Three Crowns is proud to celebrate its 10th anniversary, marking a decade of recognised excellence in the practice of international arbitration and international law.

Founded in April 2014 by six leading practitioners, Three Crowns now counts 18 partners and a total of nearly 100 lawyers, qualified in over 30 jurisdictions. Following its simultaneous office openings in London, Paris, and Washington, DC upon launch, the firm has expanded into Singapore (2022) and Madrid (2023).

Three Crowns remains committed to its founding belief that international disputes require relentless focus in advice and advocacy alike, delivered by lean teams with hands-on partner involvement from beginning to end. In its first decade, the firm has acted for leading multinational corporations and sovereigns on their most complex international disputes, including those arising in commercial arbitration, investor-state arbitration, public international law, and arbitration-related litigation.

The firm is consistently recognised as an industry leader in international rankings and directories.  Recognitions include its placement as both a Band 1 firm in Chambers & Partners and a Tier 1 firm in Legal 500, as well as a top five firm in Global Arbitration Review’s (GAR) ranking of the world’s leading international arbitration practice groups. Three Crowns’ successes during its first decade are notable, and include a historic $8.5 billion ICSID award, a $2 billion ICC award, and a $2.5 billion ad hoc award. The firm has also appeared before the US and UK Supreme Courts, as well as the Paris Court of Appeal, and is increasingly taking on select court proceedings relating to arbitration.

Georgios Petrochilos KC, the firm’s executive partner and a co-founder of the firm, said: “We are delighted to celebrate our first decade of practice, and immensely proud to be recognised for excellence in cases of importance to our clients and to the development of the law.  In celebrating this special milestone, we are most grateful to our clients for entrusting us with their most important and complex disputes, and to our team for their continuing commitment to the firm’s founding values.  These core values will lead us through our second decade and beyond.”
