(1) To any person whose former husband or wife has been absent, at the time of the second marriage, for five successive years without being known to such person, within that time, to be living; or
(2) To any person whose former marriage has been annulled or dissolved at the time of the second marriage, by the judgment of a competent court; or
(3) To any person who has, at the time of the second marriage, a reasonable and honest belief that his or her former husband or wife is dead, or that a valid divorce or annulment has been secured, or that his or her former marriage was invalid.
Whoever commits the crime of bigamy shall be fined not more than one thousand dollars, or imprisoned, with or without hard labor, for not more than five years, or both.
