Owning the surface of a piece of land does not automatically mean you own what lies beneath it. To find out if you own the mineral rights to your property, start with the deed and title insurance policy from your purchase, rule out a federal mineral reservation on the original land patent, and then trace the chain of title at the county recorder’s office back through every prior owner. In much of the United States, minerals can be legally separated from the surface and sold or reserved independently, creating a split estate, and a single severance decades ago is enough to mean the minerals are no longer yours.
Start With Your Deed and Title Policy
The fastest evidence is already in your files. Pull out your deed and read it word for word, watching for any mention of “minerals,” “oil and gas,” “subsurface rights,” or “mineral rights.” You are looking for two things: language that explicitly includes minerals in the sale, or language that carves them out. A previous owner who wanted to keep the minerals might have written something like “reserving all oil, gas, and other minerals” or “excepting and reserving unto the grantor the mineral estate.”
If your deed says nothing about minerals at all, that is actually a good sign. In most situations, a deed that conveys property without mentioning minerals transfers everything, including the subsurface. But silence in your deed only tells you what happened in your transaction; it does not tell you what happened before it.
Next, open your title insurance policy to Schedule B, the section listing exceptions to coverage. If a prior owner severed the minerals, the title company should have flagged it here. You might see language like “all oil, gas, and other minerals of every kind and character are expressly excluded from coverage,” or a reference to a specific recorded document that granted or reserved a mineral interest. The policy may also note an exception for “the right to use the surface estate for ingress and egress incident to the ownership of the mineral estate,” which suggests someone else holds the minerals and has certain access rights. If your policy insures only the “surface estate” rather than “fee simple,” that is another clear indicator.
Closing disclosures and settlement statements can contain mineral-related notes too, though they are less detailed. Treat all of this as a first pass. It will either confirm you own the minerals, raise a red flag, or leave enough ambiguity that you need to move into public records.
What You Need Before Searching Public Records
Before you head to the courthouse or open an online records portal, gather two things.
The first is your property’s legal description. This is not the street address. It is the formal description recorded in your deed, and it usually includes a section, township, and range in states that use the rectangular survey system, or a subdivision name with lot and block numbers. You will find it on your deed or your property tax statement.
The second is the names on your deed. The person who sold you the property is the grantor; you are the grantee. County records are indexed by those names, so tracing ownership means moving grantor to grantor, backward in time.
Check Whether the Federal Government Kept the Minerals
Before you spend hours tracing private transfers, rule out a common scenario that trips up landowners across the western United States. Under the Stock-Raising Homestead Act, the federal government reserved all coal and other minerals on millions of acres of homesteaded land. The law states that patents issued under its provisions “shall be subject to and contain a reservation to the United States of all the coal and other minerals in the lands so entered and patented, together with the right to prospect for, mine, and remove the same.”1Office of the Law Revision Counsel. 43 USC Subchapter X – Stock-Raising Homestead If the original patent for your land came through this program, the federal government still owns those minerals regardless of how many times the surface has changed hands.
You can check this through the Bureau of Land Management’s General Land Office Records site, which holds digital copies of original land patents going back to the 1800s. Search by legal description or location, pull up the patent, and read it for any reservation language. The BLM also runs the Mineral and Land Records System, an online platform where you can research federal mineral and land records, search by legal land description, and review reports on areas of interest.2Bureau of Land Management. Mineral and Land Records System (MLRS)
If your land traces back to a federal patent with reserved minerals, the private chain of title will not tell you anything about mineral ownership because those rights never entered private hands. This is the single most common dead end for landowners in states where federal homestead programs were active, and checking it first can save you significant time and money.
Running the Chain of Title at the County Recorder
If the federal government did not retain the minerals, the next step is tracing the private ownership history. Visit the county recorder’s or clerk’s office where the property sits. Many counties now offer online access to recorded documents, though older records are often available only in person. Either way, the process is the same.
You are building a chain of title: the complete sequence of ownership transfers for your parcel, from the present day back as far as the records go. Start with the grantor on your deed, the person who sold to you. Search the grantor-grantee index to find the document where that person acquired the land. Then take the grantor from that earlier deed and repeat. Each link is one transaction, and you work backward, owner by owner, decade by decade.
At every step, read the full text of each deed for language that splits the minerals from the surface. The severance could have happened 20 years ago or 120 years ago. It only takes one. If a seller in 1940 kept the mineral rights when conveying the surface, every buyer after that purchased only the surface, even if none of their later deeds mention minerals. This is where landowners get tripped up. The absence of mineral language in your own deed does not mean you own the minerals if someone earlier in the chain already separated them.
How to Spot a Mineral Severance in Old Deeds
Knowing what severance language looks like keeps you from reading right past the critical clause. Two mechanisms come up most often, and they work in opposite directions.
A mineral deed is a standalone document where the surface owner sells or transfers the mineral rights to someone else while keeping the surface. The deed describes the minerals being conveyed and identifies the new mineral owner.
A reservation clause appears inside a regular property deed. The seller transfers the surface but writes in a clause keeping the minerals. You might see phrases like “reserving unto the grantor all oil, gas, and other minerals in and under the above-described land” or “this conveyance is of the surface estate only.” Some older deeds use “excepting and reserving” to do the same work.3USDA Forest Service. FSM 2830 – Minerals and Geology
Watch for partial severances too. A deed might reserve “one-half of all minerals” or convey only specific resources like “all oil and gas” while leaving other minerals with the surface. The language matters, and vague or poorly drafted clauses from decades past are one of the main reasons mineral ownership disputes end up in court.
What You Might Actually Own
As you trace the chain, you may discover that what a prior deed conveyed or reserved is not a full mineral interest but something narrower. The distinction affects what your rights are worth.
A full mineral interest is ownership of the subsurface resources with executive rights: the ability to sign leases, negotiate bonus payments and royalty rates, and decide whether and when development happens. The holder can receive lease bonuses, annual rental payments, and royalties once production begins.
A royalty interest is more limited. It entitles the holder to a share of production revenue, with no say in leasing decisions and no executive rights. There is no obligation to cover drilling or extraction costs, but there is also no ability to initiate or block development.
A non-executive mineral interest sits between the two. The holder owns the minerals themselves but someone else holds leasing authority. Bonus payments and royalties still flow to the mineral owner, but they cannot sign a lease alone.
Fractional Interests
Mineral rights also splinter among heirs. When a mineral owner dies without a will or leaves the rights to multiple children, those children each inherit an undivided fractional interest. Three siblings might each own an undivided one-third. When those siblings die, their shares divide again. After three or four generations, a single mineral tract can have dozens or even hundreds of fractional owners.
Fractional interests also create confusion in old deeds. A clause granting “one-fourth of one-eighth of all royalty” could mean different things depending on when it was written. Before the 1970s, most leases carried a standard one-eighth royalty, so “one-fourth of royalty” was understood to mean one-fourth of one-eighth, or one thirty-second. Modern royalty rates vary widely, which makes older fractional language ambiguous. If your search turns up a fractional interest, pay close attention to the exact fraction and how it was created.
When to Hire a Landman or Mineral Title Attorney
At some point in this process, most people hit a wall. The chain might stretch back 150 years through faded handwriting and obscure legal terms. A deed might contain ambiguous language whose meaning depends on state law. Or you might simply want legal certainty before signing a lease worth real money.
This is where a mineral title attorney or a professional landman earns the fee. A landman specializes in researching mineral ownership and can conduct a thorough search of county and federal records. An attorney experienced in mineral law goes further, producing a formal title opinion: a written legal document that analyzes the chain of title and states who owns what. Title opinions are standard practice in the oil and gas industry, and any reputable company will require one before signing a lease or paying royalties.
Expect to pay. Mineral title examinations typically run several hundred dollars per hour, and the total depends on how far back the records go and how complicated the ownership history is. A straightforward chain with few transfers might cost a few hundred dollars. A tract with multiple severances, fractional interests, and missing heirs can run into the thousands. The investment is almost always worth it. A title opinion protects you from signing a lease you do not have the right to sign, and it protects a lessee from paying someone who does not actually own the minerals.
If Your Search Shows Someone Else Owns the Minerals
If your search confirms that someone else holds the minerals under your land, you are not powerless as a surface owner, but the mineral estate is dominant, meaning the mineral owner has the right to use the surface to reach the resources. Courts in many states have adopted some version of the accommodation doctrine, which requires mineral developers to use reasonable alternative methods when their operations would destroy an existing surface use, provided those alternatives are established industry practices.
Federal law adds protection on land originally patented under the Stock-Raising Homestead Act. On those lands, no one other than the surface owner may explore for or locate mining claims without first filing a notice and notifying the surface owner. Actual mining operations require either the surface owner’s written consent or authorization from the Secretary of the Interior. If the Secretary authorizes the work, the operator must post a bond covering compensation for permanent crop and improvement damage, lost grazing income, and full reclamation of the surface.1Office of the Law Revision Counsel. 43 USC Subchapter X – Stock-Raising Homestead Outside that federal framework, surface owners in active drilling areas should consider negotiating a surface use agreement before operations begin, because leverage disappears once a rig is on location.
