As of June 1, 2017 the Foundation no longer issues certificates of authenticity for paintings.

Since March 1, 2016 the Foundation does not process authenticity requests for works on paper and works on paper mounted on canvas (papier marouflé sur toile). Previously issued certificates remain valid.

The certificate belongs to the work of art and must be passed on to the next owner.

Certificates will not be re-issued by the Foundation in case of loss or changed ownership.
