I am buying a house and the seller says that the plans for the house have been lost by the council. The selling agent has agreed to have new plans drawn up, but I want to understand the risk that I am taking on by buying this house. The way I see it is thus:
1) If the plans are lost, new plans will have to be accepted by the council so there is no issue.
2) If they manage to find the plans (on microfiche, or some other archive), and those plans match the existing structure, there is no issue.
3) If they manage to find the plans (on microfiche, or some other archive), and those plans DO NOT match the existing structure, there is an issue. It is this scenario that I need to understand. What is my risk here? I understand there is possible punative action (I understand it to be a fine and/or being required to demolish parts of the house that are not on the plans).
Can you help me understand the risk here please? What are the size of the fines? How can I protect myself? The seller has moved countries and cannot solve this problem, so will sell the house without plans. I am okay to accept it in any scenario other than this scenario.
