Conservatory Restrictive Covenant Help

Currently in process of buying a 3 bed house. We’re 4 months in and fed up to be honest. A issue around a Restrictive Covenant has emerged.

House was built around 1981, I gather it was council land and the deed stated any extension needed on property would need a license from the council. In 2006 a conservatory was built by the sellers.

Our solicitors asked their solicitors did they get a license for the conservatory. They said yes. My sols chased their sols for them to give proof of this. But she declined and their solicitor said we should take out indemnity insurance and they will foot the bill.

But my sols says this is incorrect, as she’s declared that she did get licence that means we can’t get indemnity insurance.

So where does that put me?. My sols said if they won’t provide proof they will have to tell my lender and go from there.

But tonight she’s saying, actually we could be taken to court, or asked to take the conservatory down or issues down the line again if we decide to sell.
