WWL Ranking: Future Leader

WWL says

Guillaume Tattevin is lauded as "a great lawyer" who possesses "excellent legal skills and commercial sense". ​


Guillaume Tattevin has practised arbitration since 2001 and still enjoys every moment of it. He is a partner of Archipel, a boutique international firm with offices in Geneva and Paris. Guillaume works in Geneva, where he has been based for 10 years and from where he handles arbitrations in Switzerland, Europe, the Middle East and Africa.

Guillaume acts mainly as counsel in commercial arbitration, in cases involving most typical international contracts, including sale, agency, joint ventures, distribution and construction. He provides clients with full service representation, including pre-arbitration assessment, advice in negotiation and mediation, and support on the worldwide enforcement of arbitral awards. He regularly acts as co-counsel with international firms and appreciates the opportunity to cooperate on arbitral cases. Guillaume also sits as an arbitrator.

He has worked in over 50 international arbitrations under the usual international institutional and ad hoc rules and a few less usual ones, mostly under Swiss, French and related laws, as well as under general principles of international commercial law.

Guillaume initially practised arbitration in Paris with Freshfields Bruckhaus Deringer, in The Hague as a legal counsel with the Permanent Court of Arbitration, and in Switzerland as an attorney with LALIVE. He studied law at Paris Nanterre University (1999) and Panthéon-Assas University (2001) and holds an LLM from the University of Essex (2000). He is a French national and is registered to practise in Switzerland and in France.

He is a member of the Swiss Arbitration Association, the ADR commission of the Geneva Bar Association and the Swiss Art Law Association.

Guillaume works in English and French and reads legal Spanish.
