What is the easiest way to get a divorce from someone who is not willing to consent?

I have a friend who is separated from her husband and is wanting to obtain a divorce from him. She lives in Alabama has a 2 year old daughter and is also fighting for full custody of the child. The man has physically abused her constantly in the past and tormented her daughter while they were together and she left him and went to Texas for a few months. She recently came back about a month ago because he called her wanting her back (which was a lie). He is wanting custody of the child, although he had nothing to do with her to begin with even while they were in Texas. He is a crack addict and in her terms deemed unfit to father her. He has tried several times to take away the child and they both have restraining orders against each other. She has the child on a safety plan through DHR and can't be with her unsupervised until she is deemed worthy as a parent by them (has a full time job and a home). She recently went to a consultation with a lawyer and he told her that it would be cheaper on her to get him to sit down and agree to a divorce settlement out of court but he will not do such for her. It is gonna take a lot of money that she does not have to take him to court and fight him for the divorce and custody of the child. The man is stubborn and she thinks he is out to make her life more complicated. She wants to get out of her marriage as quickly and easily as possible without having to pay so much money to do so.
