A decree of nullity of civil marriage, if pronounced during the lifetime of the parties, shall be conclusive evidence of the invalidity of the marriage in all courts and proceedings. If such decree is pronounced after the death of either of the parties to the civil marriage, it shall be conclusive only as against the parties in the action and those claiming under them. (Amended 2009, No. 3, § 12a, eff. Sept. 1, 2009.)
