Hicks Thomas: The Houston Litigation Firm That Defended the 825,000-Acre King Ranch

Origin and Background

Taylor Hicks Jr., John B. Thomas, and O. Clayton Lilienstern founded Hicks Thomas in Houston in 1997 around a stated business-first approach to litigation. Lilienstern passed away in 2021, and the firm marked its 25th anniversary in 2022 having expanded more than fivefold from its original founding team, adding offices in Austin, Beaumont, Amarillo, and Sacramento, California, while keeping its headquarters in Houston’s central business district. Co-founder John Thomas has described the firm’s guiding approach as two standing questions asked of every client: “What can we do to help?” and “What can we do better?”

Practice Concentration

Hicks Thomas is a litigation boutique representing both plaintiffs and defendants in business and tort litigation, with particular depth in oil and gas, environmental and toxic tort, antitrust, employment and labor, construction, products liability, corporate governance, securities, banking, insurance coverage, and trade-secret disputes. The Houston office alone carries 23 lawyers across commercial litigation, environmental litigation, energy, and a dozen other practice areas. The firm’s own website discloses that, unless otherwise noted, its lawyers are not certified by the Texas Board of Legal Specialization — a direct disclosure Awesome Attorneys treats as the operative fact on certification status. See this Houston Business Litigation directory for how this litigation boutique compares to other commercial firms serving Harris County.

Notable Work / Track Record

Hicks Thomas is well known in Texas for successfully defending the King Ranch — at roughly 825,000 acres, the largest ranch in the continental United States — in litigation tied to the property’s 120-year history. The firm reports a Tier 1, top-ranking recognition for oil and gas law both nationally and in the Houston metro area from Best Lawyers’ 2024 Best Law Firms list, along with a top-tier ranking for its Houston commercial litigation practice; it was separately recognized that year for energy law, environmental law, management-side labor law, construction litigation, IP litigation, and appellate work. These are firm- and publication-reported recognitions and case outcomes; case results in complex commercial litigation depend on the specific facts involved, and past results do not guarantee similar outcomes in any other case.

Client Voice

Awesome Attorneys did not identify a public consumer-review presence specific to Hicks Thomas as a firm, consistent with a boutique that represents corporate and institutional clients rather than individual consumers. Several Hicks Thomas attorneys carry Martindale-Hubbell peer-review ratings and Avvo’s “Notable” ethical-standards designation, both third-party, peer-sourced signals rather than client-submitted star reviews.

Beyond the Courtroom

Awesome Attorneys did not identify a substantial published record of firm-wide civic, nonprofit, or pro bono activity for Hicks Thomas — a genuine gap for a firm approaching 30 years in practice, disclosed here rather than glossed over. The firm’s public content is concentrated on litigation results, attorney recognitions, and legal commentary.

Recognition for This Houston Business Litigation Firm

Hicks Thomas is ranked by Chambers USA for general commercial litigation in the Houston area, a peer-review-based ranking rather than a paid marketing placement, with partners John B. Thomas, Courtney Ervin, and Robin Harrison individually recognized in the firm’s 2026 Chambers commercial litigation listing. Eight Hicks Thomas attorneys were named to the 2026 Lawdragon 500 X “Next Generation” list, and six partners appear on Lawdragon’s Global Leaders in Energy list. As the firm itself discloses, its attorneys are not TBLS board certified unless individually noted, so Awesome Attorneys does not apply “specialist” language to this profile, consistent with house policy reserving that term for documented TBLS certification.

Texas Legal Backdrop

Most Texas breach-of-contract claims carry a four-year limitations period, while fraud and breach-of-fiduciary-duty claims are separately subject to a four-year period under Texas Civil Practice & Remedies Code § 16.004. Trade-secret misappropriation claims, one of the firm’s stated practice areas, are governed by the Texas Uniform Trade Secrets Act (Civil Practice & Remedies Code Chapter 134A), which carries a three-year limitations period. Oil-and-gas litigation in Texas frequently implicates the state’s rule-of-capture doctrine and the Texas Natural Resources Code alongside general contract and tort law. A prevailing party’s right to recover attorney’s fees on many contract claims runs through Chapter 38 of the Civil Practice & Remedies Code. Complex commercial cases above statutory dollar thresholds may now also be eligible for the Texas Business Court, a specialized trial court that began operating in September 2024. None of this is legal advice; a specific business dispute should be evaluated by a licensed Texas attorney based on the actual facts involved.

Awesome Attorneys Assessment

Hicks Thomas’s clearest differentiator is nearly 30 years of two-sided, business-first litigation practice with genuine national-caliber wins — the King Ranch defense chief among them — and Chambers-verified peer recognition in Houston commercial litigation specifically. The honest trade-off is the firm’s own disclosed certification status: unlike some competitors in this category, its attorneys are generally not TBLS board certified, so prospective clients weighing that specific credential should look elsewhere, even though the firm’s Chambers rankings and Best Lawyers Tier 1 recognitions speak to a different, peer-reviewed form of validation. For a company facing complex energy, environmental, or commercial litigation that values a firm’s trial record and industry-specific depth over individual board certification, Hicks Thomas’s three-decade track record is a reasonable basis for a shortlist.
