Nature of Obligations
An obligation is a juridical necessity to give, to do, or not to do. Its civil effect is that the debtor is bound to perform the prestation according to its tenor, while the creditor acquires enforceable rights to exact performance, substitute performance when allowed, and damages when the law or the obligation so permits.
The prestation is the object of the obligation. It must be possible, determinate or determinable, licit, and susceptible of pecuniary valuation. The nature of the prestation determines the creditor's remedies, the debtor's required diligence, the allocation of risk, and the consequences of breach.
Obligations to give are real obligations because the prestation consists in the delivery of a thing. Obligations to do and not to do are personal obligations because the prestation consists in an act or abstention. This classification matters because delivery of a thing, execution of a service, and observance of a prohibition are enforced in different ways.
Obligations to Give
In an obligation to give, the debtor must deliver the thing due, preserve it with the required diligence before delivery, deliver its accessions and accessories when the thing is determinate, and answer for breach under the rules on delay, fraud, negligence, fortuitous events, and damages.
A determinate thing is particularly designated or physically segregated from all others of the same class. The creditor may compel delivery of that very thing because no substitute is due without the creditor's consent. A generic thing is identified only by its class or kind, so the creditor may demand delivery of a thing of the agreed quality, and performance may be obtained at the debtor's expense if the debtor fails to deliver.
The debtor of a determinate thing must take care of it with the diligence of a good father of a family unless the law or the stipulation of the parties requires another standard. This duty begins when the obligation to deliver arises and continues until actual or constructive delivery, valid tender followed by creditor delay, or another legally recognized mode of extinguishment.
The diligence of a good father of a family means ordinary care measured by the nature of the obligation and the circumstances of persons, time, and place. If the obligation, the parties' agreement, or a special law imposes a higher degree of care, the debtor is liable for falling below that higher standard.
The creditor has a personal right to the fruits of the thing from the time the obligation to deliver arises. The creditor acquires no real right over the thing until delivery. Before delivery, the creditor may demand performance and damages, but ownership or another real right is generally transferred only by tradition or by another legally effective mode.
Fruits include natural fruits, industrial fruits, and civil fruits. The debtor who withholds a determinate thing after the obligation to deliver has arisen may be liable to account for fruits, especially when delay, bad faith, or another breach is present.
The duty to deliver a determinate thing includes all accessions and accessories, even if they were not expressly mentioned. Accessions are additions or improvements produced by or incorporated into the principal thing. Accessories are things intended for the embellishment, use, preservation, or completion of the principal thing.
For a generic obligation, the debtor is not discharged by the loss of items the debtor intended to deliver, because the genus does not perish. The creditor may procure equivalent goods at the debtor's expense, demand damages, or seek other proper relief. If the generic object is limited to a particular source or stock, loss of that delimited genus may have different effects because the obligation is no longer purely generic.
Obligations to Do
In an obligation to do, the debtor must perform the agreed act in the manner, quality, and time required by the obligation. If the debtor fails to perform, performs contrary to the terms, or performs poorly, the creditor may have the act done by another at the debtor's expense when substitution is possible.
When the act requires the debtor's personal qualifications, confidence, taste, skill, or relationship to the creditor, the debtor cannot be physically compelled to render the personal service. The ordinary consequences are damages, rescission when proper, or other lawful remedies, because civil enforcement cannot become involuntary personal service.
If the debtor performs the act in contravention of the terms of the obligation, the defective work may be ordered undone at the debtor's expense when undoing is possible and equitable. Damages may be recovered for loss caused by the defective performance, including loss resulting from delay in correction.
Performance by a third person at the debtor's expense is appropriate only when the prestation is not strictly personal and the substitute performance substantially gives the creditor what was promised. If the very identity or personal ability of the debtor was the principal inducement, substitute performance does not fully satisfy the obligation unless the creditor accepts it.
Obligations Not to Do
In an obligation not to do, the debtor is bound to abstain from an act. Breach occurs by doing the prohibited act, and delay is generally inapplicable because the breach is complete upon violation of the negative undertaking.
If the prohibited act can be undone, the debtor may be required to undo it at the debtor's expense. If undoing is impossible, useless, or inequitable, the creditor's remedy is normally damages, without prejudice to injunction or other relief when available under procedural law.
Negative obligations often protect confidentiality, non-competition within lawful limits, peaceful possession, exclusive use, or preservation of a condition. Their enforcement depends on the validity of the restriction and the availability of a remedy that does not violate law, morals, good customs, public order, or public policy.
Breach and Liability for Damages
Those who in the performance of their obligations are guilty of fraud, negligence, or delay, and those who in any manner contravene the tenor of their obligations, are liable for damages. These four grounds cover intentional evasion, lack of required care, legally recognized default, and violation of the agreed terms even when the breach does not fit neatly into the first three categories.
| Ground | Basic Meaning | Usual Effect |
|---|---|---|
| Fraud | Voluntary and intentional evasion of the normal fulfillment of the obligation. | Liability for all damages attributable to the deliberate breach; future fraud cannot be validly waived. |
| Negligence | Failure to observe the diligence required by the obligation, law, stipulation, or circumstances. | Liability may be regulated by the courts according to the circumstances. |
| Delay | Failure to perform on time after demand, or without demand when demand is legally unnecessary. | Damages, liability for risk in proper cases, and other consequences of default. |
| Contravention of tenor | Performance inconsistent with the terms, mode, quality, place, or conditions of the obligation. | Specific relief, correction, undoing, or damages depending on the prestation. |
Fraud in the performance of an obligation is not the same as fraud used to obtain consent to a contract, although both may produce civil consequences. Fraud in performance assumes an existing valid obligation and concerns the debtor's deliberate evasion of faithful fulfillment.
Responsibility for fraud cannot be waived in advance because such a waiver would encourage intentional breach. A waiver made after the fraud has been committed is treated differently because the creditor may knowingly compromise or renounce an existing claim, subject to the rules on consent, capacity, and validity of settlements.
Negligence is measured by the nature of the obligation and by the circumstances of persons, time, and place. When the obligation does not state the required care and no special law fixes it, the standard is the diligence of a good father of a family.
Courts may temper liability arising from negligence according to the circumstances. However, gross negligence may be treated as approaching bad faith when it shows a want of even slight care or a conscious indifference to consequences.
Contravention of the tenor of the obligation is broad. It includes delivery of the wrong thing, delivery at the wrong place, performance in a prohibited manner, partial or defective performance not accepted by the creditor, and violation of incidental undertakings that form part of the obligation.
Delay or Mora
Delay is not every failure to perform on the due date. Legal delay generally begins only when the creditor judicially or extrajudicially demands performance and the debtor still fails to comply.
Demand is unnecessary when the obligation or the law expressly so declares, when time was the controlling motive for the establishment of the obligation, or when demand would be useless because the debtor has rendered performance beyond the debtor's power. Demand is also unnecessary in reciprocal obligations once one party has performed or is ready and willing to perform and the other does not comply.
Mora solvendi is delay by the debtor. It requires a valid and demandable obligation, nonperformance by the debtor at the time performance is due, demand by the creditor unless demand is excused, and failure to perform despite demand. Its consequences may include damages, interest when proper, and liability for loss of a determinate thing even by fortuitous event in the cases provided by law.
Mora accipiendi is delay by the creditor. It arises when the creditor unjustifiably refuses a valid tender of performance. Its effects may include relieving the debtor from liability for subsequent delay, shifting certain risks to the creditor, stopping the running of interest in proper cases, and allowing consignation when the legal requisites are present.
Compensatio morae occurs in reciprocal obligations when both parties are in delay. The delay of one is offset by the delay of the other until one party performs or is ready to perform; from that moment, the other party who fails to comply incurs delay.
In obligations not to do, mora is ordinarily irrelevant because the debtor breaches the obligation by performing the forbidden act. The legal consequences arise from the violation itself, not from a demand to abstain after the act has been done.
Fortuitous Events and Allocation of Risk
A fortuitous event is an occurrence independent of the debtor's will which could not be foreseen, or which, though foreseen, was inevitable, and which makes normal performance impossible. It excuses liability only when the event is the proximate and adequate cause of the loss or nonperformance and the debtor is free from participation, aggravation, or concurrent negligence.
The debtor is generally not liable for fortuitous events. The rule rests on fairness: a person should not answer for loss caused solely by an event beyond human control or beyond the debtor's legal responsibility.
The exemption does not apply when the law so provides, when the parties stipulate liability even for fortuitous events, when the nature of the obligation requires assumption of risk, when the debtor is already in delay, or when the debtor has promised to deliver the same determinate thing to two or more persons with different interests.
A debtor cannot invoke fortuitous event when negligence exposed the thing to the loss, worsened the damage, or prevented timely performance before the event occurred. The event must be the sole cause in the legal sense; if the debtor's fault cooperated with the event, liability may attach.
Fortuitous event is especially important in obligations to deliver determinate things because the loss of the specific thing may extinguish the obligation when the debtor is without fault and not in delay. In generic obligations, the debtor usually remains bound because other things of the same kind may still be delivered.
When the debtor is liable for fortuitous event by law, stipulation, delay, or assumption of risk, the loss of the thing does not necessarily extinguish liability. The obligation may be converted into an obligation to pay damages, value, interest, or other consequences fixed by law or agreement.
Effects According to the Kind of Prestation
| Kind of Obligation | Primary Duty | Creditor's Principal Remedies | Special Consequence |
|---|---|---|---|
| To give a determinate thing | Preserve and deliver the exact thing, including accessions and accessories. | Compel delivery, recover fruits when proper, and claim damages. | Real right over the thing is generally acquired only upon delivery. |
| To give a generic thing | Deliver a thing of the agreed kind and quality. | Obtain performance at the debtor's expense and claim damages. | Loss of selected items does not excuse performance unless the genus is legally or factually limited. |
| To do | Perform the agreed act properly and on time. | Substitute performance at debtor's expense when possible, correction, undoing, or damages. | Strictly personal acts cannot be physically compelled. |
| Not to do | Abstain from the prohibited act. | Undoing at debtor's expense, injunction when proper, and damages. | Breach occurs by doing the forbidden act; delay is usually irrelevant. |
Interest, Usury, and Receipts
The Civil Code refers usurious transactions to special laws. Statutory ceilings on interest have been removed, but stipulated interest remains subject to judicial control when it is unconscionable, iniquitous, or contrary to morals or public policy.
Interest as compensation for the use or forbearance of money is not presumed. It must be expressly stipulated in writing. If the stipulated rate is void for being unconscionable, the principal obligation remains, and the court may impose a reasonable rate or the applicable legal interest when proper.
Interest may also be imposed as damages for delay in payment of money. In that setting, the interest is a consequence of breach or delay, and its rate depends on the parties' valid agreement, special law, or the governing legal rate.
Receipt of the principal by the creditor without reservation as to interest gives rise to a presumption that the interest has been paid. Receipt of a later installment without reservation gives rise to a presumption that prior installments have been paid.
These presumptions are disputable. They may be overcome by proof that the creditor made a reservation, that payment was applied differently, that the receipt was issued by mistake, or that the circumstances negate the inference of full payment.
Creditor's Protective Remedies
After pursuing the debtor's property to satisfy the claim, creditors may exercise the debtor's rights and actions, except those inherent in the debtor's person. They may also impugn acts that the debtor performed in fraud of creditors.
The right to exercise the debtor's rights is commonly called accion subrogatoria. It allows the creditor to step into the debtor's place to enforce property rights that the debtor neglects to assert, because the debtor's patrimony is the common assurance of creditors.
Rights inherent in the person of the debtor cannot be exercised by creditors. These include rights inseparably linked to family relations, personal status, personal confidence, moral choices, or purely personal acts whose exercise belongs only to the debtor.
The right to attack fraudulent acts is commonly called accion pauliana. It protects creditors from transfers or transactions that diminish the debtor's patrimony in fraud of their rights, subject to the requisites and subsidiary character of the remedy.
These auxiliary remedies do not make the creditor the owner of the debtor's property. They preserve or recover value for satisfaction of the credit through lawful processes and only within the limits necessary to protect the creditor's enforceable claim.
Transmissibility of Rights
Rights acquired by virtue of an obligation are generally transmissible. The creditor's right may pass by assignment, succession, subrogation, merger, or other lawful mode, and the debtor's obligations may bind the estate to the extent allowed by law.
Transmissibility yields to contrary law, stipulation, or the nature of the obligation. Rights to support, obligations founded on special personal confidence, strictly personal services, and rights or duties inseparable from a person's status or qualifications may be non-transmissible.
A stipulation against assignment is generally respected between the parties when it is lawful. Even when assignment is restricted, the underlying credit may still have consequences between assignor and assignee depending on the wording of the restriction, the debtor's consent, and applicable law.
The death of a party does not automatically extinguish every obligation. Property obligations ordinarily pass to the estate, while obligations requiring personal performance, personal trust, or personal qualifications may be extinguished because performance by another would not be the prestation contemplated.
Integrated Effects of Nonperformance
The nature and effects rules treat obligations as part of the debtor's patrimonial responsibility. The creditor is not limited to asking politely for performance; the creditor may invoke legal compulsion, substitute performance, damages, preservation of the debtor's patrimony, and transmission of credit rights when the law allows.
The debtor's liability depends on the prestation, the source and terms of the obligation, the standard of care required, the presence or absence of demand, the existence of fraud or negligence, and whether a fortuitous event legally excuses performance.
Performance remains the central effect of every obligation. Damages, substitute performance, undoing, presumptions on payment, auxiliary remedies, and transmissibility are secondary legal consequences designed to protect the creditor's right while keeping enforcement within the limits of law, equity, and the nature of the prestation.
