Compensation MONDRAGON PERSONAL SALES, INC. v. VICTORIANO S. SOLA, JR. G.R. no. 174882, January 21, 2013 Peralta, J. FactS: Petitioner Mondragon Personal Sales entered into a Contract of Services with respondent Sola whereby the latter would provide service facilities (bodega cum office) to petitioner’s products, sales force and customers for a consideration of commission or service fee which at a certain rate of the monthly sales of Mondragon. Prior to the execution of the said contract, respondent’s wife had an existing obligation with petitioner. Such obligation was acknowledged and confirmed by the respondent and made himself (with his wife) liable to pay such debt on installment basis. $y virtue of which, the petitioner withheld the payment of the respondent’s service fees and applied the same as partial payments to the debt which he obligated to pay. Thereafter, respondent closed and suspended the operation of his office cum bodega and subse&uently filed for an action for accounting and rescission against the petitioner. The RTC ruled in favor of the petitioner Mondragon and held that there was no fraud on the part of the latter that would rescind their contract and that it is correct when it deducted the service commission of Sola to his wife’s account. The CA reversed the RTC’s decision. ISSue: Whether legal compensation under Art. *+79 of the Civil Code would apply in this case. Hel*: Yes. The petitioner/s act of withholding respondent/s service fees0commissions and applying them to the latter/s outstanding obligation with the former is merely an acknowledgment of the legal compensation that occurred by operation of law between the parties. 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. 1egal compensation takes place by operation of law when all the re&uisites 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 re&uisites. 1egal compensation re&uires the concurrence of the following conditions2 (*) That each one of the obligors be bound principally, and that he be at the same time a principal creditor of the other3 (+) 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 &uality if the latter has been stated3 (4) That the two debts be due3 (5) That they be li&uidated and demandable3 (5) That over neither of them there be any retention or controversy, commenced by third persons and communicated in due time to the debtor. All the re&uisites for legal compensation are present in this case. Petitioner and respondent are both principal obligors and creditors of each other. Their debts to each other consist in a sum of money. Respondent acknowledged and bound himself to pay petitioner the amount of P*,974,*55.74 which was already due, while the service fees owing to respondent by petitioner become due every month. Respondent/s debt is li&uidated and demandable, and petitioner/s payments of service fees are li&uidated and demandable every month as they fall due. 7inally, there is no retention or controversy commenced by third persons over either of the debts. Thus, compensation is proper up to the concurrent amount where petitioner owes respondent P*+5,858.8* for service fees, while respondent owes petitioner P*,974,*55.74.
