Pre-Trial Stipulations and Signature Authentication: Heirs of Salud v. Rural Bank of Salinas

In Heirs of Corazon Afable Salud v. Rural Bank of Salinas, Inc. (G.R. No. 202756, April 6, 2016), the Supreme Court addressed two important questions: whether parties are strictly bound by pre-trial stipulations to abide by an expert's findings, and how courts should weigh handwriting expert opinions against direct testimony in signature disputes. The ruling provides useful guidance for litigants and practitioners on the limits of expert evidence and the value of stipulations.

The Case: A Disputed Signature on a Special Power of Attorney

Corazon Afable Salud owned a property in Rosario, Cavite. In 1996, her daughter Carmencita obtained a loan from the Rural Bank of Salinas secured by a mortgage over the property. The bank relied on a Special Power of Attorney (SPA) dated August 20, 1996, purportedly signed by Corazon, authorizing Carmencita to use the property as collateral.

After Corazon died in 1998, her heirs—led by Deogracias Salud—discovered the mortgage and filed a case to nullify it, claiming Corazon's signature on the SPA was forged. During pre-trial, the parties agreed that the sole issue was whether the signature was genuine, and that the findings of a National Bureau of Investigation (NBI) handwriting expert would be "binding upon them."

The NBI examiner concluded the questioned signature was not written by the same person as the standard samples. However, during cross-examination, she admitted that one of the bank's sample signatures (Exhibit "5-A") could have been written by the same person who signed the SPA. The bank's president testified he personally saw Corazon sign the document, and the notary public confirmed she appeared before him for notarization.

The Ruling: Stipulations Do Not Compel Courts

The Supreme Court denied the heirs' petition and affirmed the Court of Appeals' decision upholding the SPA's validity. The Court held that while parties may agree to be bound by an expert's findings, courts are not compelled to adopt those findings. Judicial independence requires courts to assess all evidence, and a stipulation cannot surrender that duty.

The Court also clarified that expert opinions on handwriting are merely persuasive, not conclusive. Under Section 22, Rule 132 of the Rules of Court, handwriting may be proved through various means: a witness who saw the person write, a witness familiar with the handwriting, comparison by the court, or expert evidence. No single method is preferred over others.

Why the Expert's Report Was Not Enough

The NBI report lost its persuasive force because the examiner herself admitted the questioned signature and the bank's sample "could have been written by one and the same person." She also acknowledged that age and health conditions—Corazon was 77 at the time—can alter a person's handwriting without indicating forgery.

Against this inconclusive expert opinion, the Court weighed the direct testimonies of the bank president and the notary public, both of whom testified that Corazon personally appeared and signed. Their accounts were deemed straightforward and credible, especially since Corazon was physically present at the bank on the date in question—making any forgery unnecessary.

Practical Takeaways

• Pre-trial stipulations are binding on the parties, but they cannot compel a court to accept conclusions that conflict with other credible evidence. Courts retain the power to evaluate all evidence independently.
• Handwriting expert opinions are persuasive, not conclusive. A party relying solely on an expert report risks losing if the expert's findings are inconsistent or qualified during cross-examination.
• Direct testimony from eyewitnesses can outweigh expert opinions. Courts may credit a credible witness who personally saw a document signed over a scientific analysis, especially when the expert's conclusions are uncertain.
• Notarized documents enjoy a presumption of regularity. To overcome this presumption, a party must present clear and convincing evidence of forgery or irregularity.
• Age and health can affect handwriting. Minor differences between a questioned signature and known samples do not automatically prove forgery.
