Yes, mirror wills can be contested in the UK if there are valid legal grounds, such as lack of mental capacity, undue influence, fraud, or improper execution. Like any will, mirror wills must meet strict legal requirements to be valid.
This means that even if two wills are identical, they can still be challenged under certain circumstances.

What Does It Mean to Contest a Will?
Contesting a will means legally challenging its validity or the way the estate is distributed.
In the UK, this usually involves making a claim through the courts if there are concerns about how the will was created or whether it reflects the true wishes of the person who made it.
Grounds for Contesting a Mirror Will
Mirror wills can be contested on the same legal grounds as any other will.
The most common reasons include:
Lack of Mental Capacity
If the person making the will did not fully understand what they were doing at the time, the will may be invalid.
Undue Influence
If someone was pressured or manipulated into making the will, it can be challenged.
Fraud or Forgery
If the will is not genuine or has been tampered with, it may be contested.
Improper Execution
A will must be signed and witnessed correctly. If it is not, it may not be legally valid.
Lack of Knowledge and Approval
If the person did not fully understand or approve the contents of the will, it can be challenged.
For official guidance, the UK Government explains how to make a valid will, including the legal requirements that must be followed.
Can a Mirror Will Be Contested After the First Death?
Yes, a mirror will can be contested after the first death if there are valid legal grounds.
However, in many cases, the estate passes to the surviving partner, which can make challenges more complex depending on the circumstances.
This is why it is important to ensure wills are properly prepared and clearly reflect the wishes of both individuals.

Example Scenario
For example, a couple may create mirror wills leaving everything to each other and then to their children.
After one partner dies, a family member may challenge the will if they believe:
- The will was made under pressure
- The person lacked capacity
- The will does not reflect their true intentions
If successful, the court may declare the will invalid or adjust how the estate is distributed.
How to Reduce the Risk of a Mirror Will Being Contested
While it is not always possible to prevent a challenge, there are steps that can reduce the risk:
- Use a professional will writer or solicitor
- Ensure the will is properly witnessed
- Clearly document your intentions
- Update your will when circumstances change
