Single Seat License activating for another user

Hi Team,
We have bought few licenses, but before distributing it to team we want to make sure of a thing related to Activation and Deactivation of licenses.
I m sure there is a possibility that if a license has been activated for a user (email address), it can be assigned to some other user (email address) in case the first user leaves the organisation.
Just wanted to make sure of it and if you can share the way it can be done.
Thanks & Regards,


Please reference to the article below about how to reassign single seat perpetual license to new user.
