I purchase a Listing pro theme, but my client does not pay me regularly, so I want to change my license to another domain, is it possible Pls give me any suggestions.
license purchase envato market just one time payment for lifetime.
Just my personal opinion: then why you would like to unregister the license from your client website because of client not paying you regularly! if the client pay you for theme license then client can use the license. if you mean payment for website development then that is other thing then the theme license issues.
Now answer your query: yes it is possible but for doing this you have to unregister the license first then use it to another website and in some cases may need to contact theme author about the license issues.
