How Fine Art Is Valued: DDR vs FMV

Appraisers are sometimes asked, informally, "what is this work worth?" as though the question had one answer. It does not. Value depends on the purpose the appraisal serves, and two standards recur often enough in estate and tax contexts that they are worth explaining on their own terms: the Date of Death appraisal, commonly abbreviated DDR, and Fair Market Value, or FMV.

A Date of Death appraisal establishes the value of a work as of a specific, fixed date — the date of an owner's death — for purposes of estate tax filing and probate administration. Because the relevant date is fixed by the event itself, a DDR appraisal is necessarily retrospective: it asks what a work would have sold for, between a willing buyer and a willing seller, at that particular moment, using comparable sales and market conditions from around that date rather than current ones. A work appraised years after death for estate purposes still requires research into the market as it stood on the date in question, which is one reason DDR work often takes longer than a straightforward current valuation.

Fair Market Value is a standard rather than a fixed date — it is the definition of value most commonly applied to charitable donations, gift tax filings, and many equitable distribution matters, including divorce settlements. FMV is defined, in the language tax authorities use, as the price at which property would change hands between a willing buyer and a willing seller, neither being under compulsion to buy or sell, and both having reasonable knowledge of the relevant facts. A DDR appraisal is, in effect, an FMV appraisal pegged to a specific historical date; the two concepts share a definition of value and differ chiefly in which date the appraiser is asked to value the work as of.

Both standards are distinct from insurance replacement value, which is generally the highest of the common valuation figures because it reflects the cost of replacing a work at retail — through a gallery or dealer — rather than what the work would realize if sold on the open market. Confusing replacement value with FMV or DDR is a frequent and costly error: a retail replacement figure submitted on a tax filing can be challenged, and an FMV figure used for insurance purposes will typically understate what it would cost to replace a lost or damaged work.

Because these standards produce materially different numbers for the same object, the first and most consequential decision in any appraisal assignment is establishing which standard the intended use actually requires — before research or comparables are assembled, not after. An appraisal prepared to the wrong standard is not simply less useful; it can expose an estate, a donor, or a divorcing party to challenge, penalty, or a valuation that will not withstand scrutiny from the relevant tax authority or court.
