Change a Will After Death: UK Rules for Beneficiaries and Executors

It is possible to change a will after death in certain circumstances, but the deceased person’s will itself is not simply rewritten. Beneficiaries may be able to redirect all or part of their inheritance through a deed of variation, while separate legal procedures may apply where a will contains an error or is being challenged.

Understanding the distinction is important. A deed of variation is generally used when beneficiaries agree to alter how an inheritance passes, whereas rectification or court proceedings deal with different legal issues. There can also be important Inheritance Tax (IHT) and Capital Gains Tax (CGT) consequences when changing an estate after death. Wider personal tax planning in uk can also help beneficiaries consider how redirected assets may affect their overall tax and financial position.

Can You Change a Will After Death?

Once someone has died, nobody can alter their will on the deceased person’s behalf. Executors must generally administer the estate according to the valid will and cannot decide themselves to distribute assets differently.

However, beneficiaries can sometimes change what happens to the inheritance they are entitled to receive. The most common way of changing a will after death for estate planning purposes is through a deed of variation.

Other circumstances may require different procedures, particularly where there is a mistake in the will, concerns about its validity or a claim against the estate.

What Is a Deed of Variation?

A deed of variation allows a beneficiary to redirect some or all of the inheritance they receive from a deceased person’s estate.

For example, someone who inherits assets from a parent might decide that they would prefer those assets to pass directly to their own children. A variation can potentially achieve this without requiring the original beneficiary to receive the inheritance first and then make a separate gift.

A variation can be made whether the deceased left a will or died intestate. Despite the commonly used expression “changing the will”, the original will itself remains unchanged. Instead, the variation changes how particular estate assets are distributed.

Who Must Agree to a Deed of Variation?

There does not necessarily need to be agreement from every beneficiary of the estate. However, anyone whose inheritance is reduced or otherwise adversely affected by the proposed change must agree to it.

The executors may also need to be involved where the variation affects the administration of the estate or creates additional tax payable by the estate.

A beneficiary cannot normally use a deed of variation to reduce another beneficiary’s entitlement without that person’s consent.

What Is the Two-Year Rule for Changing an Estate After Death?

Timing is particularly important where the variation is intended to receive the relevant IHT or CGT treatment.

To qualify for the statutory tax treatment, the variation generally needs to be completed within two years of the deceased person’s death.

The variation should clearly identify the original disposition being changed and the new distribution. Where the parties want the variation to be treated for IHT or CGT purposes as if the deceased had made the revised disposition, the document must contain the appropriate statement for the relevant tax provisions to apply.

Beneficiaries considering a variation should therefore review their position before distributing or disposing of inherited assets rather than waiting until the two-year deadline approaches.

Inheritance Tax and a Deed of Variation

A deed of variation can have important consequences for Inheritance Tax.

Where the relevant requirements are satisfied, the variation can be treated for IHT purposes as though the revised gift had been made by the deceased rather than by the beneficiary redirecting their inheritance.

This can be relevant where, for example, an inheritance is redirected to a spouse, civil partner or qualifying charity and an IHT exemption may apply.

A variation can also form part of wider family estate planning. However, it should not be assumed that redirecting an inheritance will automatically reduce IHT. The effect depends on the original estate, the beneficiary receiving the redirected assets and the exemptions or reliefs available. Where pension wealth is also involved, the IHT treatment of pension death benefits in London should be considered separately from assets passing under the will.

Capital Gains Tax When Amending an Inheritance

Amending a will after death can also have CGT implications, particularly where the estate contains property, shares or other assets that may increase in value.

Where the statutory requirements are met, a qualifying variation can generally be treated as made by the deceased for CGT purposes rather than as a disposal by the original beneficiary.

This treatment can be important where assets have increased in value between the date of death and the date on which the family decides to alter the distribution.

Tax consequences should therefore be considered before signing the variation, particularly for estates containing substantial investments, businesses or property. Where the estate includes company shares acquired through equity compensation, estate planning with RSUs in London can help clarify the tax and succession issues associated with those assets.

Can a Mistake in a Will Be Corrected?

A deed of variation should not be confused with rectification of a will.

If a will fails to reflect the deceased person’s intentions because of certain drafting or clerical errors, it may be possible to apply to the court for rectification. This is a legal process and is different from beneficiaries voluntarily agreeing to redirect their inheritance.

Where an error is suspected, legal advice should be obtained promptly because specific requirements and time limits can apply.

What If Someone Wants to Challenge the Will?

A beneficiary or family member who believes a will is invalid cannot simply alter it using a deed of variation.

A will may potentially be challenged on legal grounds such as lack of testamentary capacity, undue influence, fraud or failure to satisfy the formal requirements for a valid will. 

Certain family members and dependants may also be able to bring a claim under the Inheritance (Provision for Family and Dependants) Act 1975 where they believe reasonable financial provision has not been made for them.

These are legal disputes rather than tax-planning variations and specialist probate advice should be obtained.

What Are the Executor’s Responsibilities?

Executors remain responsible for administering the estate correctly. Understanding the tax responsibilities when managing an estate can help executors deal with estate valuations, HMRC reporting and taxes arising during the administration period. Their duties can include: 

• Locating the valid will and identifying beneficiaries.
• Valuing the deceased person’s assets and liabilities.
• Dealing with probate and relevant tax reporting.
• Paying estate debts and taxes.
• Maintaining accurate estate administration records.
• Distributing the remaining estate according to the will, intestacy rules and any valid subsequent variation.

Executors should not redistribute assets merely because family members informally agree to a different arrangement. Where the distribution is being formally varied, appropriate documentation should be completed and retained with the estate records.

When Might Changing an Estate After Death Be Considered?

A Change an Estate After Death may be considered where the original beneficiary no longer needs the inheritance, wants assets to pass to another generation, wishes to make provision for another family member or wants part of the inheritance to pass to charity.

It may also be relevant where circumstances have changed significantly since the deceased prepared their will. For deaths on or after 6 April 2027, the treatment of unused pension funds and IHT from April 2027 may also need to be considered when reviewing the family’s wider estate position. 

However, tax should not be the only consideration. Beneficiaries should consider their own financial requirements, the needs of other family members and the legal consequences of giving up an inheritance permanently.

What Should You Check Before Changing a Will After Death?

Before proceeding with a deed of variation or another change to an estate distribution, establish exactly what the beneficiary is entitled to receive and whether the assets have already been distributed.

You should also consider:

• Whether the proposed variation is within two years of death.
• Which beneficiaries will be affected.
• Whether all affected parties have agreed.
• The potential IHT consequences.
• The potential CGT consequences.
• Whether the estate contains property, businesses or other complex assets.
• Whether legal advice is required to prepare the variation.

Where tax treatment is important, the wording of the document should be reviewed carefully before the variation is completed.

Understanding the Rules for Changing a Will After Death

The ability to change a will after death does not give executors or relatives the power to rewrite the deceased person’s final wishes. Instead, beneficiaries can in appropriate circumstances use a deed of variation to redirect their own inheritance, while court procedures may be required for errors, disputes or claims against the estate.

Because a variation can affect Inheritance Tax, Capital Gains Tax and the rights of beneficiaries, the legal and tax consequences should be established before assets are redistributed. The two-year tax deadline also means beneficiaries should consider their options early in the estate administration process. Beneficiaries receiving pension benefits should separately consider the tax on inherited private pensions in London, as pension benefits may follow different tax and succession rules from assets distributed under the will.

Case Study: Redirecting an Inheritance Through a Deed of Variation

Michael approached our Fulham office after inheriting a substantial investment portfolio and a share of his late mother’s estate. He was financially secure and wanted part of his inheritance to pass directly to his two adult children rather than receiving the assets himself and making gifts later.

Cigma Accounting reviewed the proposed redistribution alongside the estate’s existing Inheritance Tax position. As less than two years had passed since his mother’s death, we explained that a properly structured deed of variation could potentially allow Michael to redirect part of his entitlement while obtaining the relevant IHT and Capital Gains Tax treatment, provided all statutory conditions were satisfied.

The estate contained shares that had increased in value since the date of death, so the Capital Gains Tax implications also required consideration before any assets were transferred or sold. We helped Michael understand why completing the variation before dealing with the investments could be important and why the appropriate tax statements needed to be included in the documentation.

Our wider review covered Inheritance Tax, Capital Gains Tax, estate administration and Michael’s personal tax position. We worked alongside his solicitor, who handled the legal drafting of the deed, while we assessed the tax consequences of the proposed redistribution.

Michael could then decide how much of his inheritance he genuinely wished to redirect, knowing how the variation could affect both the estate and his own tax position. The executors also had clear documentation showing how the revised distribution should be implemented.
