My stepson, whom we never see (we've seen him 2 times since school started in August), lives with his mom. We've always agreed with the mom to do things "between us" and not by the court order - STUPID idea my husband agreed to long ago before I was in the picture. But it's worked for 11 years. Until now, and now we're doing things via the court order. And this means we are going to start paying 1/2 of the medical bills that insurance doesn't cover. Our court order says she has 10 days from receiving the bill, to send it to us to pay our portion. So today, we get all of these bills from her. The only one I'm questioning, is a bill from a dental cleaning that happened in December. She's sent me a bill (a PAST DUE 90+ DAYS BILL) that says we owe $107 (half of that) because insurance didn't cover it. Because it's from a December appointment, and she's apparently received bills probably every month from it, but she's just now showing us a bill from this month, do we have to pay it??? I know most people say to just do the "right" thing and pay it, but we've been fighting with her for years over the income tax that she's claimed on the odd years that the court order says we are to claim my stepson, not to mention the fact that she plans things for him every single weekend so that he has to tell us he can't come over. And she talks bad about my husband on her FB page and no telling what she tells my stepson (besides "if you ever choose to go live over there with your dad, you can never come back to me, ever!").... I just don't feel happy about sending her money like that if I don't legally have to from what the orders say. Anyone been there before and know what to do? My DH's dad is an attorney but not in family law, but I'm thinking he might be able to help give us advice but we don't like to go to him unless absolutely needed. Thanks for any advice you may have!
