Residuary Estate UK (2026): What It Is, How It Is Calculated and Who Inherits the Residue

The residuary estate is what remains of the deceased's estate once everything else has been dealt with. It is calculated by taking the total estate value and deducting in this order: (1) WHAT IS DEDUCTED BEFORE THE RESIDUE IS ARRIVED AT: (a) all funeral expenses (reasonable funeral and burial or cremation costs; costs of a memorial); (b) testamentary expenses (costs of obtaining probate; executor's fees if the will or TA 2000 authorises charging; estate agent and solicitor fees for selling property; HMRC correspondence costs); (c) all debts owed by the deceased at the date of death (mortgage balance; unsecured debts; credit cards; personal loans; utility arrears; HMRC income tax liability to date of death); (d) inheritance tax (IHT payable on the estate — unless specific legacies are expressly stated to be 'subject to tax' in which case the beneficiary bears their own IHT); (e) all specific legacies — specific items named in the will ('my signed first edition to my nephew'; 'my car to my daughter'; 'the property at 12 Oak Road to my son'); (f) all pecuniary legacies — cash gifts named in the will ('£5,000 to my sister'; '£10,000 to my god-daughter'); (2) WHAT REMAINS IS THE RESIDUE: once all the above have been dealt with, what is left — the residue — passes to the residuary beneficiary or beneficiaries in whatever shares the will specifies. In many wills, the residuary clause is the most important: it captures everything that has not been specifically disposed of — unnamed bank accounts; investments opened after the will was made; cash; debts owed to the deceased; anything else; (3) THE RESIDUARY CLAUSE: a well-drafted will always includes a residuary clause. Typical examples: 'I give the whole of the rest and residue of my estate to my spouse absolutely'; 'I give the rest and residue of my estate to my children in equal shares per stirpes'; 'I give the rest and residue to my trustees to hold on the trusts set out in Clause X'; (4) WHAT HAPPENS WITHOUT A RESIDUARY CLAUSE: any property not specifically disposed of by the will falls into partial intestacy. The intestacy rules (AEA 1925 s.46) apply to that undisposed portion — the residue passes under the intestacy rules, not under the will. This may produce a completely different result from what the testator intended; (5) CALCULATING THE RESIDUE IN PRACTICE: for a simple estate — cash in bank accounts (£120,000) + investments (£80,000) + property (£350,000) - mortgage (£100,000) - debts (£5,000) - funeral and expenses (£8,000) - IHT (£55,000 if no exemptions) - pecuniary legacies (£20,000) = residue of approximately £362,000.

Abatement is the process by which legacies are reduced when the estate is insufficient to pay all of them in full. The order of abatement is set by statute (AEA 1925 s.34 and First Schedule): (1) THE GENERAL PRINCIPLE: debts and expenses are paid first (in the priority order set out in the First Schedule to the AEA 1925). Once debts are fully satisfied, what remains is distributed. If there is not enough to pay debts AND legacies, the legacies must abate; (2) THE ORDER OF ABATEMENT FOR LEGACIES: (a) RESIDUE ABATES FIRST: the residuary estate is the first casualty — the residuary beneficiary bears all shortfall before specific or pecuniary legatees are affected. The testator's chosen residuary beneficiary receives whatever is left after everything else is paid; (b) GENERAL (PECUNIARY) LEGACIES ABATE NEXT: if the residue is exhausted, general legacies (cash gifts of £x to named persons) abate proportionately among themselves — each pecuniary legatee receives a ratable proportion of their gift; (c) DEMONSTRATIVE LEGACIES: these are legacies payable out of a specific fund (e.g. '£5,000 from my Barclays account'). They abate after general legacies but before specific legacies as to the general estate, and after specific legacies as to the specified fund; (d) SPECIFIC LEGACIES ABATE LAST: specific legacies (named items) are the most protected. They are only reduced after all other legacies have been extinguished. Partial abatement of specific legacies is rare; (3) EXAMPLE — ABATEMENT IN PRACTICE: the estate is worth £100,000 after debts and expenses. The will includes: pecuniary legacy of £80,000 to friend A; pecuniary legacy of £40,000 to friend B; residue to daughter. Total pecuniary legacies = £120,000 — exceeds the estate. Residue = nil (absorbed by the shortfall). Friends A and B share the £100,000 pro rata: A gets £80,000/£120,000 × £100,000 = £66,667; B gets £40,000/£120,000 × £100,000 = £33,333. Daughter receives nothing; (4) LEGACY CHARGED WITH IHT: where a specific legacy is stated to be 'subject to tax' or 'net of tax' or where the will specifically charges the IHT to the beneficiary, the abatement calculation must reflect the IHT liability borne by that legacy. In most wills, specific and pecuniary legacies are given 'free of tax' — the IHT is borne by the residue; (5) NOTIONAL ESTATE: if the IHT account includes notional estate (e.g. IHTA 1984 s.103 — post-death variation; or s.142 — deed of variation redirecting gifts from the estate), the abatement calculation must account for the notional estate values correctly.

A residuary gift lapses (fails) when the residuary beneficiary predeceases the testator. The consequences depend on whether the residue is a gift to a single person, shared among multiple people, or whether there is a substitution clause: (1) LAPSE OF A SOLE RESIDUARY GIFT: if the will gives the entire residue to one person who predeceases the testator and there is no substitution clause, the residue falls into total intestacy. The whole estate (or at least the residue) passes under the AEA 1925 intestacy rules — regardless of what the rest of the will says; (2) LAPSE OF A SHARE OF RESIDUE: if the residue is given 'to my children in equal shares' and one child predeceases, their share of the residue may lapse and fall into partial intestacy (passing to the testator's surviving spouse and/or other children under the intestacy rules) — unless one of the saving mechanisms applies; (3) WILLS ACT 1837 s.33 — ANTI-LAPSE FOR CHILDREN: section 33 of the Wills Act 1837 saves a gift to a child (or remoter issue) of the testator where that child predeceases but leaves issue of their own who survive the testator. EXAMPLE: will gives residue 'to my children'. Testator's daughter predeceases but leaves two grandchildren who survive the testator. S.33 saves the gift — the daughter's share passes to her children (the grandchildren). S.33 does NOT apply to gifts to non-issue beneficiaries (e.g. siblings, cousins, friends); (4) SUBSTITUTION CLAUSES: a well-drafted will includes an explicit substitution clause: 'If any of my children predecease me, their share shall pass to their children in equal shares per stirpes'. This does what s.33 does but more explicitly and can be drafted to cover any beneficiary (not just issue); (5) THE SURVIVORSHIP CLAUSE INTERACTION: where the will contains a survivorship clause (requiring the beneficiary to survive by 30 days), a beneficiary who dies within 30 days of the testator is NOT a predecease — s.33 does NOT save that person's gift because they technically survived the testator (for an instant). The survivorship clause makes s.33 irrelevant for short-survival deaths. Always pair a survivorship clause with an explicit substitution clause to address both scenarios; (6) CLASS GIFTS: a gift 'to my children' is a class gift — the class closes to those who qualify on the testator's death. If one member of the class predeceases, the remaining members of the class each take a larger share rather than the gift lapsing (unless the gift is specifically stated to be to 'equal shares' which may fix the proportions).

The default position is that IHT is paid from the residuary estate, but this can be varied by the will: (1) THE DEFAULT RULE — IHT FALLS ON THE RESIDUE: under IHTA 1984 s.211, the IHT attributable to property in the UK which vests in the personal representatives is a testamentary expense — it is paid from the estate before the residue is ascertained. In practice: specific legacies are handed over to the beneficiary 'free of IHT' — the IHT on those items is charged against the residue. Pecuniary legacies are also generally free of IHT. The residuary beneficiary therefore bears the full IHT cost. This can dramatically reduce the residue where the estate has a large IHT liability; (2) GROSSING UP: where the will gives specific or pecuniary legacies 'free of tax', and the estate as a whole is subject to IHT, the legacies must be 'grossed up' to determine the true IHT charge. This is because the IHT-free legacy is in effect increasing the gross estate. EXAMPLE: estate of £1 million; NRB = £325,000; IHT on excess = £270,000 (at 40%). If there is a £100,000 legacy to a friend (free of tax), the IHT must be calculated on a grossed-up value. HMRC guidance and IHTM provides the grossing-up formula; (3) 'SUBJECT TO TAX' LEGACIES: if the will expressly says a legacy is 'subject to tax' or 'the beneficiary shall pay the IHT attributable to this gift', the legatee bears their own IHT. This relieves the residue and increases the net amount available for the residuary beneficiary; (4) THE INSTALMENT OPTION: IHT on property (land and buildings) and business or agricultural assets can be paid in 10 equal annual instalments (IHTA 1984 s.227). This does not reduce the IHT payable — it just defers cash flow. Interest accrues on outstanding instalments. The property cannot be sold (or if sold, the remaining instalments become due immediately) without paying off the outstanding IHT; (5) IHT ON EXEMPT GIFTS: gifts to a surviving spouse (IHTA 1984 s.18) and gifts to charity (IHTA 1984 s.23) are IHT-exempt and no IHT is charged on those portions. The residue is reduced by these exempt amounts before IHT is calculated on the remainder. Where 10% or more of the estate passes to charity, the effective IHT rate reduces to 36% on the taxable estate (IHTA 1984 s.24A).

Partial intestacy occurs where a person dies leaving a valid will but the will does not dispose of all the estate. The undisposed portion passes under the intestacy rules: (1) WHEN PARTIAL INTESTACY ARISES: (a) no residuary clause: the will contains only specific and/or pecuniary legacies but no residuary clause. Anything not specifically mentioned falls into partial intestacy; (b) lapse of the residuary gift: the sole residuary beneficiary predeceases the testator and there is no substitution clause and s.33 does not save the gift. The whole residue falls into intestacy; (c) share of residue lapses: where the residue is given to named beneficiaries and one or more predecease without s.33 saving the gift, their share falls into partial intestacy; (d) void gift: a gift to an attesting witness is void (WA 1837 s.15 — the witness forfeits the gift); the voided portion falls into partial intestacy; (2) THE CONSEQUENCES OF PARTIAL INTESTACY: the portion that falls into partial intestacy is distributed under AEA 1925 s.46 as if the testator had died intestate for that portion. This means: if the deceased left a spouse, the spouse takes the statutory legacy (£322,000 from 26 July 2023 — updated periodically) plus half the remainder; children take the other half on statutory trusts; if no spouse/CP — children take the whole partial intestacy; if no issue — parents; if no parents — siblings; etc. This result will often be different from what the testator intended; (3) PRACTICAL EXAMPLE: a will gives a specific gift of a watch and £5,000 cash to a friend, but has no residuary clause. The £300,000 house and £150,000 savings fall into partial intestacy and are distributed under the intestacy rules — which may pass them to distant relatives or the Crown (bona vacantia) if there are no close family; (4) THE DRAFTING FIX: every will should include a residuary clause. Even a simple clause ('I give the rest and residue of my estate to X absolutely, and if X shall predecease me to Y absolutely') protects the testator's wishes for virtually all circumstances. Without it, the testator is relying on the intestacy rules to produce the desired result — which is almost never the right outcome.
