Lewisville business disputes, in the Denton County courts.

Denton County cases are heard in Denton and appeal to the Second Court of Appeals in Fort Worth, not the Fifth in Dallas — a difference that matters when the cases you are relying on came from one court and not the other.

Lewisville’s businesses sit along I-35E between Dallas and Denton, and a dispute with a Dallas company can raise the question of which county, and so which court of appeals, the case belongs in. A Denton County business that files bankruptcy does so in the Eastern District of Texas. See Denton County.

Texas state courts. No statewide rule on AI is in force. In June 2026 the Supreme Court of Texas preliminarily approved a new Rule 13 under which signing a filing certifies that the signer verified it, including that its citations, quotations and holdings are not fabricated; no final order had issued. The Business Court’s Local Rule 10(c) permits AI but makes the filer independently responsible for every filing. The courts of appeals have no AI rules but sanction fabricated authority under their inherent power, as the Dallas court did in 2025, and Ethics Opinion 705 advises verifying every output, protecting confidences and supervising its use.

Denton County. The probate courts require every filer to certify. The district courts’ posted order requires a certificate if AI was used, and a May 2026 order extending that to every filer had not yet been posted on the state’s site.
