SECTION 01
What counts as separation?
Separation occurs when at least one partner decides that the relationship has ended and that intention is communicated or demonstrated through conduct. You do not need your partner’s consent, a lawyer, a court order or a registered separation certificate.
What matters is the combination of intention and actions. Telling your partner the relationship is over, changing household routines or separating finances may help establish the date of separation. Simply having an argument or sleeping in another room for a night does not necessarily establish separation.
SECTION 02
Can you separate while living together?
Yes. This is commonly called separation under one roof. Couples may continue to share a home for children, housing costs or practical reasons without continuing their relationship as partners.
Relevant evidence can include separate sleeping arrangements, changes in household duties and social activities, financial arrangements and communication to friends or family. No single change is conclusive; the overall circumstances matter.
Anna told Ben their relationship was over. She moved into a separate bedroom, they changed their financial and household arrangements, and they informed relatives. Their ongoing residence in the same home does not, by itself, prevent separation from being recognised.
If you were married and lived under the same roof during part of the 12 months immediately before a divorce application, the Court will generally require an affidavit explaining your circumstances and supporting evidence.
SECTION 03
Why the date matters
Record the date the relationship ended, including what was said, any changes in living arrangements and relevant messages or other records. The date can matter for divorce eligibility, government payments and financial proceedings.
Where partners disagree over the date, the Court may need to consider their evidence and conduct. A calendar note or text message can be helpful, but it is not automatically decisive.
SECTION 04
Separation and divorce
Separation and divorce are different. Separation is the ending of the relationship; divorce legally ends a marriage. A married couple generally needs to have been separated for at least 12 months and one day before applying for a divorce, with no reasonable likelihood of resuming married life.
Divorce does not itself decide who keeps the home, how assets are divided, whether maintenance is payable or what parenting arrangements apply. See our guide to divorce in Australia.
SECTION 05
Property and maintenance deadlines
The time limits are important, but they do not work the same way for married and de facto couples.
- Married couples: the usual deadline to start property or spouse-maintenance proceedings is 12 months after the divorce order takes effect — not 12 months after initial separation.
- Eligible de facto couples: the usual deadline to start property or de facto partner-maintenance proceedings is two years after the relationship breaks down.
Applications outside these periods may need the Court’s permission, and this is not guaranteed. You can discuss property settlement and make appropriate formal arrangements before divorce. Read about property settlement and financial application time limits.
SECTION 06
What about de facto couples?
De facto partners do not need a divorce order when their relationship ends. They may nonetheless have rights and obligations regarding property, maintenance and children.
The often-mentioned two-year rule is not a requirement that every de facto relationship last two years to exist. Rather, it is one of several possible eligibility gateways for certain financial orders, with exceptions such as a child of the relationship, registration or certain significant contributions. Explore de facto relationships and ending a de facto relationship.
SECTION 07
Children and practical arrangements
Parents can often make practical arrangements about where children live, time with each parent, schooling and decision-making without immediately going to Court. The child’s best interests and safety should guide decisions. Child support is a separate financial consideration, and you may need to notify Services Australia.
Separation is also a sensible time to review access to shared accounts, household bills, mortgages and insurance, and to keep records of important financial information. Seek individual advice before signing agreements or making large transfers.
SECTION 08
Do you need to notify anyone?
There is generally no Australian government register where you must formally register a separation. However, you may need to inform Services Australia of changes affecting Centrelink payments or child support, and consider whether your bank, insurer, employer or superannuation fund needs updated details.
If it is safe to do so, communicate the separation clearly to your former partner. If direct contact could put you at risk, seek appropriate safety and legal support instead.
SECTION 09
Your next steps
- Make a dated record of the separation and keep relevant communications.
- Identify urgent issues: safety, children, accommodation, income and access to money.
- Collect copies of important financial documents and consider temporary arrangements.
- Learn the different legal time limits for divorce and financial applications.
- Seek independent legal or financial advice where property, children or safety issues are complex.
There is no need to resolve everything immediately, but delaying until a legal deadline is near can narrow your options.
This is general information only, not legal advice. Family-law rules and requirements depend on individual circumstances. Western Australia has some different court arrangements, particularly for de facto financial matters.
