What Is a Probate Valuation in California?
When a California homeowner dies, the probate court needs one official number for the house: its fair market value on the day the owner died. That number — the probate valuation — quietly controls more of the process than most families expect. It goes on the court inventory, it can set the floor for the sale price, and it becomes the tax starting point for whoever inherits the property.
This article explains the valuation in plain English. It is general information, not legal advice, and it does not tell an executor, administrator, or heir what to do in a particular case. Valuation questions belong to the estate's California probate attorney; tax questions belong to a CPA.
What is a probate valuation?
A probate valuation is the official fair market value of a decedent's property as of the date of death. In California, a court-appointed probate referee sets that number — not the executor, the heirs, or the listing agent. The value is recorded on the Inventory and Appraisal (Judicial Council Form DE-160), which the personal representative files with the court.
The phrase sounds like an opinion. It is not. A probate valuation is a legal event: a neutral professional, appointed by the court, states under the court's authority what the property was worth on a specific past date. Families sometimes arrive expecting a conversation about what the house “should” sell for. The referee is answering a different question — what it was worth when the owner died.
Who sets the value of a house in probate?
The probate referee sets it. The court clerk assigns an independent referee from the county's panel once the case opens; the executor cannot choose their own appraiser or assign the value themselves. The referee studies comparable sales and property characteristics, then files the official appraisal with the court on Form DE-161.
This surprises executors who have already paid for a broker's opinion or an independent appraisal. Those documents can be useful for marketing, but the court works from the referee's number. The referee's independence is the point: the value in the court file does not come from anyone with a financial interest in the sale price. For the longer version of the referee's process, see how the California probate referee sets real estate value.
How much does a probate valuation cost?
The referee is paid a statutory commission: one-tenth of one percent (0.1%) of the value of everything appraised, with a $75 floor and a $10,000 cap per estate (California Probate Code §§ 8961, 8963, as in effect January 2026). On a $700,000 house appraised alone, the fee is $700. It is paid from estate funds as an administration expense.
There is no separate invoice to negotiate. The commission is set by statute, so the only variable is the appraised value itself. If the cost side of probate appraisals is on your mind more broadly, the date-of-death appraisal cost breakdown covers what heirs actually pay.
How does the probate valuation affect the sale price?
In a court-confirmation sale — where the executor has limited authority — the property must sell for at least 90% of the referee's appraised value (California Probate Code § 10309, as in effect January 2026). With full authority under the Independent Administration of Estates Act, the executor has more flexibility, but the appraised value still anchors negotiations and the estate's accounting.
The 90% rule is the one that catches families off guard. An offer that looks strong in a normal market can be unworkable in a confirmation sale if it lands below the statutory floor. This is one reason the valuation deserves attention early: the referee's number, set months before the listing, can still be constraining the sale when offers arrive.
Is a probate valuation the same as a listing price?
No. The referee values the property as of the date of death, which may be months before the listing. A broker's comparative market analysis prices the home for today's buyers. Both numbers matter — the referee's for the court record, the agent's for the market — and they often differ. Neither is a prediction of the final sale price.
Think of them as two photographs taken at different times for different audiences. The referee photographs the past for the court. The agent photographs the present for buyers. When the two numbers disagree, that is normal — not a sign that one of them is wrong.
The valuation also sets the tax starting point
The referee's number does not stay in the court file. The date-of-death value becomes the starting point for the property's tax basis — the figure capital-gains math is measured from if an heir later sells the property. That is a tax question, and it belongs to your CPA, not your agent. But it is worth knowing that the valuation has a life beyond the probate case, which is another reason accuracy matters.
What if the family disagrees with the valuation?
Disagreement usually means one of two things: the family believes the referee missed something about the property, or the number creates a practical problem for the sale. Either way, the question belongs to the estate's probate attorney, not the real estate agent. An agent can explain how the number affects marketing and the sale timeline; only the attorney can advise on what can be done about the number itself.
