The presence of dual signatures on a bill of exchange gives rise to different legal consequences. Commercial enterprise officials typically place two signatures on a bill of exchange when it is signed. The area containing the second signature on the bill of exchange directly affects the legal outcome. This second signature on the bill of exchange is the 2nd in some cases, the signature causes commercial companies to be responsible to the borrower by issuing a promissory note. The company becomes indebted with the signature placed on the company stamp. However, by signing a second signature outside the stamp, we can state that the company employee who issued the bond is personally the debtor of the promissory note.
In accordance with the decisions of the Court of Cassation, in order for the debtor’s liability to arise in the promissory note, the check, the promissory note and the bond must be signed by a single person. At this point, the signature found outside the company stamp has the quality of aval. In this case, the company official becomes personally indebted. It is not possible for both signatures to be placed on the stamp. In order for a personal responsibility to arise, it is necessary to sign an area other than the stamp.
Bills of exchange usually appear to us in a single signed form. According to the Turkish Commercial Code, the signature of the person issuing the promissory note must be included on the promissory note. Otherwise, the promissory note does not have validity in any way. Within the framework of the law, only the signature of the person issuing the promissory notes is required. However, when looking at the application, two are often encountered in bills of exchange. However, it is not possible to say that the promissory note containing two signatures is invalid. The presence of two signatures on the promissory note does not differentiate the result that will arise from the promissory note in any way. In other words, it is valid for single-signed promissory notes and double-signed promissory notes. However, as mentioned above, there are some basic features of double-signed promissory notes. It is possible for individuals to have a double signature on the promissory note in order to realize these features.
