Answer
A Will can become invalid for a number of reasons. For instance, if it hasn’t been signed correctly. It needs to be signed in front of witnesses and the witnesses also need to sign it themselves in order for it to be valid. The two witnesses must also be over the age of 18 and must not be beneficiaries of the Will.
Another issue that could lead to your Will being invalid is if you do not have the mental capacity to understand your actions when writing and signing the Will. Similarly, if you were under pressure or did not create your Will voluntarily, this could also result in it being invalid.
If your Will is invalid, it will affect your beneficiaries and could result in your estate being distributed according to an earlier valid Will. Alternatively, if another Will was not made, your estate will be distributed according to the Rules of Intestacy which may mean that your intended beneficiaries will not inherit from you.
When making a Will, you should consider seeking advice from a qualified legal professional, such as a solicitor, to ensure that it is legally binding and no mistakes occur during the process.
