The construction industry is notorious for payment delays and disputes, particularly for subcontractors and suppliers.
To address this, Security of Payment (SOP) laws were introduced across Australia (and in many other regions) to ensure everyone in the construction chain gets paid fairly and on time.
If you’re a builder, subcontractor, or supplier just starting out, here’s what you need to know.
What is the Security of Payment Law?
The Security of Payment Laws in construction give contractors, subcontractors, suppliers, and consultants in the construction industry the legal right to receive progress payments for work completed or materials supplied.
The goal of these laws is to reduce payment delays, minimize payment disputes, and prevent costly project disruptions.
The laws typically apply across various construction contracts and cover payments for work done, materials supplied, and related services, supporting financial stability and project momentum in the industry.
Key features of SOP Laws
While details of SOP laws vary by state and jurisdiction, the core principles are consistent. Here are the key features every construction professional should know.
- Right to progress payments
You don’t need to wait until the end of a project to get paid. SOP laws give you the right to claim regular progress payments for work completed or materials supplied.
If you’re not sure about how SOP laws work, you should consult with a security of payments lawyer, who can help you understand everything you need to know.
- Payment claims
Any contractor, subcontractor, or supplier can issue a formal payment claim that sets out the work performed or goods supplied, the amount claimed, and the date of the claim. However, these claims must follow specific requirements under the legislation to be valid.
- Strict timelines for responses
The respondent (client, builder, or head contractor) must reply with either a full payment or a payment schedule stating how much they will pay and the reasons for withholding payment.
Failure to respond within the legislated timeframe can have serious consequences, including losing the right to dispute the claim.
- Adjudication process
If payment is withheld or delayed, SOP laws provide a fast-track dispute resolution method called adjudication. This allows an independent adjudicator to review the claim and issue a binding decision, often within weeks, rather than months or years in court.
- Enforcement of payment
If an adjudicated amount isn’t paid, the claimant can convert the decision into a court judgment, or suspend work or supply until payment is made. This ensures the claimant has practical tools to recover what they’re owed.
How the process works (simplified)
Once again, it’s important to highlight that the exact rules of the SOP laws can differ slightly between states and territories, but the basic flow will be the same. Let’s see how it works.
- Make a claim
The claimant will issue a written payment claim with the required details for work done or goods supplied. The claim must include details of the work, the amount owed, and a statement that it is made under the relevant SOP legislation.
- Receive a payment schedule
The other party (respondent) must reply within the required timeframe. They are required to either agree to pay the full amount or provide a payment schedule outlining how much they will pay and why it differs from the claim.
- Adjudication (if needed)
If the respondent fails to pay or disputes the amount, the claimant can apply for adjudication. An independent adjudicator reviews the claim, the response, and supporting evidence.
The adjudicator issues a binding decision—usually within weeks.
- Enforcing payment
If payment still isn’t made, the claimant can register the adjudicator’s decision as a court judgment, or suspend work or supply until payment is received (depending on the jurisdiction).
Common mistakes to avoid
While SOP laws are designed to protect contractors, subcontractors, and suppliers, many people still lose out because they don’t follow the rules correctly.
The system is strict which means that missing a step or deadline can mean forfeiting your rights. Here are the most common pitfalls to watch for.
Missing deadlines
One of the biggest mistakes is waiting too long to issue a payment claim or respond to one. By doing this you risk having your claims be invalid, and in turn losing the rights to adjudication.
You can easily avoid this mistake by being aware of the exact timeframes in your state and setting reminders.
Incomplete or invalid claims
Yet another common mistake is failing to include all required details (such as description of work, amount, or a reference to the SOP Act). This mistake can lead to the claim being rejected as non-compliant.
When making claims, always use a checklist or template to make sure every claim meets legal requirements.
Assuming SOP only applies to big projects
Many small contractors or suppliers think SOP laws don’t cover them. This is a huge mistake because they may be missing out on legal protections and fast dispute resolution.
It’s crucial to understand that SOP laws apply across the supply chain, regardless of project size.
If you’re working in construction, understanding your rights under Security of Payment laws is essential. Knowing how to make a claim, respond properly, and use adjudication if necessary can protect your business and ensure you get paid for the work you’ve done.
