La Yebana v. Julio L. Valenzuela

Summary

This case involves a suretyship dispute where Rufino Valenzuela served as surety for Julio L. Valenzuela's obligations as sales agent of La Yebana Co., Inc. under a P1,000 bond. When Julio incurred substantial debt, he provided additional mortgage security without the surety's knowledge. Rufino argued his obligations were extinguished by the creditor's acceptance of additional security and failure to take prompt action. The Supreme Court affirmed the lower court's judgment requiring joint and several payment, holding that the suretyship bond's express waiver clause prevented extinguishment of the surety's obligation regardless of additional securities or delay in enforcement. The decision reinforces the binding nature of contractual waivers in suretyship agreements and clarifies when surety obligations are extinguished under Civil Code provisions.
