Denton County business disputes, from Lewisville to Denton.

Denton County civil cases are heard in the courts in Denton, the county seat. Appeals go to the Second Court of Appeals in Fort Worth, and a Denton County business that files bankruptcy does so in the Eastern District of Texas, not the Northern.

Frisco and Carrollton lie partly in Denton County and partly in Collin or Dallas County, so the same city can send a case to two different courthouses and two different courts of appeals. See Lewisville, Carrollton and Frisco.

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.

Checked against each court’s own rules and orders on 5 November 2026 for John Henry’s talk “AI in Modern Litigation” at the Eastern District of Texas Bankruptcy Bench Bar Conference. Rules change; the full reference, with every order cited, is on the AI in litigation page.
