I know this is a long shot, but I'm desperate for info. The father of my child told me he will not be involved, and he does not want his name on the birth certificate. I've heard different answers, but is there a way he will still be legally required to pay child support if his name is not on the birth certificate? I have tried countless times to put him on, but I don't know his ssn and current address. I live in Colorado. Thank you ladies!
