So we were close to exchange on a house we're buying when I (not my solicitor) noticed there was no building completion certificate for the extensive renovations completed in 2018 by a previous owner showing up on the searches. The house is being sold following probate by a beneficiary living abroad. Even the guy who died never lived there. The vendor/their solicitor is offering an indemnity policy but it would only cover us against enforcement action by the council and not remedial action if it turned out to be needed. They have refused to actually check with the council if there is a certificate in existence as this would invalidate the insurance. My solicitor has not given any advice on this other than to tell us the terms of the policy and ask if this is acceptable to us and would we like to complete next week. We have said we won't proceed until they have ascertained whether there is one and got one sorted if there isn't. Is this what you'd do? We can't afford to proceed however if it goes beyond end of March due to stamp duty offer ending.
