Divorce australia requires 12 months and 1 day of separation to prove irretrievable breakdown under the Family Law Act 1975 (Cth). Separation can occur while living under one roof if genuine separation is evidenced. Filing early risks adjournment or refusal. Property and maintenance claims generally must begin within 12 months after the divorce takes effect.
Key Legal Points
- No‑fault divorce requires 12 months’ separation to prove irretrievable breakdown
- Separation begins when the decision is made, communicated, and behaviour changes
- Under‑one‑roof separation is valid but needs detailed affidavit evidence
- Brief reconciliation under three months may not reset the 12‑month clock
- File after 12 months and 1 day; miscalculations cause delay and extra cost
- Divorce does not resolve parenting, property, or spousal maintenance issues
- Property and maintenance claims usually must start within 12 months post‑divorce
In divorce australia, the 12-month separation rule is the key eligibility test for ending a marriage. It means spouses must be separated for at least 12 months before the Court can grant a divorce. Separation is about the marriage breaking down irretrievably, not simply living apart.
Definition and Core Principles
Legal Framework
Under the Family Law Act 1975 (Cth), Australia has a no‑fault regime. The Court only asks whether the marriage has broken down irretrievably, proven by at least 12 months’ separation. Section 48 sets out this requirement and allows separation ‘under one roof’ if there is evidence of genuine separation.
What Separation Means
Separation means at least one spouse decided the relationship was over and communicated that decision, followed by a change in conduct consistent with living separate lives. Financial, social, and domestic arrangements should reflect that change.
- Intention: a decision to end the marriage
- Communication: the other spouse is told
- Behaviour: lives are conducted separately
- Duration: at least 12 continuous months
- Proof: affidavit evidence if required
Divorce Australia: Understanding the 12-month Separation Rule
Separation under One Roof
Couples can be separated while living in the same home. In such cases, the Court expects evidence of separate sleeping arrangements, reduced joint activities, separated finances, and communication of the separation to friends or family. Third‑party affidavits often help.
Short Reconciliations
Brief attempts to reconcile will not necessarily reset the clock. If you resume the relationship for under three months and it fails, the earlier period of separation can be added to the later period. Longer reconciliations normally require the 12 months to restart.
Divorce Australia: Eligibility and Evidence
Eligibility Checklist
To file for divorce you must show:
- 12 months and 1 day of separation immediately before filing
- Either spouse is an Australian citizen, ordinarily resident, or regards Australia as home
- Proper arrangements are in place for children under 18, or you have explained concerns
Proving Separation
Evidence can include separate bank accounts, changed utilities, Centrelink or Medicare updates, and statements from friends or relatives. For under‑one‑roof cases, each party usually files an affidavit detailing the separation circumstances.
Process / Steps
How to Apply Step‑by‑step
- Calculate the separation date and ensure 12 months and 1 day has elapsed
- Gather identification, marriage certificate, and any affidavits needed
- Create a Commonwealth Courts Portal account and complete the divorce application
- Pay the filing fee or apply for a reduced fee if eligible
- If filing a sole application, arrange service on your spouse in accordance with Court rules
- Attend the hearing if required, especially where there are children under 18 or affidavit issues
- Receive the divorce order electronically, which becomes final one month and one day later
Documents You May Need
Standard documents include your marriage certificate and identification. You may also need translations, affidavits for under‑one‑roof separation, or proof of citizenship or residence.
What Counts as Separation under One Roof
Practical Indicators
In real scenarios, we see separation evidenced by ending a sexual relationship, separate bedrooms, independent budgeting, and telling family the marriage has ended. Joint parenting can continue without undermining separation.
Common Patterns
Common patterns include staying in the home for children’s schooling or affordability. This often arises when parties need time to plan property settlement or secure rental accommodation.
Common Mistakes
What to Avoid
- Filing before 12 months and 1 day has elapsed
- No affidavit evidence for under‑one‑roof separation
- Inadequate service on your spouse for sole applications
- Assuming divorce resolves property, superannuation, or spousal maintenance
Real‑world Examples
We often see an application rejected because parties failed to explain separate sleeping arrangements or continued joint finances. Another pattern is missing the 12‑month cut‑off by days due to miscalculating an attempted reconciliation.
Deadlines, Limits, and Costs
Time Factors
There is no time limit to apply for divorce once the separation requirement is met. However, there is a strict deadline after divorce: property and spousal maintenance proceedings must be commenced within 12 months of the divorce order taking effect.
Financial Considerations
The Court filing fee changes periodically, and reduced fees may apply for concession card holders or hardship. Budget for process server costs, affidavit preparation, translations, and any legal fees if you engage a lawyer.
Consequences of Not Meeting the Rule
What Happens if You File Too Early
If the 12‑month separation rule is not met, the Court cannot grant a divorce. Your application may be adjourned or dismissed, causing delay and additional cost. You would need to refile after the time requirement is satisfied.
Compliance Requirements
Accuracy in dates and evidence is vital. Where children are under 18, the Court must be satisfied proper arrangements are in place, which can prompt questions at the hearing if information is sparse.
Separation and Parenting, Property, and Safety
Parenting and Property Are Separate
Divorce is a separate proceeding from parenting orders and property settlement. Many couples finalise parenting plans and property consent orders before filing for divorce, particularly to avoid the 12‑month post‑divorce property time limit.
Safety and Family Violence
If family violence is present, safety planning and protective orders take priority. Living under one roof while separated is sometimes unsafe, and urgent applications may be needed to protect children and parties.
Key Legal Authority
Statutory Source
The 12‑month separation requirement is contained in Family Law Act 1975 (Cth) section 48. It confirms no‑fault divorce, separation under one roof, and the need to satisfy the Court of irretrievable breakdown.
Court Practice
Affidavit evidence is commonly required for under‑one‑roof cases or where dates are unclear. The Court focuses on practical indicators rather than formality.
How to Resolve / Next Steps
Practical Guidance
Record the separation date in writing and tell trusted family or friends. Segregate finances where appropriate, keep evidence of changed living arrangements, and diarise the eligibility date to avoid premature filing.

Frequently Asked Questions
When does the 12-month separation period start for divorce?
It starts when one spouse decides the marriage is over, communicates that decision, and the couple acts consistently with separation. Record the date, tell trusted people, and change living and financial arrangements to align with the decision. The application can be filed after 12 months and 1 day.
Can we be separated under one roof and still meet the rule?
Yes. You must show genuine separation despite living together. Evidence often includes separate bedrooms, reduced shared activities, separate finances, and statements from friends or relatives. Both parties, and ideally a third party, should file affidavits explaining the arrangements.
What if we tried to reconcile during the 12 months?
A brief reconciliation under three months does not necessarily reset the clock. If separation resumes and the total time exceeds 12 months, you remain eligible. A longer reconciliation usually restarts the 12‑month period. Keep clear records of dates.
Does divorce finalise property settlement and parenting?
No. Divorce is separate from property settlement, superannuation splitting, spousal maintenance, and parenting arrangements. You must start property or maintenance proceedings within 12 months after the divorce order takes effect, unless the Court grants leave out of time.
What documents do I need to apply for divorce?
You will need identification, your marriage certificate, and any translations if necessary. For separation under one roof or complex circumstances, prepare affidavits. If filing a sole application, follow service rules and keep proof of service on your spouse.
What if the Court is not satisfied about separation?
The Court may adjourn for further evidence or dismiss the application. Strengthen your affidavits, provide third‑party statements, and collate objective documents showing separate finances, living arrangements, and social separation before refiling.
