Can You Change a Will After Death UK (2026)? What the Law Allows

No — a will cannot be changed after the testator (the person who made the will) has died. Once the testator dies: (1) The will is fixed: the will in its final executed form is the document that governs the distribution of the estate. No one — not the executor, not the beneficiaries, not the family — can alter the will document itself after death. Any annotation, crossing out, or addition made to the will after the testator's death is legally ineffective and may actually raise questions about the will's authenticity; (2) The will is admitted to probate in its existing form: when the executor applies for a Grant of Probate, the Probate Registry admits the will as presented. The will then becomes a public document available to anyone. The contents cannot be changed at this stage; (3) After probate, the will is public: once probate is granted, anyone can search the Probate Registry (probate.service.gov.uk/search) and obtain a copy of the will. The document is permanent and public; (4) However, beneficiaries can redirect their own inheritance: although the will itself cannot be changed, the people who benefit under it can voluntarily agree to redirect their own entitlements. This is different from changing the will — it is a new legal arrangement made between the beneficiaries themselves. The most common mechanisms are: (a) Deed of variation (IHTA 1984 s.142): the most powerful tool — allows beneficiaries to redirect their inheritance to different people and, if done within 2 years of death, obtains IHT and CGT advantages by treating the variation as if the deceased had made it; (b) Disclaimer of inheritance: a beneficiary can renounce their entire entitlement — they cannot disclaim part; (c) Discretionary trust distribution: if the will created a discretionary trust, the trustees can exercise their discretion to vary who benefits; (5) Court rectification (not a post-death change): in limited circumstances, a court can rectify a will that failed to give effect to the testator's intentions due to a clerical error or failure to understand their instructions (AJA 1982 s.20). This is a court correction of the document, not a change by the parties.

A deed of variation (sometimes called a family arrangement) is a legal document signed by beneficiaries to redirect their inheritance after a death: (1) What it does: a deed of variation changes who receives specific assets from the estate — for example, an adult child can redirect their £200,000 inheritance to their own children (the deceased's grandchildren), or to a charity, or to their sibling; (2) Key tax advantage (the 's.142 read-back'): if the deed is executed within 2 years of the date of death and includes the required IHTA 1984 s.142 election statement, the variation is treated for IHT purposes as if the deceased had made those arrangements at death. This means: (a) a gift to a surviving spouse becomes IHT-exempt (the IHTA 1984 s.18 spouse exemption applies to the varied gift as if the deceased had left it to the spouse); (b) a gift to charity becomes IHT-exempt; (c) the redirected inheritance does NOT start a new 7-year PET clock for the beneficiary who gives it up; (d) the new beneficiary's CGT base cost is the probate value (if a TCGA 1992 s.62(7) election is also included); (3) Who must sign: all beneficiaries whose entitlement is reduced; the personal representative must sign if the variation increases IHT; (4) 2-year time limit: the deed must be executed within 2 years of the date of death. There is no HMRC discretion to extend this deadline; (5) Practical uses: (a) surviving spouse redirects inheritance to maximise NRB and RNRB efficiency; (b) adult children redirect inheritance skipping a generation to grandchildren; (c) redirecting to charity to use the 10% charitable legacy IHT reduction (where applicable); (d) fixing a will that was not tax-efficient because circumstances changed between writing and death; (e) simplifying the estate — avoiding a trust set up in the will by redirecting assets outright.

A disclaimer is a different mechanism that allows a beneficiary to refuse their entire entitlement under a will or the intestacy rules: (1) What a disclaimer is: a disclaimer is a formal refusal by a beneficiary to accept their inheritance. Once disclaimed, the beneficiary is treated as having predeceased the testator — their share passes to whoever would be next entitled under the will (the gift's substitute provision) or the intestacy rules; (2) Key difference from a deed of variation: (a) disclaimer = renouncing the entire gift or share; you cannot disclaim part of a gift or pick and choose which assets to disclaim; (b) deed of variation = actively redirecting the inheritance to a specific new beneficiary of your choice; (c) if you disclaim, you have no control over where the assets go — they pass to whoever is next in line under the will or intestacy; if you deed of variation, you choose the new recipient; (3) Tax treatment: a valid disclaimer also obtains the s.142 read-back: the estate is administered as if the disclaiming beneficiary had predeceased the deceased. No new PET clock starts. However, a disclaimer can only redirect to whoever is next entitled — you cannot use a disclaimer to benefit a specific person of your choice; (4) When a disclaimer is useful: (a) when the beneficiary is already very wealthy and wants to pass assets directly to the next generation without any choice over who receives them; (b) when the beneficiary is on means-tested benefits and receiving the inheritance would affect their entitlement — a disclaimer removes the receipt entirely (a deed of variation from beneficiary to themselves as bare trustee would not avoid the notional capital rules); (c) when speed is important — a disclaimer can be executed quickly without needing to know the exact value of assets; (5) 2-year time limit: disclaimers also attract the s.142 read-back only if made within 2 years of death. A disclaimer outside 2 years is effective but treated as a gift from the beneficiary; (6) No disclaimer after acceptance: a beneficiary cannot disclaim an inheritance they have already accepted (even impliedly, e.g., by receiving dividend income or exercising shareholder rights). Act quickly.

An executor's role is to carry out the instructions in the will — they have no power to change the distribution unless: (1) The will gives them discretion: some wills create discretionary trusts or give the executor specific powers to make decisions about who benefits. Where the will creates a discretionary trust, the trustees (who are often the same people as the executors) exercise genuine discretion over distributions. This is authorised by the will itself, not a change to it; (2) All adult beneficiaries with full capacity agree: under the rule in Saunders v Vautier [1841], if ALL beneficiaries are adult, have full mental capacity, and are collectively entitled to the entire beneficial interest of the trust or estate, they can together direct the trustees/executor to do whatever they wish with the assets — including departing from the will's instructions. This is a unanimous beneficiary override, not a unilateral executor decision. The executor cannot act alone; (3) Court order: a court can order the estate to be administered differently in certain circumstances — for example, under the Variation of Trusts Act 1958 (varying existing trusts for tax or other reasons), or under the Inheritance (Provision for Family and Dependants) Act 1975 (where the court provides for dependants not adequately provided for); (4) Court rectification (AJA 1982 s.20): if a will failed to give effect to the testator's intention due to a clerical error or a misunderstanding of instructions, the court can rectify the will. The application must be made within 6 months of probate (unless the court grants an extension); (5) What an executor cannot do alone: an executor cannot: redistribute assets contrary to the will's terms without all beneficiaries' consent; sell estate property for undervalue to a connected party; delay administration unreasonably; ignore the will's instructions. Doing so constitutes devastavit — the executor is personally liable for any loss caused to the estate.

Challenging a will (contentious probate) is distinct from varying it — a challenge seeks to have the will declared invalid, not to redirect the inheritance. The main grounds are: (1) Lack of testamentary capacity (Banks v Goodfellow [1870] criteria): the testator must have understood: (a) the nature of making a will and its effects; (b) the extent of the property they were disposing of; (c) the claims of those who might reasonably expect to benefit; (d) must not have been suffering from any disorder of the mind that poisoned their affections, perverted their sense of right, or prevented the exercise of natural faculties. Dementia or other cognitive conditions can raise capacity questions; (2) Lack of knowledge and approval: even with capacity, the testator must have known and approved the contents of the will. Unusual circumstances (the testator was blind or illiterate; the will was signed in hospital) can raise this issue; (3) Undue influence: the testator's free will was overborne by another person's pressure. Undue influence is notoriously difficult to prove — the courts require evidence of coercion going beyond persuasion or advice; (4) Fraud or forgery: the will was forged or the testator was deceived into signing it; (5) Execution defects: the will was not properly signed or witnessed as required by the Wills Act 1837 (two independent witnesses present at the same time, signing in the testator's presence); (6) Rectification: the will does not reflect the testator's instructions due to a clerical error or the solicitor's misunderstanding (AJA 1982 s.20 — apply within 6 months of probate); (7) Time limits: challenges must be made promptly. The court can refuse to hear a challenge where unreasonable delay has caused prejudice to the estate. A caveat at the Probate Registry prevents the Grant being issued while a challenge is being investigated.
