Making Changes to a Will / Intestacy After Death

Read time: 6 mins

This blog explains how, in certain circumstances, the distribution of an estate can be altered after death through post‑death variations. It outlines why beneficiaries may choose to vary a Will or intestacy, such as improving tax efficiency, achieving a fairer outcome, or aligning with the deceased’s intended wishes, and emphasises the importance of completing such changes within two years to secure inheritance tax and capital gains tax benefits. The article highlights the two primary methods available, Deeds of Variation and Disclaimers, clarifying their differences, requirements, and limitations, including the need for consent and the inability to receive compensation for relinquished entitlements.

In some instances it may be beneficial or desirable for entitlements under a Will, or in respect of an intestacy, to be varied after a person has passed away.

These are what are known as post-death variations.

There are many reasons why you might choose to vary how an estate should pass, for example, to mitigate the tax consequences of inheriting, to make a distribution more equitable, or to give effect to the deceased’s wishes.

To be fully effective for tax purposes, the instrument to vary the Will/intestacy must be entered into within two years of the date of passing of the deceased. If this is done, and the relevant elections are made, the new provisions will essentially be ‘written back’ for both inheritance tax and capital gains tax purposes. This essentially means that the gifts will take effect as if they were in the original Will.

If there are any adverse tax consequences of the variation, then the personal representatives of the deceased should also be a party to the document, as they will be responsible for ensuring that any applicable tax is paid.

There are two main methods of varying an estate: Deeds of Variation and Disclaimers.

Deeds of Variation

A Deed of Variation is used to essentially rewrite the distribution of an estate and direct where an entitlement should be diverted.

It can be used to name a new beneficiary entirely or to vary the proportions in which existing beneficiaries should inherit.

The benefit of utilising a Deed of Variation is that you have control over where the assets in question will then pass.

In order to enter into a Deed of Variation, everyone who is adversely affected by the Deed must agree. There must also be no compensation paid in respect of anyone relinquishing their entitlement, and the party giving up some or all of their entitlement must also not have enjoyed any benefit from the assets in question before doing so.

Disclaimers

Disclaimers are often used instead where it is not possible or practical to obtain the consent of all parties who may be affected, i.e. if some parties are under the age of 18 or do not have capacity to consent.

Essentially, under a Disclaimer, the beneficiary who is entitled is saying that they do not wish to benefit, and the gift will then pass to the next person who is entitled under the terms of the Will / the rules of intestacy.

Using a Disclaimer, you cannot specify who you would wish to benefit instead.

As with a Deed of Variation, no compensation should be paid in respect of anyone relinquishing their entitlement, and the party giving up some or all of their entitlement must also not have enjoyed any benefit from the assets in question before doing so.

It is strongly recommended that you take legal advice before entering into any such post-death variation, because, as well as the potential taxation consequences (both positive and negative) of doing so, it is imperative that the document is right first time, as it is not possible to vary the same entitlement more than once.

Frequently Asked Questions

What is a post-death variation?

A post-death variation is a legal arrangement that allows beneficiaries to change how a deceased person’s estate is distributed after their death.

Why would someone want to change a Will after death?

Common reasons include reducing inheritance tax, making the distribution fairer between beneficiaries, or better reflecting what the deceased may have intended.

What is a Deed of Variation?

A Deed of Variation is a formal document that enables beneficiaries to redirect all or part of their inheritance to someone else or adjust how assets are divided.

What is a Disclaimer?

A Disclaimer is when a beneficiary chooses to give up their entitlement entirely, allowing the gift to pass to the next eligible person under the Will or intestacy rules.

What is the difference between a Deed of Variation and a Disclaimer?

A Deed of Variation allows you to choose who receives your share, whereas a Disclaimer simply refuses the inheritance without directing where it goes.

Examples

Example A

Tax efficiency for a surviving spouse

After Jim passes away, his estate is left entirely to his partner. She later realises this could increase inheritance tax on her own estate when she dies. To mitigate this, she enters into a Deed of Variation to redirect part of the inheritance to their children, making use of available tax allowances.

Example B

Equalising gifts between children

A Will leaves unequal shares to two siblings, but after the parent’s death, the sibling receiving the larger portion decides this is unfair. They use a Deed of Variation to redistribute part of their inheritance to ensure both receive equal amounts.
