New Mexico Probate Guide

New Mexico probate process guide covering the county Probate Court vs District Court split, the personal representative, small estates, deadlines, and costs.

By Settled Editorial

The New Mexico probate process starts with one practical choice: which court handles the estate, and which path fits the property left behind. New Mexico has a two-court split. Each county has an elected, part-time Probate Court judge who handles informal, uncontested probate of a will and appointment of a personal representative. The District Court, one of New Mexico's judicial districts, handles formal, supervised, or contested administration. New Mexico follows the Uniform Probate Code in NMSA 1978, Chapter 45, and the person who settles the estate is called the personal representative, not an executor or administrator. (See NMSA 1978, Section 45-1-302 and the New Mexico Judiciary Probate Courts page.)

Use this New Mexico probate guide as a planning map, not as legal advice or a filing packet. Each county Probate Court and each District Court can use local checklists, filing rules, payment methods, and document-review steps. Start with the New Mexico county and probate court directory, then confirm the packet with the right court before you sign or submit anything.

This guide also flags when a source-backed checklist is not enough. Disputes, debt problems, unclear heirs, and real estate sales can call for legal advice before anyone is appointed or distributes property.

Where New Mexico Probate Starts

New Mexico probate starts in the county where the decedent lived at death. The choice of court turns on whether the matter is contested.

The county Probate Court has original jurisdiction over informal proceedings. An elected probate judge can informally probate a will and appoint a personal representative when no one disputes the will or the appointment. The filing fee is a flat $30 per probate case under NMSA 1978, Section 34-7-14. Informal administration runs without ongoing court supervision.

The District Court has exclusive original jurisdiction over formal proceedings. That includes contested matters, supervised administration, will construction, determinations of heirs, and formal closing of estates. The civil docket fee runs about $132. The probate court and the district court share original jurisdiction over informal proceedings, so a personal representative can move a matter to District Court when a dispute appears. (Source: NMSA 1978, Section 45-1-302.)

One naming point trips people up. New Mexico does not use a "Surrogate's Court," and the fiduciary is not called an executor or administrator in the statute. New Mexico uses personal representative for the person appointed, whether or not there is a will. The court issues Letters Testamentary when a will controls, or Letters of Administration when there is no will.

The Main Estate Paths

A New Mexico probate guide should separate full administration from the smaller paths. The names sound alike, but the filing authority and the follow-up duties differ.

Full Administration

Full administration is the standard estate path. It starts when the court appoints a personal representative, informally before the county Probate Court or the District Court, or formally in District Court. Informal probate may not occur until at least 120 hours, meaning five days, have passed since death. (Source: NMSA 1978, Section 45-3-302.)

Once appointed, the personal representative gathers records, prepares an inventory, gives notice to creditors when needed, pays valid debts and taxes, and distributes the estate. Informal administration is unsupervised. Formal or supervised administration is overseen by the District Court. Full administration fits estates with solely owned accounts, unresolved debts, business interests, a disputed will, unclear heirs, or property that needs estate action to pay debts. When there is no will, the estate passes by intestate succession, which the New Mexico intestate succession guide covers in full.

Collection of Personal Property by Affidavit

New Mexico's small-estate path lets a successor collect personal property by affidavit when the value of the entire estate, wherever located, less liens and encumbrances, does not exceed $50,000, at least 30 days have passed since death, and no personal representative has been appointed or applied for. The successor presents the affidavit directly to the bank, transfer agent, or other holder. There is no court case to open. (Source: NMSA 1978, Section 45-3-1201.)

That $50,000 figure is a flat statutory amount, raised from $30,000 for deaths on or after January 1, 2012. The limit is not inflation-indexed, so it changes only by legislative amendment. Use the limit that applied on the decedent's date of death, and confirm the current number before you rely on it. The New Mexico small estate affidavit guide walks through this path step by step.

One limit matters here. The affidavit cannot be used to perfect title to real estate. If a house is involved, this path does not move the deed.

Closing a Small Estate Without Creditor Notice

New Mexico has no fixed-dollar "summary administration." Instead, a personal representative may immediately distribute and close a small estate when the inventory shows the entire estate, less liens and encumbrances, does not exceed the family allowance, the personal property allowance, costs of administration, last-illness medical and hospital expenses, and reasonable funeral expenses. Availability depends on the facts, so confirm it with the court before relying on it. (Source: NMSA 1978, Chapter 45, Section 45-3-1203.)

Community Property Shapes Who Inherits

New Mexico is a community property state, and that changes the intestate share for a surviving spouse. The rule is not the same as a separate-property state, so re-derive it from the statute rather than from a template.

When the decedent leaves no surviving issue, the surviving spouse takes all of the decedent's separate property. When the decedent leaves surviving issue, the spouse takes one-fourth of the separate property and the descendants take the other three-fourths by representation. For community property, the decedent's one-half interest passes to the surviving spouse in both cases, and the surviving spouse already owns the other half. So a surviving spouse usually ends up with all of the community property when the decedent dies without a will. (Source: NMSA 1978, Section 45-2-102.)

An heir must also survive the decedent by 120 hours to inherit, shown by clear and convincing evidence. The New Mexico intestate succession guide maps the full order of heirs, including parents, siblings, and grandparents, when there is no spouse or no descendants.

Real Estate and the Homestead Affidavit

This guide treats real estate separately, because New Mexico handles a community-property homestead differently from ordinary probate property. A surviving spouse can transfer title to a community-property homestead by recording an affidavit with the county clerk six months after death, where the assessed value does not exceed the statutory cap, without opening probate. (Source: NMSA 1978, Chapter 45, Section 45-3-1205.)

That shortcut does not cover every inherited house. Deed language, survivorship wording, will terms, debts, title-insurance rules, and sale plans can all change the next step. If a house is involved, check the deed record, the county assessor record, the mortgage status, and the creditor picture before anyone distributes or lists the property.

Documents to Gather Before Filing

This New Mexico probate guide starts with documents because the court, banks, creditors, and heirs ask many of the same questions. A short document stack makes the first conversation more useful.

Bring or locate:

  • Certified death certificates, ordered from the New Mexico Department of Health, Bureau of Vital Records and Health Statistics
  • The original will and any codicils, if found
  • Names, ages, and addresses for heirs and any named personal representative
  • A list of bank accounts, vehicles, personal property, business interests, and real property
  • Deeds, county assessor parcel records, and mortgage details for real estate
  • Vehicle title and registration details
  • Recent bills, creditor letters, funeral invoices, and tax notices
  • Beneficiary designations, payable-on-death records, transfer-on-death records, survivorship title records, and trust documents

The New Mexico death certificate guide can help plan certified-copy needs. The New Mexico vehicle transfer guide can help separate Motor Vehicle Division title work from court authority.

Timeline Signals to Track

Every estate is different, but this New Mexico probate guide uses a few timing signals as planning anchors. Confirm each one with the court for the specific estate.

TaskTiming signal
Choose the courtFile in the county where the decedent lived at death; county Probate Court for informal, District Court for formal or contested matters (NMSA 45-1-302)
Informal probate waitWait at least 120 hours, meaning five days, after death before informal probate (NMSA 45-3-302)
Small estate affidavitWait at least 30 days after death, with the estate at $50,000 or less, less liens and encumbrances (NMSA 45-3-1201)
Inventory and appraisementPrepare within three months after appointment and send it to interested persons who request it (NMSA 45-3-706)
Creditor claim barPublished notice once a week for three successive weeks starts a four-month claim bar from first publication (NMSA 45-3-801)
Ultimate creditor barAll claims arising before death are barred one year after the date of death, with or without notice (NMSA 45-3-803)

Notice to creditors is optional in New Mexico, not required. A personal representative may publish notice to start the four-month bar, and a creditor given actual written notice has the later of that four-month period or 60 days after mailing. The New Mexico probate timeline walks through these dates in more detail.

Costs, Taxes, and Compensation

New Mexico estate costs come in separate buckets, and other sources often blur them. Keep them apart.

First, the filing fee. The county Probate Court charges a flat $30 to open an informal, uncontested case under NMSA 1978, Section 34-7-14. The District Court charges about $132 in civil docket fees for a formal or contested case.

Second, the taxes. New Mexico imposes no probate tax, no state estate tax, and no inheritance tax. There is no value-based tax assessed on the estate when probate opens. Final individual income tax and federal estate tax for very large estates can still apply, and estate or trust income is subject to New Mexico fiduciary income tax.

Third, personal representative compensation. A personal representative is entitled to reasonable compensation under NMSA 1978, Section 45-3-719. New Mexico sets no fixed statutory percentage. The court reviews reasonableness based on the assets, the difficulty of the work, the time required, and the results. Do not import a percentage schedule from another state.

The New Mexico probate costs guide breaks down filing fees, copy fees, and compensation. Before filing, confirm with the court:

  • The correct county and the case type, informal or formal
  • Whether the original will must be presented
  • Whether a bond is required or waived
  • Which heirs and beneficiaries must receive notice
  • How filing fees and any publication costs must be paid

When to Get Legal Help

Some estates are simple enough to plan with official forms and court instructions. Others need legal advice before anyone is appointed, sells property, pays a creditor, or distributes money.

Consider talking with a New Mexico probate attorney when:

  • Heirs disagree about the will, the assets, or who should serve
  • The estate may not have enough money to pay its debts
  • Real estate must be sold to pay debts
  • The decedent owned property in more than one state
  • A business interest, lawsuit, tax issue, or Medicaid estate recovery issue is present
  • A creditor, beneficiary, or family member threatens a claim
  • The asset list or heir picture is unclear for a small-estate affidavit

This New Mexico probate guide can help organize the source-backed task list and the right court. A lawyer can advise on rights, strategy, disputes, and signing decisions.

Practical Filing Sequence

Use this sequence as a planning checklist:

  1. Locate the original will, certified death certificates, account records, title records, deeds, and creditor notices.
  2. Confirm the county where the decedent lived at death.
  3. Decide whether the estate appears to need full administration, the $50,000 collection-by-affidavit path, the community-property homestead affidavit, or no administration at all.
  4. Pick the right court. Use the county Probate Court for informal, uncontested matters, and the District Court for formal or contested matters.
  5. After appointment, track the three-month inventory, any four-month creditor bar, and the one-year ultimate claim bar.
  6. Keep receipts, filed copies, account statements, asset records, and distribution records together.
  7. Use the New Mexico probate checklist and your court page to hold the local packet, deadlines, and source notes in one place.

This New Mexico probate guide connects to deeper task pages as the rollout continues. Confirm every fact here with the right county Probate Court or District Court before you act, because this is a planning map, not legal advice.
