The rules in New Mexico
How many witnesses does a will need in New Mexico?
A will in New Mexico must be signed in front of two witnesses, who sign it too.
Can a will be self-proved in New Mexico?
Yes. New Mexico allows a self-proving affidavit, which lets a court accept the will without calling the witnesses to testify.

No. New Mexico does not recognize unwitnessed handwritten wills made under its own law.
Where do the New Mexico rules for wills come from?
They come from NMSA 45-2-502 Execution; witnessed wills and NMSA 45-2-504 Self-proved will. We last checked them in October 2026. Laws change, so check the current statute before you rely on it.
How New Mexico compares
27 jurisdictions recognize handwritten wills; New Mexico is not one of them, so a will made there should be witnessed.
What this means in practice
Sign the will in front of all the witnesses at the same time and have them sign right after you. Many people choose adult witnesses who receive nothing under the will, which avoids questions later.
Keep the signed original somewhere safe and tell your executor where it is. A copy is usually not enough to probate a will.
Changing a will later takes the same formalities: sign a codicil or a new will with witnesses, rather than writing changes on the original.
