My husband and I agreed to separate and we were looking for houses for me. We rent at present but have a small property in a different area that we rent out. We were then given notice so I am moving into a small rental property with my two children and he has promised to buy a house for me and the children once he gets the deposit together. I am happy to wait a year (He earns £9000 a month so it should be doable in a year, while I earn about £1350 a month). However a friend has told me that if I let him move back into that house I will lose my right to get him to sell at a later date, i.e. if he doesn't do as he has promised and buy us a property. Is she right? Do I have to make him sell now or can I just get him to put his promise down in writing?
