McMullen County Mineral Rights and Unclaimed Royalties: A Guide for Heirs

What families should know

McMullen County, around Tilden, has one of the smallest populations in Texas but substantial Eagle Ford oil development. Most mineral owners are descendants of ranch families who now live elsewhere.

Royalties typically stop shortly after an owner's death, because operators will not pay a deceased owner's account until someone proves who now owns the interest. If no one does, the funds remain in suspense, and after long enough the operator must report and deliver them to the Texas Comptroller as unclaimed property. In either case the money still belongs to the owner's heirs or devisees.

The work is the same whether the family still lives near Tilden or has scattered across the country: identify the interest, establish each link in the chain of inheritance, record the right instruments in McMullen County, and deliver them to the operator.

The legal detail

Development in McMullen County

Eagle Ford wells are typically drilled on pooled units combining several tracts, so royalty is allocated to each tract by its share of the unit when the leases authorize pooling. Many South Texas ranches were partitioned among children or sold with mineral reservations, which means a family's interest may lie under land it no longer owns.

Where title is proved

Ownership of minerals in McMullen County is proved in the McMullen County deed records, kept by the county clerk in Tilden. A probate generally takes place in the county where the decedent lived, so a family whose relative died in Houston or out of state will probate there and then record certified copies of the will and order in McMullen County. When there is no will, a recorded affidavit of heirship is evidence of the family history, and after five years of record it is prima facie evidence of the facts stated (Tex. Est. Code § 203.001). When an operator or title insurer requires a court order, a determination of heirship under Chapter 202 produces a binding judgment that can be recorded in McMullen County.

Suspended funds and the Comptroller

An operator may withhold royalties without interest while a title requirement concerning the owner's identity or title is unsatisfied after a reasonable request for curative information (Tex. Nat. Res. Code § 91.402(b)). Funds unclaimed for more than three years are generally presumed abandoned and delivered to the Comptroller (Tex. Prop. Code § 72.101), where heirs may claim them with proof of their right (§ 74.501).

Frequently asked questions

How do I find out whether my family owns minerals in McMullen County?

Search the McMullen County deed records (kept by the county clerk in Tilden) for conveyances and reservations in your relatives' names, check the appraisal district's mineral roll for producing interests, use the Railroad Commission's public GIS viewer to locate wells and operators, and search ClaimItTexas.gov for proceeds already sent to the State.

Do we have to probate the estate in McMullen County?

Not necessarily. A will is generally probated in the county where the decedent lived, which may be elsewhere in Texas or out of state. What matters in McMullen County is that the probate order, muniment of title, affidavit of heirship or heirship judgment is recorded in the McMullen County deed records, where operators and title examiners will look for it.

Why is the operator holding our royalties?

Texas law allows a payor to withhold proceeds without interest while a title requirement concerning the owner's identity or title remains unsatisfied after a reasonable request for curative information (Tex. Nat. Res. Code § 91.402(b)). Recording the right instruments and signing new division orders usually releases the funds.

Can we handle this without traveling to Tilden?

Usually. Records can be searched and instruments recorded remotely, and heirs can sign affidavits and division orders before a notary wherever they live.
