What is the name of your state (only U.S. law)? California The man I was with (Steve) while pregnant to my daughter signed the paternity papers and the birth certificate at time of birth but has been out of the picture for 5 years. The possible real father (Josh) wants to get a paternity test done. He also has not been in the picture for 5 years. If It came out that he (josh) was the father, what kind of rights would he have. Would he have to pay back child support or any child support that (Steve) owes, even know Steve was the one that signed the paternity papers. Would he have any financial obligation?
