We are in Scotland and I'm asking on behalf of my parents in law. We will chase up with a lawyer as well.
MIL has Parkinsons and dementia. She and FIL made wills 20 years ago which are now out of date. They are simple mirror wills but need updated, so I think a codicil for the changes would be sufficient.
My question is: FIL has Power of Attorney for MIL, who no longer has the capacity to read, understand and sign the codicil. Is he able to sign the codicil on her behalf? even though he's the one who will benefit from her will etc?
Thanks for any advice.
