Challenging a Will in Probate on Grounds of Mental Capacity (Dementia)
In Catling v. Catling, the 2007 will of Mrs Catling was declared invalid due to her lack of mental capacity caused by dementia. The court found the 2007 will was a radical departure from her earlier wills and that she did not understand the changes. Medical evidence was pivotal highlighting necessity of mental capacity for a valid will, per Banks v Goodfellow (1870).
