Separation and divorce are different things in Australia. Separation is when the relationship ends in practice. Divorce is a formal court order that legally ends a marriage. You can be separated without being divorced, and de facto couples do not get divorced at all.

Most people use "separation" and "divorce" interchangeably. They mean different things, they trigger different legal timelines, and confusing the two can create real problems — particularly around property settlement and financial claims.

This is a short article because the distinction is genuinely not complicated. But it's worth understanding clearly before you make any decisions.

What separation means legally

Separation is the point at which a marriage or de facto relationship effectively ends — when at least one party has decided the relationship is over and acted on that decision.

There is no form to file, no government office to notify, and no date that gets officially recorded when you separate. The separation date is established by evidence and behaviour: who moved out and when, when you stopped presenting as a couple, when you told people, when you stopped sharing finances.

The separation date matters more than most people realise. It sets the clock running on property settlement limitation periods, child support assessments, and — critically — the twelve-month period you must complete before applying for divorce.

What divorce means legally

In Australia, divorce is a formal legal order from the Federal Circuit and Family Court that ends the marriage. It does not end a de facto relationship — de facto couples have no equivalent proceeding.

To apply for divorce, you must:

Have been separated for at least twelve continuous months. The court needs to be satisfied the marriage has broken down irreparably, and the twelve-month separation is the evidence for that. You cannot apply the day you separate. You must wait.

Be an Australian citizen, ordinarily reside in Australia, or regard Australia as your permanent home. Non-residents can apply but the rules are more complex.

File an application — either sole or joint — with the Federal Circuit and Family Court. You can do this online through the Commonwealth Courts Portal. As of 2024, the filing fee is around $940 for most applicants, with a reduced fee for eligible concession card holders.

If there are children under 18, the court needs to be satisfied that proper arrangements have been made for them before granting the divorce.

The divorce order becomes final one month and one day after it is granted. You are not divorced the day the order is made.

The key distinction: divorce does not settle anything financial

This is the part that trips people up most.

Divorce ends the marriage. It does not divide property, it does not assess child support, and it does not determine parenting arrangements. You can be divorced and still have an unresolved property settlement. You can have a complete property and parenting agreement and still be legally married.

These are separate legal processes and they run on different timelines.

The most important consequence: once a divorce order is made, married couples have twelve months to apply to the Family Court for a property settlement. After that, the limitation period closes and you need the court's permission to bring a claim — which may or may not be granted.

If you and your ex have not formalised your property settlement before the divorce is finalised, start that process immediately. Don't let the divorce order sit there while property matters drift.

Can you be separated and still live together?

Yes. The law recognises that some couples cannot afford to maintain two households immediately, or separate their living arrangements for other practical reasons. "Separated under one roof" is a legally valid status, but it requires evidence to establish.

Evidence might include: separate bedrooms, no shared social activities as a couple, telling family and friends, changes to financial accounts, written communications that acknowledge the separation date, or a statutory declaration from someone who can attest to the circumstances.

This matters if your separation date is ever disputed — particularly for property settlement claims or the divorce application. If you're separated under one roof, document it.

The de facto timeline

De facto couples in most Australian states and territories have two years from the end of the relationship to apply for a property settlement. Unlike the married couple's situation, there's no divorce order to create a secondary deadline. The clock starts from the date of separation.

Two years is not as long as it sounds when you're managing kids, work, and every other practical consequence of separation. Know your deadline and don't let it pass informally.

The timeline in plain summary

Day of separation → Property settlement clock starts. Child support can be assessed. Parenting arrangements should be established (informally to start, formally in time).

12 months after separation → Eligible to apply for divorce (married couples only).

One month and one day after divorce order → Divorce is final. Married couples now have 12 months to formalise property settlement before the limitation period closes.

2 years after separation → De facto property settlement limitation period closes (most states and territories).

Get these dates written down somewhere. Then make sure nothing important falls past them without being formalised.

What you actually need to do

File for divorce when you're ready — it's a clean administrative step that formally closes the marriage and sets the property clock. Most people can do it themselves through the Commonwealth Courts Portal without a lawyer.

Treat property settlement as a separate, parallel process. Don't wait for the divorce to resolve the house, super, and assets. Start those conversations early and get them formalised in consent orders or a binding financial agreement.

Know your separation date. Write it down. If you think it might be disputed, document it.
