3.-THE PROPERTY HAS A CERTIFICATE OF NON-EXISTENCE OF AN URBANISTIC INFRINGEMENT FILE. SO, IT’S LEGAL ¡¡¡

FALSE. This certificate is issued by the Town Hall. What they do is look at the computer and certify that there are no proceedings open against that property. But it should NOT be confused with the certificate of non-existence of infringement. This second certificate is issued when the municipal technician visits the house, compares what has been built with the licenses granted and certifies that everything is legal.
Because it is confusing (and has been used to mislead more than one buyer) some municipalities have stopped issuing it and only provide a certificate of current status. This means that they will see the property and certify what is there.
