A dissolution of marriage or divorce may be granted in New Mexico divorce law for either no-fault or fault grounds.
The sole no-fault ground is incompatibility because of discord and conflicts of personalities such that the legitimate ends of the marriage relationship have been destroyed preventing any reasonable expectation of reconciliation.
Fault grounds include:
If the spouses have permanently separated and do not live together or cohabit, either spouse may begin proceedings for property division, child custody and support, and maintenance, without asking for a dissolution of marriage. One of the spouses must have been a resident of New Mexico for at least 6 months immediately preceding the filing for legal separation and have a home in New Mexico.
