Once a domain name has been successfully registered on your behalf, you will be the owner of the domain for the duration of the registration period (one year). You can extend your ownership by renewing your registration yearly. For any domains hosted with 1&1, renewal of the domain is done automatically on your behalf using your payment details and the current domain registration price (if it is not an included domain). The current prices for all types of domains are found on the 1&1 Domain Price List.
You will be notified via E-mail when your domain's expiration date is approaching, as well as instructions on how to cancel a domain if you wish to let the domain expire.
