A reciprocal commitment

OIMAP approval is issued in five days for €540 excluding taxes. It binds the auction house to specific practices and opens access to the conformity label, to the directory and to an accelerated sale approval procedure.
Approval is open to any auction house duly established in a Member State, whatever its size. It is valid for three years and renewable.
This page details the conditions, the procedure, the obligations and the grounds for withdrawal.

Eligibility conditions
The house must be legally established, hold the authorisations needed for its activity in its State, have professional insurance and employ at least one auctioneer or qualified sales manager. It must not have been convicted of handling stolen goods or fraud in the last five years.
It undertakes to respect the approval charter: provenance checks, consultation of the BIOP, transparency of terms of sale, declaration of results, mediation of disputes.



Obligations during approval
An approved house must consult the BIOP database before each sale, keep provenance documents for ten years, declare each result to the Observatory within thirty days and train its staff. It must also inform OIMAP of any change of management, address or speciality.
An audit is carried out every three years. It covers a sample of lots, files and declarations. Minor breaches lead to recommendations; serious breaches may lead to suspension or withdrawal.
What approval changes for buyers
For the buyer, an approved house guarantees that the lot has undergone a check of origin and of the BIOP database. In case of a problem, they have an identified contact and free mediation.
This protection translates into fewer disputes: the post-sale challenge rate is 0.9% for approved houses, against 3.4% for others.
