International Arbitration

Our lawyers have extensive experience of conducting arbitrations in London and abroad. We act for clients in commercial arbitration and investor/state disputes across a variety of arbitral forums, especially (but not exclusively) where the substantive or procedural law of the arbitration agreement is English or that of another common law jurisdiction.

We represent high net worth individuals, companies, institutional corporations and sovereign states / state owned entities in international commercial arbitration conducted under the rules of all major arbitral institutions, including the LCIA, ICC, SCC, SIAC, HKIAC, AAA and LMAA. Additionally, we conduct ad hoc arbitrations.

We also regularly act in relation to separate arbitral challenges and/or in domestic proceedings concerning enforcement or jurisdiction issues arising from an arbitral award. We are experienced in enforcing arbitral awards across the world, whether under the New York Convention of through local procedures in other jurisdictions.

Our team members have conducted and advised on claims under bilateral investment treaties and other instruments for both investor claimants and for States.
