How to Apply for a Divorce in Australia: The Complete Guide

If you've reached the point of actually applying for divorce, you've probably already done the hardest part. The emotional decision is usually behind you by the time the paperwork starts. What's left is a process that is more administrative than most people expect, but one that still trips people up in small, avoidable ways: a missed date, an unclear answer about the kids, a marriage certificate nobody can find. This guide walks through how to apply for a divorce in Australia from start to finish, so you know what the court actually needs from you and roughly what to expect along the way.

A quick note before we start: this article explains the general legal process for divorce in Australia. It isn't personal legal advice, and it doesn't cover your property settlement, parenting arrangements, or superannuation, which are separate legal processes with their own rules and timeframes. If your situation is complicated, for example an overseas marriage, a spouse you can't locate, family violence, or a marriage certificate you can't obtain, it's worth getting advice specific to your circumstances before you file.

Australia has no-fault divorce, and that changes everything about the process

Australia has operated a no-fault divorce system since 1975. The Federal Circuit and Family Court of Australia (FCFCOA) does not ask why your marriage ended, who was “at fault,” or whether one of you behaved badly. The only thing the court needs to be satisfied of is that your marriage has broken down irretrievably, and the way you prove that is by showing you've been separated for the right length of time. There's no requirement to air the reasons for the split in your application, and the registrar assessing your paperwork isn't interested in them.

This matters practically, because it means your application form asks almost nothing about the breakdown of the relationship itself. It asks about dates, about children, about citizenship and residency, and about your marriage certificate. That's really the shape of the whole process.

Are you eligible to apply for a divorce in Australia?

Before you can apply, you need to meet a few threshold requirements.

You and your spouse need to have been separated for at least 12 months and one day before you file your application. This is the one non-negotiable timeframe in the whole process, and the court checks it closely. Under section 50 of the Family Law Act 1975, a single, brief reconciliation attempt of up to three months generally doesn't reset the clock; the periods of separation before and after can usually be added together.

Reconcile for longer than three months, or attempt reconciliation more than once, and the position becomes less straightforward, so it's worth getting advice if this describes your situation rather than assuming your original separation date still counts. It's also entirely possible to be separated while still living in the same home, known as being “separated under one roof.” The court will still grant a divorce in these circumstances, but you'll need to file additional evidence, typically affidavits from you and, ideally, an independent person such as a friend or family member, confirming that the relationship had genuinely ended even though you were sharing an address.

You also need a connection to Australia. At least one of you must be an Australian citizen, or regard Australia as home and intend to live here indefinitely, or have been ordinarily resident in Australia for the 12 months immediately before filing. This applies even if your marriage took place overseas.

Finally, you'll need your marriage certificate, or a certified translation and an accompanying affidavit if it isn't in English. If you can't locate it, the court has a process for this too, though it involves filing an affidavit explaining the circumstances of your marriage and why the certificate can't be produced.

How to apply for a divorce in Australia, step by step

Applications are made online through the Commonwealth Courts Portal, using the Application for Divorce eForm. Paper filing is only available in limited circumstances, so most people will do this entirely digitally.

The first real decision is whether to apply on your own (a sole application) or together with your spouse (a joint application). A joint application tends to be the more straightforward path where you and your spouse are on reasonably cooperative terms, since neither of you has to serve the other with documents, and you don't need to prove service to the court, which removes one of the more fiddly parts of the process. A sole application is the right option where communication has broken down, where there are safety concerns, or where your spouse isn't willing to cooperate. If you file alone, you'll be the applicant and your spouse will be the respondent, and you'll be responsible for formally serving them with the application later in the process.

Whichever path you take, your application will ask you to set out the details of your marriage and separation, your citizenship or residency basis for applying, and information about any children of the marriage under 18, including where they live, how they spend time with each parent, and their schooling, health, and financial support arrangements. This doesn't need to be exhaustive, but it does need to be honest and complete enough for the court to be satisfied that proper arrangements are in place, or to understand why they aren't yet settled. If the information you provide isn't sufficient, the registrar can adjourn your hearing and ask for more before the divorce is granted.

You'll upload your marriage certificate, or the certified translation and affidavit if applicable, as part of the filing. If you've changed your name, or there are relevant family violence or other court orders, those documents may also need to be included.

What it costs to apply for a divorce in Australia

The court charges a filing fee for a divorce application, set under the Family Law (Fees) Regulations 2022 and indexed each year on 1 July. As at 1 July 2026, the standard filing fee is $1,170, with a reduced fee of $390 available if you hold an eligible concession card, such as a health care card, pensioner concession card, or Commonwealth Seniors Health Card, or can demonstrate genuine financial hardship. For a joint application, both applicants need to independently qualify for the reduced fee for it to apply; if only one of you qualifies, the full fee is payable. Because these fees increase annually, it's worth checking the current figure on the Commonwealth Courts Portal at the time you file rather than relying on a number you've seen somewhere online, including this one.

Beyond the filing fee, what you spend depends entirely on whether you handle the application yourself or engage a lawyer, and whether property, superannuation, or parenting matters need to be resolved alongside the divorce itself. A divorce application on its own, with no dispute about the divorce order, is one of the more affordable pieces of family law process in Australia. Where the real cost tends to build is in property settlement, which is a separate and often more involved process.

If you're applying alone: serving the divorce application on your spouse

If you've filed a sole application, you're required to formally serve a sealed copy of the application on your spouse. You can't do this yourself in person; service has to be arranged by another adult, either by handing the documents to your spouse or by post, and the person who serves the documents needs to sign an affidavit confirming they did so. Service needs to happen at least 28 days before the hearing if your spouse is in Australia, or 42 days before the hearing if they're overseas, to give them proper notice and time to respond if they want to.

If you genuinely can't locate your spouse, or there's a real safety reason you can't serve them in the usual way, the court can make an order for substituted service, allowing you to serve them another way such as by email or through a family member, or in rare cases dispense with service altogether. These applications need their own supporting evidence, and you'll usually be required to attend a hearing to explain the circumstances.

What happens at the divorce hearing, and do you need to attend?

Divorce hearings in Australia are conducted electronically, before a registrar, and you won't need to attend a courtroom in person or engage a lawyer to appear for you. In most cases, you won't need to attend at all. Court attendance is only required if you've indicated in your application that you want to attend, if either party has objected to the matter being heard in their absence, or if your spouse has filed a Response to divorce opposing the application. It's also sensible to plan to attend if you need to explain something unusual in an affidavit, such as a period of separation under one roof or a short marriage.

If your divorce is granted, it doesn't take effect immediately. The order becomes final one month and one day after the hearing, and you can't remarry before that date. Once it's finalised, you'll be able to download your divorce order through the Commonwealth Courts Portal.

What a divorce actually does, and what it doesn't

It's worth being clear about the limits of a divorce order, because this is where a lot of confusion sets in. A divorce order ends your marriage. It does not, on its own, divide your property, determine spousal maintenance, or settle parenting arrangements. Those are separate legal processes, governed by different parts of the Family Law Act, and they run on their own timeframes. In fact, once your divorce becomes final, you generally have only 12 months to apply for property or maintenance orders before you need the court's permission to do so. If you haven't turned your mind to your property settlement yet, it's worth doing that in parallel with, or even before, your divorce application, rather than assuming the divorce will sort it out for you.

The mistakes that slow divorce applications down

Most of the delays we see in divorce applications come down to a handful of avoidable issues: an incomplete answer about children's living and care arrangements, a marriage certificate that doesn't match the details in the application, separation dates that are vague or inconsistent with other evidence, or sole applicants who haven't left enough time for service before their hearing date. None of these are complicated to avoid once you know they matter, which is really the point of getting your head around the process before you file rather than after a registrar sends your application back for more information.

Where to go from here

If you're not sure whether you're ready to file, or your situation involves something the standard process doesn't quite cover, such as a spouse overseas, a missing marriage certificate, family violence, or a very short marriage, it's worth getting advice specific to your circumstances before you lodge anything.
