I live in California, my ex in Oklahoma. Our divorce decress says he pays half of the medical/dental bills AND requires him to pay insurance on the kids. Well he doesn't pay insurance on the kids. For the last ten years, my current husband has. Now comes the problem. My son's orthodontist bill was 4000. The orthodontists' payment clerk says the insurance that WE pay for comes off the top and crummy ex get the benefit of having it apply to his half too. I say it should be divided and the insurance's $1500 payment apply to my half. How come he gets to benefit when he doesn't pay? She says it's the law, but cannot produce anything that says that's the law. It's just how she's been trained. We're talking $750 difference here and she thinks I should be grateful he's paying anything. Told me to call my lawyer and read the fine print of my divore decree (issued 10 years ago in Hawaii and is very simply put....he pays HALF of medical/dental expenses) Who's right please? Help!
