How to Change Your Name in NSW: Eligibility, Fees and the 3-Year Residency Rule

Changing a legal name in New South Wales is a direct application to the NSW Registry of Births, Deaths and Marriages, not a court process, and costs $203 for a standard application or $233 for priority processing, though an applicant not born in NSW must first meet an unusually long three year residency requirement that most other Australian states do not impose.

Who Can Apply

New South Wales handles adult name changes as a direct application to the NSW Registry of Births, Deaths and Marriages, administered under the Births, Deaths and Marriages Registration Act 1995 (NSW). This page deepens the national overview of changing your name in Australia with New South Wales specific detail.

According to NSW Government guidance, an adult born or adopted in NSW can apply directly to the Registry with no residency requirement. An adult who was born overseas, meaning not born in NSW, must instead have been a resident of NSW for three consecutive years immediately preceding the date of application. The same three year test applies where the parents of a child born overseas want to change the child's name in NSW.

This three year period is notably longer than the residency period most other Australian states and territories use for an equivalent overseas born applicant, which is commonly twelve months. NSW Government guidance does not state a separate visa or citizenship requirement beyond satisfying the residency test itself.

How Often You Can Change Your Name

NSW Government guidance states that a person can change their name only once in a 12-month period and no more than three times in a lifetime. Exceptions can apply where the applicant provides supporting evidence, such as a risk of domestic violence, that displaces the standard limit.

Changing a Child's Name

Both parents generally must consent to a change of a child's name, each completing their own part of the application, according to NSW Government guidance.

Where a child is old enough to have a view, NSW Government guidance describes a capacity test rather than a fixed consent age: the change cannot be registered unless the child consents, or the child is unable to understand the meaning and implications of the change. This differs from several other Australian states, which set a specific consent age, commonly 12. Neither NSW's published guidance nor the earliest available text of the relevant provision attaches a specific number of years to this test.

Where parents cannot agree on a child's name, NSW Government material describes a Registrar led resolution option in some birth registration circumstances. Whether that same mechanism, or a separate court application, is the operative route for an already registered child's name change specifically was not something confirmed from the sources available for this article, and a parent facing a genuine disagreement should confirm the current process directly with the Registry or seek legal advice.

Restricted and Registrable Persons

New South Wales applies two separate approval regimes on top of the standard application, according to NSW Government guidance.

A person in custody, on parole or subject to a supervision order is a restricted person under the Act and needs written approval from their supervising authority, such as Corrective Services NSW, before applying to change their name.

A person who is a registrable person, meaning someone on the Child Protection Register under the Child Protection (Offenders Registration) Act 2000 (NSW), must instead contact the Sex Crimes Squad of the NSW Police Force for permission before applying. This is a separate approving authority from the supervising authority approval that applies to restricted persons generally.

Names the Registrar Can Refuse

Under section 4(1) of the Act, the Registrar can refuse to register a name that is obscene or offensive, cannot practicably be established by repute or usage (for example because it is too long or made up of symbols without phonetic significance), resembles an official title or rank, or is contrary to the public interest for some other reason.

NSW Government guidance adds operational detail: each name component, meaning the surname or a given name, is limited to 50 characters including spaces, and numbers or symbols other than a hyphen or a phonetically or culturally significant apostrophe are not accepted. Names such as 1st, 7om, currency symbols and Roman numerals are given as examples of names the Registry rejects. Diacritical marks and accents cannot currently be registered, a systems limitation NSW Government guidance describes as current policy rather than a rule stated in the Act itself.

Fee

NSW Government guidance states that registering a change of name for an adult costs $203 for a standard application or $233 for priority processing, current as of 1 July 2026 (FY2026-27).

This registration fee is separate from the certificate. A certificate issued at the same time as registration costs an additional $70, which includes postage. Ordering a replacement change of name certificate later, as its own transaction, costs $70 for standard service or $105 for priority. Sending a copy of a certificate directly to a passport office costs $51.

How to Apply

According to NSW Government guidance, an applicant needs three valid identity documents, including at least one government issued photo identification. Applications can be lodged online through the Registry's own portal, on a paper form submitted at a Service NSW centre, or by post.

Processing takes up to five weeks for a standard online application, or three weeks for priority. A postal application, or one lodged in person at Service NSW, takes up to six weeks standard or four weeks priority.

What You Get

For an applicant born in NSW, a successful application updates the underlying birth registration itself. The applicant's birth certificate is reissued, and any previously issued birth certificates or change of name certificates are no longer valid. The applicant can choose whether the reissued certificate shows the new name with a note of the former name, or only a note that a change was registered.

For an applicant not born in NSW, there is no NSW birth record to amend, so the Registry instead issues a standalone change of name certificate.

After a Divorce

According to NSW Government guidance, reverting to a previous name after divorce does not always require a new registry application. If a married name was taken using only an Australian marriage certificate, meaning no formal change of name application was ever lodged, proof of divorce is generally enough to update identification back to the pre marriage name.

If the married name was instead taken through a formal change of name application, a new formal application, and its fee, are generally needed to revert. For the divorce process itself, see the Australia divorce guide.

Related Processes

New South Wales also runs a separate change of sex process, and since 1 July 2025 no longer requires a medical procedure before a change of sex can be registered. This is a distinct application from a change of name, though the two can be lodged using the same online reference number, according to NSW Government guidance.

Updating a passport or driver licence after a name change is handled by the relevant federal or state agency; the Australian Passport Office publishes its own requirements for updating a passport after a name change, and NSW BDM offers to forward a copy of a certificate directly to a passport office for a $51 fee.

Frequently Asked Questions

How much does it cost to change your name in NSW?

Registering the change costs $203 for a standard application or $233 for priority processing, according to NSW Government guidance current for FY2026-27. A certificate issued at the same time costs an additional $70.

How long do I need to have lived in NSW to change my name there?

If you were born in NSW, there is no residency requirement. If you were born elsewhere, NSW Government guidance requires three consecutive years of NSW residency immediately before applying, longer than the twelve months most other states require.

At what age can a child consent to their own name change in NSW?

NSW Government guidance does not set a fixed age. It applies a capacity test instead: the change cannot be registered unless the child consents, or the Registrar is satisfied the child cannot understand the meaning and implications of the change.

How many times can I change my name in NSW?

According to NSW Government guidance, once in a 12-month period and no more than three times in a lifetime, with exceptions available where supporting evidence, such as domestic violence risk, is provided.

Do I need approval to change my name in NSW if I have a criminal record?

It depends on your status. Someone in custody, on parole or subject to a supervision order needs written approval from their supervising authority. A registrable person under the Child Protection (Offenders Registration) Act 2000 (NSW) instead needs permission from the Sex Crimes Squad of the NSW Police Force.

Do I need to apply to change my name back after a divorce in NSW?

Not always. If you took your married name using only a marriage certificate, proof of divorce is generally enough. If you used a formal change of name application to take the married name, you generally need a new application and fee to revert.

What happens to my old certificates after I change my name in NSW?

If you were born in NSW, your birth certificate is reissued and any previously issued birth or change of name certificates are no longer valid. If you were not born in NSW, the Registry issues a standalone change of name certificate instead.
