Introduction
Prenups in Australia are Binding Financial Agreements and they are powerful when done correctly. However many couples make simple mistakes that weaken the agreement and increase the risk of it being challenged in court.

The most common prenup mistakes in Australia
Mistake one leaving the prenup until the last minute
One of the most common errors is signing too close to the wedding or during a stressful life stage. Courts examine pressure and timing closely. When couples rush the process the agreement becomes vulnerable.
Avoid this by allowing genuine time for advice negotiation and disclosure.
Mistake two not receiving proper independent legal advice
Independent legal advice is mandatory in Australia. If either party did not receive proper advice or if advice certificates are missing the agreement may be invalid.
Mistakes include
• relying on verbal advice
• both partners using the same lawyer
• incomplete certificates
• unclear explanations of legal effect
Correct advice is essential.

Mistake three incomplete financial disclosure
Courts require full and frank disclosure. Prenups often fail because a party
• did not disclose superannuation
• forgot liabilities
• did not provide valuations
• omitted trust interests
• withheld business information
Disclosure must be accurate current and complete.
Mistake four using templates from overseas or the internet
Many people rely on online templates that are not designed for Australian law. These templates often use incorrect wording and fail to reference the Family Law Act.
If the document does not align with Australian requirements courts may set it aside.

Mistake five creating terms that cannot be enforced
Prenups cannot control everything. Couples often include terms that
• attempt to set parenting arrangements
• try to restrict future court access
• attempt to fix future child support
• impose unrealistic financial terms
Including unenforceable terms weakens the agreement.
Mistake six failing to update the prenup when life changes
Prenups can become outdated if circumstances change. Many couples never update their agreement even when
• new property is purchased
• a business grows
• a child is born
• an inheritance is received
• finances change significantly
A review or update may be necessary.

Mistake seven agreements that are significantly unfair at signing
Fairness is assessed at the time the agreement is made. If one party had far more bargaining power or did not understand the outcomes this may create risk.
Clear negotiation and proper advice help prevent this issue.

Mistake eight poor document storage or missing evidence
Courts expect
• the full signed agreement
• the advice certificates
• disclosure documents
• valuations
• clear communication records
If documents are missing the agreement may be harder to enforce.
Mistake nine relying on informal amendments
Any change to a prenup must follow the same requirements as the original agreement. Handwritten notes side letters or informal edits will not be valid.
How to avoid all prenup mistakes
To avoid risk ensure
1 both parties receive proper legal advice
2 disclosure is complete
3 there is time for negotiation
4 the drafting is correct
5 all documents are stored correctly
6 the agreement is updated when life changes
