The Difference Between Separation and Divorce
For couples considering a relationship breakdown, understanding the difference between separation and divorce is an important first step. These terms are often used interchangeably, but in Australian family law, they mean different things—and carry different legal and emotional implications.
In this blog, we’ll break down the key differences between separation and divorce, when each option might be relevant, and what to consider if you’re navigating this path.
When are you considered to be separated in Australia?
In Australia, there’s no formal legal process and you don’t need to file any documents with a court to be considered separated.
Separation happens when one or both partners decide to end the relationship and start living separately.
This can include:
- Physically moving into different homes, or
- Living under the same roof but no longer sharing life as a couple (this is known as separation under one roof)
Once you’re separated, that date becomes important for many legal processes—including starting the 12-month waiting period required before applying for a divorce.
While there’s no certificate for separation, it can be helpful to keep a written record of the date you separated, especially if there might be disagreement further down the track.
What Is Divorce?
A divorce is the legal end of a marriage. You must apply through the Federal Circuit and Family Court of Australia, and the Court needs to be satisfied that:
- You’ve been separated for at least 12 months
- There’s no reasonable chance of you and your spouse getting back together
In Australia, we have a “no-fault” divorce system, meaning the Court doesn’t take into consideration why the marriage ended—only that it has ended.
After your divorce is granted, it becomes final one month and one day later. This is the legal point at which your marriage officially ends.

Do I Need a Divorce to Sort Out Parenting or Property?
No, you don’t need to be divorced to sort out:
These can—and often should—be addressed as soon as possible after separation. In fact, waiting too long can make things harder down the track.
Importantly, you only have 12 months from the date your divorce becomes final to start court proceedings for a property settlement (unless you are provided leave from the Court).
So even if you’re not ready to divorce just yet, it’s wise to get early advice about your rights and options.
