Practice Areas

International Litigation and Cross Border Disputes

In today’s global marketplace, businesses need a legal partner with experience in resolving complex disputes or defending against governmental inquiries across multiple jurisdictions. Dontzin Nagy & Fleissig has represented clients in more than 20 countries with respect to cross-border disputes, litigation, investigations, and transactional matters.

Our lawyers regularly handle international investigations, including insider trading cases before regulatory authorities throughout Europe. We also represent clients in cross-border disputes between parties outside of the United States. The firm’s experience in these matters stretches from the UK to France, Germany, Luxembourg, Spain, South Africa, and Saudi Arabia, as well as the Cayman and British Virgin Islands.

Our core strength is in bringing US litigation tactics to bear in international jurisdictions. We believe that cases are won on the facts — and thus we are intensely focused on investigations and fact-finding prior to trial. The facts-driven litigation behind our international practice has produced a track record of positive outcomes for clients around the globe.

While our bench has extensive experience litigating matters internationally, we represent large, multinational clients efficiently and cost-effectively by integrating a global network of lawyers and other professionals in a wide array of practice areas — including tax and corporate law — throughout Europe, the Middle East, and Africa.
