Sylvie is a Founding Partner of Signature Litigation’s Paris office. She specialises in product liability, toxic tort, ESG, and group litigation disputes.
With almost 20 years’ experience, Sylvie represents manufacturers doing business in France in complex product-related disputes, including product liability, industrial risk, product safety, toxic tort, mass litigation/class actions, regulatory compliance, and environment/climate change matters.
Sylvie represents a variety of globally recognised manufacturers from industries including automotive, electronics, life sciences, cosmetics, new technologies, steel, energy, food, toys, and consumer goods. She manages one of the largest product litigation teams in the French market.
She is involved in several high-profile French industrial disaster cases, including large-scale fires, planned obsolescence allegations, use of conflict minerals, ‘dieselgate’, maritime engine accidents, marketplace liability, and COVID-19 vaccine cases.
She defends clients against claims from consumers, NGOs, business partners, and competitors, and also handles investigations by French market surveillance authorities such as the DGCCRF, ANFR, and ANSM. She has also coordinated product safety corrective measures across the European Union.
Sylvie also assists her manufacturing clients with commercial litigation (e.g., sudden termination of contracts, unfair competition, significant imbalance cases) and the review of contracts and Terms & Conditions.
Sylvie is a leading defence counsel in France for manufacturers facing mass toxic tort claims and consumer group actions. Her work in this area began with asbestos-exposure claims, where she established rare, company-favourable case law. Some of these cases are cited in the French Civil and Social Security Codes due to the significant legal precedents they set. Her practice now includes cases involving various chemical and hazardous substances, as well as claims based on anxiety over developing future diseases.
Sylvie is a go-to lawyer for class actions in France. She has conducted a study for a client on class action systems in over one hundred jurisdictions and is one of the few defence counsel invited to participate in the Cambridge Forum’s working group on class actions in the EU.
Sylvie is highly recognised for her skills as a litigator by directories. She is described by Lexology Index as a “dynamic and determined litigator”, who is “a firm favourite among clients” as “she always goes the extra mile to support her clients, and is proactive in seeking commercial solutions to disputes.”
Sylvie has been ranked for a number of years as a ‘Thought Leader’ in the Lexology Index France: Product Liability Defence Guide, which notes her “rigorous analysis, strategic guidance and seasoned litigation” on complex product disputes and recognises her as a “a star in the international world.” She is also recognised as one of the ‘Global Elite Thought Leaders’ in Lexology Index’s Product Liability Defence Guide, which notes Sylvie “cuts a distinguished figure in the market for representing manufacturers in the automotive, energy and food industries.”
In The Legal 500 EMEA 2026, Sylvie is ranked as a ‘Leading Individual’ for her commercial litigation expertise, and she “stands out for her unparalleled expertise in product liability defence in France, as well as for her exceptional interpersonal skills.” She is also described as a “true expert in her field.” The 2025 Guide highlights her as “the North Star of product liability and compliance issues.” Past Guides have also identified her as a “leading toxic tort / mass litigation lawyer.” She is one of the only two lawyers ranked in the product liability category for France. Chambers France 2026 recognises Sylvie as “one of the best in her field” for Product Liability & Industrial Risk.
She has won several awards such as the “Best in Product Liability” award at the 2019 LMG Euromoney Europe Women in Business Law Awards and the Lexology Client Choice award in Product Liability in 2021, 2022, 2023 and 2024, with General Counsels stating about her that she “embodies the epitome of client service, seamlessly merging quality, value, and foresight. Her advice is not just legally sound but exhibits a profound understanding of our business goals and industry nuances.” Sylvie is also recognised for her expertise in commercial litigation by Lexology Index and Best Lawyers.
Prior to joining Signature Litigation, Sylvie practised for 11 years at the Paris and London offices of Hogan Lovells.
Sylvie is a member of the Board of Directors of the International Association of Defense Counsel (IADC) and is currently the only European member on its Board. Sylvie is also an active member of the International Consumer Product Health and Safety Organization (ICPHSO).
Sylvie is admitted as an Avocat à la Cour and a Solicitor in England and Wales. She is fluent in French and English.
