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

¹ Un­less oth­er­wise agreed at the out­set or by sub­sequent amend­ment, the amount for which a surety who is a nat­ur­al per­son is li­able de­creases every year by three per cent or, where the claim is se­cured by mort­gage, by one per cent of the ori­gin­al max­im­um li­ab­il­ity. In all cases where the surety is a nat­ur­al per­son, the amount de­creases in at least the same pro­por­tion as the ob­lig­a­tion.

² This does not ap­ply to con­tracts of surety in fa­vour of the Con­fed­er­a­tion or its pub­lic in­sti­tu­tions or in fa­vour of a can­ton for the per­form­ance pub­lic law ob­lig­a­tions such as cus­toms du­ties, taxes and the like, and for freight charges, or to con­tracts of surety for the per­form­ance of of­fi­cial and civil ser­vice ob­lig­a­tions or for ob­lig­a­tions of vari­able amount, such as cur­rent ac­counts and con­tracts for de­liv­ery by in­stal­ments, and for peri­od­ic, re­cur­rent ob­lig­a­tions.
