International Arbitration & Trade

Drawing on a team of more than 30 lawyers globally, Weil represents both private parties and sovereign clients in high-stakes and cutting-edge international arbitration cases. Our team of talented, culturally and geographically diverse litigators is well-known not only for its arbitral advocacy but also for its experience in alternative dispute resolution techniques and political advocacy, which enable us to achieve exceptional, creative solutions for our clients in jurisdictions around the world.

At Weil, international arbitration is not simply litigation in another forum but a highly specialized practice, requiring a special blend of advocacy skills, cultural and comparative law expertise, and understanding of international commerce and investment. The lawyers on our team combine top trial skills and experience, deep knowledge of international arbitration law and procedure, expertise across a broad range of industries and substantive areas of law, and the ability to work fluently in multiple languages.
  • We have tried and won arbitrations under all the major arbitral and trade institutions, including: the ICC (International Chamber of Commerce); ICSID (International Centre for Settlement of Investment Disputes); LCIA (London Court of International Arbitration); ICDR (International Centre for Dispute Resolution); AAA (American Arbitration Association); SCC (Arbitration Institute of the Stockholm Chamber of Commerce); HKIAC (Hong Kong International Arbitration Centre); SIAC (Singapore International Arbitration Centre); as well as numerous ad hoc arbitrations under UNCITRAL and other rules.
  • We have leading industry experience in a broad range of sectors, including oil, gas, power and renewables, life sciences, media and telecommunications, mining, financial services, hospitality, and lumber.
  • We conduct our own advocacy, which is standard for us but not for the majority of firms, especially in the United Kingdom, which typically hire out to the Bar.
  • Our team is among the most multicultural, multi-ethnic, multilingual, and multijurisdictional of the leading international arbitration firms, and our attorneys work fluently in multiple languages, such as Spanish, Portuguese, French, Hungarian, Czech, Polish, and German.

Many of our lawyers have held high-ranking government positions, taught international arbitration in the world’s leading universities, and sat as arbitrators. 

We are skilled and creative negotiators who understand and focus relentlessly on our clients' goals, and often achieve successful early resolution of disputes.

We have world-leading practices in:

International Commercial Arbitration

Few firms can compete with the diversity of our practice in international commercial arbitration or our more than four decades of success. We combine unparalleled knowledge of the law of international arbitration with deep knowledge of the substantive law, industry, and region at issue.

Investor-State Arbitration

As one of the world’s most successful firms in investor-state arbitration, we have handled many of the highest-value and most complex cases in the field.

International Trade

Our lawyers have experience in all of the different kinds of dispute settlement provided for in modern trade agreements: State-State, Investor-State, and Trader-State (of the type provided for in NAFTA Chapter 19). They have represented both States and private parties, and their representation of States includes experience both as “in-house” government lawyers and outside counsel. This range of perspectives in a single law firm is rare.
