Graham has been practicing law since 1983, when he qualified in the UK as a Solicitor of the Supreme Court of England and Wales and has over 35 years legal experience. He was called to the Cayman Islands Bar in 1987 and has over 30 years of experience specifically advising and representing his clients in the Cayman Islands.
In 1992, with Ian Paget-Brown QC and the late Charles Quin QC (who later became a Grand Court Judge), Graham co-founded the firm of Paget-Brown, Quin and Hampson, which in 1995 became Quin and Hampson. Quin and Hampson later merged with the Channel Islands firm of Mourant Ozannes in 2006.
After a short early retirement, Graham was drawn back to the practice of law by his clients and in 2010 he established with Paul Keeble the firm of Hampson and Company. Graham is a well-respected figure in the local Cayman Islands legal community and particularly as a litigator. His experience includes appearances in all court levels and tribunals of the Cayman Islands and attendances at the Privy Council in London, the ultimate appellate body for the Cayman Islands. He has appeared in many decisions reported in the Cayman Islands Law Reports.
In his early career, a large part of Graham’s practice was focused on criminal work. While he still represents clients who have, largely inadvertently, fallen afoul of the law, his practice now focusses principally on advice and representation in high net-worth divorces (including all related family issues) and employment law, but he also advises in a wide array of general matters.
Graham is a skilled negotiator and where possible he seeks to resolve his clients’ legal problems through discussion and negotiation, seeking an amicable resolution and keeping them out of court.
One of Graham’s most significant cases (Crawford v. Sagicor) lasted some eight years and changed some 300 years of established common law as it relates to the tort of civil malicious prosecution. It is reported in the Cayman Islands as 2013 (2) CILR 135 and in the UK as  UKPC 17.
