See changing your child’s first name within a year of birth to find out how to apply to change your child’s first name before they turn 1.

If your child was born or adopted in another Australian state or territory, you need to apply to the interstate registry office.

If your application is approved, we will send the official certificate you choose and you will need to change your child's name everywhere they are registered in the community.

Certificate options

If your child was born in Queensland, you will be able to choose either an updated birth certificate or a change of name certificate (or both). If they were born elsewhere, you may only get a change of name certificate.

The application fee includes 1 free certificate. Additional certificates attract an extra cost.

Change of name certificates only provide some birth information, the new name and any previous change of name registered in Queensland by us. They are not proof of birth details.

Documents you will need to provide

Queensland born or adopted child

You must provide:

  • certified proof of ID for both parents (read the rules below if you are a single parent or legal guardian)
  • evidence explaining the reason if your or your child’s current name is different to the name on their birth certificate, such as
    • marriage certificate
    • family deed poll document
    • change of name document.

Your application will not be approved if:

Detailed rules and requirements are outlined in our change of name and prohibited name policies.

If only one of the parents shown on your child’s birth certificate is applying, you will need additional evidence to support this.

Overseas born or adopted child

You must provide:

  • certified proof of ID for both parents (read the rules below if you are a single parent or legal guardian)
  • a copy of your child's birth certificate—if you can’t get one, we may accept another evidence of birth document (more about this below)
  • evidence explaining why if your or your child’s current name is different to the name on their birth certificate, such as
    • marriage certificate
    • family deed poll document
    • change of name document
  • a copy of your child’s Australian citizenship certificate if they are a citizen.

If you can’t provide your child’s birth certificate, we may accept one of these instead (however, you will also need to provide a statutory declaration explaining why the certificate isn’t available, and including your child’s name at birth, as well as their date and place of birth):

  • their Australian visa
  • a travel document
  • a passport issued by your child’s country of birth with a letter from the consulate confirming your child's details.

If original documents are not in English, you must have them translated into English by an accredited translator and provide a certified copy of the original document with the original translation.

You also need to provide evidence that your child currently lives and has lived in Queensland for the past 12 months, such as a letter. The letter should:

  • be dated and signed on letterhead from your child’s
    • day care
    • school
    • doctor
    • employer
  • state how long they have lived in Queensland
  • state how long the person or organisation has known your child.

Your application will not be approved if:

  • you have not been able to provide enough
    • documentation to establish your identity
    • evidence that your child normally lives in Queensland
  • the change of name appears to be for a fraudulent or other improper purpose
  • the name you’ve chosen is a prohibited name.

Detailed rules and requirements are outlined in our change of name and prohibited name policies.

Rules for changing your child’s names

To change your child’s names between 1 and 18, you must:

  • not have changed your child’s first name before or only before their first birthday
  • not have changed your child’s family name in the past 12 months
  • have consent from both parents on your child’s birth certificate
  • have your child consent to changing their name (if aged 12 to 17)
  • choose a new name that is not a prohibited name
  • give a detailed reason for your child’s name change.

Who can apply

If both parents are shown on a child’s birth certificate, both parents need to consent to changing their child’s name.

If you are a single parent, you can apply to change your child’s name if one of the following applies:

  • you are the child’s mother and there are no details for your child’s father on the birth certificate
  • you have Queensland Magistrates Court order, ordering a change of name
  • one parent is deceased—a death certificate is required.

A person with sole parental responsibility under a Family Court order can’t apply to change their child’s name, unless the order explicitly states that the person can change the child’s name to a specific new name.

If you are a legal guardian (i.e. you have been appointed under a law of a state or the Australian Government), you can apply to change the child’s name if you have both:

  • evidence of legal guardianship issued by a court
  • a Queensland Magistrates Court order.
