My brother bullied my 73 year old mother into signing a Power of Attorney about a year anda half ago and has abused it. She has come to me for help and I have dl'ed the form to revoke it, but it requests an exact date and we don't know that. He never gave her a copy of it and refuses to do so. She is terrified of him and won't push the issue so I was wondering if instead of the exact date we can state "at any time" or something like that. I realize we have to send him a copy of it for it to become effective, I just want to make certain that we fill it out properly before we have it notarized. This was done in the county of San Bernardino, California. Thanks for any information on this.
