How to Find Out If You Own Mineral Rights in Texas

It is a question that comes up constantly. "Do I own mineral rights on my property?"

Sometimes it is prompted by a letter in the mail from a buyer or a leasing company. Sometimes a family member mentions something about "oil money" from decades ago. Sometimes it is just curiosity. You own land in Texas and you have heard that minerals can be valuable.

The answer is: maybe. Finding out requires looking in the right places.

Why This Is Not a Simple Yes or No

Key Takeaway: To determine if you own mineral rights in Texas, you must trace the chain of title in the County Clerk's deed records back through prior conveyances to confirm whether a prior owner severed the mineral estate from the surface estate. County appraisal district tax rolls only reflect producing wells, not non-producing severed minerals.

In most states, when you buy land, you get everything. Surface and minerals. Texas is different. Texas has allowed mineral rights to be severed from the surface estate since the Republic days. That means:

• You can own the surface of a property and have zero mineral rights.
• Someone else can own the minerals beneath your land.
• The mineral estate can be split among dozens of owners, each holding a fractional undivided interest.
• Minerals can be inherited, sold, leased, or reserved independently of the surface.

This is why you cannot just look at your property deed and know the answer. The mineral ownership history might involve 50+ transactions over 100+ years, each one potentially carving off a piece of the mineral estate.

Method 1: Check Your Deed

Start with your own deed. The document you received when you purchased the property or inherited it. Look for these phrases:

"Together with all mineral rights" or "including all oil, gas, and other minerals." This means the seller intended to convey minerals to you. Good sign. But you still need to verify that the seller actually owned them.

"Subject to all reservations and exceptions of record." This is the most common language. It means your deed is subject to whatever mineral reservations prior owners made. It does not mean you own the minerals. It means you need to look further back.

"Reserving unto Grantor all oil, gas, and other minerals." The seller explicitly kept the minerals. You own the surface only.

"Less and except" a specific mineral interest. Partial reservation. The seller kept some fraction and conveyed the rest.

If your deed is ambiguous (and many are), the only way to know for certain is to trace the chain of title backward through every prior conveyance.

Method 2: Search the County Appraisal District

Every Texas county has a Central Appraisal District (CAD) that maintains property tax records. Most have online search tools.

Search by your name at your county's CAD website. Look for separate mineral interest entries. In many counties, mineral interests are appraised and taxed separately from the surface. If you see a line item for "mineral interest" under your name, that is a strong indicator.

Then search by the property address and look for other names listed as mineral owners on the same tract. If the mineral interest is listed under a different name, those are the mineral owners.

One caveat: not every county appraises minerals separately, and the CAD records do not always reflect the full chain of title. They are a useful starting point. They are not a final answer.

Method 3: Search the County Clerk's Records

This is the definitive source. Every mineral deed, mineral reservation, oil and gas lease, assignment, and heirship affidavit is recorded with the county clerk. These records go back over a century in most Texas counties.

Search by name in both the grantor (seller) and grantee (buyer) indexes. Look for instrument types like "Mineral Deed," "Royalty Deed," "Oil and Gas Lease," "Assignment," and "Reservation."

Here is where it gets real. Texas has 254 counties. Not all of them have online records. The ones that do may only go back to the 1990s or 2000s digitally. The critical mineral transactions in your chain might have happened in the 1940s or 1950s. The older records exist. They are just in books at the courthouse.

Volume matters too. In the counties I work regularly, there can be hundreds of thousands of recorded instruments per county. Missing one mineral reservation from 1953 can completely change the ownership picture. It is not a casual search. It is forensic.

Method 4: Check State Databases

A few state-level resources can help.

Texas Comptroller, Unclaimed Property Search at ClaimItTexas.org. If mineral royalties were paid but never cashed, the funds may be sitting with the state. Search by your name and your ancestors' names.

Texas Railroad Commission at rrc.texas.gov. Search for active wells, operators, and production in your county. If there is production on or near your tract, it is worth investigating whether you hold a mineral interest.

Texas General Land Office at glo.texas.gov. For state-owned minerals and historical land grants. If your land was originally a Republic of Texas patent, the GLO has those records.

What If You Find Something?

If any of these searches turn up evidence that you or your family may own mineral rights, here is what to do next.

Document what you found. Screenshot the CAD entry, note the instrument numbers from the clerk's records, save any old deeds or check stubs.

Identify the chain. The key question is not just whether minerals were once in the family. It is whether they were conveyed away at some point. A mineral deed from 1960 might have transferred the interest to a third party. You will not know until you run the full chain.

Check for production. If there are active wells, you may be owed royalties. If the operator does not have you in their division order, the money could be sitting in suspense. I have seen this dozens of times: an heir who did not know they owned minerals, while royalty checks accumulated in an operator's suspense account for years.

Get professional help if needed. Landmen run title every day. When title involves multiple generations, split interests, missing probate, or minerals in more than one county, a professional review can help sort out the records.

The Bottom Line

Finding out whether you own mineral rights is not hard. But it does require digging through records that most people do not know exist. The county clerk's office is the authoritative source. The CAD is a useful shortcut. Your own deed is the starting point.

After working across dozens of counties, I have seen mineral ownership surprise people in both directions. Some think they own minerals and do not. Others, often heirs who never thought to check, find they have held a producing interest for years without collecting royalties.

The only way to know is to look. If you do not want to do it yourself, that is what I am here for.
