From the 406th Judicial District Court, Webb County, Texas Trial Court No. 2025CVK000491D4 Honorable David E. Garcia, Judge Presiding

Opinion by: Lori Massey Brissette, Justice

Sitting: Irene Rios, Justice Lori Massey Brissette, Justice H. Todd McCray, Justice

Delivered and Filed: July 15, 2026 AFFIRMED This is an interlocutory appeal from an order denying a special appearance of an out-of-

state defendant, Michael Gill. See TEX. CIV. PRAC. & REM. CODE § 51.014(a)(7). After reviewing the parties’ briefs and the trial court record, and after considering oral argument, we affirm the trial court’s order.

BACKGROUND

In 1921, Francz Hamilton Foss bought the mineral interests of thousands of acres of property in Webb County. Foss died in 1959, and her will created a trust. In 1961, a California probate court approved distribution in accordance with the will, directing that trust income be distributed to fifteen beneficiaries in different percentages, with each beneficiary’s share to increase proportionally on the death of any other. The beneficiaries included James Challiss, appellee Jutta Baumgarten’s now-deceased husband. Appellant Michael Gill was one of two trustees. In 1987, Gill and his co-trustee moved to terminate the Foss trust because its mineral interests were not productive. With the consent of all beneficiaries, in 1988 the California probate court terminated the Foss trust and ordered distribution of the trust assets to the beneficiaries. 1 According to Baumgarten, this distribution created a cotenancy to the mineral interests among the nine surviving beneficiaries, including Challiss. Baumgarten asserts that upon termination of the trust, Challiss transformed from a mere income beneficiary to a partial owner of the Webb County mineral interests.

In 2011, over two decades after the California court terminated the Foss trust, Laredo Energy IV LP determined hydrocarbons could be produced from some of the Foss mineral interests in part of Tract 16. Laredo Energy then, evidently unable to contact any of the relevant parties, used Section 64.091 of the Texas Civil Practice & Remedies Code to establish a receivership lease so that it could harvest hydrocarbons from the land and then deposit royalties into a receivership account with the Webb County clerk. 2 About three years later, in 2014, Challiss passed away, and

1 The California court’s 1988 order terminating the trust states the trustees “shall distribute the accumulated income and principal of the trust then remaining to the beneficiaries of the trust.” (emphasis added). 2 Texas law provides a mechanism for appointing a receiver when mineral interest owners cannot be located. A district court can “appoint a receiver for the mineral interest or leasehold interest under a mineral lease owned by a nonresident or absent defendant” in actions “brought by a person claiming or owning an undivided leasehold interest under a mineral lease of land in this state and that has one or more defendants who have, claim, or own an undivided mineral

his surviving spouse, Baumgarten, became heir to his estate. Baumgarten asserts she inherited Challiss’s partial ownership of the Webb County mineral interests.

Gill did not learn of the lease or the account holding the royalties until 2022, when California Inheritance Group notified him that California’s Unclaimed Property Division was holding over $500,000 in royalties payable to the Foss trust, specifically monies paid by Laredo Energy pursuant to the lease created via the receiver. Gill then filed a petition in Los Angeles County Superior Court requesting that he be appointed temporary trustee to marshal the royalties. The court granted Gill’s petition and he became the temporary trustee in fall of 2022. Gill then filed an accounting and a petition to be appointed permanent trustee in part “so that he can continue to marshall [sic] these assets, and engage in legal proceedings in Texas to establish division orders for distribution to the beneficiaries of the Trust.” Gill’s petition asserted that though the trust that had been “dormant” until 2011, the royalties belong to the revived trust. Baumgarten objected to both the accounting and to Gill’s appointment as trustee.

The trust litigation in California is ongoing, with the parties disputing whether the trust can be revived to resume ownership of the mineral interests and gain access and dominion over the royalties received to date and to be received in the future. Gill has asserted in the California court that the 1988 termination order did not extinguish the rights of the trustees and beneficiaries with regard to these mineral interests. Gill has further asserted that Baumgarten may only be entitled to a percentage of the royalties from the beginning of the 2011 lease until Challiss’s death in 2014, at which time—assuming the trust is still in place—Challiss’s royalty interest would have passed

interest in the same property.” TEX. CIV. PRAC. & REM. CODE § 64.091. To obtain appointment of a receiver under this section, a plaintiff energy company must prove that (1) it “has made a diligent but unsuccessful effort to locate the defendant” and (2) it “will suffer substantial damage or injury unless the receiver is appointed.” Clay Expl., Inc. v. Santa Rosa Operating, LLC, 442 S.W.3d 795, 799 (Tex. App.—Houston [14th Dist.] 2014, no pet.) (quoting TEX. CIV. PRAC. & REM. CODE § 64.091).

pro rata to the remaining beneficiaries, increasing their interests and leaving nothing to be inherited by Baumgarten. In contrast, Baumgarten asserts that because the trust was terminated in 1988 and its assets were distributed to Challiss and the other beneficiaries, upon Challiss’s death in 2014 she became and remains a part owner of the mineral interests.

To address the issue of ownership of the Texas mineral interests, Baumgarten sued Gill and five other defendants in Webb County. In her live pleading, Baumgarten asserts the following claims against Gill: (1) trespass to try title; (2) accounting; and (3) breach of fiduciary duty. Gill responded by filing a special appearance which the trial court denied. Gill timely appealed the jurisdictional issue.

PERSONAL JURISDICTION

On appeal, Gill argues the trial court erred in denying his special appearance because the trial court does not have specific personal jurisdiction over him. Specifically, Gill asserts Baumgarten’s claims are based on conduct which occurred in California and that by such conduct he did not purposefully avail himself of the privilege of conducting any activities in Texas. In contrast, Baumgarten asserts Gill subjected himself to jurisdiction in Texas by attempting to “hijack[]” and modify ownership of royalties generated in Texas. 3
