We advise on all aspects of the arbitral process, from strategic considerations prior to the commencement of proceedings, through to the enforcement of a final award.


Our International Arbitration Group is made up of specialist arbitration practitioners with decades of experience acting as counsel on major international arbitrations, and advising multinationals, banks and governments on arbitrations seated in all the main arbitral centres, including London, Paris, Stockholm and Vienna. Our Singapore office also exclusively focuses on international arbitration.

Our services include providing specialist advice on:

  • Drafting arbitration agreements
  • Preparation of proceedings
  • Selection and appointment of arbitrators
  • Preparation of written arbitral submissions and advocacy at the hearing
  • Enforcement of arbitral awards
  • Ancillary proceedings in the High Court in London in support of international arbitration proceedings, such as bringing or defending applications for anti-suit injunctive relief in support of arbitration

We have experience of arbitrating under all of the principal arbitral rules, including those of the American Arbitration Association, International Chamber of Commerce (ICC), London Court of International Arbitration, Stockholm Chamber of Commerce, United Nations Commission on International Trade Law and Judicial Arbitration and Mediation Service; as well as industry-specific bodies and regulation, such as the Independent Film & Television Alliance, London Maritime Arbitrators Association and Rail Industry Dispute Resolution Rules.

Whatever the seat, arbitral rules and subject matter, our teams have the specialist expertise to guide you through the arbitration process and secure a successful outcome.
