I think that if he didn’t go through a clinic with legal papers, yes, he could be required to pay child support.
I wonder if guys would ever be so stupid, NOT to go through the legal process? That leads me to bring up another issue. I tend to think, that any agreement, that is written on paper, can be challenged in court. Now, it’s possible, that any prior written agreement, may or may not lessen anyone’s ability to collect anything, but it won’t stop anyone from challenging any agreement that may have been previously entered into.
I have a feeling that he does not have nearly enough money to pay any significant child support to almost 100 kids.
