Deathbed marriages: how a late marriage revokes a will and rewrites who inherits

What a marriage weeks before death does to an estate

In England and Wales, getting married or entering a civil partnership automatically revokes any will made before the ceremony, unless that will was expressly made in contemplation of the marriage. GOV.UK's guidance on updating a will is blunt about it: getting married "cancels any will you made before". If the person then dies without signing a new will, the intestacy rules decide who inherits, and those rules put the new husband, wife or civil partner at the front of the queue.

That combination is why a marriage entered into shortly before death, sometimes called a deathbed marriage, can quietly redirect an estate away from the children or other beneficiaries named in a will the deceased believed was still in force. This page explains the mechanics in general terms. It is general information, not legal or financial advice, and anyone facing a real dispute of this kind should speak to a contentious probate solicitor.

The two rules that do the work

Rule one: revocation by marriage. Under the Wills Act 1837, marriage or civil partnership revokes an earlier will automatically. No announcement is made and no document changes hands; the will simply stops being valid the moment the ceremony completes. The main exception is a will made "in contemplation of" a specific forthcoming marriage, where the document itself makes clear the testator expected to marry that particular person and intended the will to survive the wedding.

Rule two: intestacy favours the spouse. With the old will revoked and no new one made, the estate passes under the intestacy rules. Where the deceased leaves a spouse or civil partner and children, the spouse receives the personal possessions, a statutory legacy of £322,000 (for deaths on or after 26 July 2023, set by the Fixed Net Sum Order 2023), and half of everything above that figure. The children share the other half. Where there are no children, the spouse takes the whole estate. Our full guide to the intestacy rules for spouses and children works through the split in detail, and who inherits if there is no will covers the wider order of entitlement.

Put the two rules together with a modest estate and the effect is stark. Suppose Raymond, 82, made a will years ago leaving his £500,000 estate equally to his son and daughter. He marries his companion three weeks before he dies and never signs a new will. The old will is revoked. On intestacy his new wife receives the possessions, £322,000, and half of the remaining £178,000, around £411,000 in total. The two children share roughly £89,000 between them instead of £250,000 each.

Why this is called the predatory marriage problem

Nothing in the example above requires bad faith; plenty of late-life marriages are entirely genuine, and the law is simply doing what it has done since the Victorian era. The concern arises where someone marries a person who is elderly, seriously ill or losing capacity precisely in order to inherit from them. Two features of the current law make that possible:

• The capacity threshold for marriage is lower than the threshold for making a will. A person may no longer have the testamentary capacity to sign a new will, yet still be found to have had capacity to marry. The marriage then revokes the will they made when they were well, and they cannot make a new one.
• Few people know the revocation rule exists. A testator, and their family, can believe an old will still governs the estate when in law it was cancelled on the wedding day.

The Law Commission's report on modernising wills law, published on 16 May 2025, recommends abolishing revocation by marriage altogether, saying it is concerned the rule is "motivating predatory marriages" as a form of financial abuse. That recommendation needs legislation before anything changes, so for now the revocation rule remains the law in England and Wales.

What families can and cannot do

This is contested and fact-specific territory, so we describe the routes only in outline. Before a wedding, relatives who believe a vulnerable person lacks capacity to marry can raise concerns with the register office. After a death, challenging the marriage itself is legally difficult: a marriage entered into without capacity is generally voidable rather than void, and the estate has usually already vested under intestacy by the time concerns surface. Depending on the facts, family members may be able to bring a claim for reasonable financial provision, or investigate the validity of documents made around the same time; the questions overlap with those covered in our guides to mental capacity and will validity and contesting a will. None of this is a route anyone should attempt without specialist advice, and a contentious probate solicitor is the right starting point.

The practical lesson for everyone else

For anyone planning their own affairs, the takeaway is simpler: a will is not a set-and-forget document. Marriage, civil partnership and remarriage all revoke it unless it was made in contemplation of that ceremony, so any change in relationship status should trigger a fresh will, and a will made shortly before an expected marriage should say so expressly. Our making a will checklist walks through the points a new or updated will needs to cover, the wills pillar guide explains the process end to end, and surviving spouses navigating an estate can start with our hub for surviving spouses. If a late marriage has already scrambled who inherits in your family, a specialist in contentious probate can assess the position while the key evidence and time limits are still workable.
