New Mexico is a community property state — most assets acquired during marriage are jointly owned — and follows the Uniform Probate Code, making it one of the more accessible probate systems in the Southwest. The state has no estate tax, a $50,000 small estate threshold, and a single combined advance directive form that covers both healthcare agent and treatment preferences. This guide covers the six areas where New Mexico law most affects what you need to do after a death.
New Mexico's community property rules mean the surviving spouse often already owns half of all marital assets — only the deceased's half typically goes through the estate.
- Estates worth $50,000 or less with no real property can use a small estate affidavit instead of probate.
- New Mexico follows the Uniform Probate Code, making informal probate available for most uncontested estates.
- There is no state estate tax. Only the federal estate tax may apply, and only for large estates.
Probate
Probate & Small Estate Rules in New Mexico
New Mexico probate is filed in the District Court of the county where the deceased was domiciled. New Mexico adopted the Uniform Probate Code (UPC), which makes the system more straightforward than in many states — most uncontested estates qualify for informal probate without extensive court supervision.
New Mexico's small estate affidavit allows heirs to collect the deceased's property without opening probate when the entire estate is worth $50,000 or less and includes no real property. The affidavit may be used 30 days after the date of death under NMSA § 45-3-1201. Real property is excluded from the small estate affidavit path — it must pass through probate, a living trust, a transfer-on-death deed, or joint ownership with survivorship rights.
When full probate is required, New Mexico's UPC framework allows the personal representative to administer the estate with minimal court involvement under informal probate. Once notice is published, creditors must present claims within 4 months after the first publication of the notice to creditors, or within 60 days after a written notice is mailed or delivered to them, whichever is later (NMSA §§ 45-3-801 to 45-3-803). Executor compensation is set at a reasonable amount rather than a fixed statutory schedule. Informal probate typically concludes in 6–12 months.

Wills
Will Signing Requirements in New Mexico
A valid New Mexico will requires the signature of the testator plus two witnesses, each of whom watches the testator sign and then signs in the presence of the testator and of each other (NMSA § 45-2-502). Notarization is not required for a standard witnessed will, though a self-proving affidavit — signed before a notary — is available and is strongly recommended. A self-proved will is accepted by the court without requiring the witnesses to testify, which can save time and cost during probate.
New Mexico does not recognize holographic wills — a handwritten will without two witnesses is not valid if it was made in New Mexico. The one exception is a will that was validly made in another state or country that allows holographic wills (NMSA § 45-2-506). If you find a handwritten document that appears to be a will, do not discard it — have a New Mexico probate attorney review it.
If a person dies without a valid will, New Mexico's intestate succession law (NMSA § 45-2-102) determines who inherits. For community property, the deceased's half generally passes to the surviving spouse. For the deceased's separate property, the surviving spouse takes everything if the deceased left no children or other descendants; if there are descendants, the spouse takes one-quarter and the descendants share the other three-quarters.
Advance Directive
New Mexico Advance Health Care Directive
New Mexico uses a single combined Advance Health Care Directive that covers both the appointment of a healthcare agent and the declaration of treatment preferences (NMSA § 24-7A). This means one document handles what some states split into separate forms — a healthcare proxy and a living will.
To be valid, a New Mexico advance directive must be signed by the principal (NMSA § 24-7A-2). Witnesses are recommended on the state's sample form but are not required by the statute. The agent's authority is active when the principal loses capacity to make healthcare decisions and ends at the principal's death — it does not extend into estate matters.
New Mexico also uses a POLST form (Physician Orders for Life-Sustaining Treatment) — a physician-signed medical order that governs immediate, specific medical decisions such as resuscitation and artificial nutrition. The POLST and the Advance Directive can coexist: the POLST governs real-time clinical decisions, while the Advance Directive names an agent and covers broader treatment preferences.
Community Property
How Community Property Works at Death in New Mexico
New Mexico is one of nine community property states. Under New Mexico law, all property acquired by either spouse during the marriage is jointly owned — each spouse holds an undivided one-half interest. Property owned before marriage, or received as a gift or inheritance during the marriage, is separate property belonging to that spouse alone.
At death, the deceased spouse can only dispose of their half of community property through a will or trust. The surviving spouse's half is already theirs — it does not pass through the estate at all. This has major practical implications:
- If the deceased had no will, their half of community property generally passes to the surviving spouse under New Mexico's intestate succession law.
- If there is a will that leaves the deceased's half to someone other than the surviving spouse, the surviving spouse retains their undivided half regardless.
- New Mexico allows community property with right of survivorship — if title is held this way, the surviving spouse takes the full asset at death without any probate proceeding.
Community property also carries a significant federal tax advantage: both the deceased's half and the surviving spouse's half receive a full stepped-up cost basis at death. This reduces capital gains tax if the surviving spouse later sells the asset — an advantage not available in common-law states, where only the deceased's share is stepped up.
Vehicle Transfer
Transferring a Vehicle After Death in New Mexico
New Mexico allows vehicles belonging to qualifying estates to be transferred without formal probate using the small estate affidavit path at the New Mexico Motor Vehicle Division (MVD). The affidavit can be used when the entire estate is worth $50,000 or less with no real property and 30 days have passed since the date of death.
For larger estates that require Letters Testamentary, the personal representative presents those letters to the MVD along with the title and a certified copy of the death certificate to transfer ownership. The vehicle title is then reissued in the name of the estate or a specific heir as directed.
Vehicles held as community property or in joint tenancy with survivorship rights transfer directly to the surviving co-owner upon presentation of a certified death certificate — no probate, no MVD affidavit required. Vehicles held in a living trust transfer to the successor trustee without court involvement, one of the practical advantages of a revocable trust in New Mexico.
Medicaid Recovery
New Mexico Medicaid Estate Recovery
New Mexico Medicaid, administered by the Human Services Department / Medical Assistance Division (HSD/MAD), has the right to seek reimbursement from a deceased beneficiary's estate for long-term care costs paid after age 55. This includes nursing facility care, home and community-based waiver services, and related hospital and prescription costs paid by Medicaid.
Recovery is limited to the probate estate — assets that must pass through court. Assets that transfer outside probate (joint tenancy, community property with right of survivorship, beneficiary designations, living trusts) are generally not subject to recovery. If you are settling an estate where the deceased received New Mexico Medicaid for long-term care, you should:
- Notify HSD/MAD before distributing any assets from the estate.
- Determine which assets are in the probate estate versus which transfer outside of probate — only the former are at risk of a recovery claim.
- Confirm whether any exemption applies: recovery is deferred while a surviving spouse is living, a minor child is living, or a blind or disabled child of any age is living.
Distributing estate assets without first addressing a potential Medicaid recovery claim can expose heirs to personal liability. When in doubt, contact HSD/MAD directly to request a recovery claim determination before making any distributions.

Frequently Asked Questions
What is the small estate threshold in New Mexico?
New Mexico's small estate affidavit can be used when the entire estate is worth $50,000 or less and includes no real property. The affidavit may be used 30 days after death under NMSA § 45-3-1201. Real property is not covered and must go through probate or another transfer mechanism such as a TOD deed or living trust.
Does New Mexico have a state estate tax?
No. New Mexico does not impose a state estate tax or inheritance tax. Only the federal estate tax may apply, and it affects only estates above the federal exemption threshold (currently $15 million per person as of 2026).
Is New Mexico a community property state?
Yes. New Mexico is one of nine community property states. All property acquired by either spouse during the marriage is jointly owned — each spouse holds an undivided one-half interest. The surviving spouse already owns their half, so only the deceased spouse's half typically passes through the estate.
What is the creditor claim period in New Mexico probate?
In New Mexico, creditors must present claims within 4 months after the first publication of the notice to creditors, or within 60 days after a written notice is mailed or delivered to them, whichever is later (NMSA §§ 45-3-801 to 45-3-803).
Does New Mexico recognize holographic wills?
No. New Mexico does not recognize holographic (handwritten, unwitnessed) wills made in New Mexico; a valid will needs two witnesses who sign in the presence of the testator and each other (NMSA § 45-2-502). A handwritten will validly made in another state may still be honored (NMSA § 45-2-506).
How does Medicaid estate recovery work in New Mexico?
New Mexico Medicaid (HSD/MAD) may recover long-term care costs from the probate estates of beneficiaries age 55 and older. Recovery is deferred while a surviving spouse, minor child, or blind or disabled child is living. Notify HSD before distributing any estate assets.
