Like all other transactions, domain deletion is also handled by the registrars. As the domain holder you need to contact your registrar and ask for the domain name to be deleted. The registrar starts the deletion process and the domain holder receives an automatic email to his contact email address to either confirm or reject the deletion. If the deletion is confirmed within 16 days from the time the transaction was started, the domain name receives "pending quarantine" status and will be deleted from the .si domain name database after 30 days.
The other possibility is that the domain holder informs his registrar he doesn't want to renew the domain name after its one year registration period. If the server at Arnes doesn't receive the renewal request and the registrar doesn't pay the renewal fee, the domain name goes into "pending quarantine" status and is deleted from the domain name database after 30 days.
Attention! The domain holder or the registrar have no right claiming back a partial retribution of the tariff if the domain name has been deleted before it expired.
