Cap. 16 Art. 1476Warranty.

(1) The assignor of a debt or any other right is bound to warrant its existence at the time of the assignment, although no express stipulation of warranty has been made in the assignment.

(2) If the debt does not exist, the assignor is bound to return the price received, unless the warranty as to the existence of the debt has been negatived either by a declaration of the assignor that he was making the assignment without any warranty, or by other words to that effect.
