When an individual lacks the necessary mental capacity to make a Will for themselves, it is possible that a Statutory Will can be made for them. A Statutory Will looks and works very much like a regular Will. Under the Mental Capacity Act...
One of the requirements for a will to be accepted as valid is that the person who makes it must have 'knowledge and approval' of its contents...in other words, they must understand what the will says and what it means in practice.

The son of a couple who had executed 'mirror wills' contested his late mother's will. Her will, written in 1998, gave her estate to his younger brother. He argued that she could not have understood the will, which was written in English, as her command of the language was insufficient to give her knowledge and approval of its contents.
However, the Court ruled that in the absence of any evidence to the contrary or any suspicious circumstances surrounding its execution, the will should stand.
