Thank God for overpriced lawyers!
When you buy a house in Britain, there is an extensive and well-established series of checks you must perform to ensure the property is suitable for habitation. When undertaking a survey, you should ensure that the boundaries of the property conform to those recorded at the Land Registry, and that the property does not lie on a flood plain or risk structural damage from coastal erosion or subsidence. Unfortunately, there seems to be no mechanism to protect householders from the worst possible eventuality — which is to find out that you have a lawyer living next door.
