Is this your first art purchase?
To acquire a work of art safely and with lasting value, it is essential to request a certificate of authenticity and to examine other important documents such as provenance records, sales contracts, and invoices. These documents not only protect the buyer but also guarantee the authenticity and future value of the artwork.
Important Documents for Buying Art
Certificate of Authenticity
- Confirms the originality of the artwork and its attribution to the artist.
- It must include the following information: artist's name, title of the work, date of creation, technique, dimensions, and signature.
- For added security, it may include a serial number or a unique code.
Provenance (Ownership History)
- Documents the previous owners of the artwork.
- It is crucial to ensure that the work is not stolen or forged.
Sales Contract
- Sets out the terms of the transaction: price, reproduction rights, delivery, and any warranties.
- It protects both buyer and seller in case of a dispute.
Invoice or tax receipt
- Ensures the legality of the transaction and serves as proof for insurance or resale purposes.
Additional documents
- Export/import certificates (if applicable).
- Conservation or restoration reports.
- Letters of recommendation from recognized galleries or auction houses.
Risks and precautions
- Forgeries: The art market is vulnerable to copies and falsely attributed works. A certificate of authenticity is the first line of defense against this risk.
- Works of unclear provenance: These may be associated with illegal trade.
- Purchases without a contract: These leave the buyer without legal protection.
Practical steps for document verification
- Request a certificate: Ask the seller for a certificate of authenticity signed by the artist or a recognized institution.
- Check provenance: Inquire about the ownership history and ensure the artwork is not connected to theft or legal disputes.
- Have authenticity verified at galleries or auction houses: Ensure the artwork has been authenticated by recognized institutions that guarantee its authenticity.
- Review the contract: Make sure the sales contract details the price, terms, and usage rights.
- Keep the receipt: Request an official receipt to document the purchase and facilitate insurance or a later resale.
- In summary, while the certificate of authenticity is the most important document, it should be supplemented by proof of provenance, a contract, and an invoice to ensure a secure purchase with long-term value.
