To value a deceased person’s estate for probate, you must identify and calculate the open market value of all assets owned by the deceased at the date of death. This includes property, savings, investments, vehicles, and household contents. The resulting figure determines whether Inheritance Tax is owed and forms the basis of the estate’s submission to HMRC.
The process must be carried out accurately and in compliance with Section 160 of the Inheritance Tax Act 1984, which defines the standard of valuation HMRC expects. Errors or undervaluations can result in delays, HMRC challenges, or financial penalties. The sections below address the most common questions executors and families face when working through this process.
Who is responsible for valuing a deceased person’s estate?
The legal responsibility for valuing a deceased person’s estate rests with the executor named in the will, or the administrator appointed by the court if no will exists. The executor must compile an accurate account of all assets and liabilities at the date of death and submit this to HMRC as part of the probate process.
While executors carry the legal duty, they are not expected to carry out the valuations themselves. In practice, professional valuers are instructed to assess property and household contents, and financial institutions provide written confirmation of account balances and investment values. The executor’s role is to gather this information, ensure it is accurate, and submit it correctly. Given that HMRC can investigate undervaluations and impose penalties, most executors choose to work with accredited professionals rather than rely on informal estimates.
What assets need to be included in a probate estate valuation?
A probate estate valuation must include the total value of everything the deceased owned at the date of death, minus any outstanding liabilities. This covers all asset classes, regardless of perceived value, and must reflect open market value at that specific date.
Assets that must be included are:
- Residential and commercial property, including any share of jointly owned property
- Savings accounts, current accounts, and cash holdings
- Stocks, shares, and investment portfolios
- Pension funds (depending on the type of pension and its terms)
- Life insurance policies not held in trust
- Vehicles, including cars, motorcycles, and boats
- Household contents, furniture, jewellery, art, antiques, and collectibles
- Business interests and intellectual property
- Money owed to the deceased
Liabilities such as outstanding mortgages, loans, credit card debts, and utility bills are deducted from the gross estate to arrive at the net estate value. This net figure is what HMRC uses to calculate any Inheritance Tax liability.
How is the value of property calculated for probate?
For probate purposes, property is valued at its open market value on the date of death. This is defined as the price the property would reasonably achieve if sold on the open market at that date, between a willing buyer and a willing seller, with neither under any compulsion to transact.
A probate property valuation must be carried out by a qualified RICS-accredited valuer and produced in accordance with the RICS Red Book, the internationally recognised standard for property valuation. An estate agent’s informal estimate is not sufficient for HMRC purposes. The valuation report must be formal, written, and defensible if questioned.
Factors that influence the probate property valuation include the condition of the property at the date of death, local comparable sales, any tenancy agreements in place, and whether the property is being sold with vacant possession. Where a property was jointly owned, only the deceased’s share is included in the estate, though the method of ownership affects how that share is calculated.
How are household contents and personal possessions valued for probate?
Household contents and personal possessions must be valued at the price they would fetch if sold on the open market at the date of death. This applies to all chattels, including furniture, clothing, jewellery, artwork, antiques, collectibles, and everyday household items, regardless of whether they appear to have significant monetary value.
HMRC requires that even modest estates include a proper contents valuation. A common mistake is to assume that ordinary household contents have negligible value and can be estimated informally. HMRC can and does challenge such approaches, particularly where items of higher value may have been overlooked. A professionally produced probate contents valuation, carried out by a Registered and Accredited Valuer, provides a documented, HMRC-compliant record that protects the executor from later dispute.
For estates containing art, antiques, jewellery, or specialist collections, specialist knowledge is essential. Values in these categories can vary considerably based on provenance, condition, and current market demand, and a generalist estimate is unlikely to withstand scrutiny.
What is the inheritance tax threshold and how does the estate valuation affect it?
In 2026, the standard Inheritance Tax threshold, known as the nil-rate band, is £325,000. Estates valued below this figure are generally not subject to Inheritance Tax. The standard rate of Inheritance Tax on the value above this threshold is 40%, though a reduced rate of 36% applies where at least 10% of the net estate is left to charity.
An additional allowance, the residence nil-rate band, applies where a main residence is passed to direct descendants. This currently stands at £175,000 per individual, meaning a qualifying estate can benefit from a combined threshold of up to £500,000. Married couples and civil partners can transfer any unused threshold to the surviving partner, potentially doubling the allowance to £1 million.
The estate valuation directly determines whether any Inheritance Tax is owed and how much. An inaccurate valuation, whether too high or too low, creates risk. An overvaluation results in unnecessary tax being paid. An undervaluation can trigger an HMRC investigation, penalties, and interest on unpaid tax. Precision matters, which is why the standard of valuation required by Section 160 of the Inheritance Tax Act 1984 is so important.
When should you instruct a professional probate valuation company?
A professional probate valuation company should be instructed as early as possible after the death, ideally before the grant of probate is applied for. The estate valuation is a prerequisite for the probate application itself, and delays in obtaining accurate valuations can hold up the entire administration process.
Instructing a professional at the outset is particularly important where the estate includes property, high-value contents, art, antiques, or any assets that require specialist knowledge to value accurately. It is also advisable where the estate is likely to exceed the Inheritance Tax threshold, where HMRC scrutiny is more probable. Even for modest estates, a professionally produced valuation provides legal protection for the executor and removes any ambiguity from the process.
Executors who attempt to value an estate without professional assistance risk producing a report that HMRC will not accept, which can result in significant delays and additional cost. A qualified, RICS-accredited valuer will produce a report that meets the precise standard required, submitted in a format ready for HMRC review.
