Understanding Self-Proving Wills Under New Mexico Law
A self-proving will is a will that includes a special affidavit or affirmation allowing it to be admitted to probate without requiring witnesses to testify in court. In New Mexico, this process is governed by Section 45-2-504 NMSA 1978, which falls within the state’s Uniform Probate Code. For executors, personal representatives, and family members handling a loved one’s estate, a self-proving will can save significant time and reduce stress during the probate process.

How a Self-Proving Will Works in New Mexico
Under New Mexico law, a self-proving will carries a built-in verification mechanism that simplifies probate proceedings. Normally, when a will is submitted to probate, the court may need testimony from the witnesses who signed it. This can become difficult if years have passed since the will was executed, or if witnesses have moved away, become incapacitated, or passed away. A self-proving will eliminates this obstacle by attaching sworn statements at the time of signing.
Section 45-2-504 NMSA 1978 provides two pathways to make a will self-proving. Under Subsection A, a will may be simultaneously executed and made self-proving through the testator’s acknowledgment and affidavits or affirmations under penalty of perjury by the witnesses, each made before an officer authorized to administer oaths. Under Subsection B, an already-executed will can be made self-proving at any time after its execution by following the same acknowledgment and affidavit process, with the certificate attached to the will.
💡 Pro Tip: Even if your will was signed years ago without a self-proving affidavit, you may still be able to add one. New Mexico law allows you to make an existing attested will self-proving at any time after execution, as long as you and your witnesses complete the required affidavits before an authorized officer.
The 2017 Amendment: What Changed for Albuquerque Estate Planning
The 2017 amendment to Section 45-2-504, effective January 1, 2018, modernized the statute by adding "affirmations under penalty of perjury" as an alternative to traditional sworn oaths and by rewriting the statutory form language. These changes gave testators and witnesses more flexibility in how they verify a will and updated the declarations required in the self-proving forms. The updated language now accommodates individuals who may prefer an affirmation for personal or religious reasons.
This statute has been part of New Mexico’s Uniform Probate Code since 1975, with revisions in 1993, 1995, and 2017. If you are reviewing an older version of the law or relying on documents prepared before 2018, ensure your estate plan reflects current statutory requirements.
What the Testator and Witnesses Must Declare
The statutory forms in Section 45-2-504 require specific declarations from both the testator and each witness. The testator must declare that the document is their will, that it was read by them (or read and explained to them) before signing, that it clearly expresses their wishes, and that they sign it willingly and not under undue influence. These declarations address core issues courts examine when determining whether a will is valid: testamentary intent, voluntariness, and the circumstances of execution.
Each witness provides a sworn affidavit or affirmation confirming they observed the testator sign the will. These statements are made before an officer authorized to administer oaths, such as a notary public, who then affixes an official seal to the certificate.
| Requirement | Testator | Witnesses |
|---|---|---|
| Must sign or acknowledge the will | Yes | Yes (attest) |
| Declares document is their will and expresses their wishes | Yes | No |
| Declares will was read before signing and signed willingly | Yes | No |
| Provides affidavit or affirmation under penalty of perjury | Yes (acknowledgment) | Yes |
| Appears before authorized officer | Yes | Yes |
💡 Pro Tip: When selecting New Mexico will witnesses, choose individuals who are likely to be available and competent for years to come. While a self-proving affidavit reduces the need for witness testimony, having reliable witnesses still strengthens the overall integrity of your estate plan.
Why Self-Proving Wills Matter During Probate
A self-proving will provides meaningful legal advantages when submitted to probate, particularly in contested proceedings. Under NM Section 45-3-406(B), if a will is self-proved in a contested formal testacy case, compliance with signature requirements for execution is conclusively presumed, and other requirements of execution are presumed subject to rebuttal, without witness testimony. However, these presumptions may not apply if there is proof of fraud or forgery affecting the acknowledgment or affidavit.
For executors and family members in Albuquerque, this can make a significant difference in both the cost and duration of probate. Without a self-proving affidavit, the court may require live testimony or other evidence to confirm the will was validly executed, which can delay estate distribution and create unnecessary complications.
💡 Pro Tip: A self-proving affidavit does not make a will immune to all challenges. Courts may still consider evidence of fraud or forgery affecting the acknowledgment or affidavit itself. The affidavit streamlines the process but does not replace the need for a properly drafted and executed will.
The Role of the Self-Proving Affidavit Signature
Under Section 45-2-504(C), a signature affixed to a self-proving affidavit attached to a will is considered a signature affixed to the will itself if necessary to prove the will’s due execution. This provision serves as a practical safeguard when questions arise about whether the will was properly signed, allowing the affidavit signature to serve double duty.
This rule is particularly relevant for individuals creating a self-proving affidavit in New Mexico for the first time. Ensuring that all signatures are properly placed on both the will and the affidavit helps prevent technical objections during probate.
Simultaneous Execution vs. Post-Execution: Two Paths to a Self-Proving Will
Simultaneous Execution Under Subsection A
The most common approach is to make the will self-proving at the same time it is signed. Under Section 45-2-504(A), the testator, witnesses, and notary all participate in a single ceremony where the testator acknowledges the will, the witnesses provide their affidavits or affirmations, and the authorized officer certifies everything under official seal. This streamlined process is the standard recommendation for most people creating a new estate plan in Albuquerque, NM.
Making an Existing Will Self-Proving Under Subsection B
If a will was already executed without a self-proving affidavit, Subsection B allows the testator to add one later. The testator must acknowledge the will, and the original witnesses must provide their affidavits or affirmations before an authorized officer. The resulting certificate is then attached to the will.
💡 Pro Tip: If you are planning to make an existing will self-proving after execution, all original witnesses generally need to participate. Coordinate with your witnesses in advance to ensure availability, and work with a probate attorney in Albuquerque to prepare the correct forms.

Frequently Asked Questions
1. Does a self-proving will avoid probate entirely in New Mexico?
No, a self-proving will does not eliminate the probate process. It simplifies probate by reducing the evidentiary requirements for proving the will’s validity. The will must still be submitted to the court, and the personal representative must fulfill their duties to inventory assets, pay creditors, and distribute the estate.
2. Can I make my will self-proving without a notary?
The statute requires that the acknowledgment and affidavits or affirmations be made before an officer authorized to administer oaths, which typically means a notary public. Without this certification under official seal, the will may not qualify as self-proving under Section 45-2-504 NMSA 1978.
3. What happens if my self-proving will is challenged?
Under NM Section 45-3-406(B), a self-proved will in a contested case benefits from a conclusive presumption that signature requirements were met, and other execution requirements are presumed subject to rebuttal, without requiring witness testimony. However, if there is evidence of fraud or forgery affecting the acknowledgment or affidavit, those presumptions may not apply.
4. How many witnesses do I need for a valid will in New Mexico?
New Mexico generally requires at least two witnesses for an attested will. The witnesses must also participate in the self-proving affidavit or affirmation process if you want the will to qualify as self-proving under Section 45-2-504.
5. Is a notarized will the same as a self-proving will?
Not necessarily. Simply having a notary witness your signature does not make a will self-proving. The will must include the specific statutory affidavit or affirmation language required by Section 45-2-504 NMSA 1978, signed by the testator and witnesses before the notary, with the officer’s certificate under official seal.
