Civil Code, Art. 1526

Subject to the provisions of this Title, notwithstanding that the ownership in the goods may have passed to the buyer, the unpaid seller of goods, as such, has: (1) A lien on the goods or right to retain them for the price while he is in possession of them; (2) In case of the insolvency of the buyer, a right of stopping the goods in transitu after he has parted with the possession of them; (3) A right of resale as limited by this Title; (4) A right to rescind the sale as likewise limited by this Title. Where the ownership in the goods has not passed to the buyer, the unpaid seller has, in addition to his other remedies a right of withholding delivery similar to and coextensive with his rights of lien and stoppage in transitu where the ownership has passed to the buyer.
