Restitution and provenance: the dealer's duty of vigilance

01The legal framework of provenance

In France, the dealer's duty of diligence regarding provenance is governed by several texts. The Heritage Code (Articles L111-1 et seq.) imposes an obligation of vigilance in the trade of cultural property. The 1970 UNESCO Convention, ratified by France, prohibits the illicit transfer of ownership of cultural property. EU Directive 2014/60/EU on the return of cultural objects unlawfully removed from the territory of a Member State reinforces this framework.

EU Regulation 2019/880 on the import of cultural goods, coming into force progressively, imposes new documentary obligations for cultural property imported from third countries. This regulation particularly concerns antiquities and archaeological objects, but it establishes a regulatory precedent that could extend to other categories of cultural property.

Beyond these texts, the Civil Code and the Penal Code punish receiving and complicity in receiving stolen goods, including when the buyer is unaware of the illicit origin but should have suspected it by exercising reasonable diligence. A dealer who sells a work with a lacunary provenance faces prosecution if the work proves to have been stolen or looted.

02Second World War spoliation

The spoliation of Jewish property during the Occupation constitutes the most painful chapter in provenance history. The Mattéoli Mission, created in 1997, estimated that tens of thousands of artworks were confiscated in France between 1940 and 1944. The Commission for the Compensation of Victims of Spoliation (CIVS), created in 1999, continues to process restitution claims.

The MNR (Musees Nationaux Recuperation) constitute a holding of approximately two thousand works recovered in Germany after the war and entrusted to national museums pending restitution to their legitimate owners or their heirs. The Louvre, the Musee d'Orsay and the Centre Pompidou hold MNR works that are the subject of active research to identify their owners.

For the dealer, vigilance primarily concerns works created before 1945 whose provenance shows a gap between 1933 and 1945. The Art Loss Register, an international database of stolen and looted works, offers a verification service that every prudent dealer should use before accepting a work from this period. The 1998 Washington Principles, adopted by forty-four countries, commit signatories to search for looted works and facilitate their restitution.

03Colonial heritage and repatriation demands

The Sarr-Savoy report, commissioned by the French president and submitted in November 2018, propelled the question of colonial heritage restitution to the centre of public debate. The authors recommended the restitution of works acquired by force or under conditions of manifest inequality during the colonial period. The law of 24 December 2020 authorised the restitution to the Republic of Benin and Senegal of twenty-seven works, marking a historic legislative precedent.

For the contemporary art dealer, this question is less directly relevant to daily practice but it influences the general context in which they operate. Collectors are increasingly sensitive to provenance ethics, and a dealer who cannot attest to the legal origin of offered works loses credibility with an informed clientele.

Non-European art objects, antique textiles, artefacts and ethnographic photographs are the categories most concerned by these debates. A dealer trading in such works must document their provenance with particular rigour and be able to demonstrate they were legitimately acquired.

04Reasonable diligence in practice

Reasonable diligence (due diligence) is the standard of conduct expected of the dealer regarding provenance. It involves several concrete steps.

The first is verifying the seller's identity. The dealer must know from whom they are buying and ensure the seller is the legitimate owner of the work or their authorised agent. Identification, proof of address and, where possible, proof of ownership (purchase invoice, auction certificate, inheritance attestation) should be obtained and retained.

The second step is reconstructing the chain of ownership. For works predating 1945, this reconstruction must be as complete as possible, with particular attention to the period 1933-1945. For contemporary works, an invoice from the originating gallery or a certificate of authenticity issued by the artist or their catalogue raisonne generally suffices.

The third step is consulting specialised databases. The Art Loss Register, the INTERPOL register of stolen works, the French Ministry of Culture's database of looted cultural property and the Joconde portal for French public collections are tools the dealer must know and use.

The Helly Nahmad Gallery in New York was involved in a restitution case concerning a Modigliani stolen during the Occupation, which resulted in 2017 in the work's return to the heirs of its legitimate owner. This case illustrated the concrete risks facing galleries that neglect provenance verification.

05The provenance certificate: a trust-building tool

The provenance certificate is a document tracing the ownership history of a work. It is not legally required for all transactions in French law, but it constitutes professional best practice that protects the dealer and reassures the collector.

The certificate should mention the artist's identity, the work's title and description, its dimensions and medium, and the list of successive owners as far back as documentation allows. Gaps should be honestly flagged rather than concealed: a collector who discovers after purchase that provenance is incomplete loses confidence in the dealer.

Auction houses such as Christie's and Sotheby's systematically publish provenance in their catalogues, and collectors accustomed to these standards expect the same level of transparency from galleries. A dealer who spontaneously provides a detailed provenance certificate distinguishes themselves favourably from one who does so only on request.

06Training the team in vigilance

Provenance diligence cannot rest on the dealer alone. Staff who receive works on consignment, welcome potential sellers or prepare sales dossiers must be trained in verification reflexes. A systematic checklist — seller identity, documented provenance, Art Loss Register consultation — standardises verifications without burdening processes.

The CPGA (Comite professionnel des galeries d'art) offers training and resources on these subjects. Major auction houses also organise awareness sessions open to market professionals. A dealer who invests in team training reduces risk exposure and strengthens client confidence.

For galleries on Artedusa, rigour in provenance matters is a mark of seriousness that international collectors, accustomed to Anglo-Saxon due diligence standards, particularly appreciate. Mentioning a provenance policy in the gallery's presentation on the platform signals a professionalism that inspires trust.
