In the UK, we are free to leave our assets to whoever we like, subject to certain safeguards. However, it may be possible to contest a Will on one of the following grounds:
Lack of testamentary capacity
For a Will to be valid, the person making the Will must be of sound mind and be able to understand the meaning and effect of making a Will, the extent of their assets, and the consequence of including or excluding someone from the Will (referred to as testamentary capacity).
They must not suffer from any “disorder of the mind” which may cause them to make gifts that they otherwise would not have made.
A Will may be open to challenge if one or more of these requirements are not met.
Lack of knowledge and approval
A Will can be disputed if the testator was not aware of the contents of the Will or did not have the knowledge required to approve the Will. This can happen if the Will is very complicated, if the person is very ill, hard of hearing or unable to read.
Undue influence
A Will can be challenged if the testator is unduly influenced or coerced by someone into making or changing a Will in their favour. The pressure must be such that it overpowers the testator’s own decision-making.
Fraud
A court can invalidate a Will obtained by fraud, for example if the document or the signatures were forged, or if a person was deceived into making a Will.
Incorrect execution
A Will is a formal legal document and must comply with section 9 of the Wills Act 1837. For a Will to be legally valid, it must be:
- in writing
- signed by the person making the Will (testator), or by another person in their presence and by their direction
- in the presence of two or more independent witnesses present at the same time, and who must attest and sign the Will
A court can set aside a Will that has not been properly executed. The result would be to revert to an earlier properly executed Will if there is one, or intestacy.
