Legal change of name

Legally change your name

To change your name in the Northern Territory, you must be:

  • over 18 years old
  • one of the following:
    • born in the NT
    • born overseas and a resident of the NT for at least 12 consecutive months.

If you were born interstate, you must change your name in that state or territory.

If you were born overseas, you must submit the following with your application:

  • proof that you've been a NT resident for 12 consecutive months, such as:
    • bank statement with your name, current address and transactions within the NT
    • Power and Water bills with proof of payment, your name and current address
    • payslips from an employer in the NT showing your name and your employer's name or ABN number
  • certified copies of identity documents with your current name - if your name is not the same, you must provide a birth certificate and any previous change of name certificates
  • proof of citizenship or permanent residency status in Australia.

To change your name, follow these steps.

You must submit your application with the following, by mail or in person to a Births, Deaths and Marriages office:

  • proof of identity documents and evidence of any previous name changes eg. change of name, marriage or birth certificate
  • a detailed reason for changing your name - statements like ‘I want to’ or ‘personal’ are not detailed enough
  • a marriage certificate if you're changing your name after getting married
  • payment for the change of name fee - check the fee
