Jason Masimore, a former federal prosecutor with the U.S. Department of Justice, Southern District of New York, is an experienced trial lawyer and highly sought-after investigator who represents institutions, trustees, politically-exposed persons, and ultra-high-net-worth individuals in complex international criminal and civil matters involving allegations of corruption, fraud and money laundering, including representing those who have been, or expect they might be, sanctioned by the U.S., UK, and/or EU. Testimonials in Chambers have described him as a “closer of deals” who is “extremely clever and has a very sharp mind,” “thoughtful and considered, . . . not just a pit bull,” and “tactically one of the best lawyers I’ve come across.” His in-court examinations have been described by The New Yorker as “devastating,” and his trial advocacy has been recognized in the book, Doing Justice, by former U.S. Attorney Preet Bharara, as showing “a masterful understanding of what other people need[ ] to understand, in an instant.”
Based full-time in London, Mr. Masimore’s work with international private clients and on investigations has involved complex matters across North America, Europe, Africa, the Middle East, Asia and various offshore jurisdictions, including the British Virgin Islands, the Cayman Islands, the Bahamas, the Republic of the Marshall Islands, the Cook Islands, the Bailiwick of Jersey and the Republic of Seychelles, among others.
Calling upon his experience as a former prosecutor, Mr. Masimore also assists corporate and individual clients in developing international, multi-jurisdictional offensive and counter-offensive strategies in connection with high-stakes business problems as well as in response to allegations of fraud or otherwise of a criminal nature.
