Swiss Civil Code

¹ The debt­or may raise only such ob­jec­tions as arise from the entry in the land re­gister or to which he or she is per­son­ally en­titled with re­gard to the cred­it­or or to doc­u­ment of title in the case of a mort­gage cer­ti­fic­ate on pa­per.

² Agree­ments in­clud­ing an­cil­lary pro­vi­sions on the mort­gage cer­ti­fic­ate debt may only be cited in op­pos­i­tion to an ac­quirer of the mort­gage cer­ti­fic­ate act­ing in good faith if they are re­ferred to in the land re­gister and on the doc­u­ment of title in the case of a mort­gage cer­ti­fic­ate on pa­per.
