Thibault Guillemin is a preferred contact of corporations, institutions and their representatives facing complex issues or reputational risks. He advises as well as litigates on crisis situations entailing simultaneous regulatory, ethical, criminal and social aspects.

Beyond his counseling activities, Thibault is a next generation litigator who defends companies and their managers facing internal investigations and/or enforcements.  He represents for many years several companies and individuals in high-profile cases.

Prior joining the Paris Bar, Thibault practised as a counsel in a French law firm of supreme court attorneys (avocats au Conseil d’Etat et à la Cour de cassation) where he managed many cases involving government bodies.

Furthermore, he advises listed or non-listed companies in setting up, evaluating and strengthening their compliance programs (codes of conduct, internal audit, risk analysis, KYC, professional alerts, training), both with regard to French legislation (Sapin II, Devoir de vigilance) and foreign ones (FCPA, UKBA).

His practise focuses as well on economic sanctions (embargoes, export controls) and export controls that French and European companies may face (sanctions programs, extraterritoriality, blocking statutes, dual-use items, etc.).

Thibault Guillemin's team has been recognized as "Excellent" for its white collar practise by Leaders League 2023, and appointed as "Rising Team 2020" for his Compliance expertise by the Trophées du Droit, a panel of French high-level professionals awarding the best lawyers for their practise.
