Biography

Anaïs Harlé is Counsel in the International Arbitration Group in Paris, with more than a decade of experience representing States and multinational corporations in investment and commercial arbitrations conducted under leading institutional and ad hoc rules (ICSID, ICC, SCC, LCIA, UNCITRAL). She has been described as a "top-notch arbitration lawyer", and a "sharp, skillful and extremely professional" one who "integrates and uses the technical arguments of the dispute in the best possible way for her client" (Lexology Index, 2026).

Anaïs' practice centers on complex construction, infrastructure and energy disputes. She has advised and defended clients worldwide, including in Africa, Eastern Europe, and the Middle East. She has a strong interest in offshore and coastal projects, marine renewable energy and seabed governance. She has also worked on disputes in the mining, hospitality, aviation and M&A sectors, as well as on matters involving money laundering and corruption allegations. She frequently acts in arbitration-related proceedings before French courts, including annulment actions and applications for interim measures relating to first-demand guarantees under FIDIC contracts.

Anaïs is a Co-Chair of the French Arbitration Committee's under-40 group (CFA40), lectures in international arbitration and regularly speaks at arbitration conferences. She is listed on the rosters of arbitrators of the Dubai International Arbitration Center (DIAC) and the Paris International Arbitration Chamber (CAIP), and is a member of the CAIP working group tasked with preparing guidelines on arbitration and artificial intelligence.

She has also spent time in the Firm's New York office.
