If the mother of the child will recognize that you are the baby’s father, then you and she can sign an acknowledgement of paternity which takes care of the issue. If the mother will not recognize you as the baby’s father, then you will have to file suit in court to establish paternity. You would file suit in court, contending that you are the father. You would seek a paternity test that will determine whether you are the baby’s father. Once your paternity has been established, then you can exercise your rights to visitation as the baby’s father. Admittedly, this process can be a difficult one, particularly without the cooperation of the child’s mother.
