Commentaries: Art. 1067

The custodian of the original bill must be indicated on the copy. The custodian is obliged to surrender the original bill to the rightful holder of the copy.
Where he refuses to surrender it, the holder has right of recourse against the endorsers of the copy and against persons who have appended a declaration of guarantee to it only after arranging for protest to be made, thereby confirming that the original bill was not surrendered to him on request.
Where the original bill bears the comment “henceforward endorsements valid only if made on copy” or a comment to that effect appended to the last endorsement before the copy was made, any subsequent endorsement added to the original bill is void.
