Restitution agreements organize the return of a cultural property to its State of origin when it has been stolen, looted or illicitly exported. To date, 847 works have been returned through these arrangements.

Restitution relies on the reference conventions and on the work of focal points. It is linked with joint operations.

Establishing the Evidence

Every restitution begins with establishing the facts: identity of the property, place and date of removal, successive owners. The Organization's accredited experts analyse documents, photographs and excavation reports.

An OIMAP passport, where one exists, greatly facilitates this proof by preserving the history of the work.

The Role of the Parties

The requesting State submits the request and provides the evidence. The requested State verifies, seizes the property if necessary and organizes the handover. Each State's focal point coordinates the services concerned.

OIMAP provides experts, a model handover record and logistical support for transport.

Ceremonies and Memory

Each restitution gives rise to a record and, often, an official ceremony. It is also an opportunity to present the history of the property and to raise public awareness of heritage protection.

Associated museums may support the operation with an exhibition or documentation.

Preventing rather than restituting

The best restitution is the one that never has to happen. Registering works, training officials and reporting a theft quickly all reduce the need for recourse.

The agreements therefore include a preventive component, notably the exchange of information on items at risk.
