About Three Crowns

Founded by practice leaders with decades of experience in leading international firms, Three Crowns is recognised as “one of the premier arbitration practices in the world” and “the go-to firm for high-value and complex matters”.

With 80+ lawyers qualified in 30 jurisdictions and offices in London, Madrid, Paris, Singapore and Washington, DC, we offer clients a seamless service and experienced practitioners on every mandate.

We have represented many of the world’s leading corporations, in addition to States and State-owned entities. Clients seek our advice on their most significant disputes, including those with novel legal issues and issues that are commercially important to their operations.

Our partners are leaders in the field of arbitration. They are consistently top-ranked by clients and regularly elected to institutions and rule-setting bodies.

Our associates also boast deep expertise in international arbitration. This expertise is gained in practice and through focused post-graduate study, clerkships with international courts and tribunals, and experience in the leading international arbitration institutions.

Three Crowns lawyers have authored important books and articles on arbitration and public international law, and speak regularly on these topics. Members of our team teach at universities including Columbia Law School, the Geneva Center for International Dispute Settlement, Harvard University, the London School of Economics, and Sciences Po.

As part of our premium service, we conduct our own advocacy. This approach is born of the conviction that, as the lawyers with day-to-day conduct of a case, we are best placed to present that case to a tribunal. Our partners – including several King’s Counsel – are expert advocates with decades of experience. Conducting our own advocacy also reduces costs by eliminating the need for barristers or other specialist counsel.
