Swiss Civil Code

¹ Where doc­u­ment­ary proof of in­form­a­tion con­cern­ing civil status is re­quired but is im­possible or un­reas­on­ably dif­fi­cult to ob­tain des­pite mak­ing reas­on­able ef­forts, the can­ton­al su­per­vis­ory au­thor­ity may ac­cept a de­clar­a­tion made in the pres­ence of the re­gis­trar as proof provided such in­form­a­tion is not dis­puted.

² The re­gis­trar shall re­mind any per­son mak­ing such a de­clar­a­tion of his or her duty to tell the truth and that a false de­clar­a­tion may lead to pro­sec­u­tion.
