Basically putting him as father on the birth certificate does not mean you will get child support and it doesn't mean he will get any kind of custody, in order to get child support you have to file with the Child Support Division, and in order for him to get custody he has to take you to court for a custody hearing, however, it does vary state to state but if there is no custody order then he could simply walk in and take your child and disappear and it will not be kidnapping....if you are worried about him harming you or your child then go to a womens crisis shelter or advocate and file for a restraining order, if you are not worried about harm then simply draw up some papers, go to the court and ask who to go about establishing full custody of your child...it is hard without being married to set it all up and I still haven't with my son's father, we work it out between ourselves...he has him every other weekend...at any time I could stop sending him and at anytime he could run off...but we do have some trust established so that helps...if you file for child support and a father is not listed then they will court order a paternity test, if he denies paternity and he is the father then he has to pay for it, if you say he is the father and he is not you will have to pay for it...but once there is a name on the certificate it is there, no changing it and no removing it, but if you do not name the father and paternity is established then they will add his name...if you are willing to go it alone and he wants nothing to do with your child then don't put his name down, that way you go your separate ways, but also if you need the support don't be afraid to file for it, your child deserves to be supported by both parents, if he doesn;t want to physically support his child then at least let the state pursue him for financial support, we have a friend who got married and 6 months into marriage his wife got pregnant and left him, she moved across the country back to where she had lived before, she told him she was home sick and was \"visiting family\", she never went home and when he flew out and showed up at her door she shut it in his face, that is when he realized she was leaving him...he fought for custody during the divorce process, he is much more financially stable than her and has plenty of dirt on her that could smear her in court, we know all of this because this in my husbands ex wife, she did the same thing to him, we even teamed with him and gave info to help his case and he still lost, he gets visitation and has to fly over 3 time zones ever couple of months just to have his daughter for 2 weeks...if he couldn't get his daughter full time with all the dirt he had against the mom then I guarantee you that an immature guy who wants nothing to do with his child will not be granted full custody, if he fights hard enough to get what our friend did then he is proving himself to be a good enough father to have the child for visitation and that will be a good thing for your child, don;t stress and worry, the court doesn't like to take kids from their birth moms, no matter how \"good\" the dad is...you and baby deserve his financial support, don't let fear keep you from it...Love Meg
