Dispute Resolution

With recognized expertise in civil and criminal litigation, our Litigation and Arbitration department handles all types of civil, commercial, financial, and criminal disputes. We also handle domestic and international arbitration matters. 

We support our clients in complex and strategic cases at every stage of the litigation process: from the pre-litigation phase through enforcement proceedings, including representing their interests in both trial and appellate courts. 

We assist you in all types of litigation, including contract law, commercial law, corporate law, liability disputes in all forms, financial law, construction law, healthcare law, environmental law, insurance law ( ), civil enforcement proceedings, business criminal law, tax criminal law, media law, and family law. 

Our team has expertise in the rules of the major arbitration institutions (ICC, LCIA, ICSID, etc.) and in ad hoc proceedings (UNCITRAL). We advise individuals, businesses, sovereign states, and public entities in complex international commercial arbitration proceedings and in investor-state dispute settlement (ISDS). We advise clients across a wide range of industries, handling disputes both in France and internationally. 

With extensive experience in dispute resolution, we support you at every stage of the dispute: 

• risk analysis; 
• pre-litigation handling; 
• development of a litigation strategy; 
• emergency or preventive proceedings; 
• representation before state courts and arbitration tribunals; 
• amicable resolution; 
• enforcement of court judgments and arbitral awards. 

We work closely with all of the firm’s teams, as well as with all of our international partners, to ensure you benefit from optimal technical expertise in every area of domestic and foreign law.
