About
Stephen is a highly experienced commercial litigation specialist with over 30 years’ expertise in handling contractual and company disputes, fraud, banking and finance cases, and arbitration. His work in company disputes frequently involves post-M&A issues and director and shareholder conflicts.
Stephen’s cases are often complex, high-value, and international in scope. Cross-border litigation is a key area of focus for Stephen, with a particular focus on Italy and the Benelux countries, and as a result many of his clients are based overseas. He regularly travels across Europe to meet with clients and attends international conferences. Stephen heads our UK/USA disputes team advising US lawyers and parties with litigation or disputes in England.
Stephen is skilled in the strategy and tactics integral to dispute resolution. He takes a commercial approach, aiming to resolve disputes efficiently and cost-effectively, with a strong commitment to achieving outcomes that align with his clients’ best interests.
Stephen is a member of the Commercial Litigation Association, the Financial Services Lawyers Association, the Fraud Advisory Panel, the London Solicitors Litigation Association, and the International Bar Association. Stephen has been recognised by The Lawyer magazine as a “Hot 100” lawyer in litigation.
