The split estate — Texas's most important real estate concept
In Texas, land ownership is often described as a "bundle of sticks" — a collection of separate rights that can be owned by different people. The two most important are surface rights and mineral rights.
Surface rights give you the right to use the land — to build on it, farm it, hunt it, and live on it. When you buy a piece of Texas land, you almost always receive the surface rights.
Mineral rights give you ownership of what's underground — oil, gas, coal, uranium, metals, and other minerals. Mineral rights can be sold, leased, or inherited separately from the surface. In Texas, once mineral rights are severed from the surface, they run with whoever owns them — not with the land itself.
This separation is called a split estate — and it's extremely common in Texas. Decades of oil and gas activity have resulted in mineral rights being carved off, subdivided, and passed through estates across most of the state. It is entirely possible — and common — to buy land in Texas and own zero percent of the minerals beneath it.
Why this matters more in Texas than anywhere else
Texas has no forced pooling law, strong private mineral ownership traditions, and one of the most active oil and gas industries in the world. The Permian Basin, Eagle Ford Shale, and other formations sit under millions of acres of private land.
If you own minerals and oil or gas is discovered or already being produced beneath your property, you're entitled to royalty payments — typically 12.5% to 25% of production value. On productive acreage, this can be worth far more than the surface land itself.
Conversely, if someone else owns the minerals under your land and they have a valid lease, they have the legal right to access your surface — to drill, run pipelines, and operate equipment — with limited obligation to you as the surface owner. Texas law heavily favors mineral owners in disputes with surface owners.
The accommodation doctrine: In Texas, mineral owners have the dominant estate — they have the right to use as much of the surface as "reasonably necessary" to extract minerals. Surface owners cannot block mineral development. The accommodation doctrine requires mineral owners to use alternative methods if a reasonable alternative exists that won't impair mineral development — but this protection for surface owners is limited and often disputed.
How to find out what you own
Before you close on any Texas land purchase, you need to know the mineral ownership situation. Here's how to find out:
Read the deed carefully
The deed conveying property to you should specify whether mineral rights are included. Language like 'save and except all minerals' means they're not included. 'Together with all minerals' means they are. If the deed is silent on minerals, Texas law generally conveys whatever mineral interest the seller owned — which may be nothing if they were already severed.
Order a title search or mineral report
A title company or landman (mineral research specialist) can search the county deed records and trace mineral ownership. This is called a mineral title opinion or run sheet. Cost typically $500–$2,000 depending on depth of search. Worth every dollar on any significant purchase.
Search county deed records yourself
Most Texas counties have deed records online through their county clerk. Search the property legal description for any deed that mentions minerals, reservations, or exceptions. Look for language reserving minerals to a prior owner.
Check for existing oil and gas leases
The Texas Railroad Commission (rrc.texas.gov) maintains records of all oil and gas leases, permits, and production in Texas. Search by county and legal description to see if there's active or historic production on or near your property.
Common mineral ownership scenarios
| Scenario | What it means |
|---|---|
| Full mineral ownership | You own surface and 100% of minerals. Best case. Rare on land with any oil/gas history. |
| Partial mineral ownership | Prior owner reserved some fraction (e.g. 50%). You receive royalties on your share only. |
| No mineral ownership | Minerals were severed long ago. You own the surface only. Mineral owner can lease to oil companies. |
| Existing oil and gas lease | Minerals are leased to an operator. Drilling may occur. You have limited surface rights recourse. |
| Executive rights only | You can lease the minerals but don't receive royalties — royalties go to non-participating royalty owners. |
Should you pay more for minerals?
If a property includes minerals in an active or prospective oil and gas area, they can be worth significant money. Buyers sometimes negotiate separately for mineral interests — or sellers price minerals into the land price.
In areas with no realistic oil and gas potential — much of East Texas timber country, for example — minerals may have little practical value. In South Texas Eagle Ford country or West Texas Permian Basin areas, minerals can be worth multiples of the surface value.
A mineral appraisal by a qualified petroleum engineer or landman can help you understand what the minerals under a specific property are worth before you negotiate.
Surface owner protections in Texas
Texas surface owners have limited but real protections when mineral development occurs on their property:
- Surface Damage Act. Requires oil and gas operators to compensate surface owners for actual damages to crops, timber, fences, and water wells caused by drilling and production operations.
- Water well protection. Operators must avoid damaging water wells and may be required to provide alternative water sources if drilling damages a surface owner's well.
- Notice requirements. In some circumstances operators must provide advance notice before entering and commencing surface operations.
- Surface use agreements. Negotiating a surface use agreement with the mineral lessee before drilling begins is the most effective way to protect your interests — specifying road locations, setbacks from structures, reclamation requirements, and compensation terms.
Bottom line
Never assume you own the minerals when you buy Texas land. Find out before you close — not after. A mineral title search is one of the most valuable things you can spend $500–$2,000 on in a land transaction.
If you don't own the minerals and the area has oil and gas potential, negotiate a surface use agreement with any operator who approaches you about access. You have limited legal leverage in Texas, but a negotiated agreement gives you real protections that the law alone doesn't.
And if you do own minerals — in an active area — don't lease them without consulting a landman or oil and gas attorney. Royalty rates, Pugh clauses, surface use restrictions, and lease terms matter enormously to the value you'll receive.
