What to Know Before Signing

Most U.S. states have adopted the Uniform Premarital Agreement Act (UPAA), which sets a baseline: prenups must be in writing and signed voluntarily. A few states, like New York, follow their own case law instead. Waiting periods, notarization, and independent-counsel rules differ. Confirm current law with a licensed attorney in the state.

The points above are a general reference for New Mexico. Prenup rules differ by state and can change, and this is not legal advice. Confirm current law with a licensed attorney in New Mexico.

Does New Mexico follow the Uniform Premarital Agreement Act?

Most states have adopted the UPAA, but confirm whether New Mexico does and what its specific rules are with a local attorney.
