Re: Is It Possible to Change a Will Under Power of Attorney in the Case of Alzheimer'
You need to prove mom was not mentally competent at the time of the change of the will. Having Alzheimer's, in itself, is not enough. It has to have advanced far enough so she was not able to understand what the changes were and what they affected.
You will likely need her doctors testimony regarding her condition. The aunts and uncles would help support a claim of her condition but in themselves generally not adequate to allow the courts to make a determination of her condition.
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
