Just to clarify -

I want to determine the legal status of the 2 buldings before I pay any money (either to the vendor or the solicitor) - so I have not instructed  the solicitor yet.

I initially questioned the agent for some proof of what I am about to buy and he involved the solicitor (who handled the previous sale).

Another (private) message advised me that the buildings are probably legal (ie wont be knocked down) but this doesnt necessarily indicate you can legally live there 365 days a year.
