Quinn Emanuel has one of the pre-eminent arbitration practices, globally, befitting of our position as the largest business disputes firm in the world. The Wall Street Journal describes us as a “global force in business litigation,” and international arbitration is one of the cornerstones of our practice. Our international arbitration practice includes:

• International commercial arbitration
• U.S. and other domestic arbitration
• Investment treaty arbitration
• International arbitrations between sovereign states

The firm has international arbitration experts in all of its offices, offering specialism in both common law and civil law traditions, and expertise in all of the major languages in which international arbitration is commonly conducted. We operate as a single, integrated team. We represent companies, including some of the world’s largest companies, States and state-owned entities, and high net worth individuals. We practice in all of the world’s major arbitration centres, and under all major applicable legal systems, including public international law. Our lawyers have decades of experience in handling disputes both as counsel and arbitrators under all major international arbitration rules, including:

• International Chamber of Commerce (ICC)
• London Court of International Arbitration (LCIA)
• American Arbitration Association (AAA)
• International Centre for Dispute Resolution (ICDR)

We arbitrate and try more cases per year than any other firm. This gives us an outcome-driven perspective, which creates cost-efficiencies without sacrificing quality. Our “end game” perspective extends to related court proceedings, allowing us to best position our clients in the myriad forms of litigation—from compelling arbitration, to discovery requests, to challenging and enforcing arbitral awards—that often accompanies complex international arbitration proceedings. We also understand that the best outcome for a given client may not always be an award after a full hearing. We take seriously our responsibility to devise and fashion creative mechanisms to settle international arbitration disputes in a manner that will best achieve our client’s objectives.
