Dispute Resolution Lawyers

Our Dispute Resolution team has three partners, Jean-Fabrice Brun, Olivier Kuhn and Francois-Xavier Mattéoli, and a team of seven employees dedicated entirely to the work.
With extensive experience in civil and criminal proceedings, we work in all types of civil, commercial, financial and criminal litigation. We also work in domestic and international arbitration.
We support our clients in complex and strategic cases at every stage of litigation: from the pre-litigation phase to enforcement measures to representing their interests at first instance and on appeal.

We can assist you in all types of litigation, including contract law, commercial law, corporate law, litigation concerning any form of liability, financial law, construction law, healthcare law, environmental law, insurance law, civil enforcement procedures, criminal business law, criminal tax law, media law and family law.
With extensive experience in dispute resolution, we can support you at every stage of litigation:

  • risk analysis;
  • pre-litigation process;
  • defining a legal strategy;
  • emergency or preventive procedures;
  • representation before national courts and arbitral tribunals;
  • amicable settlement;
  • enforcement of court decisions and arbitral awards.

Working closely with all the firm's teams and all our international partners, we can provide you with optimum technical expertise in all areas of domestic law and foreign law.
Available at any time, we can be mobilised in an emergency, for example to assist you in criminal or tax searches.
