Generally, if the parents are unmarried the mother has sole custody and control in most states until the father can establish his paternity. Remember, a child's mother can always be identified by medical records. Since the father didn't give birth and he was not legally married at the time of the birth he must establish his paternity by signing the birth certificate at the time of birth (waiving DNA testing rights) which must be done with mother's consent. If he doesn't sign the birth certificate then he must seek another way to establish his paternity and that is done through a DNA test. A paternity test can be arranged through the court. Once paternity is established in court, the father can request visitations or custody through the court. If the mother retains physical custody she can request that the court issue a child support order. If the father gets physical custody he can request a child support order.

In most states the biological mother of the child, the husband of the biological mother because he is the presumptive father regardless of whether he was involved with conception or not, and any putative or possible fathers that the child may have whether married to the mother or not. It is important to discuss this issue with either a family law attorney or the agency responsible for child welfare, as there may be time limits on how long a person has to file a request to determine paternity. For example, in IL the mother may request that a potential father be tested at any time from birth to the child's 18th birthday, when the child can then make a request themselves; but a potential father only has 2 years from the date of birth to make a request, and only one year to sign the birth certificate if they did not do so at birth.
Yes, it is possible to request a DNA test after signing the birth certificate, but the process and requirements can vary depending on your jurisdiction. If there are doubts or concerns about paternity, it is advised to consult with a family law attorney to understand the legal procedures and options available in your specific case.
