Pull the current deed for reservation language, then trace prior deeds backward through the county recorder’s grantor-grantee or tract index looking for where “oil, gas, and other minerals” were excepted or reserved. Cross-check the parcel’s location against the state oil and gas commission’s well and lease database, and ask your title company to confirm the mineral chain before you close.
What does it mean if a parcel’s mineral rights have been severed from the surface?
A severed mineral estate means a prior owner split the oil, gas, and other minerals from the surface, so a warranty deed that conveys “the land” no longer conveys everything beneath it. Once severed, the mineral estate becomes its own legal interest that can be sold, leased, or inherited independently of the surface, and it does not automatically come back together just because the same person later buys the surface.
This matters because, in most states, the mineral estate is treated as the dominant estate. According to the Texas A&M Real Estate Research Center, oil companies and mineral owners have an implied right to use “as much of the physical surface and substances belonging to the surface owner as is reasonably necessary” to explore and produce, typically without paying the surface owner for that use. A related body of case law, including the accommodation doctrine, can require a mineral operator to use a reasonable alternative method if its planned operations would completely block an existing surface use and a reasonable alternative exists, but the surface owner carries the burden of proving that, according to the same Texas A&M Real Estate Research Center source. None of this requires a well to already exist: the implied right to use the surface exists, as Producers Edge Law explains, because a mineral grant would otherwise be worthless without surface access. It only requires the right to have been reserved at some point in the chain of title, which is exactly why a buyer needs to check before closing rather than after a landman shows up.
How do you find severed mineral language in the deed you’re buying?
Start by reading the legal description and exceptions section of the deed you are actually being asked to sign, not just the listing description, and look for phrases like “save and except,” “reserving unto grantor,” or “excepting all oil, gas and other minerals.” A severance is created by specific language in a recorded instrument, so if that language is absent from the deed in front of you, it does not mean minerals are intact; it only means this particular deed does not address them, and the severance could have happened earlier in the chain.
Reservation language typically appears in one of a few forms: a full reservation of “all oil, gas and other minerals,” a fractional reservation such as “an undivided one-half interest,” or a reference to a separately recorded mineral deed. Each of these has different consequences for what you actually own if you close. If the deed is silent and you cannot find a severance anywhere in the prior chain, that is meaningful evidence the mineral estate is still intact, but it is not proof; a full search of the recorded chain is the only way to be reasonably sure.
Pay attention to how broadly the reservation is written, too. “Oil and gas” is narrower than “oil, gas, and other minerals,” and some older deeds use even broader catch-all language covering “all minerals of every kind and character.” Whether that broad language also captures things like sand, gravel, or caliche has been litigated differently state to state and even case to case, so a reservation you assume is limited to oil and gas may, on a closer read, be broader than it first appears. This is a detail worth flagging to your title company or attorney rather than interpreting on your own.
How do you trace the mineral chain of title at the county recorder’s office?
County recorders and clerks index recorded deeds in a grantor-grantee index (sometimes called a grantor-grantee register), organized alphabetically by the parties’ names, and some counties also maintain a tract index organized by legal description that lets you pull everything ever filed against a specific parcel. Where a tract index exists for your parcel’s county, use it; where it doesn’t, you work the name indexes one link in the chain at a time.
The practical method is to work backward in time:
| Step | What you do | What you’re looking for |
|---|---|---|
| 1 | Start with the current owner (grantee) in the grantee index | The deed by which the current owner acquired the property |
| 2 | Read that deed’s legal description and exceptions | Any “save and except” or reservation of oil, gas, and minerals |
| 3 | Find the grantor of that deed, then search for them as a grantee earlier in time | The deed by which they acquired it, continuing the chain backward |
| 4 | Repeat for each prior owner, ideally back to the original government patent or earliest available record | Every point where minerals may have been reserved, conveyed, or leased |
| 5 | Note any separately recorded mineral deeds, royalty deeds, or oil and gas leases affecting the tract | Fractional interests, active leases, or a mineral owner different from the surface owner |
Each hop in the chain can introduce a reservation, and once minerals are severed at any point, they generally stay severed unless a later deed explicitly reunites the two estates. In counties with generations of inherited fractional interests, a single tract can end up with a dozen or more mineral co-owners, which is one reason title companies and professional landmen exist. If the chain is long, spans multiple counties, or the handwriting on 1940s-era deeds is hard to read, that is a reasonable point to hand the search to a professional rather than rely on a do-it-yourself read of the index.
How do you check a state oil and gas commission’s database for wells and leases?
A deed search tells you who owns the minerals; a state oil and gas commission’s records tell you whether anyone has actually done anything with them, such as permitting, drilling, or producing a well on or near the parcel. In Texas, the Railroad Commission of Texas makes well records searchable through its Oil and Gas Imaged Records Query and its Public GIS Viewer, with online records covering 1964 to the present and older files available on microfilm back into the 1920s. In Oklahoma, the Oklahoma Corporation Commission offers a Well Data Finder tool that lets you search by well name, API number, county, legal location, or operator, along with an imaged documents directory for filings made before its 2022 shift to electronic case filing.
Most oil- and gas-producing states run an equivalent conservation commission or agency with a similar public search tool, though the interface, coverage dates, and how far back scanned images go all vary by state. When you search, look up the parcel by legal location (survey, section, township and range, or equivalent) rather than by owner name, since a well permitted decades ago may be tied to a company or landowner name that no longer matches anything on the current deed. A hit doesn’t necessarily mean there’s an active well on your specific tract; it may reflect a well on a neighboring parcel that is nonetheless part of a pooled or unitized drilling area that includes yours.
If you’re buying in Texas and the search turns up an active lease or permit near the parcel, that is worth factoring into your decision alongside any local market context; see our Texas land page for state-specific background if you’re weighing next steps on a property there.
What does an ALTA 35 mineral endorsement actually cover?
The ALTA 35 series does not give you the minerals back or stop a mineral owner from drilling; it insures against a narrower and more specific risk. According to Williams Mullen, the base ALTA 35-06 endorsement covers the enforced removal or alteration of a building resulting from the future exercise of a right to use the surface for mineral extraction, while variants such as 35.1-06 extend that protection to improvements more broadly, and 35.3-06 extends it to both existing and future improvements on land under development. These endorsements are used more often in states where mining or drilling activity is common, and underwriters typically require plans and specifications for any structure before issuing the coverage.
In practice, this endorsement matters most when you already know minerals are severed and you plan to build. It compensates you if a mineral operator’s lawful surface use later forces you to move or alter a structure; it does not address royalty income, does not restore surface control, and does not substitute for actually knowing whether the parcel’s minerals were severed in the first place. Ask your title company directly whether an ALTA 35 endorsement is available for your transaction and what it costs to add, since availability and underwriting requirements differ by state and by insurer.
Underwriters generally will not issue ALTA 35 coverage blind. According to Williams Mullen, these endorsements require submitting plans and specifications for the relevant building or improvement, and they are used more often in states where mining or oil and gas activity is common than in states where it isn’t. If you’re buying raw acreage with no immediate building plans, the endorsement may not be relevant yet; if you’re buying to build a home, shop, or other structure on a parcel with a known severed mineral estate, it’s worth raising with your title company at the same time you order title work, not after the loan or contract is already locked in.
What should you do if the search turns up a severed mineral estate?
Finding a severed mineral estate is not automatically a reason to walk away, but it is a reason to adjust your due diligence and your offer. Confirm exactly what was reserved (all minerals or a fraction, oil and gas only or “other minerals” too), whether any lease is currently active, and whether the reservation includes surface-use language that limits where the mineral owner can operate. A purchase-and-sale agreement should give you time to complete this search, similar to the other title and boundary issues covered in 7 Red Flags in a Vacant Land Purchase Agreement; mineral status belongs on that same due-diligence checklist, not as an afterthought discovered at the title company days before closing.
Once you know what you’re dealing with, your options typically include negotiating the price to reflect the risk, asking the title company about an ALTA 35 endorsement if you plan to build, or simply proceeding with clear eyes if the severed interest is old, fractional, and shows no history of activity. For background on the broader due diligence sequence before you commit to a parcel, see our buying land guide, and for how a severed mineral estate is defined as a title matter, see the glossary.
If you’re on the other side of this, holding a parcel with a severed or clouded mineral history and considering an exit instead of a purchase, AMM Land Sales makes cash offers on vacant land nationwide, including parcels with unresolved mineral records, and settles closing through a licensed title company rather than asking a seller to untangle the mineral chain themselves.
