Why is it necessary to have a RICS probate valuation rather than an estate agent's appraisal?

A RICS probate valuation is necessary where an estate needs a defensible, independent figure for a property at the date of the deceased owner’s death. An estate agent’s appraisal can indicate an asking price or likely sale range, but it is generally prepared for marketing and is not a substitute for a formal valuation when the property forms part of probate, inheritance tax reporting or an estate dispute.

The key distinction is purpose. An estate agent normally assesses what the property might achieve on the open market, often with the intention of securing an instruction to sell it. The assessment may draw on local listings, recent sales and the agent’s experience, but it is not usually a detailed professional valuation report. A RICS probate valuation is prepared for estate administration and records the assumptions, evidence and reasoning behind the figure.

Probate valuations also deal with a specific valuation date. This is usually the date of death, rather than the date on which the executor requests the report or puts the property on the market. A surveyor may therefore need to consider historic comparable sales, changes in local market conditions and the property’s condition at that earlier date. A current estate agent’s opinion may not reliably establish what the property was worth at the relevant point in time.

A formal report is particularly important because the valuation can affect the estate’s inheritance tax position. Executors have a duty to provide accurate information about estate assets. If HMRC questions the figure, a reasoned report from an appropriately qualified surveyor gives the executor evidence showing how the value was reached. An informal appraisal may not contain enough detail to support the figure or answer technical questions about the valuation method.

A RICS valuation can also account for matters that may be overlooked in a sales appraisal, including:

• the property’s condition and any defects that would influence market value;
• the legal title, tenure and restrictions that are relevant to value;
• lease length, service charges or other leasehold considerations;
• planning permissions, lawful use and development potential;
• rights of way, covenants or access issues; and
• any unusual characteristics that make straightforward comparison difficult.

This does not mean that a probate valuation is always a full building survey or a legal investigation. The report will normally state its inspection scope, assumptions and limitations. Executors should provide the surveyor with relevant documents, including title information, leases, planning records and details of known defects, so that the valuation is based on the fullest available evidence.

Independence is another important reason for choosing a RICS valuation. An estate agent’s appraisal may be influenced, consciously or otherwise, by the need to attract a seller or secure a future listing. A probate valuation is intended to provide an impartial professional opinion. That independence is valuable where beneficiaries disagree about the property’s worth, where the executor must justify decisions, or where the valuation may later be reviewed by HMRC or challenged in legal proceedings.

The report can also help with later changes to the estate’s tax position. If the property is sold for materially more or less than the probate figure, the executor may need to consider whether the original valuation remains supportable and whether further tax reporting is required. A properly documented valuation provides a clear starting point for examining that difference, although it does not remove the executor’s responsibility to obtain tax advice where necessary.

An estate agent’s appraisal still has a practical role. It may help an executor understand a possible marketing strategy, choose an asking price or compare likely offers. However, it should be treated as sales guidance rather than evidence prepared for probate. In a straightforward estate with no tax or dispute concerns, an executor may decide that an informal estimate is sufficient for an initial assessment, but that decision should be considered alongside the estate’s reporting obligations and the value of the property.

In practice, the appropriate approach is to appoint a surveyor with relevant valuation experience, explain that the report is for probate, and request that the valuation is stated as at the date of death. The executor should retain the completed report and supporting documents with the estate records. This creates a clearer audit trail than relying solely on an agent’s appraisal and reduces the risk that the property value will later be viewed as unsupported or based on the wrong date.
