Mineral Rights vs. Surface Rights: What Every Buyer Needs to Know

By Richard Partin, Managing Member, Texas State Royalties LLC Fort Worth, Texas | Published: October 6, 2026 | Last Updated: October 16, 2026

My family has been acquiring and operating mineral interests in Comanche and Eastland Counties for multiple generations. I studied biology and chemistry at UT Arlington and now facilitate acquisitions of producing mineral and royalty interests for qualified buyers across Texas through Texas State Royalties LLC. The most common title defect I encounter in Comanche and Eastland County acquisitions is unestablished heirship — a direct consequence of the split-estate history of Texas land ownership. Understanding the distinction between mineral rights and surface rights is the foundation of every responsible acquisition.

Quick Answer: In Texas, a single tract of land can be divided into two separate estates: the surface estate (everything above ground) and the mineral estate (oil, gas, and other subsurface resources). When these are owned by different parties, the property is called a split estate. The mineral estate is the dominant estate under Texas law, meaning the mineral owner's right to develop the subsurface generally takes precedence over the surface owner's preferences. Buyers of mineral interests acquire rights in the subsurface only — not the surface.

When most people think about owning land, they think about a single, unified ownership — one deed, one owner, one set of rights. In Texas, that assumption is frequently wrong.

Texas law recognizes that a single tract of land can be divided into two entirely separate estates: the surface estate and the mineral estate. The surface estate covers everything above the ground — the soil, the structures, the water on the surface, and the right to use the land. The mineral estate covers everything below — the oil, gas, coal, sulphur, and other subsurface resources that may lie beneath that same tract, as defined under Texas Property Code § 1.002.

These two estates can be owned by different people. They can be bought, sold, inherited, and transferred independently of each other. And in Texas, they frequently are.

How Are Mineral Rights Severed from Surface Rights in Texas?

The separation of mineral rights from surface rights is called severance. Once severed, the two estates exist independently and can be conveyed separately in perpetuity.

Severance happens in one of two ways:

Reservation in a deed. When a landowner sells the surface, they can reserve the mineral rights for themselves. The deed conveys the surface estate to the buyer but explicitly retains the mineral estate with the seller. From that point forward, the surface and minerals are separate estates with separate owners.

Conveyance of the mineral estate alone. A landowner can also sell or transfer only the mineral rights while retaining the surface. The deed conveys the mineral estate to the buyer, and the seller retains the surface.

In either case, once the severance occurs, it is permanent. Future buyers of the surface acquire only the surface estate. Future buyers of the mineral estate acquire only the minerals. Neither transaction automatically reunites the two estates.

In my experience examining title chains in Comanche and Eastland Counties, mineral reservations in ranch and farm deeds from the early and mid-twentieth century are extremely common — and the reserved mineral interests have often passed through multiple generations of heirs without a formal probate proceeding. The result is unestablished heirship: the mineral estate exists, but the current ownership cannot be confirmed without a heirship proceeding or affidavit. This is the most common title defect I encounter in acquisitions in those counties, and it is a direct product of Texas's long history of mineral severance.

What Is a Split Estate and Why Does It Matter for Buyers?

When the mineral estate and the surface estate are owned by different parties, the property is called a split estate. Split estates are extremely common in Texas. Decades of oil and gas activity, combined with Texas's long history of mineral reservations in ranch and farm deeds, mean that a large percentage of Texas land has severed minerals.

For a buyer purchasing surface land in Texas — a ranch, a farm, a rural tract — the existence of a split estate has significant practical implications:

The surface buyer does not own the minerals. If oil or gas is discovered beneath the land, the surface owner has no right to the royalty income. That income belongs to the mineral estate owner. I have seen buyers in Palo Pinto and Comanche Counties discover after closing that prior reservations in the deed chain had reduced their stated mineral ownership by 25% or more — interests they believed they were acquiring that had been reserved by prior owners decades earlier.

The mineral owner has the right to access the surface. Under Texas law, the mineral estate is the dominant estate. The mineral owner — or an operator acting under a lease from the mineral owner — has the right to use as much of the surface as is reasonably necessary to develop the minerals. This right exists even without the surface owner's consent.

The surface owner cannot prevent mineral development. A surface owner who does not own the minerals generally cannot block an operator from drilling on the property, subject to applicable Texas Railroad Commission regulations and the terms of any surface use agreement.

For buyers of surface land in Texas, understanding whether the minerals have been severed is an essential part of due diligence. For buyers of mineral interests, understanding the split estate clarifies exactly what they are acquiring — and what rights they hold relative to the surface owner.

How Do You Determine Whether Minerals Have Been Severed?

The only reliable way to determine whether the mineral estate has been severed from the surface is to examine the chain of title in the county deed records.

Every deed that has ever conveyed the property — going back to the original patent from the State of Texas — is recorded in the county clerk's office for the county where the land is located. A title examiner reviews this chain of title to identify any deed that reserved or conveyed the mineral estate separately from the surface.

Key things a title search will reveal:

Whether any prior deed reserved the minerals. A reservation clause in any deed in the chain of title severs the mineral estate from that point forward. In Comanche and Eastland Counties, I routinely find reservations buried in deeds from the 1930s through 1960s that are still controlling the mineral ownership today.

Who currently owns the mineral estate. If the minerals were reserved or conveyed, the title search will trace the mineral estate through subsequent conveyances to identify the current owner — including any heirship proceedings or affidavits that established ownership after a mineral owner died without a formal probate.

Whether the mineral estate has been further divided. Mineral interests can be fractionally divided among multiple owners. A title search will identify any such divisions. In my experience, fractional mineral interests in Comanche and Eastland Counties are common — a single tract may have a dozen or more fractional mineral owners, each holding a small decimal interest.

Whether there is an active oil and gas lease. If the mineral estate is currently leased to an operator, the lease will appear in the deed records. The lease terms — royalty rate, primary term, post-production deduction provisions — are critical to evaluating the value of the mineral interest.

For buyers of mineral interests, a title search is not optional — it is the foundation of any responsible acquisition. For buyers of surface land, a title search that includes a mineral review is the only way to know whether the minerals come with the property.

What Is the Dominant Estate Doctrine and How Does It Affect Surface Owners?

Texas law treats the mineral estate as the dominant estate. This means that when the interests of the mineral owner and the surface owner conflict, the mineral owner's rights generally prevail — subject to the accommodation doctrine.

The dominant estate doctrine gives the mineral owner (or an operator acting under a lease) the right to:

• Enter the surface to conduct exploration and drilling operations
• Use as much of the surface as is reasonably necessary for mineral development
• Install roads, pipelines, tanks, and other infrastructure needed for production

This right exists without the surface owner's consent and without compensation, unless a surface use agreement or applicable statute provides otherwise. The Texas Natural Resources Code and Texas common law govern the relationship between mineral and surface owners in the absence of a specific agreement.

The accommodation doctrine provides a limit on the dominant estate. Under the doctrine established in Sun Oil Co. v. Whitaker (1972), an operator must accommodate the existing surface use if there is an alternative method of development that will not substantially interfere with the surface owner's use of the land. The accommodation doctrine does not eliminate the mineral owner's right to develop — it requires the operator to consider whether a reasonable alternative exists.

In practice, the accommodation doctrine is most relevant when a surface owner has an established agricultural or commercial use that would be disrupted by drilling operations. The doctrine is not a veto right — it is a requirement to consider alternatives when they exist.

What Rights Does a Mineral Interest Buyer Actually Acquire?

When a buyer acquires a mineral interest in Texas, they are acquiring rights in the mineral estate — not the surface estate. Specifically, a mineral interest owner holds:

• The right to execute an oil and gas lease with an operator
• The right to receive bonus payments when a lease is signed
• The right to receive royalty payments when production generates revenue under the terms of the lease
• The right to develop the minerals themselves (though most mineral interest owners lease rather than operate)

What a mineral interest buyer is not acquiring:

• Any right to use or occupy the surface
• Any right to the surface owner's improvements or structures
• Any right to surface water or water wells (water rights in Texas are governed separately under the rule of capture and the Edwards Aquifer Authority, depending on the aquifer)

Understanding this distinction is essential for buyers who are new to mineral interest acquisitions. The value of a mineral interest lies entirely in the subsurface — in the oil and gas that may be produced from the acreage and the royalty income that production may generate.

For a detailed explanation of how royalty payments are calculated and what affects the amount a mineral owner receives, see How Royalty Payments Are Calculated.

What Are the Most Common Misconceptions About Mineral Rights vs. Surface Rights?

"If I buy the land, I own the minerals." Not necessarily. In Texas, the minerals may have been severed from the surface decades ago. A buyer who does not conduct a mineral title review may purchase surface land believing the minerals are included, only to discover they were reserved by a prior owner. This is not a rare edge case — it is a routine finding in Texas title examinations, particularly in counties with long oil and gas histories like Comanche, Eastland, Palo Pinto, and Stephens.

"The surface owner can stop the operator from drilling." Generally not. Under the dominant estate doctrine, the mineral owner's right to develop the minerals takes precedence over the surface owner's preferences, subject to the accommodation doctrine and applicable RRC regulations. A surface owner who does not own the minerals has limited ability to prevent development.

"Mineral rights expire if they are not used." Mineral interests in Texas do not expire simply because no development has occurred. An unleased mineral interest remains valid indefinitely. However, an oil and gas lease does have a defined primary term, after which it expires if production has not been established. The mineral interest itself — as distinct from the lease — is perpetual.

"An ORRI is the same as a mineral interest." This is one of the most common due diligence mistakes I see in Fort Worth Basin acquisitions. An overriding royalty interest (ORRI) is carved out of the working interest under a specific lease and expires when that lease expires. A mineral interest is perpetual and survives lease expiration. Buyers who confuse the two may pay mineral-interest prices for a lease-dependent ORRI that could expire within a few years.

"A quitclaim deed conveys the same rights as a warranty deed." Not in Texas. A quitclaim deed conveys only whatever interest the grantor happens to hold — it makes no warranty that the grantor actually owns anything. A warranty deed warrants that the grantor holds good title to the interest being conveyed. For mineral interest acquisitions, the type of deed and the warranties it contains matter significantly.

Key Takeaways

• In Texas, the mineral estate and the surface estate can be owned separately — a separation called severance. Once severed, the two estates are permanently independent and can be conveyed separately in perpetuity, as recognized under Texas Property Code § 1.002.

• A split estate — where the minerals and surface are owned by different parties — is common across Texas, particularly in counties with long oil and gas histories such as Comanche, Eastland, Palo Pinto, and Stephens. Prior mineral reservations in ranch and farm deeds from the early and mid-twentieth century are still controlling mineral ownership today.

• The mineral estate is the dominant estate under Texas law. The mineral owner has the right to use as much of the surface as is reasonably necessary for development, subject to the accommodation doctrine established in Sun Oil Co. v. Whitaker (1972).

• The only reliable way to determine whether minerals have been severed is to examine the full chain of title in the county deed records. In Comanche and Eastland County acquisitions, unestablished heirship — where the mineral estate exists but current ownership cannot be confirmed without a heirship proceeding — is the most common title defect I encounter.

• Prior mineral reservations in Palo Pinto and Comanche County deed chains have reduced stated mineral ownership by 25% or more in acquisitions I have reviewed. Never rely on a seller's representation of mineral ownership without independent title verification.

• When a buyer acquires a mineral interest, they are acquiring rights in the subsurface only — not the surface. The value lies in the potential royalty income from oil and gas production, not in any right to use or occupy the land.

• An overriding royalty interest (ORRI) is not the same as a mineral interest. An ORRI is lease-dependent and expires when the underlying lease expires. A mineral interest is perpetual. Confusing the two is one of the most common due diligence mistakes in Fort Worth Basin acquisitions.

• The Texas Comptroller imposes severance tax at 4.6% on oil and 7.5% on gas; qualifying owners may deduct percentage depletion at 15% of gross income under IRS Publication 535; reserve classifications follow SEC Regulation S-X Rule 4-10; under Texas Estates Code, mineral interests held individually pass through probate at death — unestablished heirship is the most common title defect in Comanche and Eastland County acquisitions

Frequently Asked Questions

What is the difference between mineral rights and surface rights in Texas? In Texas, a single tract of land can be divided into two separate estates: the surface estate (everything above ground, including the right to use the land) and the mineral estate (oil, gas, coal, sulphur, and other subsurface resources). These two estates can be owned by different parties. When they are, the property is called a split estate. The mineral estate is the dominant estate under Texas law, meaning the mineral owner's right to develop the subsurface generally takes precedence over the surface owner's preferences, subject to the accommodation doctrine.

What is a split estate and how common is it in Texas? A split estate is a tract of land where the mineral estate and the surface estate are owned by different parties. Split estates are extremely common in Texas due to decades of mineral reservations in ranch and farm deeds. In counties with long oil and gas histories — Comanche, Eastland, Palo Pinto, Stephens, and others — a large percentage of land has severed minerals. Buyers of surface land in Texas should always conduct a mineral title review to determine whether the minerals are included in the purchase.

Can a surface owner prevent an operator from drilling on their land? Generally not. Under the dominant estate doctrine, the mineral owner's right to develop the minerals takes precedence over the surface owner's preferences. An operator acting under a valid oil and gas lease has the right to use as much of the surface as is reasonably necessary for mineral development, without the surface owner's consent. The accommodation doctrine requires the operator to consider alternative methods of development that would not substantially interfere with an established surface use — but it does not give the surface owner a veto right over drilling.

Do mineral rights expire if no drilling occurs? A mineral interest in Texas does not expire simply because no development has occurred. An unleased mineral interest remains valid indefinitely. An oil and gas lease, however, does have a defined primary term — typically one to five years — after which it expires if production has not been established. The mineral interest itself is perpetual; the lease is not.

What is the difference between a mineral interest and an overriding royalty interest (ORRI)? A mineral interest is a perpetual ownership interest in the subsurface resources beneath a tract of land. It survives lease expiration and can be conveyed independently of any lease. An overriding royalty interest (ORRI) is carved out of the working interest under a specific oil and gas lease and entitles the holder to a share of production revenue free of costs — but only for as long as that lease remains in effect. When the lease expires, the ORRI expires with it. Buyers should confirm whether they are acquiring a mineral interest or an ORRI, as the two have fundamentally different values and risk profiles.

How do I find out if the minerals have been severed from the surface on a Texas property? The only reliable method is to examine the full chain of title in the county deed records where the property is located. A title examiner reviews every deed in the chain — going back to the original patent from the State of Texas — to identify any reservation or conveyance of the mineral estate. This examination will reveal whether the minerals have been severed, who currently owns them, whether the mineral estate has been fractionally divided, and whether there is an active oil and gas lease. For mineral interest acquisitions, a title search is not optional — it is the foundation of any responsible purchase.
