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.
Informal vs. Formal Probate: When Each Applies
| Situation | Informal Probate | Formal Probate |
|---|---|---|
| Uncontested will or no will | ✓ Available | Available but not required |
| Agreed-upon Personal Representative | ✓ Available | Available but not required |
| Will is being contested | Not available | Required |
| Disputed appointment of Personal Representative | Not available | Required |
| Disputed community vs. separate property characterization | Not typically available | May be required |
| Minor or incapacitated heir needs court protection | Not typically available | May be required |
| Straightforward estate, cooperative heirs | ✓ Best choice | Unnecessary cost |
How to File for Informal Probate
Step 1: Gather Required Documents
- Original will (if any) — the court keeps the original
- Certified copy of the death certificate (order 8–10 copies)
- Names, addresses, and ages of all heirs and devisees
- Your government-issued photo ID
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.
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:
- Open an estate bank account and consolidate estate funds
- Publish the creditor notice in a newspaper of general circulation
- Collect and review creditor claims; pay valid claims after the 60-day period closes
- File the deceased's final New Mexico Form PIT-1 and estate Form FID-1 if applicable
- Transfer real estate using a Personal Representative's Deed (record with County Clerk)
- Transfer vehicle titles through the New Mexico MVD
- Distribute remaining assets to heirs per the will or intestacy
- File the Closing Statement (NMSA § 45-3-1003) to formally close the estate
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 Form PIT-1: The deceased's final personal income tax return for the year of death. Due April 15 of the following year.
- New Mexico Form FID-1: Fiduciary income tax return for the estate — required if the estate earns income (interest, dividends, rent) during administration. Filed annually until the estate is closed.
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.
