In Texas, the insurance industry is a major economic driver, but it is also a source of frequent legal disputes between policyholders and powerful insurance carriers. Whether it is a bad faith denial of a storm damage claim, a complex commercial coverage dispute, or a failure to defend a liability lawsuit, Texans require aggressive legal representation to ensure that insurance companies honor their contractual obligations and comply with the Texas Insurance Code.

Insurance practices in Texas are primarily governed by the Texas Insurance Code, which includes critical consumer protections. Under Chapter 541 (Unfair Methods of Competition and Unfair or Deceptive Acts or Practices), insurers are prohibited from misrepresenting policy provisions or failing to attempt good-faith settlements when liability is reasonably clear. Chapter 542, known as the Texas Prompt Payment of Claims Act, mandates strict timelines for insurers to acknowledge, investigate, and pay or reject a claim—failure to comply can result in the insurer being liable for 18% annual interest and attorney fees. As of January 1, 2026, new reporting mandates under House Bill 2067 require insurers to provide policyholders with detailed written statements for any declination, cancellation, or non-renewal of property and casualty policies.
The firms listed on this page represent a selection of insurance practices operating across Texas.
