PLease help - advice

Dear all, I hope that somebody could point me in the direction.

I split up with my ex-partner (we were never married) two years ago. I had to go to great expense, however successfully was granted an order of sale. My partner and her two children aged 16 and 18 were allowed to reside there until sale.

My ex partner did every thing she could to prevent the sale, leaving the house in bad order, not allowing viewing by being obstructive etc.

I could not release her from the mortgage because of my credit rating (defaults etc) and the house was not selling. I begged the building society with no avail.

I have paid now paid her several thousands pounds to leave the property, it was my only option without paying a fortune at court again. She has been released from the Deeds (which she agreed too) but NOT the charge on the property. Our mortgage company would not allow this etc.

I know want to rent the property out to start repaying some of the debt, the mortgage is interest only. The building society says that this is fine, but require BOTH our signature.

Just to be difficult, she is refusing to cooperate and make any contact.

Is there any thing I can do, if necessary by the court to secure this?

Any help would be gratefully received.

I'm afraid nothing springs to mind here. The only chance its some sort of order arising from the previous order - a new order as to the means of implementation of the old one. I'm far from sure it would work, though.
