Many couples considering a Binding Financial Agreement (BFA)–commonly known as a prenuptial agreement–wonder whether it has an expiration date.
The simple answer is no, a prenup does not automatically expire in Australia.
Once legally executed, it remains in effect unless both parties revoke it, replace it with a new agreement, or a court sets it aside due to legal or fairness concerns.
However, while a prenup does not have a fixed time limit, certain circumstances can affect its enforceability.
Significant life changes, improper execution, or unfair terms may lead to the agreement being challenged in court.
To ensure a prenup remains valid and legally binding, it is crucial to understand what can impact its enforceability, when it should be reviewed, and how to protect its legal standing.
This article answers the most important questions about prenuptial agreements in Australia, providing clear guidance on how they work and what can affect their longevity.
Do Prenuptial Agreements Expire in Australia?
A prenuptial agreement does not expire on its own. Unlike a lease or an insurance policy, it does not have a built-in end date.
Instead, it remains valid throughout the marriage and even after separation or divorce, provided that it meets all legal requirements.
That said, a prenup can become invalid or unenforceable under certain conditions.
For example, if it was not drafted correctly, if circumstances have changed significantly, or if a court finds it unfair, it may no longer be legally binding.
Here are key points to understand about the duration of prenuptial agreements in Australia:
- A prenup remains valid indefinitely unless revoked, replaced, or overturned by the court.
- Marriage does not make a prenup expire, and neither does the passage of time.
- A court can set aside a prenup if it finds the agreement was made under unfair conditions or has become unjust due to changes in circumstances.
To ensure that a prenuptial agreement continues to be legally enforceable, it is essential to review and update it when necessary.

What Factors Can Cause a Prenup to No Longer Be Enforceable?
Although prenups do not automatically expire, they can be declared invalid or unenforceable by the Family Court of Australia under specific circumstances.
Below are the main reasons why a prenup may no longer hold up in court:
1. Improper Execution or Unfair Conditions
For a prenup to be legally binding, both parties must:
- Sign the agreement voluntarily, without pressure or coercion.
- Receive independent legal advice before signing.
- Have a full understanding of the financial implications.
If a party was pressured into signing or did not receive proper legal advice, the court may set aside the agreement.
2. Significant Changes in Circumstances
Major life changes can impact the fairness of a prenup. These include:
- The birth of children, especially if financial needs change.
- One spouse becoming seriously ill or unable to work.
- A significant change in financial status, such as a large inheritance or bankruptcy.
If a court finds that the agreement has become unjust due to these changes, it may decide to invalidate the prenup.
3. Fraud or Misrepresentation
A prenup must be based on full financial disclosure. If one party hides assets or provides false information about their financial situation, the court may rule the agreement invalid.
4. Unfair or Unreasonable Terms
If the terms of the prenup are too one-sided, meaning they unfairly benefit one party while leaving the other at a disadvantage, the court may refuse to enforce it.
For example, if a prenup leaves one spouse with no financial support after a long marriage, it may be considered unfair.
5. Revocation or Replacement
If both parties agree, they can cancel or replace a prenup with a new Binding Financial Agreement. This is useful when financial or personal circumstances change significantly.
Should a Prenup Be Updated or Reviewed Regularly?
Yes, a prenup should be reviewed and updated when necessary to ensure it remains fair and legally enforceable.
While a prenup does not expire, failing to update it when circumstances change can lead to disputes or court challenges.
When Should You Review Your Prenup?
It is recommended to review a prenup:
- Every few years to ensure it still reflects your financial situation.
- After major life changes, such as having children, a career shift, or significant financial gain/loss.
- If one party becomes financially dependent on the other, as the agreement may need to be adjusted for fairness.
- Following legal changes, as updates in Australian family law could affect the enforceability of the agreement.
Regular reviews with a family lawyer can help keep a prenup legally sound and protect both parties’ interests.
How Can I Ensure My Prenup Stays Legally Binding?
To ensure a prenup remains valid and enforceable, both parties should take the following steps:
1. Get Proper Legal Advice
Each party must receive independent legal advice before signing. This means consulting separate family lawyers who can explain the legal consequences of the agreement.
This is a key requirement under the Family Law Act 1975.
2. Ensure Full and Honest Financial Disclosure
All assets, debts, and financial resources should be disclosed by both parties before signing. Hiding assets can lead to the agreement being overturned in court.
3. Avoid Unfair or Extreme Terms
A prenup should be fair to both parties. If one person is left with little to no financial security, the court may rule the agreement unfair and set it aside.
4. Review the Agreement When Circumstances Change
If significant life events occur, such as children being born, financial changes, or serious illness, updating the prenup can help keep it relevant and enforceable.
5. Consider a Postnuptial Agreement
If a prenup is outdated, both parties can sign a new Binding Financial Agreement after marriage, called a postnuptial agreement. This can replace the old agreement with updated terms.
