We are in the process of buying a 1980s house. Kitchen/Dining room was separated by an archway and there is building regs approval for an RSJ, all fine. The vendors then extended that RSJ by about 10 inches to make the archway wider to fit a bigger table. They had a structural engineer calculate and sign off the work but didn't get building regs for it as it was a small change and didn't affect access through the house etc.
Is this right? We're not far from exchange. My solicitor wants them to buy indemnity or do regularisation. They aren't willing as they say its stucturally sound as proved by the structural engineers report. I don't have that much faith in my solicitor tbh.
