Buot vs. Court of Appeals

A contract to sell is distinguished from a contract of sale by the reservation of title in the vendor until full payment of the purchase price, which constitutes a positive suspensive condition, the non-fulfillment of which prevents the obligation from acquiring obligatory force and precludes reconveyance.

Spouses Alfredo and Susana Buot entered into a Memorandum of Agreement with Encarnacion Diaz Vda. de Reston for the purchase of the eastern portion of her property (19,042 square meters) in Minglanilla, Cebu. The agreement stipulated that the Buots would pay P19,042.00, beginning with P1,000.00 as earnest money and the balance within six months of notification that the certificate of title was ready for transfer. Crucially, the agreement provided that title, ownership, possession, and enjoyment would remain with Encarnacion until the full consideration was received and acknowledged. The Buots paid the earnest money and subsequently remitted additional sums totaling P2,774.00. Encarnacion, claiming financial distress and the Buots' lack of intent to consummate the sale, eventually sold the entire property to spouses Mariano and Sotera Del Rosario. Del Rosario secured a free patent title over the land after Encarnacion waived her prior application in his favor.

• The Memorandum of Agreement: On December 6, 1974, Encarnacion Diaz Vda. de Reston and spouses Alfredo and Susana Buot executed a Memorandum of Agreement for the sale of the eastern portion of Encarnacion's land (19,042 sq.m.) for P19,042.00. The Buots paid P1,000.00 as earnest money upon execution. The balance was payable within six months from notification that the title was ready for transfer. The agreement expressly stipulated that title, ownership, possession, and enjoyment would remain with the vendor until the full purchase price was received and acknowledged in a separate document.
• Partial Payments and Protective Measures: From April 1975 to March 1977, the Buots gave Encarnacion additional amounts totaling P2,774.00, receipted as part payment of the lot. Alfredo Buot also wrote to the Provincial and Municipal Assessors to annotate his rights on the tax declaration, which was annotated effective 1975.
• Encarnacion's Financial Distress and Rescission Efforts: Encarnacion claimed the Buots' advances were insufficient to cover registration expenses and that the Buots had no intention to buy, merely dealing with other interested buyers for profit. She pleaded with them to exercise their option or accept reimbursement, which they refused. She sought the intervention of the Philippine Constabulary to compel them to purchase the property.
• The Sale to Del Rosario: On May 17, 1977, Encarnacion mortgaged the entire property to Mariano Del Rosario, who subsequently purchased it on August 5, 1977 for P40,000.00 (though an accompanying affidavit stated the true consideration was P100,000.00, with P20,000.00 paid and an P80,000.00 balance). Del Rosario relied on Encarnacion's representations of ownership and her pending application for registration of title.
• Procurement of Free Patent Title: Del Rosario discovered that the Solicitor General had opposed Encarnacion's registration application because the property was public land. Advised by a Special Attorney to apply for a free patent, Del Rosario filed an application. Encarnacion waived her rights in his favor and withdrew her own registration case. On December 27, 1977, Del Rosario's free patent was approved, and Original Certificate of Title No. 0-15255 was issued in his name.
• Subsequent Litigation: The Buots sued for cancellation of Del Rosario's title and reconveyance, alleging fraud. Encarnacion filed a cross-claim against Del Rosario for the unpaid P80,000.00 balance of the purchase price.

• Nature of the Contract: Petitioners argued that the Memorandum of Agreement was a valid and partially executed contract of sale, not an option to purchase. Perfection was established by the agreement on the object and price, evidenced by the P1,000.00 downpayment.
• Validity of Second Sale: Because a contract of sale was perfected, the property could no longer be the valid subject of another sales contract in favor of Mariano Del Rosario, regardless of his alleged good faith.
• Qualifications for Patent: Del Rosario possessed no right over the land and was therefore unqualified to apply for a free patent.
• Implied Trust: Since the land properly belonged to Alfredo Buot, Del Rosario should be considered a trustee of the land for Buot's benefit under an implied trust.

• Nature of the Contract: Respondent Encarnacion countered that the agreement was merely an option to buy, requiring the Buots to furnish amounts for land registration, and that any consummated sale would be reflected in another instrument. The Buots' payments were insufficient, evidencing lack of intent to purchase.
• Laches and Bar: Because the Buots refused reimbursement despite unwillingness to consummate the sale, they had no cause of action and were barred by laches.
• Lack of Fraud: Respondent Del Rosario maintained that fraud in securing the free patent was not proven. He relied on Encarnacion's representations of ownership and followed legal advice to apply for a free patent after discovering the land was public. No opposition was filed by the Buots during his application.

• Nature of the Agreement: Whether the Memorandum of Agreement between the Buots and Encarnacion constitutes a contract of sale, an option to purchase, or a contract to sell.
• Right to Reconveyance: Whether petitioners are entitled to recover the property based on the nature of the contract and allegations of fraud against Del Rosario.
• Unjust Enrichment: Whether petitioners are entitled to the return of their partial payments despite the dismissal of their action for reconveyance.

• Nature of the Agreement: The Memorandum of Agreement was determined to be a contract to sell. The explicit reservation of title, ownership, possession, and enjoyment in the vendor until full payment constitutes a positive suspensive condition. The absence of a specific duration for the option negated its classification as an option contract. In a contract to sell, title does not pass to the vendee upon execution or delivery; full payment is the suspensive condition that triggers the transfer.
• Right to Reconveyance: Reconveyance was properly denied. Because the suspensive condition of full payment was not fulfilled, no actual sale transpired, and no title passed to the Buots. The failure to pay was not a breach of obligation but an event that prevented the obligation from acquiring obligatory force. Furthermore, the allegation that Del Rosario obtained the free patent title through fraud was unsupported by clear and sufficient evidence, fraud being a presumption that must be proven affirmatively.
• Unjust Enrichment: Petitioners are entitled to recover their partial payments. Under Article 1188 of the Civil Code, a debtor may recover what has been paid in expectancy of a suspensive condition that was not fulfilled. Retaining the P3,774.00 paid by the Buots would result in unjust enrichment on the part of Encarnacion and her heirs.

• Contract to Sell vs. Contract of Sale — In a contract to sell, the vendor reserves ownership and title until full payment of the purchase price, which acts as a positive suspensive condition. Unlike a contract of sale where title passes upon delivery, non-payment in a contract to sell is not a breach but an event that prevents the obligation from arising.
• Unjust Enrichment in Suspensive Conditions — Under Article 1188 of the Civil Code, if a suspensive condition is not fulfilled, the debtor may recover payments made by mistake or in expectancy of the condition happening, to prevent the creditor from being unjustly enriched at the debtor's expense.

• "In a contract to sell, the title over the subject property is transferred to the vendee only upon the full payment of the stipulated consideration. Unlike in a contract of sale, the title in a contract to sell does not pass to the vendee upon the execution of the agreement or the Delivery of the thing sold."
• "[S]uch payment being a positive suspensive condition, the failure of which is not considered a breach, casual or serious, but simply an event which prevented the obligation from acquiring obligatory force."

• Valarao vs. Court of Appeals, 304 SCRA 155 (1999) — Followed. Cited for the doctrine that in a contract to sell, full payment is a suspensive condition, and title is reserved by the vendor until such payment is made.
• Laforteza v. Machuca, G.R. No. 137552 (2000) — Followed. Cited for the definition of an option as a privilege to buy or sell within an agreed time, distinguishing it from the agreement in the present case which lacked a specific duration.
• Quezon Development Bank vs. Court of Appeals, 300 SCRA 206 (1998) — Applied. Cited for the rule that a party who has not appealed cannot seek affirmative relief other than what is provided in the judgment appealed from, barring the heirs of Encarnacion from claiming the entire property despite their prayer.

• Article 1188, Civil Code of the Philippines — Applied to justify the return of partial payments. The second paragraph provides that "The debtor may recover what during the same time he has paid by mistake in case of a suspensive condition," preventing unjust enrichment when the condition fails.
• Act 496 (Land Registration Act) — Referenced as the law under which Encarnacion initially filed her application for registration of title, which she later withdrew in favor of Del Rosario's free patent application.
