OUR IDENTITY

Founded in 2023, the firm is the result of a partnership between lawyers Louis Jay, Marjorie Duquennoy and Arthur Gaulier.

As members of the Paris Bar, they have forged strong professional links, having previously practiced with renowned criminal lawyers.

They have pleaded numerous cases before all the criminal courts in France and its overseas departments, regions and communities.

They have acquired the values of a rigorous, demanding and combative defense.

The firm draws on this experience to offer a comprehensive range of preventive and criminal defense services to corporate and individual clients.
