New Mexico Statutes Chapter 40. Domestic Affairs § 40-3-13. Transfers, conveyances, mortgages and leases of real property; when joinder required

A. Except for purchase-money mortgages and except as otherwise provided in this subsection, the spouses must join in all transfers, conveyances or mortgages or contracts to transfer, convey or mortgage any interest in community real property and separate real property owned by the spouses as cotenants in joint tenancy or tenancy in common. The spouses must join in all leases of community real property or separate real property owned by the spouses as cotenants in joint tenancy or tenancy in common if the initial term of the lease, together with any option or extension contained in the lease or provided for contemporaneously, exceeds five years or if the lease is for an indefinite term.

Any transfer, conveyance, mortgage or lease or contract to transfer, convey, mortgage or lease any interest in the community real property or in separate real property owned by the spouses as cotenants in joint tenancy or tenancy in common attempted to be made by either spouse alone in violation of the provisions of this section shall be void and of no effect, except that either spouse may transfer, convey, mortgage or lease directly to the other without the other joining therein.

Except as provided in this section, either spouse may transfer, convey, mortgage or lease separate real property without the other's joinder.

B. Nothing in this section shall affect the right of one of the spouses to transfer, convey, mortgage or lease or contract to transfer, convey, mortgage or lease any community real property or separate real property owned by the spouses as cotenants in joint tenancy or tenancy in common without the joinder of the other spouse, pursuant to a validly executed and recorded power of attorney as provided in Section 47-1-7 NMSA 1978. Nothing in this section shall affect the right of a spouse not joined in a transfer, conveyance, mortgage, lease or contract to validate an instrument at any time by a ratification in writing.
