Bacala vs. Heirs of Spouses Poliño and Rom

Gross inadequacy of price does not invalidate a contract of sale unless simulation or lack of true consent is proven by clear and convincing evidence; a contemporaneous agreement providing that breach of conditions regarding usufruct and support shall render the sale "non-effective and nugatory" converts the transaction into a sale subject to a resolutory condition, not a donation mortis causa requiring testamentary formalities.

Anecito Poliño and his wife Clara owned an 80,003-square-meter coconut land in Cocomon, Lupon, Davao Oriental, registered under Transfer Certificate of Title No. T-3353. They were survived by two mentally incapacitated sons, Aquilino and Ducepino. Anecito's siblings included Aproniana Poliño Balisalisa and Juan Poliño. Clara predeceased Anecito in 1987; Anecito died in 1994. Prior to Anecito's death, he executed a Deed of Sale in favor of Juan dated April 13, 1992, conveying the subject property for P15,000.00, significantly below its assessed value.

• The Property and Parties: Anecito Poliño and Clara O. Poliño were registered owners of an 80,003-square-meter coconut land in Cocomon, Lupon, Davao Oriental, covered by TCT No. T-3353. They had two mentally incapacitated sons, Aquilino and Ducepino, who were their sole heirs. Anecito's siblings included Aproniana Poliño Balisalisa and Juan Poliño.
• The Sale Transaction: On April 13, 1992, Anecito executed a Deed of Sale in favor of Juan for the subject property for a stated consideration of P15,000.00. Simultaneously, the parties executed an Agreement stipulating that (1) Anecito shall retain usufruct over the property during his lifetime, and (2) upon Anecito's death, Juan shall support and provide financial assistance to Aquilino and Ducepino. The Agreement further provided that breach of these terms would render the Deed of Sale "non-effective and nugatory."
• Subsequent Events: Clara died on November 18, 1987, and Anecito died on November 21, 1994. On June 6, 1996, Aproniana was appointed judicial guardian of Aquilino and Ducepino. While the guardianship proceedings were pending, Juan executed a Deed of Voluntary Transfer on February 23, 1996, conveying the subject property to his children (Ruben, Brendo, Carlito, and Randy Poliño).
• The Complaint: On September 3, 1996, Aproniana instituted a complaint against Juan and Corazon (Juan's wife) seeking nullification of the Deed of Sale and Agreement on grounds that they were fictitious, without consideration, and constituted an invalid donation mortis causa. She alleged that no money was actually paid and that the P15,000.00 price was grossly inadequate compared to the property's market value of approximately P300,000.00. She also claimed Juan failed to support the incompetent siblings, causing Ducepino's death.
• Trial Court Proceedings: Aproniana testified that Anecito told her the sale was simulated and that no money was paid. Juan testified that he paid P15,000.00 and that Anecito surrendered the title to him. The RTC gave credence to Aproniana's testimony, noting Juan's failure to rebut the allegation of lack of consideration, and declared the documents void.
• Appellate Proceedings: The CA reversed, applying the presumption of consideration under Article 1354 of the Civil Code and holding that gross inadequacy of price does not invalidate a sale. It ruled that the Agreement was valid and that even if construed as a donation, it was an onerous donation governed by contract rules.

• Lack of Consideration and Simulation: Petitioner maintained that the Deed of Sale was void for lack of true consideration, relying on Aproniana's testimony that Anecito admitted no money was actually paid. He argued that Juan's failure to rebut this testimony constituted an admission by silence, and that the P15,000.00 price—grossly inadequate compared to the property's market value (P300,000.00) and tax declaration value (P150,000.00)—rendered the sale fictitious and simulated.
• Donation Mortis Causa: Petitioner contended that the transaction was actually a donation mortis causa disguised as a sale, evidenced by the reservation of usufruct to Anecito during his lifetime and the condition that Juan support the incompetent heirs after Anecito's death. As such, it failed to comply with the formalities of a will under Articles 804, 805, and 806 of the Civil Code and was void.
• Breach of Resolutory Conditions: Petitioner asserted that Juan failed to comply with the conditions in the Agreement—namely, providing usufruct to Anecito and supporting Aquilino and Ducepino—thus triggering the resolutory condition rendering the sale non-effective and nugatory.

• Presumption of Regularity and Consideration: Respondent countered that the Deed of Sale was a notarized document enjoying full faith and credit and the presumption of regularity under the Rules of Court. Clear and convincing proof is required to overturn this presumption. Article 1354 of the Civil Code presumes the existence of consideration in contracts, and this presumption stands absent clear and convincing evidence to the contrary.
• Nature as Valid Sale: Respondent maintained that the transaction was a valid contract of sale, not a donation, as the Deed clearly stated a price and there was no proof of animus donandi. The simultaneous Agreement merely imposed obligations on the vendee but did not change the nature of the contract. Alternatively, even if the Agreement were treated as a donation, it was an onerous donation governed by contract rules, not testamentary formalities.
• Failure to Prove Breach: Respondent argued that petitioner failed to prove by preponderant evidence that Juan breached the conditions of the Agreement, specifically that Anecito was deprived of usufruct or that Juan failed to support Aquilino and Ducepino after Anecito's death.

• Gross Inadequacy of Price: Whether gross inadequacy of the stated price invalidates the Deed of Sale.
• Nature of Transaction: Whether the transaction between Anecito and Juan was a sale subject to a resolutory condition or a void donation mortis causa.
• Validity and Breach: Whether the Deed of Sale and Agreement are valid and whether the conditions therein were breached to warrant rescission.

• Gross Inadequacy of Price: Gross inadequacy of price does not invalidate a contract of sale under Articles 1470 and 1471 of the Civil Code. The Deed of Sale stated a price of P15,000.00, and Anecito acknowledged receipt thereof. Notarized documents enjoy presumption of regularity and existence of consideration under Article 1354, requiring clear and convincing proof to overturn. Bare allegations and uncorroborated hearsay testimony (Aproniana's claim that Anecito told her no money was paid) cannot overcome the parol evidence rule or these legal presumptions. Simulation and inadequacy are incompatible grounds—if actual consideration exists, however inadequate, the transaction cannot be deemed simulated.
• Nature of Transaction: The transaction was a contract of sale subject to a resolutory condition, not a donation mortis causa. The Deed of Sale contained all elements of a valid sale: consent, determinate subject matter, and price certain. The simultaneous Agreement, which provided that breach of the conditions (usufruct to Anecito and support to the incompetent heirs) would render the sale "non-effective and nugatory," constituted a resolutory condition under Article 1191 of the Civil Code. The stipulations were clear and unambiguous; thus, the plain meaning rule applied, precluding extrinsic evidence to vary the terms. There was no evidence of animus donandi necessary for a donation, and the presence of consideration negates the element of liberality.
• Validity and Breach: While the Agreement provided for automatic rescission upon breach, the petitioner failed to prove by preponderant evidence that Juan actually breached the conditions. No concrete evidence showed that Anecito was deprived of usufruct during his lifetime or that Juan failed to support Aquilino and Ducepino after Anecito's death. Allegations of neglect causing Ducepino's death remained unsubstantiated. Consequently, the resolutory condition was not triggered, and the Deed of Sale and Agreement remain valid.

• Presumption of Consideration and Regularity of Notarized Documents — Contracts enjoy the presumption of existence of lawful consideration under Article 1354 of the Civil Code, and notarized documents are entitled to full faith and credit on their face as prima facie evidence of the facts stated therein. Clear and convincing proof is required to overturn these presumptions.
• Gross Inadequacy of Price — Under Articles 1470 and 1471 of the Civil Code, gross inadequacy of price does not affect a contract of sale unless it indicates a defect in consent or that the parties really intended a donation or some other act. Inadequacy and simulation are mutually exclusive allegations; if any consideration exists, the transaction cannot be deemed simulated.
• Parol Evidence Rule — When the terms of an agreement have been reduced to writing, it is considered as containing all the terms agreed upon, and no evidence of terms other than the contents of the written agreement is admissible between the parties to vary the terms (Section 10, Rule 130, Rules of Court).
• Plain Meaning and Four Corners Rules — Where the language of a contract is plain and unambiguous, its meaning must be determined from the language alone without reference to extrinsic facts; courts cannot rewrite contracts to make them more equitable or impose terms not agreed upon (Article 1370, Civil Code).
• Sale Subject to Resolutory Condition — A contract of sale may be subject to a resolutory condition, the fulfillment of which extinguishes the obligation. Where the contract itself provides for automatic rescission upon breach, judicial intervention is not required, but the breach must still be proven by the party alleging it.
• Donation vs. Sale — Donation requires animus donandi (intent to do an act of liberality) and entails a reduction of the donor's patrimony without consideration. The presence of a price, even inadequate, negates donation and indicates a contract of sale.

• "Gross inadequacy or simulation of price neither affects nor invalidates a sale, but it can be shown that the parties may have really intended a donation or some other act or contract."
• "The parol evidence rule forbids any addition to or contradiction of the terms of a written instrument by testimony or other evidence purporting to show that, at or before the execution of the parties' written agreement, other or different terms were agreed upon by the parties, varying the purport of the written contract."
• "A contract is the law between the parties and the best evidence of their intention. To preserve the constitutional liberties of contract, the courts ordinarily desist from interfering with the prerogatives of the consenting parties."
• "However, one cannot question a contract of sale for being simulated and at the same time assail the same for having a grossly inadequate consideration... If there exists an actual consideration for transfer evidenced by the alleged act of sale, no matter how inadequate it be, the transaction could not be a simulated sale."
• "Substantial breaches of contract are fundamental violations as would defeat the very object of the parties in making the agreement. The happening of a resolutory condition is a substantial breach that may give either party thereto the option to bring an action to rescind the contract and/or seek damages."
