New Mexico Probate at a Glance

Here are the key facts about the New Mexico probate process:

Court that handles probate	County Probate Court (informal/uncontested matters) and District Court (formal/contested matters); New Mexico has 33 county probate courts and 13 judicial districts, both authorized under NMSA Chapter 45 (Uniform Probate Code)
Probate types available	Informal probate (uncontested, no hearing, filed in county probate court); Formal probate (contested or complex, hearing required, filed in district court); Supervised administration (court oversees every distribution, rare); Small estate affidavit (estates 50000 or less in gross probate assets, no court filing needed, available 30 days after death under NMSA 45-3-1201)
Typical timeline	6 to 12 months for informal probate; 12 to 18 months for formal probate; the 4-month creditor claim period (NMSA 45-3-801) sets the floor — notice must be published once per week for 3 successive weeks, then creditors have 4 months from first publication to file claims
Fastest option	Small estate affidavit for estates valued at 50000 or less — available 30 days after death with no court filing required; for estates above the threshold, informal probate through county probate court is fastest at roughly 6 months
Fee structure	REASONABLE-FEE state; New Mexico does not set attorney fees by statute — attorneys typically charge hourly or flat fees; personal representative compensation is set at a reasonable amount determined by the court under NMSA 45-3-719; total probate costs (attorney fees, publication, appraisals, filing) typically run 3 to 8 percent of the estate value
Typical total cost	3 to 8 percent of estate value for full probate including attorney fees, court costs, publication, and appraisals; simple informal estates may cost as little as a few hundred dollars if handled without an attorney; filing fees alone are among the lowest in the country
Court filing fee	30 for informal probate in county probate court; 132 for formal probate in district court
Executor compensation	Reasonable compensation as determined by the court under NMSA 45-3-719; New Mexico does NOT set a statutory percentage schedule — the court considers estate size, time and effort, complexity, and the representative’s skill; in practice personal representatives typically receive 2 to 4 percent of estate value but this is not guaranteed by statute; if the will specifies compensation, the PR may renounce the will’s provision before qualifying and claim reasonable compensation instead

⚠ In New Mexico, you generally have 3 years after death for informal probate (NMSA 45-3-108); a personal representative cannot be appointed until at least 120 hours (5 days) after the decedent’s death; after 3 years, formal probate may still be possible in limited circumstances such as establishing title to property to open probate after a death. Do not wait until the last minute — gather the will and death certificate early.

How to Avoid Probate in New Mexico

Revocable living trust; Transfer-on-death (TOD) beneficiary deed for real estate (recorded with county clerk before death, revocable during life); Payable-on-death (POD) designations on bank accounts; TOD registration for securities and brokerage accounts; Joint tenancy with right of survivorship; Life insurance and retirement accounts with named beneficiaries; Community property (New Mexico is a community property state — surviving spouse’s one-half passes automatically);

Small estate affidavit for estates 50000 or less (NMSA 45-3-1201)

Out-of-state property (ancillary probate): Yes — if a non-resident decedent owned real property or mineral rights in New Mexico, ancillary probate must be opened in New Mexico under NMSA Chapter 45, Article 4 (sections 45-4-101 through 45-4-207); two pathways exist: (1) full local administration with a NM-appointed personal representative,

or (2) simplified filing where the out-of-state PR submits a certified copy of their home-state appointment and an affidavit to act in NM without a new appointment (NMSA 45-4-201); an out-of-state executor appointment does NOT automatically confer authority over New Mexico assets

Other New Mexico probate rules: New Mexico is a community property state (1 of 9) — only the decedent’s one-half of marital property goes through probate; New Mexico has no state estate tax and no state inheritance tax — only federal estate tax applies; New Mexico adopted the Uniform Probate Code in 1975 as one of the original adopting states, emphasizing minimal court involvement for uncontested estates;

the 30 dollar informal probate filing fee is among the lowest in the nation; probate forms are standardized statewide under NMRA Form 4B series and available free from NM Courts; creditor notice requires publication once per week for 3 successive weeks followed by a 4-month claim window (NMSA 45-3-801)
