Swiss Civil Code

¹ A dis­in­her­it­ance is val­id only if the test­at­or in­dic­ates the reas­on for the dis­in­her­it­ance in his or her test­a­ment­ary dis­pos­i­tion.

² If the dis­in­her­ited per­son chal­lenges the dis­in­her­it­ance on the grounds that the reas­on there­for is in­cor­rect, any heir or leg­atee wish­ing to be­ne­fit from the dis­in­her­it­ance must prove that the reas­on is cor­rect.

³ Where no such proof may be ad­duced or no reas­on for the dis­in­her­it­ance is in­dic­ated, the dis­pos­i­tion shall be up­held in­so­far as it does not de­prive the dis­in­her­ited per­son of his or her stat­utory en­ti­tle­ment un­less it was made by the test­at­or in ob­vi­ous er­ror re­gard­ing the reas­on for the dis­in­her­it­ance.
