A marriage contracted by any person during the subsistence of a previous marriage shall be null and void, unless before the celebration of the subsequent marriage, the prior spouse had been absent for four (4) consecutive years and the spouse present had a well-founded belief that the absent spouse was already dead. In case of disappearance, where there is danger of death under the circumstances set forth in the provision of Article 391 of the Civil Code, an absence of only two years shall be sufficient.
