(1) A person is guilty of bigamy if he intentionally marries or purports to marry another person when either person has a living spouse.

     (b) A court had entered a judgment purporting to terminate or annul any prior disqualifying marriage and the actor did not know that such judgment was invalid; or

     (c) The actor reasonably believed that he was legally eligible to marry.

     (3) The limitation imposed by RCW 9A.04.080 on commencing a prosecution for bigamy does not begin to run until the death of the prior or subsequent spouse of the actor or until a court enters a judgment terminating or annulling the prior or subsequent marriage.

     (4) Bigamy is a class C felony.
