I. Introduction and Purpose of Memo
This memorandum provides a surgical analysis of compensation as a mode of extinguishing obligations under the Philippine Civil Code. It distills the statutory requisites, judicial interpretations, and practical applications to guide in determining when mutual debts are automatically extinguished to the concurrent amount, absent a valid defense or exception.
II. Legal Foundation and Definition
Compensation is governed by Articles 1278 to 1290 of the Civil Code. Article 1278 defines it as the extinguishment of the debts of two persons who are reciprocally creditors and debtors of each other. It operates by operation of law (ex lege) at the moment the requisites concur, meaning it takes effect ipso jure even without the consent or knowledge of the parties, unless expressly waived.
III. Essential Requisites for Legal Compensation
Under Article 1279, five requisites must concur: (1) That each one of the obligors be bound principally, and that he be at the same time a principal creditor of the other; (2) That both debts consist in a sum of money, or if the things due are consumable, they be of the same kind, and also of the same quality if the latter has been stated; (3) That the two debts be due; (4) That they be liquidated and demandable; and (5) That over neither of them there be any retention or controversy, commenced by third persons and communicated in due time to the debtor. The absence of any single requisite bars legal compensation.
IV. Key Element: Liquidity of the Debts
“Liquidated” under the fourth requisite means the debt is already ascertained or readily ascertainable by mere mathematical calculation, without the need for a lengthy or complex evidentiary hearing. An unliquidated claim, such as one for moral damages or an unquantified breach, cannot be subject to legal compensation. This is the most frequently litigated requisite.
V. Distinction: Legal vs. Conventional Compensation
Legal compensation occurs automatically by law. Conventional compensation (Art. 1280) arises from an agreement of the parties, which may extinguish debts even if not all legal requisites are present (e.g., compromising on unliquidated claims). This is essentially a form of novation or compromise.
VI. Exceptions and Prohibitions
Compensation is not permitted in specific instances (Arts. 1287-1288): (1) Against deposits made in good faith with a bank or third persons; (2) Against claims for support due by gratuitous title; (3) Against obligations arising from tort (culpa aquiliana); (4) When one debt arises from a fiduciary relation (e.g., agent’s duty to return property); and (5) When attached property of a third party is in possession of the debtor, and the creditor has made a timely claim.
VII. Effects of Compensation
Upon the concurrence of all requisites, compensation extinguishes both debts to the concurrent amount from the moment they coexisted (Art. 1290). If the amounts are unequal, the larger debt is merely reduced, and the balance remains demandable. Interest on the extinguished portion ceases to run from the date of concurrence.
VIII. Waiver and Estoppel
The right to invoke legal compensation can be waived expressly or impliedly (e.g., by making a separate payment or acknowledging the debt without raising the offset). A party who fails to plead compensation in their answer may be deemed to have waived it, as it is a defense that must be timely asserted.
IX. Practical Remedies
In litigation, promptly plead compensation as an affirmative defense with specificity, detailing the opposing liquidated and demandable debt. For transactional practice, draft clear set-off agreements (conventional compensation) to avoid disputes over liquidity. Prior to suit, send a formal notice of offset to the counterparty, establishing the date of intended extinguishment and preserving the defense. When facing a claim, immediately audit all transactions with the claimant to identify potential reciprocal debts; if a potential offset is unliquidated (e.g., a claim for defects), initiate a separate action or arbitration to liquidate it, then amend pleadings to assert compensation. In collections, scrutinize the debtor’s counterclaim for liquidity; if it is clearly unliquidated, move to strike the defense of compensation as legally insufficient. Always verify that neither debt falls under the statutory exceptions, particularly those involving fiduciary duties or third-party claims.
