International Arbitration

1 specialist practice area in International Arbitration

International businesses are increasingly turning to arbitration as a confidential, flexible and effective means of resolving their complex cross-border disputes. In sectors such as energy, banking and finance, engineering, life sciences and insurance, it is of paramount importance that your dispute is handled (and resolved) by those with expertise in the sector. International arbitration allows for just that.

Consistently ranked in the global directories of the world’s leading international arbitration practices, our team has a significant track record in international arbitration, from advising on the drafting of arbitration agreements through the conduct of the arbitral process to enforcing arbitration awards, including acting in related Court proceedings. We regularly act in arbitrations conducted under all the major rules (LCIA, ICC, HKIAC, SIAC, CIETAC, LMAA, UNCITRAL, AAA) and frequently act as advocates. Members of our team also sit as arbitrators. We work on a cross border basis and the international reach of our international arbitration practice means that we can field specialists in jurisdictions across the globe, working in a number of different languages. The CMS Guide to International Arbitration provides an overview or arbitration law and practice in 48 jurisdictions.

Our international arbitration team also has significant experience and expertise in investor state dispute settlement processes, focussing on the conduct of arbitration cases before specialist tribunals and advising on investment protection strategies.
