Apparently my x-wife went to a XXXX in XXXX, Tennessee and had a procedure done using the old XXXX card that was only good when we were XXXX. I have XXXX papers proving that she was no longer insured after the XXXX. Now apparently XXXX XXXX shield has denied the claim but it 's showing that the charge was JOINT?? I had no knowledge of any of this and did not sign any paperwork for her or on her behalf. I only found out about the collection because I monitor my credit report from time to time. Now it has gone to collection through a company called XXXX XXXX and XXXX and is showing as a collection on my Credit Report. What do I need to do to get this off my credit and get her to stop using my card. XXXX XXXX had told me that they ca n't take the card from her and she has tried this before?? She is still using the name of XXXX XXXX and is not supposed to be using my last name anymore, the court ordered her through the XXXX to change her name back to XXXX XXXX XXXX and she apparently has not done this.
