Tan Shuy vs. Spouses Maulawin

A private document is sufficiently authenticated when witnesses familiar with the maker's handwriting identify it, and such documents can establish a dation in payment whereby a debtor's delivery of goods to a creditor offsets an outstanding monetary loan.

Petitioner Tan Shuy, engaged in buying copra and corn, extended a ₱420,000 loan to farmer-businessman Guillermo Maulawin on July 10, 1997. The written contract obligated Maulawin to sell lucad or copra to petitioner and pay the loan amount. From April 1998 to April 1999, Maulawin delivered copra and corn to petitioner, transactions recorded in receipts called "pesadas" prepared by petitioner's children.

• The Loan Contract: On July 10, 1997, petitioner lent respondent ₱420,000. The contract, written in Filipino, stated respondent received the amount and obligated himself to sell his lucad/copra to petitioner and pay the loan, with a clause consenting to court action if he failed.
• The Deliveries and the Pesadas: From April 1998 to April 1999, respondent delivered copra and corn to petitioner. Petitioner's daughter Elena, or occasionally his son Vicente, issued "pesadas" detailing the date, weight, trucking cost, and net price.
• The "pd" Notation: Petitioner's business practice dictated that a "pd" notation on the total purchase price meant the crop was paid in cash. Respondent presented pesadas without the "pd" notation to show that the net proceeds were not paid to him in cash but were instead applied as loan installments.
• Conflicting Claims: Petitioner claimed respondent only paid ₱28,500 in cash, leaving a ₱391,500 balance. Respondent claimed he fully paid the loan through copra deliveries worth ₱420,537.68, pointing to the pesadas without "pd" notations as proof of offsetting.

• Authentication of Private Documents: Petitioner argued that the pesadas were private documents that should not have been admitted in evidence without proper authentication.
• Fabrication: Petitioner contended that the pesadas were fabricated to falsely indicate that the goods delivered were copra rather than corn.
• Formal Offer Defects: Petitioner claimed that five of the pesadas mentioned in the formal offer of evidence were not actually offered.
• Separate Obligations: Petitioner maintained that the loan required cash payment and the contract did not specify that copra proceeds would offset the loan; thus, he could not be compelled to accept copra as payment.

• Full Payment via Dation: Respondent countered that he had fully paid the loan through copra deliveries, where the net proceeds were applied as installment payments.
• Evidentiary Weight of Pesadas: Respondent argued that the pesadas without "pd" notations proved the proceeds were not paid in cash to him but were applied to the loan, a fact authenticated by the testimony of petitioner's own children.

• Authentication of Private Documents: Whether the pesadas require authentication before they can be admitted in evidence.
• Dation in Payment: Whether the delivery of copra amounted to installment payments for the loan obtained by respondents from petitioner.

• Authentication of Private Documents: The pesadas were properly authenticated and admitted. Under Rule 132, Section 20 of the Rules of Court, the due execution and authenticity of a private document can be proved by anyone who saw it executed or by evidence of the genuineness of the maker's signature or handwriting. Petitioner's son, Vicente, confirmed the penmanship and handwriting of his sister Elena on the pesadas. Furthermore, petitioner was estopped from questioning the documents' authenticity because he failed to timely object and could have easily rebutted them by presenting Elena as a witness.
• Dation in Payment: The delivery of copra constituted dation in payment (dación en pago) under Article 1245 of the Civil Code. By delivering copra and allowing the net proceeds to be applied to the loan rather than receiving cash, respondent partially extinguished the obligation. However, because respondent himself testified that only copra proceeds—not corn proceeds—were intended as loan payments, the value of the corn deliveries (₱41,585.25) was deducted from the total delivery value, leaving an outstanding balance of ₱41,047.57.

• Dation in Payment (Dación en Pago) — When property is alienated to the creditor in satisfaction of a debt in money, the obligation is extinguished to the extent of the value of the thing delivered. The law on sales applies, as the creditor is effectively buying the debtor's property and charging the payment against the obligation. Here, the subsequent arrangement of applying copra delivery proceeds to the loan constituted dation in payment.
• Proof of Private Documents — Before a private document offered as authentic is received in evidence, its due execution and authenticity must be proved either by anyone who saw the document executed or by evidence of the genuineness of the signature or handwriting of the maker. Here, the testimony of the maker's brother identifying her handwriting satisfied this requirement.

• "Here, the debtor delivers and transmits to the creditor the former’s ownership over a thing as an accepted equivalent of the payment or performance of an outstanding debt. In such cases, Article 1245 provides that the law on sales shall apply, since the undertaking really partakes – in one sense – of the nature of sale; that is, the creditor is really buying the thing or property of the debtor, the payment for which is to be charged against the debtor’s obligation."
• "As found by the CA, Tan Shuy 'could have easily belied the existence of x x x the pesadas or receipts, and the purposes for which they were offered in evidence by simply presenting his daughter, Elena Tan Shuy, but no effort to do so was actually done by the former given that scenario.' The pesadas having been admitted in evidence, with petitioner failing to timely object thereto, these documents are already deemed sufficient proof of the facts contained therein."

• Lopez v. Court of Appeals, G.R. No. L-33157, 29 June 1982 — Cited for the rule that dation in payment extinguishes the obligation to the extent of the value of the thing delivered, unless the parties consider the thing as equivalent to the obligation.
• Aquintey v. Tibong, G.R. No. 166704, 20 December 2006 — Followed for the principle that in dation in payment, the law on sales applies.
• Obando v. People, G.R. No. 138696, 7 July 2010 — Followed for the proposition that failure to timely object to the admission of documents renders them sufficient proof of the facts contained therein.

• Article 1232, Civil Code — Provides that an obligation is extinguished by payment or performance. Applied to hold that the delivery of copra constituted payment.
• Article 1245, Civil Code — Governs dation in payment, providing that the law on sales shall apply. Applied to characterize the arrangement where copra proceeds offset the loan.
• Rule 132, Section 20, Rules of Court — Prescribes the methods for proving the due execution and authenticity of a private document. Applied to hold that the pesadas were properly authenticated by the testimony of a witness familiar with the maker's handwriting.
