New Mexico Informal vs Formal Probate

New Mexico splits probate across two different courts entirely — a county Probate Court for the easy cases, and the District Court for everything that isn't.

NMSA § 45-1-302

By the FigureMyTax Editorial Team · How we calculate

Why New Mexico uses two courts at all

A genuinely distinctive structure: New Mexico's county Probate Court is run by an elected probate judge who isn't required to be a lawyer, and it handles the large majority of uncontested, informal estates. The moment a matter needs formal, supervised administration — because of a contested will, a disputed appointment, or another genuine dispute — jurisdiction shifts to the Probate Division of the District Court, which under § 45-1-302 holds exclusive authority over those formal proceedings.

Executor vs administrator is a separate question

Independently of which court and track apply, New Mexico's Uniform Probate Code generally refers to both an executor (named in a will) and an administrator (appointed when there's no will) as the personal representative — either can proceed through informal or formal probate as the facts of the estate require.

Informal vs formal — frequently asked questions

What's the difference between informal and formal probate in New Mexico?

Informal probate is handled by the county Probate Court, often before an elected, non-lawyer probate judge, for uncontested estates with a clear will or clear heirs. Formal probate goes before the District Court, which has exclusive jurisdiction over contested or supervised matters.

Either the county Probate Court, for uncontested informal proceedings, or the Probate Division of the District Court, which has exclusive jurisdiction over formal proceedings under NMSA 45-1-302.

Does New Mexico's Probate Court use elected judges?

Yes — each county has an elected probate judge who is not required to be a lawyer, handling uncontested informal matters. Anything formal, supervised, or contested moves to the District Court instead.

What's the difference between a personal representative named as executor and one appointed as administrator in New Mexico?

A personal representative named in a will is often called an executor; one appointed when there's no will is called an administrator.
