What Is a Prenuptial Agreement?
A prenuptial agreement — formally known as a Binding Financial Agreement (BFA) — is a legal document that sets out how assets, liabilities, income and financial resources will be dealt with if a relationship breaks down.
Under Australian family law, a properly prepared prenup can:
- Protect assets acquired before the relationship
- Clarify how future assets or inheritances will be treated
- Reduce uncertainty and conflict if separation occurs
- Avoid costly and stressful property settlement disputes
- Provide financial clarity for both parties from the beginning
A prenup is not about expecting a relationship to fail. It is about responsible planning, honest discussions and protecting both parties’ financial positions.
Do Prenuptial Agreements Apply in Australia?
Yes. Prenuptial agreements are legally recognised in Australia under the Family Law Act 1975 (Cth). When correctly drafted and independently advised upon, a binding financial agreement can exclude the Family Court’s power to determine how property is divided if the relationship ends.
Because these agreements must meet strict legal requirements to be enforceable, it is critical to work with an experienced lawyer who understands both the technical legal framework and the practical realities of family law disputes.
When Should You Speak to a Prenup Lawyer?
It is best to seek advice from a prenup lawyer as early as possible — ideally well before a wedding or the commencement of a de facto relationship. However, financial agreements can also be made:
- Before marriage or cohabitation (prenup)
- During a relationship
- After separation
Our Sydney prenup lawyers regularly assist clients who:
- Own property, businesses or investments
- Expect future inheritances or family wealth
- Have children from a previous relationship
- Want certainty around financial contributions
- Are entering a relationship later in life
Early advice allows time for proper disclosure, negotiation and independent legal advice, which are essential for enforceability.
What Can Be Included in a Prenup?
A well-drafted prenuptial agreement can deal with a wide range of financial matters, including:
- Real estate and property interests
- Businesses, trusts and corporate structures
- Superannuation interests
- Debts and liabilities
- Financial contributions during the relationship
- How assets will be divided upon separation
