Swiss services

Our services are governed
for Swiss professional secrecy


We refer to confidentiality in the communications established between the lawyer and his clients. This privacy extends to all the information that the consultant receives from the client.

Swiss law provides for strong protection of confidentiality, because constitutional law in Switzerland places a high value on the protection of privacy. (Federal Constitution of the Swiss Confederation April 18, 1999 RS 101, article 13).

EThe Swiss High Court of Justice has emphasized professional secrecy with the intention of ensuring that clients of legal and financial services will be able to fully trust a Swiss lawyer.

Also, if the client does not trust their attorney then it will be difficult, or even impossible, for the attorney to be able to represent the client, either in counseling work or in a lawsuit. (BGE 112 Ib 606, 606-7).
