No Fault Divorce NZ: Why Your Spouse Cannot Block the Process
New Zealand Does Not Ask Why Your Marriage Ended
Under the Family Proceedings Act 1980, New Zealand operates a strict no-fault divorce system. The court does not hear allegations of adultery, cruelty, desertion, or any other marital misconduct. If your application contains fault-based claims, the court registry will strike them out.
For the standard track, the statutory ground for dissolution is that the marriage has broken down irreconcilably. It is established by showing that you and your spouse have been living apart for a continuous period of at least two years. A separate family-violence ground applies where a protected person has a final protection order against their spouse. Domicile and child-arrangement requirements still apply. No blame, no witnesses to bad behaviour, no airing of grievances.
What "No Fault" Means in Practice
The no-fault framework has several practical consequences that catch people off guard:
Your spouse cannot refuse to divorce you. If the statutory requirements are met, your spouse's lack of cooperation does not itself prevent the dissolution. They can choose not to sign a joint application, but that simply means you file a sole application (Pack 1) and have them served. Their silence after service does not prevent the divorce — it means the application proceeds undefended.
Past behaviour does not affect the dissolution. Even if one party's conduct caused the separation, it has no bearing on whether the statutory requirements for dissolution are met. The court applies those requirements rather than deciding blame.
Fault matters in other proceedings, not this one. While the standard dissolution ground is fault-free, other legal proceedings may consider conduct. Family violence is relevant to protection orders and parenting arrangements under the Care of Children Act 2004, and a final protection order can support the separate family-violence dissolution pathway. Financial misconduct can be relevant to relationship property claims under the Property (Relationships) Act 1976. These issues are separate from the standard dissolution application.
What a Respondent Can Contest
A respondent who receives a sole dissolution application can file a Notice of Defence (Form G12). The grounds for defence are extremely narrow, and the court decides whether the statutory requirements for dissolution are met:
- The two-year separation period has not been met — the respondent claims the parties were not actually living apart for two years, perhaps because they resumed cohabitation for more than three months total during the period
- The court lacks jurisdiction — neither party is domiciled in New Zealand
- The child arrangements are not satisfactory — where arrangements for dependent children under 16 are required, the court is not satisfied with them
Those are the main issues that can affect the order. "I don't want a divorce" is not a ground. "They cheated first" is not a ground. "The children need two parents under one roof" is not a ground, though child welfare arrangements must be satisfactory before the order is made.
Defended applications are referred to a Family Court judge for hearing, who determines whether the statutory requirements are met.

When Your Spouse Refuses to Sign
If your spouse will not cooperate with a joint application, the path forward is straightforward:
- File a sole application using Pack 1
- Have someone other than yourself personally serve the documents on your spouse
- File proof of service (Form G8, Affidavit of Service)
- Wait out the response window — 21 days if served in New Zealand
- If no defence is filed, the registrar or judge proceeds to make the dissolution order
Your spouse's refusal to engage adds some weeks to the timeline and the cost of a process server (NZ$80–$150), but it does not change the outcome. The two-year separation clock does not reset because one party is uncooperative.
If your spouse cannot be located at all, you can apply for substituted service (Form G21) — the court may allow service via email, social media, or through a relative.
The Reconciliation Exception
New Zealand's no-fault system includes one nuance that can restart the clock. If you and your spouse resumed living together during the two-year separation period, the law allows up to three months of cumulative reconciliation without breaking the separation. If the total time spent living together again exceeds three months, the two-year period resets entirely and you must start over.
This means a respondent could potentially contest the separation timeline by arguing that reconciliation attempts added up to more than three months. Accurate record-keeping of any time spent living together is essential.
Moving Forward Without Permission
The no-fault system exists because the law recognises that a marriage cannot be sustained by only one party's willingness. If you have been separated for two years and satisfy the other statutory requirements, the dissolution is a matter of administrative process, not negotiation.
