This doesn't answer your question, but you should also be aware that the divorce laws are different in each state. In some states, if you are married over ten years and are eligible for alimony, the spouse may have to pay alimony for her lifetime. If it is less than ten years, the judge determines based on the number of years she is married. Also, if she begins to earn money, the spouse may go back to court and ask the court to reduce what he has to pay in child and/or spousal support.
Before filing for divorce, it would be important for her to speak with a family lawyer. In many cases, the court will award her attorney fees. Some courts give free assistance in helping to fill out forms and other types of help, including workshops, etc. She should go on the internet and check out the court's websites in her county to see what type of help is available to her, if any.
I live in San Francisco and once a month, they have free legal advice from volunteer attorneys. I went one day and they had 17 attorneys and they matched you up with an attorney in the field of law you needed - immigration, family law, real estate, etc. They also had Spanish and Chinese speaking attorneys there. They didn't end the session until they met with everyone who showed up. The lawyers that volunteer can be very good and experienced as a lot of law firms encourage pro bono work and they get credit for it at their firms. There is another program here where you can have an initial meeting with an attorney for $25. What I am trying to say is that there may be very low cost and free help to at least get her started and pointed in the right direction. They won't represent you but if you have a few questions that you need quick answers to, it can be helpful. Often attorneys give 20 minutes to one hour free consultation so you can determine if you want to hire that attorney.
If she were interested in any of the above, I could try to find out on the internet if any of this help is available in her area. I would just need the city, county and state she is living in.
