Building Indemnity Insurance

[pmakwana]

Im am in the process of buying a new property and amnearly in a position to exchange contracts. However there was a enquiry raised by the solicitors. The house has an extension which was done to the rear over 20 years ago. Apparently, there is no building regulatons or the back wall. I have been told by my solicitors that I will have to take out indemnity insurance for the back wall. Can someone tell me what this insurance is? How much it would cost? and why I should have this?

Thanks

It could be a Defective title indemnity, meaning that there could be a defect due to the lack of planning permission - the back wall could have been built on Common land for example and there could be rights of way that have been blocked as a result of the building of the wall.

As regards premiums, should be a minimum premium, although minimum premiums on these types of covers could be �250 or so ?? worth giving them a call.
