Hello and thank you for the opportunity to assist you. My name is ***** ***** I will do my very best to answer your legal questions.
No, there is nothing that the family can do about the situation. It is up to your brother alone to deal with the situation. Only he has the standing to fight the restraining order. In order to do that, he would need to file a motion in the court to have the restraining order dissolved. He'd need to argue that he has done nothing inappropriate, and he'd need to convince a judge that he is telling the truth and that his wife and kids are lying.
I hate to say this, but it does sound like he'd have a hard time convincing a judge of that. After all, it would be his word against 3 other people. Also, a judge is going to favor keeping the restraining order in place because if the judge is going to make an error, he'd rather make the error on the side of caution with regard to the children so that they are protected. The worst case in that situation is not as bad as the worst case if he were to lift the restraining order and then it turns out the wife and kids were correct and something bad happens. So, while your brother can fight the restraining order, he would have to be quite convincing to have the order dissolved. Not impossible, but difficult.
