So I'm currently separated and will need to get a place of my own. (Currently moved back in with my parents) Me and my wife have a mortgage together on a house we bought 10 years ago. It sounds as though her dad is happy to buy me out. Now I know the house needs valuing and then you would subtract what's left of the mortgage from this then half it. However. Because the house isn't being sold and I am only removing the equity, in Theory she could sell the house, pay what's left of the mortgage and be left with a much larger sum to put down on a different property. For example, if the house was valued at £200,000 and there was £80,000 mortgage, I would get £60,000 but she could sell the house 2 months later and be left with £120,000. Now please correct me if I have this completely wrong but how is that Fair?
