Apply to record a change of sex

If your birth was registered in NSW and you've undergone a sex affirmation procedure, you can apply to have your Registry record updated. You can do this by mail, or in person at a service centre.

To record a change of sex on your own Registry entry, you need to be aged 18 years or older.

To record a change of sex on a child's entry, you must be the parent(s) or guardian(s) of a child:

• whose birth is registered in NSW
• who has undergone a sex affirmation procedure.

• the PDF form – 'Application to record a change of sex (applicant)'
• your current personal and contact details
• your personal details as registered at birth
• 2 statutory declarations completed by 2 different medical practitioners and witnessed by an authorised witness
• 3 certified forms of your identification, including photo identification
• your payment.

1. Check the eligibility requirements.
2. Download and complete the Application to record a change of sex (applicant) – PDF.
3. Make sure you have all the required documentation.
4. Submit your application using the details on the form.

• Your new Birth Certificate will not be marked in any way to indicate your sex has been changed
• If you've changed your name since your birth was first registered, a notation stating that your birth was 'Previously registered in another name' will appear on the new certificate
• Access to your old Birth Certificate is restricted by legislation once the change of sex has been recorded
• Certificates are sent by the Registry of Births, Deaths and Marriages via registered post and cannot be collected at a service centre
• If you change your mind, or decide the certificate is no longer required, your application fee will not be refunded
• Documents provided as proof of identity may have their authenticity verified through the online national Document Verification Service (DVS).
