You inherited an interest in New Mexico, or you are about to. Here is what the state actually requires to put it in your name, what can take it away if you do nothing, where the money goes when the operator cannot find you, and the order to do things in. Written by a mineral buyer who pays for the probate on a committed deal, so read it with that in mind.
Updated November 2026. Written by Stephen Clayman, career landman and owner of Berlin Royalties. Statutes were checked against primary sources; this is general information from a buyer, not legal advice, and the state-specific details are the reason to call a New Mexico attorney, not a substitute for one.
Yes. New Mexico's affidavit of successor in interest is personal property only and does not apply to any estate holding real property, and the state has no heirship affidavit statute. Inherited minerals pass through probate with a personal representative's deed recorded in each county, and an out-of-state estate needs ancillary proceedings; Allen v. Amoco held a mineral transfer without them invalid.
Minerals are real property. NMSA 45-3-1201, the affidavit of successor in interest, covers estates under $50,000 and personal property only; an estate with any real property does not qualify. NMSA 45-3-1205 is the surviving spouse's community property homestead affidavit, not a general heirship affidavit, and New Mexico has none.
The route is a probate, formal or informal, with a personal representative's deed of distribution recorded in each county where the minerals sit. A nonresident decedent's estate needs a formal ancillary appointment under NMSA 45-4-207 or recognition of the out-of-state appointment; the courts have held a mineral transfer made without ancillary proceedings invalid.
Yes. New Mexico adopted the Uniform Real Property Transfer on Death Act, NMSA 45-6-401 to 45-6-417. The deed must be recorded before death. No mineral exclusion.
New Mexico does not appear on the dormant mineral statute tables and we found no New Mexico lapse statute; confirm with counsel. Unused severed minerals in Lea and Eddy counties are among the most valuable in the country, so a buyer's letter claiming an interest 'may have lapsed' should be treated with suspicion.
The Oil and Gas Proceeds Payment Act, NMSA 70-10-1 to 70-10-6: first payment within six months after the first day of the month following first sale, then within 45 days after the end of the month the payor is paid. Suspended funds earn the Dallas Federal Reserve discount rate plus 1.5 points, and late payment after the payor has the owner's information bears an 18 percent per year penalty, excused for good-faith reliance on a New Mexico title opinion, title doubt, refusal to sign a reasonable division order, or a balance under $100. Our letter generator writes the statutory demand, and the full state table is on royalty payment laws by state.

No New Mexico estate or inheritance tax. New Mexico is a community property state, which decides what the decedent owned before anyone decides who inherits it. Inherited minerals take a federal stepped-up basis. The arithmetic is on our capital gains and depletion page, and a date-of-death appraisal is what documents the basis.

Not by affidavit. The NMSA 45-3-1201 affidavit excludes any estate holding real property. A transfer on death deed recorded before death avoids probate; after death, a probate with a recorded personal representative's deed is the route.
No. Allen v. Amoco held a transfer without New Mexico ancillary proceedings invalid. An ancillary appointment under NMSA 45-4-207 or recognition of the foreign appointment is required.
18 percent per year under NMSA 70-10-5 once the payor has the owner's information, with exceptions for title doubt and reliance on a New Mexico title opinion.
