Bersay, which brings together lawyers of various different nationalities, has successfully forged trusting relationships with law firms in other countries with which it works on a daily basis. 

These firms have been chosen for their expertise and reputation, but also for their adherence to a common set of fundamental values that Bersay has placed at its core and which are notably the values of responsiveness, efficiency, team spirit and pugnacity.
Thanks to its strong ties with these partner firms, Bersay is able to form integrated teams for each international assignment.

Bersay has set up several foreign desks composed of lawyers who interact with French or international clients, either on a day-to-day basis or in connection with complex projects, in several parts of the world.

Lawyers from Bersay Dispute Resolution teams specialize in resolving all manner of legal disputes that companies encounter in operating their businesses. Our experience in this domain covers all aspects of business law, corporate law and securities/stock market law, as well as intellectual property, IT, data protection, bankruptcy proceedings and white collar criminal law. The Firm has earned a first-rate reputation for its business litigation practice.

Lawyers in our arbitration practice are recognized for their skill in resolving international disputes through ad hoc or institutional arbitration, in particular before the ICC. Bersay intervenes upstream by drafting arbitration clauses, conducting procedures, including witnesses hearings, as for the exequatur and arbitration sentences rendered in France or worldwide.

The Firm has developed a practice in alternative disputes resolution methods, including conciliation and mediation. Convinced by the necessity to promote settlement agreements when appropriate, the lawyers from the Dispute Resolution Department often act as party’s counsel during mediations.

As companies must adapt to the constraints imposed notably by regulatory authorities, the firm effectively supports its clients with their regulatory and compliance challenges in their transactions or day-to-day operations. We help our clients to manage risk and understand their duties and liabilities.

As each dispute is unique, we strive to adapt our approach on a case by case basis to the specific real-life circumstances and to our client’s financial and strategic objectives or constraints. This is why we evaluate each situation with our client in order to develop a tailored solution.
