Andrew Wass

Partner | London

Andrew is a partner in the litigation and arbitration team, focusing on banking.

He has a particular interest in dispute resolution and restructuring and banking in the financial services arena.

After university, Andrew was called to the Bar in 1986 but subsequently decided to pursue a career outside the law. From 1987-2002 he worked in a variety of industries; the financial markets, television post-production and residential property development. During that time he also ran a private investment portfolio. He returned to the law in early 2002, qualified as a solicitor and has since become experienced in contentious financial services.

Andrew spent more than five years as an inter-dealer broker in the foreign exchange (‘FX’) option market. This experience included establishing and managing a highly successful FX desk in Tokyo. As a former market participant, Andrew has a unique insight into the financial markets and their specialist products. He has used his market experience both as a litigator and a mediator in relation to financial services disputes.

Andrew’s other contentious experience includes professional negligence claims and the sport, civil fraud and defamation sectors. He qualified as a CEDR Mediator in 2006 and has mediated in numerous commercial disputes.
