International Arbitration — Our Services
International Arbitration
We are experienced handling multi-jurisdictional cases that involve acting for clients in large-scale arbitrations, governed under various arbitration rules and ad hoc commercial arbitrations.

Our arbitration practice is complemented by our litigation capabilities, including obtaining interim relief from courts in support of arbitrations, enforcement of arbitral awards and asset recovery.

We act as counsel in domestic and international commercial arbitrations, both ad hoc arbitrations and arbitrations under various institutional rules such as those of the London Court of International Arbitration (LCIA), the International Chamber of Commerce (ICC), the Stockholm Chamber of Commerce (SCC), the Swiss Chambers’ Arbitration Association, the London Maritime Arbitrators Association (LMAA), the American Arbitration Association (AAA) and the Singapore International Arbitration Centre (SIAC).

We also advise on the drafting of arbitration clauses where expert arbitration advice is sought, and on designing case strategy involving parallel proceedings.
