Can a RICS Valuation for Probate be challenged or disputed?

A RICS Valuation for Probate can be disputed, but a disagreement does not automatically invalidate the report. The person challenging it normally needs to show that the valuation is materially unreliable, based on an incorrect interpretation of the property or market, or inconsistent with the valuation standards and instructions that applied at the date of death.

The first issue is identifying who is entitled to raise the dispute and what decision they are challenging. An executor or administrator may question a valuation used in the estate accounts or inheritance tax reporting. A beneficiary may raise concerns with the personal representatives if the figure affects the distribution of the estate. HM Revenue & Customs may also examine the declared value where it is relevant to inheritance tax, and may seek further information or an independent assessment. The Probate Registry is concerned primarily with the grant process; it is not generally the body that determines whether an open-market property valuation is correct.

A challenge is more persuasive when it identifies a specific, material issue rather than simply asserting that the property was worth more or less. Examples can include:

• the report valuing the wrong legal interest, such as an occupied property when the relevant interest was vacant possession;
• an incorrect understanding of ownership, lease length, rights of way, restrictive covenants or other title matters;
• failure to account for planning permissions, enforcement notices, development potential or known restrictions;
• an inaccurate description of the accommodation, condition, access, boundaries, outbuildings or land;
• an assumption that repairs, clearance or remedial work had already been completed when they had not;
• an error in the valuation date or in the interpretation of market conditions at that date; or
• a report that does not clearly explain the method, assumptions and evidence used to reach its conclusion.

The valuation date is particularly important in probate work. The relevant question is usually what the property would have been worth at the required date, rather than what it is worth when the report is commissioned or when it is eventually sold. A later sale price can be relevant evidence, but it is not automatically conclusive because the market, condition, marketing strategy, buyer demand and transaction terms may have changed. The surveyor should explain how any later transaction has been adjusted when considering the historic value.

There is also a distinction between a valuation dispute and a complaint about professional service. A valuation dispute concerns the figure or reasoning. A service complaint may concern missed instructions, delays in obtaining relevant information, inadequate inspection or a failure to explain limitations. These matters can overlap, but they should be set out separately so that the surveyor can respond to each issue clearly.

The usual practical sequence is to read the engagement terms and report carefully, list each disputed point, and ask the original surveyor for a written clarification. Check whether the surveyor was instructed to value the freehold, leasehold or another interest, whether the inspection was restricted, and whether the report was prepared for inheritance tax, estate administration or another purpose. A report may be unsuitable for a particular use even where the underlying inspection was competently carried out.

If the explanation does not resolve the concern, an independent RICS-registered valuer with relevant probate experience may be asked for an opinion. The second valuer should receive the original report, the instruction, title information, plans, photographs and any other material that was available at the relevant date. Full disclosure matters: commissioning an opinion based only on selected information can make the conclusion less reliable and may create further disagreement.

Where the matter is being considered by HMRC, the estate should respond within the applicable correspondence or enquiry process and retain a clear audit trail. The personal representatives should not replace a reported figure informally without recording why the change was made and which professional evidence supports it. If HMRC and the estate cannot agree, specialist tax or legal advice may be appropriate because the available review, amendment and appeal routes depend on the nature and stage of the tax matter.

Beneficiaries should normally direct concerns to the executors or administrators rather than instructing a competing valuation independently without consultation. The personal representatives are responsible for administering the estate, and an independently commissioned report may not be accepted as the estate’s adopted valuation unless its purpose and limitations are understood. Where several beneficiaries are involved, agreeing the instruction and sharing the relevant information can reduce conflicting opinions.

A corrected or replacement report should state what has changed, why the change is justified and whether the revised figure applies to the original valuation date. Minor typographical errors may require only an amended report. A substantial change in the valuation may require revised estate accounts and, where relevant, corrected tax reporting. The effect on inheritance tax, capital gains tax and the eventual distribution of the estate should be considered separately, as a change in probate value can have different consequences at different stages.

Keep the original report, instruction letter, title documents, plans, photographs, correspondence, inspection notes where available and all versions of any revised valuation. If the dispute develops into a professional negligence claim, the court will examine the scope of the instruction, the standard expected of the valuer, the information reasonably available at the time and whether the alleged error caused a financial loss. Legal advice should be obtained before making allegations of negligence or starting proceedings, particularly because time limits and procedural requirements can apply.

In practice, the strongest challenge is precise, evidence-led and focused on issues that could have changed the figure materially. A difference of opinion about market judgement is not necessarily evidence of professional error, whereas a demonstrable mistake about the property, the legal interest, the valuation date or a significant assumption may justify a formal review.
