Is it likely that a non-biological, noncustodial, non-father figure would be forced to pay retroactive child support?
My boyfriend and his ex got divorced when his daughter was 3 (his name is on her birth certificate) and his ex wouldn't let him contact his daughter. He hasn't acted as a father towards her or supported her since she was 3 and she is 17 now. His ex has recently filed for retroactive child support for the last 13 years and been awarded it. My boyfriend has always thought that his daughter wasn't his and that the biological father is his ex wife's current spouse and the man she cheated on my boyfriend with when they were married. The current spouse has raised my boyfriend's daughter for about 14 years. She also tried to pass off her second child as his, when it's her current husband's.
Would it be likely that he wouldn't have to continue paying back child support for her if this is true?
