What to Do When Someone Dies in New Mexico: A Step-by-Step Guide

The administrative tasks after a death in New Mexico follow a specific legal sequence, with hard deadlines that apply whether or not you've had time to grieve. Missing the 24-hour refrigeration requirement, filing the death certificate after the five-day window, or failing to get OMI clearance before a cremation can halt everything and force you to start over.

This guide walks through the required steps in order — what must happen in the first 24 hours, what must happen in the first five days, and what comes after.

First: Determine Who Is Legally in Charge

Before any disposition decisions are made, New Mexico law requires identifying who has the legal right to control the funeral and final disposition. If the deceased left written instructions designating a specific person, that person has legal authority. If not, the right passes through a statutory hierarchy (NMSA 1978, Section 24-12A-2):

1. A person explicitly designated in the deceased's written instructions
2. Surviving spouse
3. A majority of the surviving adult children
4. Surviving parents
5. A majority of the surviving siblings
6. The next degree of kinship under New Mexico intestate succession

The "majority" rule for children and siblings matters: if three adult children disagree two-to-one, the majority position controls. If there's an even split — two children, each refusing to consent to the other's choice — a court must intervene. Establishing who is in charge early prevents the funeral home from being unable to take direction from anyone.

Within 24 Hours of Death

If the death was unexpected or occurred at home without a physician present, call the Office of the Medical Investigator (OMI). Do not move or disturb the body until the OMI arrives, assumes custody, and releases the scene. The OMI will handle transport and the medical certification of death.

If the death occurred under medical supervision (hospice, hospital, nursing facility), the attending physician or nurse practitioner will initiate the death certificate process.

Refrigeration or embalming must happen within 24 hours. New Mexico law requires that remains be stored at or below 40°F (5°C) within 24 hours of death. If you are using a funeral home, this is handled automatically. If you are conducting a home funeral, you are responsible for maintaining the remains below this temperature until burial.

Contact a funeral home or begin home funeral arrangements. If using a funeral home, they'll take over logistics including collection of the remains, death certificate preparation, and coordination with the OMI if needed. If you're handling a home funeral, begin gathering the demographic information needed for the death certificate.

Within 48 Hours of Death

The medical certification of the cause of death must be completed. The attending physician, nurse practitioner, or the OMI must sign the medical portion of the death certificate within 48 hours. All New Mexico death certificates are processed through the Electronic Death Registration System (EDRS). If the certifying physician is unavailable, contact the healthcare facility to designate a backup signer.

Within 5 Days of Death

File the death certificate before any disposition. NMSA 1978, Section 24-14-20 requires the death certificate to be completed and registered within five days and always before burial or cremation. The funeral home handles this electronically if they're involved. If you're conducting a home funeral, the family member acting as informant must submit the demographic section through the EDRS system.

Order certified death certificate copies. Each certified copy costs $5 from the New Mexico Bureau of Vital Records. Order at least 8–10 copies immediately — you will need separate originals for banks, life insurance companies, the Social Security Administration, the motor vehicle division, the county probate court, and any pension administrators. Ordering too few copies and having to re-order extends every other process.

Obtain a burial-transit permit if needed. If a licensed funeral home is handling the disposition, no separate burial-transit permit is required. If a family member is personally managing a home burial or home funeral, a burial-transit permit must be obtained from the state registrar or local health department before disposition occurs.

Before Cremation Can Proceed

Two authorizations are required before any cremation in New Mexico:

Cremation authorization from the next of kin. The person with legal disposition authority must sign a Cremation Authorization form. The funeral home provides this document.

Cremation permit from the OMI. The funeral director submits the completed death certificate to the Office of the Medical Investigator, which reviews the case and issues a cremation permit. The standard OMI review fee is $230. This appears as a cash advance on your funeral home invoice. Cremation cannot begin until the OMI permit is in hand.

If the OMI assumes jurisdiction (sudden, unexplained, or violent death), the cremation permit will be delayed until the investigation concludes. There is no fixed timeline for OMI investigations — contact the OMI directly for case status rather than relying on the funeral home as an intermediary.

Days 5 to 30: Estate Inventory

Locate the will. A will may be held by an attorney, filed with the county clerk, or kept in a safe deposit box. If it was deposited with a New Mexico court prior to death, the court has it on file. Do not delay locating the will — it controls who receives property and who is authorized to act as personal representative.

Identify non-probate assets. Many assets transfer automatically without going through probate: bank accounts with Payable on Death (POD) designations, real estate held jointly with rights of survivorship, property with a recorded Transfer on Death Deed, retirement accounts and life insurance with named beneficiaries. For these assets, present a certified death certificate to the institution, and they will complete the transfer without court involvement.

Notify Social Security. The SSA must be notified promptly. If the deceased received monthly benefits, any payments received for the month of death or after must be returned. A surviving spouse 60 or older (or 50 and disabled) may be eligible for survivor benefits. The one-time death benefit of $255 is available to eligible surviving spouses or dependent children.

After 30 Days: Probate or Small Estate Affidavit

Small estate affidavit (if estate qualifies). If the total estate value (excluding real property) is under $50,000 and no probate case is pending, the successor can bypass probate entirely by signing an Affidavit of Successor in Interest in front of a notary. This document allows the successor to transfer bank funds and vehicle titles directly without court involvement. The 30-day waiting period from the date of death must have passed.

Open probate if required. If the estate includes real property that doesn't pass by other means, or if the estate exceeds the small estate threshold, the personal representative must file a petition with the county probate court where the decedent lived. The filing fee is $30. The court will issue Letters Testamentary (with a will) or Letters of Administration (without a will), which authorize the personal representative to act on the estate's behalf.

After 6 Months: Spousal Homestead Affidavit

If a surviving spouse is inheriting the primary residence and the property's assessed value is under $500,000, probate can be bypassed by filing an Affidavit of Surviving Spouse with the county clerk. This affidavit can be filed starting six months after the date of death. The recording fee is approximately $25.

Ongoing: Watch for Medicaid Estate Recovery

If the deceased received Long-Term Care Medicaid services at age 55 or older, the New Mexico Health Care Authority may file a recovery claim against the estate. Statutory deferrals apply if the estate includes a surviving spouse, a child under 21, or a blind or disabled child. Hardship waivers are available for heirs who lived in the home continuously for 12 months before the recipient's death and have no other residential property.

Monitor mail carefully in the months after death for correspondence from the HCA or its contractor, Health Management Systems (HMS). Response deadlines for waiver applications are firm.
