Swiss Civil Code

¹ A claim in abate­ment pre­scribes one year after the date on which the heirs learned of the in­fringe­ment of their rights and in any event after ten years have elapsed since the suc­ces­sion, in the case of test­a­ment­ary dis­pos­i­tion, or since the test­at­or’s death, in the case of oth­er dis­pos­i­tions.

² If the de­clar­a­tion of the in­valid­ity of a later dis­pos­i­tion re­vives an earli­er one, the pre­script­ive peri­ods be­gin on the date on which in­valid­ity was de­clared.

³ The en­ti­tle­ment to abate­ment may be in­voked as a de­fence at any time.
