Signing Acte Authentique via Power of Attorney

[Nathalie]

Not sure whether to stick this here or in Legal, anyway here goes.

Received a copy of the draft Acte de Vente, all seems OK, but was wondering whether anyone has added any other useful clauses in to their contracts? 

There's a clause about no comeback on the vendor if, for instance, the roof suddenly falls in or something, but there doesn't appear to be a clause along the lines of "if something goes wrong that the vendor would have been aware of, ie. faulty boiler or something, then the vendor is liable for all costs etc etc".

I saw something similar once on No Going Back, and didn't make a proper note, thinking we wouldn't find our home so quickly...

Thanks.
