International Arbitration

Allen & Overy’s International Arbitration group advises a diverse range of corporates, financial institutions and governments on complex cross-border commercial arbitrations and investment treaty arbitrations.

With arbitration experts, including leading advocates, spread across our global network of offices, we advise on the most pressing and complex disputes wherever they arise. 

A&O’s international arbitration expertise spans the full range of sectors in which arbitration is used, including: 

  • Energy and natural resources
  • Construction and infrastructure projects
  • Telecommunications
  • Life sciences
  • Banking and finance
  • Intellectual property rights
  • M&A and joint ventures

Representing clients in arbitrations under all the key rules, including the ICC, LCIA, HKIAC, SIAC and UNCITRAL Rules, our specialist practitioners around the world are qualified in many jurisdictions and fluent in numerous languages. Senior members of our team regularly sit as arbitrators and hold key positions with the leading arbitral institutions and/or legal associations. Our experience allows us to most effectively represent our clients' best commercial interests.

We typically conduct our own advocacy in clients’ arbitration cases, delivering cost savings and ensuring our advocates are involved from the very start of proceedings. Our approach to the conduct of matters is always informed by our advocacy experience.
