The considerable international reach of the civil fraud team at PCB Byrne is a boon to its client base of major corporates and ultra-high-net-worth individuals. It has a recent slate of high-profile cases and the team regularly represents clients in the Supreme Court, the Commercial Court, and the Court of Appeal. Leading name in fraud investigation and asset recovery Anthony Riem heads the practice, with Trevor Mascarenhas being another specialist in civil fraud claims, well-versed in precedent-setting cases. Olga Bischof‘s broad practice includes particular experience in offshore jurisdictions, and Ben Davies focuses on high-value fraud litigation. Catherine Eason’s practice continues to develop, and the team was bolstered by the respective additions in February and March 2025 of Simon Colledge from gunnercooke LLP and Matthew Wescott from JMW Solicitors LLP. Elizabeth Seborg left the firm in May 2025.
