Our Background

Because Fiducial Legal By Lamy has been present in the legal arena for over 50 years, devising solutions and creating added value for businesses, its entrepreneurial momentum has ensured it withstands the test of time.

When the firm’s founding member, Bruno Lamy, set up practice in 1965 following graduation, his immediate goal was to give impetus to the firm’s development by preempting the reform of the legal profession and merging the professional expertise of legal advisors and attorneys. The dual expertise provided by these practitioners has been the mainstay of Fiducial Legal By Lamy reputation and renown throughout the years.

Fiducial Legal By Lamy has always been geared to the future. In the mid-1980s the firm hired a new generation of partners with an international outlook, which led the firm to join the international legal network of TERRALEX and act as the network’s primary representative in France.

Backed by this experience, today’s third generation of partners continues to innovate and provide bespoke solutions to companies seeking to optimize their flexibility in a business environment marked by the digital revolution.


To meet your needs, act in the digital environment and provide high quality service, Fiducial Legal By Lamy draws on the relevant expertise of its various support teams, comprising more than 30 people.

Fiducial Legal By Lamy is at the cutting edge of the law and legal innovation is its driving force. It has made significant investment in a documentations service resourcing the full set of legal works cited, more than 130 specialist or non-specialist reviews within all core practice areas and avails of practically the full set of legal databases available online.

They also have a second office located in Paris: 13 boulevard Bourdon 75004 Paris.
