Gerardo Villanueva v. St. Martin of Tours Kilusang Bayan Sa Pagpapautang

Summary

This case involves the judicial foreclosure of a chattel mortgage securing an unpaid loan. Gerardo Villanueva borrowed P135,000 from St. Martin of Tours Kilusang Bayan sa Pagpapautang, Inc., secured by a chattel mortgage on his Isuzu vehicle. When Villanueva failed to pay upon maturity in April 1996, the lending corporation filed for judicial foreclosure. Villanueva raised various defenses including lack of capacity to sue, absence of promissory note, and prematurity, but these were deemed waived for not being raised in his answer. All three court levels ruled in favor of the lender, holding that the corporation had capacity to sue, the loan obligation was sufficiently established through Villanueva's admissions, and the obligation matured upon demand under Civil Code Article 1179. The decision affirms the principle that contractual obligations are enforceable even without formal promissory notes when the debtor admits the obligation, and procedural defenses must be timely raised or be deemed waived.
