Call the Office of the Attorney General and they can help you with this question. They can also file any paperwork needed to start getting support. A legal separation is almost as expensive to do as a divorce and then you may have to go back and do the divorce (hopefully not). You can get answers to a lot of child support questions on the Office of the Attorney General's Child Support Division website. Let me know if you need help finding it and I'll try to get the link for you.
