Real property has two estates: the surface estate (the land) and the mineral estate (the oil and gas beneath it). When they are owned by different parties, that is a split or severed estate — common in Texas. The mineral estate is generally dominant, giving the mineral owner reasonable rights to use the surface to produce minerals. Knowing which estate you own is essential before leasing or selling.
One of the most common sources of confusion in oil and gas country is the difference between mineral rights and surface rights. They are two separate forms of property ownership, and one tract can have different owners for each. This guide explains the split estate in plain English and what it means for mineral and surface owners.
Two Separate Estates
Real property can be divided into a surface estate and a mineral estate. The surface estate is the land itself — the ground you build on, farm, or graze. The mineral estate is the oil, gas, and other minerals beneath it, along with the rights to explore for and produce them. These two estates can be owned by the same person or, very commonly in Texas, by different people.
What Is a Split Estate?
When the surface and the minerals are owned by different parties, that is called a split or severed estate. It happens when a previous owner sells or reserves the minerals separately from the land. As a result, you can own the surface of a property without owning the minerals beneath it — or own valuable minerals under land whose surface belongs to someone else.
In a split estate, owning the surface does not mean you own the minerals, and owning the minerals does not mean you own the surface.
Why the Mineral Estate Is "Dominant"
Under long-standing Texas law, the mineral estate is generally considered the dominant estate. This means the mineral owner (or their lessee) has the right to make reasonable use of the surface as necessary to access and produce the minerals. Courts also recognize the accommodation doctrine, which can require the mineral owner to reasonably accommodate existing surface uses in certain circumstances. These are technical legal matters best discussed with an attorney.
Why This Matters for Owners
- You may own minerals without owning the surface above them — and they can still be valuable.
- You may own the surface but not the minerals, meaning others can develop beneath you.
- Selling the surface does not automatically sell the minerals, and vice versa.
- Knowing exactly which estate you own is essential before leasing or selling.
Confirming and Selling Your Minerals
If you are unsure whether you own the minerals, the surface, or both, county deed records and a title professional can help you confirm it. ARB buys mineral interests specifically — including across the Permian Basin — and can help identify your mineral interest as part of a free, no-obligation valuation with no fees to sellers.
Key Takeaways
- Surface rights (the land) and mineral rights (what is beneath it) are separate estates.
- A split or severed estate means the surface and minerals have different owners.
- In Texas, the mineral estate is generally dominant over the surface estate.
- Selling the surface does not sell the minerals, and vice versa.
- Confirm exactly which estate you own before leasing or selling.
Frequently Asked Questions
What is the difference between mineral rights and surface rights?
Surface rights are ownership of the land itself; mineral rights are ownership of the oil, gas, and minerals beneath it, including the right to produce them.
What is a split estate?
A split or severed estate is when the surface and the minerals of the same tract are owned by different parties, often because a prior owner sold or reserved the minerals separately.
Can I own minerals without owning the land?
Yes. Minerals can be severed from the surface, so you can own valuable mineral rights under land whose surface belongs to someone else.
Why is the mineral estate called dominant?
Under Texas law, the mineral owner generally has the right to make reasonable use of the surface to access and produce the minerals. The accommodation doctrine can modify this; consult an attorney for specifics.
How do I know if I own the minerals or just the surface?
County deed records and a title professional can confirm it. ARB can also help identify your mineral interest as part of a free valuation.
