The new ICANN Transfer Policy has been in force since December 1, 2016. The guidelines include among others the provision that an update of the ownership data will result in a 60-days transfer lock starting from the date the update request has been accepted.
It is now possible to deactivate this transfer lock after the owner change. The former owner of the domain will receive an e-mail with a link that is valid for 14 days: The 60-day transfer lock is skipped by clicking on this link.
