Changing Your Name Explained
Many people go by a name that’s different from the one on their birth certificate. Sometimes it’s a small change, like altering the spelling of a first or last name, or adding a hyphen for a double-barrelled surname. Other times, it’s as simple as using a nickname that has become the norm.
While you can technically change your name whenever you like without any formal steps, it can cause problems when you need to prove your identity. If your ID is based on your birth certificate, driver’s license, or passport, you’ll need official documentation to show you’re the same person, but with a different name.
