Jolly Rats, Good advice but ex-parte is not an order, it simply means a hearing without the other party being noticed. These are used to get a temporary order because the injury to the person needs immediate relief.
Getting an attorney is wise. However, she has zero money. She needs to be taken to one of the local free legal services in her area. She should start by asking at her church or call the court clerk for a list. Ultimately he will have to pay for her attorney as well as he has as the the money. This case sounds to me like he may be broke and realizes he got in over his head. In that case she has a serious problem and should see social services for help and advice.
If he is not broke, then it could be matter of the girls being terrors and the mom not controlling them. This happened to me with my first k-1 who also had two daughters. Fortunately, I did not make the unwise decision to marry first and ask questions later as what seems to have been done here by one or both parties.
