Date-of-Death Appraisal in California Trust Administration

Date-of-Death Appraisal in California Trust Administration

A date-of-death appraisal is a professional valuation that establishes what a trust asset, usually real property, was worth on the exact date the trust’s creator died. It is not the county’s assessed value and it is not what the asset is worth today. It is the single number that stepped-up basis, Prop 19 calculations, and the trustee’s accounting to beneficiaries all get built on top of, and a trustee who sells an asset without one has no defensible way to prove what it was worth when the clock started.

I see this go wrong constantly. A trustee lists the house, sells it eight months later, and only then thinks about what the basis is for tax purposes. By then the appraisal, if anyone bothers to get one, is reconstructing a value from months ago instead of documenting it in real time. That’s backwards, and it’s avoidable.

Why it isn’t optional paperwork

Three separate things ride on this one number, and each has real financial consequences if it’s wrong.

Stepped-up basis under IRC section 1014

When someone dies owning an asset, federal tax law resets that asset’s basis to its fair market value on the date of death. Say your parent bought their Camarillo house in 1988 for $110,000, and it’s worth $850,000 the day they die. Under the stepped-up basis rules, the trust’s basis in that house isn’t $110,000 anymore, it’s $850,000. If the trustee sells it for $860,000 a few months later, the taxable gain is roughly $10,000, not $750,000. That’s the entire point of the rule, and it only works if the $850,000 is a number someone can actually defend. A licensed appraisal is what supports that number if the sale is ever questioned by the IRS or a beneficiary. Without one, a trustee is guessing, and guessing invites scrutiny. For the fuller mechanics of how the step-up works, see our page on stepped-up basis in California trusts. If the house was community property, the step-up can apply to the entire asset rather than just the deceased spouse’s half, which we cover in community property step-up vs. separate property in California.

Proposition 19 property tax calculations

If the property is transferring to a child and the family wants to claim the Prop 19 parent-child exclusion from reassessment, the property’s fair market value at transfer determines whether it falls within the adjusted exclusion cap, currently $1,044,586 (in effect February 2025 through February 2027, and it adjusts every two years), or triggers a partial reassessment on the excess. If the appraised value comes in at $1,200,000 and the parent’s original assessed value plus the cap covers $1,044,586, roughly $155,000 of value gets added to the assessed value going forward, raising the property tax bill. Get the appraisal number wrong, low or high, and the exclusion math is wrong too, which can mean either an inflated tax bill the family didn’t need to pay, or an exclusion claim that gets kicked back by the assessor’s office. See Prop 19 parent-child exclusion explained and Prop 19 and inherited property tax reassessment for how the cap actually works.

The trustee’s accounting to beneficiaries

Under California Probate Code section 16062, a trustee generally owes beneficiaries an accounting that includes the value of trust assets. If a beneficiary later questions how the trust’s property was valued or divided, a defensible, professionally supported appraisal is what protects the trustee. “I asked a real estate agent what she thought it was worth” is not the same thing, and it will not hold up the same way in a dispute.

How to actually get one

For real property, that means hiring a licensed real estate appraiser, not a real estate agent’s comparative market analysis and not the county assessor’s number. A CMA is a sales pitch dressed up as an opinion, useful for pricing a listing, not defensible as a tax or fiduciary document. And the county’s assessed value is frequently far below actual market value in California because Proposition 13 caps how much assessed value can grow each year while a property is owned. A house assessed at $180,000 that’s actually worth $850,000 is not an unusual gap after thirty-plus years of ownership. The appraiser needs to be told the date of death, not the date you’re calling them, because the report has to value the property as of that specific past date, using comparable sales from around that time.

For securities and brokerage accounts, the standard approach uses the average of the high and low trading prices on the date of death. Brokerage firms and financial advisors can typically pull this directly from historical trading data, and it doesn’t require hiring an outside appraiser. Some estates elect an alternate valuation date six months after death instead of the date of death, which can make sense if asset values are dropping and the estate wants a lower basis reported for estate tax purposes. That election is all-or-nothing for the whole estate, though, not asset by asset, and it has its own filing rules, so it’s not something to decide casually.

For business interests, closely held stock, or unusual assets like art, mineral rights, or a working farm, a formal business or specialty valuation may be necessary. That’s a more involved process, sometimes taking months, and it should start early given how long a thorough valuation can genuinely take.

Timing: do this early, not when escrow opens

The most common mistake I see is treating the appraisal as a step that happens right before a sale, instead of something ordered as close to the date of death as practical. Waiting creates two separate problems.

First, property values move. An appraisal ordered a year after death reflects a different market than the one that existed on the actual date of death, and the appraiser then has to reconstruct backward using older comparable sales, which is a less precise and sometimes contentious process, especially if a beneficiary disagrees with the number. Second, other deadlines are running in parallel. The window to claim the Prop 19 parent-child exclusion runs from the date of the transfer, and the appraisal often needs to be in hand before that filing makes sense. Waiting on the appraisal can mean scrambling on the Prop 19 filing too. We cover that filing process in how to file for the Prop 19 parent-child exclusion.

What happens once the appraisal is in hand

With a documented fair market value, the trustee can move forward on everything that was waiting on it: calculating basis for a future sale, filing any applicable Prop 19 claim, and preparing the accounting that supports final distribution to beneficiaries. If the trust holds capital-gain property that later sells for more than the stepped-up basis, that gain gets handled under the rules we walk through in capital gains on inherited property in California. And because the appraisal often surfaces the community-versus-separate property question for a married decedent’s estate, it’s worth reading alongside our page on community property vs. separate property in trust administration.

The honest caveat

An appraisal is a snapshot, not a guarantee. Two competent appraisers can land on numbers that differ by five or ten percent for the same property on the same date, especially in a market with few recent comparable sales. It won’t settle a genuine family dispute about whether the house is “worth more than that,” and it doesn’t protect a trustee who ignores the appraised value and sells for something obviously lower to move things along faster. What it does is give you a defensible, professionally supported starting point, which is worth a great deal more than a guess, but it isn’t a substitute for good judgment on everything that comes after.

Talk to a real California estate attorney

If you’re serving as trustee and haven’t ordered a date-of-death appraisal yet, don’t wait until a sale is imminent. I’ll look at what the trust holds, tell you what needs to be valued and by whom, and make sure the number you get is one that will actually hold up later.

Frequently asked questions

What is a date-of-death appraisal?

It’s a professional valuation, prepared by a licensed appraiser, establishing what an asset was worth on the exact date the trust’s creator died. It’s not the county’s assessed value and not today’s market value. It’s the number that supports stepped-up basis, Prop 19 calculations, and the trustee’s accounting to beneficiaries.

Why can’t a trustee just use the county’s assessed value?

Proposition 13 caps how much a property’s assessed value can grow each year while it’s owned, so by the time of death the assessed value is often far below actual market value. Using it instead of a real appraisal understates basis, which can turn a modest capital gain into a large, unnecessary tax bill on a later sale.

How soon after death should a trustee order the appraisal?

As soon as practical, not right before a sale. Values move over time, and other deadlines run in parallel, including the one-year window to file for the Prop 19 parent-child exclusion. Ordering the appraisal early keeps every later calculation clean and keeps the file defensible if anyone questions it.

How are securities and brokerage accounts valued as of the date of death?

The standard method uses the average of the high and low trading prices on the date of death, which a brokerage or financial advisor can pull from historical data. Some estates elect an alternate valuation date six months after death instead, but that election applies to the whole estate, not asset by asset, and has its own rules.

What happens if a trustee sells property without ever getting a date-of-death appraisal?

The trustee has no defensible number to support the basis used on the capital gains calculation, and no documented value to show beneficiaries in the accounting. If the IRS or a beneficiary later questions the numbers, the trustee is reconstructing value after the fact, which is harder, less reliable, and can expose the trustee to a fiduciary duty claim.
