Corporate Liability vs Personal Guarantee: Surety Agreements in the Philippines

The Supreme Court's 1997 ruling in Aguenza v. Metropolitan Bank & Trust Co. (G.R. No. 74336) clarifies a crucial distinction in Philippine corporate and contract law: when a corporate officer signs a continuing surety agreement, that personal guarantee does not automatically extend to every loan taken by other officers, especially if the corporation itself never authorized the debt. The case offers practical guidance for business owners, corporate officers, and lenders on the limits of surety agreements.

The Facts of the Case

In 1977, the Board of Directors of Intertrade & Marketing Co., Inc. authorized its President, J. Antonio Aguenza, and Executive Vice-President, Vitaliado Arrieta, to jointly apply for credit lines with Metropolitan Bank & Trust Company (Metrobank). Pursuant to this authority, both men executed a Continuing Suretyship Agreement binding themselves jointly and severally with Intertrade to pay the bank any obligation the corporation incurred, up to P750,000.00.

The trust receipts covered by this agreement were fully paid. However, in March 1978, Arrieta and Lilia Perez, a bookkeeper of Intertrade, obtained a separate P500,000.00 loan from Metrobank, signing a promissory note in their own names. When they defaulted, Metrobank sought to hold Aguenza liable under the continuing surety agreement, arguing that the loan was a corporate obligation of Intertrade.

The Core Issue

The central question was whether the P500,000.00 loan obtained by Arrieta and Perez was a corporate liability of Intertrade, and if so, whether Aguenza's continuing surety agreement covered it. The Court of Appeals ruled against Aguenza, but the Supreme Court reversed.

The Supreme Court's Ruling

The Supreme Court held that Aguenza was not liable. Three key principles guided the decision:

First, the loan was not a corporate obligation. The Court found no evidence that Intertrade's Board of Directors authorized Arrieta and Perez to contract the loan. Under Article 1878 of the New Civil Code, borrowing money requires a special power of attorney. The Court emphasized that a corporation's power to borrow must be exercised through its Board of Directors or officers with proper authority. Since Arrieta acted alone—without Aguenza's participation—and no board resolution existed, the loan was the personal obligation of Arrieta and Perez.

Second, a judicial admission by counsel does not bind a corporation without proper authority. The Court of Appeals relied on an "admission" in Intertrade's answer to conclude the loan was corporate liability. The Supreme Court rejected this, noting that an admission made by counsel "without any enabling act or attendant ratification of corporate act" does not bind the corporation. Ratification must come from the Board of Directors or the governing body with authority to make the contract.

Third, a surety agreement is strictly construed against the creditor. The Court cited Article 2055 of the New Civil Code: a contract of surety is never presumed and cannot extend to more than what is stipulated. Since the disputed loan was not Intertrade's obligation, it fell outside the scope of the continuing surety agreement.

The Continuing Surety Agreement Point

Notably, the Court did not dispute that the agreement was "continuing" in nature—meaning it covered obligations arising after its execution until formally revoked in writing. However, the scope of that coverage was limited to obligations of Intertrade, not personal loans of individual officers. A continuing surety agreement does not expand to cover debts the corporation never incurred.

Practical Takeaways

• Corporate officers should ensure that any loan they sign for a corporation is backed by a board resolution or proper authorization. Without it, the loan may be treated as a personal obligation, and a surety agreement covering corporate debts will not apply.
• Lenders should verify corporate authority before extending credit. Requiring a board resolution or special power of attorney protects the bank and prevents disputes over whether a loan is corporate or personal.
• A continuing surety agreement remains in force until revoked in writing. Officers who sign such agreements should formally revoke them when no longer needed.
• Surety agreements are strictly construed. Courts will not expand a surety's liability beyond the clear terms of the contract, especially when the underlying obligation belongs to individuals, not the corporation.
• Judicial admissions by corporate counsel may not bind the corporation unless properly authorized. Corporations should carefully review pleadings filed on their behalf.
