About id est avocats

"id est" is a Latin expression meaning "that is to say" (i.e. in abbreviated form). Clients expect nowadays from their legal counsel far more than a perfect knowledge of the law. Trusted attorneys shall be able to assist in ambitious projects and help design and implement complex negotiation or litigation strategies; they must fit in multidisciplinary teams, explain the stakes, and formulate no non-sense, pragmatic and actionable advice to diverse stakeholders: board of directors, entrepreneurs, shareholders, investors.

In line with our philosophy, we focus on certain industries of which we know the rules, the players, the specificities, the market standards and the best practices: computing, advanced technologies, media and advertising, commercial and corporate, and intellectual property, especially in the field of software and online services.



Our work has been highly recommended by the market and leading guides such as Chambers Global, Chambers Europe, Legal500 and Who's Who Legal. We were also voted Swiss Boutique Law Firm of the Year by industry experts in 2012 and 2013, and Law Firm of the Year in ‘Technology’ (Corporate Int’l Awards), ‘Corporate Finance and M&A’ (M&A Int’l) and ‘Media’ (ACQ Law Global Awards).

"The firm always adds strong value by understanding the business issues and translating them into solid legal terms." (Chambers Europe 2014)

"The lawyers are hands-on, able to grasp complex concepts and strong in negotiations" (Chambers Europe 2015)
