Contractual Obligation to Transfer Property Title and Breach of Unilateral Promise

The dispute concerned a contractual obligation where one party claimed the other failed to fulfill their promise to transfer title to a property by a specific date, leading to a request for contract rescission and damages. The court upheld the lower court's decision, reasoning that when a formal promise to sell is made, the unilateral declaration by the promisor, even if conditional, constitutes an irrevocable unilateral legal act that binds them to sell if the promisee exercises the option to purchase within the stipulated time, meaning the promisor's subsequent refusal or failure to execute the final deed constituted a breach justifying the rescission sought by the promisee.
