Common Family Law Mistakes that Can Cost Thousands Of dollars

couple fighting

Most people do not realise they have made a mistake in family law until it is too late. 

The agreement has already been signed, assets have already been transferred, or positions have already been locked in. 

By that point, the financial impact can be significant. 

We are often asked questions like: 

“What if my ex is hiding assets during property settlement?” 
Or 
“How is property divided in divorce in NSW?” 

These questions usually arise when something does not feel right. 

In many cases, the issue is not just the situation itself. It is the decisions made early in the process. 

Understanding the most common mistakes can help you avoid unnecessary risk and protect your position from the outset. 

Mistake 1: Thinking Assets Can Be Hidden

One of the most serious mistakes we see is the assumption that assets can be concealed. 

This may involve: 

  • Delaying disclosure  
  • Moving funds  
  • Structuring income differently  
  • Minimising business income  
 

Under Australian family law, both parties are required to provide full and frank financial disclosure. 

 This obligation applies to: 

  • Income  
  • Assets  
  • Liabilities  
  • Superannuation  
  • Business interests  
  • Trusts and financial structures  

 

Following the 2024 and 2025 updates to the Family Law Act, there is continued emphasis on transparency and accountability. 

If assets are not disclosed: 

  • The court may draw adverse inferences  
  • Financial outcomes may be adjusted  
  • Orders can be set aside  
  • Costs consequences may apply  

 

Property settlement is based on the true asset pool, not what is disclosed selectively. Attempting to hide assets is not a strategy. It is a risk. 

For a more detailed breakdown of how these situations are assessed and what steps can be taken, see our article on what happens if assets are not properly disclosed during property settlement. 

Mistake 2: Not Understanding How Property Is Divided

Another common issue is misunderstanding how property settlement works. 

There is no automatic 50/50 rule. 

Instead, the court follows a structured process: 

  1. Identify and value the asset pool  
  1. Assess contributions of each party  
  1. Consider future needs  
  1. Determine whether the outcome is just and equitable  
 

This includes: 

  • Financial contributions  
  • Non-financial contributions  
  • Contributions as a parent or homemaker  
 

For clients with: 

  • Businesses  
  • Trusts  
  • Investment portfolios  
 

This process can become more complex. 

Without a clear understanding, people may agree to outcomes that do not reflect their true entitlement.

Mistake 3: Agreeing Too Quickly Without Advice

It is common for people to try to resolve matters quickly. 

Often to: 

  • Avoid conflict  
  • Reduce stress  
  • Move forward  
 

However, early agreements made without advice can create long-term issues. 

We often see: 

  • Incomplete financial understanding  
  • Informal arrangements  
  • Lack of documentation 
     

Once formalised, these agreements can be difficult to revisit. 

Taking time to understand your position is not delay. It is protection.

Mistake 4: Delaying Property Settlement

Delays are another common issue. 

Time limits apply: 

  • Married couples: 12 months from divorce  
  • De facto couples: 2 years from separation  
 

Delaying can: 

  • Limit your legal options  
  • Increase financial risk  
  • Complicate asset identification  
 

Early action provides clarity and structure.

Mistake 5: Letting Emotions Drive Financial Decisions

Separation is emotional. That is expected. 

However, decisions driven purely by emotion can lead to: 

  • Escalated disputes  
  • Poor financial outcomes  
  • Unnecessary litigation 
     

A structured approach allows decisions to be made with clarity and strategy. 

 

 Mistake 6: Not Formalising Agreements Properly

Many people reach agreement informally. 

However, without formalisation: 

  • Property matters remain open  
  • Financial exposure continues  
  • Agreements are not enforceable  
 

Formal options include: 

  • Consent orders  
  • Binding financial agreements


Finality with matters such as family law requires structure to be finalised.

 

A Matter We Recently Advised On

We recently advised a client who suspected that their former partner had not fully disclosed financial information. 

There were: 

  • Inconsistencies in income  
  • Delays in producing documents  
  • Unclear business structures  
 

Initially, the client was unsure whether their concerns were valid. 

They had also been presented with a proposed settlement. 

 We assisted by: 

  • Conducting a structured review of financial disclosure  
  • Requesting additional documentation  
  • Engaging financial expertise  
  • Clarifying the asset pool  
 

This process identified assets that had not been clearly disclosed. 

The matter was resolved through a structured agreement that reflected a more accurate financial position. 

The key issue was not the dispute itself. It was ensuring the process was followed properly. 

Why These Mistakes Happen

Most mistakes are not intentional. 

They happen because: 

  • People want to move on quickly  
  • The process feels overwhelming  
  • Advice is delayed
 

By the time advice is sought, the focus often shifts from planning to correcting.
