Complete a manual Change of Registrant (CoR) application for a .au domain
This guide will teach you how to complete a manual Change of Registrant (CoR) application for a .au domain registration
A manual Change of Registrant (CoR) application is required when the domain registrant of an AU domain is not eligible to hold the domain name because the ABN/ACN has been cancelled.This commonly occurs due to changes in business ownership, the business was restructured, or has been rebranded and is operating under a new business name. Regardless, keeping your domain registrant information current is a integral part of ensuring your business is eligible to hold that domain name license.If you have been notified that you are not eligible to hold your domain, you must act immediately to prevent domain suspension, or deletion.To complete a CoR, an application must be submitted to the registrar which includes documents verifying the change that took place.You will need to ensure the new registrant nominated is eligible to hold a AU domain. For further information on the eligibility required, please read our guide on Eligibility requirements for .au domains.Note, a manual CoR is only required if your registrant ABN is cancelled. If the current registrant ABN is active, you can submit an automated CoR within the Client Portal, navigate to Domains >> My Domains >> from the right hand drop down menu, select Manage the domain.
