To find who owns the mineral rights in Texas under a specific tract, work backward through the deed records for the county where the land sits: pull the property’s legal description, check the county appraisal district for a separate mineral account, and then trace the chain of title in the county clerk’s grantor-grantee index one transfer at a time until you reach the point the minerals were severed from the surface or the original land grant. Because Texas treats the mineral estate and the surface estate as two separate sets of rights, the person who owns the house may not own what is underneath it, and the two chains of title can diverge permanently once a seller reserves the minerals.1Railroad Commission of Texas.

Gather the Legal Description First
A street address will not get you far at the courthouse. You need the survey name, the abstract number, and, for platted subdivisions, the lot and block numbers. That information usually appears on the surface deed, on tax statements from the county appraisal district, or in older title documents. Without it, you cannot locate the right records.
What you are building is a chain of title for the minerals: a timeline of every person or entity that has owned the mineral interest, from the original land grant to today. Each link is a recorded document. A few types matter most:
- Warranty deeds are the standard document used to sell land. Read them closely. If the seller kept the minerals, the deed will contain a reservation clause, and missing that clause is the easiest way to lose the chain.
- Mineral deeds transfer only the mineral interest and start a separate ownership chain from the point of severance forward.
- Royalty deeds convey the right to receive a share of production revenue but not the right to lease or explore. A royalty deed holder cannot sign a lease.
- Probate records determine who inherited a mineral interest when the owner died. Missing probate filings are one of the most common reasons a chain of title goes cold.
Once a landowner sells the surface but reserves the minerals, that reservation is a permanent severance. From that point on, the mineral interest has its own chain of title that may never again overlap with the surface ownership records.
Check the County Appraisal District First
Before spending a day at the courthouse, look up the property on the county appraisal district’s website. Appraisal districts separately assess mineral interests for property tax purposes, so they maintain records identifying who currently owns mineral interests in each tract. Someone has to receive the tax bill. Many districts have searchable online databases.
A quick search can tell you whether a separate mineral account exists and whose name is on it. That will not give you the full chain of title, but it does give you a current name to work backward from at the county clerk’s office. That is far easier than trying to trace forward from a land grant issued in the 1800s.
One caution. Appraisal district records reflect the information reported to them. If a mineral interest was inherited but the heir never updated the records, the listing may still show the deceased owner. Treat it as a lead, not a legal determination of ownership.
Trace the Chain in the County Clerk’s Records
The county clerk’s office in the county where the land sits is the official repository for recorded property documents. Texas law requires each county clerk to maintain an alphabetical cross-index of grantors (sellers) and grantees (buyers) for every recorded deed, mortgage, and other real property instrument.2State of Texas. Texas Local Government Code 193.003 – Index to Real Property Records This grantor-grantee index is the main research tool.
Start with the name of the current surface owner (or the current mineral owner from the appraisal district) listed as the grantee. The index will point you to the deed that transferred the property to them, recorded by volume and page number or by instrument number. Read that deed carefully for any mineral reservation. Then take the grantor’s name from that same deed and look them up as a grantee in an earlier transaction. Step backward through time, one transfer at a time. Each document you pull may confirm the minerals passed with the land or reveal the moment they were carved out.
This is where most people hit a wall. A single mineral interest severed in 1940 could have been split among four heirs in 1965, then partially sold to a company in 1982. Every branch has to be followed separately. For land in counties with a long history of oil production, like those in the Permian Basin, mineral chains with dozens of branches are common.
When you find a relevant document in the index, the clerk’s staff can pull the original for you to examine. Official copies cost $5 for the clerk’s certificate plus $1 per page.3State of Texas. Texas Local Government Code 118.011 – Fees for Services by County Clerk On a long search, fees add up. Take notes on what you find before deciding which documents to pay to copy.
Online Records
Many Texas counties now offer online access to their property records through the county clerk’s website, often supporting the same grantor-grantee searches you would run in person. Coverage varies. Some urban counties have digitized documents going back decades; some rural counties have only recent filings online. Online searches save a trip for newer transactions, but older documents often still require an in-person visit.
Go Back to the Original Grant at the General Land Office
For properties with very old roots, you may need to go all the way back to the original land grant. The Texas General Land Office maintains a digitized archive of more than six million documents, including Spanish and Mexican land grants, Republic of Texas patents, and early statehood surveys.4Texas General Land Office. Archives and Heritage The GLO’s Land Grant Database is searchable online.
These records matter because of a historical quirk. Texas retained mineral rights under millions of acres originally set aside for public schools and other state purposes. If your property sits on former public school fund land, the state may still own the minerals no matter how many times the surface has been sold. The GLO’s records can tell you whether the original grant or patent reserved minerals to the state. If it did, private ownership of the minerals effectively starts and ends there, and any leasing goes through the GLO rather than a private owner.
Use the Railroad Commission for Context
The Texas Railroad Commission maintains a Public GIS Viewer that displays oil and gas well locations, drilling permits, and production data on an interactive map.5Railroad Commission of Texas. Public GIS Viewer Active wells on or near your property tell you someone has already leased the mineral rights and an operator is producing. The RRC’s records can identify the operator, which gives you another thread to pull. The operator likely has a division order on file listing every interest owner in the well.
The RRC regulates oil and gas operations. It does not track who owns mineral rights. Use it for context, not as proof of ownership.
Producing Wells and Division Orders
If minerals on the property are already being produced, a division order may already exist that maps out every owner’s fractional interest. Under Texas law, a division order is an agreement signed by each interest owner that directs the operator to distribute production revenue according to specified decimal shares.6Texas Public Law. Texas Natural Resources Code Section 91.401 – Definitions It includes a description of the property, the fractional interest claimed by each owner, the type of interest, and each owner’s name, address, and taxpayer identification number. For research purposes, that means an operator’s file may contain a ready-made ownership breakdown for the tract.
Unclaimed Royalties as a Research Signal
Mineral royalties that go unclaimed for more than three years are reported to the Texas Comptroller’s Unclaimed Property Program under Texas Property Code Chapter 75. The Comptroller holds those funds indefinitely until the rightful owner comes forward, and there is no deadline to file a claim.7Texas Comptroller. FAQs About Unclaimed Property
Unclaimed royalties matter for a mineral search because they signal an ownership gap. If your research shows that a deceased relative owned mineral rights, search the Comptroller’s database at claimittexas.gov. The search works by owner name, and the name on file is whatever name the producing company used when it reported the funds.
To claim held funds, you will need to prove you are the rightful owner or heir. The Comptroller may require probate records, letters testamentary, death certificates, or an affidavit of heirship. Most of those can be obtained from the county clerk where the owner died or where probate was filed.8Texas Comptroller. Forms and Resources After recovering the funds, contact the producing company directly to update your information so future royalties reach you without going through the unclaimed property process again.
When To Bring In a Professional
You can handle a basic search yourself when the property has a short history and the minerals have never been severed. Some situations genuinely require professional help: chains stretching back a century or more, interests fragmented among many heirs, gaps in the recorded documents, or any transaction that needs a legally binding ownership determination.
An independent landman is a specialist in researching property records and tracing mineral title. They work in county clerk offices for a living and can navigate records that would take an untrained person weeks. Landmen typically charge a daily rate, and experienced contract professionals commonly earn several hundred dollars per day depending on the complexity of the project. A straightforward title search on a single tract may take only a few days; a property with fractured ownership across multiple counties can take weeks.
Once the research is compiled, an oil and gas attorney can prepare a title opinion. That is a formal legal document stating who owns the mineral rights, in what fractions, and whether any title defects exist. Title opinions are typically required before an operator will drill or before mineral rights are sold. If a dispute exists or a quiet title action is needed, the attorney handles the litigation as well.
If Someone Else Owns the Minerals
If the search reveals that someone else owns the minerals under your land, know that Texas law gives the mineral estate a dominant position over the surface estate. The mineral owner or their lessee has the right to enter the surface and use as much of it as is reasonably necessary to explore for and produce minerals, and no written agreement from the surface owner is required before drilling begins. Surface owners have some protection under the accommodation doctrine, and many mineral lessees voluntarily negotiate surface use agreements addressing roads, well pad placement, water use, and compensation for surface damage. Knowing who owns the minerals is the starting point for any of those conversations.
