Do You Have to Be Separated Before Divorce in Australia?

Yes. Under the Family Law Act 1975, you must be separated for at least 12 months and 1 day before you can file for divorce. There are no exceptions to this rule, no matter how clear-cut the breakdown is.

Australia operates a strict no-fault system. The court doesn't care why your marriage ended — only that it has ended, demonstrated by at least 12 months of living separate lives.

What Counts as "Separated"?

Separation is a combination of intent, communication, and action:

1. At least one person decides the marriage is over (intent)
2. That decision is communicated to the other spouse — verbally, in writing, or through actions (communication)
3. You begin living separate lives — financially, domestically, and socially (action)

You don't need a formal separation agreement or legal document to start the clock. The date one person communicates their intent to end the marriage is typically the separation date.

Can You Separate Under One Roof?

Yes. The law recognises that housing costs, mortgage commitments, and children's needs may require you to keep living at the same address. You can be legally separated while sharing a home — but you'll need to prove it with additional sworn affidavits showing:

• Separate sleeping arrangements
• Financial independence (split bills, separate accounts)
• Separate domestic routines (cooking, cleaning, laundry)
• Telling friends, family, and government agencies about the separation
• No longer socialising or presenting as a couple

The Reconciliation Rule

If you get back together during the 12-month period, here's how it works:

• Reconciliation of 3 months or less: The 12-month clock doesn't reset. You can count the time before and after the brief reconciliation as part of your continuous separation period.
• Reconciliation longer than 3 months: The clock resets completely. You need a fresh 12 months from the date you separate again.

This rule is designed to encourage genuine attempts at reconciliation without penalising couples who try briefly and realise the marriage is truly over.

What About Short Marriages?

Previously, couples married for less than two years had to attend marriage counselling or get a court exemption before filing. The government repealed this requirement in June 2025. Now all marriages — regardless of length — are treated identically. Twelve months of separation is the only prerequisite.

Can You Speed It Up?

No. There is no mechanism to shorten the 12-month period in Australian law. Unlike some countries with fault-based grounds that allow immediate filing, Australia's system requires the waiting period regardless of circumstances — even if:

• Both parties agree the marriage is over
• One party was unfaithful
• There was domestic violence
• The marriage was very short

The only way to "speed up" the overall timeline is to start counting your separation date correctly and file as soon as the 12 months plus 1 day have elapsed.

Filing One Day Too Early

If you file before the full 12 months and 1 day have passed, the court will reject your application. You'll lose time (not your filing fee — the portal validates the date before payment) but you'll need to wait and refile. Count carefully: if you separated on July 1, 2025, the earliest you can file is July 2, 2026.

What Happens After 12 Months?

Once the period has elapsed, you can file your divorce application through the Commonwealth Courts Portal. The standard filing fee is A$1,170 (A$390 with a concession card). From filing to final order typically takes 3-5 months depending on hearing availability and whether service needs to be arranged.

Planning Ahead

If you know your separation date is coming up on 12 months, start preparing now:

• Gather your marriage certificate
• Locate a Justice of the Peace for affidavit witnessing
• Decide whether you'll file jointly or as a sole applicant
• Document your separation evidence (especially if under one roof)
