Mary Beth received the Insurance Lawyer of the Year award from Benchmark Litigation in 2016 and is consistently recognized as one of its “Top 250 Women in Litigation” in the U.S., in which market commentators have noted that “Mary Beth knows the insurers, they know her, and she has the intimate idiosyncrasies of practice on lockdown. Beyond that, she knows how to try a case, and she will often get brought in . . . when a case looks like it could go all the way.” Another commentator described Mary Beth “as elite as they come,” adding that “her experience is so vast that she can advise on any legal issue.” She is consistently recognized by Chambers USA, which describes her as “an accomplished trial lawyer and insurance expert” and “a formidable, strong, very organized and well-prepared practitioner” “impressive on litigation strategy and get[ting] results” who “knows coverage inside and out, is good at taking a holistic approach to the most strategic options and know[s] what facts we can marshal to best make them work.” She is recommended by The Legal 500, which describes her as “talented”; and “exemplify[ying] the firm’s best qualities.” She is also consistently recognized by Euromoney’s Benchmark Litigation as a National “Litigation Star” in Insurance Litigation and a “New York Star,” where sources say “in this celebrated practice, Mary Beth Forshaw is referenced by most peers in the field as the true go-to. She is like a guru in this world.” In addition, she has been recognized by The Best Lawyers in America, Euromoney’s Guide to the World’s Leading Insurance and Reinsurance Lawyers, and Who’s Who Legal: Insurance & Reinsurance.
