To change the Admin-c there is no additional cost.

In order to change the Admin-c of a .it domain name (if the domain is registered with ARUBA-REG) you must send the following information to Aruba, by fax to the number +39 0575/862000 or by opening a Ticket
from the Aruba Support
section:  

We also remind you that, if the Certified Email service has been activated, the new Admin-C must send Aruba, together with the rest of the information, the application Form for the Certified Email service duly filled in and signed.

Aruba reserves the right to request further documents  (Company registration certificate, company statute, notary deed, etc...)
in order to verify the identity of the persons involved.

IMPORTANT: Please enter the new email address in the form in BLOCK CAPITAL LETTERS. If the details entered are not clear / correct, the request may be rejected.
 

**So that the documents are accepted, they must be duly filled in and signed by the New Owner.
