Owning mineral rights means owning what's under the ground, not what's on top of it, and that split is the first thing every Texas landowner should understand.
Texas law treats the mineral estate as a distinct property interest from the surface estate, and they can be owned by different people entirely. If you own mineral rights, you own the oil, gas, and other minerals beneath a tract, along with certain legal rights tied to that ownership, whether or not you own or ever set foot on the surface above it.
This is the broadest category of interest an owner can hold. Royalty interests, working interests, and overriding royalties are all pieces carved out of, or held alongside, the full mineral estate, which is why understanding what a full mineral interest includes matters before you start sorting out which specific piece you actually own.
What full mineral ownership includes
Owning the mineral estate typically bundles several rights together: the right to explore and produce, the right to receive bonus and royalty payments from a lease, the right to negotiate and sign leases (called executive rights), and the right to receive delay rentals if applicable. A full, undivided mineral owner controls all of these. Many owners, especially through inheritance, end up holding some but not all of these rights, because prior owners severed pieces off over the years.
That's why the first step with any mineral interest is figuring out exactly which of these rights your deed actually conveys, not assuming a full bundle.
How mineral ownership gets divided over time
A mineral owner can lease their interest to an operator, which creates a working interest for the operator and leaves the mineral owner with a royalty interest under the lease terms. A mineral owner can also sell off a royalty interest, an overriding royalty, or a fraction of the mineral estate itself, all while retaining other pieces. Over multiple transactions and generations, a single original tract's mineral rights can end up scattered across several different interest types and owners, which is normal and not a sign anything went wrong.
Executive rights: the power to lease
Executive rights, the authority to negotiate and sign an oil and gas lease on the minerals, are sometimes separated from the rest of the mineral interest, particularly in older deeds. If you own minerals but not executive rights, someone else controls leasing decisions even though you receive royalty income under whatever lease they sign. Check your deed carefully on this point, since it affects what control you actually have.
Selling a full mineral interest versus a carved-out piece
Selling a full mineral interest generally brings a different, often higher, value than selling just a royalty or override, because the buyer gets the complete bundle of rights, including future leasing control. If you hold a full mineral interest and are weighing a sale, understand that buyers will price in that leasing control and any future bonus potential, not only current or projected royalty income.
How courthouse records confirm what you actually hold
The clearest way to confirm exactly what mineral rights you hold is a chain-of-title review at the county clerk's office, tracing every conveyance, reservation, and severance affecting the tract back to a clean starting point. This sounds tedious, and it can be, but it's the only way to be certain your deed's language matches what you believe you own, since older deeds sometimes use language that reserves or excepts pieces in ways that aren't obvious on a casual read.
A landman or title attorney doing this work will flag anything unusual, a prior royalty carve-out, a term interest that's already expired, or a co-tenant nobody in the current family remembers, before it becomes a problem during an actual sale.
Texas Owner Questions
What's the difference between mineral rights and royalty interests?
Mineral rights are the full underlying ownership, including the right to lease and receive bonus payments. Royalty interests are a narrower right to a share of production revenue, often created when a mineral owner leases their interest.
Can you own the surface of your land without owning the minerals under it?
Yes. Texas allows the surface and mineral estates to be owned separately, often called a severed estate, and this happens routinely through prior sales or reservations in the chain of title.
How do you find out exactly what mineral rights you own?
Your deed, along with the full chain of title at the county clerk's office, will show what was conveyed to you and whether any prior owner reserved or sold off pieces like royalty or executive rights.
Is it better to sell your full mineral interest or just lease it?
It depends on your goals. Leasing keeps you in line for royalty and future bonus payments with ongoing uncertainty; selling converts the interest to cash now. Neither is automatically better; it depends on your own situation.
Can you sell just your executive rights and keep the rest of the mineral interest?
Yes, executive rights can be conveyed separately from the rest of the mineral estate, though it's a less common transaction and should be structured carefully with clear deed language.
