Where provenance meets strategy

Dr. Margaux Dumas is an independent strategic counsel specialising in Nazi-era provenance research, restitution, and art market compliance. Holding a PhD from Université Paris-Cité and Technische Universität Berlin (summa cum laude, 2022) and an MA from the Courtauld Institute of Art, London, she advises auction houses, collectors, insurers, and legal firms across Europe, the United States, and the Middle East, from complex due diligence and AML compliance to expert witness testimony in international proceedings. She is based in Paris and is available globally.

Dr. Margaux Dumas brings together deep archival expertise and strategic advisory at the intersection of art history, law, and market compliance. Her work covers the full spectrum of provenance risk: Nazi-era spoliation and restitution, illicit trade, post-Soviet displacement, sanctions exposure, and the evolving regulatory landscape for the art market under EU, UK, and US frameworks.

She has conducted provenance research and strategic advisory for families dispossessed during the Second World War, major auction houses, private collectors, and public institutions in France and abroad. In 2023, she served as expert to the Formation interchambre on restitution, chaired by Gilles Andréani (Cour des Comptes). She is currently a Saul Kagan Fellow in Advanced Shoah Studies with the Claims Conference (CNRS).

She holds a PhD from Université Paris-Cité and Technische Universität Berlin (summa cum laude, 2022) and an MA from the Courtauld Institute of Art, London (2016).

Trained at Sciences Po Toulouse, the Courtauld Institute of Art, and across the archives of France, Germany, and beyond, Dr. Margaux Dumas brings an interdisciplinary lens that is rare in the field. She combines the rigour of academic history with the pragmatism required in commercial and legal contexts. She works in French, English, and German, and conducts research across European, American, and Israeli archives. Her practice spans the full chain from initial risk assessment to litigation support, advising clients who need not just research, but judgment. Where mandates require it, she works alongside a trusted network of art lawyers, legal counsel, and specialist advisors to provide comprehensive, end-to-end support.

Nazi-Era Provenance Research

Comprehensive research on ownership histories for works at risk of Nazi-era spoliation: gaps, inconsistencies, the 1933–1945 period, contested transfers. Assessment of contextual authenticity where documentary evidence is incomplete, ambiguous, or disputed. Research extends to paintings, furnishings, objects, and cultural property beyond the canonical categories. Litigation-ready documentation.

Illicit Trade & Illegitimate Circulation

Investigative research on works with suspected links to illicit trade, sanctions regimes, or illegitimate circulation, including post-Soviet displacement, trafficking of cultural property, and contemporary conflict contexts.

Regulatory Compliance & AML

Advisory on anti-money laundering obligations and import/export compliance under EU Regulation 2019/880, UK, and US frameworks. Compliance audits, internal policy development, and staff training for auction houses, dealers, and institutions operating in the art market.

Expert Witness & Litigation Support

Independent expert opinions and testimony for international arbitration, civil proceedings, and regulatory investigations involving artworks and cultural property.

Authentication & Contextual Authenticity

Provenance research as a tool for authentication: investigating ownership histories where questions of attribution, authorship, or genuineness are at stake. Assessment of contextual authenticity when physical or documentary evidence is incomplete, disputed, or contested. Expert analysis for collectors, institutions, and legal proceedings where provenance and attribution intersect.

Risk Analysis & Due Diligence

Pre-acquisition, pre-sale, and pre-loan due diligence for collectors, institutions, auction houses, and insurers. Risk mapping, database screening, and strategic counsel on provenance exposure before it becomes liability.
