Eagle Ford Mineral Rights: A Guide for Heirs of Karnes, La Salle, Webb, Dimmit and McMullen County Families

What families should know

During the shale boom the Eagle Ford turned quiet ranch country into one of the most active oil and gas regions in the United States. For families with roots in Karnes City, Kenedy, Cotulla, Carrizo Springs, Tilden or Pleasanton, whether they still live nearby or have moved to San Antonio, Houston, Austin or out of state, it also turned old family minerals into royalties.

The title problems are characteristic of the region. Ranches were divided among many children; minerals were reserved when land was sold and then forgotten; owners died without wills, or with wills never probated; and family members now live across the United States and in Mexico. When operators assembled pooled units, every owner in every tract had to be identified. Interests that could not be confirmed were placed in suspense, and some of those funds have since been delivered to the Comptroller as unclaimed property.

Families who still have relatives near the land have an advantage, because those relatives often know the family history and can serve as affiants. Heirs who have moved away can handle nearly all of the work by phone, mail and video.

The legal detail

Pooled units and allocation

Eagle Ford wells are typically drilled on pooled units that combine several tracts. If the governing leases authorize pooling, royalty on unit production is ordinarily allocated to each tract in proportion to its share of the unit, so a family may receive royalties from a well that is not located on its land at all. The decimal on a division order reflects that tract allocation, and checking it requires the unit designation, the lease royalty and the family's fractional ownership.

Suspense, interest and unclaimed property

Operators may withhold payment without interest while a title requirement concerning an owner's title, identity or whereabouts remains unsatisfied after a reasonable request for curative information (Tex. Nat. Res. Code § 91.402(b)). When funds remain unclaimed long enough, the holder must report and deliver them to the Comptroller under the Property Code, and the payor's obligation to pay interest ends on delivery (§ 91.403(c)). Older proceeds should be searched on ClaimItTexas.gov as well as with the operator.

Establishing a multi-generation chain

Each death in the chain must be addressed separately and in order. Where there was no will, the heirs are determined under the descent and distribution law in effect at that death; where there was a will, it generally must be probated. Recorded affidavits of heirship become prima facie evidence of the facts stated after five years of record (Tex. Est. Code § 203.001), and a judicial determination of heirship is available when an operator or title insurer requires a judgment or an heir cannot be located.

Heirs in Mexico

Alienage does not disqualify an heir (Tex. Est. Code § 201.060). Birth, marriage and death records from the Mexican civil registry are commonly required to prove the family history; they should be obtained as certified copies, apostilled, and translated, because operators and title examiners will not rely on informal copies.

Steps for families

  • Search the county appraisal district mineral roll for the relative's name.

  • Search ClaimItTexas.gov for proceeds already delivered to the State.

  • Search the county deed records for reservations, conveyances and any existing heirship or probate instruments.

  • Identify the operator through check stubs, the appraisal roll or Railroad Commission data, and request the title requirement affecting the interest.

  • Prepare and record the probate or heirship instruments for each link in the chain.

  • Deliver recorded copies to the operator and sign new division orders.

Frequently asked questions

Is the Eagle Ford still producing?

Yes. Production continues across the trend from existing wells and ongoing development, and many tracts are held by production under leases signed during the boom.

How do I know whether family land is in the Eagle Ford?

Identify the county and tract, then use the Railroad Commission's public GIS viewer to locate wells and units on or near it. The appraisal district mineral roll for that county will show whether an interest is producing.

Can heirs living in Mexico claim Texas royalties?

Yes. A person is not disqualified from inheriting because he or she, or an ancestor through whom the claim runs, is or was an alien (Tex. Est. Code § 201.060). Mexican civil registry records ordinarily need certified translations and an apostille.

What if several generations died without probate?

Each death must be addressed in sequence, by affidavit of heirship, probate of a will or a judicial determination of heirship, and the instruments recorded in the county where the minerals lie.
