Start with the most objective lead available. A catalogue reference can begin from $4.99, while full authentication remains a human expert service.
Expert authentication workflow
Built for collectors, heirs, galleries and market professionals who need a serious answer.
ConfirmArt documents each case through images, support, technique, signature, inscriptions, provenance material and comparative references. The goal is not a quick opinion, but a clear expert file that a client can keep, share and verify.
Every public page keeps the same conversion path: open a private authentication case, add images when available, and continue the review through the client workflow.
Document the object
Front, reverse, signature, labels, frame, support and provenance are organized.
Review the evidence
The work is assessed through visual, technical, historical and comparative criteria.

FAQ
Common questions before opening a case
Is the verdict made by AI?
No. ConfirmArt authentication is human-led. AI may support bounded research tasks such as image search, market data, document tracking or charting, but it does not decide attribution.
What should I send first?
An email is enough to open a case. The most useful images are the full front, reverse, signature, labels, inscriptions, frame, support and any damage or restoration details.
What is included in valuation?
Valuation is built from documented market research, comparable works, condition, scale, medium, attribution strength and the practical context in which the artwork may be offered.
Will my private report be public?
No. Public pages show selected real-case samples and rendered report images. Private client reports, emails, source documents and identities remain controlled by the client.

Request Authentication Service
Only your email and service selection are needed to submit the request. Optional images, dimensions and notes can be added now or later.
Payment is requested only for the Authentication report. Catalogue search, advisory, restoration and local inspection requests are reviewed first so the scope can be confirmed.
Authentication is a human expert review. ConfirmArt may use AI for bounded research support such as database, image, book or provenance searches, but not as a classifier verdict.
