If your relationship has ended, or you think it might be ending, it’s easy to assume separation and divorce are just two words for the same thing. They’re not, and knowing the difference matters for working out what to do next. This guide explains what each one actually means under Australian law, the 12-month rule that connects them, and how to work out whether you need a lawyer, mediation, or simply time. 

Quick Answer 

Separation is the factual end of your relationship: there’s no form to file and no court involved. Divorce is the formal legal process that ends a marriage, which you can only apply for once you’ve been separated for 12 months and one day. You can be separated without ever divorcing, and you’ll usually need separate advice for property or parenting matters, since divorce itself doesn’t resolve either. 

What Actually Counts as Separation? 

Separation happens the moment one or both of you decide the relationship is over and start living as separated, even if only one of you wants it. There’s no paperwork, no court, and no waiting period to “become” separated: it’s a factual state, not a legal one. That said, the date you separated matters later, particularly for the 12-month divorce rule and for property settlement time limits, so it’s worth noting it down clearly. 

Separating under the same roof 

You can be legally separated while still living in the same home, which is common for financial or family reasons. To show this, you’ll generally need evidence that the relationship itself has ended: separate finances, separate bedrooms, no longer presenting as a couple socially, or telling family and friends. If this is your situation, it’s worth getting advice early on how to document it properly. 

What Is Divorce, Legally Speaking? 

Divorce is the formal legal process that ends a marriage, granted by the Federal Circuit and Family Court of Australia. Australia has a no-fault system, so the only ground for divorce is that the marriage has broken down irretrievably: the court doesn’t consider who was at fault. The sole timing requirement is that you’ve been separated for at least 12 months and one day before applying, regardless of how long you were married. 

As of June 2025, the earlier rule requiring couples married less than two years to attend counselling or seek the court’s permission before applying has been removed, so this no longer affects when you can file. It’s worth remembering that a divorce order only ends the marriage itself: it doesn’t deal with property settlement or parenting arrangements, which are handled separately. 

Do You Need a Lawyer, or Is Mediation Enough? 

The divorce application itself is largely administrative, and many people file it through the Commonwealth Courts Portal without a lawyer. Where legal advice or mediation tends to matter more is everything around the divorce: dividing property, agreeing on parenting arrangements, or resolving disagreements you and your ex-partner can’t work through on your own. 

For most parenting matters, you’ll need to attempt family dispute resolution and obtain a certificate before applying to court, unless an exception applies, such as urgency or family violence. Reid Family Lawyers offers a complimentary, no-obligation initial 10-minute chat to help you work out which of these applies to you, and whether mediation, legal advice, or both make sense for your situation. 

Key Time Limits You Shouldn’t Miss 

• Divorce: You must be separated for 12 months and one day before applying; there’s no upper limit on how long you can wait. 

• Property settlement (married couples): applications generally need to be made within 12 months of your divorce order taking effect. 

• Property settlement (de facto couples): applications generally need to be made within 2 years of separation. 

• Missing these windows can mean needing the court’s special permission to proceed, so it’s worth getting advice well before a deadline is close. 

Which Situation Are You In? 

If you’ve just separated and things are amicable, mediation or family dispute resolution is often the right first step for sorting out parenting and property matters, well before divorce is even on the table. If there’s disagreement, complexity, or safety concerns, speaking with a family lawyer earlier can help you understand your options and protect your position. 

Our mediation and family dispute resolution pages go into more detail on how that process works if you’d like to explore it further. 

Making Your Next Move 

Separation and divorce are two different milestones, and you don’t have to tackle everything at once. Understanding which one you’re dealing with, and what it does and doesn’t resolve, makes it easier to know what to prioritise next.

FAQs 

Do I need to file anything to be legally ‘separated’ in Australia? 

No. Separation in Australia is a factual event, not a legal process, so there’s no form to file and no court involved. You simply need to be able to show, if it’s ever questioned, the date your relationship ended and that at least one of you communicated that to the other. 

How long do I have to wait to get divorced after separating? 

You need to be separated for at least 12 months and one day before you can apply for a divorce in Australia. Since June 2025, this is the only timing requirement: the length of the marriage itself no longer affects when you’re eligible to apply. 

Can I get divorced without a lawyer? 

Many people apply for divorce themselves through the Commonwealth Courts Portal without a lawyer, since it’s a largely administrative process. A lawyer becomes more valuable once property settlement or parenting arrangements are involved, particularly if you and your ex-partner don’t agree. 

Do I need mediation before applying for parenting orders? 

In most cases, yes: you generally need to attempt family dispute resolution and obtain a certificate before applying to court for parenting orders, unless an exception applies, such as urgency or family violence. A family dispute resolution practitioner can advise whether your situation qualifies for an exception. 

What happens if my ex and I still live together? 

You can still be considered separated while living under the same roof, but you’ll generally need supporting evidence, such as separate finances, separate sleeping arrangements, or informing family of the change. Courts assess this on the specific facts, so getting advice early can help.
