Help! My sister is buying a flat at the moment, not exchanged yet. The lease floorplan shows a 1 bed flat but a second bedroom has been carved out. The sellers refuse to get retrospective landlords consent and have said they will take out indemnity insurance instead. Solicitor says this is not a 100% guarantee that my sister won't have to pay anything... What would you do? (And haven't even touched upon building control and planning!)
