Pre-Nuptial & Post-Nuptial Agreements in Australia: Protect Your Assets and Future
Entering into a marriage or de facto relationship is one of life’s most exciting milestones. While couples hope for lifelong happiness, it is equally important to consider practical financial planning. A Pre-Nuptial Agreement or Post-Nuptial Agreement, legally known in Australia as a Binding Financial Agreement (BFA), provides certainty and financial protection if circumstances change in the future.
At Paramount Lawyers, we help individuals and couples create legally enforceable agreements that safeguard assets, reduce future disputes, and provide peace of mind. Whether you are planning to marry, already married, or in a de facto relationship, our experienced family lawyers can guide you through the legal process.
What is a Pre-Nuptial Agreement?
A Pre-Nuptial Agreement, commonly called a “prenup,” is a legally binding financial agreement entered into before marriage or before commencing a de facto relationship.
The agreement outlines how property, financial resources, debts, businesses, investments, inheritances, and other assets will be divided if the relationship ends.
Although Australian family law refers to these as Binding Financial Agreements, the purpose remains the same—to provide financial certainty and minimise conflict.
What is a Post-Nuptial Agreement?
A Post-Nuptial Agreement is similar to a prenup but is entered into after marriage or once a de facto relationship has begun.
Couples often choose a postnuptial agreement when:
- Their financial circumstances have changed
- They receive an inheritance
- One partner starts or purchases a business
- They acquire significant assets together
- They want financial certainty after marriage
- They wish to protect children’s future inheritance
A postnuptial agreement allows couples to update or clarify financial arrangements without waiting until separation.
Why Should You Consider a Financial Agreement?
Many people mistakenly believe these agreements are only for wealthy individuals. In reality, they benefit couples from all financial backgrounds.
Some key advantages include:
Protect Existing Assets
If you own property, investments, savings, or a business before marriage, a financial agreement helps protect those assets.
Protect Family Businesses
Business owners often use financial agreements to prevent family businesses from becoming involved in property settlement disputes.
Safeguard Future Inheritances
If you expect to receive an inheritance or family wealth, an agreement can help preserve those assets.
Reduce Legal Costs
Without a financial agreement, property disputes after separation can become lengthy and expensive. A properly prepared agreement often saves significant legal costs.
Minimise Stress
Clear financial arrangements reduce uncertainty and can make relationship breakdowns less emotionally challenging.
Are Pre-Nuptial and Post-Nuptial Agreements Legally Binding?
Yes—but only if strict legal requirements under the Family Law Act 1975 are met.
To be legally enforceable:
- The agreement must be in writing.
- Both parties must sign voluntarily.
- Each party must receive independent legal advice.
- Lawyers must provide certificates confirming legal advice.
- The agreement must comply with Australian family law requirements.
- There must be full and honest financial disclosure.
Failure to satisfy these legal requirements may result in the agreement being challenged or set aside by the Court.
This is why obtaining professional legal advice is essential.
What Can Be Included?
A Binding Financial Agreement can address many financial matters, including:
- Real estate and investment properties
- Savings and bank accounts
- Superannuation interests
- Business ownership
- Company shares
- Family trusts
- Vehicles
- Debts and liabilities
- Future inheritances
- Financial responsibilities during the relationship
- Property division upon separation
Every agreement is tailored to the couple’s unique circumstances.
Can a Court Overturn a Financial Agreement?
Although Binding Financial Agreements are designed to avoid litigation, courts can set them aside in limited circumstances.
Examples include:
- Fraud or dishonesty
- Failure to disclose financial information
- Undue influence or coercion
- Unconscionable conduct
- The agreement becoming impractical
- Significant changes affecting the welfare of children
Working with experienced family lawyers significantly reduces the risk of future legal challenges.
Who Should Consider a Pre-Nuptial Agreement?
A financial agreement may be appropriate if you:
- Own property before marriage
- Have significant savings or investments
- Operate a business
- Have children from a previous relationship
- Expect an inheritance
- Have international assets
- Wish to protect family wealth
- Want financial certainty before marriage
These agreements are increasingly common among professionals, entrepreneurs, business owners, and blended families.
Common Misconceptions
“A Prenup Means We Don’t Trust Each Other.”
This is one of the biggest myths.
A financial agreement is simply part of responsible financial planning—similar to preparing a Will or purchasing insurance. It provides clarity rather than signalling a lack of trust.
“Only Wealthy Couples Need One.”
Not true.
Anyone with property, savings, superannuation, businesses, or future inheritances may benefit from a financial agreement.
“They’re Easy to Prepare Online.”
Online templates rarely account for individual financial circumstances or Australian legal requirements.
Improperly prepared agreements may not be enforceable, leading to costly disputes later.

Frequently Asked Questions
How much does a pre-nuptial agreement cost?
The cost depends on the complexity of your financial circumstances, assets, and negotiations. Investing in quality legal advice now can prevent significantly higher legal expenses in the future.
Can we change the agreement later?
Yes. Financial agreements can be updated or replaced if both parties agree and the new agreement satisfies legal requirements.
Does a financial agreement cover child custody?
No. Parenting arrangements and child support are governed separately under Australian family law and cannot be permanently determined by a financial agreement.
Is a financial agreement valid for de facto couples?
Yes. Australian law allows eligible de facto couples to enter Binding Financial Agreements before, during, or after their relationship.
