracts are applied.

Structural Elements

A civil obligation is complete only when the persons, the prestation, and the juridical tie can be identified with sufficient certainty. Without these elements, there may be negotiation, courtesy, moral pressure, or factual expectation, but no enforceable civil obligation.

The prestation is the conduct due, while the thing, service, or abstention is the object through which the prestation is carried out. In an obligation to give, the debtor's act is delivery; in an obligation to do, the debtor's act is service or performance; in an obligation not to do, the debtor's duty is abstention.

An obligation may exist without a written instrument if the law recognizes its source and the facts establish its elements. Writing is required only when a statute, the nature of the transaction, or the rule on proof makes form material to validity, enforceability, or admissibility.

Sources of Civil Obligations

Article 1157 of the Civil Code gives the principal sources of obligations: law, contracts, quasi-contracts, acts or omissions punished by law, and quasi-delicts. The enumeration supplies the legal origin of the juridical tie and prevents courts from enforcing duties based only on sentiment or convenience.

Obligations arising from law are not presumed, because a person is bound by law only when the statute or legal rule clearly imposes the duty. Examples include family support, tax liabilities, statutory benefits, legal easements, and obligations attached by law to certain juridical relations.

Obligations arising from contracts have the force of law between the parties because autonomy of contracts allows persons to create binding rules for their own transaction. Contractual stipulations must still yield to law, morals, good customs, public order, and public policy.

Obligations arising from quasi-contracts rest on the principle that no one shall be unjustly enriched at another's expense. They do not depend on consent, but on a lawful, voluntary, and unilateral act that creates an equitable duty to return, reimburse, or account.

Obligations arising from crimes are the civil consequences of punishable acts or omissions. Civil liability may include restitution, reparation, and indemnification, subject to the rules governing criminal proceedings and the separate treatment of civil actions when the law allows reservation or independent enforcement.

Obligations arising from quasi-delicts are based on fault or negligence causing damage, where the law imposes liability independent of a contract. The duty is grounded on the breach of the general obligation to observe due care toward others.

A single factual incident may generate obligations from different sources, but recovery cannot duplicate the same loss. The source matters because it affects pleading, defenses, prescription, measure of diligence, burden of proof, and the persons who may be held liable.

Civil, Natural, and Moral Duties

A civil obligation gives a right of action to compel performance or its civil equivalent. It is the ordinary concern of the general provisions on obligations because the creditor can invoke judicial remedies against the debtor.

A natural obligation is based on equity and natural law but lacks an action to compel performance. Once the debtor voluntarily performs with knowledge of the facts, the law authorizes the creditor to retain what was delivered or paid.

A moral obligation rests only on conscience, affection, or social duty and has no civil effect unless it is converted into a juridical obligation by law, contract, or another recognized source. The distinction matters because courts enforce legal bonds, not generosity or honor alone.

Principal Kinds by Prestation

The general provisions organize obligations according to the kind of prestation because the remedy for breach depends on what was due. The same debtor may be bound to give, to do, and not to do under one transaction, but each prestation is analyzed according to its own legal incidents.

Obligation to Give

In an obligation to give a determinate thing, the debtor must preserve the thing with the diligence of a good father of a family unless the law or stipulation requires another standard. The debtor must deliver the thing itself, its accessions, and its accessories, even if not mentioned.

The creditor acquires a personal right to demand delivery from the moment the obligation arises, but ownership or real right over the thing is generally acquired only by delivery. This distinction explains why a creditor may sue before delivery but does not automatically become owner by the mere existence of the obligation.

The creditor has a right to the fruits of a determinate thing from the time the obligation to deliver it arises. Actual ownership of the fruits still follows the rules on delivery and acquisition of real rights.

In an obligation to give a generic thing, the debtor may deliver any thing belonging to the agreed class and quality. If the debtor fails, the creditor may obtain performance at the debtor's expense because a genus is not extinguished by the loss of particular items within the class.

Obligation to Do

In an obligation to do, the debtor must render the service or act promised according to the terms and standard required by the obligation. If the debtor refuses or performs poorly, the creditor may have the act done at the debtor's cost when substitute performance is legally possible.

When the act is personal and depends on the debtor's qualifications, confidence, artistry, or discretion, courts do not compel physical performance. The usual civil consequence is damages, because forced personal service would offend personal liberty and may produce performance different from what was promised.

Obligation Not to Do

In an obligation not to do, breach consists of doing the prohibited act. The remedy is to undo what was done when undoing is possible, together with damages when the creditor suffered compensable injury.

If undoing is impossible or would violate law or rights of third persons, the obligation is converted into liability for damages or other proper relief. The negative character of the prestation does not make the obligation less enforceable.

Performance, Breach, and Liability

The debtor is liable for damages when, in the performance of the obligation, the debtor is guilty of fraud, negligence, delay, or any manner of contravention of the tenor of the obligation. These grounds capture deliberate breach, careless breach, late performance, and performance inconsistent with what was promised or imposed by law.

Delay generally begins only after the creditor makes a judicial or extrajudicial demand. Demand is unnecessary when the obligation or law so declares, when time is a controlling motive for the obligation, or when demand would be useless because performance has become impossible through the debtor's act or fault.

In reciprocal obligations, one party does not incur delay if the other party does not perform or is not ready to perform what is incumbent upon that party. Delay begins when one party performs or validly offers performance and the other fails to comply.

Fraud in performance is different from fraud that vitiates consent. The first presupposes an existing obligation and concerns its breach; the second affects the formation or validity of the juridical act that created the obligation.

Negligence is measured by the diligence required by law, stipulation, or the nature of the obligation. If the obligation does not state a standard, the Civil Code supplies the diligence of a good father of a family as the ordinary baseline.

Fortuitous Events and Risk

A fortuitous event is an occurrence independent of the debtor's will that could not be foreseen or, though foreseen, was unavoidable. It relieves the debtor only when it makes performance legally or physically impossible and the debtor is free from participation, aggravation, or delay.

The debtor remains liable despite fortuitous event when the law so provides, when the parties stipulate liability, when the nature of the obligation requires assumption of risk, or when the debtor is already in delay. A debtor who promised the same determinate thing to two or more persons with different interests also bears a heavier risk.

Loss of a determinate thing without the debtor's fault may extinguish the obligation to deliver that thing, subject to the exceptions on risk. Loss of generic things does not ordinarily extinguish the obligation because the debtor can still obtain items from the same genus.

Creditor Protection

The general provisions do not leave the creditor with only a passive right to wait for payment. The law gives remedies to preserve the value of the debtor's patrimony and prevent the debtor from defeating collection through inaction or fraudulent transfers.

After pursuing the debtor's property, creditors may exercise the debtor's rights and actions except those that are purely personal. This remedy allows the creditor to step into economic rights that the debtor neglects, but it does not allow intrusion into personal status, family rights, or rights inseparable from the debtor.

Creditors may also impugn acts done by the debtor in fraud of their rights after exhausting available property. This remedy protects the creditor against dispositions that diminish the debtor's assets in a manner legally prejudicial to collection.

These protective remedies reflect the patrimonial nature of obligations: the creditor's practical assurance is the debtor's property, and the law prevents the debtor from making that assurance illusory.

Payment Presumptions and Transmission

The Civil Code recognizes practical presumptions connected with payment. When the creditor receives the principal without reservation as to interest, the interest is presumed paid; when a later installment is received without reservation, prior installments are presumed paid.

These presumptions are disputable and operate as rules of evidence drawn from ordinary business conduct. They encourage creditors to make timely reservations when accepting partial or sequential payments.

Rights acquired by virtue of an obligation are generally transmissible. Transmission may be barred by law, by stipulation, or by the nature of the right, especially when the obligation is personal or founded on confidence in a particular person.

Death does not automatically extinguish civil obligations because patrimonial rights and liabilities generally pass to the estate. Personal obligations, strictly personal services, and rights made non-transmissible by law or agreement are treated differently because their value depends on the identity of the person bound or benefited.

Relationship with Contracts and Remedies

Every valid contract gives rise to obligations, but not every obligation arises from contract. The broader law of obligations includes duties created directly by law, equity, criminal acts, and negligence, even without contractual consent.

The creditor's remedies depend on the source and prestation involved. For obligations to give, the remedy may include delivery, substitute acquisition, or damages; for obligations to do, performance by another or damages may be proper; for obligations not to do, undoing and damages are the usual consequences.

Damages are not a separate source of obligation but a civil consequence of breach or wrongful injury. They translate the creditor's legally protected interest into compensation when exact fulfillment is absent, delayed, defective, or no longer possible.

Rescission or resolution may be available in proper reciprocal obligations when one party substantially breaches what is incumbent upon that party. It is not the ordinary remedy for every breach, because the nature of the obligation, the gravity of nonperformance, and the governing legal rule determine the remedy.

Integrated View

The general provisions should be read as a sequence. First, identify the legal bond and its source; second, determine the prestation and its required standard; third, ask whether performance is due, defective, delayed, impossible, or excused; and fourth, apply the remedy that corresponds to the source, prestation, and breach.

The controlling idea is that an obligation is both a relationship and a remedy-bearing duty. It links a creditor and debtor through a legally recognized source, directs a definite prestation, and supplies consequences when the debtor fails to perform according to law or agreement.
