What is the name of your state (only U.S. law)? I am from Louisiana, am writing this on behalf of my husband. My husband was previously married to a woman who had 2 children (these are his stepchildren). Because she was unemployed, he carried insurance. My husband's insurance was better, so she insisted he carry insurance on her kids. She left him in July 2009 which is their legal day of separation. Approximately 2 weeks after the legal day of separation her daughter (who was not living with her at the time though the ex has legal custody....daughter was living on her own, working, out of high school, living with a friend) went to see a physician. She failed to pay any sort of co-pay. In addition on the account was a previous balance which the ex had failed to pay also as a result of not paying the co-pay. Anyway, when the daughter went to the appointment, the current billing information was not updated. My husband was still carrying her on the insurance. Several weeks later the ex contacted my husband about insurance, begging him to keep them on. He reluctantly agreed but did so for fear that the stepchildren would be uninsured but told her he was not responsible for their bills. She verbally agreed. Many months later as the divorce was being final (they had only 6 month wait), he started receiving bills which he ignored. 6 months after that at which point we married, still receiving bills so I attempted to deal with it for him. I placed a call to the physician's office and explained to them the situation. The office manager told me per HIPPA she could not discuss it with me. So finally the ex called him for something and he told her about the bill. She told him to send them to her and she would take care of it which I did. Yesterday we received a card from her in which she very ugly and very adamantly stated that my husband needed to man up and pay the bill that it was his responsibility. I disagree and so does he. We feel that legally it is hers. Are we correct?
