About William J. Moore

Pragmatic and business-minded, William Moore is a trial lawyer who knows that not all disputes need to be resolved before judges and juries. As he represents high-net-worth individuals, private equity firms and private and public companies in business conflicts, he hones in on his clients' priorities, shields them from extraneous noise and works with them on developing a pathway to resolution as efficient as it is favorable. When they choose to go to trial, clients trust Will's courtroom experience, which includes multimillion-dollar jury verdicts and precedent-setting rulings, to give them the best chance to prevail.

Communication that prevents inertia

Will has particular experience in post-closing merger and acquisition (M&A) disputes, including those arising from representations and warranties, working capital adjustments and earnouts. To prevent these and other cases from dragging on due simply to lawsuit inertia, he stays in regular contact with his clients to ensure that he is always advancing their particular interests in a case. Whether he's representing clients in the financial services, energy, real estate, hospitality or retail sectors, he wants them to know that he’s their business partner.

Will is not just a litigator, he's a trial lawyer. He has won multiple jury verdicts, including a $2.8 million verdict for an investment firm in a high-profile dispute between the firm and a former executive that established new law on the recovery of attorneys' fees in Texas. Significant legal developments have resulted from his cases, like his representation of a lender in a bankruptcy trial that established important new precedent for parties that finance oil and gas development projects.
