Mirror wills work by allowing two people, usually a couple, to create separate but identical wills that leave their estate to each other and then to the same beneficiaries, such as their children, after both partners have died.
They are one of the most common types of wills in the UK because they are simple, flexible, and effective for couples with shared wishes.

Step-by-Step: How Mirror Wills Work
Understanding how mirror wills work is easier when broken down into simple steps.
Step 1 – Each Partner Creates Their Own Will
Even though they are called “mirror wills”, each person creates their own separate legal document.
Step 2 – Both Wills Reflect the Same Wishes
The wills are usually identical, meaning both partners leave their estate to each other and then to the same beneficiaries.
Step 3 – The First Partner Passes Away
When the first person dies, their estate is typically passed to the surviving partner.
Step 4 – The Surviving Partner Inherits the Estate
The surviving partner takes ownership of the estate and can continue living in the family home or using shared assets.
Step 5 – The Estate Passes to Beneficiaries
After the second partner dies, the estate is passed to the chosen beneficiaries, such as children.
Example of How Mirror Wills Work
For example, a married couple may create mirror wills stating:
- Everything passes to the surviving partner
- After both partners die, the estate goes to their children
This simple structure is why mirror wills are so widely used in the UK.

What Happens After the First Death?
When the first partner dies, the surviving partner usually inherits the entire estate.
For official guidance, the UK Government explains how to make a valid will, ensuring your wishes are carried out correctly.
However, one key point is that mirror wills are not legally binding on each other.
This means the surviving partner can change their will if circumstances change.
Can Mirror Wills Be Changed?
Yes — one of the main features of mirror wills is flexibility.
The surviving partner can update their will at any time, even after the first death.
This is useful if circumstances change, such as remarriage or changes in financial situation.
Mirror Wills vs Joint Wills
The main difference between mirror wills and joint wills is that mirror wills are separate documents, while joint wills are a single document that is often legally binding.
Here is a simple comparison:
| Feature | Mirror Wills | Joint Wills |
|---|---|---|
| Documents | Two separate wills | One single will |
| Flexibility | High | Low |
| Changes allowed | Yes | Usually no |
