Bank Negligence Bars Recovery: Solutio Indebiti and Unjust Enrichment in Check Clearing Errors

The Supreme Court recently denied BDO Unibank's bid to recover PHP 76,000.00 that a depositor withdrew after the bank erroneously cleared a regional check as a local one. In BDO Unibank, Inc. v. Barcellano (G.R. No. 261264, February 12, 2026), the Court explained when the principles of solutio indebiti and unjust enrichment apply—and why they did not help the bank here. The ruling offers important lessons for banks and depositors alike.

The Facts

In September 2003, Cristina Barcellano deposited a PHP 151,200.00 regional check from a Landbank branch in Ligao City, Albay into her savings account at BDO's Lucena City branch. A BDO teller mistakenly validated the check as local instead of regional. This error shortened the clearing period from seven banking days to just three.

Because of the premature clearing, Barcellano withdrew PHP 76,000.00 from her account on September 23, 2003. The next day, the check was returned to BDO due to a stop payment order. The bank demanded the money back, but Barcellano refused. BDO then filed an estafa case against her.

The Regional Trial Court acquitted Barcellano, finding no fraud or deceit on her part. The Court of Appeals affirmed. BDO appealed to the Supreme Court, arguing that the erroneous crediting was a payment by mistake giving rise to a constructive trust under solutio indebiti (Article 2154, Civil Code) and that Barcellano's refusal to return the money constituted unjust enrichment (Article 22, Civil Code).

The Issue

The central question was whether BDO could recover the amount Barcellano withdrew, given that the bank's own negligence caused the premature clearing. BDO argued that Barcellano was unjustly enriched at the bank's expense.

The Ruling

The Supreme Court denied BDO's petition. The Court held that BDO's loss was caused by its own gross negligence, not by any mistake that would trigger solutio indebiti.

Solutio indebiti requires a genuine mistake. Under Article 2154 of the Civil Code, an obligation to return arises when something is received without right to demand it and was "unduly delivered through mistake." The Court clarified that this mistake must be an essential error of fact or a mistake in applying a doubtful question of law. Here, the teller's error was not a mere misunderstanding of banking rules—it was a failure to exercise the extraordinary diligence that banks owe their clients.

Gross negligence bars recovery. The Court identified multiple lapses by BDO: crediting the check without clearing it with the drawee bank, improperly classifying it as local instead of regional, and failing to detect the error until a stop payment order arrived. This constituted gross negligence—"the want of even slight care" with conscious indifference to consequences. Since the mistake arose from gross negligence, no recovery was due.

No unjust enrichment. The Court found that Barcellano did not knowingly receive a benefit to which she was not entitled. She deposited a check and withdrew funds that appeared in her account. She even attempted to withdraw the remaining balance, suggesting she believed in good faith that the funds were hers. The stop payment order's reason was never established, and there was no evidence her account had issues.

Civil liability after acquittal. The Court also addressed the procedural context. Under Rule 111, Section 2 of the Rules of Court and Article 29 of the Civil Code, an acquittal based on reasonable doubt does not automatically extinguish civil liability arising from sources other than the crime charged. However, since BDO could not prove any independent basis for recovery, the civil aspect also failed.

Practical Takeaways

• Banks bear extraordinary diligence. Financial institutions must observe the highest standard of care in handling checks and deposits. A bank that clears a check prematurely assumes the risk of loss.
• Solutio indebiti is not a catch-all. The principle applies only when payment is made through genuine mistake, not through negligence that falls short of ordinary prudence.
• Unjust enrichment requires knowledge. A recipient must knowingly retain a benefit to which they are not entitled. A depositor who withdraws funds that a bank erroneously credited may be protected by good faith.
• Acquittal does not end civil liability. A criminal acquittal based on reasonable doubt does not extinguish civil claims rooted in other sources of obligation—but the claimant must still prove those claims.
• Documentation matters. Banks should keep clear records of check classifications and clearing procedures to avoid disputes over their own errors.
