When you register a domain (gTLD) or transfer it to another registrar (usually your web hosting provider), the domain will be locked for 60 days. During this period the domain cannot be transferred.
It is part of the transfer policy from ICANN and applies to all registrars. We are unable to remove the lock or make any exceptions.
Changes in the owner details
When you change the registrant name, company or email address of a domain in the WHOIS, by default the domain will also be locked for 60 days.
