Sue Prevezer QC



Our most senior barrister and solicitor and Chair of the firm’s International Trial Practice, Sue Prevezer QC, has over 25 years of experience arguing large complex commercial cases at every level of the UK judicial system and in arbitration, and sits as a Deputy High Court Judge in the Chancery Division of the High Court.  She is also a CEDR Mediator and is admitted to the Bar in both the Cayman and the BVI (where she recently appeared as counsel, leading a Quinn Emanuel team from London and New York and achieving a substantial trial victory in litigation arising out of the Madoff fraud). She won one of the very first judgments handed down by the Supreme Court of the United Kingdom which addressed important contract construction principles, and more recently, a high-profile case in the Court of Appeal, resolving important jurisdictional principles in cases involving multiple agreements with conflicting jurisdiction provisions. She has considerable experience in managing litigation with English and US elements and litigation involving issues of fraud and complex trusts for both corporations and individuals.  She has recent experience in handling extradition matters and acts for a range of clients, including major corporates, funds, investors, trustees and office holders and high net worth individuals. She also has considerable expertise in insolvency related, securitization and restructuring litigation.

Sue has been named a “Leading Individual” by the Legal 500 directory and was recently recognized in both Commercial and Banking Litigation (2013). Legal 500 praised Sue for being a ‘wonderful lawyer’ and a ‘talented and creative adviser’ (2013). The Chambers directory describes her as a “star performer”, “a very talented advocate” and “efficient and pragmatic to deal with”.
