My parents made identical wills 20 years ago that state that they each leave everything to each other, if of them is deceased the estate to be split equally between myself and 2 siblings. So nice and succinct and relatively simple.
Roll forward to the present day and my mother has had a stroke and also suffers with moderate dementia. Dad now doesn't want his 'half' to go to mum, he wants to leave his half straight to his three children. His reasons are that mum will probably soon go into a care home and she will have no benefit from his 'half' whereas us children would etc.
My question is, can he legally do this? No one currently has Power of Attorney for mum, just in case this is relevant.
