International Arbitration and Global Dispute Resolution

Sullivan & Cromwell’s International Arbitration and Global Dispute Resolution Practice has earned a reputation as one of the world’s leading practices in this field. When disputes cross borders, especially in complex and noteworthy matters, clients rely on us to direct global strategy and work with local counsel to achieve commercial solutions.

We are experienced in arbitrations, litigations, restructurings and government investigations, and we have a long history representing clients in disputes involving Latin America. Our experience covers both commercial and investor-state disputes, and we have particular expertise handling disputes arising from joint ventures and large-scale projects in mining, energy and infrastructure. We also advise on international transactions, identifying litigation risks before they arise and crafting arbitration clause solutions.

We have handled arbitrations administered by all of the major arbitral institutions, including the International Centre for Dispute Resolution (ICDR), the International Chamber of Commerce (ICC), the United Nations Commission on International Trade Law (UNCITRAL), the International Centre for Settlement of Investment Disputes (ICSID), the London Court of International Arbitration (LCIA) and the Hong Kong International Arbitration Centre (HKIAC). We also have substantial experience in arbitrations governed by foreign law and our team includes lawyers trained and qualified in both civil and common law jurisdictions.

S&C’s standing in the field of international arbitration is reflected in the number of major multinational companies that it has represented in commercial or investor-state arbitrations or related dispute resolution matters. Our international arbitration experience is global in nature, involving parties from all regions of the world, including:
