my mother has dementia and both my parents wish to update their Wills to include a discretionary trust for my brother. We informed their solicitor of my mothers diagnosis and he immediately said that my mother can no longer update her will without proof from a doctor that she has the mental capacity. It seems to me that instead of my mother being supported to make her own decisions she now has to prove that she can first. I would have hoped that a solicitor could use their judgment to check that my mother had testamentary capacity to ensure she knows what she is signing as opposed to having to provide a certificate from a GP. The solicitor has not spoken with my mother at all before reaching this decision. I am wondering if I have misunderstood the requirements of the mental capacity act
