Who's Who Legal Arbitration: Lawyers

Bart Legum is a partner in Dentons' Paris office and head of the firm's investment treaty arbitration practice. Bart has over 25 years' experience in litigating complex cases and has argued before numerous international arbitration tribunals, the International Court of Justice and a range of trial and appeals courts in the United States. His practice focuses on international arbitration and litigation in general and arbitration under investment treaties in particular.

From 2000 to 2004, Bart served as chief of the NAFTA arbitration division in the office of the legal adviser, United States Department of State. In that capacity, he acted as lead counsel for the United States government defending over US$2 billion in claims submitted to arbitration under the investment chapter of the North American Free Trade Agreement (NAFTA). The United States won every case decided under his tenure.

Bart is a past chair of the section of international law of the American Bar Association, an international bar organisation with over 24,000 members from over 90 countries around the world. In 2012–2013, he served as chair of the section and chaired its executive committee, council and administration committee. He served as an officer of the mediation committee of the International Bar Association from 2009 to 2012 and co-chaired the subcommittee that drafted the IBA Investor-State Mediation Rules.

He is the editor of International Litigation Strategies and Practice (2d ed 2014), a book published by the American Bar Association. He also is the editor of Investment Treaty Arbitration, an annual publication of Law Business Research. Bart is often published on international dispute resolution topics and frequently speaks at conferences on international arbitration and litigation.

Bart joined Salans (now Dentons) in 2009; before this he was at Debevoise & Plimpton LLP in their Paris (2004–2008) and New York (1987–1999) offices. Between 1986 and 1987 he was a law clerk for the Honorable Carolyn Dineen King at the United States Court of Appeals for the Fifth Circuit in Houston, Texas.

He studied at the University of Paris II – Panthéon Assas (DEA in public international law, 1987); the University of Georgia School of Law (JD, magna cum laude, 1985); and Rice University, BA (1982).

Bart speaks French and English. 

WWL says: Bart Legum is "absolutely excellent" and one of the premier investment treaty arbitration experts in France.
