International Dispute Resolution

Diamond McCarthy’s International Dispute Resolution practice features a highly skilled, hands-on team focused on international arbitration, arbitration-related litigation, and cross-border disputes with complex issues and substantial dollar amounts at stake. 

Our practice covers complex cross-border work providing advice and advocacy for private parties, sovereign States, and State entities. The practice works closely with our business and insolvency litigation practice groups, leveraging their experience to assist clients with claims across jurisdictions worldwide. The firm regularly handles bet-the-company cases across a variety of industries, under all major international arbitration rules and before all major arbitral institutions. 

We have deep experience in international commercial arbitration, investment treaty arbitration, and transnational litigation work, with a special focus on energy and natural resources, construction and infrastructure, telecommunications, media and technology, and finance. Our counsel draw on their experience working at elite international law firms, major arbitral institutions, and international courts, as well as their experience acting as arbitrators, to achieve successful results for clients. 

Our energy and natural resources work has evolved significantly over decades of representing clients from our origins in the oil patch of Texas. Today, our counsel represent clients in international disputes across the globe, with matters in Latin America, Europe, Africa, the Middle East, the CIS, and Asia.  

In addition to its international work, the firm has an established record in arbitration-related court proceedings in the U.S., the U.K., Europe, the Caribbean, and various other jurisdictions. We represent parties in proceedings for enforcement and vacatur of arbitral awards, as well as discovery under 28 U.S.C. § 1782 in aid of foreign litigation. 

Our diverse client list includes sovereign governments, Fortune 500 and FTSE 100 companies, multinational corporations, financial institutions, high-net-worth individuals, international liquidators, and various players in bankruptcy and insolvency proceedings, from trustees and receivers to creditors and investors. 

As a boutique of experienced lawyers with deep international practice, we offer clients strategic, effective advice and advocacy in disputes that cross legal systems, political landscapes, and cultural contexts.
