Upholding Notarized Deeds: Supreme Court on Authenticity and Forgery in Property Sales

The Supreme Court has long held that a notarized document carries a presumption of authenticity and due execution. In Gatan v. Vinarao (G.R. No. 205912, October 18, 2017), the Court reiterated this principle in a dispute over a Deed of Absolute Sale, underscoring the heavy burden on parties who claim that a notarized deed was forged. The ruling is a practical reminder for property owners and buyers alike: a notarized deed is a powerful piece of evidence, and allegations of forgery must be supported by more than bare denials.

The Case: A Family Dispute Over Land

The petitioners, Rogelia Gatan and the heirs of her late husband Bernardino, sought to nullify a Deed of Absolute Sale dated December 30, 1989. The deed supposedly conveyed a portion of their property in Isabela to the respondents' predecessors. The petitioners claimed that Bernardino, who was allegedly illiterate, could not have signed the deed, and that Rogelia's signature was missing—instead, a certain "Aurelia Ramos Gatan" appeared in the space for marital consent.

The respondents, on the other hand, presented a witness who testified that he personally saw Bernardino and Rogelia sign the deed before a notary public. They also presented tax declarations and receipts showing that they had been paying real property taxes on the subject property for years.

The Issue: Factual Disputes and the Rule 45 Limitation

The petitioners raised a single issue: whether the Court of Appeals erred in upholding the validity of the deed. However, the Supreme Court noted that the core of the petitioners' argument—whether the signatures were forged—was a question of fact.

Under Rule 45 of the Rules of Court, a petition for review on certiorari is limited to questions of law. The Court is not a trier of facts and will not re-evaluate evidence already considered by the lower courts. While there are recognized exceptions to this rule, none applied in this case. The trial court's findings, affirmed by the Court of Appeals, were binding on the Supreme Court.

The Ruling: Presumption of Authenticity Stands

The Supreme Court denied the petition, affirming the validity of the Deed of Absolute Sale. The Court emphasized that a notarized contract enjoys a prima facie presumption of authenticity and due execution. To overturn this presumption, the party alleging forgery must present evidence that is "clear, convincing, and more than merely preponderant."

The petitioners failed to meet this burden. Their evidence consisted mainly of Rogelia's uncorroborated testimony that her husband was illiterate and could not sign his name. In contrast, the respondents presented an instrumental witness who testified that he was physically present when Bernardino and Rogelia signed the deed before the notary public.

The Court also noted that the petitioners did not present corroborating witnesses or an independent expert to prove that the signatures were forged. As the Court has held, "mere disclaimer is not sufficient" to disavow a signature on a public document.

The Rules on Proving Forgery

The decision reinforces two key evidentiary rules:

1. Forgery cannot be presumed. It must be proved by clear, positive, and convincing evidence. The burden lies on the party alleging forgery.
2. Genuineness of handwriting may be proved by any witness who saw the person sign the document, under Section 22 of Rule 132 of the Rules of Court.

In this case, the respondents' witness, who saw the execution of the deed, provided direct and positive testimony that outweighed the petitioners' bare denials.

Practical Takeaways

• A notarized deed is presumed genuine. If you are challenging a notarized document, you must present clear, convincing, and more than merely preponderant evidence to overcome this presumption.
• Bare denials are not enough. Claiming that a signature is forged without corroborating witnesses or expert testimony will likely fail.
• Witnesses who saw the signing matter. Testimony from someone who was present during the execution of a document can be decisive in proving its authenticity.
• Rule 45 is not for factual disputes. If your case hinges on factual questions, a petition for review with the Supreme Court may not be the proper remedy.
• Keep your documents in order. Tax declarations and receipts for property payments can strengthen your claim of ownership and possession.
