Jacinto Uy Diño v. Hon. Court of Appeals

Summary

This case clarifies the scope and application of continuing suretyship agreements under Philippine Civil Law. Petitioners executed continuing suretyships in 1977 to guarantee their former employer's bank obligations. When the principal debtor obtained a new letter of credit in 1979 without the sureties' knowledge and subsequently defaulted, the bank sought to hold the sureties liable under their 1977 agreements. The Supreme Court established important precedents: (1) continuing suretyships cover future debts under Article 2053 of the Civil Code until formally revoked; (2) no notice to sureties is required for future transactions covered by continuing guaranties; (3) sureties remain liable only up to the specified limits in their agreements plus stipulated interest, fees and costs. The decision balances the protective policy toward sureties with the commercial necessity of continuing guaranties in banking transactions, providing clarity on the extent of surety liability in ongoing credit relationships.
