Does any one know anything about the laws regarding naming of an infant? I would like to give my unborn child my last name(I think it would be easer for my child as well as for me); however, the father wants the child to have his last name. We are not and have never been married. I will sign an agreement of paternity, because we both agree he is the father. When the birth certificate is being filled out do I have the legal right to give my child my last name if he is adamantly against it?
