Settlements play a central role in Australia’s litigation and dispute resolution landscape. They provide certainty, minimise legal costs, and help parties avoid the stress and unpredictability of a court hearing. As a rule, once a legal matter has been settled and formalised, both parties are expected to uphold the agreement and move forward. But what happens when circumstances change or when one party believes the settlement was unfair, improper, or incomplete? Can you reopen a case after a settlement in Australia?
While settlements are designed to bring finality, there are limited situations in which a court may allow a matter to be revisited. Understanding these exceptions can help both individuals and businesses better manage risk and protect their legal rights.
Are Settlements Final?
In most cases, yes. Settlement agreements—whether reached privately, through mediation, or formalised in court—are binding contracts. When parties sign a settlement deed or the court issues consent orders, the dispute is legally concluded.
Courts place strong emphasis on the finality of settlements because they encourage efficiency within the justice system and reduce unnecessary litigation. Reopening a matter undermines this finality, which is why Australian courts are generally cautious when asked to revisit closed cases.
When Can a Settlement Be Reopened?
Although rare, there are several recognised circumstances in which a settlement may be challenged or set aside.
Fraud, Misrepresentation, or Concealment
If one party intentionally withheld crucial information or misled the other during negotiations, the settlement may be invalid. For example:
- Concealing financial assets
- Providing false documents
- Misrepresenting key facts
Australian courts can set aside a settlement if it was obtained through deceit, as this undermines the integrity of the dispute resolution process.
Duress, Undue Influence, or Unconscionable Conduct
A settlement must be entered voluntarily. If a party was pressured, coerced, or exploited during negotiations, the agreement may be challenged. Factors such as:
- Imbalance of bargaining power
- Psychological pressure
- Threats or improper conduct
These may prompt the court to intervene, particularly in consumer, employment, or family matters.
Mistake
A settlement may be reopened if both parties were mistaken about a fundamental aspect of the agreement. This could include errors regarding:
- Essential facts
- Legal entitlements
- Interpretation of terms
However, mistakes must be significant. Minor misunderstandings rarely justify reopening a settlement.
Lack of Capacity or Legal Authority
If one party lacked legal capacity (e.g., due to mental impairment) or an authorised representative exceeded their authority, the settlement may be invalid.
Breach of Settlement Terms
Although a breach does not necessarily reopen the original dispute, it may lead to:
- Enforcement proceedings
- The court setting aside the agreement and reinstating the claim
If a settlement collapses due to non-compliance, the aggrieved party may be entitled to seek further remedies.
Public Policy Considerations
In exceptional cases, courts may intervene if a settlement violates public policy—such as attempting to undermine statutory rights or obligations.
What About Consent Orders?
Consent orders, particularly in family law, are more difficult to undo than private agreements. The Family Court may set aside consent orders only in strict circumstances, such as:
- Miscarriage of justice
- Significant change in circumstances
- Fraudulent evidence
Parties seeking to vary or revoke consent orders require strong legal grounds.
Reopening a Civil or Commercial Matter
Civil and commercial settlements are generally treated as contractual agreements. To reopen a case, a party will usually need to pursue:
- A court application to set aside the settlement deed
- Enforcement or rectification proceedings
The test applied by Australian courts is stringent, and the burden of proof lies with the applicant.
Steps to Take If You Want to Revisit a Settlement
- Seek immediate legal advice. Time limits may apply.
- Gather evidence of misconduct, mistake, or breach.
- Consider alternative dispute resolution before returning to court.
- Prepare for the possibility of costs. Unsuccessful applications may result in costs orders.
How to Avoid Problems With Settlements
To minimise future disputes:
- Ensure all terms are clear and in writing
- Obtain independent legal advice
- Avoid signing under pressure
- Confirm full disclosure of information
A properly drafted settlement deed significantly reduces the risk of future litigation.

While settlements are intended to resolve disputes conclusively, Australian law recognises that not all agreements are reached fairly. Whether due to fraud, pressure, mistake, or breach, there are circumstances in which reopening a case may be justified. However, these situations are the exception, not the rule.
Anyone considering challenging a settlement should seek timely, expert legal advice to ensure their rights and interests are protected.
