Chammas & Marcheteau strengthens private wealth tax expertise with Sophie Mouthon
"Chammas & Marcheteau welcomes Sophie Mouthon to its tax department to bolster its private wealth tax practice; she will advise on domestic and international wealth matters alongside members of her team."
Sophie Mouthon advises corporate and individual clients on private and professional wealth matters, both domestically and internationally, in advisory and litigation contexts. She joins Chammas & Marcheteau as an associate. After nearly 25 years at the Anglo‑Saxon firm Latham & Watkins, Sophie Mouthon joined CFM Avocats in 2020, where she directed the tax practice.
Marine and Aurore join Chammas & Marcheteau as members of Sophie Mouthon’s incoming team.
Denis Marcheteau, co‑founding partner, said the arrival of Sophie, Marine and Aurore is part of a strong development dynamic for the firm and meets growing client demand from shareholders, business leaders and family offices. Christophe Moreau, partner in the tax group, noted that Sophie’s recognised experience and her in‑depth practice in private wealth taxation complement the firm’s activity and that her personal qualities align with the firm’s values.
