I put £50,000 into a relatives house (all done via solicitor) some years back , which then equated to roughly 25% of the properties value, I now need some money for a new business venture , obviously with inflation the house is worth about £400,000, which balloons my investment to approximately £100,00, am I able to make them sell to regain my money, I've held out for as long as possible and we haven't spoke for years due to bad terms, I need to know how I stand legally before I make my move, thanks in advance
