Divorce was finalised in summer. Initially thought that house was worth 350 and had paperwork in bundle stating this, then Zoopla estimates suggested 400. Judgement was made that 120k is ringfenced for me as DC plus older disabled child from prev relationship live with me. ExH gets 'up to' 50k then anything over that is split 50/50. House now not not likely to sell for more than 375k. House was bought with a 90k deposit from my parents, he contributed nothing; in hindsight I can see this was very stupid and he was a cocklodger. Ex has dragged his feet this whole time as he is the one in the house (long story) and house prices have gone down round here even in last few months. Court order states that house to be put on market immediately but we have to agree on sale price. Ex is refusing to sell unless I put in writing that I will give him 15,000 once house sells. He is saying he will take me back to court unless I agree to give him this money. I have no idea what to do; he has dragged me through the courts for years regarding the DCs, reported me vexatiously to police constantly, and made 12 separate referrals to social services (all NFA). He is LiP, I have borrowed money from family to pay for lawyers till now but nobody can afford to lend me anymore. I honestly feel like I am losing my mind. Any advice gratefully received thank you
