DNA was done for my 7 mth old son, boyfriend is not the father, but wants to stay on BC. I need to know which is legal binding doc in case of brk up.

 Technically, in order to legally establish paternity,  one has to file a Petition to Establish Paternity with the court.  If he had filed for paternity and you did not contest it, and nobody had a paterniyt test done, then he would have been established as the father. If you put his name on the birth certificate, but he did not sign it, that does not legally establish him as the father.  Had he signed it there would have been a presumption of paternity, but that could be rebutted with the DNA test in court. Since he has not had a court adjudicate his paternity, he is not seen as the father in the eyes of the law.    So, technically, if you break up, he would not have parental rights,  And if he tried to pursue these rights, the DNA test would show that he was not the biological father.    I hope that helps.  And happy Mother's Day.
