The Firm

The firm brings together three personalities with varied backgrounds and experience sharing a single aim: to advocate for their clients’ projects and interests through a rigorous approach to the law.

The members of the team are legal professionals who truly love their work and are guided by the wish to provide a service tailored to meet or even exceed each client’s expectations. The team’s first priority is to listen to its clients and build a relationship of trust, making way for an ambitious strategic approach to their projects and disputes. To achieve this, the firm’s staff all work together with the benefit of a strong involvement of the partners who constantly marshal their expertise and experience at the highest level. Along with rigor and ethics, creativity, obstinacy and attention to detail are fundamental qualities in the eyes of the firm.


Our lawyers are driven by team spirit and share the common imperative of respect, dignity, conscience, independence, probity, loyalty, solidarity, non-discrimination and humanity.

The firm’s know-how focuses on the international, strategic and complex issues that its clients may have to face, both in the field of litigation and in risk management.

Thanks to their respective experiences, the partners have established privileged relations with some of the leading firms the world over. These ties, which often stem from years of cooperation on complex and sensitive cases, are based on mutual respect and trust. We can thus support and advise our clients for all types of projects whether in France or abroad.
