Article 1529

The unpaid seller of goods loses his lien thereon:

(1) When he delivers the goods to a carrier or other bailee for the purpose of transmission to the buyer without reserving the ownership in the goods or the right to the possession thereof;

(2) When the buyer or his agent lawfully obtains possession of the goods;

(3) By waiver thereof.

The unpaid seller of goods, having a lien thereon, does not lose his lien by reason only that he has obtained judgment or decree for the price of the goods. (n)
