Indemnity Insurance

[bullescroftr]

Our three bed semi detached house had the garage converted into a bathroom and utility room 22 years ago without building regulation by the then owner. We have have had no problems whatsoever. We are in the process of selling this property with indemnity insurance but our purchaser's solicitor has told him that this insurance is not worth the paper it is written on. Please comment.

I take it the indemnity insurance is from a large and reputable insurance company - of the likes of Norwich Union.
What exactly does the vendor's solicitor want in its place then? - retrospective Building Regs application?
