Deed of Variation: Post-Death Estate Planning Explained

One of the most powerful and underused tools in estate planning is the deed of variation (DoV). Unlike lifetime planning, which must be done years in advance, a deed of variation operates retrospectively after death. It allows the beneficiaries named in a will — or the people who would benefit under intestacy — to redirect some or all of their inheritance as if the deceased had made those changes themselves. Used well, it can dramatically reduce the inheritance tax (IHT) bill on an estate and correct mistakes in a will that was not updated before death.

This guide explains the rules in detail. It does not constitute legal or tax advice; every estate is different and professional advice should be obtained before executing a variation.

The Two-Year Window

The fundamental rule is timing. A deed of variation must be executed within two years of the date of death. Miss this deadline and the planning opportunity is gone permanently — there is no extension and no discretion available to HMRC or the courts.

The two-year period runs from the date of death, not from the grant of probate or letters of administration. In practice this means that even where an estate is complex or disputed, the clock is ticking from day one. Where there is any possibility that a variation might be useful, advisers should raise it early.

The Statutory Framework

Two statutory provisions give deeds of variation their tax effect:

Section 142 IHTA 1984 provides that where a beneficiary redirects their inheritance within two years of death, the variation is treated for IHT purposes as if the deceased had made the gift on death. The redirected assets pass as directed in the deed rather than to the original beneficiary. No IHT is charged on the redirection itself.

Section 62 TCGA 1992 provides the capital gains tax (CGT) equivalent. Where the variation meets the statutory requirements, there is no CGT on the act of variation. The recipient of the redirected assets takes them at their value at the date of death (probate value) for CGT purposes, not at their value at the date of the variation.

Both provisions require the same essential conditions to be met.

Statutory Requirements

For a deed of variation to be effective for tax purposes, it must:

1. Be in writing: an oral variation has no tax effect.
2. Be signed by the varying beneficiary: the person who would have received the assets must be a party and must sign. A third party cannot vary on their behalf without appropriate authority (such as a Court of Protection order for a beneficiary lacking mental capacity).
3. Include a statement of intent: the deed must contain a statement that the parties intend the variation to have effect for IHT purposes under s142 IHTA 1984, and/or CGT purposes under s62 TCGA 1992. HMRC requires these statements to be explicit. If a statement is omitted, the variation will not have the relevant tax effect, even if it is otherwise valid.
4. Not be made for consideration: the person varying must not receive any payment or other benefit in return for making the variation. A variation for value is treated as a disposal by the original beneficiary, triggering CGT on any gain and potentially IHT on the redirected sum.

HMRC no longer requires a copy of the variation to be submitted to it, but the personal representatives should retain the original and it should be sent to HMRC if there is a subsequent enquiry into the estate.

Formatting the Deed

A deed of variation is usually prepared by a solicitor. Key elements include:

• Full details of the deceased (name, date of death, probate reference)
• Identification of the original gift (referring to the relevant clause in the will, or to the intestacy rules)
• The name of the varying beneficiary
• The name of the new recipient (or the trust to which assets are redirected)
• The statutory election statements for IHT and/or CGT
• Signatures and dates — the deed must be executed as a deed (signed, witnessed, and delivered) if it is to be legally effective

If the personal representatives are required to pay additional IHT as a result of the variation, they must also be parties to the deed. This arises where, for example, assets are redirected away from an exempt beneficiary (such as a surviving spouse) and towards non-exempt beneficiaries, increasing the IHT liability.

Disclaimer Versus Variation: What is the Difference?

These are two distinct concepts that are sometimes confused:

A disclaimer is a refusal to accept a gift. The disclaimed share falls back into the estate and passes according to the will or intestacy as if the disclaiming beneficiary had died before the deceased. The disclaiming beneficiary has no control over where the assets go. A disclaimer cannot be partial — you cannot disclaim part of a gift. A disclaimer of a gift under a will or intestacy is brought within the same "read-back" provisions as a variation (s142 IHTA 1984 for IHT and s62(6) TCGA 1992 for CGT), so that it too is treated as if the deceased had made the disposition.

A variation allows the original beneficiary to redirect their inheritance to a specific named person or trust of their choice. This is almost always more flexible than a disclaimer. A variation can be partial — covering only part of the original gift.

In practice, disclaimers are used relatively rarely. They are most useful where a beneficiary genuinely wants nothing to do with an inheritance and does not mind where it goes. More commonly, a variation is appropriate because the varying beneficiary wants to direct assets to specific people or structures.

Post-Death IHT Planning

The most common use of a deed of variation is to save IHT. Consider the following scenarios:

Redirecting to the Surviving Spouse

If a deceased's estate passes entirely to non-exempt beneficiaries (for example, adult children), the full estate may be subject to IHT. A variation redirecting assets to the surviving spouse makes the transfer exempt. The spouse's nil-rate band (and residence nil-rate band) are then preserved for use on the second death.

Using the Nil-Rate Band

Conversely, where assets pass to the surviving spouse under a will drawn before the transferable nil-rate band existed (pre-2007), the nil-rate band on the first death is unused. A variation can redirect assets up to the nil-rate band (currently £325,000) to the children directly or to a discretionary trust, using the band on the first death.

Redirecting to Charity

A gift to a qualifying charity under a deed of variation is treated as if made by the deceased. It reduces the value of the chargeable estate for IHT purposes. If the charitable gift brings the taxable estate down to a level where charitable giving amounts to 10% or more of the "baseline" amount, the IHT rate on the remainder is reduced from 40% to 36%.

Redirecting to a Discretionary Trust

Instead of passing assets directly to a new beneficiary, the variation can redirect assets into a discretionary trust. The settlor of such a trust is the deceased (for IHT purposes), not the varying beneficiary. This is important because:

• The varying beneficiary does not make a potentially exempt transfer (PET) or a chargeable lifetime transfer
• The trust's nil-rate band availability is assessed at the date of death, not the date of the variation
• The trust may provide asset protection and flexibility for future generations

Interaction with the Spouse Exemption

Care is needed where a deed of variation redirects assets away from a surviving spouse. If the estate was assessed on the basis of the spouse exemption and the variation removes assets from that exemption, additional IHT will be payable. The personal representatives must consent and must arrange payment.

CGT Implications

The s62 TCGA 1992 election means there is no CGT charge on the variation itself. The new recipient takes the assets at probate value as their base cost. This is usually the most tax-efficient outcome because assets are uplifted to market value at death for CGT purposes — a gain built up during the deceased's lifetime is extinguished.

If the s62 election is not made (for example, because the varying beneficiary wishes to retain the deceased's original cost base for some planning reason), the variation is treated as a disposal by the varying beneficiary at market value, and CGT may be payable.

Practical Limitations

Deeds of variation cannot be used to:

• Vary a gift of property that has already been sold by the personal representatives (the property no longer forms part of the estate)
• Vary a gift that has already been varied once (a gift can only be varied once)
• Rescue a failed PET — the IHT on a failed PET is fixed at the date of the gift, not the date of death

How Global Investments Can Help

Global Investments advises private clients and their families on post-death estate planning, including whether a deed of variation is appropriate in their circumstances and how to structure any variation to achieve the intended tax outcome.

Our work in this area typically involves reviewing the deceased's will, estimating the IHT position, modelling different variation scenarios, and coordinating with solicitors on the drafting. Where the estate includes overseas assets, we liaise with local advisers to understand how the variation will be treated in the relevant jurisdiction.

We also advise on the broader estate planning implications — whether a variation should redirect to a trust, who should be the trustees, and how the trust fits into the family's long-term wealth plan.
