Personal Surety Liability vs Corporate Rights: When Banks Lose Their Claim

The Supreme Court's ruling in Spouses Toh v. Solid Bank Corporation (G.R. No. 154183, August 7, 2003) clarifies a critical distinction in Philippine civil law: when individuals sign a continuing guaranty for a corporation's debts, they are personally bound — but only within the precise terms of that agreement. The case also demonstrates that a creditor's failure to follow its own documented requirements can discharge those sureties entirely.

The Facts

Solid Bank Corporation extended a P10 million credit facility to First Business Paper Corporation (FBPC). As part of the arrangement, the bank required a Continuing Guaranty signed by the corporation's officers — spouses Luis and Vicky Tan Toh (petitioners) and spouses Kenneth and Ma. Victoria Ng Li (respondents). The petitioners were FBPC's Chairman and Vice-President at the time.

The "letter-advise" from the bank specified the documentary requirements, including that domestic letters of credit be supported by a 15% marginal deposit, extendible three times for 30 days each, subject to 25% partial payment per extension.

After the petitioners divested their shares and resigned from FBPC, the corporation defaulted on its obligations. The bank demanded payment from the petitioners as sureties, invoking the Continuing Guaranty.

The Issue

The central question was whether the petitioners, having signed the Continuing Guaranty in their personal capacities, remained liable for FBPC's debts even after they ceased to be officers and stockholders — and whether the bank's actions in extending the credit deadlines without following its own requirements discharged them from liability.

The Ruling

The Supreme Court held that the Continuing Guaranty was a valid and binding contract. The petitioners signed it in their personal capacities, not merely as corporate officers. As the Court noted, citing Garcia v. Court of Appeals (G.R. No. 80201, November 20, 1990), there is no law prohibiting a corporate officer from binding himself personally to answer for a corporate debt. The limited liability doctrine protects stockholders from corporate debts, but a person may voluntarily waive that protection.

However, the Court also ruled that the bank's unauthorized extensions of the letters of credit discharged the petitioners from liability. Under Article 2079 of the Civil Code, an extension granted to the debtor by the creditor without the consent of the guarantor extinguishes the guaranty. The bank's own witness admitted that extensions were made without the required marginal deposits and partial payments.

The Court also applied Article 2080 of the Civil Code, which releases guarantors when the creditor's acts prevent them from being subrogated to the creditor's rights. The bank's abandonment of attached properties and failure to preserve security for the debt further supported the discharge.

Practical Takeaways

• Personal vs. corporate capacity matters. When signing a surety or guaranty, specify whether the signature is in a personal or representative capacity. Courts will not presume a limited capacity absent clear language.
• A continuing guaranty survives resignation. Unless the agreement provides otherwise, a surety remains liable even after leaving the corporation. The surety must formally revoke the guaranty in writing and notify the creditor.
• Creditors must follow their own requirements. A bank cannot selectively apply the terms of a credit agreement. Deviating from documented prerequisites — such as required deposits or payment conditions — can release sureties.
• Surety contracts are interpreted strictly. Under Philippine law, any doubt on the terms of a surety agreement is resolved in favor of the surety, particularly for accommodation sureties who receive no benefit from the contract.
• Documentation is protection. Both creditors and sureties should maintain clear, written records of all credit terms, extensions, and waivers to avoid disputes over what was actually agreed.
