If I were you, I'd contact the credit card companies and make sure you aren't a joint cardholder or authorized user on any of those accounts. It COULD affect your credit history, I believe, even if you aren't legally responsible for payments.
Yeah, I've dealt with a passive-aggressive spouse during divorce proceedings. He did finally sign the paperwork (I'd told him that not signing wouldn't stop anything), but it was frustrating. Your lawyer should be able to advise you.
Oh, and while you're at it, you should discuss with your lawyer the process for evicting her once the divorce is final. I have a feeling she is going to continue the non-cooperation, and you will most likely have to force her out.
