In construction projects, one of the most common disputes arises when work progresses, but payment does not follow. When invoices remain unpaid, many contractors instinctively think:
“If I am not being paid, I will stop work.”
However, under the NSW Security of Payment Act, stopping work is not simply a matter of fairness. It is a legal step that must follow strict procedures. Acting too early or incorrectly can expose you to serious legal and financial consequences.
Stopping Work Is Not Automatically Allowed
A key misunderstanding is assuming that non payment alone justifies stopping work.
Under the NSW Security of Payment Act, your right to suspend work depends on whether you have correctly followed the statutory process.
If you stop work without meeting the legal requirements, you may:
- Breach your contract
- Be liable for project delays
- Lose your legal protection under the Act
Stopping work is not a reaction. It is a regulated legal action that must be carefully executed.
How the NSW Security of Payment Act Works
The Act establishes a structured process for recovering progress payments. It is not the same as issuing a standard invoice.
To rely on the NSW Security of Payment Act, you must follow a sequence of steps:
- Serve a valid Payment Claim that complies with the Act
- Ensure it is delivered to the correct party within the required timeframe
- Wait for a Payment Schedule from the respondent
- If no response or underpayment occurs, consider adjudication
- Only after specific conditions are met can suspension of work be considered
If any step is incorrect, you may:
- Invalidate your Payment Claim
- Lose access to adjudication
- Lose the right to lawfully stop work
The system is driven by precision in documentation and strict timing.
Three Common Mistakes Contractors Make
1. Assuming Completed Work Equals the Right to Stop Work
Even if you have completed work and not been paid, you cannot automatically suspend work.
Without following the NSW Security of Payment Act process, stopping work may still be treated as a breach of contract.
2. Using an Invalid Payment Claim
A valid Payment Claim must:
- Clearly state it is made under the NSW Security of Payment Act
- Specify the amount claimed
- Explain how the amount is calculated
- Be properly served in a verifiable way
If the format or content is incorrect, the claim may not be legally valid, even if the amount is genuinely owed.
3. Believing a Formal Contract Is Required
Many contractors assume the Act only applies where a formal written contract exists.
In reality, the NSW Security of Payment Act may still apply where:
- Agreements are made verbally
- Terms are confirmed through emails
- Work has commenced without a signed contract
The Act focuses on whether construction work or related services were provided, not on the formality of documentation.
Consequences of Stopping Work Incorrectly
Stopping work without meeting legal requirements can create more serious problems than the unpaid amount itself.
You may face claims that:
- You breached the contract
- You caused project delays
- You are liable for liquidated damages
- The principal incurred additional costs hiring replacement contractors
In some cases:
- Insurance may not cover resulting losses
- You may lose your right to recover the outstanding payment
- You could face counterclaims exceeding the unpaid amount
The Correct Approach: Follow the Process First
To protect your position under the NSW Security of Payment Act, contractors should:
- Confirm the work falls within the Act
- Review whether your Payment Claim is compliant
- Reissue or correct claims where necessary
- Track whether a valid Payment Schedule is received
- Take action within strict statutory timeframes
- Confirm legal entitlement before suspending work
This process requires careful coordination of legal requirements, documentation, and deadlines.
Practical Insight: SOPA Rewards Precision
The NSW Security of Payment Act is fundamentally a procedure driven system.
In practice, outcomes are often determined not by the quality of work, but by:
- Accuracy of documents
- Compliance with timeframes
- Proper execution of each legal step
Contractors who do not follow the process precisely often lose leverage, even when payment is clearly owed.
Conclusion: Stopping Work Is the Highest Risk Step
While it may feel justified to stop work when payment is withheld, doing so without legal protection can create significant exposure.
The safer approach is:
- Understand your rights under the NSW Security of Payment Act
- Ensure all procedural steps are correctly followed
- Confirm legal entitlement before taking action
