make sure you get full custody of the baby cause he sounds like a jerk and yeah ask for support .. he has to pay it by law and if he doesn 't you can take him back to court and have them take the money by force if he keeps refusing
You should go to your local family court and immediately petition for child support. You don't need a lawyer, the clerk can tell you what you need to fill out. Please remember you must get child support. This isn't about you trying to get his money ;as some might like you to think). This is your child's money.
If the dad is on the birth certificate you can go to court for child support. if he isnt on the certificate you could still go to court and get child support but it would be much harder. you would have to go threw paternity and dna test. also you could have him sign all his rights over to you .
