Well, it can, but probably not legally. If your mother has dementia, then she is probably incapable of signing a legal document. You need to consult with a local attorney as to the best way to proceed. I could imagine recording your power of attorney on the land records, but I am not sure that is allowed. You may have to file an action for an injunction against him. However, a letter from the attorney to your brother letting him know that you know what is going on with a threat to take further action may be enough to get him to stop.
