No Fault Divorce Australia: Contested vs Uncontested

Australia operates a strict no-fault divorce system. The court doesn't consider who cheated, who was abusive, or who caused the relationship to break down. The only question is: have you been separated for 12 months and 1 day? If yes, the court grants the divorce. Your spouse cannot block it simply because they don't want the marriage to end.

Here's what "contested" and "uncontested" actually mean in this system — and what to do if your spouse refuses to cooperate.

What No-Fault Means in Practice

Under the Family Law Act 1975, the sole ground for divorce is irretrievable breakdown of the marriage, proven by 12 months and 1 day of continuous separation. That's it. The court doesn't hear arguments about:

• Adultery or infidelity
• Domestic violence (though this affects property and custody — separate proceedings)
• Financial irresponsibility
• Who "wanted" the divorce

This means there's no legal mechanism for one spouse to "contest" the divorce on moral or emotional grounds. The divorce will be granted if the separation period is met and the paperwork is correct.

Uncontested Divorce (Joint Application)

When both parties agree, you file a joint application. This is the fastest and simplest path:

• Both spouses sign the application as co-applicants
• No service of documents required (filing together counts as mutual notice)
• No court hearing attendance required — even with children under 18
• Filing fee is typically split between both parties
• Processing time: approximately 4–6 weeks from filing to hearing, then 1 month and 1 day to final order

Joint applications are processed entirely on the papers — a Court Registrar reviews the file and grants the order without any appearance.

"Contested" Divorce (Sole Application)

In Australian family law, a divorce can only be contested on two narrow factual grounds:

1. The 12-month separation period hasn't been met — the respondent argues you reconciled or that the claimed separation date is wrong
2. The court lacks jurisdiction — neither party is an Australian citizen, domiciled, or ordinarily resident

A spouse cannot contest the divorce because they disagree with it, want to save the marriage, or are angry about the filing. If you've been separated for 12 months and the court has jurisdiction, the divorce will be granted regardless of the respondent's feelings.

What If Your Spouse Won't Sign?

If your spouse refuses to participate, you file a sole application. You proceed without their signature. The process changes in three ways:

1. You must serve the documents — a third party (not you) must deliver the sealed court papers to your spouse. They have 28 days (42 if overseas) to file a Response.
2. Your spouse can file a Response — but only on the narrow factual grounds above. Simply writing "I don't agree" isn't a valid legal objection.
3. You may need to attend the hearing — if there are children under 18, or if service issues arise.

If your spouse ignores the papers entirely and doesn't file a Response, the divorce proceeds in their absence. The court doesn't require their consent.

What If You Can't Find Your Spouse?

If your spouse has moved without leaving an address and you genuinely cannot locate them, you can apply for:

• Substituted service — serving via email, social media, or through a family member (requires court approval and evidence of your search efforts)
• Dispensation of service — waiving the service requirement entirely, so the divorce proceeds without any notification to your spouse

Both require an Application in a Proceeding (A$155 fee) plus a detailed affidavit showing what you've done to find them — searches of the electoral roll, social media, contact with their family, last known employers.

Property and Custody Are Separate

A critical distinction: property settlement, spousal maintenance, and parenting arrangements are entirely separate from the divorce itself. Your spouse can dispute asset division or custody without blocking the divorce. These are different proceedings, often running in parallel.

Once the divorce order becomes final, you have 12 months to file any property or financial claims with the court. Missing this deadline requires special court permission.
