How to Find Out If You Own Mineral Rights

Many landowners assume they own everything beneath their property. In many states, however, the mineral rights can be — and frequently are — separated from the surface. If you have ever wondered whether you actually own the minerals under your land, this guide walks you through how to find out.

Understanding the Mineral-Surface Split

In the United States, mineral rights are a separate form of real property that can be bought, sold, gifted, or inherited independently from the surface estate. This separation — called a mineral severance — can happen through a deed, will, or court order, and it can date back generations.

Once severed, the mineral estate remains separate in perpetuity unless reunited through a later transaction. A surface owner who does not also own the minerals has no right to oil, gas, coal, or other subsurface resources — and no right to royalty income from production.

Step 1: Review Your Deed

The first place to look is the deed by which you acquired the property (the warranty deed, grant deed, or quitclaim deed recorded when you bought or inherited the land).

Look for language like:

• "together with all mineral rights" — this suggests the minerals were included in your conveyance

• "subject to all reservations of record" — this means an earlier owner may have reserved the minerals

• "less and except all oil, gas, and other minerals" — this means the minerals were explicitly excluded from your purchase

• "reserving unto grantor a 1/2 mineral interest" — this means the seller kept half the minerals

If your deed is silent on minerals — meaning it does not specifically mention them at all — the default rule in most states is that the minerals transfer with the surface. But you still need to check whether a prior owner severed them in an earlier deed.

Step 2: Search the County Records

Mineral ownership is established through the chain of title — the sequence of recorded documents transferring the property from owner to owner. You can research this at the county clerk's or recorder's office in the county where the land is located.

What you are looking for:

• Mineral deeds — documents conveying mineral interests separately from the surface

• Mineral reservations — clauses in surface deeds where the seller kept the minerals

• Oil and gas leases — recorded leases between the mineral owner and an operator, which identify who the lessor (mineral owner) is

• Probate records — if the property passed through an estate, the probate file may clarify who inherited the minerals

In many states, these records are indexed by grantor (seller) and grantee (buyer). You trace the chain backward from your deed to the original patent from the state or federal government, looking for any transaction where the minerals were separated.

Step 3: Check for Active Leases or Production

If there is active oil and gas production on or near your property, there are additional clues:

• Division orders: If you are receiving royalty checks, the operator has already determined you are the mineral owner (or one of them). Your division order will show your decimal interest.

• State regulatory databases: Every producing state maintains a public database of well permits, production reports, and operator information. In Colorado, this is the ECMC (formerly COGCC); in Texas, the Railroad Commission; in Oklahoma, the OCC. You can search by legal description or location to see if any wells are producing on your land.

• Contact the operator: If you know which company operates the wells, call their division order or land department and ask about the mineral ownership for your tract.

Step 4: Hire a Title Professional

If the records are complex or you cannot determine ownership yourself, consider hiring a landman or a title attorney who specializes in oil and gas. These professionals trace mineral titles for a living and can produce a title opinion — a legal document that definitively states who owns the minerals.

Title work typically costs between $300 and $2,000 depending on the complexity and age of the chain of title. In some cases, mineral buyers like Sagebrush MG will perform title work at their own expense as part of the acquisition process.

Common Situations Where Minerals Were Severed

• Homestead-era reservations: Federal and state land patents in the early 1900s sometimes reserved minerals to the government

• Railroad grants: Large land grants to railroads in the 19th century often came with mineral reservations

• Family divisions: When a landowner died and left the surface to one heir and the minerals to another

• Speculative purchases: During oil booms, speculators bought mineral rights from surface owners across producing regions

• Institutional ownership: Banks, trusts, and mineral aggregation companies have purchased mineral interests over decades

What to Do Once You Know

If you confirm that you own mineral rights, you have several options:

• Hold and collect royalties if the minerals are currently leased and producing

• Negotiate a new lease if the minerals are open (unleased) and you want to retain ownership while receiving lease bonus and royalty payments

• Sell your mineral interest for a lump sum. A direct buyer like Sagebrush MG can provide a free, no-obligation valuation based on engineering analysis and comparable transactions

If you discover that you do not own the minerals, your options are more limited — but understanding your ownership status protects you from entering into lease agreements you have no authority to sign.

The Bottom Line

Determining mineral ownership requires careful document research, and the answer is not always straightforward. Values depend on many factors and can go up or down based on production, commodity prices, and operator activity. If you suspect you own mineral rights but are not sure, a title search is the only reliable way to confirm. We recommend consulting a qualified landman or oil and gas attorney for a definitive answer.
