LOONIS QUÉLEN
Law Office
Attorney
The LOONIS QUÉLEN Law Office was founded to provide rigorous, independent, and cross-border legal support. The practice focuses primarily on maritime law, as well as civil and commercial law.
Strategically located between Paris and Geneva – two internationally influential cities – the Office benefits from a privileged position at the crossroads of legal, economic, and institutional exchanges. This dual presence enables smooth legal practice between France and Switzerland, while maintaining strong ties with transnational environments – particularly in Geneva, within the framework of international cooperation.
The Office offers a flexible and responsive professional structure, tailored to technical, international, and sensitive legal issues. Its organization is grounded in demanding legal standards and a deep understanding of the operational realities of the sectors involved.
The practice is structured around four complementary services:
The Office acts before civil and commercial courts, contributes to the work of professional associations, and provides training and academic input.
This website offers an overview of the areas of practice and professional engagements, provides updates on the Office’s activities, and facilitates direct contact.
