Registrars may (but are not required to) allow registrants to opt out of the 60-day lock prior to the change of registrant request.
To transfer a domain name to another registrar and change the registrant's information, registrants may:
Request the transfer to another registrar before changing the registrant's information (to avoid the 60-day lock); or Have the prior registrant opt-out the 60-day lock (if this option is offered by the registrar) before making any change to registrant information.

What is a 60-day transfer lock?
Under the existing transfer policy, if you transfer a domain, it will be locked for 60 days. This is an ICANN policy so it affects all accredited registrars and domains—and is not specific to only Name.com. We are unable to lift these locks or make any exceptions.
The new policy introduces a 60-day period in which your domain is locked when you change its contact information, unless you specifically opt out. When you make a contact change, we will now give you an option of opting out of the transfer lock. If you opt out you do NOT have to wait 60 days before you can transfer the domain.
60 day window requirement
ICANN prohibits domain transfers within 60 days of a change to the WHOIS data or registrar of a domain. If you modified your contact information, transferred registrars, or registered your domain in the last 60 days, we will be unable to process your transfer immediately.
You can continue to leave the domain “In Progress” and we will continue to attempt to process the transfer until the 60 day window passes.
