You have asked us to advise you of the current law for each state in Region V regarding
                  the appearance of the father's name on the birth certificate of a nonmarital child.
                  Specifically, you have asked us to determine whether state law requires either the
                  father's written consent or a court determination of paternity before the father's
                  name can be entered on the birth certificate of a child born out of wedlock. You have
                  also asked us to determine whether state law requires the father's written consent
                  or a court determination of paternity before the birth certificate can show the child's
                  surname to be that of the father's. Our findings are as follows:
               
               In Ohio, the father's name can be entered on the birth certificate of a nonmarital
                  child only if both the mother and father sign an acknowledgment of paternity affidavit.
                  OHIO REV. CODE. ANN. §§ 3705.09(F)(2), (G) (West 2001). Thus, the father must give
                  his consent before being named on the birth certificate, if the child is born out
                  of wedlock.
               
               If a man is found to be the father of a child pursuant to an order of the court and
                  documentary evidence of that fact is submitted to the department of health, “a new birth record shall be issued by the department of health which shall have the
                  same overall appearance as the record which would have been issued . . . if a marriage
                  had occurred before the birth of such child.” OHIO REV. CODE. ANN. §3705.09(G); see also OHIO REV. CODE. ANN. § 3111.18 (“upon the order of a court of this state . . . the department of health shall prepare
                  a new birth record consistent with the findings of the court and shall substitute
                  the new record for the original birth record.”). Thus, a court determination of paternity would alternatively be required before
                  the name of the father could be entered on the birth record of a nonmarital child.
               
               As for surnames, in Ohio, the father does not have to provide his consent before the
                  nonmarital child can take his surname. Rather, the child is registered by whatever
                  surname the mother chooses. OHIO REV. CODE. ANN. §3705.09(F)(2) (“If the mother was not married at the time of conception or birth or between conception
                  and birth, the child shall be registered by the surname designated by the mother.”). There is no provision in the Ohio statutes regarding the designation of a surname
                  if paternity is established by an order or judgment of the court.
               
               CONCLUSION
               These are the current requirements for the appearance of the father's name and the
                  child's surname on the birth certificate of a nonmarital child in each of the six
                  states in our region. As requested, we have appended a chart detailing the above information
                  and effective dates for your use.
