Only the endorser who is the right holder pursuant to substantive law can cross (cancel) the endorsement. In principle, endorser executes this transaction over his/ her own endorsement. Crossing (cancellation) of other endorsements by the endorser is possible only for the simplification transactions, permitted by Art. 272(2) of Commercial Code, in the course of the exercise of application rights. The endorser must execute this crossing (cancellation) transaction by indicating the will of avoidance or alteration of the transaction according to Art. 207 of Code of Civil Procedure, and by approving with his/her initials. By this way, the endorser can cancel the endorsement completely or partially. Atypical crossings (if they are actual cancellations) made through crossing out, erasure or scratch of the endorsement are invalid as long as they are not approved by the right holder’s signature; they create a break in the chain of endorsements. The crossing of endorsement by unauthorized persons constitutes offenses of forgery or falsification of official documents (Art. 204 and 206 of Turkish Criminal Code).
