Any marriage subsequently contracted by any person during the lifetime of the first spouse of such person with any person other than such first spouse shall be illegal and void from its performance, unless:
(1) The first marriage was annulled or dissolved; or
(2) The first spouse had been absent for seven consecutive years at the time of the second marriage without the spouse present having news of the absentee being alive, or if the absentee, though he has been absent for less than seven years, is generally considered as dead and believed to be so by the spouse present at the time of contracting such subsequent marriage, or if the absentee is presumed dead according to articles 390 and 391. The marriage so contracted shall be valid in any of the three cases until declared null and void by a competent court. (29a)
