What Makes a Will Invalid?
A Will can be challenged on several grounds, including failure to follow the formalities required under the Wills Act 1837. DIY Wills in particular can create risks where signing and witnessing requirements are not properly followed.
For a Will to be valid, it must meet strict legal requirements: the person making the Will and two independent witnesses must all be present in the same room during signing..
If these legal formalities are not met, the Will’s validity can be questioned, potentially rendering it invalid.
Legal Requirements for a Valid Will
To ensure a Will is valid, it must meet these strict legal requirements:
- It must be in writing.
- It must be signed by the individual who made the Will (the testator), or by some other person in that individual’s presence and by their direction.
- The individual must sign the Will in the presence of at least two witnesses.
- Each of the witnesses must then attest or sign the Will in the presence of the individual who made the Will (but not necessarily in each other’s presence).
- Witnesses must be independent, over 18 years old, and must not benefit from the Will in any way.
Failure to meet these legal formalities can result in the Will being deemed invalid.
Key Factors That Can Make a Will Invalid
There are several key factors that can make a Will invalid:
- The Testator did not have the mental capacity to understand the extent of their estate and the implications of their decisions.
- The Testator was not aware of those who might reasonably expect to benefit from the estate – even if they choose not to include them.
- The person did not know or approve the contents of the Will
- The Will was made as a result of undue pressure from a third party
- The Will was forged or fraudulent
Common Reasons a Will May Be Invalid
Lack of testamentary capacity
The person making the Will (the testator) must have testamentary capacity at the time of signing. This means they must be of sound mind and fully understand the implications of their decisions. There are four key elements to this test, all of which must be satisfied for the Will to be valid.
Lack of valid execution
For a Will to be valid, it must be properly signed and witnessed. The testator must sign in the presence of two witnesses, who must also sign in the testator’s presence. If these requirements are not met, the Will is considered invalid.
Lack of knowledge and approval
The testator must know and approve the contents of their Will. Suspicious circumstances – such as a significant gift to someone involved in drafting the Will – may lead to a challenge on this ground.
Undue influence
When a person is coerced or pressured into making or altering a Will, this is known as undue influence. To succeed in a claim, there must be clear evidence of coercion leaving no reasonable alternative explanation.
Fraud or forgery
A Will that has been forged or created through fraudulent means is invalid. Unfortunately, these cases are not as rare as many might expect.

Consequences of an Invalid Will
If a Will is found to be invalid, then the estate would be distributed according to the previous valid Will. If there wasn't a previous Will, then the estate would be distributed as if the deceased had never made a Will (intestacy).
Who Can Witness a Will?
The witness of a Will must be an independent adult who isn’t related to the person making the Will (the testator) and has no personal interest in the Will. You can not be a witness if you are the spouse or civil partner of the testor. A neighbour or family friend is usually best.
