The domain name can be transferred at any time, with four exceptions:

1. If less than 60 days have elapsed since the domain name was registered.
2. If less than 60 days have elapsed since the domain name was transferred for the last time.
3. If less than 60 days have elapsed since the data of the domain name’s owner was changed.
4. If the domain name is in the process of being eliminated.

In the first three cases you have to wait until 60 days have elapsed, while in the fourth case, the domain name has to be retrieved from the current registrar first for the transfer to be made.
