When to Update an Artwork Appraisal or Insurance Value

An appraisal does not remain current forever, and an insurance schedule does not update itself when markets, condition, location, or policy terms change. There is no universal interval for every work and purpose. Begin with the requirements of the insurer, tax authority, estate professional, lender, or other intended user.

Record the appraisal’s purpose, value definition, effective date, appraiser, scope, inspection date, assumptions, and intended users. A fair-market-value report prepared for a donation should not automatically be reused as replacement-value support for insurance.

Revisit documentation after a significant new acquisition; a material change in the artist’s market; major exhibition or representation change; damage, conservation, reframing, or altered condition; relocation or loan; policy renewal; inheritance or estate planning; proposed gift, sale, collateral use, or legal proceeding.

Ask how often scheduled values and supporting documents must be refreshed, whether automatic increases apply, and what happens if a work is underinsured or overinsured. Provide updated photographs, location, condition, invoice, and appraisal as requested, and obtain written confirmation of changes.

A single asking price, record auction, social-media event, or unsold listing does not necessarily reset the value of your object. Ask the appraiser which comparable evidence is relevant and whether a desktop update or a full new inspection is appropriate for the intended use.

• Purpose and effective date recorded
• Insurer or intended user’s interval confirmed
• Material market, condition, or use changes logged
• Current object photographs and documents ready
• New assignment commissioned when purpose changes

Review the collection’s value documentation annually as an administrative check, then update individual reports according to policy requirements and meaningful triggers. The goal is fit-for-purpose evidence, not a constantly rising number.
