I dont know about your state but in MI and PA you can do the divorce yourself through the courts. You may be able to go to the library and get the papers or have to buy them through a 3rd party, my papers in PA were $25 dollars and then I pd 145 to file at the court house. There will be insturctions with the paperwork and proly a number for legal aid that can answer your queastions.
As for child support and custody if I were you I would want something done legally protecting your rights. I obviously dont know your husband and what he would do but right now I dont have anything legally done for child support, my ex gives me money but he doesnt have to and Im scared if he gets mad at me or if I start seeing someone else he will cut me off! I dont have money for a lawyer but you really dont need one. If you call your local family court they can give you the number and the state will help you do your child support. I also know that in PA you can do your custody like that too. That is obviously all uncontested but at least it would make it legal and put it into writing to protect you! If he did fight any of it then you would proly need to find a lawyer. Good luck, I am going through a divorce right now with 2 kids and 1 almost here and it isnt easy!
