Ohio. I was lied to about conception date, and signed an Acknowledgement of Paternity Affidavit (which is supposed to be for unmarried mothers ONLY. She's married, I am not) thinking the child was mine. Now the child is 1 1/2 years old and looks identical to the other potential biological dad (a family friend who stayed with us and impregnated the mom while I was at work). Neither of them mentioned they had sex, and I was told I was the father (even though we used condoms). The mother was/is married to an additional male that should have been presumed father, and should have been on the birth certificate. Now child support is coming after me, and I just recently realized the child can't be mine.I am petitioning paternity through a DNA test, and was told it is already established by an incompetent customer service rep for the county, even though another rep sent me the form and said I could. This is paternity fraud, and I was told it has to go to the juvenile court. I am going to contact a caseworker tomorrow, and need to know my rights. Is it plausible to make the biological dad pay, instead of the me (the one lied to)?
