What Is a Probate Valuation? A Complete Guide for Executors

A probate valuation establishes an asset's Open Market Value at the date of death. The personal representative needs reasonable values for the estate administration and, where applicable, the Inheritance Tax account. Some figures can be supported by ordinary records or reasonable estimates; valuable, unusual or difficult-to-value assets may justify a professional report.

The purpose is straightforward: HMRC needs to know what the deceased's assets were worth in order to calculate any Inheritance Tax that is due. For property, personal possessions, investments, and other assets, the executor must provide values that reflect what each asset would realistically fetch if sold on the open market on the date the person died — not what the family thinks it is worth, not what was paid for it, and not what it might sell for in ideal circumstances.

Probate valuations cover all types of assets within the estate. The most commonly valued items include residential property, jewellery, watches, art and paintings, antiques, classic cars, gold and precious metals, and valuable collections. Each category requires specialist knowledge, and different professional qualifications apply to different asset types.

Probate value means the Open Market Value of an asset at the date of death — the price it would realistically fetch if sold on the open market between a willing buyer and a willing seller, both with reasonable knowledge of the relevant facts. It is sometimes called the date-of-death value or the estate value.

The term is used in two slightly different ways, which is a common source of confusion. Applied to a single asset, the probate value is that item's Open Market Value on the day the person died. Applied to the estate as a whole, the probate value is the total of all those figures — property, money, investments and personal possessions — with debts and liabilities deducted to give the net figure.

What probate value is not: it is not the insurance replacement value, which is usually higher because it reflects retail prices. It is not the price originally paid, which may bear no relation to current worth. And it is not what the family believes an item to be worth. Only the open-market figure at the date of death is relevant to the estate return.

Every estate that requires a Grant of Probate (or Confirmation in Scotland) must include accurate values for all the deceased's assets. However, the level of professional input required depends on the nature and value of the assets:

HMRC does not set a universal £1,500 threshold requiring every personal chattel above it to be professionally valued. Its guidance says you can obtain a professional valuation for anything worth over £1,500 and should consider specialist help where an asset may be valuable or is difficult to estimate. Form IHT407 separately requires each jewellery item worth £1,500 or more to be listed and asks for a professional valuation to be attached if one was obtained.

For property, there is no equivalent £1,500 rule. The HMRC Valuation Office Agency can review property values declared on Inheritance Tax returns. A RICS-qualified surveyor's report can provide independent methodology and comparable evidence, but the VOA can still propose a different value.

The probate application still needs reasonable gross and net estate figures where no Inheritance Tax is due. The level of professional input can be proportionate to the assets and the applicable reporting route.

Executors are often handed figures that look authoritative but were prepared on an entirely different basis. The table below shows which ones can be used for the estate return and which cannot:

The following categories commonly benefit from professional probate valuation when the asset is valuable, unusual or difficult to estimate. HMRC does not prescribe one qualification for every category, so check relevant expertise, methodology and supporting evidence.

While the specific process varies by asset type, probate valuations generally follow a consistent pattern. Understanding this process helps executors plan their time and set expectations.

The first step is identifying which assets require valuation and engaging appropriate professionals. For estates with multiple asset types — jewellery, paintings, and a property, for example — different specialists may be needed. Some valuers cover multiple categories, particularly for home visits where jewellery, art, antiques, and other chattels can be assessed in a single appointment.

The valuer then inspects each asset in person or, where appropriate and with any limitations explained, from detailed photographs and records. During an inspection, the valuer examines, measures, photographs and documents the asset, noting condition, distinguishing features, hallmarks, signatures and other factors affecting value.

Research into comparable sales is the next critical step. The valuer investigates recent auction results, dealer transactions, and market data to establish what similar items have actually sold for. This evidence-based approach produces a defensible figure rather than an opinion.

Finally, the valuer produces a report detailing each asset, the evidence considered and the assessed Open Market Value at the date of death. The figures feed into the applicable probate and Inheritance Tax reporting route; retain the report and attach it where the relevant form asks for it.

There is no standard fee. Providers may quote by item, by hour, by visit or as a fixed price for a defined collection, so ask for a written scope before instruction.

One point is worth stating plainly: properly incurred valuation fees can ordinarily be paid from estate funds as an administration cost, but they cannot be deducted from the estate value when calculating Inheritance Tax. HMRC's IHT400 notes specifically exclude valuation fees incurred in dealing with the estate.

Inaccurate probate valuations create risks for executors in both directions.

If HMRC concludes that an asset was materially undervalued, additional tax and interest may become due. Whether a penalty applies depends on the conduct and circumstances, including whether reasonable care was taken; a mistaken estimate does not automatically attract the maximum penalty.

Overvaluing assets can cause the estate to report or pay more tax than necessary. Correction and relief routes depend on the asset and circumstances, so it is better to use the correct valuation basis and evidence from the outset.

Personal representatives remain responsible for the estate return and should avoid distributing an estate before liabilities are resolved. A professional report can help demonstrate reasonable care, but it does not automatically transfer tax liability to the valuer or guarantee a successful insurance claim.

HMRC does not maintain an approved list or mandate one credential. When professional help is appropriate, choose a valuer whose expertise matches the asset and check the following:

Relevant qualifications and professional membership can support credibility, but HMRC can review any valuation. The report's methodology, market evidence and explanation of assumptions matter as much as the initials after the valuer's name.
