The seizure of an artwork, antiquity, coin or collectible by French Customs is often the beginning rather than the end of the legal process. The next steps depend on the suspected offence, the status of the object and the investigative measures undertaken by the authorities.

The investigation may continue after the initial control

Customs officers may seek additional information about the object, its origin, acquisition, importation or intended export. They may examine documents and obtain specialist input concerning whether the object falls within the legal regime for cultural property.

In some cases, the investigation may involve interviews, customs detention or further investigative measures. The 2 April 2025 French Supreme Court case concerning ancient coins illustrates how an initial vehicle control can develop into a broader investigation.

The procedure must be reviewed as a whole

Several distinct questions can arise after a seizure: the legal basis for retaining the object, its classification as cultural property, the provenance evidence available, the legality of coercive measures and the offences ultimately alleged.

These questions should not be confused. A weakness in provenance documentation does not, by itself, answer every question concerning the legal classification of the object or the validity of the procedure.

Possible criminal proceedings

Depending on the case, a customs investigation may result in no further action, a customs resolution or proceedings before a French criminal court. Where proceedings continue, the defence may need to address both the substance of the alleged customs offence and procedural issues arising during the control and investigation.

For a foreign collector, dealer or company, early coordination with French counsel can also be important where documents, witnesses or acquisition history are located in another jurisdiction.

Preparing the response

The immediate priority is generally to preserve and organise the relevant documentation: invoices, acquisition records, export or import documents, collection inventories, correspondence, transport records and any other material capable of explaining the history and movement of the object. The relevance of each document will depend on the legal issues in the particular case.
