We take very seriously our commitment to sellers, buyers, and claimants alike to:
Our team is committed to promoting a clear and balanced approach for dealing with provenance issues and ownership claims from the Nazi-era, including taking reasonable and appropriate steps to prevent stolen objects from circulating in the art market and, in particular, aiming to resolve provenance issues before offering objects for sale.
Christie’s handling of Nazi-era art spoliation is inspired by the Washington Conference Principles. Where concerns are identified or claims received for works of art consigned to Christie’s, we are committed to seeking fair and just resolutions. Acting as facilitators for dialogue, our aim is to bring about productive and open discourse and to help claimants and claim recipients to make considered decisions.
We are privileged to work as both part of the art world and as part of the restitution community. We invite you to contact one of our specialists should you have a restitution or provenance query.
