Hi, A decade ago my friend was trying to buy a flat but couldn't get a mortgage on her own. I offered to be the other name on a joint mortgage so that she could buy it. We got a joint mortgage. She put up the entire deposit for the flat, paid for everything when it was being done up etc. We lived there together at first but soon she moved elsewhere and rented it to me and other tenants. I claimed several years of housing and council tax benefit as a tenant and not as an owner when earning almost nothing at all. Our agreement had been that, as I was putting in no money, etc, I would not be a part owner. I have received an Interview Under Caution letter as the council "have information that suggests I may have been part owner of the property which was not declared when claiming the Housing/council tax benefit." What should I do? Will my name on the mortgage mean that I'm f**ked even though neither of us view it as my property? Help. I'm very frightened.
