Guy Marrison is counsel in our financial services litigation team. He has experience across a broad range of investment banking and retail disputes, including alleged mis-selling of financial products, claims relating to complex securities, asset finance enforcement and consumer credit claims.

Guy also practices more general commercial litigation and has experience of contract disputes, fraud and asset-tracing, and a broad range of interlocutory applications. This includes applications for summary judgment, asset preservation orders (both in the UK and offshore jurisdictions), security for costs, specific disclosure, anti-suit injunctions and insolvency proceedings. 

Guy's recent experience has included acting for a leading bank in relation to a claim concerning the alleged mis-selling of an interest rate hedging product, in which the court dismissed all claims against the bank at trial. He has also acted for another leading bank, in court and before the Financial Ombudsman Service, in relation to various consumer credit claims (including sections 56, 75 and 140 of the Consumer Credit Act).   

Guy also has experience of regulatory investigations brought by various agencies, including the FCA, SEC, DOJ, EC and JFTC. This has included investigations into alleged bond market manipulation and advising on and responding to various information requests. 

Guy also has particular experience of aircraft finance disputes, including advising on enforcement and recovery and dealing with related court actions (and arbitration) in various onshore and offshore jurisdictions, including China, Hong Kong, Singapore, New York, BVI, Guernsey, and the Isle of Man.

His background in business means Guy has a commercially-driven approach to solving his client’s problems and helping them to achieve their objectives.
