Contractual Promise to Sell and Transfer of Ownership Under Condition Precedent

A litigant challenged a lower court's decision concerning the legal status of a contract for the sale of property, arguing that the initial promise to sell, which was subject to a condition precedent, constituted a definitive transfer of ownership upon fulfillment of that condition. The Court of Cassation rejected the appeal, reasoning that a promise to sell, even when stipulated as definitive upon the satisfaction of a condition, does not transfer ownership until the condition is met, as the contract remains executory until that point, and the formal transfer requires the definitive fulfillment of the stipulated terms.
