New Mexico mineral estates routinely mix federal, state, and fee interests, each with its own transfer process. Picture a typical estate: a retired schoolteacher in Albuquerque inherits her father's minerals after he passes. The first surprise is that "his minerals" turn out to be three different things — a fee interest under a fee tract, a federal oil and gas lease assignment from a parcel managed by the BLM, and a State Land Office lease on another section. Each piece transfers under a different process, takes a different timeline, and lands at a different desk for approval. New Mexico probate looks easy on the surface and then, somewhere around the BLM's Form 3000-3, gets complicated in a hurry.
New Mexico adopted the Uniform Probate Code (UPC), which provides a streamlined probate framework compared to many other states. The UPC's informal probate process is well-suited for mineral estates where the title is clear and the heirs are in agreement.
However, New Mexico has unique complications: a significant percentage of minerals in the state are federally owned (BLM) or state-owned (State Land Office), creating mixed ownership patterns. Fee minerals, federal minerals, and state minerals all have different transfer requirements and procedures.

Informal probate is the most common method in New Mexico. It does not require a court hearing — the personal representative files an application with the probate registrar, and if the application is in order, the registrar issues letters testamentary or letters of administration.
The personal representative then has authority to manage estate assets, including mineral interests. After debts are paid and the waiting period expires, the personal representative can distribute minerals to the beneficiaries via a personal representative's deed.
Informal probate is typically completed in 6-12 months, though the letters can be issued within days of filing.
New Mexico allows a simplified closing statement procedure for estates where all assets (including minerals) total less than $200,000 in value, or where the estate is solvent and all beneficiaries agree to the distribution.
The personal representative files a closing statement with the court, distributes the assets, and the estate is closed without a final hearing. This is faster than formal closing and is appropriate for most mineral estates in New Mexico.
A significant portion of New Mexico's mineral acreage is owned by the federal government (managed by the Bureau of Land Management) or the state (managed by the New Mexico State Land Office). These minerals cannot be inherited in the traditional sense because they are not privately owned.
What can be inherited is a lease on federal or state minerals. Federal oil and gas leases are assignable and pass through the estate, but the assignment must be approved by the BLM. This process can take several months and requires specific forms (Form 3000-3 for BLM assignments).
State mineral leases are similarly assignable but require approval from the State Land Office. The process is generally faster than BLM but still requires documented proof of authority (letters testamentary or a court order).
For fee minerals (privately owned minerals not subject to federal or state ownership), the standard New Mexico probate process applies.
When handling New Mexico mineral estates, attorneys should:
Distinguish between fee minerals, federal lease interests, and state lease interests — each has a different transfer process.
File letters testamentary or administration with each county where fee minerals are located.
Notify the BLM and/or State Land Office if the estate includes federal or state lease interests, and begin the assignment process early as it can be slow.
Check for suspended royalties with operators — New Mexico operators are required to escrow suspended royalties, and there may be meaningful funds waiting to be released once title is cleared.
Coordinate with operators to update division orders after the estate is distributed.
If the heirs wish to sell fee mineral interests, Pointer Minerals can provide an offer and close on a timeline that works with the probate process. We are experienced with New Mexico's mixed ownership patterns and can identify which interests are fee, federal, and state.
Informal probate letters can be issued within days of filing. The full administration typically takes 6-12 months, including the creditor notice period. Summary closing can be completed in 4-6 months if all beneficiaries agree.
Yes, federal oil and gas leases are assignable and pass through the estate. However, the assignment must be approved by the Bureau of Land Management, which requires filing Form 3000-3 and providing proof of authority (letters testamentary or court order). BLM processing times vary but can take several months.

Ohio is one of the few producing states where inherited mineral rights can genuinely be lost to the surface owner through inaction. The Dormant Mineral Act sets out exactly how that happens — and exactly how heirs can stop it. If your family once owned minerals in eastern Ohio, the time to check is before a notice arrives, not after.
Mississippi mineral interests — Tuscaloosa Marine Shale royalties along the southwestern fairway, legacy Mississippi Salt Basin oil and gas across the south, and shallow conventional production scattered statewide — pass through estate proceedings under the Mississippi Code (Title 91) in the chancery courts. The defining institutional feature of Mississippi mineral practice is the chancery-court system itself: equity-rooted, county-based, and procedurally distinct from the common-law probate courts found in most other states.
Arkansas mineral interests — dormant Fayetteville Shale royalties across the Arkoma fairway, legacy Smackover oil and brine in the south, and the contemporary lithium-extraction pivot in the Smackover — pass through probate under Title 28 of the Arkansas Code Annotated. The defining feature of Arkansas mineral practice is the gap between the play’s 2008–2016 Fayetteville heyday and its current low-activity baseline, which routinely surfaces unaddressed succession gaps in inherited interests.
West Virginia mineral interests — dominantly Marcellus and Utica royalties in the northern panhandle and north-central counties — pass through estate proceedings under Chapters 41 (wills) and 44 (decedents’ estates) of the West Virginia Code. The defining feature of WV mineral practice is the layered nineteenth-century severance history: an estimated 1.3 million distinct mineral interests, many traceable to severances recorded in the 1880s–1910s, generate disproportionate curative volume per estate.
