Philip Devenish dedicates his practice to resolving the most challenging, complex, and high-value international disputes. Over the past eight years, he has won or settled 100 percent of his cases.

Philip has secured billions of dollars for global corporations and financial institutions in some of the largest cross-border disputes of the past decade, as ranked by The American Lawyer and Global Arbitration Review. His landmark victories include a US$1.1 billion damages award against Russia for the expropriation of banking investments in Crimea. On the defense side, he successfully settled a US$2 billion dispute for Saudi Arabia on a drop-hands basis during the Qatar diplomatic crisis.

Philip has conducted arbitrations under every major institution (including the ICC, LCIA, HKIAC, SIAC, SCC, DIAC, AAA, and ICSID) spanning all the leading global arbitration hubs (London, Paris, Singapore, Hong Kong, Geneva, Zurich, The Hague, Stockholm, Dubai, New York, and Washington D.C.). He also handles multijurisdictional litigation, with a focus on major fraud, asset tracing, and enforcement.

He is listed in The Legal 500 UK's Arbitration Powerlist of lawyers who are "deemed the gold standard by businesses" and is ranked as the top arbitration lawyer in the UAE by The Arbitrators. Legal directories describe him as an "exceptionally talented professional" (Chambers UK) who is "widely praised by peers and clients" (Expert Guides) and has "practiced at the very top for many years" (The Legal 500 UK).
