The process of establishing provenance documentation for your works of art is critical. Nicholson Advisory advocates the highest standards in provenance research, as any potential sales of your property through reputable auction houses or dealers can be difficult without accurate and verifiable records. An unimpeachable provenance can affect the value of a work enormously, and a work without provenance will not realize its full potential at auction.

Enlisting a far-reaching network of colleagues in Europe and in Russia, we examine catalogues raisonnés, auction records, exhibition catalogues, artist correspondence and family history to provide the most thorough review possible. We have exceptional access to databases, archives, and libraries throughout the United States, the United Kingdom, Europe, and Russia.
