Your attorney

I'm Stefan Lenz, lawyer LL.M. As a self-employed lawyer and former federal prosecutor, I work in the field of white-collar crime; as former prosecutor, I specialized in combatting multinational corruption.

Lawyer and former federal prosecutor

From 2002 to 2016, I was a federal prosecutor at the Swiss Office of the Attorney General leading extensive and complex criminal investigations in the field of international corruption.

My expertise is in the field of white-collar criminal law and the multinational criminal law cooperation.

I offer my knowledge and expertise to all the defendants in white-collar crime cases or victims and injured parties of such crimes who depend on legal support in Switzerland.

Special area of expertise: white-collar crime/corruption

After my studies in law at University of Bern, I specialized in international economic law first with post-graduate studies in "International Economic Law" and subsequent in-depth post-graduate studies MAS ECI, "Economic Crime Investigation."

In 2002 I started working for the Swiss Office of the Attorney General in the white-collar crime department. I specialized in the area of international corruption and money laundering, among other positions as deputy director of the then called Division Economic Crime II (EC II).

As a federal prosecutor I continually took part in professional development events, some of them organized by the World Bank.

Alstom, Gaddafi, Petrobras, Odebrecht

In cooperation with other federal prosecutors and with the support of members of the Federal Criminal Police, I headed complex, multinational corruption and money laundering procedures; among others, the successfully finalized procedures against Alstom, a member of the Gaddafi family as well as numerous investigations in connection with the Petrobras/Odebrecht scandal in Brazil.

International network

As a federal prosecutor, I have been in a position to network and establish contacts with leading prosecutors from all over the world, especially in Europe, the U.S., South and Central America.

Further valuable relations are those to important representatives of investigative agencies of the World Bank and the European Development Bank.
