Three Crowns LLP is a specialist international arbitration firm representing multinational corporations and sovereign states in complex commercial, investor-state, and public international law disputes.
Three Crowns LLP is a specialist international arbitration firm, founded in 2014, that handles complex international disputes for multinational corporations and sovereign states. It is not a full-service shop: the practice is deliberately narrow, built on the premise that the quality of advice and advocacy - not billed hours - decides outcomes in high-stakes cross-border disputes. The firm fields over 180 professionals, including 19 partners, with lawyers qualified in more than 30 jurisdictions and working across more than 35 languages. Offices are in London, Paris, Washington, DC, Singapore, and Madrid.
The work spans commercial arbitration, investor-state arbitration, public international law, and arbitration-related litigation. Recent landmark results include a $8.5 billion ICSID award, a $2 billion ICC award, and a $2.5 billion ad hoc award. On the litigation side the firm has appeared before the US and UK Supreme Courts and the Paris Court of Appeal in proceedings connected to arbitration. Chambers & Partners ranks the practice Band 1; Legal 500 places it Tier 1.
Internally, the operating model is focused rather than volumetric: six founding partners set out to build a practice dedicated to international disputes, and the team is assembled around advocacy and jurisdictional depth rather than generalist coverage. That concentration shows up in the qualification mix and language coverage across the five offices, and in a docket that runs from energy and natural resources matters to sovereign and public-sector representation.
