Trey Cox is an accomplished and sought after advocate and trial lawyer and Co-Partner-In-Charge of the Dallas office.  He has spent his entire professional life as a courtroom attorney and litigator helping clients resolve large, complicated and often high-profile business disputes.  His courtroom experience is broad and extensive.  He has tried over 35 cases involving trade secrets, breach of fiduciary duty, securities fraud, product liability, trademark, insurance coverage, energy, oil and gas and partnership disputes.  He has achieved success for a variety of clients – both defendants and plaintiffs, from big energy companies to a lone individual businessman battling the odds.

Mr. Cox is consistently recognized as one of the top commercial trial lawyers in America. Chambers USA reports that Mr. Cox is “an excellent trial lawyer who is great with clients and on his feet.” A client says: “He’s extremely well prepared and a great presenter who brings a lot of energy and focus. He’s very impressive.”  Recognized for many years by Chambers USA as a “Leader in His Field,” Chamber USA elevated Mr. Cox to its most elite “Band 1” category as one of a handful of the leading trial lawyers in Texas and singled out Mr. Cox in the Texas Trial Lawyers “Spotlight Table,” a recognition given to individuals to highlight them as a select group for their particular achievement. Mr. Cox is the youngest trial lawyer in Texas history ever to be so spotlighted.

For over a decade, he’s been listed as one of the “Best Lawyers In America”, one of the “Top 100 Super Lawyers in Texas” and a Benchmark Litigation Star.  He is a fellow of the American Board of Trial Advocates and the Litigation Counsel of America.  His jury trial experience and courtroom success have earned him the distinction of being double Board Certified in Civil Trial and Civil Pre-Trial by the National Board of Trial Advocacy.

Mr. Cox’s cases have been featured in The Wall Street Journal, The New York Times, The Los Angeles Times, The Dallas Morning News, Bloomberg News and the Houston Chronicle, among many other publications. His last trial – a commercial plaintiff-side partnership dispute – was recently recognized as one of the Top 20 Verdicts in Texas.  His trial experience provides a real advantage in focusing the entire preparation process on what matters most – how to effectively and efficiently marshal the proof to prevail on the key issues.

Trey received a B.A., magna cum laude, from Washington & Lee University, and his J.D., with honors, from the University of Virginia School of Law. After graduation, Trey clerked for the U.S. Court of Appeals for the Fifth Circuit.

  • Texas courts are bracing for a flood of trade secret litigation. And while COVID rattles the economy, corporations are gearing up for the inevitable. Laid-off workers and insecure home offices threaten to leak confidential information at volumes unseen since the Great Recession. Texas is already the No. 1 trade secret hotspot in America, boasting close to 20 percent of all decisions nationwide. Authored by experienced Texas trial lawyers, Texas Trade Secret Litigation is the only manual in print for this fast-growing area of intellectual property law. Trey Cox and Chris Patton provide a step-by-step guidebook covering statutes, procedure, and overall litigation strategy. Fully updated with case law and sample forms, Texas Trade Secret Litigation is the essential reference for lawyers contending with the increasing trade secret docket in Texas courts. , Co-Authored with Chris Patton , Texas Trade Secret Litigation, A step-by-step guidebook covering statutes, procedures, and overall litigation strategy , Full Court Press , Legal, 2020
  • This book was tailor-built to help trial lawyers prepare for, make, and respond to evidentiary objections. It is designed to be used for quick reference on the go in the courtroom and to consult at length in your office. The Rules of Evidence can be tricky in practice. There are numerous "cheat sheets" that print all the rules on one page, but don't provide any additional guidance and are in difficult-to-read fine print. On the other hand, there are treatises packed full of case law and helpful materials, but those are cumbersome to use. This book is meant to fill that gap and be the go-to practical resource for trial lawyers., Co-Authored with John Adams , Mastering Federal Evidence, Trial Advantage Press, Legal, 2022
  • Recovering attorneys' fees can no longer be an afterthought for trial lawyers and their clients. Today, the ability to recover attorneys' fees may be the deciding factor in whether or not to file a lawsuit and almost always plays a critical role in the decision to settle or try a case. In fact, it is no longer unusual for an attorneys' fees recovery to exceed actual damages. Mindful of this change in the attorneys' fees landscape, attorneys' fees experts Trey Cox and Jason Dennis have authored How to Recover Attorneys' Fees in Texas -- a complete, step-by-step guide for practicing attorneys to help them win and defeat attorneys' fees claims at trial., Co-Authored with Jason Dennis , How to Recover Attorneys’ Fees in Texas, Published by ALM, Legal, 2022
