If your brother is actually stealing your mother's money, and your mother is not capable of making her own decisions, you can file a petition in court to have a judge appoint you guardian and give you control of her money. You can also start a lawsuit on her behalf against your brother to recoup what he stole, if you are appointed. If your mother is capable of making her own decisions, you can still help her to put a stop to what's going on and take legal action to recoup what was stolen. However, you haven't indicated your mother's state of mind, or capacity to make her own decisions, or whether you and she have a relationship. You mention that she abandoned you when you were 6 months old, and yet here you are trying to help her- I'm not sure why you mentioned that. Definitely need more information.
