Mutual Wills vs Mirror Wills: What’s the Difference?

When couples make Wills together, the terms “mirror Wills” and “mutual Wills” are often used interchangeably. In reality, they are very different legal arrangements, and misunderstanding the distinction can have significant consequences for a family’s estate planning.

In practice, most couples who ask for “mutual Wills” actually mean mirror Wills. True mutual Wills are relatively rare because they create a binding agreement that can restrict the surviving partner’s freedom for the rest of their life.

What Are Mirror Wills?

Mirror Wills are two separate Wills containing identical or near-identical provisions. Typically, each partner:

• Leaves their estate to the other on the first death; and
• Leaves the estate to the same beneficiaries (usually children) after the second death.

Although the Wills mirror one another, they remain entirely separate documents. Either party can change or revoke their own Will whenever they choose, provided they have the necessary mental capacity.

This flexibility is one of the major reasons mirror Wills are so popular and recommended.

The key drawback is that nothing prevents the survivor from changing their Will after the first death.

What Are Mutual Wills?

Mutual Wills go much further than mirror Wills. A mutual Will arrangement involves a legally binding agreement between two people that neither will change their testamentary wishes without the other doing so, this becomes impossible once the first party to a mutual Will passes away.

The Wills themselves may look similar to mirror Wills, but there is an additional contractual element. Upon the death of the first person, the survivor becomes bound by the agreement and cannot later alter the ultimate destination of the assets.

If the survivor tries to depart from the agreement, the courts may intervene to enforce the original arrangement.

Mutual Wills are typically used where certainty is more important than flexibility. A common example is a blended family.

A mutual Will arrangement can provide protection against this risk by ensuring that the agreed beneficiaries ultimately inherit.

The Importance of Clear Evidence

One of the difficulties with mutual Wills is that the courts require clear evidence that a binding agreement was intended.

The fact that two Wills are identical does not automatically make them mutual.

In England and Wales, the courts generally require convincing evidence that the parties intended to create a legally binding arrangement and not merely matching Wills. For that reason, solicitors drafting genuine mutual Wills usually record the agreement in very clear terms.

The decision between making mutual Wills and mirror Wills is an important one and not one to be made quickly.
