Deed of Variation: Can You Change a Will After Death? – Tax Implications in the UK

Dealing with the estate of a loved one can be a challenging and emotional process, particularly when the will doesn’t properly reflect the current needs of the family. Circumstances change — children grow up, marriages break down, tax laws shift — and the original will may no longer achieve what the deceased would have wanted. Fortunately, under English and Welsh law, beneficiaries have the option to alter how the estate is distributed after the person’s death through a legal instrument known as a deed of variation.

This flexibility can be particularly valuable for reducing inheritance tax (IHT) liabilities, providing for someone who was not included in the original will, or redirecting assets into a trust for vulnerable family members. We’ll explore exactly how a deed of variation works, who can use one, the strict time limits involved, and the tax implications you need to understand — ensuring that families can make informed decisions about their estate planning.

Key Takeaways

• Beneficiaries can redirect their inheritance after a person’s death using a deed of variation — but they can only vary their own entitlement, not someone else’s.
• Any beneficiary who is made worse off by the proposed changes must give their written consent.
• The deed must be executed within two years of the date of death to be treated as if the deceased had made the changes themselves for IHT and capital gains tax (CGT) purposes.
• A deed of variation can redirect assets to reduce IHT — for example, by passing assets to a spouse, charity, or into a discretionary trust.
• It can also be used to provide for someone left out of the original will, or to create a trust to protect vulnerable beneficiaries.

Understanding a Deed of Variation

A deed of variation is a legal document that enables beneficiaries to alter the terms of a will — or the rules governing intestacy — after a person’s death. In England and Wales, this provides a flexible post-death planning tool for beneficiaries who wish to modify how assets are distributed. Crucially, if properly drafted and executed within the two-year window, HMRC treats the variation as if the deceased had made the change themselves. This is what gives a deed of variation its powerful tax planning capability.

Definition of a Deed of Variation

A deed of variation (sometimes called a deed of family arrangement) is used to redirect assets that a beneficiary is entitled to receive under a will or under the intestacy rules. This can include changing who receives specific assets, redirecting a share of the estate to someone else entirely, or channelling assets into a trust. The deed must be signed by every beneficiary whose entitlement is reduced by the changes. It does not rewrite the will itself — rather, it redirects what the beneficiaries choose to do with their inheritance.

When is a Deed of Variation Used?

A deed of variation is commonly used when the original will no longer reflects the practical needs of the family, or where tax-saving opportunities have been missed. For instance, if the deceased left everything to their spouse, the entire estate passes IHT-free under the spousal exemption — but this may mean the nil rate band (currently £325,000 per person) goes unused, resulting in a larger IHT bill on the second death. A deed of variation can redirect some assets to children or into a discretionary trust, making use of the first spouse’s nil rate band.

Common situations where a deed of variation proves valuable include:

• Redirecting inheritance to a family member who was left out of the original will — perhaps a grandchild born after the will was written.
• Redirecting assets to a spouse or charity to reduce inheritance tax — gifts to spouses are exempt from IHT, and leaving 10% or more to charity can reduce the IHT rate from 40% to 36%.
• Creating a discretionary trust for vulnerable beneficiaries — for example, a child with a disability, a beneficiary with addiction issues, or a young adult who may not yet be ready to manage a large inheritance.

Eligibility Criteria for Making Changes

To make changes using a deed of variation, the individuals involved must be beneficiaries under the original will or under the intestacy rules. The deed requires the written consent of every beneficiary whose share is being reduced or redirected. A beneficiary can only vary their own entitlement — they cannot force changes on another beneficiary’s share without that person’s agreement.

There are several essential requirements to be aware of. The deed must be executed within two years of the date of death to be effective for IHT and CGT purposes. It must be in writing, and it must contain a specific statement that the variation is to be treated as made by the deceased for the purposes of inheritance tax (and/or CGT, if relevant). If the variation results in additional IHT becoming payable, the personal representatives (executors or administrators) must also give their written consent within six months of the deed being made. It is strongly advisable to seek specialist legal advice to ensure the deed is properly drafted and compliant — a poorly worded deed of variation can be challenged or may fail to achieve the intended tax treatment.

Legal Framework Surrounding Wills in the UK

The legal framework governing wills and estates in England and Wales is well-established, with specific legislation that dictates how estates are distributed. Understanding this framework is essential for making informed decisions about estate planning and the potential to modify how an estate is distributed after death.

Overview of Inheritance Laws

In England and Wales, if a person dies with a valid will, their estate is distributed according to its terms. If there is no will — known as dying intestate — the intestacy rules determine who inherits. These rules follow a strict hierarchy: spouse or civil partner first, then children, then other relatives. Under intestacy, unmarried partners, step-children, and friends receive nothing, regardless of the relationship’s closeness. A deed of variation can be used to redirect assets under either a will or the intestacy rules, provided it is executed within two years of the death.

Key legislation includes the Wills Act 1837 (governing how wills are made and revoked), the Administration of Estates Act 1925 (setting out the intestacy rules and the duties of personal representatives), and the Inheritance (Provision for Family and Dependants) Act 1975 (allowing eligible applicants to claim reasonable financial provision from an estate). The Inheritance and Trustees’ Powers Act 2014 modernised certain trustee powers and updated the intestacy rules.

The Role of Executors and Beneficiaries

Executors (or administrators, if there is no will) and beneficiaries play distinct but interconnected roles in estate administration. Executors are responsible for gathering the estate’s assets, paying any debts and taxes, obtaining the Grant of Probate, and distributing the estate according to the will. Beneficiaries are those who are entitled to receive assets from the estate.

• Executors have a fiduciary duty to act in the best interests of the estate and its beneficiaries — they cannot prefer one beneficiary over another.
• Beneficiaries have the right to receive their inheritance as outlined in the will or under the intestacy rules.
• Beneficiaries can agree to vary their entitlement through a deed of variation, redirecting their share to others, to charity, or into a trust.

Limitations on Amending Wills

While a deed of variation is a powerful planning tool, there are important limitations to understand. The deed must be executed within two years of the date of death. Only a beneficiary’s own entitlement can be varied — one beneficiary cannot alter another’s share without consent. If any beneficiary who would be worse off as a result of the variation is a minor (under 18), the variation requires court approval.

It’s also essential to consider the tax implications carefully. While a deed of variation is commonly used to save IHT — for example, by redirecting assets to make use of the nil rate band (£325,000) or the residence nil rate band (£175,000 per person when a qualifying home passes to direct descendants) — it can also have capital gains tax consequences. If the deed includes the appropriate election, HMRC treats the variation as if the deceased made it, which means the beneficiary receiving the redirected assets is treated as acquiring them at probate value (the value at death), not at the date of the deed.

To navigate these complexities, it’s advisable to seek specialist legal advice. As we often say, the law — like medicine — is broad. You wouldn’t want your GP performing surgery, and equally, a deed of variation should be handled by someone who specialises in this area of law.

Process of Implementing a Deed of Variation

Changing how an estate is distributed after death requires a carefully drafted deed of variation. This process allows beneficiaries to redirect their entitlement from the deceased’s estate to achieve better outcomes for the family — whether that’s saving tax, providing for someone who was left out, or protecting a vulnerable beneficiary.

Steps to Create a Deed of Variation

To implement a deed of variation, several steps must be followed:

• Identify the changes needed: Beneficiaries must decide how they wish to redirect their entitlement. This might involve passing assets to another family member, to charity, or into a discretionary trust.
• Take specialist legal advice: A solicitor experienced in estate planning should be consulted to ensure the deed achieves the desired tax treatment and is compliant with the legal requirements.
• Draft the deed: The deed of variation must be in writing and clearly identify the original will provisions (or intestacy entitlements) being varied, and what the new distribution will be. It must include the required statutory statements for IHT and/or CGT reading-back treatment.
• Obtain signatures: Every beneficiary whose entitlement is being reduced must sign the deed. If the variation increases the IHT payable on the estate, the personal representatives (executors or administrators) must also give their written consent.
• Notify HMRC if required: If the deed affects the IHT position of the estate, a copy should be sent to HMRC along with the relevant IHT account or a supplementary account. There is no separate “approval” process — HMRC does not need to approve the deed, but they must be notified where IHT is affected.

Required Documentation

The documentation required for a deed of variation typically includes:

• The deed of variation itself, properly drafted, signed, and dated.
• A copy of the original will (or details of the intestacy entitlements if there was no will).
• The Grant of Probate or Letters of Administration (to confirm the personal representatives).
• Evidence of identity for the beneficiaries signing the deed.

It’s crucial to ensure all documentation is accurately prepared to avoid HMRC rejecting the reading-back treatment or delays in estate administration.

Timeframes for Submission

The overriding time limit is that the deed of variation must be executed within two years of the date of death. This is a hard deadline — miss it, and you lose the ability to have the variation treated as made by the deceased for tax purposes. Where the personal representatives’ consent is required (because the variation increases IHT), they must give this consent within six months of the date of the deed. It’s wise to act promptly — waiting until the final months creates unnecessary risk, particularly if there are multiple beneficiaries whose agreement is needed.

Tax Implications of a Deed of Variation

One of the primary reasons families use a deed of variation is to improve the IHT position of an estate. But the tax implications extend beyond inheritance tax alone — capital gains tax, income tax, and even stamp duty land tax can all be affected. Understanding these consequences is essential before signing anything.

Inheritance Tax Considerations

A deed of variation can be a highly effective tool for reducing inheritance tax. IHT is charged at 40% on the value of a taxable estate above the nil rate band (currently £325,000 per person, frozen until at least April 2031). The residence nil rate band adds a further £175,000 per person — but only where a qualifying residential property passes to direct descendants (children, grandchildren, or step-children). For a married couple, the combined maximum IHT-free threshold can be up to £1,000,000.

A deed of variation can help in several ways. If the deceased left everything to their spouse (IHT-free under the spousal exemption), the first death’s nil rate band may go unused. A deed of variation can redirect up to £325,000 of assets — perhaps into a discretionary trust for the benefit of the family — making use of the nil rate band that would otherwise be wasted. Similarly, if the will did not pass the family home to direct descendants, a deed of variation can redirect it to children or grandchildren to secure the residence nil rate band.

Another common use is redirecting at least 10% of the net estate to charity, which reduces the IHT rate from 40% to 36% — a significant saving on larger estates.

Capital Gains Tax and Deeds of Variation

A deed of variation can also affect capital gains tax. If the deed includes the appropriate statutory statement (electing for CGT reading-back), the person receiving the redirected assets is treated as acquiring them at probate value — the market value at the date of death. This is the same base cost they would have received if the deceased’s will had originally specified the new distribution.

This reading-back treatment can be advantageous. For example, if an asset has risen in value between the date of death and the date of the deed, the beneficiary receiving it under the variation gets the higher probate-value base cost, potentially reducing any future CGT liability when they sell. Conversely, if the variation redirects assets into a discretionary trust, holdover relief may be available, deferring any CGT until the trustees eventually dispose of the asset.

It’s worth noting that the IHT reading-back election and the CGT reading-back election are separate — you can elect for one, both, or neither, depending on what achieves the best overall tax outcome.

Other Potential Tax Consequences

Beyond IHT and CGT, a deed of variation can have other tax consequences that are sometimes overlooked. If the variation redirects income-producing assets (such as rental property or investment portfolios) to a different beneficiary, this changes who is liable for income tax on that income going forward.

If the deed redirects assets into a discretionary trust, the trust will be subject to the trust tax regime: income tax at 45% on non-dividend income (39.35% on dividends) above the first £1,000, and CGT at the trust rate (currently 24% on residential property, 20% on other assets) with a reduced annual exempt amount.

It’s also important to be aware that if a deed of variation involves the transfer of property, stamp duty land tax (SDLT) can sometimes arise — although in many cases, variations that are genuinely made for no monetary consideration and within the two-year window are not subject to SDLT. However, the rules are technical, and professional advice is essential. If a beneficiary redirects assets and receives something in return (known as consideration), the variation loses its tax-favoured status entirely.

Who Can Initiate a Deed of Variation?

Understanding who has the right to initiate a deed of variation is fundamental. It’s not the executors who decide — it’s the beneficiaries. The executors’ role is administrative, while the beneficiaries hold the power to redirect their own inheritance.

Beneficiaries’ Rights

Beneficiaries have the right to vary their own inheritance — and only their own. A beneficiary can redirect their share of the estate, but they cannot alter another beneficiary’s entitlement without that person’s consent. This is because a deed of variation works by the beneficiary effectively giving up what they are entitled to and directing it elsewhere.

For example, if a will leaves an estate equally among three siblings, one sibling can use a deed of variation to redirect their one-third share to their own children. The other two siblings’ shares remain completely unaffected, and their consent is not needed — because their entitlements haven’t changed. However, if the proposed variation would reduce any beneficiary’s share, that beneficiary must give their written consent.

An important limitation: if a beneficiary who would be worse off under the variation is a minor (under 18), the court must approve the variation on the minor’s behalf. This adds time and cost, so it’s a factor to consider early in the process.

Role of Executors in the Process

Executors (or administrators) have a specific but limited role in the deed of variation process. Their primary duty is to administer the estate according to the will. They do not initiate a deed of variation — that is the beneficiaries’ prerogative. However, executors must give their written consent if the variation results in more IHT becoming payable on the estate, because they are personally liable for ensuring the correct amount of IHT is paid.

Here is a summary of the key roles and responsibilities:

In summary, beneficiaries hold the decision-making power when it comes to a deed of variation, while executors have a supporting and compliance role. Understanding these distinct responsibilities is essential for anyone considering changing how an estate is distributed after death.

Situations Where a Deed of Variation is Beneficial

When the original will no longer serves the family well, a deed of variation provides a valuable opportunity to put things right. There are several common scenarios where this tool proves particularly useful.

Resolving Disputes Among Beneficiaries

Disputes among beneficiaries are unfortunately common — whether due to perceived unfairness in the will, changed family dynamics, or practical difficulties with the assets left to particular individuals. A deed of variation can help resolve these disputes by allowing beneficiaries to agree a redistribution that everyone finds acceptable, without the expense and stress of a court claim.

For instance, if one sibling has been left the family home but another sibling feels overlooked, the beneficiary who inherited the property might agree to vary their inheritance so that a portion of the estate’s value passes to the other sibling. This kind of voluntary arrangement can preserve family relationships and avoid the costs of contested probate litigation, which can easily run into tens of thousands of pounds.

Changing Distribution of Assets

Circumstances often change between the time a will is written and when the person dies — sometimes by years or even decades. A deed of variation allows beneficiaries to update the distribution to reflect current reality.

For example, if a beneficiary has become financially secure since the will was written, they might choose to redirect their inheritance to grandchildren — potentially using the deceased’s residence nil rate band (£175,000 per person) by ensuring the family home passes to direct descendants. Alternatively, a beneficiary might redirect assets to a spouse or civil partner to take advantage of the spousal exemption and defer IHT. These are straightforward tax-planning opportunities that a deed of variation makes possible even after death.

Protecting Vulnerable Beneficiaries

In some cases, beneficiaries may be vulnerable — due to age, disability, mental health difficulties, addiction, or simply not being ready to manage a large sum of money. A deed of variation can redirect their inheritance into a discretionary trust, where trustees manage the assets on their behalf and have absolute discretion over when and how distributions are made.

This is particularly important because a discretionary trust ensures that no beneficiary has a legal right to the trust assets. This means the assets are protected from the beneficiary’s creditors, are not counted as their capital for means-tested benefits (including local authority care funding), and cannot be claimed by a spouse in divorce proceedings. A beneficiary with a disability may also qualify for a disabled person’s trust, which receives more favourable IHT and income tax treatment.

It’s worth emphasising that a deed of variation is a reactive tool — it fixes problems after death. The most effective approach is always proactive estate planning during your lifetime. Setting up a lifetime trust, writing a comprehensive will, and creating Lasting Powers of Attorney means your family won’t need to rely on a deed of variation at all. As we often say: plan, don’t panic. To understand more about how wills interact with post-death planning, you can read our detailed article on myth vs fact: Can a will really be changed after the person dies.

Alternatives to a Deed of Variation

While a deed of variation is a valuable post-death planning tool, it’s not the only option available. In some situations, other legal routes may be more appropriate — particularly where beneficiaries cannot agree, where the will itself is defective, or where someone has been unfairly excluded.

Revocation of Wills

It’s important to clarify a common misconception: a will cannot be revoked after the testator has died. Revocation is something only the person who made the will can do during their lifetime. A will is automatically revoked if the testator makes a new will that expressly revokes all previous wills, or if they deliberately destroy the original will with the intention of revoking it. Marriage also automatically revokes a will in most cases (unless the will was made in contemplation of that marriage).

After death, the following options exist for those unhappy with a will’s provisions:

• A deed of variation — where beneficiaries voluntarily redirect their own entitlements (as discussed throughout this article).
• A claim under the Inheritance (Provision for Family and Dependants) Act 1975 — where eligible applicants believe the will (or intestacy) does not make reasonable financial provision for them.
• A claim to challenge the validity of the will itself — on grounds such as lack of testamentary capacity, undue influence, fraud, or failure to comply with the formalities required by the Wills Act 1837.

These are very different routes with different legal tests, costs, and outcomes — so specialist advice is essential before pursuing any of them.

Court Applications for Variation

A court application under the Inheritance (Provision for Family and Dependants) Act 1975 is the main formal route for someone who believes they have been inadequately provided for by the will or the intestacy rules. Eligible applicants include spouses and civil partners, former spouses who have not remarried, children of the deceased, dependants, and anyone who was being maintained by the deceased immediately before death.

The court considers a range of factors — including the applicant’s financial needs and resources, the size of the estate, any obligations the deceased had towards the applicant, and any disability of the applicant — before deciding whether to make an order. The standard of provision is “reasonable financial provision,” which for spouses is assessed on a broader basis than for other applicants.

Court applications can be lengthy, stressful, and expensive — contested probate litigation typically costs tens of thousands of pounds and can take a year or more to resolve. They also become a matter of public record. For these reasons, a negotiated deed of variation is almost always preferable where the beneficiaries can reach agreement between themselves.

It’s worth remembering that court claims under the 1975 Act must generally be brought within six months of the date of the Grant of Probate or Letters of Administration — a much shorter window than the two years available for a deed of variation.

If you’re facing difficulties with the administration of an estate, or you believe a will doesn’t adequately provide for you or a family member, seeking specialist legal advice early is critical. The right approach depends entirely on the specific circumstances — and acting promptly preserves the widest range of options.

Common Misconceptions About Deeds of Variation

Deeds of variation are frequently misunderstood, which can lead to missed opportunities or costly mistakes. Let’s address the most common misconceptions so you can approach this area of estate planning with confidence.

Can Wills Be Changed Without a Deed?

One widespread misconception is that the terms of a will can somehow be informally changed after death — perhaps by the family simply agreeing among themselves who gets what. In reality, while families can of course agree informally how to share out personal possessions, any variation that you want HMRC to recognise for tax purposes must be made by a formal deed of variation. An informal family agreement has no legal force for IHT or CGT purposes and could create unexpected tax liabilities.

It’s also worth understanding what a deed of variation actually does: it doesn’t rewrite the will. The will remains exactly as the deceased left it. What the deed does is redirect a beneficiary’s entitlement — and, if the correct statutory statements are included, HMRC treats the new arrangement as if the deceased had written their will that way in the first place. This “reading back” is what gives the deed its tax-planning power.

The Belief That All Beneficiaries Must Agree

Another common misconception is that every single beneficiary named in the will must agree to a deed of variation. This is not correct. Only those beneficiaries whose entitlement is being reduced or adversely affected need to give their consent. A beneficiary who is receiving more under the variation, or whose entitlement is unchanged, does not need to consent (although it’s good practice to keep all beneficiaries informed).

For example, if a parent leaves their entire estate to their three children equally, and one child decides to redirect their share to their own children (the deceased’s grandchildren), only that one child needs to sign the deed. The other two siblings’ shares are unaffected, so their consent is not required. However, if the proposed variation involves taking something away from one beneficiary to give to another, the beneficiary losing out must consent — and if that beneficiary is under 18, court approval is needed.

Understanding these realities is important. A deed of variation is a powerful but technical tool — and getting it wrong can mean the tax benefits are lost entirely. Whether you’re a beneficiary considering redirecting your inheritance or an executor trying to understand your obligations, specialist advice is the safest route. Trusts are not just for the rich — they’re for the smart, and the same principle applies to post-death estate planning tools like deeds of variation.

Conclusion: Making Informed Decisions

A deed of variation is one of the most useful — and underused — tools in UK estate planning. It offers a genuine second chance to get the distribution of an estate right, whether that means saving inheritance tax, providing for a family member who was left out, or protecting vulnerable beneficiaries through a trust. But it must be done properly, within the strict two-year time limit, and with a clear understanding of the tax consequences.

Expert Guidance for Estate Planning

Seeking specialist legal advice is essential — both for implementing a deed of variation and for broader estate planning. The most effective approach is always to plan ahead during your lifetime, so that your family doesn’t need to rely on post-death fixes. A properly drafted will, combined with lifetime trusts where appropriate and Lasting Powers of Attorney, provides comprehensive protection. At MP Estate Planning, we provide clear, accessible guidance on navigating these decisions.

Balancing the Pros and Cons

A deed of variation can achieve significant tax savings and resolve family difficulties — but it requires the willing cooperation of the beneficiaries involved, it must be completed within two years, and the tax implications need careful analysis. It’s not a tool to use lightly or without professional input. When you compare the cost of getting proper advice to the potential IHT savings (40% of any amount above the nil rate band), the investment is almost always worthwhile.

Clear Communication Among Beneficiaries

Effective communication among beneficiaries is the single most important factor in a successful deed of variation. Misunderstandings, suspicion, and family tensions can derail even the most tax-efficient plan. We recommend having open, honest conversations early in the process — ideally with professional guidance to ensure everyone understands the implications. Not losing the family money provides the greatest peace of mind above all else.

In conclusion, making informed decisions about deeds of variation requires a clear understanding of the law, the tax consequences, and the family dynamics involved. Plan, don’t panic — and always seek specialist advice before committing to any changes.
