Which leads us back to the disclaimers that appear on EAs' websites, documentation and emails. "We are not responsible for inaccuracies, don't believe a word we say, etc" I'm not saying they should be exonerated from outright lies or deception, but there are limits to their responsibilities with regard to information. Also, always remember, the buyer has no contract with the EA, the only contract is with the seller.
So what responsibilities, if any do EAs have to purchasers?
What about having the sellers' solicitors provide the EAs with copies of deeds, land registry entries, detailed maps, proof of title and the EA cannot advertise the property for sale without these? If the buyers' solicitors verify that all is correct, the sale can proceed with the costs added to the buyers' bill, other wise the seller is stuck with them.
What about extending the Sale of Goods and Supply of Services Act to real property?
