What separated parents in Queensland and Victoria need to know about name change laws.

One of the most emotionally charged questions that arises after separation is whether you change your child’s surname. Perhaps you want them to share your name after a difficult split, or you’re remarrying and want your child to feel part of a new family unit. Whatever your reasons, the short answer is you cannot unilaterally change your child’s surname without the other parent’s consent or a court order.

In both Queensland and Victoria, changing a child’s name is treated as a major parenting decision. Here’s what the law actually says and what your options are if your ex won’t agree.

Both Parents Must Consent

Under the Family Law Act 1975, both parents retain parental responsibility for their children after separation unless a court orders otherwise. This means decisions about major long-term issues, including a child’s name, must be made jointly.

When it comes to formally changing a child’s name, consent from both parents listed on the birth certificate is needed. This applies in both Queensland and Victoria.

In Queensland, the Registry of Births, Deaths and Marriages requires both parents to complete the application together. Similarly, in Victoria, Births, Deaths and Marriages Victoria states clearly that both parents on the birth certificate need to complete the application.

There are limited exceptions. A single parent can apply alone if they are the only parent named on the birth certificate, if the other parent is deceased, or if a court has specifically approved the name change.

Why the Law Requires Consent

A child’s surname is far more than an administrative detail. Courts recognise that names form a core part of a child’s identity and their connection to both sides of their family.

As noted by the Fitzroy Legal Service, a parent does not have the right to unilaterally change a child’s family name, even if they have primary care of the child. The requirement for consent protects the child’s relationship with both parents and prevents one parent from erasing the other’s connection to the child.

This principle was reinforced in recent amendments to the Family Law Act that took effect in May 2024. While the presumption of equal shared parental responsibility has been removed, parents are still expected to consult each other on major long-term issues affecting their children, provided it is safe to do so.

💔 It’s just a name some people say... But when it’s your child’s name, it means everything. So, can your ex legally really stop you from changing your child’s surname after separation? In Queensland and Victoria, you can’t just do it alone. You’ll need consent from both parents or a court order, and the court will only approve it if it’s in the child’s best interests. Sometimes it’s about safety. Sometimes it’s about identity. Every story is different. #FamilyLaw #QLDLaw #ParentingDisputes #FamilyCourtQLD

What If the Other Parent Won’t Agree?

When parents cannot reach an agreement, there are two main pathways. Either seeking a court order from the Magistrates Court for name change approval or applying to the Federal Circuit and Family Court of Australia for parenting orders that address the name change.

Before going to court, you will need to attempt family dispute resolution. The court requires evidence that you have made a genuine effort to resolve the matter outside the court system. Exceptions apply in cases involving family violence, child abuse or urgent circumstances.

In Queensland, if the sole issue is the child’s name change, a parent can apply to the Magistrates Court for approval. The Magistrate can approve the application if satisfied that the change is in the child’s best interests.

In Victoria, the County Court can issue a name change order where parents disagree. It is important to note that an order for sole parental responsibility does not automatically give a parent the right to change their child’s name. The consent requirement still applies unless a court specifically orders otherwise.

What Courts Consider When Deciding Name Changes

Courts do not approve name changes lightly. The guiding principle is always the best interests of the child, not the preferences or convenience of either parent.

The landmark case of Chapman v Palmer (1978) established the factors courts consider when determining whether a name change should occur. 

These remain the leading authorities in this area and include: 

• The welfare of the child is the paramount consideration
• The short and long-term effects of any change in the child’s surname 
• Any embarrassment likely to be experienced by the child if their name differs from the parent they live with
• Any confusion of identity that may arise if the name is or is not changed
• The effect a name change may have on the relationship between the child and the other parent
• The effect of frequent or random name changes.

The case of Beach v Semmler (1979) added further considerations, including the advantages in both short and long-term of the proposed change, the contact the other parent has had and is likely to have with the child and the degree of identification the child has with each parent.

More recent cases have confirmed that these principles still apply. In Waller v Casson (2015), the court rejected a mother’s application to add her surname to her eight-year-old son’s name, finding she had failed to provide evidence that the change would be in the child’s best interests rather than simply reflecting her own preference.

When Courts May Approve a Name Change

Courts are more likely to approve a name change in circumstances such as protecting the child from harm. Courts may also approve changes where the child’s established identity warrants it, for example, if the child has been known by a different name for most of their life and changing back would cause confusion.

Approval may also occur when the child strongly identifies with the proposed name, particularly for older children whose views carry significant weight. Some courts have ordered hyphenated surnames as a compromise that reflects both parents, allowing the child to maintain identification with both sides of their family.

When Courts Are Unlikely to Approve

Courts consistently reject applications based on a parent’s personal preference rather than the child’s welfare. In Chapman v Palmer, the Full Court noted that some parents treat their child’s surname more like a proprietary interest rather than what’s best for their child. 

The case of Flanagan v Handcock (2001) held that the child’s best interests must be carefully considered, but they are not necessarily decisive in every case. Courts will balance all factors and may decline a name change even where there is some benefit to the child if other considerations outweigh it.

Children Over 12 Have a Say

In both Queensland and Victoria, if your child is 12 years or older, they normally must consent to the name change. This reflects the recognition that older children have formed their own identity and should have a voice in decisions affecting them.

Courts will also consider the views of younger children where appropriate, though the weight given to a child’s wishes depends on their age and maturity. In some cases, courts have found that a child’s expressed preference was influenced by one parent and should not be given significant weight.

Recent Legislative Changes

The Family Law Amendment Act 2023, which took effect on 6 May 2024, introduced significant changes to how courts approach parenting matters.

While the presumption of equal shared parental responsibility has been removed, this does not mean parents can now make major decisions unilaterally. Parents are still encouraged to consult each other on major long-term issues, where safe to do so, and courts can still order joint or sole decision-making arrangements.

From 1 December 2024, amendments in some states allow a parent to change their child’s name if they have sole parental responsibility under a final parenting order for major long-term issues or specifically for the child’s name. However, obtaining such an order remains difficult without strong grounds.

Move Forward With Expertise 

Changing your child’s surname after separation is not something you can do on your own. The law recognises that a child’s name is central to their identity and their relationship with both parents.

If you want to change your child’s name and the other parent agrees, the process is straightforward through your state’s Registry of Births, Deaths and Marriages. If they do not agree, you will need to attempt mediation first and potentially seek a court order.

Courts will only approve a name change where there is clear evidence it serves the child’s best interests. Personal preferences, convenience or a desire for a fresh start are unlikely to be sufficient. Strong grounds such as protecting the child from harm or reflecting their established identity are more likely to succeed.
