If you plan to end your marriage, you need to know what the law requires. In Australia, divorce follows a no‑fault system. That means the Court does not look at who caused the breakup.
You can only get a divorce in Australia if your marriage has broken down beyond repair and you have been separated for at least 12 months. You must also meet rules about citizenship or residency before you apply. The Court focuses on whether the relationship has ended for good, not on blame.
You also need to show that proper arrangements are in place for any children under 18. Divorce does not settle property, finances, or parenting orders, so you should understand how those issues fit into the wider process.
Key Takeaways
- Australia uses a no-fault system based on an irretrievable breakdown of marriage.
- You must be separated for at least 12 months and meet eligibility rules to apply.
- Divorce does not decide parenting or property matters, which follow separate steps.
No-Fault Divorce System and Core Legal Requirement
In Australia, you do not need to prove blame to end your marriage. The law focuses on whether your relationship has irretrievably broken down, not on who caused the separation.
Understanding Irretrievable Breakdown
Under the no-fault divorce system, the only ground for divorce in Australia is that your marriage has irretrievably broken down. This means there is no reasonable chance that you and your spouse will resume married life.
You prove this by showing that you have been separated for at least 12 months before you file your application. The Court does not ask for evidence of adultery, violence, or other misconduct. It only checks whether the required period of separation has passed.
You can still count the time if you lived in the same home during separation. This is known as “separation under one roof.” In that case, you must give extra details to show that the relationship had ended despite sharing an address.
If the Court accepts this evidence, it can grant a divorce order.
Role of the Family Law Act 1975
The rules for divorce in Australia come from the Family Law Act 1975. This law created the no-fault divorce system and removed the need to prove wrongdoing.
Section 48 of the Act sets out the single legal test: the marriage must have irretrievably broken down. The Act states that 12 months of separation is proof of that breakdown.
The Court does not deal with property division, parenting orders, or spousal maintenance as part of the divorce itself. A divorce order only ends the legal marriage.
Australian family law also sets timing rules. Once your divorce order becomes final, you usually have 12 months to apply for property or financial orders. If you miss this deadline, you must seek the Court’s permission to proceed.
Separation and Evidence Standards
To get a divorce in Australia, you must prove an irretrievable breakdown of your marriage. You do this by meeting strict separation requirements and giving clear evidence to the Court.
Separation Requirements and 12-Month Rule
Australian law recognises only one ground for divorce: irretrievable breakdown. You prove this by showing you and your spouse have lived separately and apart for at least 12 months before you file your application.
The Court counts the 12 months from the date of separation. Separation occurs when at least one of you decides to end the marriage and communicates that decision to the other.
You must also show there is no reasonable likelihood of reconciliation. If you resume your relationship for three months or more, the 12-month period usually resets.
If you reconcile for less than three months and then separate again, you may still count the earlier period. However, you must clearly explain the dates in your application and, if needed, at the divorce hearing.
Failing to meet the 12-month rule will delay your application. The Court cannot grant a divorce unless this time requirement is satisfied.
Separation Under One Roof
You can be separated even if you continue living in the same home. This is called separation under one roof.
In this situation, you must show that although you shared an address, your relationship ended. The Court looks at changes in daily life, not just physical distance.
You may need to show:
- You stopped sharing a bedroom
- You no longer socialised as a couple
- You separated your finances
- You told family or friends about the separation
You usually file an affidavit explaining these changes. If you apply alone, an independent adult who observed your situation may also need to provide evidence.
The Court examines these details closely. Living together does not prevent divorce, but you must prove genuine separation.
Evidence of Separation and Reconciliation Attempts
The Court requires clear evidence of separation before it grants a divorce order. Your application must state the exact date of separation and explain any periods of attempted reconciliation.
If you have children under 18, you may need to attend a divorce hearing. The Registrar may ask questions about your separation and living arrangements.
Useful proof of separation can include:
- Changes to bank accounts or bills
- Government agency updates
- Written communication confirming the separation
- Statements from friends or relatives
You do not need to prove fault. The Court does not consider why the marriage ended.
You only need to prove that the marriage broke down irretrievably and that you met the legal separation requirements for the full 12 months.
Eligibility and Application Process
You must meet clear legal rules before you apply for divorce in Australia. You also need to file the correct divorce application form and provide key documents through the proper court system.
Residency and Citizenship Criteria
You can only apply for divorce if you or your spouse have a strong link to Australia.
You must meet at least one of these rules:
- You were born in Australia.
- You are an Australian citizen by descent or by grant of citizenship.
- You live in Australia and see it as your permanent home.
- You have lived in Australia for at least 12 months before filing.
If you rely on citizenship by grant, you should provide your citizenship certificate.
If you have lived in Australia for 12 months, you may need to show proof such as passport records or visa details.
The Federal Circuit and Family Court of Australia will not grant a divorce unless one of these conditions applies. If neither you nor your spouse meet them, you cannot file a divorce application in Australia.
Marriage Certificate and Supporting Documents
You must provide a copy of your marriage certificate when you apply for a divorce.
If you married in Australia, you can use the official certificate from the Registry of Births, Deaths and Marriages. A ceremonial certificate often meets the requirement, but an official copy is safer.
If you married overseas, you must still provide your marriage certificate.
If it is not in English, you must:
- Have it translated by a qualified translator.
- File an affidavit from the translator.
- Attach both the original and the translated copy.
If you cannot get your certificate after reasonable efforts, you must file an affidavit that explains why.
You may also need extra documents if:
- You lived under one roof during separation.
- You changed your name.
- You cannot locate your spouse.
How to Apply for a Divorce
You must file your divorce application online through the Commonwealth Courts Portal.
The process involves these steps:
- Register for an account on the portal.
- Complete the online divorce application form.
- Upload your marriage certificate and any required affidavits.
- Pay the filing fee using a credit or debit card.
The Federal Circuit and Family Court of Australia handles all divorce applications in Australia.
You can prepare and file the application yourself, or you can ask a lawyer to do it for you. The court charges a standard filing fee, although you may qualify for a reduced fee if you hold certain concession cards or face financial hardship.
You must wait until you have been separated for at least 12 months and 1 day before you file.
Joint and Sole Applications
You can choose between a sole application and a joint application for divorce.
In a sole application, you apply on your own.
You are the applicant, and your spouse becomes the respondent.
You must:
- Sign the application yourself.
- Arrange for the documents to be formally served on your spouse.
Your spouse does not need to sign the form.
In a joint application for divorce, you and your spouse apply together.
You both review and sign the application before filing.
You do not need to serve documents on each other in a joint application. This option often reduces conflict and simplifies the process, especially when you both agree that the marriage has ended.
Arrangements Involving Children
If you have children under 18, the court will not finalise your divorce unless proper arrangements are in place. You must address where your children will live, how decisions will be made, and how you will support them financially.
Parenting Arrangements and Child Custody
Australian law no longer uses the term child custody in a formal sense. Instead, it focuses on parenting arrangements and parental responsibility under the Family Law Act 1975.
Parenting arrangements set out:
- where your children will live
- how much time they spend with each parent
- how you will make major long‑term decisions
You can record these arrangements in a parenting plan or apply to the Family Court of Australia or Federal Circuit and Family Court for parenting orders. Orders are legally binding. Parenting plans are not, but the court may consider them later.
The law encourages you to consult the other parent about major issues such as education, health, and religion. You must focus on what supports your child’s care, welfare, and development, not on what feels fair to each parent.
Court Considerations for Children of the Marriage
A court can only grant a divorce if it is satisfied that proper arrangements have been made for all children of the marriage under 18. This includes biological children, adopted children, and any child treated as part of the family.
The court looks at whether your children:
- have suitable housing
- receive financial support
- have access to education and health care
- maintain safe and meaningful relationships with both parents, where appropriate
The key legal test is the best interests of the child. The court considers factors such as safety, protection from harm, and the benefit of having both parents involved in their lives.
If arrangements appear inadequate, the court may delay the divorce or ask for more information before making the order.
Child Support and Parenting Matters
Parenting matters and child support are separate but connected issues. Even if you share care, one parent may still need to pay child support.
Services Australia usually assesses child support using a set formula. The formula considers:
- each parent’s income
- the number of children
- the amount of time each parent cares for them
You can also make a private child support agreement, either limited or binding. A binding agreement requires independent legal advice.
The court does not decide child support when granting a divorce. However, it must be satisfied that financial arrangements for your children are in place. Clear financial planning reduces conflict and supports your children’s stability after separation.
Financial and Legal Considerations Post-Divorce
After your divorce, you must deal with property, possible financial support, and strict legal time limits. You also need to understand when your divorce order becomes final and where to get reliable legal help.
Property Settlement and Spousal Maintenance
A divorce does not decide how you divide property or whether one spouse pays support. You must deal with property settlement and spousal maintenance separately.
Property settlement covers assets and debts. This can include:
- The family home
- Superannuation
- Savings and investments
- Vehicles
- Credit cards and loans
You can reach an agreement with your former spouse and formalise it through Consent Orders or a Binding Financial Agreement. If you cannot agree, you can apply to the Federal Circuit and Family Court of Australia for orders.
Spousal maintenance is financial support paid by one former spouse to the other. You may seek it if you cannot meet your reasonable living costs and your former spouse has the capacity to pay. The court looks at income, expenses, age, health, and care of children.
Timeframes and Divorce Order Finalisation
You must act within strict time limits after your divorce order becomes final. In most cases, a divorce order becomes final one month and one day after the court grants it.
Once the order is final, you have 12 months to apply to the court for property settlement or spousal maintenance. If you miss this deadline, you must ask the court for special permission to file out of time. The court may refuse your request.
You must not remarry until your divorce order is final.
An annulment is different from divorce. An annulment declares that a valid marriage never existed, but it applies only in limited legal situations. It does not replace property or parenting proceedings.
Legal Support and Community Services
You can manage some steps yourself, but many people seek advice from divorce lawyers to protect their financial position. A lawyer can explain your rights, draft agreements, and represent you in court if needed.
If you cannot afford private advice, you can contact community legal centres or Legal Aid in your state or territory. These services often provide free or low-cost help.
You can also call the Family Relationship Advice Line (1800 050 321) for information about family law services and referrals. Early legal advice helps you meet deadlines and avoid costly mistakes.
Frequently Asked Questions
In Australia, you can only get divorced if your marriage has broken down irretrievably and you have been separated for at least 12 months. You must also meet residency rules and address any arrangements for children under 18.
Does Australia have a no-fault divorce system, and what does that mean in practice?
Yes. Australia has a no-fault divorce system under the Family Law Act 1975.
This means the Court does not consider who caused the marriage to end. You do not need to prove blame, bad behaviour, or wrongdoing by either spouse.
The only legal ground for divorce is the irretrievable breakdown of the marriage. You prove this by showing that you and your spouse have been separated for at least 12 months.
What are the eligibility requirements to apply for a divorce in Australia?
You must show that your marriage has broken down irretrievably and that you have been separated for at least 12 months and one day before you file your application.
You or your spouse must also have a sufficient connection to Australia. You meet this requirement if you are an Australian citizen, live in Australia and see it as your permanent home, or have lived in Australia for at least 12 months before filing.
You must provide a copy of your marriage certificate. If it is not in English, you must file a certified translation.
What counts as 12 months and one day of separation for divorce purposes?
Separation starts when you or your spouse clearly communicate that the relationship has ended, and at least one of you acts on that decision.
You must then live separately and apart for 12 continuous months. You can reconcile for up to three months in total without restarting the 12-month period, but longer reconciliations will reset the clock.
You can only file your divorce application after 12 months and one day have passed.
Can you apply for divorce while living under the same roof, and what evidence is required?
Yes. You can be separated while living in the same home.
You must show that you stopped living together as a couple. This may include sleeping in separate rooms, dividing finances, cooking separately, or telling family and friends that you have separated.
The Court usually requires affidavit evidence from you and, in some cases, from an independent adult who can confirm the change in your relationship.
Do you need to prove adultery, cruelty, or family violence to get divorced in Australia?
No. You do not need to prove adultery, cruelty, family violence, or any other misconduct.
The Court does not examine the reasons for the breakdown of the marriage. It only looks at whether you have been separated for the required period.
Issues such as family violence may be relevant to parenting or property matters, but they are not grounds for divorce.
What additional requirements apply when there are children under 18 involved in a divorce application?
If you have children under 18, the Court must be satisfied that proper arrangements are in place for their care, welfare, and development.
You need to provide details about where the children live, how much time they spend with each parent, schooling, health, and financial support.
The Court does not require final parenting orders before granting a divorce. However, it may delay the divorce if it believes the arrangements for the children are not adequate.
