Jose Vaca v. Manuel Kosca

Summary

Jose Vaca sued Manuel Kosca to collect debts totaling P1,985.91 arising from Kosca's purchase of the M. Kosca & Co. partnership. When Kosca bought the business in February 1912, he assumed all assets and liabilities, including Vaca's loans and surety payments. Kosca later attempted to transfer the business to Jose Infante, but this second contract failed because Infante could not provide required bondsmen. The Supreme Court reversed the lower court's dismissal, holding that the failed transfer contract did not release Kosca from his original obligations. The decision establishes important precedent on contract formation, assumption of liabilities in business transfers, and the requirements for valid novation under the Civil Code. The court emphasized that conditional contracts require fulfillment of all conditions and that mere projected agreements cannot override validly executed contracts.
