Burden of Proof in Bank Overdraft Claims: Security Bank v. Gan

---

When a bank sues a client to recover an alleged overdraft, who carries the burden of proving the debt? The Supreme Court's ruling in Security Bank and Trust Company v. Eric Gan (G.R. No. 150464, June 27, 2006) provides a clear answer: the bank must present competent evidence, and internal ledger entries are not enough when the person who made them had no personal knowledge of the transactions.

The case involved a dispute over a current account opened by Eric Gan with Security Bank in 1981. The bank claimed that Gan had a special arrangement with its branch manager allowing him to transfer funds from his account to another person's account before his deposited checks cleared. These transfers, covered by "debit memos," allegedly resulted in an overdraft that the bank sought to recover.

When Gan refused to pay, the bank filed a collection suit. Gan denied liability, insisting the alleged overdraft resulted from transactions made without his knowledge or consent. The trial court dismissed the complaint, and the Court of Appeals affirmed. The bank then elevated the case to the Supreme Court.

The Issue

The central question was whether the bank sufficiently proved that Gan knowingly incurred the overdraft. The bank relied primarily on ledger cards and the testimony of its bookkeeper, Patricio Mercado, who recorded the transactions. Mercado admitted he had no personal knowledge of the alleged special arrangement between Gan and the branch manager, Qui.

The Ruling

The Supreme Court denied the bank's petition, affirming the lower courts' dismissal of the complaint. The Court emphasized that factual findings of the trial court, especially when affirmed by the Court of Appeals, are conclusive on the Supreme Court when supported by the evidence on record.

The Court held that the ledger entries were not competent evidence to prove that Gan consented to the fund transfers. The entries merely showed that transfers were made and that Qui approved them—not that Gan authorized them. The bank's claim of a special arrangement was a bare allegation never substantiated by evidence.

Business Records Exception to Hearsay

The bank invoked the business records exception to the hearsay rule under the Rules of Court, which allows entries made in the course of business to be received as prima facie evidence under certain conditions. The Court identified these conditions: the entrant must be dead or unable to testify; the entries were made at or near the time of the transactions; the entrant was in a position to know the facts stated; the entries were made in a professional capacity or in performance of duty; and the entries were made in the ordinary course of business.

The ledger entries failed on at least two counts. Mercado, who prepared the entries, was available to testify, so there was no necessity for the exception. More importantly, he had no personal knowledge of the facts behind the entries—particularly the alleged transfers and the special arrangement. He merely recorded what his superior told him, making the entries hearsay.

The Court agreed with the trial court's observation that allowing ledgers prepared by the bank at its own instance to substitute for proof of agreements with third parties would set a dangerous precedent. Business entries are an exception to the hearsay rule only under strict conditions, which must be scrupulously observed to prevent them from being used as a source of undue advantage for the party preparing them.

Estoppel Argument Rejected

The bank also argued that Gan was estopped from denying the claim because he benefited from the special arrangement. The Court rejected this argument because the arrangement was never established, and there was no evidence that Gan benefited from it. In fact, the debit memos showed fund transfers from Gan's account to other accounts, not to his benefit.

Practical Takeaways

• Banks bear the burden of proof in collection suits for overdrafts. They must present competent evidence, not just internal records.
• Ledger entries alone are insufficient when the bookkeeper lacks personal knowledge of the underlying transactions. The business records exception to the hearsay rule requires strict compliance.
• Present the key witness. If a bank official allegedly arranged a special accommodation with a client, the bank should present that official or another witness with personal knowledge of the agreement.
• Document client agreements. Banks should reduce special arrangements to writing to avoid disputes over their existence and terms.
• Estoppel requires proof of benefit. A party cannot be estopped from denying a claim unless the opposing party proves the alleged benefit and reliance.
