What is the Security of Payments Act?
The Security of Payments Act (SOPA) is legislation enacted across various states and territories in Australia to ensure that individuals and businesses in the building and construction industry receive timely payment for the services they provide. This Act is particularly crucial for subcontractors, as it provides a legal safeguard that helps to mitigate the risks associated with payment delays and disputes.
Purpose and Scope of the Security of Payments Act
Purpose
The primary purpose of the Security of Payments Act is to ensure that individuals and businesses involved in the building and construction industry receive timely and appropriate payment for their services. This legislation aims to address the common issue of delayed payments within the industry, which can significantly impact the cash flow and overall financial stability of subcontractors and other construction-related businesses.
By providing a legal framework that mandates prompt payment practices, the Act helps maintain the economic integrity and sustainability of the construction sector. It also aims to reduce the incidence of disputes related to payments, thus fostering a more cooperative and productive working environment across projects.
Scope
The scope of the Security of Payments Act encompasses all construction work across Australia, including but not limited to:
Building and construction services: This includes construction, alteration, repair, restoration, maintenance, extension, demolition, and dismantling of buildings or structures, whether permanent or not.
Related goods and services: The Act covers the supply or hire of goods, such as scaffolding, tools, and machinery, directly used on the construction site. It also includes services like architectural, design, and engineering services that are part of the construction process.
Engineering projects: This includes the construction, alteration, or repair of civil engineering works like roads, bridges, water supply, sewers, and other infrastructure.
The Security of Payments Act is implemented through state-specific legislation, which means while the overarching goal remains consistent, the exact rules and procedures can vary. Each Australian state and territory has enacted its version of the Act, tailored to address the unique aspects of its local construction industry. These variations ensure that the specific needs and conditions of the regional markets are met while maintaining the fundamental principles of fairness and promptness in payment practices.
Applicability
The Act applies to all parties involved in the construction process, including contractors, subcontractors, suppliers, and consultants. It is designed to be broad in its reach, ensuring that small tradespersons and large construction firms alike can benefit from its provisions. The comprehensive scope of the Act ensures that almost every professional involved in the construction industry is protected under its provisions, promoting a culture of prompt payment and fair dealing across the sector.
Key Provisions and How They Protect Subcontractors
Right to Payment:
The Act establishes a legal entitlement for subcontractors to receive payment for construction work or related goods and services provided under a contract. This is pivotal in supporting cash flow and financial stability for subcontract
Payment Claims:
Subcontractors can issue a ‘payment claim’ to the party who owes them money (often the main contractor or project owner). This claim must clearly state that it is made under the Security of Payments Act, specifying the amount due and the work it relates to.
Strict Timelines:
The Act imposes strict timelines for responding to a payment claim. The respondent must issue a payment schedule within a specified period, usually 10 to 20 business days, stating what they intend to pay and the reasons for any difference from the claimed amount.
Adjudication Process:
If there is a dispute or if payment isn’t made, subcontractors can apply for a rapid adjudication process. This process is faster and less formal than court proceedings, providing a quicker resolution to disputes.
Protection from Retaliation:
The Act protects subcontractors from punitive actions like contract termination for making a payment claim. This encourages subcontractors to assert their rights without fear of backlash.
Why is This Important for Subcontractors?
Ensures liquidity by facilitating faster payment cycles, which is essential for maintaining business operations.
Reduces financial risk by providing a clear, statutory pathway to resolve payment disputes and recover money rightfully owed.
Empowers subcontractors to assert their rights with confidence, knowing that the law supports timely and fair compensation for their work.
Understanding and leveraging the Security of Payments Act is critical for every subcontractor aiming to protect their business interests and sustain their operational capabilities in the competitive construction industry.
Steps to Take if a Dispute Arises
Disputes over payments can disrupt work and cause financial strain. Understanding the steps to take when a payment dispute arises under the Security of Payments Act can help subcontractors manage and resolve these disputes efficiently. Here’s what to do:
Step 1: Issue a Payment Claim
Begin by formally issuing a payment claim to the party owing the money. This claim must:
- Clearly state the amount due.
- Specify the work or services it relates to.
- Indicate that it is made under the Security of Payments Act.
- Be served within the time frame specified in your contract or, if not specified, within the default periods set by the Act.
Step 2: Await the Payment Schedule
The party receiving the payment claim must respond within a set period (typically 10 to 20 business days, depending on the state legislation) with a payment schedule. This schedule should:
- State the amount they agree to pay.
- Detail the reasons for any amount that differs from what was claimed.
- Be provided even if the full amount claimed is being released.
Step 3: Apply for Adjudication
If the response via the payment schedule is unsatisfactory, or if no payment schedule is received by the deadline, you can apply for adjudication. To do this:
- File an application with an authorized nominating authority.
- Ensure all necessary documents and evidence supporting your claim are included.
- Submit the application within the required timeframe after the due date for the payment schedule or the response.
Step 4: Adjudication Process
After the application, an adjudicator is appointed to review the case. The process usually involves:
- Examination of submitted documents and claims.
- Possibly a meeting with both parties.
- A decision made usually within 10 business days after the adjudication application is accepted.
Step 5: Follow Through on the Adjudication Decision
The adjudicator’s decision is interim binding, which means it is enforceable until the dispute is finally resolved through legal proceedings or by agreement. If the adjudication is in your favor and the other party does not comply with the decision, you can:
- Issue a statutory demand for payment.
- Seek enforcement through a court, which may include filing for a judgment based on the adjudicator’s decision.
Step 6: Consider Further Legal Action
If necessary, further legal action can be pursued to enforce the decision or address any ongoing disputes. This might involve:
- Engaging a lawyer to begin court proceedings.
- Seeking additional orders for payment, including interest and costs.

What is a payment claim?
A payment claim is a written document issued by a subcontractor to claim payment for construction work or related goods and services provided under a contract. It must clearly specify the amount being claimed and indicate that it is made under the Security of Payments Act.
How often can I submit a payment claim?
Under most state legislations, you can submit a payment claim every month or as per the intervals agreed upon in your contract. If your contract does not specify, the default period is typically monthly.
What should I do if I do not receive a payment schedule?
If you do not receive a payment schedule within the time frame specified by your state’s legislation (usually 10-15 business days), the full amount of your payment claim becomes due and payable. You can then proceed to apply for adjudication to resolve the dispute.
What is the adjudication process?
Adjudication is a quick dispute resolution process provided under the Act, where an independent adjudicator is appointed to resolve payment disputes. The process involves submitting an adjudication application, after which the adjudicator reviews the case and makes a decision within a specified period, generally 10-28 days, depending on the state.
How long do I have to enforce an adjudication decision?
Once an adjudication decision is made, it is binding and must be complied with immediately. If the decision is not complied with, you can take further legal steps to enforce the decision. Typically, you should initiate enforcement actions within 12 months of the adjudication decision.
Can I stop working if I’m not paid?
Yes, the Security of Payments Act allows you to suspend work if a payment due under a payment claim is not made by the due date and no payment schedule has been provided. It is advisable to notify the other party in writing of your intention to suspend work due to non-payment.
What are my rights if the contract is terminated?
If your contract is terminated, you still retain the right to make a payment claim for any unpaid work completed up to the date of termination. The provisions of the Act continue to apply, ensuring you can seek payment for work done.
Does the Act apply to all types of construction contracts?
The Act applies broadly to all construction contracts related to building, construction, engineering, and related supply or consultancy services. There are some exceptions, such as contracts solely for residential building work on the part of the homeowner.
What should I include in a payment claim?
A payment claim should include:
- A detailed description of the construction work or related goods and services provided.
- The amount of payment being claimed.
- A statement that the claim is made under the Security of Payments Act.
