When someone dies, their oil royalties become part of their estate and pass to heirs the same way other property does: through a will, a trust, a transfer-on-death deed, joint ownership, or, if none of those are in place, through state intestacy law. The mineral interest itself transfers to whoever inherits it, and the monthly royalty checks start flowing to that person once the operating company confirms the new owner. Most estates owe no federal estate tax because the 2026 exemption is $15 million per individual, but every heir who collects royalty income owes ordinary income tax on it going forward.1Internal Revenue Service.

Who Inherits the Royalties
If there’s a will, it controls. The executor named in the will moves the mineral interests through probate and distributes them to the beneficiaries the deceased chose. If there’s no will, the state’s intestacy statute decides, usually starting with a surviving spouse and then children. Heirs don’t get to pick; the default rules apply automatically.
A revocable living trust changes the picture entirely. When mineral interests were transferred into a trust during the owner’s lifetime, the successor trustee takes over at death and the operating company can keep sending payments into the trust account without a court proceeding, because the trust is the legal owner.
Funding the trust is the step people miss. Creating a trust document doesn’t move anything; the mineral interest has to be deeded from your personal name into the trust’s name, with the legal description of the minerals and, if there’s an active lease, an assignment of the lease rights. A trust that was never funded sends the minerals through probate anyway.
Ways to Skip Probate
Transfer-on-Death Deeds
Roughly 34 states allow transfer-on-death deeds for real property, including mineral rights. You sign a deed naming a beneficiary and record it in the county where the minerals sit. You keep full ownership and control while you’re alive and can revoke the deed at any time. After death, the beneficiary records an affidavit with a death certificate and the interest passes without court involvement.
Joint Tenancy With Right of Survivorship
Minerals held in joint tenancy pass automatically to the surviving owner. The survivor records the death certificate with the county and notifies the operator. This is clean for two owners and gets messier with more. It also locks in the result: the survivor inherits regardless of what any will says.
How Probate Transfers Work
When minerals do go through probate, the executor includes them in the estate inventory and manages any active leases during the case, which means collecting royalty checks, tracking production, and dealing with the operating company.
Valuing oil royalties for the estate is harder than appraising a house. The number depends on current commodity prices, the well’s production history, remaining reserves, lease terms, and future drilling potential, and producing wells usually require an appraiser with oil and gas experience. The valuation matters for estate tax and for each heir’s stepped-up basis.
Once the court issues its final distribution order, the actual transfer happens at the county recorder’s office in the county where the minerals are located. The typical filing is a mineral deed or assignment along with a certified copy of the probate order. Where there’s no will and no formal probate, an affidavit of heirship, a sworn statement identifying the deceased’s heirs, can stand in as the chain-of-title document and gets recorded the same way.
Notifying the Operating Company
Recording in the county establishes legal ownership, but checks don’t start again until the operator updates its records. Heirs should send the operator a certified copy of the death certificate, the recorded deed or court order, and a W-9 for each new owner. The operator reviews the paperwork, confirms the chain of title, and updates its pay records.
Most operators then require each heir to sign a new division order certifying their decimal interest in production. Until that’s signed, the operator has no confirmation of how much to pay or to whom, and payments stay on hold.
If the Minerals Are in Another State
Mineral rights are governed by the law of the state where they’re located, so owning minerals outside your home state usually means a second probate case, called ancillary probate, in that state. Some states streamline this by accepting the home-state executor’s authorization along with a copy of the will; others require a full separate proceeding. A funded trust or a transfer-on-death deed avoids ancillary probate entirely, which is one of the strongest reasons to use one if you own out-of-state minerals.
What Happens to the Checks in the Meantime
Operating companies stop paying a deceased owner as soon as they learn of the death. The money doesn’t disappear; it accumulates in a suspense account until a new owner establishes clear title. The hold can last months or years if the estate is contested, the will isn’t probated promptly, or documentation is incomplete.
If suspended payments sit untouched long enough, the operator has to turn them over to the state as unclaimed property. The dormancy period varies by state and commonly runs three to five years of inactivity. Heirs can still claim escheated funds through the state’s unclaimed property office, but it’s another layer of bureaucracy. Moving quickly on probate and title documentation is the best way to avoid it.
Estate Tax
Royalties are included in the deceased’s taxable estate at fair market value on the date of death. For 2026, the federal estate tax exemption is $15 million per individual under the One, Big, Beautiful Bill Act signed on August 5, 2025. Estates below that owe no federal estate tax; estates above face a top marginal rate of 40% on the excess.1Internal Revenue Service.

Married couples can effectively double the exemption to $30 million through portability, but it isn’t automatic. The surviving spouse’s executor has to file Form 706 for the first spouse’s estate within the deadline, including extensions, even if no tax is owed. Miss the filing and the unused exemption is forfeited permanently.3Office of the Law Revision Counsel. 26 USC 2010 Unified Credit Against Estate Tax
Income Tax for the Heir
Royalty Checks Are Ordinary Income
Every royalty check an heir receives is taxable as ordinary income and gets reported on Schedule E. Royalty income from a mineral interest, where you don’t hold a working interest in the extraction operation, is not subject to self-employment tax, so you avoid the additional 15.3% that self-employed earners pay.4Internal Revenue Service.

The Depletion Deduction
Heirs can offset part of the income with the depletion deduction, which recognizes that the underground resource is being used up. The IRS requires calculating depletion two ways and taking the larger result. Most royalty owners use percentage depletion because it doesn’t require knowing original cost basis: you deduct 15% of your gross royalty income from the property. The deduction can’t exceed 65% of your overall taxable income from all sources, and it’s available to independent producers and royalty owners, not to refiners or retailers.5Office of the Law Revision Counsel. 26 USC 613A Limitations on Percentage Depletion in Case of Oil and Gas Wells
The Stepped-Up Basis if You Sell
Inherited mineral rights get a stepped-up tax basis equal to fair market value on the date of death, not whatever the original owner paid.6Office of the Law Revision Counsel. 26 USC 1014 Basis of Property Acquired From a Decedent If a grandparent bought the rights for $10,000 decades ago and they’re worth $200,000 at death, a sale shortly after inheritance at $200,000 produces no taxable gain. Hold the rights longer and the sale price can diverge from the stepped-up basis, creating capital gain or loss when you eventually sell.
The Fractionation Trap
When mineral rights pass through two or three generations without anyone consolidating, the interests fracture into tiny decimal shares. A grandparent’s 1/8 royalty might split among four children, then a dozen grandchildren, until each heir’s check barely covers the cost of cashing it.
Small checks are only part of the problem. Operators sometimes won’t negotiate new leases when they’d need signatures from dozens of scattered fractional owners, and many won’t cut checks below a minimum dollar threshold, so payments pile up in suspense. Interests get lost, and the money escheats.
Preventing fractionation takes deliberate planning. Placing minerals in a trust or family LLC keeps the interest unified under one entity no matter how many beneficiaries exist. If the interests have already split, heirs can consolidate by buying out family members or assigning their shares to a single person or entity. A mineral deed and recording fee cost very little compared to the value lost when a producing interest becomes unmanageable.
