Stephen Lewis, who has spent much of his time work in a consultancy role on a Clifford Chance project since he left Price Waterhouse in 1998, is a chartered accountant specialising in damages assessment and financial investigations.
He says he will help the legal teams on the financial front at all stages of the litigation process and in financial investigations.
He adds: "It is an exciting time to join Clifford Chance following the merger and a unique opportunity for a forensic accountant to work closely with lawyer in assisting clients."
The firm's litigation and dispute resolution head, John Potts says: "Stephen's background and experience will be an important resource in providing advice to our clients and in enabling us to use outside accountants more efficiently.
"The Woolf reforms have meant that we need additional financial expertise throughout our cases other than from appointed experts.
