1. When it is expressly provided for in the marriage settlements (Arts 134 and 74, FC);
2. When it is so declared by a competent court (Art. 134, FC); and,
3. When the surviving spouse failed to liquidate the absolute community or conjugal partnership of gains of a previous marriage which has been terminated by death within the one-year period required by law prior to contracting another marriage. The subsequent marriage is mandatorily governed by a regime of complete separation. (Arts. 103 and 130, FC)
