What the Desk does

The Desk receives requests, checks that the documents are admissible, assigns them to accredited experts or the relevant services, and then issues the final document. Each work or transaction receives a unique number, which then serves as a reference in all procedures.

The Desk does not replace the seller or the judicial authority. It attests, verifies and documents; it does not set prices and does not settle disputes, which fall under arbitration.

Who it is for

Individuals register their property and request certificates before a sale or for insurance. Professionals obtain import-export licences and sales approval. Museums and public officials benefit from a reduced scale of 50%.

National authorities may also use it to verify a document presented at customs or during an inspection, through online verification.

Available services

Ten services are offered: registration of a work, certificate of authenticity, certificate of provenance, title of ownership, import-export licence, sales approval, conservation report, digital certification, conformity label, and reporting of theft or loss.

Each has its own timeframe and indicative fee, shown in the table below. Reporting a theft or loss is free and triggers a BIOP alert within twenty-four hours.

A four-step process

Every procedure follows the same pattern: account creation, submission of the request with supporting documents, review by the competent service, and then issuance of the document. At each stage, the applicant receives a message and can check the status of the case.

This common pattern avoids having to learn a new procedure for each service. Documents already submitted remain available in the account and can be reused for a new request.
