Victoria Security of Payment Act 2002: What Subbies Should Know

If you’re a subcontractor or small builder in Victoria and a head contractor owes you money, you’ve got legal teeth. Victoria’s Security of Payment Act 2002 (the Act) gives you a fast-track way to force a conversation about unpaid invoices—without going to court for months or years. Most subbies don’t know this law exists. That’s a problem.

This post walks you through what the Act does, how long you’ve got to act, and what actually happens when you make a claim.

What Is the Security of Payment Act?

Victoria’s Security of Payment Act 2002 is a state law designed to stop head contractors and developers from sitting on unpaid invoices indefinitely. It’s the Victorian version of similar laws in other states—New South Wales has the SOP Act 1999, Queensland has the Building Industry Fairness (Security of Payment) Act 2017, and so on.

The core idea is simple: if you’ve done work or supplied materials and haven’t been paid, you can lodge a formal payment claim. The person who owes you money then has a set time to respond. If they don’t, or if they dispute the claim, you can go to fast-track adjudication—a quicker, cheaper process than court.

You don’t need a lawyer. You don’t need to prove you’ll win in court. You just need to show you’ve done the work and you’re entitled to payment.

Who Can Make a Claim?

Under the Act, you can lodge a payment claim if you’re:

• A subcontractor or supplier who’s done work or supplied materials on a construction project in Victoria
• Owed money for work or goods provided under a construction contract
• Still within the claim period (more on that below)

You don’t have to be tiny. You don’t have to be a sole trader. Small builders claiming from head contractors, concreters, electricians, plumbers, scaffolders, labour-hire operators—all of these have used the Act successfully.

One important catch: the construction work must have been done in Victoria, and there must be a written or oral construction contract in place.

How Long Do You Have to Claim?

Timing matters. The Act sets strict deadlines:

1. During the contract: You can lodge a payment claim as soon as you’re entitled to payment—usually as soon as you invoice, or whenever your contract says payment is due.
2. After the contract ends: You have up to 12 months from when the contract is finished to lodge a claim.
3. The respondent’s window: Once you lodge a claim, the person who owes you money has 10 business days to respond with a payment schedule or notice of dispute.

If they don’t respond within 10 business days, your claim is deemed admitted—which is a strong position if you end up in adjudication.

The takeaway: don’t sit on this. If you’re owed money and it’s been months, you’re probably still within the 12-month window—but time does run out.

What Happens When You Lodge a Claim?

Here’s the practical flow:

You serve a payment claim. This is a formal notice, addressed to the person who owes you money, setting out what you’re owed and why. It has to be in writing and must include specific details: your name, the claimant’s details, the amount claimed, and the construction work it relates to. You can file a payment claim and have it formatted correctly the first time.

They respond (or don’t). The respondent then has 10 business days to either:

• Pay you
• Issue a payment schedule (saying when they’ll pay part or all of it)
• Issue a notice of dispute (saying they don’t think they owe the full amount)

If there’s a dispute, you can go to adjudication. This is the real power of the Act. Adjudication is faster than court, cheaper, and you don’t need a lawyer. An adjudicator (a neutral person with construction experience) hears both sides and makes a decision, usually within 28 days. That decision is binding, and if the respondent doesn’t pay after adjudication, you can enforce it in court.

Many debtors choose to negotiate or settle rather than face adjudication. That’s because adjudication is unpredictable for them and it costs money. But there’s no guarantee—some will still fight.

What If They Don’t Respond at All?

If the respondent ignores your claim and doesn’t issue a payment schedule or notice of dispute within 10 business days, the claim is deemed admitted. In adjudication, that’s a massive advantage. You’ve already won the argument on the facts—the adjudicator just has to calculate what you’re owed.

Of course, they might still not pay after an adjudication decision. But that’s a separate enforcement step, and you’ll have a formal adjudication certificate to back you up.

The Bottom Line

Victoria’s Security of Payment Act 2002 is there for a reason: to stop head contractors and builders from leaving subbies out of pocket indefinitely. It’s a legal right you already have. Using it costs time and a modest flat fee—far less than going to court or writing off the debt.

If you’re owed money in Victoria, and it’s been weeks or months without payment, the Act is worth understanding. You’ve got options that don’t require a lawyer or years in litigation.

Know your rights. Act within the timeframe. Get it done.
