Do I Own the Mineral Rights to My Property?

Owning the ground does not automatically mean owning what is under it — here is how to find out, step by step

This is the single most common question property owners ask about minerals, and it usually arrives with a trigger attached: a letter from a landman, a neighbor's new well, a survey crew on the county road, or an estate that has to be settled. The good news is that the answer is knowable. Mineral ownership in the United States is a matter of public record, and a patient owner working from a deed and a county index can usually get to a defensible answer without hiring anyone. This page shows the sequence.

Why Surface Ownership Is Not Mineral Ownership

The concept that trips people up is simple once you see it. American property law treats the surface estate — the ground you can stand on, farm, fence, and build on — and the mineral estate — the oil, gas, and other minerals beneath it — as two distinct pieces of real property. They start out in the same hands. They do not have to stay there.

Severance is the moment they come apart, and it happens in one of two ways. Either the owner sold the minerals away with a mineral deed and kept the land, or — far more commonly — the owner sold the land and reserved the minerals in the deed. That second pattern is how most long-standing family mineral ownership in America was created: a farm changed hands two or three generations ago, one sentence in the deed held the minerals back, and the family has owned something under land it has not visited since.

Once severed, the two estates never rejoin on their own. They are separately deeded, separately taxed, separately probated, and separately leased, and a severance made in 1931 binds every buyer of the surface who came afterward, whether or not any later deed mentions it. That is why "my deed doesn't say anything about minerals" is not an answer. For the full picture of what the mineral estate actually contains once you find it — the executive right to lease, bonus, delay rentals, royalty, and the right to develop — see anatomy of a mineral estate.

Two more corrections worth making before you start researching:

• Your title policy does not settle it. Owner's title insurance ordinarily lists prior mineral reservations as an exception on Schedule B and expressly does not insure mineral title. An exception in your policy is actually a useful clue — it often names the severing instrument by book and page.
• Paying taxes on the land does not settle it either. Severed minerals are usually assessed separately and, in many states, only once they produce. A surface owner can pay property taxes faithfully for forty years on a tract whose minerals belong to someone else.

How to Find Out Whether You Own Your Mineral Rights: 5 Steps

Run these in order. Each step either answers the question or hands you the specific document you need for the next one.

Step 1: Start with your deed

Find the deed that put the property in your name and read all of it, not just the property description. Two places carry the answer:

• The granting clause — what the grantor actually conveyed. Language like "all of Grantor's right, title and interest" behaves differently from a conveyance of a specific described estate.
• Everything after "reserving," "excepting," "save and except," or "less and except." This is where minerals disappear. A clause reading "save and except an undivided one-half of all oil, gas and other minerals heretofore reserved by predecessors in title" is telling you plainly that half the minerals — at least — are not yours.

Watch for the difference between a reservation (the grantor is keeping something for themselves) and an exception (the grantor is acknowledging that someone else already owns it). The second kind is a breadcrumb: it means the severance happened earlier in the chain, and the deed may even cite the earlier instrument by book and page.

Then pull your title insurance policy and closing file. Schedule B exceptions frequently spell out the mineral reservation and identify the recorded document that created it, which can save you hours in the index. And note the legal description exactly as written — county, survey and abstract number, section, block, or lot and block. Every subsequent search runs off that description.

Important: silence is not ownership. If your deed says nothing about minerals, you still do not know. Go to Step 2.

Step 2: Search the county clerk or recorder's land records

Land records live in the county where the land sits — not where you live, and not where you closed. The office goes by different names depending on the state: the county clerk in Texas, Oklahoma, New Mexico, Wyoming, and West Virginia; the county recorder in North Dakota and Ohio; the register of deeds in Kansas; the clerk and recorder in Montana; the recorder of deeds in Pennsylvania. Valor's county clerk and recorder directory gives you the office, address, phone, hours, and online-records status county by county, including complete coverage of Texas counties and Oklahoma counties — the two states where owner questions concentrate.

County records are indexed by names, not by maps. There are two indexes, and you will use both:

• The grantor index lists everyone who conveyed something out — sellers, lessors, people who reserved minerals. Look up a prior owner here to find everything they gave away.
• The grantee index lists everyone who received something. Look up a prior owner here to find how they acquired the property in the first place.

The method: take the person you bought from, find them as grantee to see who they bought from, then look up that person as grantee, and keep stepping backward. Then walk forward through the grantor index for each name, reading every instrument they filed — deeds, mineral deeds, oil and gas leases, releases, easements. Write down the book and page number of everything; those citations are how the whole system cross-references. Some counties and most commercial title plants also keep a tract index organized by legal description, which pulls everything ever filed against a specific tract in one shot — use it wherever it exists.

Many counties now publish a searchable online index, but coverage usually stops at some cutoff year and older instruments still require an in-person visit, a phone call, or a mail request. A full walkthrough of index mechanics, what to photograph, and how to keep your notes is in Valor's courthouse mineral research guide.

Step 3: Trace the severance history

Somewhere in that chain, if the minerals are gone, there is one instrument that took them out. Finding it is the whole point of Step 2, because that document defines what every owner downstream of it holds — including you.

When you find it, read it literally and answer five questions:

1. Which way did it go? A mineral deed conveyed the minerals out to a buyer. A reservation in a surface deed kept the minerals back with the seller. Either way the surface and the minerals parted company, but the identity of the current mineral owner runs in opposite directions.
2. How much moved? "All" is uncommon. Fractions — one-half, one-fourth, one-sixteenth — are the norm, and a partial severance leaves the parties as co-owners of an undivided interest in the whole mineral estate rather than owners of mapped-out pieces of it.
3. Was it limited? Severances are sometimes restricted by depth ("all minerals below the base of the deepest producing formation") or by substance ("coal only," "oil and gas only"). A limited severance can leave you owning more than you think.
4. Was it permanent or a term interest? Some reservations run for a fixed number of years "and so long thereafter as production continues." A term interest that expired without production reverts — meaning the minerals may have come back to the surface owner without anyone filing a thing.
5. Was it the full mineral estate or only the royalty? A reservation of a royalty interest alone leaves the mineral estate — including the right to lease — with the mineral owner. These read similarly and mean very different things; the distinction is covered in NPRI vs. royalty interest.

Once you have the severing instrument, work forward from it in the grantor index under the name of whoever kept the minerals. That forward trace is what tells you who owns them today — and it very often runs straight into Step 4.

Step 4: Check probate and heirship if the interest passed by inheritance

Here is where most owner searches stall, and the reason is structural: severed minerals usually pass by death, not by sale, and death does not generate a deed. The last name recorded as mineral owner in the land records is frequently someone who died in 1974. Nothing is wrong with the record — the interest simply moved by will or by intestate succession, and the paper that documents it lives somewhere else.

So when the trail goes cold on a name, look for:

• A probated will or an order of distribution from the estate, filed in the probate or district court of the county where the person lived when they died.
• An affidavit of heirship — a sworn statement of family history recorded in the land records, commonly used where no probate was opened. It is not as strong as a probate order, but it is what much of the industry runs on.
• A trust instrument or a deed from a trustee, if the family put the minerals into a trust.
• An ancillary filing. If the decedent lived in a different state from the minerals, the estate documents often have to be recorded again in the mineral county before they appear in that county's chain. Plenty of interests look "unresolved" purely because that second filing never happened.

Expect the fractions to shrink. An interest that started as one-half of the minerals under 320 acres, divided among four children and then among their children, becomes a set of small undivided interests spread across cousins in several states. That is normal, and it is why converting your share to net mineral acres is a better description of what you own than a bare fraction. If this is your situation, Valor's guide to inherited mineral rights covers the whole sequence from confirming ownership through getting into pay. Where the family record is genuinely gone, some states also have dormant mineral statutes that can affect long-abandoned interests.

Step 5: Get a professional title opinion or landman when the stakes justify it

Owner-level research answers the question most of the time. It stops being enough at a predictable set of points:

• The chain runs through several counties or several states.
• The deed wording is genuinely ambiguous — a fixed-versus-floating fraction, a depth limitation with no defined datum, a conveyance that contradicts a prior reservation.
• An estate was never probated, or the heirs disagree.
• There are defects in title — gaps in the chain, unreleased old leases, a missing signature, a name that changed.
• Someone is asking you to sign something: an oil and gas lease, a division order, a stipulation of interest.

Two different professionals do two different jobs here. A landman assembles the runsheet — an ordered list of every instrument in the chain, with book, page, and effect. An oil and gas attorney licensed in that state reviews the runsheet and issues a title opinion, which states who owns what and lists the curative work needed to reach clear title. That opinion is the document operators actually rely on when deciding whom to pay.

One thing worth saying plainly: a division order and a check stub are not title. They tell you what an operator currently believes about your interest. Operators are wrong often enough — wrong decimals, wrong owner, stale addresses — that the belief is worth auditing against the record rather than accepting. See division order management for how to check one before signing it.

Where the Answer Lives: A Quick Reference

General industry usage. Office names, recording practice, and probate procedure vary by state; the wording of your own instruments controls in every case.

Because those rules — severance history, recording offices, dormant-mineral and probate procedure — differ from state to state, the fastest confirmation usually starts with your own state. See the mineral rights guide for Arkansas, Colorado, Illinois, Kansas, Louisiana, Montana, New Mexico, North Dakota, Ohio, Oklahoma, Pennsylvania, Texas, Utah, West Virginia, Wyoming.

You Found Out You Own Them. Now What?

Confirming ownership is the beginning of the work, not the end of it. A mineral interest is an operating asset — it generates documents, deadlines, and payments, and it degrades quietly when nobody is watching it. A practical order of operations:

1. Build the file. The severing instrument, every deed and probate filing that carried the interest to you, the legal description, and your fraction. Convert the fraction to net mineral acres so you can talk about size in the units the industry uses.
2. Find out whether it is leased or producing. An unreleased old lease changes what you can do; active production means there may be money owed. Start with unleased minerals or organizing your royalties depending on which you find. If it is producing, the royalty calculator gives a rough sense of the income — enter your net mineral acres, royalty rate, and a price to estimate a monthly figure.
3. Make sure operators can find you. Wrong names, old addresses, and missing tax identification are the top reasons owners never get paid. If revenue has been accruing without you, check unclaimed mineral and royalty funds and what to do when no division order arrives.
4. Verify before you sign anything. A lease offer and a division order both deserve review against your own record first.
5. Decide how it gets administered. Self-manage, or hand it to a professional. Either is defensible; drift is not.
