Harmful Proceedings Orders in Australian Family Law: Meaning, Process, and Application Explained
When family disputes spill into the courts, the process should resolve conflict — not inflame it. Yet some litigants repeatedly file applications as a tactic: to intimidate, delay, exhaust resources, or maintain control. Australian law now gives the courts a sharper tool to stop that behaviour: the Harmful Proceedings Order.
In this guide, our Accredited Specialist Family Lawyer, Ian Field (Family Law, Wills & Estates), explains what a Harmful Proceedings Order is, when it applies, how to seek one, and what happens next — offering practical advice drawn from decades of experience.
What is a Harmful Proceedings Order?
A Harmful Proceedings Order (HPO) is a court order that prevents a person from starting new family law proceedings without first obtaining the court’s permission (called “leave”). It is designed to stop litigation abuse — repeated or strategic filings that cause harm to the other party or to a child.
- Jurisdiction & source of power: Federal Circuit and Family Court of Australia (and the Family Court of Western Australia in WA matters).
- Key provisions: Family Law Act 1975 (Cth), particularly ss 102QAC–102QAG (introduced by the Family Law Amendment Act 2023).
- What counts as “harm” (non-exhaustive): psychological harm or oppression, major mental distress, financial harm, and a detrimental effect on a parent’s capacity to care for a child (see s 102QAC(2)).
Think of an HPO as a front door lock. The door to the court isn’t bolted forever, but you must get the court’s leave before any new case can be filed. This filtering step is there to protect families from the damage of unnecessary or abusive litigation.

Why the Court Makes a Harmful Proceedings Order
The court won’t make an HPO lightly. It looks beyond the raw number of applications to the pattern and cumulative impact. Under s 102QAC(3), the court may consider:
- History and frequency of proceedings between the parties;
- Whether one party has repeatedly instituted or conducted proceedings (in any Australian court or tribunal);
- The cumulative effect (or potential cumulative effect) of harm to the other party or a child.
Importantly, the test focuses on impact, not just intent. The court asks: What has this litigation actually caused or is likely to cause? That includes emotional harm, financial pressure, and instability for children.
Typical red flags the court notices
- Re-litigating an issue already decided without a genuine change in circumstances;
- Contravention applications with little or no legal merit;
- “Urgent” applications timed to maximise disruption (e.g., holiday periods) without true urgency;
- Using proceedings to extend coercive control post-separation.
HPOs vs Vexatious Proceedings Orders (and Summary Decrees)
An HPO is not a blanket declaration that someone is a “vexatious litigant” across the board. It is targeted to family law and focuses on harm to the other party or children.
- HPO (ss 102QAC–102QAG FLA): Harm-focused; filters future filings via leave.
- Vexatious proceedings regime (Part XIB, other subdivisions): Addresses proceedings that are frivolous, vexatious, or an abuse of process.
- Summary decrees (s 102QAB): Allow early dismissal where there is no reasonable prospect of prosecuting/defending a case, or where a case is frivolous or an abuse of process.
These tools co-exist. The court chooses the proportionate response for the circumstances.
Real-World Illustrations (Recent Decisions)
Recent judgments show how courts apply the new provisions to prevent ongoing harm:
- F v M (2023): Multiple applications over two years to vary parenting orders without meaningful change in circumstances were found to be vexatious and harmful, including to the children’s welfare.
- Bruin & Bruin (No 4) (2024): The court emphasised that you don’t need to prove actual harm has occurred — it is enough to show reasonable grounds to believe future filings would cause harm.
- Lamport & Garside / Garside (2024): HPO made where further proceedings would likely cause severe psychological distress to parent and child; an out-of-time appeal lacking reasonable grounds was dismissed.
- Babic & Taccini (2024): Long litigation history; reasonable grounds that children would suffer psychological harm or major mental distress if the mother continued unwarranted filings. HPO granted.
These cases underline the child-centred lens and harm-prevention purpose behind HPOs.

Who Can Apply (and When the Court Acts on Its Own)
- A party to the proceedings (e.g., a parent or carer);
- A legal representative on the party’s behalf;
- An Independent Children’s Lawyer (ICL);
- The Court itself can act on its own initiative if the pattern is obvious.
Applications can be brought during live proceedings or after final orders where further filings are foreshadowed or have begun.
How to Apply for a Harmful Proceedings Order — Step by Step
- Identify the grounds
Map the conduct to s 102QAC(1)–(3): the history, frequency, and cumulative effect of harm to you or your child.
- Prepare your Application
File in the FCFCOA seeking a Harmful Proceedings Order under s 102QAC.
- File a comprehensive Affidavit (evidence is everything)
Include:- A chronology of all proceedings (dates, issues, outcomes);
- Judgments, orders, transcripts, or court comments indicating concerns;
- Medical/psychological evidence (GP/psychologist letters, counselling records) showing stress, anxiety, or impact on parenting capacity;
- Financial records evidencing cost burden;
- Prior cost orders or judicial warnings.
- A chronology of all proceedings (dates, issues, outcomes);
- Serve the documents
Provide the other party with proper notice, unless the court directs otherwise.
- Hearing & determination
The court assesses the pattern and harm. If satisfied, it issues the HPO as a final order (see s 102QAC(6)) and may also decide what notification (if any) is given to you in future if the other party later seeks leave (s 102QAC(7)–(8)).
Pro tip: Precision matters. A well-structured affidavit with exhibits, a readable chronology, and targeted legal submissions dramatically increases your prospects of success.

What an HPO Actually Does (and Doesn’t Do)
Once an HPO is made:
- The restrained party cannot file new proceedings without leave (permission) — s 102QAD.
- Any proceedings attempted in breach are stayed (put on hold) and can be dismissed with costs.
- The restrained party may apply for leave under s 102QAE, but only if they file an affidavit that:
- Lists all prior leave applications; and
- Discloses all relevant facts, favourable and unfavourable.
- Lists all prior leave applications; and
The court will grant leave only if the proposed proceedings are not frivolous, vexatious, or an abuse of process, and they have reasonable prospects of success (s 102QAG). The court may add conditions (e.g., security for costs).
It does not permanently bar someone from ever returning to court. Instead, it filters future litigation to prevent harm before it occurs.
Practical Impacts: Why HPOs Matter
Family litigation is expensive, exhausting and destabilising. When misused, it can:
- Drain finances through constant legal responses;
- Cause anxiety, insomnia and burnout;
- Undermine co-parenting stability and children’s wellbeing;
- Perpetuate coercive control through legal processes.
HPOs protect the integrity of the court process and the safety and wellbeing of families. They also free judicial resources for meritorious disputes.
Strategy Corner — For Applicants and Respondents
If you’re seeking an HPO
- Document everything: orders, applications, emails, hearing dates, costs, health impacts.
- Stay proportionate: ask for an HPO only where the pattern and harm are clear.
- Lead with evidence: medical letters, bills, timelines and prior judicial remarks are compelling.
If you’re facing an HPO application
- Engage early with specialist advice.
- Address the harm: demonstrate why further proceedings are necessary and how they won’t cause harm.
- If seeking leave later, ensure strict compliance with s 102QAE (full disclosure of facts and prior leave attempts).

FAQs (People Also Ask)
Can a Harmful Proceedings Order be revoked?
Yes. A party may apply to have an HPO revoked if there’s a genuine change in circumstances and reassurance that future filings will be responsible and non-harmful. The court will look for a sustained period without problematic litigation and evidence of compliance with orders.
Is an HPO the same as being declared a vexatious litigant?
No. An HPO is family-law specific and harm-focussed. Vexatious proceedings orders concern abuse of process more broadly. Different powers; different thresholds.
Does an HPO mean the other parent can never file again?
No. It means they must seek leave first. The court acts as a filter, allowing meritorious and necessary applications while blocking those likely to cause harm.
Can an HPO be made after only one or two applications?
Possibly. While patterns are common, a seriously disruptive or harmful filing might justify an HPO if the court is satisfied that further harm is likely.
How long does an HPO last?
There’s no fixed end date. It remains until varied or revoked by the court. The restrained party bears the onus to show that circumstances have changed.
What happens if someone tries to file despite an HPO?
The case can be stayed and dismissed, and the court may make adverse costs orders (s 102QAD(2)–(4)).
