Building a solid application

The title application presupposes established provenance and a justified right of ownership. It follows the usual Desk procedure, with one additional step: publication and the 30-day opposition period.

The file rests on three pillars: proof of current ownership, the history of possession, and the absence of any known claim.

The better the provenance is documented, the faster the processing; a certificate of provenance issued by OIMAP is the best basis.

  • Proof of ownership
  • Provenance
  • Absence of claims

Case study: a title for a work acquired at auction

A file in ten days

Situation

A collector acquired a bronze at a public sale four years ago.

Actions
  1. They file the auction record and the invoice.
  2. A certificate of provenance already exists.
  3. Processing is reduced to a BIOP check.
Outcome

The title is published in ten days; it becomes enforceable on day 45.

What if an opposition is filed?

A third party claiming a right over the work has 30 days to file an opposition. The title is then suspended and OIMAP offers mediation between the parties, with the help of an independent mediator.

If mediation fails, the matter may be brought before the Arbitral Tribunal or the competent court. The title becomes final only when the opposition is lifted.
