Twelve points, three situations

The checklists turn the due diligence method into concrete actions. They exist in three versions — purchase, sale, deposit — and two levels — basic and enhanced — and each fits on one page.
They are used by auction houses, galleries and dealers, and by some museums for their acquisitions. They also serve as a reminder for collectors.
This page presents the twelve checkpoints, their logic and how to use them.

The twelve points
Identity: 1. Verify the identity of the seller and the buyer. 2. Identify the beneficial owner. 3. Check the representative's powers. Provenance: 4. Obtain the ownership history. 5. Examine the provenance documents. 6. Check publications and exhibitions.
Lawfulness: 7. Consult the BIOP database. 8. Check export and import licences. 9. Check national protections (listing, inventory). Payment: 10. Identify the origin of funds. 11. Check consistency with the client's profile. Decision: 12. Record the decision and the justification.



Basic or enhanced
The basic list is enough for routine transactions under €10,000 with no warning sign. It is limited to the twelve points with the usual supporting documents. The enhanced list adds further checks for each point: archives, expert opinion, price justification, interview with the seller.
A transaction can move to the enhanced level along the way if a warning sign appears. The file then keeps the trace of this switch.
User feedback
A survey carried out in 2024 among 410 operators shows that 86% find the checklists "useful or very useful". The most satisfied operators are small galleries, for whom they are a first structuring of compliance.
The main requests for improvement concern integration with existing management tools and translation into more languages. The Secretariat is working on this with the market's software publishers.
