New Mexico Probate Types: Small Estate Affidavit, Informal Probate, and Formal Administration
New Mexico runs a two-court split. The county Probate Court handles informal, uncontested probate for a flat $30, while the District Court handles formal, supervised, or contested administration for about $132. The path turns on whether the estate is small, uncontested, or contested, and on whether real estate is involved. The fiduciary is the personal representative.

How to Compare New Mexico Probate Types
New Mexico follows the Uniform Probate Code (NMSA 1978, Chapter 45) and uses a two-court structure. Each county has an elected, part-time Probate Court judge with original jurisdiction over informal, uncontested probate and appointment of a personal representative. The District Court, in one of 13 judicial districts, has exclusive jurisdiction over formal, supervised, and contested matters. New Mexico calls the fiduciary the personal representative, not an executor or administrator, and the court issues Letters Testamentary (with a will) or Letters of Administration (no will).
The path usually turns on the size of the estate and whether anyone disputes the will or the appointment. The smallest personal-property estates can use the collection of personal property by affidavit (up to $50,000); uncontested estates use informal probate; and contested, supervised, or formal-closing estates go to District Court. New Mexico is a community property state, so a surviving spouse already owns half of the community property, which can shrink the estate that must pass through probate. A non-resident who owned New Mexico real property may need an ancillary proceeding.

| Category | Simplified Path | Formal Path | Winner |
|---|---|---|---|
| Estate size | The collection-by-affidavit path uses a $50,000 cap on the entire estate, less liens and encumbrances | Informal and formal administration have no dollar cap | Simplified Path |
| Court involvement | The affidavit needs no court filing; informal probate is an unsupervised $30 Probate Court path | Formal or supervised administration is full District Court oversight with Letters issued to a personal representative | Simplified Path |
| Real property | The affidavit cannot perfect title to real estate; informal probate can transfer it | Formal administration can address real property through estate authority and supervised sale | Tie |
| Creditor claims | Notice to creditors is optional; publishing once a week for three weeks starts a four-month claim bar | Formal administration adds District Court review of claims, accountings, and distribution | Simplified Path |
| Disputes | The affidavit and informal probate are poor fits for contested estates or significant debts | Formal or supervised administration is built for contested wills, unclear heirs, and supervised distribution | Formal Path |

* New Mexico probate is split between two courts. The county Probate Court charges a flat $30 docket fee under NMSA 1978, Section 34-7-14 to open informal, uncontested probate. The District Court charges about $132 in civil docket fees under NMSA 1978, Section 34-6-40 for a formal or contested case. Neither fee scales with estate value. The small-estate affidavit has no court filing fee because it is presented to the asset holder. Confirm the current schedule with the court before filing.
