Federal Act
on the Amendment of the Swiss Civil Code
(Part Five: The Code of Obligations)

¹ The form of a de­clar­a­tion on a bill of ex­change is de­term­ined ac­cord­ing to the law of the coun­try in whose ter­rit­ory the de­clar­a­tion was signed.

² However, where a de­clar­a­tion on a bill of ex­change that is in­val­id un­der the pre­vi­ous para­graph would be val­id un­der the law of the coun­try in whose ter­rit­ory a sub­sequent de­clar­a­tion is signed, the valid­ity of the later de­clar­a­tion is not af­fected by any form­al de­fects of the earli­er de­clar­a­tion.

³ Sim­il­arly, a de­clar­a­tion on a bill of ex­change giv­en by one Swiss na­tion­al abroad is val­id in re­la­tion to an­oth­er Swiss na­tion­al in Switzer­land provided it sat­is­fies the form­al re­quire­ments laid down by Swiss law.
