Prenuptial Agreement in
New Mexico
New Mexico is a community property state that has also adopted the UPMAA, giving couples both a powerful reason to create a prenup and a modern legal framework for doing so. Under New Mexico's default rules, all income and property acquired during the marriage belongs equally to both spouses and is subject to a 50/50 division upon divorce — a prenuptial agreement is the primary tool for departing from that default. New Mexico is also notable for its significant number of couples who enter marriage with interests in mineral rights, oil and gas leases, and Native American cultural property, making precise asset classification especially important.

Best practices
Tips for a strong prenup in New Mexico
Following these best practices helps ensure your agreement is clear, fair, and enforceable.
New Mexico's community property rules are automatic at marriage — creating a prenup before the wedding is the only reliable way to protect premarital assets from becoming jointly owned.
If either partner has interests in oil and gas leases or mineral rights — common in southeastern New Mexico — describe them specifically in the prenup, including how royalty income during the marriage will be classified.
Attach a full financial disclosure schedule to the agreement with current valuations; New Mexico courts expect complete transparency about each party's financial position at signing.
Sign the prenup with meaningful time before the ceremony — courts are more confident in voluntary consent when there was no last-minute pressure, which matters especially in destination weddings in Santa Fe or Taos.
New Mexico's UPMAA framework allows modification of spousal support but permits courts to refuse enforcement if the result would be unconscionable — draft alimony provisions that would be fair even if circumstances change.
FAQ
Common questions about prenups in New Mexico
New Mexico is a community property state — what happens to income I earn during our marriage without a prenup?
Under New Mexico law, wages and income earned by either spouse during the marriage are community property, owned equally by both. Without a prenup specifying otherwise, that income and anything purchased with it would be subject to 50/50 division in a divorce.
Can a New Mexico prenup protect my oil and gas royalties?
Yes. Royalties from leases you owned before marriage can be characterized as separate property in a prenup. You can also specify how royalties from leases acquired during marriage will be treated, which is particularly important in New Mexico's oil-producing regions.
Are New Mexico prenuptial agreements enforceable if only one party had a lawyer?
New Mexico's UPMAA does not require both parties to have attorneys, but courts consider whether each party had a fair opportunity to consult independent counsel. An agreement signed where one party had no legal advice carries more risk of challenge.
Can we waive community property rights entirely in a New Mexico prenup?
Yes, couples can agree to treat all or most property as separate throughout the marriage, effectively opting out of New Mexico's community property system. This must be done clearly in writing with full financial disclosure and voluntary consent.
