How the ranking was prepared
The selection has been prepared through an independent editorial analysis and an overall assessment of the career, specialisation, experience and professional recognition of the lawyers included. Multiple sources of information have been taken into account, including the websites of the professionals themselves and their firms, news and publications appearing in the media, matters and transactions in which they have been involved, their academic and institutional activity, their national and international profile, and references within the legal and business community.
Particular attention has also been paid to the perception of clients and professionals familiar with their work, assessing factors such as the trust they inspire, responsiveness, legal judgement, effectiveness in resolving matters and the recognition achieved within their respective areas of specialisation. The result reflects a combined editorial assessment of objective and qualitative factors, designed to capture not only career track record and technical knowledge, but also the prestige and professional standing each lawyer has consolidated through legal practice.
How to interpret the selection
The ranking is an editorial snapshot of the legal market in Switzerland based on information available in 2026. It does not measure fees, guarantee outcomes or claim that any included professional is the right choice for every matter.
