Preliminary purchase contract and notarial purchase contract
In order to register a change of ownership in the land registers, the conclusion of a notarial purchase contract is necessary. The notary must state the Italian tax number of the seller and the buyer in his deed. Every buyer, which therefore also means the foreign buyer, must apply for the receipt of a personal tax number prior to sign the notary contract at the locally responsible tax office. To do this, a photocopy of one’s personal identity card or passport is sufficient, along with the provision of the future postal address in Italy.
One decisive difference between Italian and other countries law is that in Italy, a private preliminary contract (compromesso) is made often between the buyer and the seller prior to the notarial purchase contract.
This does not actually affect the public documentation of the conveyance of ownership in the land register, which is reserved to the notarial contract, but in contrast to other many countries is legally binding and effective for the change in ownership pertaining to land or the property.
