I have been there myself. My first husband and I had children together. When I had left him, I had no money for a lawyer, but he did. My fear level was very high. But I found out that I could get help from the state to obtain a good lawyer for nothing. (I did end up winning custody so they were very good, and our divorce lasted a year and everything was covered).
It would be a good idea for you to contact your local welfare office (they always have the information there) and tell them your situation. More than likely they will be able to direct you in the right direction on where to go for this sort of help.
Good Luck
