His....? you were truncated. You have several options at this time and I think you need to seriously consider the pros and cons of all of them before you do anything. A couple of weeks is not enough time to seriously reason it all out. I will make a short list: 1. Most states are frown on fathers who do not pay the way off their offspring. Although many states do offer financial support for dependant children, they also will hunt down the father and make him pay them for any funds they gave. Lets call it retro-active child support. 2. There are ways to get around the above. That would require a court of law and he would have to be willing to sign of on all rights and claims to the child. In return you do not collect child support from him. In essence he is dead to the child. 3. You can be nasty about the whole thing and take him to court inabstentia where you sue for custody of the child and full child support, notification is sent to his last known address and there is an assumption that contact was attempted. His failure to report to court is seen as a willingness to have the court settle his part of the custody hearing for him. This takes a keen Attorney who will most likely get you a lovely deal in the process. Mind Fleeing Fathers are no longer tolerated by the Law of the Land. They are pursued, sued and even jailed in some cases. 4. You could "play nice" and hire a detective to locate him and serve him and play the "cater to his needs" game. However this means that you will most likely get hurt in the end. As for his signature - unneeded. No, he already signed, its that signature is found in the genetic code of the child. If he wants to decry his being the father, modern DNA tests settle the question quickly and with little doubt. In all honesty I would advise you to pursue every and all legal means to get full single custody of the child while sueing the biological father for full child support. That would include no visitation, and no "rights" to the child for him. He choose to run at a critical time in your and your baby's life. He made this choice to be as far from his duty as possible leaving you to agonize over pregnancy and the future. This is a person who is very selfish and does not deserve the title of "dad" from the coming baby. As for the name, Give the child your maiden name. I frown on men who run from responsibilities. Sounds to me he is running as fast and as far as he can. To me that tells me he is a coward, not a man at all.
