What is the name of your state? Illinois. My husbands son turned 18 in january of 2006. (he just turned 19) We still have two minor children that we are responsible for the medical expenses, but this one, we were no longer responsible when he turned 18 (per the divorce agreement, which says our obligation automatically terminates). I had a pharmacy bill show up with charges from him included, wrote the pharmacy a letter, they removed his charges and sent a new bill. not a problem. The doctors office, however, is another story. He has two hundred dollars in charges from going to the doctor, and they are on the same account as the minor children we are responsible for, and the doctors office refuses to remove the charges from our account and bill them to him. I wrote them a letter two months ago, new bill showed up, charges still there. I wrote them another letter last month, included a copy of the divorce agreement this time, just got a new bill, charges still there, so we called them. The billing lady says she "can't" remove them, because she doesnt have an address to bill him. (I have given it to them in writing for the last two months). We gave her the address to bill him, she still won't remove them. She said all she can do is send him a bill too, with the minor childrens charges on there. Does this make any sense? She want's to know why we can't pay them and seek reimbursement from him. We aren't their collection agency. Is this legal what they are doing? How do I get them to remove the charges we are not responsible to pay? This is the only office I've had this problem with. The rest have cooperated. This office refuses to remove the charges and bill him, and I don't understand why they can't. One of these charges is from september, and is putting the account in delinquent status.
