Contractor Dispute New South Wales: How to Recover Payment Without Going to Court

You finished the job. The client refuses to pay. Now what?

New South Wales contractors have stronger legal protections than most other creditors. The Home Building Act and the Building and Construction Industry Security of Payment Act give contractors specific ways to pursue payment.

Get the forum right first. If you are the business that is owed money, an unpaid invoice is generally a debt claim for the Local Court of New South Wales, not NCAT. The exception is residential building work for a homeowner, which NCAT can hear as a home building claim under the Home Building Act 1989.

Start With a Letter of Demand

Send a formal letter of demand before escalating to tribunals or courts. It is the usual first step, and it often gets the invoice paid without any claim.

A properly drafted demand letter:

• States exactly what you are owed and why
• References the contract, quote, or invoice
• Cites the applicable New South Wales legislation
• Sets a clear deadline for payment (typically 7-14 days)
• Warns of the next step if payment is not made

It shows the debtor you are serious and sets out what happens next.

New South Wales-Specific Legal Protections for Contractors

New South Wales law gives contractors several advantages when recovering payment for building and construction work.

Home Building Act

The Home Building Act regulates residential building work in New South Wales. It covers contracts over $5,000 and requires builders to hold home warranty insurance for jobs over $20,000.

Key provisions for payment disputes:

• Progress payments: under a residential building contract, progress payments can generally be claimed only for work already done, as the contract provides
• Retention amounts: if the contract lets the client hold back a retention, check the contract for when it must be released
• Statutory warranties: All residential building work carries implied warranties — work must be done with due care and skill, be suitable for its purpose, and comply with plans and the Building Code

If the client withholds payment over alleged defects, they will need evidence of the defects, and you will need evidence the work was done as agreed. Where the work substantially complies, the usual result is payment less the reasonable cost of fixing any genuine defects.

Building and Construction Industry Security of Payment Act

The Security of Payment Act (SOPA) is the most powerful tool for New South Wales contractors. It applies to construction work and related goods and services, whether residential or commercial.

SOPA allows you to:

• Serve a payment claim on and from the last day of each month in which you did work (or an earlier date if the contract allows)
• If the client does not provide a payment schedule within 10 business days (or sooner if the contract requires), you can sue for the claimed amount as a debt, or give notice and then apply for adjudication
• The adjudicator typically decides within 10 business days
• The determination is enforceable as a court judgment

SOPA prioritises speed over detailed factual disputes, which suits a contractor who has done the work and has not been paid.

When to use SOPA: If you are owed money for construction work and the client is disputing the amount or refusing to pay, a SOPA payment claim is usually quicker than a court or tribunal claim.

When not to use SOPA: SOPA does not apply to employment disputes, or if the contract is not for construction work. It also does not resolve final disputes about defects or contractual entitlements — it only determines what must be paid now, with final rights preserved for later.

If the Demand is Ignored: NCAT or the Local Court?

If your letter of demand does not result in payment, the next step depends on the kind of work and who the client is.

NCAT’s consumer claims run one way: they are brought by a consumer about goods or services supplied to them (Fair Trading Act 1987, s 79E). A contractor chasing a client for payment is not a consumer, so outside residential building work for a homeowner, an unpaid contractor invoice is a debt claim for the Local Court.

Local Court of New South Wales: commercial and other contractor debts

For commercial work, work for another business, or any other unpaid contractor invoice, you claim in the Local Court.

Small Claims Division (up to $20,000):

• Proceedings are less formal and less technical, and the rules of evidence do not apply
• No lawyers required (though you can bring one)
• A defended claim goes to a pre-trial review first, where the parties are helped to reach agreement

General Division (over $20,000 up to $100,000):

• More formal process than the Small Claims Division
• Claims above $100,000 go to the District Court (up to $750,000)

A Local Court claim is started with a statement of claim, which you can file through the NSW Online Registry.

NCAT home building claims: residential work for a homeowner

Residential building work is its own case type, and NCAT’s home building page lists “payment for home building work or services” among the orders it can make, with “recovery of a debt by a contractor” exempt from the Fair Trading referral step. A contractor chasing a homeowner for residential building work can therefore be in NCAT, under the Home Building Act 1989, rather than the Local Court.

When a home building claim at NCAT fits:

• The contract is for residential building work for a homeowner
• The client claims defects and refuses to pay
• The dispute involves Home Building Act warranties

Filing fees change each financial year; check the current fee on the Local Court’s site (or NCAT’s, for a home building claim) before you file.

Getting Paid After a Judgment or Order

Winning and being paid are separate events. A Local Court judgment is enforced through the Local Court; an unpaid NCAT money order is registered with the Local Court and enforced there (see Step 5).

Practical Steps to Recover Payment in New South Wales

Step 1: Send a letter of demand

• State the amount owed, reference the contract or invoice
• Cite relevant New South Wales legislation if applicable
• Set a 7-14 day deadline
• Warn of adjudication or a court claim (or NCAT, for residential work for a homeowner) if payment is not made

Step 2: Serve a SOPA payment claim (if applicable)

• Use this if the debt relates to construction work
• Serve the payment claim on the client
• If the client does not provide a payment schedule within 10 business days (or sooner if the contract requires), you can sue for the claimed amount as a debt, or give notice and then apply for adjudication
• The adjudicator’s determination is binding and enforceable

Step 3: Start a claim in the right forum (if SOPA does not apply or you prefer a court process)

• Commercial or other contractor debt: file a statement of claim in the Local Court, through the NSW Online Registry
• Residential building work for a homeowner: apply to NCAT as a home building claim
• Have the contract, invoices, photos and correspondence ready
• Serve the claim on the client

Step 4: Attend the pre-trial review or hearing

• Present your case clearly and factually
• Bring all evidence organised and referenced
• Be prepared to answer questions about the work, the contract, and any defects claimed by the client

Step 5: Enforce the judgment or order

• If you win and the client still does not pay, enforce through the Local Court (registering an NCAT money order there first)
• Options include garnishee (seize money from their bank account), writ of execution (seize property), or examination notice (require them to disclose their finances)

Common Defences Clients Raise (And How to Counter Them)

“The work is defective”

• Provide evidence the work complies with the contract and Building Code
• Offer to rectify minor defects (if genuine)
• Point out that payment is still due for work that substantially complies

“You did not finish the job”

• Show what percentage of work was completed
• Explain why the job was not finished (client refused access, client did not pay progress claims, etc.)
• If the contract was ended because of the client, you may be able to claim for the work done; how much depends on the contract terms, so get advice

“The quote was an estimate, not a fixed price”

• Refer to the written contract or quote
• If it says “estimate,” you must prove the final amount is reasonable
• If it says “fixed price”, the agreed price applies, adjusted only for variations made under the contract and any genuine defect or delay claims

“You took too long”

• Show the delays were caused by the client (late decisions, site access issues, weather)
• Refer to any extension of time clauses in the contract
• Argue that time was not of the essence unless the contract explicitly said so

“I already paid you”

• Demand proof of payment (bank statement, receipt)
• If they paid a deposit, show the balance still owing
• If they claim cash payment, ask why there is no receipt

Frequently Asked Questions

Can I use the Security of Payment Act for residential building work in New South Wales?

Yes. The owner-occupier exclusion (former s 7(2)(b)) has been repealed, so the Act covers residential work for homeowners as well as commercial work, subject to the Act’s other exclusions. If you are owed money for building, trade, or construction-related services, you can serve a payment claim under SOPA regardless of whether the project is a home renovation or a commercial build.

Can I take a client to NCAT for an unpaid contractor invoice?

Only for residential building work for a homeowner. NCAT’s home building case type covers payment for home building work, including debt recovery by a contractor, under the Home Building Act 1989. Other contractor and commercial debts go to the Local Court: the Small Claims Division up to $20,000 and the General Division over $20,000 up to $100,000.

What if the client claims the work is defective and refuses to pay?

If the client withholds payment over alleged defects, they will need evidence of the defects, and you will need evidence the work was done as agreed. Where the work substantially complies, the usual result is payment less the reasonable cost of fixing any genuine defects. If minor defects exist, you can offer to rectify them. If the client’s claim is exaggerated or false, present evidence (photos, expert reports, compliance certificates) showing the work meets the required standard.

Can I recover interest on an unpaid contractor invoice in New South Wales?

Yes. You can typically claim interest under the Civil Procedure Act from the date payment was due. The rate is prescribed and changes over time, so check the current rate before you include interest in your claim.

Do I need a lawyer to recover an unpaid contractor invoice in New South Wales?

No. Proceedings in the Local Court’s Small Claims Division (up to $20,000) are less formal and less technical, and you do not need a lawyer, though you can bring one if you choose. Claim Done drafts your letter of demand and your Local Court statement of claim, so you can file and present your case yourself.
