Forged Signatures and Bank Liability: Upholding Due Diligence in Loan Transactions

---

Banks are expected to exercise extraordinary diligence in handling their clients' money. When a bank honors a forged check, the consequences can be severe—not just for the account holder, but for the bank itself. The Supreme Court's 2019 decision in Philippine National Bank v. Felina Giron-Roque (G.R. No. 240311) clarifies how far that duty extends and what happens when a bank fails to meet it.

The case involved a client whose property was foreclosed after a supposedly authorized withdrawal turned out to be based on a forged signature. The Court's ruling reaffirms that banks cannot simply pass the burden of fraud onto their customers.

The Facts of the Case

Felina Giron-Roque obtained a credit line from Philippine National Bank (PNB) in April 1995, secured by a real estate mortgage over her property. In February 1997, she availed of a ₱50,000 loan from this credit line.

While Felina was in the United States, a second loan of ₱120,000 was supposedly availed through her friend, Dr. Gloria Apostol. When Felina discovered that a check for ₱119,820 had been withdrawn from her account, she asked PNB to investigate.

Felina tendered ₱16,000 to fully pay her first loan, but PNB refused the payment, claiming it was insufficient to cover both loans. PNB then proceeded with the extrajudicial foreclosure of her property.

The Issue Before the Court

The central question was whether the extrajudicial foreclosure proceedings against Felina's property should be nullified, given that the second loan was based on a forged check.

The Court's Ruling

The Supreme Court denied PNB's petition and affirmed the nullification of the foreclosure, with a modification.

The Court upheld the factual findings of the lower courts: Felina did not avail of the second loan, her signature on the check was forged, Gloria was not authorized to withdraw, and PNB was remiss in its duty as a banking institution.

Because the second loan was void, Felina's outstanding balance was reduced to just the first loan—₱14,565.58 plus interests and penalties. The Court noted that Felina had already tried to settle this amount by tendering a cashier's check for ₱16,000, which PNB refused.

The Court gave Felina 60 days to settle her remaining obligation. The annulment of the foreclosure was made without prejudice to PNB's right to pursue proper remedies if she failed to pay.

The Standard of Diligence for Banks

The decision reinforces a well-established principle: banks are engaged in a business imbued with public interest. They must exercise extraordinary diligence in handling transactions involving their clients' funds.

When a bank allows a withdrawal based on a forged signature, it cannot simply claim good faith. The bank is expected to verify signatures and ensure that withdrawals are properly authorized. Failure to do so makes the bank liable for the resulting loss.

Practical Takeaways

• Banks bear the risk of forged checks. If a bank honors a check with a forged signature, it cannot recover the amount from the account holder who did not authorize the transaction.
• Extraordinary diligence is the standard. Ordinary care is not enough for banks. They must exercise the highest level of care because of the public trust reposed in them.
• A void loan cannot support a foreclosure. If the underlying loan is void due to forgery, any foreclosure based on that loan has no legal basis.
• Tender of payment matters. A borrower who attempts to settle an obligation in good faith—even if the bank refuses the payment—may be given an opportunity to pay rather than face immediate foreclosure.
• Banks should verify before they act. Before allowing withdrawals or encashing checks, banks must take reasonable steps to confirm the authenticity of signatures and the authority of the person presenting the check.
