Diampoc vs. Buenaventura

A sale of real property is valid between the parties even if notarization is absent or defective; a defect in notarization merely strips the document of its public character and reduces it to a private instrument, the validity of which is established by preponderance of evidence. A party who signs a contract is presumed to know its contents and cannot escape its binding effect by alleging ignorance of the terms, having been grossly negligent in failing to read or have the document read before signing.

Petitioner Norma M. Diampoc and her husband Wilbur L. Diampoc owned a 174-square meter parcel of land in Signal Village, Taguig City, covered by Transfer Certificate of Title No. 25044. Respondent Jessie Buenaventura, a friend of the spouses, requested to borrow the owner’s duplicate copy of the title to use as collateral for a ₱1 million bank loan, promising to give the Diampocs ₱300,000 from the loan proceeds. The Diampocs agreed on the condition that Buenaventura would not sell the property. In early July 2000, Buenaventura presented a folded document to the spouses for signature, which they signed without reading. The document was later discovered to be a Deed of Sale conveying an 87-square meter portion of the land to Buenaventura for a stated consideration of ₱200,000. The Diampocs claimed they never appeared before the notary public and never received any payment. They filed a complaint to annul the deed, recover the duplicate title, and obtain damages.

• Nature of the Action: The Diampoc spouses filed a complaint for annulment of a Deed of Sale, recovery of the owner’s duplicate copy of TCT No. 25044, cancellation of the annotation of the sale on the title, and damages, alleging that the deed was obtained through fraud and deceit.

• The Alleged Loan Agreement: In May 2000, respondent Buenaventura, a friend of the spouses, asked to borrow the owner’s duplicate copy of TCT No. 25044 to use as security for a ₱1 million bank loan she intended to obtain for her store. It was agreed that Buenaventura would give the Diampocs ₱300,000 from the loan proceeds for the repair of their second floor, representing payment for the use of the title, and that she would repay the entire loan herself. The spouses acceded on the express condition that Buenaventura would not sell the property.

• Execution of the Deed: On July 3, 2000, while Norma Diampoc was at a store, Buenaventura approached her and had her sign a folded document without giving her the chance to read its contents. Wilbur Diampoc likewise signed the document, claiming it was dark at the time. The spouses later discovered that the document was a Deed of Sale conveying an 87-square meter portion of the property to Buenaventura for a stated consideration of ₱200,000. The word “Vendor” was printed under their names. The deed bore a notarization dated July 6, 2000, before Atty. Pastor Mendoza, but both Norma and Wilbur Diampoc maintained that they never appeared before the notary public and never received any consideration for the sale.

• Discovery and Complaint: In November 2002, an engineer went to the property to conduct a survey, advising the spouses that the land had been sold to Buenaventura and showing them the Deed of Sale. The Diampocs protested, brought the matter to the barangay for conciliation (which failed), and subsequently filed the instant civil case. They also filed criminal complaints for estafa, grave threat, coercion, and falsification against Buenaventura, which were dismissed.

• Respondent’s Version: Buenaventura claimed that the spouses Diampoc voluntarily sold her the 87-square meter portion of the land, as evidenced by the notarized Deed of Sale. She testified that she personally handed the ₱200,000 consideration to Norma Diampoc before they went to the notary public, and that the deed was signed and acknowledged before Atty. Pastor Mendoza. She argued that the case was a mere rehash of the dismissed estafa case and lacked merit.

• Lower Courts’ Findings: The RTC dismissed the complaint, finding that the notarized Deed of Sale was prima facie evidence of the facts stated therein and that the Diampocs failed to present clear and convincing evidence to overturn it. The RTC noted the spouses’ admission that they signed the document without reading it and that they were not illiterate. The CA affirmed, stressing that the Diampocs, being high school graduates, were bound by the contract they signed; their excuses—that the document was folded or that it was dark—were flimsy and indicated gross negligence. The CA held that a perfected contract of sale was established, with full consideration received, and that courts cannot extricate parties from their unwise agreements.

• Defective Notarization: Petitioner maintained that the Deed of Sale did not enjoy the presumption of regularity attached to notarized documents because it was not signed before the notary public; it was notarized in the absence of petitioner and her husband; only one Community Tax Certificate was used for both spouses; and respondent failed to present the notary public as a witness. These irregularities, she argued, negated the document’s public character and rendered the sale void.

• Lack of Valid Contract of Sale: Petitioner argued that a valid contract of sale did not arise because the essential requisites of consent, object, and consideration were absent. The spouses never intended to sell the property; their consent was obtained through fraud and deceit, as Buenaventura induced them to sign a folded document with the false assurance that it was merely an authorization for a bank loan. Furthermore, no consideration of ₱200,000 was ever paid; respondent presented no receipt or other proof of payment.

• Failure to Overcome Presumption: Because the notarization was irregular, petitioner asserted that the clear and convincing evidence standard normally required to overturn a notarized document should not apply, and that the preponderance of evidence standard should govern. She contended that the evidence of deception and lack of consideration met that standard, warranting annulment of the deed.

• Valid Notarized Sale: Respondent Buenaventura contended that the Deed of Sale was duly executed and acknowledged before a notary public, Atty. Pastor Mendoza, on July 6, 2000. The document was thus a public instrument entitled to the presumption of regularity. She insisted that the consideration of ₱200,000 was personally delivered to Norma Diampoc before the notarization.

• No Cause of Action: Respondent argued that the complaint was a rehash of an estafa case the Diampocs had previously filed against her, which had already been dismissed, and that the civil case was dismissible for lack of merit.

• Defective Notarization: Whether the irregularities in the notarization of the Deed of Sale rendered the sale void and deprived the document of its evidentiary weight.

• Validity of the Contract of Sale: Whether a perfected contract of sale existed between the parties, notwithstanding the Diampocs’ claim that they signed the document without reading it under the belief it was a loan authorization, and whether the payment of consideration was sufficiently established.

• Defective Notarization: The defective notarization did not invalidate the sale. The absence of notarization, or a defect therein, merely reduces a document to a private instrument, requiring proof of due execution and authenticity by preponderance of evidence rather than the clear and convincing standard attached to a duly-notarized document. Article 1358 of the Civil Code requires that contracts transmitting real rights over immovable property be in a public document, but failure to observe this form does not affect the validity or enforceability of the transaction between the parties; the requirement is for convenience and efficacy, not essential validity. Consequently, the Deed of Sale, as a private document, remained a binding agreement, and its validity was to be measured by the preponderance of evidence.

• Validity of the Contract of Sale: The lower courts’ unanimous conclusion that a valid contract of sale existed was affirmed. The Diampocs admitted signing the Deed of Sale. As high school graduates, they were literate and fully capable of reading the document before affixing their signatures; their excuses—that the document was folded and that it was dark—constituted gross negligence. The rule that a party who signs a contract is presumed to know its contents applies even to illiterate persons, who are expected to have the document read and explained to them. The Diampocs’ failure to take such ordinary precaution estopped them from avoiding the contract on the ground of ignorance. Moreover, the lower courts’ factual finding that the consideration of ₱200,000 was received in full was binding on the Supreme Court, which is not a trier of facts in a petition for review on certiorari. The Diampocs did not present clear and convincing evidence of fraud or deceit sufficient to overturn the written agreement.

• Effect of Defective Notarization — A defect in the notarization of a document strips it of its public character and reduces it to a private instrument. The clear and convincing evidentiary standard normally attached to a duly-notarized document is thereby dispensed with, and the measure to test its validity becomes preponderance of evidence. In this case, the Deed of Sale was treated as a private document, and its validity was assessed under the lower standard. The Diampocs nevertheless failed to meet their burden.

• Article 1358 Civil Code — Form Not Essential for Validity — Article 1358 requires that contracts transmitting or extinguishing real rights over immovable property be in a public document, but this formality is solely for convenience, greater efficacy, or to bind third persons. Failure to observe the prescribed form does not render the transaction invalid or unenforceable between the parties. A sale of real property, even if contained only in a private instrument or made orally, produces legal effects between the contracting parties.

• Presumption of Knowledge of Contract Contents — One who signs a contract is presumed to know its terms and cannot avoid enforcement by alleging ignorance of its contents. The rule applies with equal force to illiterate persons: if they are unable to read, they are negligent if they fail to have the contract read to them. Their failure to obtain a reading and explanation constitutes gross negligence that estops them from disowning the instrument. The Diampocs, who were literate high school graduates, were thus bound by the Deed of Sale they signed without reading, having been grossly negligent in not ascertaining its contents.

• Courts Will Not Relieve Parties from Unwise Contracts — The law will not relieve parties from the consequences of an unwise, foolish, or disastrous agreement entered into with all the required formalities and with full awareness of what they were doing. Courts have no power to extricate them from obligations voluntarily assumed simply because their contracts turn out to be disadvantageous. This principle reinforced the binding nature of the sale on the Diampocs, who could not avoid it merely because they later found the outcome unfavorable.

• “The absence of notarization of the deed of sale would not invalidate the transaction evidenced therein; it merely reduces the evidentiary value of a document to that of a private document, which requires proof of its due execution and authenticity to be admissible as evidence.” — This passage articulates the core procedural consequence of a notarization defect: the transaction survives as a private document subject to ordinary proof requirements.

• “A defective notarization will strip the document of its public character and reduce it to a private instrument. Consequently, when there is a defect in the notarization of a document, the clear and convincing evidentiary standard normally attached to a duly-notarized document is dispensed with, and the measure to test the validity of such document is preponderance of evidence.” — This excerpt precisely states the shift in the burden of proof that follows a defective notarization, a principle central to the Court’s refusal to annul the sale.

• “The rule that one who signs a contract is presumed to know its contents has been applied even to contracts of illiterate persons on the ground that if such persons are unable to read, they are negligent if they fail to have the contract read to them. If a person cannot read the instrument, it is as much his duty to procure some reliable persons to read and explain it to him, before he signs it, as it would be to read it before he signed it if he were able to do so and his failure to obtain a reading and explanation of it is such gross negligence as will estop him from avoiding it on the ground that he was ignorant of its contents.” — This classic formulation, drawn from Bernardo v. Court of Appeals, was the decisive ground for holding the Diampocs to the terms of the deed they signed without reading.

• “The law will not relieve parties from the effects of an unwise, foolish or disastrous agreement they entered into with all the required formalities and with full awareness of what they were doing. Courts have no power to relieve them from obligations they voluntarily assumed, simply because their contracts turn out to be disastrous deals or unwise investments.” — This declaration foreclosed any relief based on the alleged unfairness of the sale, reinforcing the sanctity of contractual undertakings.

• Mendoza v. Fermin, 738 Phil. 429 (2014) — Cited for the principle that defective notarization strips the document of its public character and changes the evidentiary standard to preponderance of evidence.

• Castillo v. Security Bank Corporation, 738 Phil. 145 (2014) — Relied upon for the interpretation of Article 1358 of the Civil Code, clarifying that the public instrument form is not essential for validity but only for convenience.

• Chong v. Court of Appeals, 554 Phil. 43 (2007) — Affirmed that a private conveyance of a house is valid between the parties even if not in a public instrument.

• Bernardo v. Court of Appeals, 387 Phil. 736 (2000), citing Mata v. Court of Appeals, 284 Phil. 36 (1992) — Provided the controlling doctrine that a signatory is presumed to know the contents of a contract and that negligence in failing to read or have the document read estops the signer from avoiding it.

• Fernandez v. Spouses Tan, 440 Phil. 334 (2002) — Cited for the principle that courts will not relieve parties from unwise or disastrous agreements voluntarily entered into.

• Article 1358, Civil Code — Requires that acts and contracts which have for their object the creation, transmission, modification or extinguishment of real rights over immovable property must appear in a public document. The Court held that this provision prescribes a form for convenience and greater efficacy, not for validity; its non-compliance does not affect the enforceability of the sale between the parties.

• Article 1159, Civil Code — Provides that obligations arising from contracts have the force of law between the contracting parties and must be complied with in good faith. The RTC invoked this article to underscore that the parties were bound by their contractual stipulations as embodied in the Deed of Sale.

Justices Teresita J. Leonardo-De Castro, Francis H. Jardeleza, and Noel Gimenez Tijam concurred. Chief Justice Maria Lourdes P.A. Sereno was on leave.
