Divorce and separation — the 12-month separation requirement and applying to the federal court

Australia has a no-fault divorce system that does not ask who was to blame. We walk you through it step by step: 12 months of separation as the sole requirement, the FCFCOA online application, property settlement and parenting as separate processes, and Child Support.

Australian divorce at a glance — no-fault and the 12-month separation

Divorce in Australia is a no-fault system under the Family Law Act 1975. The court does not consider whose fault the marriage breakdown was; the only ground for divorce is that the marriage has 'broken down irretrievably', proven by at least 12 months of separation. In other words, you do not need to prove fault such as infidelity or incompatibility — the fact of 12 months' separation is the requirement itself. If there was a temporary reconciliation of less than 3 months during the separation, the periods of separation before and after can be added together (the reconciliation period itself is excluded).

Key point: divorce and property settlement/parenting are separate processes

A divorce deals only with the legal ending of the marriage. Property settlement, spousal maintenance and parenting arrangements are all separate processes, handled independently at any time before or after the divorce. In particular, applications for property settlement and spousal maintenance must be made within 12 months of the divorce order becoming final — miss the deadline and you can only apply with the court's special permission. Remember: signing the divorce papers does not automatically sort out property matters.

The divorce application process — applying online via the FCFCOA

Divorce applications are made to the FCFCOA (Federal Circuit and Family Court of Australia) and are filed online through the Commonwealth Courts Portal. You can choose between a joint application filed by both spouses together and a sole application filed by one spouse alone — either way, the requirement is the same 12 months of separation.

Sole application vs joint application

A joint application is the simplest: no service on the other party is required, and you generally do not need to attend the hearing even if you have children. A sole application requires you to serve the documents on your spouse (at least 28 days before the hearing if they live in Australia, 42 days if overseas), and you must attend the hearing if there are children under 18. If you cannot expect your spouse's cooperation, simply proceed with a sole application.

  • If you apply for divorce less than 2 years after marrying, you must file a counselling certificate or obtain the court's permission
  • There is an application fee; health care card holders and people in financial hardship can apply for a reduced fee — the amount is adjusted each year, so check with the FCFCOA
  • Once granted at the hearing, the divorce order becomes final 1 month and 1 day later — you cannot remarry before it is final

If there are children under 18, the court must be satisfied that proper arrangements have been made for their care before granting the divorce. Describe the children's living, contact and support arrangements in detail in your application.

Eligibility and documents to prepare

To apply for a divorce, at least one spouse must meet one of the following: be an Australian citizen, live in Australia and regard it as home, or have ordinarily lived in Australia for at least 12 months immediately before applying. This means temporary visa holders without citizenship or permanent residency can also divorce in Australia if they meet the residence requirement, and the same applies to marriages that took place overseas.

  • Marriage certificate — if not in English, submit an English translation together with an affidavit from the translator
  • Evidence supporting the fact and start date of the separation — a lease at a separate address, Centrelink records, statements from people who know you, etc. (an affidavit is required for separation under one roof)
  • Proof of identity and residence — citizenship certificate, visa, passport, residence records and other evidence of the jurisdictional requirements

The separation start date is the reference point for the 12-month count and everything that follows. When you separate, communicating your intention in a dated form such as a text message or email can prevent disputes later.

Four application types by situation

Even for the same divorce, what you need to prepare differs depending on the application type and your situation. Find the type that matches your circumstances.

Joint application

Both spouses agree and apply together. There is no service process and attending the hearing is generally unnecessary, making it the simplest and fastest option. Both parties sign and file the application.

Sole application

One spouse applies without the other's consent or cooperation. Service of the documents is mandatory, and you must attend the hearing if there are children under 18.

Separation under one roof

Separation while living in the same home for financial or housing reasons can also be recognised. You must prove things like separate bedrooms, finances and household duties through affidavits from yourself and third parties.

Overseas marriage / temporary visa spouse

An overseas marriage can be dissolved in Australia if you meet the Australian residence requirements. However, the visa implications for temporary visa holders — such as partner visa applicants — are complex, so consulting an OMARA registered migration agent is essential.

Practical checklist when separating

Once you separate, there are many practical matters to sort out alongside the court process. Work through the following items in order.

  • Report the change in your relationship to Centrelink (within 14 days of the change) — you will move to the single rate and payments such as Family Tax Benefit will be recalculated
  • Sort out joint accounts and credit cards — check your ex-partner's withdrawal access and, if needed, open an account in your own name and change where your salary is paid
  • Sort out the lease and utility accounts — negotiate a lease transfer or termination with the landlord or agent, and separate the names on electricity, internet and other accounts
  • Review your will and superannuation beneficiary nominations — these do not change automatically on separation or divorce, so you need to update them yourself
  • If you have children, negotiate a parenting plan — use family dispute resolution (FDR) if needed, and convert it into consent orders if you need it to be legally binding

Warnings and common mistakes

The biggest losses come not from the process itself but from misunderstandings about time limits and legal effect. Avoid the mistakes below.

  • Missing the 12-month time limit after the divorce becomes final — applications for property settlement and spousal maintenance must in principle be made within 12 months of the divorce order becoming final; after that, you need the court's special permission
  • Believing a parenting plan is legally enforceable — a parenting plan is only a written agreement; if you need enforceability, you must obtain consent orders or parenting orders
  • Counting the 12 months without evidence of the separation start date — disputes over the start date will delay the process. A temporary reconciliation of less than 3 months can be added to the separation period, but that too needs to be documented
  • Setting a remarriage date before the divorce order is final — a divorce only becomes final 1 month and 1 day after the hearing, and you cannot remarry before then
  • As a temporary visa holder, failing to notify Home Affairs of the relationship change or deciding on your own — always consult an OMARA registered migration agent, and if there was family violence, check the family violence provisions section of our family violence support guide

Frequently Asked Questions

Can I get divorced even if my spouse doesn't agree?▾

Yes, you can. Australia has a no-fault divorce system, so you do not need your spouse's consent or proof of wrongdoing — you only need to show that you have been separated for at least 12 months, and you can file a sole application on your own. However, with a sole application you must serve the documents on your spouse, and if they avoid being served, you can apply to the court for alternatives such as substituted service.

Can we be recognised as separated while still living in the same house?▾

Yes — 'separation under one roof' can be recognised. Even if you live in the same home for financial or housing reasons, you must show evidence of separate bedrooms, separate household duties and finances, the end of the marital relationship, and having told others about the separation, through your own affidavit and affidavits from third parties such as family or friends. The documentation requirements are stricter than for an ordinary separation, so it is safer to check with Legal Aid or a similar service in advance.

Does a divorce automatically sort out property division and parenting as well?▾

No — this is the most common misunderstanding. A divorce deals only with the legal ending of the marriage; property settlement, spousal maintenance and parenting are all entirely separate processes. In particular, applications for property settlement and spousal maintenance have a time limit of 12 months from the date the divorce order becomes final — miss it and you can only apply with the court's special permission (leave).

I got married overseas — can I get divorced in Australia?▾

Yes, a marriage that took place overseas can be dissolved in Australia. You meet the jurisdictional requirements if either spouse is an Australian citizen, lives in Australia and regards it as home, or has ordinarily lived in Australia for at least 12 months immediately before applying. If your marriage certificate is not in English, you must submit an English translation together with an affidavit from the translator. Whether an Australian divorce is automatically recognised in your home country depends on that country's system, so check separately.

What happens to my visa if we separate or divorce while my partner visa is in progress?▾

For temporary visa holders — especially while a partner visa is being processed — a relationship breakdown is a complex issue that can directly affect your visa. You are required to notify Home Affairs of changes to your relationship, and what happens next varies greatly depending on your circumstances, so consulting an OMARA registered migration agent or an immigration lawyer is essential. If there was family violence during the relationship, your permanent residency application may still be able to proceed under the family violence provisions — see our family violence support guide as well.

How is Child Support decided?▾

Services Australia (Child Support) calculates it using a statutory formula. It takes into account both parents' incomes, the number and ages of the children, and each parent's care percentage, and you can apply for a child support assessment online. Parents can also agree privately and handle payments themselves (self-management or private collect), or have Services Australia collect the payments on their behalf (Child Support collect).

Can I apply on my own without a lawyer? How much does it cost?▾

Many people file the divorce application themselves without a lawyer via the Commonwealth Courts Portal, and the FCFCOA provides step-by-step guidance. The application fee is adjusted each year, so check the exact amount on the official FCFCOA website; health care card holders and people in financial hardship can apply for a reduced fee. However, if property or parenting disputes are involved, it is a good idea to get free advice from your state's Legal Aid first.

This guide is for general information only and is not legal advice. Fees, requirements and procedures change from time to time, so check the latest details on official sites such as FCFCOA and Services Australia. For decisions that depend on your personal circumstances, such as property settlement and parenting, always consult a family lawyer or Legal Aid (free legal advice — see our free legal help guide), and for visa implications, consult an OMARA registered migration agent. If you are at risk of family violence, call 000 in an emergency, contact 1800RESPECT (1800 737 732) for support, and read our family violence support guide first.
