Ownerchange

An Ownerchange is free of charge and can be done with the API ModifyDomain command.

In order to change the registrant of an .AT domain you have to

1. Use the TradeDomain command in our system, or the TradeDomain function in our web interface to assign the new owner contact handle to the domain
2. Visit our .AT ownerchange form generator at http://www.domainform.net) to generate a fax form
3. Follow the instructions on the generated fax form. The update will then be processed.
4. Please note that the OwnerChange can only be executed as soon as we have received the signed Ownerchange form.
5. If you are a RegistrarOC customer, you need to activate the domain trade by using the API command ActivateDomainTrade after your customer initiated it.

Special deletion information

You can choose, if the registry should delete the domain immediately or at the end of its term with the following extension:

X-AT-SCHEDULEDATE = expiration | now 

Optional:
Indicates, if the registry should delete the domain at the end of its term ("expiration") or immediately ("now"). If the parameter is not given the domain will be deleted at the end of its term.

If you do not have the consent of the registrant you should set the domain renewal mode to AUTOEXPIRE. This will cause a so-called BILLWITHDRAW at the registry at the end of the term of the domain. A BILLWITHDRAW means that the registrant will become the new billing contact of the domain and will be charged directly from the registry for the renewal of his domain.
As the .AT registry handles domain-deletions very strict, we highly recommend to save a written confirmation of your client for domain-transactions. In case that you have to delete domains immediately, e.g. in case of fraud, the only way is to delete the domain with the API DeleteDomain command and setting the parameter X-AT-SCHEDULEDATE to "now".

Please note that you're only allowed to delete .AT domains directly if you have the signed authorization of the registrant. The cancellation-form is available for download here: http://www.nic.at/service/faxbestaetigungen/

Restore Process

To restore a domain as a RegistrarOC customer, you simply have to execute the RestoreDomain command. HEXONET directly forwards the restore request to the registry, which performs the restore in real-time. As soon as the restore is complete, the domain will get assigned to your account with the original domain data.

Please do not initiate a restore directly at the registry (e.g. using the registrar webinterface). All restore operations must be performed through our system.
