Provenance, certificates and condition reports, the papers that matter
Behind every artwork that changes hands sits a paper trail. What provenance proves, what certificates and condition reports can and cannot tell you, and how to keep your own file.
Behind every artwork that changes hands sits a small archive: invoices, letters, labels on the back of a frame, a mention in an exhibition catalogue. Collectors call it the paper trail. It can confirm who made a work, show that the seller has the right to sell it and reveal whether its past includes theft or persecution. Knowing which papers matter, and what each can and cannot prove, is one of the quiet skills of collecting.
What provenance is and why it matters
is the history of an artwork’s ownership, ideally from the artist’s studio to the present day. A strong provenance names previous owners, dates and places, and is backed by documents: sales records, exhibition catalogues, gallery stock books, letters and old photographs.
It matters for three reasons. It supports authenticity, because a continuous history makes it harder to slip a forgery into the record. It supports legal title, because a work that was once stolen can remain subject to claims from its rightful owner even after several sales, although the rules differ from country to country. And it matters ethically, because some histories hide wrongs that have not been put right.
The best known example is art taken from Jewish owners and others persecuted under the Nazi regime between 1933 and 1945. In 1998, 44 governments endorsed the Washington Conference Principles on Nazi-Confiscated Art, a set of non-binding principles that encourage provenance research, the publication of looted works and fair solutions with former owners or their heirs. , the return of such works, continues today. A gap in the provenance during those years is a reason to ask more questions, not necessarily a sign of wrongdoing.
Catalogues raisonnés and certificates of authenticity
A , French for “reasoned catalogue”, is a scholarly listing of an artist’s known works, or of a defined part of them such as the prints. Entries usually give title, date, medium, dimensions, provenance and exhibition history. Inclusion is itself a judgement about authorship, which is why some artists have more than one catalogue and why scholars sometimes disagree.
A is a document stating that a work is by a particular artist. It is only as reliable as the person or body that issued it. A certificate signed by a living artist or issued by their long-standing gallery carries weight; one from an unknown source adds little. For artists who have died, estates, foundations or committees sometimes give opinions, but not always: the Andy Warhol Foundation, for example, dissolved its authentication board in 2012. Certificates can also be forged, so they should agree with the rest of the paper trail.
Condition reports and what they describe
A is a written description of the physical state of a work at a given moment. Auction houses usually provide them on request, and conservators write more detailed ones. A good report describes the support, such as canvas, panel or paper, and the surface, then notes damage and past treatment.
- Craquelure, the network of fine cracks in old paint or varnish, and whether any paint is lifting.
- Losses and retouching, areas where paint is missing or has been filled and repainted by a restorer.
- Ultraviolet examination, which can reveal later retouching that is hard to see in normal light.
- Paper problems such as foxing (small brown spots), fading, tears, stains and old tape.
- Frame and back, including labels, stamps and inscriptions, which can also be evidence of provenance.
A condition report is an opinion, not a guarantee. Read it before you buy, compare it with what you see, and ask for clearer photographs of anything that worries you.
Invoices, export papers and stolen art databases
An invoice is the most basic proof of purchase and should describe the work fully: artist, title, date, medium, dimensions, edition details and price. Some works also need export documents. In the European Union and many other countries, cultural goods above certain age and value thresholds need a licence to leave, and the rules vary by category and country. If a work has crossed borders, its export papers belong in the file.
Before a work with any history of resale changes hands, buyers, sellers and auction houses often check it against databases of stolen and looted art. A clean result is useful, but it only covers what has been reported.
Keeping your own documentation file
Every collection, however small, deserves a file. It helps with insurance, with any future sale or gift, and with the simple pleasure of knowing what you own.
- Photograph each work front and back, including labels, signatures and any damage, in good even light.
- Scan or file the invoice, certificate, condition report and any correspondence with the seller or artist.
- Note framing details, conservation treatments and the dates of any loans or exhibitions.
- Record where each work hangs or is stored, and update the file whenever anything changes.
- Keep a digital copy in a second place, so a fire or flood cannot take the records with the art.
A gap in the provenance is a reason to ask more questions, not necessarily a sign of wrongdoing.
One last point: arisano gives no legal, tax or financial advice. Questions of title, restitution claims or export licences are matters for a specialist lawyer, and clear written agreements are always worth the effort.

Readers ask
Does a certificate of authenticity prove a work is genuine?
Not on its own. A certificate is only as reliable as the person or body that issued it, and certificates can be forged. It carries most weight when it comes from the artist, their long-standing gallery or a recognised authority, and when it agrees with the rest of the paper trail: invoices, exhibition records and, where one exists, the catalogue raisonné.
What should I do if a work has gaps in its provenance?
Ask the seller what is known and why the gap exists, since many works have incomplete histories for innocent reasons. Gaps between 1933 and 1945, or antiquities with no documented past, deserve particular care. Check the relevant databases and, for valuable works, consider professional provenance research and advice from a specialist lawyer before you buy.
How long should I keep the papers for an artwork?
For as long as you own the work, and then pass them on with it. The documents are part of the work’s history and will matter to the next owner, an insurer or a museum. Keep the originals somewhere safe and dry, and store a digital copy in a second place.
