Profile of the Firm

L'Etude was created by the merger of the law firms of de Weck & Gillon and Hayoz & Perritaz, then, in 1998, with the Overney firm and, in 2011, with the Favre firm. With its origin dating back to the 1950s, L'Etude is well anchored in the judicial, economic and political realms of Switzerland.

Philosophy - Sharing of knowledge

L'Etude is organised in the form of a partnership company combining lawyers who offer clients their knowledge, experience, availability, and command of French, German, English, Spanish, Portuguese, Dutch, Swedish and Turkish. It is thus through the lawyer in charge of the matter that L’Etude provides advice and service based on the expertise of a whole team, not only in its areas of specialization but also in more general matters of law.


In our fields of specialization, our services are solicited by a private clientele as well as from important economic actors such as local governments, mid- to large-sized companies, insurance companies and construction companies.
