The Security of Payment Act (SOPA) is one of the most important legislative tools available to construction professionals in New South Wales. It’s designed to ensure that contractors, subcontractors, and suppliers are paid promptly for the work they complete.
What is the Security of Payment Act?
SOPA establishes a legal framework for handling progress payments under construction contracts. It sets out the rules for how and when claims can be made, how those claims should be responded to, and what happens if there’s a disagreement.
A core feature of SOPA is the “payment claim” — a formal notice issued by a party seeking payment. The responding party must then issue a “payment schedule” within strict timeframes. If they don’t respond or pay, the claimant can seek adjudication.
This process helps keep the money flowing on projects, while providing a fair and structured way to resolve issues.
Who is Covered by SOPA?
SOPA applies to nearly all construction-related contracts in NSW, including those for construction work, consultancy services, and the supply of related goods.
Whether you’re a head contractor, subcontractor, engineer, or material supplier, if you’ve provided services under a construction contract, SOPA likely applies to you.
It’s important to note that the Act covers both written and oral agreements — so even handshake deals may still fall under its jurisdiction.
Key Timeframes You Need to Know
Timing is everything under SOPA. Missing a deadline — even by one day — can jeopardize your rights. Here’s a quick breakdown of the key milestones:
- Payment Claim: Can be issued monthly (or per contract terms).
- Payment Schedule: Must be submitted within 10 business days.
- Adjudication Application: Lodged within 10 business days after payment is missed or denied.
- Adjudicator’s Decision: Usually delivered within 10 days after they accept the application.
Each of these steps involves strict compliance. Even minor mistakes can result in losing your claim or being exposed to summary judgment.
Common Pitfalls to Avoid
Many businesses lose their SOPA rights due to simple, avoidable missteps. One of the most common issues is failing to submit a payment schedule in time. If you don’t respond to a payment claim, you may be liable for the full amount, even if the claim is disputed.
Another frequent mistake is assuming that SOPA only applies to large, formal contracts. In reality, even small or informal projects can trigger SOPA protections.
Lastly, many businesses wait too long before seeking advice — by the time they do, deadlines may have passed.
