When I attend the creditor meeting, can I say she never made payments and it was through my business, so technically this is not her debt?

My ex-wife is filing for chapter 7. She was awarded in the divorce, payment of a HELOC on a second home we owned that went into foreclosure. I was awarded our main house, which was quitclaimed over to me but I cannot refinance the home into my name only because my name is still on the HELOC, which she was supposed to get my name off. So, the home which was quitclaimed to me is listed as her debt also on her bankruptcy, she has never made any payments on this. I am self-employed and at the time we were married the business was owned by both of us, now just by myself. I will be attending the creditor meeting, but I need help in what I need to ask at the meeting, what I can do to get the house refinanced out of her name and how.
