My Ex Won't Sign the Divorce Papers — Here's What Actually Happens

Can your ex actually block the divorce?

No. Under the Family Law Act 1975, the only ground for divorce is irretrievable breakdown of the marriage, established by at least 12 months of separation. There is no concept of fault and no mechanism for one spouse to veto a divorce the other spouse genuinely wants.

If your ex refuses to sign a joint application, you apply as a sole applicant instead. The court does not require your ex's agreement. Their signature is not needed.

What your ex can do is contest whether you have actually been separated for 12 months — but this is rare and difficult to sustain if you have lived apart, maintained separate finances, or told friends and family about the separation.

How divorce works in Australia

A divorce in Australia is granted by the Federal Circuit and Family Court of Australia once you have been separated for at least 12 months. The application is made through the Commonwealth Courts Portal. You can apply jointly with your spouse, or alone as a sole applicant.

Joint applications are slightly simpler to process, but sole applications are entirely routine — the Federal Circuit and Family Court of Australia grants thousands of sole-applicant divorces every year.

The filing fee as at 2026 is approximately $940 for a standard application, or $315 if you hold a concession card. See FCFCOA fee schedule for current rates.

Where children under 18 are involved, the court must be satisfied that proper arrangements have been made for their care. This is a threshold requirement — it is not a contested hearing about parenting, merely a procedural check.

Applying for divorce without your ex

A sole-applicant divorce follows the same legal process as a joint application, with one additional step: you must serve the divorce application on your spouse. This means they receive formal notice that the application has been made — they do not have to agree to it.

Service is typically done by a process server or registered post with acknowledgement. Once served, your ex has 28 days to respond. If they do not respond, the court proceeds with the application anyway. If they respond to dispute the separation period, a hearing is listed — but the bar for contesting successfully is high.

The divorce order is made at or after the hearing and takes effect one month later.

What they're really refusing

When a spouse says they "won't sign the divorce papers," they usually mean something else. They may be:

• Trying to delay the property settlement — a 12-month time limit to apply for property orders starts from the divorce date, and some spouses mistakenly believe refusing the divorce buys them time
• Using non-cooperation as leverage in negotiations about the family home, children, or financial support
• Genuinely distressed about the end of the marriage and not ready to formalise it
• Confused — some people believe agreeing to the divorce means agreeing to a particular financial split

Understanding which of these is actually happening is the key to resolving it — and often the right tool is mediation, not a court application.

Dan Toombs, AMDRAS Accredited Mediator and Lawyer: "I've sat with many people who've told me their ex 'won't cooperate'. In almost every case, what the other party is actually worried about is the financial outcome — not the divorce itself. Once we address that fear directly, the cooperation usually follows."

Property and parenting are separate from divorce

The divorce order dissolves the marriage. It does not resolve property, superannuation, parenting arrangements, or spousal maintenance. These are entirely separate legal processes under the Family Law Act 1975.

If your ex is resisting because they are worried about the financial consequences — mistakenly believing that signing locks in a financial outcome — that misunderstanding is worth addressing directly. Getting the divorce underway does not prejudge who gets what.

Property and parenting matters are where your ex's cooperation actually makes a practical difference. This is where property settlement mediation or parenting mediation can unlock a resolution.

What if your ex ignores the papers?

If your ex is served with a sole-applicant divorce application and simply ignores it — does not respond and does not appear at the hearing — the court will typically grant the divorce regardless. Non-response is treated as non-objection.

If you cannot locate your ex to serve them, there are provisions for substituted service (such as service through a known contact or electronically) or, in rare cases, dispensation from service. These require a family lawyer's assistance.

In all cases, the court's focus is on whether the marriage has irretrievably broken down — not on whether both parties have cooperated.

Worked example: Sophie's sole-applicant divorce

Sophie and Marcus separated in March 2024 after an eight-year marriage. They have two children aged 5 and 8. Marcus refused to discuss the divorce and told mutual friends he "would never sign."

Step by step:

1. September 2025: 12 months of separation reached. Sophie filed a sole-applicant divorce through the Commonwealth Courts Portal. Filing fee: $940.
2. October 2025: A process server served Marcus at his home address. Cost: approximately $200.
3. November 2025: Marcus did not respond. The matter was listed for an uncontested hearing. Sophie did not need to attend.
4. December 2025: Divorce order granted, taking effect January 2026.
5. Meanwhile: Sophie and Marcus attended mediation to resolve the property settlement. This was resolved by agreement in February 2026 and formalised as consent orders.

Marcus's refusal to "sign the papers" delayed nothing. The divorce proceeded on Sophie's timeline. The mediated property settlement cost each of them approximately $2,500 — compared to an estimated $30,000–$60,000 each for a contested property hearing.
