Family Code, Art. 148

In cases of cohabitation not falling under the preceding Article, only the properties acquired by both of the parties through their actual joint contribution of money, property, or industry shall be owned by them in common in proportion to their respective contributions. In the absence of proof to the contrary, their contributions and corresponding shares are presumed to be equal. The same rule and presumption shall apply to joint deposits of money and evidences of credit. If one of the parties is validly married to another, his or her share in the co-ownership shall accrue to the absolute community or conjugal partnership existing in such valid marriage. If the party who acted in bad faith is not validly married to another, his or her shall be forfeited in the manner provided in the last paragraph of the preceding Article. The foregoing rules on forfeiture shall likewise apply even if both parties are in bad faith. (144a)
