It is your right to transfer your domain name registration between registrars. If you wish to move your domain name from one ICANN-accredited registrar to another, you may initiate the transfer process by contacting the registrar to which you wish to transfer the name.
To transfer your domain name to another registrant, you can initiate a change of registrant by contacting your current registrar. Your registrar will then ask for your confirmation via a secure mechanism (which typically will take the form of an email to the registered name holder). You must provide your confirmation within the number of days set by your registrar (not to exceed 60 days) or your transfer will not proceed. Once your registrar receives confirmation from you, they will process the transfer and notify you and the new registrant once the transfer is completed.
