Is a self-written will legal in New Mexico?
Yes. New Mexico recognizes wills you write yourself, as long as they meet the state's signing requirements. The governing statute is N.M. Stat. §45-2-501 et seq.
Your will needs to be in writing, signed by you, and witnessed by 2 adults who are present at the same time. You don't need a notary for the will itself to be valid, but adding a notarized "self-proving" affidavit makes the probate process faster later (this tool generates that for you automatically).
You must be at least 18 years old and of sound mind. An emancipated minor may also make a will (N.M. Stat. §45-2-501). Choose witnesses who don't inherit under your will: some states void or reduce a gift to a witness, and the exact New Mexico rule is covered below. This tool walks you through the rules so you don't trip over them.
A will you write yourself has the same legal force as one drafted by an attorney, provided you follow the signing rules. Courts admit self-written wills to probate every day. An attorney's value is in advising on complex estates, not in drafting the document itself.
What it costs to make a will in New Mexico
A New Mexico estate-planning attorney typically charges $300 to $600 for a simple will, and $1,000 to $1,500 for a will-plus-revocable-trust package. Rates run higher in dense metros and lower in rural areas. Most attorneys bill at $250 to $400 per hour and need one or two meetings to draft a basic will.
You can also write a will entirely from scratch with a sheet of paper and a pen, with no software at all. New Mexico requires the same 2-witness signing process regardless of who drafts the document. The risk with a from-scratch will is technical: a missing self-proving affidavit, a witness who's also a beneficiary, or wording that creates ambiguity for the probate court. That's what this tool prevents.

When you might want an attorney instead
An online will works for most people. It's the right tool when your situation is straightforward: you want to leave your assets to family or friends, you don't have complex tax issues, and you're not anticipating a fight over your estate.
Consider hiring an attorney if any of these apply:
- Your estate is large enough to trigger federal estate tax (over $15 million in 2026) or New Mexico estate or inheritance tax.
- You own a business, complex investments, or assets in multiple states or countries.
- You're in a blended family, especially if you want to leave assets to a current spouse while protecting children from a prior relationship.
- You have a child or beneficiary with special needs and want a supplemental-needs trust that won't disqualify them from public benefits.
- You expect someone to contest the will, or you're disinheriting a close family member.
- You have substantial retirement accounts and want sophisticated beneficiary planning.
If none of these apply, an online will is genuinely fine. The legal validity of your will doesn't depend on who drafted it, only on whether New Mexico's signing rules were followed.
Self-proving affidavit in New Mexico
New Mexico recognizes self-proving affidavits. Will.com attaches one to your will: a short statement your witnesses sign in front of a notary, swearing to what they saw when you signed. See N.M. Stat. §45-2-504.
A self-proven will skips the requirement to track down witnesses years later for the probate court. It's optional, but adding the affidavit at signing time saves your executor work. Will.com generates the affidavit alongside the will.
Who can witness your will in New Mexico
NMSA §45-2-505: 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 follows the UPC rule and has no purge statute, so a gift to an attesting witness remains effective. Using witnesses who take nothing under the will is still the safer practice.
Family changes after you sign
A child born or adopted after the will. A child who arrives after you sign, and who isn't named or accounted for in the will, is covered by New Mexico law rather than by your wishes. The safest practice is to update your will when your family changes.
N.M. Stat. §45-2-302: a child born or adopted after the will is executed and not provided for in the will takes a share. If the testator had no child living when the will was executed, the omitted child receives a share equal in value to an intestate share, unless the will devised all or substantially all of the estate to the omitted child's other parent and that other parent survives the testator and is entitled to take under the will (§45-2-302(A)(1)). If the testator had one or more children living when the will was executed and devised property to one or more of them, the omitted child shares only in the devises made to those then-living children, taking the share the child would have received had the testator divided those devises equally among the then-living children and every omitted child, with the then-living children's devises abating ratably and the character of the testamentary plan preserved so far as possible (§45-2-302(A)(2)). None of this applies if it appears from the will that the omission was intentional, or if the testator provided for the child by a transfer outside the will intended in lieu of a testamentary provision (§45-2-302(B)). A living child omitted solely because the testator believed the child to be dead is treated as an omitted after-born child (§45-2-302(C)).
A spouse you married after signing. Updating the will after marriage avoids relying on whatever New Mexico law provides by default.
N.M. Stat. §45-2-301: a surviving spouse who married the testator after the will was executed is entitled to an intestate share, less any portion of the estate devised to a pre-existing child of the testator who is not a child of the surviving spouse (or to a descendant of such a child), unless the will was made in contemplation of the marriage, the will states it is effective notwithstanding any later marriage, or the testator provided for the spouse outside the will with intent that the transfer be in lieu of a testamentary provision.
