What we check, and what it means.

A work carries the Rare Form Verified designation only when every applicable check below has been completed.

• ✓ Seller identity verified
  The legal identity of the selling party has been reviewed against government-issued documentation.
• ✓ Ownership documentation reviewed
  Invoices, receipts or transfer records evidencing the seller's title to the work have been supplied and reviewed.
• ✓ Provenance reviewed
  The recorded ownership chain has been examined for internal consistency and against available public records.
• ✓ Condition report completed
  A condition report has been prepared by Rare Form or an approved conservator and is available to the acquiring collector.
• ✓ Authentication documentation reviewed
  Certificates or authentication issued by an estate, foundation or recognised authority have been supplied and reviewed for consistency.

Document review is not authentication. Reviewing certificates, provenance or ownership records establishes that the paperwork supplied is present and internally consistent — it does not itself constitute attribution or independent authentication unless Rare Form expressly states that an independent authority has confirmed the work.

Seller diligence

• Seller verified
  Identity of seller confirmed.
• Ownership documentation reviewed
  Seller-supplied ownership documentation has been reviewed for internal consistency. This is not authentication or attribution.
• Physically inspected
  The work has been physically examined by Rare Form or an approved specialist.
• Authentication documentation reviewed
  Recognized authentication documentation has been reviewed where applicable.

Authentication status

• Not yet authenticated
  No authentication documentation has been supplied to Rare Form for this work. Ownership documentation review is separate from, and does not constitute, authentication.
• Seller documentation provided
  The seller has supplied supporting documentation. Rare Form has not yet independently reviewed it.
• Rare Form documentation reviewed
  Rare Form specialists have reviewed the seller-supplied documentation and confirmed it is internally consistent.
• Third-party authenticated
  An independent authority — estate, foundation, or recognised specialist — has issued authentication documentation.
• Authentication confirmed
  Rare Form has reviewed third-party authentication and independently verified the supporting documents.

Provenance

• Documented
  The ownership chain is substantiated by documents held on file.
• Partially documented
  Part of the ownership chain is documented; gaps are disclosed.
• Seller-reported
  Provenance is as stated by the seller and not yet substantiated.
• Under review
  Provenance is currently being examined by the Rare Form desk.

• Who is selling
  Every work states whether it is offered by Rare Form, a gallery, or a private consignor.
• Payment
  Payment is processed through Stripe and every order is recorded. Condition discrepancies may be raised within five business days of delivery.
• Shipping
  Protected transactions ship with insurance appropriate to declared value and shipment terms, crated and handled by specialist art shippers.
• If something is wrong
  Discrepancies are reviewed by the Rare Form desk with access to documents, messages and shipment records on both sides.

Market context published on a work is drawn from recorded public sale results. Where reliable data does not exist, the metric is omitted rather than estimated. Historical information is context, not a prediction of future value, and nothing on Rare Form constitutes investment advice.
