Barthélemy Cousin

Barthélemy Cousin is a partner in charge of the Litigation and Insurance department at the K&L Gates Paris office.

Commercial Litigation practitioner Barthélemy has been assisting and advising numerous French and foreign companies in the insurance and reinsurance coverage litigation sector for over 25 years. He has always worked in the largest international firms.

For fifteen years now, he has resolutely chosen to position himself in the defense of the interests of policyholders against insurers or in the defense of the interests of reinsurers against insurers.

Barthélemy is also a member of AMRAE and AIDA. Barthélemy has also been a member of the Paris Bar since 1992.

Barthélemy has always paid particular attention to teamwork, particularly in the context of joint mandates with other law firms, or joint strategies coordinated with the advice of other parties. The international dimension of his practice has also frequently led Barthélemy to work with local correspondents, both in the United States and in French-speaking Africa.

Prior to joining the firm, Barthélemy served as a partner at a global law firm where he created and led its renowned insurance coverage and reinsurance litigation practice.
Previously, Barthélemy was a partner at an international law firm where he developed a recognized practice in insurance law litigation. There, he advised on international commercial disputes, particularly on insurance, energy, and transportation matters.
