Disclaimer vs Deed of Variation UK (2026): How to Refuse or Redirect an Inheritance

Both tools allow a beneficiary to change what happens to an inheritance after the testator has died, but they work in fundamentally different ways: (1) DISCLAIMER: a disclaimer is the outright REFUSAL of a legacy before it has been accepted. The disclaiming beneficiary simply says 'I don't want this.' The asset falls back into the estate — to the residue (if it was a specific or pecuniary gift) or to intestacy (if the residue itself is disclaimed). Critically, the disclaimant CANNOT choose where the asset goes — they can only give it up. They cannot redirect it to their own children, their spouse, or anyone else by way of a disclaimer; (2) DEED OF VARIATION: a deed of variation allows the beneficiary to REDIRECT the inherited asset to a specific third party of their choosing. The beneficiary who inherited can direct the asset to their children, to charity, into a trust, or to any named person. The key distinction from a disclaimer is that the beneficiary is in control of where it goes; (3) WHEN TO USE A DISCLAIMER: (a) when the beneficiary simply does not want the asset and is content for it to fall into residue (to benefit other residuary beneficiaries); (b) where the asset is a burden (a loss-making business, a property with environmental liabilities, an overencumbered estate); (c) where the legal formalities of a deed of variation are not practicable; (4) WHEN TO USE A DEED OF VARIATION: (a) when the beneficiary wants to redirect the asset to a specific person (their children, a charity, another family member); (b) when the asset should skip a generation (generation skipping — giving directly to grandchildren to avoid double IHT); (c) when the original will did not achieve the intended IHT outcome and a variation can correct it; (d) when assets should pass to a surviving spouse or civil partner rather than adult children, to use the spouse exemption and defer IHT; (5) THE CRITICAL POINT: once an asset has been ACCEPTED (income received, property occupied, capital drawn), a disclaimer is no longer possible. The beneficiary must execute a deed of variation instead.

A deed of variation that is to be effective for IHT (and CGT) purposes must comply strictly with IHTA 1984 s.142: (1) IN WRITING: the variation must be in writing — it cannot be made orally. In practice, it is executed as a deed (with witness and delivery), though HMRC has accepted letters in some circumstances. A formal deed is strongly advisable; (2) SIGNED BY THE PERSONS MAKING THE VARIATION: all persons who are adversely affected by the variation (i.e. those who would otherwise receive the assets being redirected) must sign. If the residue is being varied to redirect part away from a residuary beneficiary, that beneficiary must sign; (3) WITHIN 2 YEARS OF DEATH: the variation must be executed within 2 years of the testator's death (IHTA s.142(1)). There is no power to extend this period. An estate that takes 3 years to administer may still be varied — but the 2-year clock runs from the date of death, not the date of the grant; (4) NO CONSIDERATION: no consideration must pass for the variation — it must be gratuitous. If a cash payment or other benefit is given in exchange for the variation, the statutory treatment under s.142 is lost. The variation is then treated as a disposition by the original beneficiary — subject to PET or CLT rules; (5) THE IHTA ELECTION (STATUTORY STATEMENT): the deed must contain an express written statement that s.142(1) IHTA 1984 is to apply. Without this statement, the variation is treated as a gift by the original beneficiary (a potentially exempt transfer or chargeable lifetime transfer) — NOT as if made by the deceased. The statement need not be in any specific form but is typically: 'The parties to this deed of variation confirm that the provisions of section 142(1) Inheritance Tax Act 1984 shall apply to this variation'; (6) NOTIFICATION TO HMRC: if the variation results in more IHT being payable, HMRC must be notified within 6 months of the variation. If the variation reduces IHT, HMRC will repay the overpaid tax or adjust the liability; (7) CGT ELECTION (TCGA 1992 s.62(6)): a separate election must be included in the deed if the parties wish the variation also to be treated as made by the deceased for CGT purposes. Without this, any gain from date of death to date of variation is a disposal by the original beneficiary; (8) MINORS AND CHARITIES: if the variation reduces the share of a minor beneficiary, the court's approval is needed (Variation of Trusts Act 1958). If the original will or intestacy benefits a charity, the charity commissioners' consent may be required.

A disclaimer can be effective for IHT purposes under IHTA 1984 s.142 — but the mechanics are different from a deed of variation: (1) IHT EFFECT OF DISCLAIMER (IHTA s.142(1)(a)): a disclaimer made within 2 years of death is treated as if the disclaimed property had never passed to the disclaimant for IHT purposes. HMRC treats the property as passing directly under the original rules of the will or intestacy to whoever receives it after the disclaimer (the next person in line under the will or intestacy rules); (2) WHERE THE DISCLAIMED ASSET GOES: (a) specific or pecuniary legacy disclaimed: falls into the residue of the estate; (b) residuary gift disclaimed: the disclaimed portion of residue passes on intestacy (unless the will provides for alternative residuary beneficiaries); (c) intestacy share disclaimed: the disclaimed share is redistributed according to the intestacy rules as if the disclaimant had predeceased — so it goes to the disclaimant's own issue (if any), not necessarily to the other siblings; (3) FORMALITIES FOR AN EFFECTIVE DISCLAIMER: (a) in writing (IHTA s.142 requires written disclaimer for IHT relief); (b) must contain a statement that IHTA s.142 is to apply (same as a deed of variation); (c) within 2 years of death; (d) not after acceptance of any benefit from the disclaimed asset; (4) CANNOT DISCLAIM PART: a beneficiary cannot disclaim part of a single legacy — they must disclaim the whole. However, if the will makes several distinct gifts, each can be disclaimed separately; (5) COMMON USE CASE: an adult beneficiary is personally solvent but their inheritance would be at risk from creditors (personal insolvency) or from claims under the Inheritance Act 1975. Disclaiming before formal acceptance removes the asset from their estate — though insolvency law (IA 1986 s.342) allows trustees in bankruptcy to set aside a disclaimer made within 2 years of the bankruptcy if the effect was to defraud creditors; (6) CONTRAST WITH DEED OF VARIATION: if the beneficiary wants the asset to go to their own children (rather than back into residue), a deed of variation is needed — not a disclaimer.

Deeds of variation are one of the most powerful post-death IHT planning tools available under English law, precisely because IHTA s.142 treats the variation as made by the deceased: (1) GENERATION SKIPPING: the most common use. A parent inherits from a grandparent and immediately varies the gift in favour of their own children (the deceased's grandchildren). This avoids the parent's estate being swollen by the inheritance — avoiding double IHT (once in the parent's estate). The variation is treated as if the grandparent had given directly to the grandchildren; (2) CHARITABLE GIFT FOR 36% RATE (IHTA s.24A): if the original will left less than 10% of the net estate to charity, a deed of variation can add a charitable legacy to reach the 10% threshold — triggering the reduced 36% IHT rate on the entire remaining estate. The saving can be significant where the taxable estate is large; (3) REDIRECTING TO A SPOUSE FOR SPOUSE EXEMPTION: where the will left a large sum to adult children (40% IHT payable), a deed of variation can redirect to the surviving spouse — using the unlimited spouse exemption to defer the IHT until the survivor's death. The children become beneficiaries of the survivor's will instead; (4) EQUALISING ESTATES: where one spouse has a disproportionately large estate, a variation can redirect assets from the well-off spouse's will to the other, reducing the higher estate and making better use of both NRBs; (5) CREATING A TRUST: a variation can create a trust that the original will did not — for example, a discretionary trust for minor grandchildren, or a life interest trust for a surviving cohabitant who was excluded from the will; (6) USING THE DECEASED'S UNUSED NRB: if the estate passed entirely to a spouse (exempt), the NRB was preserved via TNRB — but a variation can introduce a specific NRB gift to adult children at the first death, using the NRB and leaving the TNRB available for the survivor's estate; (7) CORRECTING MISTAKES: where the will contained a drafting error, or the testator's circumstances changed after the will was made, a deed of variation can correct the distribution to what was intended.

Deeds of variation are a powerful tool but they are not unlimited — several restrictions apply: (1) NO SECOND VARIATION OF THE SAME ASSET: once a specific asset has been varied under IHTA s.142, that variation cannot itself be further varied (IHTA s.142(4)). The variation is treated as the final disposition. If the original variation was to A and A now wants to pass it to B, that is a new gift from A — a potentially exempt transfer, subject to the 7-year rule, not treated as made by the deceased; (2) MULTIPLE VARIATIONS ARE PERMITTED OF DIFFERENT ASSETS: in the same 2-year period, multiple variations can be made — provided each relates to a different asset or different share. The prohibition is on varying the same asset twice; (3) THE CONSIDERATION BAR: any form of consideration (cash, property, a promise to act) exchanged for the variation destroys the s.142 treatment. All variations must be gratuitous. Where multiple beneficiaries are rearranging their shares between themselves (cross-variations), HMRC scrutinises these to ensure no hidden consideration passes; (4) NO VARIATION AFTER ADMINISTRATION IS COMPLETE AND ASSETS DISTRIBUTED: once an asset has been distributed to the beneficiary and they have accepted it, a variation is still possible (unlike a disclaimer) — but the mechanics are different. The beneficiary must transfer the asset back or vary their interest; (5) HMRC WILL NOT RULE IN ADVANCE: HMRC does not provide advance clearance on whether a proposed deed of variation qualifies under s.142. The parties must structure it correctly and rely on settled case law and guidance; (6) CONSIDERATION IN PRACTICE — CROSS-VARIATIONS: if sibling A waives a gift in favour of sibling B, and sibling B simultaneously waives a different gift in favour of sibling A, HMRC may view this as disguised consideration. Each variation should be independently documented and free-standing; (7) THE 2-YEAR LONGSTOP: extensions are not possible even in exceptional circumstances. An estate with a disputed will, Court of Protection involvement, or complex international assets may struggle to execute a valid variation within 2 years. Professional advice should be sought early in the administration — not in the final months of the 2-year period.
