Why Mutual Wills Are Rarely the Best Choice
Introduction
When planning for the future, many couples are advised about “mirror wills” and “mutual wills.” Although these terms are often used interchangeably, there are crucial differences – and, in contentious will disputes, the distinction can have far-reaching consequences. At Clodes Solicitors, our specialist team regularly advises clients on probate disputes, including challenges arising from mutual wills.
If you are reviewing your estate planning or find yourself facing issues surrounding an old mutual will, understanding your position is vital. In this article, we explain what mirror and mutual wills are, why mutual wills often create more problems than they solve, and what options are available if you need to change a will after one party has died. If you need advice, don’t hesitate to contact our contentious wills solicitors today.
What Are Mirror Wills?
Mirror wills are two separate will (usually made by married, civil partnered, or cohabiting couples) which are practically identical. Typically, each party leaves their estate to the other (or, if the other has died, to the same family members or chosen beneficiaries in equal or agreed shares).
Example:
Anne and John are married. Both execute a will leaving everything to the other, or, if the other has predeceased, to their children equally. Each party is free to change their will at any time while alive.
- Advantages of Mirror Wills
- Flexibility: Each person can change their will in future (even after the other dies).
- Simplicity: Easier to prepare and update.
- No binding contract: No risk of creating inflexible or unwanted obligations.
What Are Mutual Wills and Why Are They Problematic?
Mutual wills also involve two people making wills on similar terms, plus a legally binding agreement that neither will revoke or change their will without the other’s consent. The critical feature is that, once the first person has died, the survivor is bound by the agreement and their own mutual will – even if they change their mind or personal circumstances change.
Example:
Anne and John both sign mutual wills leaving everything to each other, and then to their children. They expressly agree the wills are “mutual and irrevocable.” When John dies, Anne remains legally bound, by virtue of a constructive trust, not to change her will to benefit anyone else.
- Why Can Mutual Wills Be Problematic?
- Lack of Flexibility: After the first death, the survivor is locked in. They cannot adjust their will, even in response to changed circumstances, new family members, falling out with beneficiaries, or changes in the law.
- Risk of Dispute: Many couples sign mutual wills without truly understanding the implications, often by using home-made forms or under pressure from relatives. Subsequent disputes are common, especially if there are step-children, second marriages, or if family dynamics shift.
- Evidence Requirements: To be binding, there must be clear proof of the agreement’s terms and the parties’ intentions – mere similarity or the use of the word “mutual” is not enough. This leads to costly estate disputes.
- Unwitting Trap: Survivors sometimes change their will, believing they have the same discretion as under a mirror will. Later, disappointed beneficiaries may bring court proceedings for breach of the mutual will trust.
- Contentious Probate: Mutual wills regularly result in complex, drawn-out litigation over whether the agreement was actually intended to be binding, whether there was lack of understanding, undue influence, or mistakes about the documents signed.
Common Reasons People Use Mutual Wills – and Why Alternatives Are Usually Better
Mutual wills are often used by couples wishing to “protect the bloodline” – for example, in blended families, to ensure children from both sides receive an inheritance. Others are advised they provide “certainty” against the survivor changing the will and excluding the first-to-die’s children.
However, there are modern alternatives which are far safer and more flexible:
- Life interest trusts
- Discretionary trusts in wills
- Gifting restrictions/specifically tailored estate structures
Our experience as contentious will experts shows that almost all legitimate aims of a mutual will can be achieved better (and with less risk) with a bespoke trust or a carefully drafted mirror will.
Can You Change a Mutual Will After One Party Has Died?
No. This is the single biggest pitfall of mutual wills. Once the first testator has died, the survivor is bound in equity to honour the agreement. If they make a new will, their executors may be compelled to distribute the estate according to the mutual will, not the later instructions.
If you believe you have entered into a mutual will in the past and now wish to change it, urgent legal advice is required – especially before one party dies. If only one party is left, setting aside a mutual will is extremely difficult – the courts will only allow this in exceptional circumstances (e.g. proof of undue influence, lack of capacity, or mistake).
