The man on my child's birth certificate isn't the father but has accepted since birth
I was in a relationship of 4 years and cheated with another man and got pregnant, the man I cheated with knew I was pregnant but the guy I was in the 4 year relationship knew the baby wasn't his but we still stayed together and he was there for the pregnancy and the birth and signed her birth certificate. She is now 9 months old and the man I cheated with wants to take me to court to get his rights and his name put on my child's birth certificate but he was never around while I was pregnant or even after she was born and never offered to step up and be a father and that's why the man I was with took the responsibility. Can the other man now 9 months later take me to court and make me do a DNA and have his name out on the birth certificate when she already had a father who has done everything for her since birth. I live in the state of Missouri
