Report a theft

The detailed procedure for declaring the theft of a work: filing a complaint, BIOP record, documents, alert, follow-up and what to do if the work resurfaces.

In the urgency that follows a theft, three actions count: alert the police, document the work and open the OIMAP report. Each hour that passes reduces the chances of finding the work before it is moved or resold.

Reporting a theft is the most used procedure: more than half the records in the BIOP database come from it. An alert published within twenty-four hours is consulted on average by 1,200 operators within the week.

This page guides you step by step, from complaint to restitution.

Circumstances of the thefts reported.

The first actions

Do not touch the scene, call the police and obtain a report. Look for proof of ownership — invoice, certificate, photographs, correspondence — and for the work's condition. Notify your insurer within the time limits in your contract.

Then open the report on the Desk by choosing "Theft". The form picks up the information from the complaint and asks you to attach the photographs. If the work is registered, the OIMAP number pre-fills some of the fields.

Completing the theft record

The record comprises the identity of the work, distinguishing marks, the date and place of the theft, the circumstances (break-in, pickpocketing), the report number, the reporter's contact details and an indication of the value. The latter is not published, but it helps to assess the seriousness.

The more complete the description, the more useful the alert. Attach photographs from the front, side and in detail, as well as earlier catalogues or exhibitions in which the work was reproduced. A work published in a book is easy to recognise.

Alert, relay and follow-up

After verification, the alert is published in the database and passed to subscribed operators, authorised law enforcement and INTERPOL. The unit follows the matches and tells the reporter of any serious lead, without compromising the investigation.

In the event of a discovery, the unit coordinates with the police of the country concerned the verification, the seizure and, where appropriate, the restitution. It can also put you in touch with a specialised lawyer if the work was acquired by a good-faith third party.

Preventing rather than suffering

A complete photographic inventory cuts the time taken to report by several days. For public and private collections, OIMAP recommends an inventory sheet per work, with photographs from several angles, dimensions and distinguishing marks.

Registering works in the OIMAP Registry gives a unique number and a digital passport that make reporting and recognition easier. It is strongly advised for high-value works.
