Is an Online Will Legal in New Mexico?
An online service can prepare a valid New Mexico will, but execution is strictly on paper and in person under § 45-2-502: the testator signs (or directs a signing in the testator's conscious presence), and two witnesses who actually watched that signing then sign in the presence of the testator and of each other. New Mexico recognizes neither electronic wills nor holographic wills.

What this means for you
New Mexico's witnessing rule is stricter than in most states: both witnesses must see the testator sign, and everyone signs together in one sitting. There is also no harmless-error rescue for a botched signing, because § 45-2-503 was left reserved, so a ceremony that misses a formality simply fails. Adding the § 45-2-504 self-proving affidavit before a notary or other oath officer at the signing lets the will into probate without witness testimony.
What New Mexico Law Requires
The governing law is NMSA 1978, ch. 45 (Uniform Probate Code), art. 2, pt. 5 (Wills), §§ 45-2-501 to 45-2-517. Each rule below links to the official source it was read from.
| Requirement | The New Mexico rule | Statute |
|---|---|---|
| Who can make a will | Age 18 or older, sound mind; emancipated minors qualify. | NMSA 1978, § 45-2-501 |
| Written document | Required. | NMSA 1978, § 45-2-502(A) |
| Signature | The testator signs. The will may be signed in the testator's name by some other individual in the testator's conscious presence and by the testator's direction. | NMSA 1978, § 45-2-502(B) |
| Witnesses | 2. The will must be signed by at least two individuals, each of whom signed in the presence of the testator and of each other after each witnessed the signing of the will. New Mexico departs from the Uniform Probate Code here: each witness must actually observe the testator's (or the proxy's) signing, not merely a later acknowledgment, and the witnesses must sign in the presence of the testator and of each other. | NMSA 1978, § 45-2-502(C) |
| Notarization | Not required for validity. A self-proving affidavit is optional and speeds probate. | NMSA 1978, § 45-2-504 |
Signing Day in New Mexico
The will must be signed by at least two individuals, each of whom signed in the presence of the testator and of each other after each witnessed the signing of the will. New Mexico departs from the Uniform Probate Code here: each witness must actually observe the testator's (or the proxy's) signing, not merely a later acknowledgment, and the witnesses must sign in the presence of the testator and of each other.
This is one of the strictest witnessing rules in the country; the whole signing happens with testator and both witnesses together.
The self-proving step worth adding
Self-proof runs on the testator's acknowledgment and the witnesses' affidavits or affirmations under penalty of perjury, evidenced by the officer's certificate under official seal in the statutory form; the New Mexico form recites that the testator signed in the presence of both witnesses and that the witnesses signed in the presence of the testator and of each other, matching § 45-2-502(C). Timing: at execution (simultaneously executed, attested and made self-proved) or at any time after execution.
Choose witnesses carefully
An individual generally competent to be a witness may act as a witness to a will, and the signing of a will by an interested witness does not invalidate the will or any provision of it. New Mexico has no purging statute; the interested witness keeps the gift.
Shortcuts New Mexico Does and Does Not Recognize
Handwritten (holographic) wills
NoNew Mexico does not recognize holographic wills. Section 45-2-502 makes two witnesses who watched the signing mandatory for every will executed in New Mexico, and § 45-2-503, where the UPC's harmless-error rescue would sit, is reserved with no text, so an unwitnessed handwritten will fails the execution formalities. A holographic will validly executed under the law of the place where it was executed or of the testator's domicile can still be given effect through § 45-2-506. (NMSA 1978, § 45-2-502)
Oral wills
NoSection 45-2-502(A) requires every will executed in New Mexico to be in writing, and no provision of the New Mexico Uniform Probate Code authorizes a nuncupative (oral) will, so spoken words cannot operate as a New Mexico will. (NMSA 1978, § 45-2-502(A))
Electronic wills
NoNew Mexico has not enacted an electronic-wills act. NMSA 1978 Chapter 45 contains no electronic-will provision (a full-text search of the official compilation returns none), and § 45-2-502 requires a signed writing witnessed by two individuals who sign in the presence of the testator and of each other. A will prepared online must be printed and signed on paper, in person. (NMSA 1978, § 45-2-502)
A Will Signed in Another State
A written will is valid if executed in compliance with § 45-2-502 or if its execution complies with the law at the time of execution of the place where the will is executed, or with the law of the place where, at the time of execution or at the time of death, the testator is domiciled, has a place of abode or is a national. (NMSA 1978, § 45-2-506)
