How to sign a will in New Mexico

  1. Print your will and read every word. Fill in any blanks in ink, but don't sign yet.
  2. Choose two adult witnesses who receive nothing under your will and aren't married to anyone who does.
  3. Sign and date your will in front of both witnesses, at the same time. Then each witness signs while you and the other witness watch.
  4. Make it self-proving. You and your witnesses sign a short self-proving affidavit in front of a notary, so the court won't need to find your witnesses later. (NMSA 1978 §45-2-504 (the form recites that witnesses signed in the presence of the testator and each other))
  5. Store the original safely and tell your executor where it is. New Mexico also lets you deposit your will with the probate court for safekeeping.

Who can make a will

Anyone 18 or older and of sound mind. An emancipated minor of sound mind may also make a will (NMSA 1978 §45-2-501).

Witness rules

In writing, signed by the testator (or by another in the testator's conscious presence at the testator's direction), and signed by at least 2 witnesses, each signing in the presence of the testator AND of each other after witnessing the testator's signing (NMSA §45-2-502).

If a witness inherits: No effect: signing by an interested witness does not invalidate the will or any provision (NMSA §45-2-505).

Handwritten wills

Not recognized: §45-2-502 has no holographic exception.

Self-proving affidavit

New Mexico lets you and your witnesses sign a self-proving affidavit, so the court can accept your will without contacting your witnesses. (NMSA 1978 §45-2-504 (the form recites that witnesses signed in the presence of the testator and each other))

Can I sign my will online in New Mexico?

No. No electronic-will statute or 2025-2026 bill found.

Print your will and sign it on paper with your witnesses in the same room.

Online notarization: RULONA lets a remotely located individual appear by communication technology. The Probate Code's in-presence witnessing rule (§45-2-502) suggests witnesses must be physically together, but neither law addresses a remote self-proving affidavit. (NMSA 1978, ch. 14, art. 14A (Revised Uniform Law on Notarial Acts, 2021 SB 12, eff. 2022-01-01))
