How long does the child support process take?

Question Details: I am currently living with my two children's father. He is emotionally abusive and physically abusive. I know he doesn't want custody. He just says he will not ever pay me child support. I have did some snooping and have copies about 12 pay stub on top of some other info. I had to get Medicaid when I was pregnant because he would not provide insurance for us and now my girls have Medicaid. I just didn't want it to affect their insurance. I guess the main issue is I don't feel like I can leave until I feel like I'm going to get child support. I sing for a living a s only make about $20,000 a year. He has 2$ kids from another woman pays 478. Important Notice
