New Mexico Informal Probate: Opening an Estate Without a Court Hearing

New Mexico adopted the Uniform Probate Code, which means most estates qualify for informal probate — reviewed administratively by the probate registrar, not a judge. No court hearing, no scheduling delays. New Mexico is also a community property state, which affects how the estate inventory is prepared.

New Mexico's UPC Framework

New Mexico Statutes Annotated (NMSA) 1978 Article 45 adopts the Uniform Probate Code — the same framework used in Colorado, Utah, Wyoming, Montana, Idaho, and several other states. Under the UPC, most estates can be administered through informal probate without ever appearing before a judge. The probate registrar reviews the filing paperwork and issues the Order of appointment.

Once appointed, the Personal Representative handles administration independently — paying creditors, managing assets, filing taxes, and distributing to heirs — without returning to court for each action.

Community property note: New Mexico is a community property state. Only the decedent's separate property and the decedent's half of community property are part of the probate estate. The surviving spouse's half of community property passes to them automatically and is not part of the estate.

How to File for Informal Probate

Step 1: Gather Required Documents

Step 2: File the Application

File the Application for Informal Probate of Will and/or Appointment of Personal Representative with the District Court (or Probate Court, in counties that have one — Bernalillo County has a dedicated Probate Court) in the county where the decedent was domiciled at death. Forms are available from the New Mexico Courts Self-Help Center at nmcourts.gov/self-help/probate/. Filing fee is approximately $90–$135, depending on the county and court.

Step 3: Probate Registrar Review

The probate registrar reviews the application. No hearing is scheduled, no courtroom appearance required. If requirements are met, the registrar issues an Order Appointing Personal Representative. If the will is contested or the appointment is disputed, the matter is referred to a judge for formal probate.

Step 4: Receive Letters Testamentary

Upon the Order being issued, the court provides Letters Testamentary (if there is a will) or Letters of Administration (if there is no will). Request 6–10 certified copies — each institution requires its own certified copy.

30-day heir notice deadline: Within 30 days of appointment, mail notice to all heirs and devisees stating your name and address as Personal Representative, the decedent's name and date of death, and that the recipient may have an interest in the estate (NMSA § 45-3-705). Keep proof of mailing for the Closing Statement.

Independent Administration After Appointment

New Mexico's UPC framework gives the Personal Representative broad authority to administer the estate without returning to court. With Letters Testamentary, you can:

Creditor Notice Publication

After appointment, publish a Notice to Creditors once a week for two consecutive weeks in a newspaper of general circulation in the county. The 60-day claim period begins at first publication (NMSA § 45-3-801). Mail separate notice to all known creditors. Do not distribute assets to heirs until the creditor period closes and all claims are resolved.

New Mexico Income Tax — What Personal Representatives Must Know

New Mexico has a progressive income tax with rates from 1.7% to 5.9% (2024 rates). Two returns may be required:

New Mexico has no state estate or inheritance tax — no New Mexico estate tax return is required.

Closing the Estate

After all assets are distributed, all debts paid, and all tax returns filed, file the Closing Statement (NMSA § 45-3-1003) with the court. The Closing Statement cannot be filed until at least 6 months after your appointment. It formally closes the estate and discharges you as Personal Representative.

New Mexico Courts Self-Help Center: The New Mexico Courts website (nmcourts.gov/self-help/probate/) provides official probate forms, step-by-step guides, and county-specific contact information. Visit before filing to get the current forms and any county- or court-specific requirements. Note that Bernalillo County uses the Probate Court rather than the District Court for most informal probate matters.
