We live in Chicagoland area, children in question in St. Louis Mo. My husband had two girls in first marraige, after nasty divorce and ex-wife tearing girls apart my husband did what she wanted and gave up custody. She in turn was supposed to wipe off old support owed as the girls were adopted by the new husband. Now we received notice that she is coming after him for the money. What I would like to know, is that now that they are not legally his, from what I heard, he isn't obligated for that past support, as they are unfortunately no longer his children, can someone advise what the legal point is? Thanks
