Hi i have a few questions. How do i get full custody of my child or to get the father to sign over his rights. What form is needed for him to sign his rights over. And does the child have to be born before i can file for full custody?

Yes, you have to wait until the child is born.  Then you would have to file for custody with your local court.  You should consult with an attorney regarding your situation as custody is often a complex issue and an answer here would not be enough to properly inform you of your rights and responsibilities, as well as the particularly process in your county.  There are many attorneys who offer free consultations.  Go meet with one.
