Article 457. The term of the obligation to transfer the goods.
1. The term for the seller to transfer the goods to the buyer is determined by the contract of sale, and if the contract does not allow to determine this period, in accordance with the rules provided for in Article 314 of this Code. 2. The contract of sale is deemed to be concluded with the condition of its execution by a strictly defined term, if it clearly follows from the contract that if the deadline for its fulfillment is violated, the buyer loses interest in the contract. The seller has the right to execute such an agreement before the occurrence or after the expiration of the term specified in it only with the consent of the buyer.
