Is It Legal To Have To Pay Back Child Support On My Daughter When For 7 Years? I Didn't Know She Was Mine And The Mother's Husband Acknowledged Paternity And Is Listed On Her Birth Certificate.
I was made to pay back child support by the state Oklahoma Department of Human Services after a DNA test determined I was the father of a 7 years Old child, even though her mother's husband had acknowledged paternity by signing a notarized affidavit. Is this legal?
