Collin County business disputes, from Plano to McKinney.

The Collin County district courts and county courts at law sit in McKinney. Parts of Plano and Frisco lie in Denton County, so where a company is located does not always settle which county a case belongs in. A case about land is filed where the land is. Appeals from Collin County go to the Fifth Court of Appeals in Dallas.

Many disputes here are between owners of a closely held company, or between a company and someone who left it. See partner and owner disputes and non-compete litigation. Town pages: Plano, McKinney, Frisco and Richardson.

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.

Collin County. The County Courts at Law require disclosure of AI use and a certificate covering every citation; the district courts require verification.

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.
