A deed of variation is a written arrangement that lets someone who inherits under a will or the intestacy rules give up or redirect all or part of that inheritance to another person. Where it is made within two years of the death and meets the statutory conditions, it can be read back for tax as though the deceased had left the assets that way (gov.uk, change a will after a death, as at July 2026, subject to change).
It does not rewrite the will itself. The original will stands, but a beneficiary chooses to pass on what they were due to receive. This guide explains when a variation can be used, the conditions it must meet, and how it interacts with tax. It sits alongside our estate planning guide and our note on What Is Probate?. Figures are current as at July 2026 and are subject to change.
What is a deed of variation?
A deed of variation is a document by which a beneficiary of an estate redirects some or all of their entitlement to a different person. It can apply where there is a will or where the estate passes under the intestacy rules. The original will is not changed; instead the beneficiary who gives something up directs where it goes, and the tax rules can treat that redirection as if it came from the deceased (gov.uk, as at July 2026, subject to change).
Why do people use a deed of variation?
People use variations for several reasons, not only tax. A common one is to pass an inheritance down a generation to children or grandchildren who need it more. Others include providing for someone the will left out, moving assets into a trust, resolving a dispute, or directing a gift to charity. Each has different consequences, so many people take advice before signing.
- Passing it on. An adult child may redirect part of their inheritance to their own children.
- Fairness. Beneficiaries may even out an estate the will divided unequally, by agreement.
- Someone left out. A variation can provide for a person the will did not mention.
- Tax. Redirecting a gift may change the inheritance tax or capital gains tax outcome, depending on circumstances.
- Charity. Directing at least part of an estate to charity can change the rate that applies to the rest.
The conditions a variation must meet
For a variation to be read back for tax, it has to meet specific conditions. It must be in writing, made within two years of the death, and signed by everyone giving up a benefit. It must not be made in exchange for money or anything of value, and where it is meant to change the tax position it needs to state that the parties intend it to take effect for inheritance tax, capital gains tax, or both (gov.uk, instrument of variation checklist IOV2, as at July 2026, subject to change).
| Condition | What it means |
|---|---|
| In writing | A signed document, or a letter that meets the same conditions. |
| Within two years | Made within two years of the date of death. |
| Consent | Signed by anyone left worse off by the change. |
| No consideration | Not made in return for money or money's worth. |
| Tax statement | States it is intended to take effect for IHT and/or CGT, where relevant. |
