Mondragon Personal Sales, Inc. vs. Sola, Jr.

Legal compensation operates by operation of law to extinguish mutual obligations to the concurrent amount when both parties are reciprocally principal debtors and creditors of each other, provided the five requisites under Article 1279 of the Civil Code concur: (1) each obligor is bound principally and is at the same time a principal creditor of the other; (2) both debts consist in a sum of money or consumables of the same kind and quality; (3) both debts are due; (4) both are liquidated and demandable; and (5) neither debt is subject to retention or controversy commenced by third persons.

Petitioner Mondragon Personal Sales, Inc., engaged in the sale of consumer products through sales representatives, contracted respondent Victoriano S. Sola, Jr. as a service contractor to provide bodega and office facilities in General Santos City. Prior to this arrangement, respondent's wife, Lina Sola, maintained a franchise distributorship with petitioner that generated an unpaid obligation. On January 26, 1995, respondent executed a letter addressed to petitioner's Vice-President for Finance acknowledging his wife's indebtedness of ₱1,973,154.73 and undertaking to pay the same on installment basis. Petitioner subsequently withheld respondent's service fees for February to April 1995, applying them as partial payment toward this assumed debt. On April 29, 1995, respondent closed and padlocked the bodega, ceasing operations.

• The Contract of Services: On October 2, 1994, petitioner and respondent entered into a three-year contract (until October 1, 1997) wherein respondent provided warehouse and office facilities in General Santos City for petitioner's products. Respondent was entitled to service fees computed as five percent (5%) of monthly sales up to ₱2.5 million, or fixed amounts for higher sales tiers.
• The Wife's Pre-existing Obligation: Prior to the contract, respondent's wife operated a franchise distributorship with petitioner that resulted in an unpaid balance.
• The January 26, 1995 Letter: Respondent wrote to petitioner's Vice-President for Finance acknowledging his wife's account of ₱3,463,173.88, confirming ₱1,973,154.73 as due, and undertaking to pay ₱100,000.00 by February 1, 1995, with the balance payable via monthly postdated checks of not less than ₱100,000.00. The letter concluded with: "I fully understand and voluntarily agree to the above undertaking with full knowledge of the consequences which may arise therefrom," and was signed by respondent alone.
• Withholding and Application: Petitioner withheld respondent's service fees for February, March, and April 1995 (totaling ₱125,040.01) and applied these as partial payment toward the acknowledged debt.
• Closure of Operations: On April 29, 1995, respondent closed and padlocked his bodega cum office, suspending operations to minimize alleged losses.
• Judicial Proceedings: Respondent filed suit for accounting and rescission, claiming petitioner unlawfully withheld service fees from October 1994 to April 1995 totaling ₱222,202.84. Petitioner counterclaimed for the balance of the assumed debt, delivery of padlocked merchandise, and other damages.

• Legal Compensation: Petitioner argued that the withholding of service fees and their application to respondent's outstanding obligation constituted legal compensation under Article 1279 of the Civil Code, as all requisites were present: both parties were principal obligors and creditors; the debts consisted of sums of money; both were due, liquidated, and demandable; and neither was subject to third-party retention.
• Assumption of Debt: Petitioner maintained that respondent's January 26, 1995 letter evidenced a clear intent to assume his wife's debt solidarily, making respondent a principal debtor to petitioner and thus susceptible to compensation.
• Rescission Improper: Petitioner contended that respondent was the first to breach the contract by unilaterally closing the bodega on April 29, 1995; consequently, respondent could not invoke Article 1191 to rescind the contract.
• Remand Unnecessary: Petitioner argued that the amount of withheld service fees (₱125,040.01) had already been established by the trial court and was not contested on appeal, rendering the CA's order for remand improper.
• Validity of Counterclaim: Petitioner asserted that respondent admitted the indebtedness in his letters dated January 26, 1995 and September 29, 1997, thus the trial court correctly awarded the balance of ₱1,543,643.96.

• Breach by Petitioner: Respondent argued that petitioner's act of unlawfully withholding service fees constituted a willful and deliberate breach of contractual obligations, entitling him to rescission under Article 1191 of the Civil Code.
• No Assumption of Obligation: Respondent maintained that he did not assume his wife's obligation solidarily; there was no novation or substitution of debtor, and his liability, if any, was only subsidiary as a spouse after exhaustion of conjugal partnership assets.
• No Legal Compensation: Respondent contended that no compensation could exist because he was not the principal debtor of the franchise obligation; his wife was. The debts were not mutual as they arose from different transactions.
• Remand Required: Respondent argued that remand was necessary to properly determine the exact amount of service fees unlawfully withheld by petitioner.

• Compensation: Whether legal compensation took place between petitioner's obligation to pay service fees and respondent's assumed obligation to pay his wife's debt.
• Assumption of Obligation: Whether respondent assumed his wife's debt solidarily or as co-debtor, thereby becoming a principal obligor to petitioner.
• Rescission: Whether respondent was entitled to rescind the Contract of Services under Article 1191 for alleged breach by petitioner.
• Remand: Whether the case should be remanded to the trial court for determination of the amount of withheld service fees.
• Counterclaim: Whether petitioner was entitled to its counterclaim for the balance of the assumed debt after offsetting the withheld service fees.

• Compensation: Legal compensation took place by operation of law. All requisites under Article 1279 were satisfied: petitioner and respondent were reciprocally principal creditors and debtors; both obligations consisted of sums of money; both were due; both were liquidated and demandable; and neither was subject to retention or controversy by third parties. The service fees (₱125,040.01) were properly applied to the assumed debt (₱1,973,154.73).
• Assumption of Obligation: Respondent became a co-debtor and solidarily bound himself to pay his wife's debt. The January 26, 1995 letter, particularly its concluding paragraph signed by respondent alone, manifested clear intent to assume the obligation as principal debtor, not merely as a guarantor or administrator of conjugal assets.
• Rescission: Rescission was improper. Because legal compensation operated automatically by law, petitioner did not breach the contract by withholding the service fees. Conversely, respondent breached first by closing the bodega on April 29, 1995; a party who first breaches cannot seek rescission under Article 1191.
• Remand: Remand was unnecessary. The amount of withheld service fees (₱125,040.01) had been established by the trial court and was not disputed on appeal; thus, no further determination was required.
• Counterclaim: Petitioner was entitled to the balance of ₱1,543,643.96, representing the assumed debt of ₱1,973,154.73 less the service fees applied by way of compensation (₱125,040.01) and other payments made, plus legal interest.

• Legal Compensation (Article 1279) — Compensation is a mode of extinguishing to the concurrent amount the obligations of persons who in their own right and as principals are reciprocally debtors and creditors of each other. Legal compensation takes place by operation of law when all the following requisites concur: (1) each one of the obligors is bound principally, and is at the same time a principal creditor of the other; (2) 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) the two debts are due; (4) they are liquidated and demandable; (5) over neither of them is there any retention or controversy commenced by third persons and communicated in due time to the debtor. The Court applied this doctrine to find that the service fees and the assumed debt mutually extinguished each other up to ₱125,040.01.
• Assumption of Debt vs. Novation — A party may bind himself solidarily to pay another's debt through a clear and unequivocal undertaking showing intent to become a principal co-debtor. Novation is never presumed; it requires clear intent to substitute a new debtor or extinguish the old obligation. Here, the letter showed respondent's intent to assume the debt solidarily, not to novate it.
• Rescission Under Article 1191 — Rescission of reciprocal obligations is available only to the injured party when the other fails to perform. The party who first breaches the contract cannot seek rescission; rather, the injured party may choose between specific performance or rescission with damages.

• "Compensation is a mode of extinguishing to the concurrent amount the obligations of persons who in their own right and as principals are reciprocally debtors and creditors of each other. Legal compensation takes place by operation of law when all the requisites are present, as opposed to conventional compensation which takes place when the parties agree to compensate their mutual obligations even in the absence of some requisites."
• "A reading of the letter shows that respondent becomes a co-debtor of his wife's accountabilities with petitioner. Notably, the last paragraph of his letter which states 'I fully understand and voluntarily agree to the above undertaking with full knowledge of the consequences which may arise therefrom' and which was signed by respondent alone, shows that he solidarily bound himself to pay such debt."
• "As legal compensation took place in this case, there is no basis for respondent to ask for rescission since he was the first to breach their contract when, on April 29, 1995, he suddenly closed and padlocked his bodega cum office in General Santos City occupied by petitioner."

• Bank of the Philippine Islands v. Court of Appeals, G.R. No. 142731, June 8, 2006 — Cited for the definition of compensation and the distinction between legal compensation (by operation of law) and conventional compensation (by agreement of parties).

• Article 1191, Civil Code — Provides for the right to rescind reciprocal obligations in case of breach by the other party.
• Article 1279, Civil Code — Enumerates the five requisites for legal compensation to take place by operation of law.
• Article 1381, Civil Code — Lists rescissible contracts based on lesion or fraud; distinguished from rescission under Article 1191 which applies to reciprocal obligations.
