What is challenging or setting aside an agreement?
People may want to challenge or overturn a legal agreement they signed, often a Binding Financial Agreement (BFA), separation agreement, or postnup. These documents are binding under the Family Law Act 1975, but there are legal grounds for challenging them.
Under Section 90K (married) or 90UM (de facto) of the Family Law Act, courts may set aside a Binding Financial Agreement if one party didn't disclose key assets or income, the agreement was signed under duress, undue influence or fraud, the terms are grossly unfair or unconscionable, or circumstances have changed significantly such as children, illness, or hardship. "Set aside" is the correct legal term for when courts declare these agreements invalid.
Key benefits of challenging an unfair agreement
Challenging a financial agreement can protect your rights and ensure decisions reflect your current life. You might pursue this if you no longer believe the agreement is fair, you signed it without understanding or under pressure, your ex hid major assets or lied, your circumstances have changed due to illness, new child, or hardship, or you want the court to review the agreement before moving forward.
It's important to know that challenging a financial agreement can protect your rights when the original agreement was made unfairly or no longer suits your situation. Agreements aren't always final, and if they were signed improperly or life has changed significantly, you may have legal options.

Yes, Australian courts may set aside a prenup if it meets the legal grounds under the Family Law Act. Common reasons include lack of independent legal advice, fraud, duress, or unconscionable terms.

You'll usually need to apply to the Family Court and show valid legal grounds under Section 90K or 90UM of the Family Law Act. The process involves filing an application, providing evidence of why the agreement should be set aside, and attending court hearings. Our AI can explain the steps, or we can connect you with a lawyer who specialises in BFAs.
Legal grounds include fraud or misrepresentation about assets or circumstances, duress or undue pressure when signing, lack of independent legal advice as required by law, unconscionable or grossly unfair terms, failure to disclose significant assets or debts, and material changes in circumstances since signing. You can ask the AI for tailored information based on your case.
Yes, but only if serious legal issues exist like unfairness or misrepresentation. Courts can set aside separation agreements using similar principles as BFAs if they were made improperly or have become unconscionable. The agreement may be challenged if signed under pressure or without proper disclosure. A lawyer may be needed for formal steps.
Courts may refuse to enforce an agreement that's clearly unfair or lacking proper legal advice. When an agreement is set aside, the court makes new orders based on Family Law Act principles, considering contributions and needs rather than the original agreement terms. Our AI can help you understand what might qualify as unfair or incomplete.
