  Erwan Poisson

Partner

Paris

Erwan is a Partner in the Litigation department at Allen & Overy Paris. He advises international and domestic companies in complex commercial, civil, and criminal disputes, from the prelitigation stages of a matter, including alternative dispute resolution methods, to Court trials. He also covers representations before the courts of French-speaking African countries in commercial and criminal litigation matters, as well as before international courts (in particular, the ILO Administrative Tribunal).

A general litigator, Erwan notably advises in the areas of banking and finance litigation, where his experience includes liability claims against banks, financial services and investment funds; corporate litigation, including disputes between majority and minority shareholders, disputes related to shareholding agreements as well as representations and warranties.

He has also developed specific expertise in conflicts of laws and jurisdictional issues (a subject he teaches at university), international judicial assistance, asset-tracing and recovery, and the enforcement of foreign judgments and arbitral awards on assets located in France.

Erwan also handles contractual and distribution disputes as well as product liability matters and insurance disputes, with a focus on the aviation sector.

Erwan has worked in France and in the UK and he is qualified in both jurisdictions.
