Artikel 25

An acceptance is written on the bill of exchange. It is expressed by the word „accepted” or any other equivalent term. It is signed by the drawee. The simple signature of the drawee on the face of the bill constitutes an acceptance.
When the bill is payable at a certain time after sight, or when it must be presented for acceptance within a certain limit of time in accordance with a special stipulation, the acceptance must be dated as of the day when the acceptance is given, unless the holder requires that it shall be dated as of the day of presentment. If it is undated, the holder, in order to preserve his right of recourse against the endorsers and the drawer, must authenticate the omission by a protest drawn up within the proper time.
