Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
San Miguel County Probate Court 500 West National Avenue, Suite 302, Las Vegas, NM 87701 (505) 425-9331 San Miguel County is in northeastern New Mexico, seated in Las Vegas (New Mexico).
Step 1: figure out which path applies
New Mexico adopted the Uniform Probate Code. New Mexico has a dual court system: the county PROBATE COURT handles informal, uncontested probate matters with minimal court involvement, and has concurrent jurisdiction with the DISTRICT COURT over informal proceedings. The District Court alone handles formal probate – contested cases, determinations of heirship, and trust matters.
Small Estate Affidavit / Affidavit of Successor in Interest (N.M. Stat. § 45-3-1201) – available when the value of the entire estate (after liens and encumbrances) does not exceed $50,000 and does NOT include any real property. At least 30 days must have passed since death. This skips probate court entirely – the affidavit is presented directly to banks, the DMV, or other institutions holding the property.
Homestead Transfer Affidavit for Surviving Spouse (N.M. Stat. § 45-3-1205) – available 6 months after death, when the surviving spouse and decedent owned a homestead as community property valued at $500,000 or less (for property tax purposes). The affidavit is recorded with the county clerk and can avoid formal probate for the residence, but only if funeral expenses, expenses of last illness, and all unsecured debts have already been paid.
Informal Probate – the most common path for uncontested estates, filed with either the Probate Court or the District Court in the county where the decedent was domiciled. No hearing required.
Formal Probate – required for contested cases, disputes over heirship, or trust matters. Only the District Court can hear these.
Step 2: filing for informal or formal probate
File a petition with the Probate Court or District Court in the county where the decedent was domiciled. A probate may be started up to 3 years after death.
The court appoints the personal representative and issues Letters Testamentary or Letters of Administration.
The personal representative notifies creditors; New Mexico’s creditor claim period is 2 months from notice to creditors – one of the shortest in the country.
The personal representative inventories the estate’s assets, pays debts and expenses, and distributes the remaining assets according to the will or New Mexico’s intestacy statute.
The estate is closed, typically within 6 to 12 months for straightforward, uncontested cases.
What it costs
The filing fee for probate in Probate Court is generally around $30 – notably lower than in most states. District Court filing fees run higher, commonly $100–$232 depending on the county and complexity.
New Mexico does not set a fixed statutory percentage for personal representative compensation; courts typically look to a reasonable guideline of about 2–4% of the estate’s value.
New Mexico has no state estate tax and no state inheritance tax. Only the federal estate tax could apply, and only to very large estates.
