Upholding Contract Validity Against Claims of Forgery and Incapacity in Property Sales

In a 2017 decision, the Supreme Court affirmed that a notarized deed of sale enjoys a strong presumption of regularity, and that parties challenging such documents on grounds of forgery, mental incapacity, or undue influence must present clear, convincing, and conclusive evidence to overcome it. The case of Almeda v. Heirs of Ponciano Almeda (G.R. No. 194189) illustrates the heavy burden placed on heirs who seek to nullify a family property sale long after its execution.

The Case Background

Spouses Venancio and Leonila Almeda, then aged 80 and 81, executed a Power of Attorney in 1976 authorizing their eldest son, Ponciano, to sell certain parcels of land in Tagaytay City covered by Original Certificates of Title. In 1978, a Deed of Absolute Sale was executed transferring the remaining properties to Ponciano for a consideration of over P700,000.

After both parents died, several of their children filed a complaint seeking to nullify the 1978 deed. They claimed that their parents' signatures were forged, that their parents were mentally incapacitated due to old age, that Ponciano exerted undue influence, and that the sale was simulated with inadequate consideration. The trial court dismissed the complaint, and the Court of Appeals affirmed. The Supreme Court upheld these rulings.

The Presumption of Regularity for Notarized Documents

The Court emphasized that a notarized deed of sale carries the evidentiary weight of due execution and authenticity. It is admissible without further proof and is entitled to full faith and credit on its face. To overturn this presumption, the party challenging the document must present strong, complete, and conclusive proof of its falsity or nullity. Mere preponderance of evidence is insufficient for a notarized document.

Proving Forgery Requires More Than Allegations

The petitioners relied primarily on the testimony of one heir, Emerlina, who gave uncertain and contradictory statements about whether her parents actually signed the deed. At one point she claimed the signatures were forged; at another, she said her parents may have signed without understanding the document; and later, she admitted she could not say whether the signatures were genuine.

The Court reiterated that forgery cannot be presumed. To establish forgery, a party must demonstrate the extent, kind, and significance of the variation between genuine and disputed signatures. The variation must be due to a different personality, not merely the natural variation found in the same writer's handwriting. Mere visual differences or "wild strokes" are insufficient.

Significantly, the Court conducted its own visual comparison of the disputed signatures against admittedly genuine signatures on the 1976 Power of Attorney. It found prominent similarities indicating the habitual writing of both spouses, with apparent differences attributable to their advanced age.

Age and Forgetfulness Do Not Equal Incapacity

The petitioners argued that their parents were "forgetful," of advanced age, and "at times" sickly. The Court rejected this, holding that mere forgetfulness, without evidence that it deprived a person of the ability to intelligently protect property rights, does not incapacitate a person from contracting.

The law presumes every person is competent to enter into contracts. The party claiming incapacity must prove it with clear and convincing evidence, ideally supported by medical evidence. The Court distinguished this case from Domingo v. CA, where the seller was shown to be senile, playing with her waste and urinating in bed. No similar circumstances existed here.

Undue Influence and Inadequate Consideration

The petitioners' general allegation that Ponciano took advantage of his position as eldest child was insufficient. Undue influence must be established by full, clear, and convincing evidence showing how the influencer deprived the other party of reasonable freedom of choice.

Similarly, the claim of unconscionable consideration failed. The Court noted that comparing a 1992 sale price of one lot to a 1978 sale of multiple properties was flawed, given the fourteen-year gap and differing market conditions.

Practical Takeaways

• Notarized documents enjoy a strong presumption of regularity and due execution that is difficult to overcome.
• Allegations of forgery require clear, positive, and convincing evidence, including expert testimony or documents for signature comparison.
• Advanced age or forgetfulness alone does not establish mental incapacity to contract; medical evidence is typically needed.
• Claims of undue influence must be supported by specific facts showing how consent was vitiated.
• Parties challenging a document must rely on the strength of their own evidence, not on the opponent's failure to present a defense.
