I am in the process of buying a property extended in the 90s. As per the local authority website, there is no application for planning permission, but the building regulation application was applied in early 2000s (just before the property was sold to the current vendor) and status is 'Building Work Complete'. Is it ok to carry on with the purchase? I know the local authority wouldn't do an enforcement after 10 years of doing the work, but wanted to make sure the property is legally compliant and won't face any legal issues in future. NB: I don't want to go via the legal indemnity route anyway. Please advise
