Why Accurate Probate Valuations Matter

When a person dies, their estate must be valued accurately for two critical purposes: to apply for a Grant of Probate (or Letters of Administration), which is the legal authority to deal with the deceased's estate; and to calculate whether inheritance tax (IHT) is owed to HMRC. Under-valuing an estate — whether intentionally or through ignorance — can result in HMRC penalties of up to 100% of unpaid IHT, plus interest on the underpaid amount. HMRC has 20 years to open an investigation into IHT fraud and 4 years for non-fraudulent errors.

All assets must be valued at the date of death value — not the value at the time of the probate application (which may be months later). This date of death valuation can be challenging for fluctuating assets like shares or property in a rising or falling market. The valuation basis is the "open market value" — the price the asset could reasonably be expected to fetch if sold on the open market at the date of death.

Assets Requiring Professional Valuation

Residential and commercial property must be valued by an estate agent or RICS-chartered surveyor at the date of death. Two or three estate agent valuations are typically obtained; the figure used for IHT purposes should be the value at which the property would reasonably sell, not a high estimate. HMRC's Shares and Assets Valuation team (SAV) regularly cross-checks property values against actual sale prices — if a property is later sold for significantly more than the probate value, HMRC may challenge the original valuation.

Listed shares and unit trusts use a specific formula: the lower of (a) the price at one-quarter up from the lower quoted price, or (b) the average of the two prices quoted in the exchange's official closing prices on the date of death. For shares not quoted on a recognised exchange, or shares in private companies, a specialist valuations expert is required. Private company share valuations involve complex analysis of the company's accounts, assets, earnings, and comparable transactions — HMRC's SAV will scrutinise these closely.

Jewellery, antiques, fine art, and collectibles need specialist valuation if their combined value could exceed £1,500. Leading auction houses such as Bonhams, Christie's, or Sotheby's provide probate valuations. For everyday household contents below this threshold, a reasonable "second-hand value" estimate is acceptable. Business and agricultural property also need specialist valuation, particularly where Business Property Relief (BPR) or Agricultural Property Relief (APR) may apply — these reliefs can reduce the taxable value by 50% or 100%.

Calculating the Net Estate

The gross estate value is the total of all assets owned by the deceased at the date of death, including their share of jointly owned assets. From this, you deduct allowable liabilities: mortgages and secured loans, credit card debts, utility bills, council tax arrears, income tax or NIC owed for the period to death, and reasonable funeral expenses. The resulting figure is the net estate value for IHT purposes.

Some assets do not form part of the estate for IHT purposes: assets held in trust (including pension funds — though this may change under proposed 2027 reforms); assets passing by survivorship to a joint tenant; death-in-service benefits from employment; life insurance written in trust for beneficiaries; and foreign assets that are not the deceased's legal or beneficial property. Understanding what is "in" and "out" of the estate is crucial for accurate IHT planning.

The Nil-Rate Band and Residence Nil-Rate Band

Every person in the UK has an IHT nil-rate band of £325,000 — no IHT is charged on the first £325,000 of their estate. This band has been frozen since 2009 and is currently frozen until April 2030 under the current government's plans. As UK property and asset values have risen significantly since 2009, more estates are now subject to IHT than ever before — an estimated 6–7% of deaths now result in an IHT liability, up from around 3% a decade ago.

The Residence Nil-Rate Band (RNRB) provides an additional £175,000 allowance where the deceased owned a residential property that forms part of their estate and is left to direct descendants — broadly, children, grandchildren, stepchildren, adopted and fostered children, and their spouses/civil partners. The RNRB tapers away at £2 for every £1 of estate over £2,000,000, disappearing entirely at estates over £2,175,000 with the full RNRB. Both bands can be transferred to a surviving spouse or civil partner, potentially doubling the available allowances.

Executor vs Administrator — Who Deals with the Estate

If the deceased left a valid will, the person(s) named in the will as executor(s) apply for a Grant of Probate. The Grant confirms their authority to deal with the estate. If there is no will (intestacy), or if the named executors cannot or will not act, the next of kin can apply to be administrator(s), receiving Letters of Administration instead. The process is similar, but intestacy rules — not the will — determine how the estate is distributed.

Executors and administrators have a personal liability for correctly valuing the estate and paying IHT. If they distribute the estate before paying IHT, and HMRC later raises an assessment, the executor may be personally liable. HMRC also requires the IHT account (IHT400 for taxable estates) to be submitted before the probate application is processed — you cannot obtain the Grant without HMRC's confirmation of the IHT position.

Probate Registry Fees 2026

The Probate Registry (part of HMCTS) charges a fee for issuing the Grant of Probate: currently £300 for estates over £5,000, regardless of estate size. Up to £5,000, no fee is payable. Additional certified copies of the Grant cost £1.50 each — useful for estates with multiple banks, financial institutions, or property registrations. The previous fee structure (where fees scaled with estate size) was proposed but never implemented.

Probate solicitor fees vary widely: simple estates handled professionally typically cost £1,500–£4,000; complex estates with multiple properties, business interests, or tax planning can cost £5,000–£20,000+. Some solicitors charge a percentage of the estate value (typically 1–2%), which can be expensive for large estates. Executors can handle probate themselves for straightforward estates — particularly important when IHT is not payable and the estate consists mainly of cash and straightforward financial accounts.
