1. The seller may withhold the subject matter of the sale until they receive the price due to them, even if the purchaser has offered a pledge or a guarantee. 2. If the subject matter of the sale perishes while in the seller's possession while they are withholding it, the loss shall be borne by the purchaser, unless the perishing was caused by the act of the seller. 3. If the seller agrees to defer the price, their right to withhold the subject matter of the sale shall be forfeited, and they shall be obliged to deliver it to the purchaser.
