Deed of Variation UK: What It Is and How to Use It to Protect Your Inheritance

You've inherited something. Maybe it's money, maybe it's property, maybe it's a share of an estate that came to you unexpectedly. And now you're sitting with a question most people don't know is even possible: can I do something different with this?

The answer, in many cases, is yes. That's what a deed of variation is for.

This guide explains exactly what it is, how it works, and how families across the UK use it to redirect inherited assets — reducing inheritance tax, protecting wealth, and building the kind of structure that lasts beyond one generation.

What is a deed of variation?

A deed of variation (also called a deed of family arrangement) is a legal document that allows a beneficiary to redirect their inherited assets — either to another person, or into a trust — within two years of the deceased's death. When executed correctly and accompanied by the appropriate HMRC election, the variation is treated as if it had been written into the original will by the deceased themselves. This backdating effect is what makes a deed of variation such a powerful tool for inheritance tax planning — the redirected assets are assessed at the deceased's estate level, not in the hands of the beneficiary who received them.

In plain terms: you can legally change what happens to an inheritance after the fact, and in many cases HMRC will treat it as if you never received it at all.

How does a deed of variation work?

The process follows a clear sequence:

Step 1 — You receive an inheritance. You are named as a beneficiary under a will, or you inherit under intestacy rules (the default rules that apply when someone dies without a will). Either way, assets pass to you as a matter of law.

Step 2 — You decide to redirect some or all of it. Perhaps you want to pass your share directly to your children. Perhaps you want to move it into a family trust. Perhaps you want to redirect it to a spouse or charity for tax reasons. A deed of variation makes this possible.

Step 3 — You execute the deed within two years of the date of death. This is the critical window. The two-year limit is fixed — there are no extensions. All beneficiaries who are affected by the redirection must agree to the variation and sign the deed. If the change has inheritance tax or capital gains tax consequences, the deed must include a written election and HMRC must be notified.

Step 4 — HMRC treats the variation as if it was in the original will. This is the backdating effect. For tax purposes, it is as if the deceased left their estate exactly as the deed describes — not as the original will said. The beneficiary who redirected their inheritance is not treated as having made a gift from their own assets.

The two-year window is worth taking seriously. Estates can take time to administer — particularly when going through probate — and families sometimes discover the opportunity too late. If you think a deed of variation might be relevant to your situation, raise it early.

What are the inheritance tax benefits of a deed of variation?

This is the main reason most families use a deed of variation, and the benefits can be substantial.

Redirecting to a spouse or civil partner. Assets that pass between spouses and civil partners are entirely exempt from inheritance tax. If you inherit from a parent's estate and redirect your share to your surviving parent, that redirected amount is IHT-free. It also means the surviving parent's nil-rate band is preserved for the next generation.

Redirecting into a trust. Moving inherited assets into a family discretionary trust is one of the most effective uses of a deed of variation. Assets held in a will trust can sit outside the beneficiary's estate immediately — unlike lifetime gifts, which require the donor to survive seven years before falling outside their estate for IHT purposes. We cover this in more detail in the section below.

Redirecting to charity. Gifts to registered charities are IHT-exempt. If an estate is just above the nil-rate band threshold, redirecting part of the inheritance to charity can bring the taxable estate below the threshold entirely. And if 10% or more of the net estate goes to charity, the IHT rate on the remainder drops from 40% to 36%.

Using the nil-rate band more efficiently. The current nil-rate band is £325,000 per person, with a residence nil-rate band of up to £175,000 where a qualifying residential property passes to direct descendants. A deed of variation can sometimes be used to restructure an estate so these allowances are used more effectively — for example, ensuring a parent's unused nil-rate band is properly preserved and transferred.

Who can use a deed of variation?

Any beneficiary of a will — or anyone who inherits under the intestacy rules — can execute a deed of variation. You do not need to be the executor, and you do not need the estate to have been administered first (though in practice it helps to know what you're working with).

The key rules:

• The variation must be made within two years of the date of death. No exceptions.
• It must be in writing. A verbal agreement is not sufficient.
• All beneficiaries who are giving up or reducing their share must consent. If you are simply redirecting your own inheritance without touching anyone else's share, you can act alone. If the redirection reduces another beneficiary's entitlement, they must agree in writing.
• HMRC must be notified if the variation affects IHT or CGT. The deed must include the relevant election, and it must be sent to HMRC.
• Children under 18 cannot legally consent. If a minor's share is being reduced, the court's approval may be required — this adds complexity and time.

Can a deed of variation redirect assets into a trust?

Yes — and this is where the planning becomes genuinely powerful.

When you use a deed of variation to redirect inherited assets into a family discretionary trust, those assets are treated as if they passed into the trust under the deceased's will. This is significant because will trusts are treated differently from lifetime trusts for IHT purposes: assets in a will trust can sit outside the beneficiary's estate immediately, without the seven-year survival period that applies to lifetime gifts.

What that means in practice:

• Assets held in the trust are outside your estate for IHT purposes. If you were to inherit and keep the money personally, it would sit in your estate and be subject to 40% IHT on your death. Inside a trust, it is ring-fenced.
• Trustees manage distributions. Rather than a lump sum passing directly to individuals, trustees can distribute income and capital over time — to children, grandchildren, and beyond — according to the family's needs.
• Assets are protected from divorce and creditors. Because the assets are held by trustees rather than individuals, they are harder to reach in a divorce settlement or insolvency.

For families thinking about how to set up a family discretionary trust, a deed of variation can be the mechanism that funds that trust — using inherited wealth rather than assets you've already accumulated.

One important caveat: if the amount redirected into a discretionary trust exceeds the nil-rate band (currently £325,000), a Chargeable Lifetime Transfer may arise, with IHT payable at 20% on the excess. For larger estates, professional planning advice is important.

Once the trust is established, it will need to be registered with the Trust Registration Service — a straightforward but important step.

What are the risks and limitations?

A deed of variation is a powerful tool, but it's not without complexity.

All affected beneficiaries must agree. Family dynamics can make this difficult. If one beneficiary refuses to sign — perhaps they need the money, or there's existing conflict — the variation cannot proceed. This is a genuine risk in estates involving estranged family members or disputes about the will.

It doesn't work after two years. The two-year window is absolute. Families who discover the option too late — perhaps because the estate took a long time to administer — cannot use it. If you are writing your will, it's worth flagging the option to your beneficiaries so they're aware of it from the start.

Children under 18 cannot consent. If a minor's entitlement is being varied, the court may need to be involved. This adds time, cost, and complexity — and is not always successful.

A Chargeable Lifetime Transfer may arise. As noted above, redirecting more than the nil-rate band into a discretionary trust has tax consequences. This needs careful planning before execution.

It is irrevocable. Once a deed of variation has been executed and an HMRC election made, it cannot be undone. The decision needs to be right the first time.

Does a deed of variation need to go to a solicitor?

For complex estates — large sums, multiple beneficiaries, assets going into a trust, or potential Chargeable Lifetime Transfers — the answer is strongly yes. The stakes are high, the rules are specific, and errors can be costly.

For simpler redirections — for example, redirecting a modest inheritance to a child where there are no competing beneficiaries and no significant tax consequences — a well-drafted document is the starting point. Many families use a specialist document preparation service to produce the framework, then take it to a solicitor for a final check before execution.

The key is not to try to navigate it alone without any proper documentation. A deed of variation is a legal document — it needs to be in writing, properly structured, and signed by the right parties. A verbal arrangement, even among family members, has no legal effect.
