I'm not sure what you are asking here. You can't do much to stop your brother from being cocky and nasty. If your mother has capacity, she can change her Power of Attorney, and she can choose whether or not to listen to him. If she does not, for example, if she has dementia, you could petition the court to have the current Power of Attorney revoked and be appointed guardian of her.
