Ex currently isn't working, and living with family, claiming universal credit. Neither of us want the FMH, which I currently live in. They've said they won't agree to the sale of the house, as this will impact on the UC claim (probably £100k of equity). Can they do this? They don't want the house sold until they have stable employment. The house is costing me a lot more than alternative accommodation I could arrange, and I feel like I'm being held hostage by their demands.
