Thank you so much for your speedy answer. I should have mentioned we have already been to mediation at which it was agreed that the house should be sold and put on the market by end of July 2015. A summary letter was drafted but never turned into a contact or signed. Mediation was also expensive at £500 (£250 each).
Since then my husband has changed his mind. He says he wants to buy me out but of course has been refused financing. he says he is trying to look for a job but he is passed out drunk at home all day. He has now been unemployed for 1 year and 1 month and will soon not be able to make our mortgage payments.
