Yes, mirror wills can be changed without the other person’s consent because they are separate legal documents. Each individual can update or replace their will at any time, even if it was originally created to match their partner’s will.
This is one of the most important — and often misunderstood — aspects of mirror wills in the UK.

Are Mirror Wills Legally Binding Between Partners?
No, mirror wills are not legally binding between partners.
Although they are usually identical, each will is a separate legal document. This means both individuals retain full control over their own will at all times.
In practice, this allows either partner to make changes independently, without needing permission or agreement from the other.
Can One Partner Change Their Mirror Will Without Telling the Other?
Yes, one partner can change their mirror will without informing the other.
There is no legal requirement to notify the other person if changes are made.
This means that even if a couple originally agreed on identical wishes, one partner can later:
- Update their beneficiaries
- Change how assets are distributed
- Create a completely new will
This flexibility is one of the key features of mirror wills — but it can also create uncertainty.
What Happens After One Partner Dies?
After the first partner dies, the surviving partner usually inherits the estate and has full control over their own will.
At this point, they can keep the original terms or make changes.
What Are the Risks of Changing a Mirror Will?
While flexibility can be beneficial, it also introduces potential risks.
These include:
- Children or intended beneficiaries losing their inheritance
- Assets being redirected to new partners or different beneficiaries
- Increased potential for family disputes
