You think a prenup means you are planning to fail. You assume only the wealthy need one, and that asking for it is the same as not trusting your partner.
A prenup is not a bet against your marriage. It is a clear, honest plan that protects both of you if life does not go as expected.
Whether you are engaged or already married, Genus Law Group can help you put the right agreement in place in New Mexico.

What Is a Prenuptial Agreement?
A prenuptial agreement is a written contract two people sign before marriage that decides how property and finances will be handled if they divorce or one of them dies. People call it a prenup.
In New Mexico, prenups are governed by the Uniform Premarital Agreement Act, NMSA 1978 §§ 40-3A-1 through 40-3A-10. The agreement becomes effective the moment you marry.
New Mexico is a community property state, which means most assets earned during marriage are split equally in a divorce. A prenup lets you change those default rules and define what stays separate.
A prenup is useful if you own a business, have children from a prior relationship, are bringing significant assets into the marriage, or simply want clarity instead of guesswork later.

What Is a Postnuptial Agreement, and How Is It Different?
A postnuptial agreement does the same job as a prenup, but you sign it after you are already married. The terms cover property, debt, and what happens if the marriage ends.
Couples turn to a postnup when circumstances change. A new business, an inheritance, a career shift, or rebuilding trust after a rough patch are all common reasons to put one in place.
New Mexico law treats postnups differently from prenups. They are not covered by the Uniform Premarital Agreement Act, so courts review them closely for fairness and full financial disclosure between spouses.
Because spouses already owe each other a duty of good faith, a postnup must be especially honest and balanced to hold up. That is where careful drafting matters most.

What Can and Cannot Go in a Prenup or Postnup in New Mexico?
You can decide almost anything about property and finances, but you cannot use these agreements to limit child support, child custody, or a spouse's basic right to support. New Mexico law draws a firm line there.
Under NMSA 1978 § 40-3A-4, a prenup in New Mexico can address matters such as:
- How property either spouse owns now or acquires later is divided
- What stays separate property and what becomes community property
- How assets are handled at divorce, separation, or death
- Wills, trusts, and life insurance arrangements that carry out the agreement
- Which state's law governs the agreement
New Mexico law also sets clear limits. Under NMSA 1978 § 40-3A-4(B), an agreement cannot adversely affect a child's right to support, a spouse's right to support, child custody or visitation, where a spouse lives, or a spouse's freedom to pursue a career.
If your situation also involves children or support questions, learn more about child custody in New Mexico so your agreement does not overreach into areas a court controls.
When Is a Prenup or Postnup Enforceable in New Mexico?
A New Mexico court will enforce the agreement only if it was signed voluntarily, in writing, and with honest financial disclosure on both sides. Cutting corners on any of these can void it.
Under NMSA 1978 § 40-3A-3, a premarital agreement must be in writing, signed by both parties, and acknowledged. It does not require any payment or consideration to be valid.
A New Mexico court can refuse to enforce a prenup if the spouse fighting it proves they did not sign voluntarily, or that the agreement was unconscionable and they were not given a fair and reasonable disclosure of the other spouse's finances.
This is why pressure, hidden assets, and signing the night before the wedding are dangerous. The stronger the disclosure and the more time each person had to review it, the more likely the agreement survives a challenge.
Disputes over these agreements are heard in district court. In Albuquerque, that is the Second Judicial District Court.
