Looking for some lawyerly input.
My PIL (really FIL) are updating their wills. MIL has Parkinson’s, and dementia. Her understanding of what’s going on changes from day to day. I personally don’t think she has capacity any longer, but it’s not my call.
FIL has no neurological conditions, and is in good health. However - speaking bluntly - he’s just not clever enough to understand the implications of or the wording in the draft will that the lawyer has sent. He gets confused very easily, has very little “book learning”, cannot understand sophisticated or legal language. The intricacies of “ if this happens, then that happens and this means that this other thing will happen” are just beyond him. DH and DSIL are going over it with him over and over again to try and be sure that he knows what he is agreeing to: they don’t want to be accused of misleading him, further down the line. Throughout their married life, MIL was the administrator and he did very little of this.
My question is, from a legal POV how does the lawyer decide that he is able to sign a new will? There’s no medical reason why he shouldn’t understand, and he’s not that old (70’s), but his brain just doesn’t work this way.
