AZA is home to true courtroom lawyers who provide clients with a formidable track record in complex business and energy disputes.

Based on AZA’s results in 2014, Texas Lawyer named AZA as the 2015 Litigation Department of the Year for law firms having under 35 lawyers. This award follows Law360  naming AZA to the list of Texas Powerhouse Law Firms.

AZA was named First-Tier in Commercial Litigation in Houston by U.S.News & World Report and The Best Lawyers in America in their rankings of the nation’s leading law firms. AZA earned a coveted rating for its work in Texas commercial litigation in the 2015 edition of Chambers USA: America’s Leading Lawyers for Business, published by Chambers and Partners, which is recognized worldwide for its prestigious guides to the legal profession.

AZA was one of only 32 firms in the U.S. to be recognized as “Awesome Opponents” in a nationwide poll of corporate general counsel who were asked to name the law firms they hope their companies never have to face in court.

AZA earned a spot on the BTI Client Service A-Team, a ranking of law firms based on client service interviews with corporate counsel from across the nation.

AZA won three of Texas’ Top Verdicts in one year. One was a take-nothing defense verdict with an award against the plaintiff for all of our client’s attorneys’ fees. Another was an enormous patent win, and the third was a client victory in a defamation case, proving AZA’s winning ways on both sides of the bar.

Our lawyers are from top 10 law schools and are at the top of their class, and our partners previously practiced at Baker Botts and Vinson & Elkins. We not only recruit the best and brightest out of law school, we recruit the top talent from other firms as well. We routinely draw associates from the top multinational law firms.

AZA's office is conveniently located in downtown Houston at One Houston Center, recently renamed LydondellBasell Tower. The firm offers services in English, Spanish, Greek, Farsi, French, Mandarin, Bengali, Russian and Ukrainian.
