According to New Mexico divorce laws, a premarital agreement must be in writing, signed by both parties and acknowledged. A premarital agreement may not adversely affect the right of a child or spouse to support, a party's right to child custody or visitation, a party's choice of abode or a party's freedom to pursue career opportunities. It is not enforceable if the party against whom enforcement is sought proves that he or she did not execute the agreement voluntarily and the agreement was unconscionable when it was executed.
