Plano business disputes, from Legacy to the courthouse.

Plano, home to the Legacy business district and many corporate headquarters, lies mostly in Collin County with a small part in Denton County. We take contract, owner, lease and real estate cases for Plano businesses.

What we handle

  • Breach of contract and services agreements
  • Disputes between owners, partners and LLC members
  • Executive departures, non-competes and customer solicitation
  • Office and commercial lease disputes
  • Temporary restraining orders and injunctions
  • Appeals

How we approach it

Collin County civil cases are heard in McKinney, and appeals go to the Fifth Court of Appeals in Dallas. Plano is in the Eastern District of Texas, and the federal court sits in Plano, so a Plano business’s bankruptcy or federal case is often heard in its own city.

Business disputes here can include executive departures, customer solicitation, and disagreements between the owners of a closely held company. See Collin County and non-compete litigation.

The court’s rules on AI

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.
