Define the two numbers clearly
Market value (FMV) is the price a willing buyer and seller would agree on under normal conditions—usually anchored by auction results. Insured value (or replacement value) estimates what it would cost to purchase a comparable item at retail if yours were lost tomorrow. They rarely match because the retail art market includes dealer markups, conservation, and sourcing costs that auctions do not. Treat them as complementary, not competing, metrics.
Why insurers demand replacement value
When a carrier underwrites a scheduled policy, it needs to know how much cash is required to make you whole quickly. That might mean flying a specialist to locate another painting, covering import taxes, and framing the new piece. Those realities push replacement value 20–60% above FMV. During a claim the adjuster will compare your appraisal with current retail offerings, so make sure your report cites galleries or dealer price lists, not just auction comps.
When fair market value rules the conversation
- Estate tax filings and charitable donations must use FMV and reference IRS Form 8283.
- Divorce settlements and equitable distribution typically default to FMV so each party receives an objectively measured amount.
- Selling through auction or private treaty is anchored to FMV because that reflects what buyers are actually paying.
Build a documentation packet that covers both
Request that your appraiser includes two values when appropriate: one for FMV (supported by recent auction comps) and one for replacement (supported by retail quotes). Reference the purpose directly in the report—"Insurance schedule update," "Donation to museum," etc.—so auditors and adjusters understand the intent. Keep PDFs, invoices, and correspondence in a shared drive that your attorney or executor can access if needed.
Keep valuations fresh
| Scenario | Update cadence | Why it matters |
|---|---|---|
| Insurance schedule | Every 2-3 years or after a major market move | Prevents being underinsured when replacement costs spike. |
| Estate & gifting | Before filing tax paperwork | IRS expects current FMV, not a ten-year-old number. |
| Active sellers | Before consigning | Shows whether auction or private sale will net better results. |
