What is a binding financial agreement?
A binding financial agreement (BFA) is a private contract under the Family Law Act about property or spouse maintenance. People use them before, during or after a relationship. They are not “just a prenup,” and they fail if the legal formalities are treated casually.
Private contract
Not made by a court on the day you sign
Advice each side
Independent legal advice is mandatory
Not a US prenup
Australian formality is its own system
Can be set aside
The Act lists circumstances — get advice
When people use them
- Before a marriage or de facto relationship (the classic “prenup”).
- During a relationship, if finances change.
- After separation, as a private alternative to consent orders.
A BFA can be useful when someone is bringing a family company, a farm, or an expected inheritance into a new relationship, or when a couple wants a private ending after separation. Usefulness is not the same as validity. A useful idea drafted on a foreign template is still a fragile document.
Formality is the point
Australian BFAs have a reputation for being technical because they are. The Act requires writing, independent advice about the effect of the agreement and the advantages and disadvantages, and lawyer certificates. Skipping a step to save a week is how people end up in a setting-aside fight worth more than the advice would have cost.
Disclosure still matters. An agreement signed in the dark about a hidden company or an undeclared super balance is a fragile thing. “We trust each other” is not a certificate. Each lawyer needs enough information to give real advice, not a ceremonial signature in a café.
BFA or consent orders?
| BFA | Consent orders | |
|---|---|---|
| Who makes it? | The parties, with lawyers | A court, on your joint request |
| Court scrutiny of fairness | No judicial “just and equitable” check at the time | The court must be satisfied |
| Typical use | Before/during a relationship; some separations | After separation, to end the property cause of action |
| Advice | Mandatory independent advice each side | Strongly wise; not the same statutory certificate regime |
Choosing the instrument is a legal design decision. This page will not choose it for you. Some endings belong in consent orders because a super fund, a titles office or a stamp-duty exemption works more cleanly with a court order. Some beginnings belong in a BFA because there is no court case yet.
Pressure, timing and safety
A BFA waved in front of someone three days before a wedding is a risk, not a romantic gesture. So is a “sign this tonight or the kids do not come home” conversation after separation. If you feel unsafe, read family violence and do not sign. Independent advice includes the right to hear “do not sign this.”
What a BFA cannot paper over
It cannot make an unsafe person safe. It cannot replace a parenting order. It cannot, by clever wording, become a substitute for disclosure. It cannot be “signed for both of us” by one solicitor. If any of those sentences appear in a sales pitch, leave the room.
Setting aside is a legal fight, not a mood
The Act lists circumstances in which a court may set a BFA aside. Those words have case law behind them. This page will not invent extra tests and will not quote section numbers you should verify on the current Act. If someone promises a BFA is “ironclad,” they are selling comfort. Ask what happens if a child is born, if a business collapses, or if disclosure was incomplete.

Questions people ask
What is a binding financial agreement?+
It is a written agreement under the Family Law Act that can deal with how property and financial resources are divided, and sometimes spouse maintenance. Each party must receive independent legal advice before signing, and lawyers must provide the required certificates. Informal “we agreed” notes are not BFAs.
Is a BFA the same as consent orders?+
No. Consent orders are made by a court. A BFA is a private agreement that, if valid, can oust the court’s power to make a property or maintenance order about those matters. Different formalities, different setting-aside tests, different use-cases.
Can a BFA be set aside?+
Yes, in circumstances set out in the Act — for example certain kinds of fraud, unconscionability, or a material change relating to the care of a child that would cause hardship. Validity is a legal question. Do not draft one from a foreign prenup template.
Do I need a lawyer for a prenup in Australia?+
If you want a BFA that can actually bind, each party needs independent legal advice. One lawyer cannot act for both people. That is a feature, not a nuisance.
