Civil Code, Art. 1595

Where, under a contract of sale, the ownership of the goods has passed to the buyer and he wrongfully neglects or refuses to pay for the goods according to the terms of the contract of sale, the seller may maintain an action against him for the price of the goods. Where, under a contract of sale, the price is payable on a certain day, irrespective of delivery or of transfer of title and the buyer wrongfully neglects or refuses to pay such price, the seller may maintain an action for the price although the ownership in the goods has not passed. But it shall be a defense to such an action that the seller at any time before the judgment in such action has manifested an inability to perform the contract of sale on his part or an intention not to perform it. Although the ownership in the goods has not passed, if they cannot readily be resold for a reasonable price, and if the provisions of article 1596, fourth paragraph, are not applicable, the seller may offer to deliver the goods to the buyer, and, if the buyer refuses to receive them, may notify the buyer that the goods are thereafter held by the seller as bailee for the buyer. Thereafter the seller may treat the goods as the buyer's and may maintain an action for the price. (n)
