But as you said "reregister their name officially at a certain age" then it has to be done by deed poll the other way "just telling people you want to be called a new name is not "official" and would not be registered.

"Most people use deedpoll when they are divorcing and want to go back to their maiden name or things like that."
I know about 8 people who have changed there name and not been married they just changed it because they did not like there old one.
