The landords, like the council do not give a to55 about who else she owes, they will pursue any or all of you. Like I said you have a leech. People with bad debts/ccj's have them for a reason, it is usually because they are without Honour, they think nothing of taking advantage of "friends". You are not her friends you are the people she is currently conning for as much as she can. My adice is to get out of her what you can and then boot her ar5se down the road a piece.
