A Notaio is legal professional, an expert in law, as is a lawyer. Neither is an expert in construction. They do not visit a property. They do not verify a property has all the appropriate permits in place. A Notaio will take statements to this effect from the seller and will include them in the sale contract. The law does not require more. Performing a building inspection and verifying building permits is the domain of a technical professional such as a geometra or an architect. In a few limited parts of Italy, such as much of Tuscany, the Notaio will ask for a sworn technical compliance report from a technical professional.
