Stuart H. Singer

Since January 2024, Stuart has been one of Boies Schiller Flexner’s three managing partners and since 2017, a member of the firm’s Executive Committee. In 2000, Stuart co-founded what became the first South Florida office of the firm.

During his 25 years as a litigation partner at BSF, Stuart has handled trials, arbitrations, and appellate cases across the country. He was described by Chambers USA, as having a “fantastic courtroom presence” and being “among the best trial lawyers in the country.” Lawdragon called Stuart “a dazzling advocate in trial and appellate courts,” who is relied on “to win big when it matters.” Stuart has accomplished that for numerous Fortune 500 companies, as well as smaller businesses, individuals, and nonprofit organizations. On the plaintiffs’ side, Stuart has served as lead counsel in antitrust and securities representations that have recovered over $1 billion.

Stuart’s experience covers a wide variety of subjects, including breach of contract, antitrust, securities, energy, class action defense, civil fraud, unfair trade practices, professional liability defense, constitutional business law and health care. For over 15 years, Stuart has successfully represented the nation’s largest renewable energy company, largest utility, number one cruise line, largest title insurance business, and one of the country’s preeminent law firms.

Stuart has been recognized by clients and peers as one of the top lawyers in the nation. For over 15, years he has had tier one ranking by Chamber & Partners in antitrust and commercial litigation, is listed in Best Lawyers in America for commercial litigation, antitrust, and bet-the-company litigation, and has been included in Lawdragon’s list of the country’s 500 leading lawyers. He has won multiple Most Effective Lawyer awards from the Daily Business Review and has twice been named The American Lawyer’s Litigator of the Week.

Recent cases have included invalidating a Texas law on building transmission lines as violative of the Commerce Clause, defeating class certification in a lawsuit against Florida’s leading utility seeking billions of dollars following Hurricane Irma, winning an arbitration for a leading producer of sports trading cards against an attempted termination of its license, winning a directed verdict eliminating a potential $800 million damage claim in a two-month long jury trial in a professional liability case against one of the country’s top law firms, obtaining a Fifth Circuit ruling upholding broad immunity for lawyers, and winning a jury verdict with full damages in a fraud suit for a Fortune 500 company. 

Stuart led the firm’s 10-year pro bono case on behalf of Florida’s children on Medicaid, which resulted in improved access to medical and dental care for a class of 2 million children and thus “may have changed more lives than any U.S. litigation of the past decade” (Lawdragon).
