My question involves name change laws in the State of: OHIO
My fiance has an exgirlfriend who has a child. At the time of birth he was told the child was his. His name is NOT on the birth certificate and paternity tests showed he is not the father. The child still has his last name. We have contacted the mother and told her she needs to change the last name and she is unwilling. Doesn't he have some right to his own last name that forces her to change the child's last name?
