Quick answers
Do I have to change my name when I marry?
Only if local law or household rules say so. Japan’s koseki has required one married surname; many other systems make change optional.
Is a deed poll enough everywhere?
The UK deed-poll path is not a universal solvent. U.S. states, Germany and Japan each have their own instruments.
Did immigrants gain by Anglicising names?
Biavaschi, Giulietti and Siddique found some historical U.S. earnings links after Americanisation — a description of a biased market, not a duty.
Will a new name erase the old one online?
Rarely. Data brokers and news archives keep the previous string. Plan for coexistence.
Is changing a child’s name easy?
Usually harder: both parents, a court, and a welfare test (explicit in German Namensrecht).
Does a nickname need a legal change?
Only when institutions that require the legal string will not honour a used-name field.
Legal historians and labour economists are more useful than makeover television.
Read these voices as maps of a time and place — not as a fortune for Name changes.
