According to our Domain Registration Agreement
all the domain registrations/renewals are final, cannot be cancelled and are not refundable. Also, there is no technical possibility to change or edit domain names after registration.
If you happen to have a domain name that you no longer wish to use, please adhere to one of the following options:
3) Move your domain name ownership to another Namecheap user by selecting "Change Ownership
". To learn more about this option, you can read this article
4) Ensure that your auto-renewal option is turned off
and allow the domain name to expire.
