A probate valuation is a formal, professional assessment of the assets within a deceased person’s estate, carried out to establish their open market value as at the date of death. Solicitors need one because HMRC requires accurate, independently verified asset values before Inheritance Tax can be calculated and a Grant of Probate issued. The sections below address the specific questions solicitors most commonly raise when instructing a probate valuer.
What does a probate valuation actually cover?
A probate valuation covers every category of asset forming part of a deceased person’s estate that carries a monetary value at the date of death. This includes residential and commercial property, household contents, personal possessions, vehicles, jewellery, art, antiques, and collectables. The valuation establishes the open market value of each asset, which HMRC uses as the basis for Inheritance Tax calculations.
In practice, a thorough estate valuation probate service divides into two primary components. The first is a property valuation, which assesses the open market value of any real estate in the estate. The second is a contents valuation, which covers all tangible personal property found within the deceased’s home or homes.
Beyond the headline figures, a complete probate valuation report should also address bequests and specific gifts named in the will, document items of particular significance, and provide supporting evidence for each valuation figure. This level of detail is not optional: it is what distinguishes a report that HMRC will accept without question from one that invites challenge.
Why must probate valuations be carried out by a RICS-accredited valuer?
Probate valuations must be carried out by a RICS-accredited valuer because HMRC requires that estate assets are valued at open market value, and only an independent, professionally qualified valuer can produce a report that meets that standard reliably. As HMRC increasingly scrutinises probate submissions not prepared by a recognised professional, instructing a RICS-registered valuer has become essential practice for solicitors who wish to avoid delays, disputes, or formal investigations.
An RICS Red Book Property Valuation is prepared in strict accordance with the RICS Valuation Global Standards, which mandate independence, objectivity, and transparency. These standards exist precisely to give HMRC, executors, beneficiaries, and the courts confidence that the figures presented reflect genuine market value rather than an interested party’s estimate.
Estate agent valuations, by contrast, are informal marketing tools. They are influenced by the agent’s commercial interest in securing a sale instruction and carry no professional indemnity protection in the valuation context. HMRC does not treat them as equivalent to a RICS-compliant report, and solicitors who rely on them risk submitting an Inheritance Tax account that cannot withstand scrutiny.
For contents, the position is the same. Valuations of art, antiques, jewellery, and household effects must be carried out by a registered and accredited valuer with specialist expertise in those categories. Without that professional standing, a contents valuation has no evidential weight with HMRC.
How does a probate valuation affect inheritance tax calculations?
A probate valuation directly determines the taxable value of an estate. HMRC calculates Inheritance Tax on the total open market value of all assets as at the date of death, less any allowable deductions and available reliefs. If the valuation figures submitted are inaccurate, the Inheritance Tax liability will be wrong, which can result in underpayment, overpayment, or a formal HMRC enquiry.
The legal framework governing this is Section 160 of the Inheritance Tax Act 1984, which defines open market value as the price the asset might reasonably be expected to fetch if sold on the open market at the relevant date. Every figure in a compliant probate valuation report must be defensible against that statutory definition.
The practical consequence for solicitors is significant. An Inheritance Tax account submitted with professionally prepared, RICS-compliant valuations is far less likely to attract an HMRC enquiry than one based on informal or undocumented estimates. Accurate valuations also protect beneficiaries from overpaying tax and protect the executor from personal liability if the figures are later challenged.
What happens if a probate valuation is queried by HMRC?
If HMRC queries a probate valuation, it will open a formal enquiry into the Inheritance Tax account and may instruct its own District Valuer to assess the property or assets independently. This process can delay the administration of the estate significantly, create additional costs, and in some cases result in a revised tax liability with interest and penalties applied to any underpayment.
HMRC queries most commonly arise when valuations lack supporting evidence, appear inconsistent with comparable market data, or have been prepared without professional accreditation. A report produced by a RICS-registered valuer, fully compliant with Section 160 of the Inheritance Tax Act 1984, provides a robust evidential basis that makes a successful challenge rare.
Where a query does arise despite a professionally prepared report, the valuer’s documentation, methodology, and professional standing give the solicitor and executor a credible position from which to respond. This is one of the most practical reasons why solicitors consistently insist on RICS-accredited probate valuation reports rather than accepting informal alternatives.
When should solicitors instruct a probate valuer?
Solicitors should instruct a probate valuer as early as possible in the estate administration process, ideally before the Inheritance Tax account is drafted. Valuations are required to complete the IHT400 or IHT205 forms submitted to HMRC, and the accuracy of those forms depends entirely on having reliable, professionally prepared figures in place before submission.
Early instruction also allows sufficient time for a thorough assessment, particularly in estates involving property, large quantities of contents, or specialist items such as fine art or antiques. Rushing a valuation increases the risk of figures that are insufficiently evidenced or that fail to capture the full scope of the estate.
In time-sensitive cases, a written probate valuation report can be produced within 24 hours where required, but as a matter of best practice, building valuation into the estate administration timeline from the outset avoids unnecessary pressure and reduces the risk of errors that could complicate the Grant of Probate application.
What should solicitors look for in a probate valuation partner?
Solicitors should look for a probate valuation partner who is RICS-accredited, carries full professional indemnity insurance, demonstrates a consistent record of HMRC-accepted reports, and can handle the full scope of an estate’s assets under one instruction. The ability to value both property and contents, including specialist categories such as art, antiques, and jewellery, removes the administrative burden of coordinating multiple third-party providers.
Practical reliability matters as much as technical competence. Solicitors need a partner who delivers reports within agreed timeframes, communicates clearly at every stage, and understands the legal and procedural framework within which estate administration operates. A firm with established relationships across the legal sector and experience supporting a wide range of law firms will understand the standards solicitors require without needing detailed briefing on each instruction.
Additional capabilities are worth considering too. A partner who can also manage probate house clearance, property sales, document retrieval, and vehicle disposal provides genuine end-to-end support that simplifies the entire administration process for the solicitor and their client.
