How to Take a Client to NCAT for Unpaid Invoices

You sent an invoice. The client acknowledged it. Weeks pass. Reminders go unanswered. A letter of demand gets ignored. Now you need to escalate — and in New South Wales, that means filing a claim with the NSW Civil and Administrative Tribunal (NCAT).

NCAT’s Consumer and Commercial Division handles unpaid invoice disputes up to $30,000. The process is faster and cheaper than court, designed for self-represented parties, and enforceable across NSW once you get an order.

When NCAT is the right forum

NCAT handles consumer and commercial disputes under $30,000. You can use NCAT if:

• The debt is under $30,000 (above that, you need the Local or District Court)
• The client is in NSW or has NSW connections
• The debt is for goods or services (not employment, family law, or criminal matters)
• You have evidence — invoices, quotes, contracts, correspondence, proof of delivery
• You tried to resolve it first

If the client is interstate, you may need to file in their home state tribunal or in a NSW court with broader jurisdiction. If the amount exceeds $30,000, the Local Court handles claims up to $100,000.

NCAT filing fees

NCAT fees are tiered by claim amount. As of 2024:

• Up to $10,000: $107 filing fee
• $10,001 to $30,000: $226 filing fee
• Hearing fee: $226 (payable if the matter proceeds to hearing)

If you win, you can ask NCAT to order the other party to reimburse your filing and hearing fees. NCAT typically orders cost reimbursement in straightforward unpaid invoice cases where the debtor had no genuine defence.

Concession rates apply for pensioners and health care card holders. Check the NCAT website for current fee schedules.

What you need before you file

Gather these before starting your application:

Basic details:

• Full legal name and ABN of your business
• Full legal name and address of the client (individual or company)
• Invoice numbers, dates, and amounts
• Total amount claimed (including interest if applicable)

Supporting documents:

• Original invoices clearly showing services rendered or goods supplied
• Quote or contract (if one exists)
• Proof of delivery — delivery dockets, signed acceptance, email confirmations
• Correspondence showing the client acknowledged the debt
• Letter of demand (if you sent one)
• Payment history (if partial payments were made)

Evidence of attempts to resolve: NCAT expects you to try negotiating before filing. Document every attempt — emails, phone call notes, SMS screenshots.

How to file your NCAT application

NCAT applications are filed online through the NSW Online Registry:

1. Create an account on the NSW Online Registry portal
2. Select the Consumer and Commercial Division
3. Choose “General” as the matter type (for unpaid invoices)
4. Complete the online form — party details, claim amount, brief description
5. Upload supporting documents (PDF format, max 10MB per file)
6. Pay the filing fee by credit card or direct debit

Once submitted, NCAT issues a case number and serves the application on the other party. The respondent has 28 days to file a response.

What happens after you file

Service: NCAT serves the application by post to the address you provided. If the respondent does not respond within 28 days, you can apply for a default judgment.

Response period: The respondent has 28 days to file a defence. If they admit the debt, NCAT may make orders by consent without a hearing. If they dispute the debt, NCAT schedules a directions hearing or proceeds directly to a final hearing.

Directions hearing: For disputed matters, NCAT often holds a directions hearing (by phone or video) to clarify issues, set deadlines for evidence, and schedule the final hearing. This is case management, not the main hearing.

Final hearing: The hearing is usually held in person at an NCAT location in Sydney or regional NSW. Some hearings are conducted by phone or video. Both parties present evidence, call witnesses if needed, and make submissions. NCAT members are legally trained but the process is less formal than court.

Hearings typically last 30 minutes to 2 hours depending on complexity.

Realistic timelines

From filing to final order:

• Undefended claim (default judgment): 6-10 weeks
• Defended claim (hearing required): 3-6 months
• Complex or multi-party disputes: 6-12 months

NCAT aims to resolve matters within 6 months, but delays occur if the respondent files late defences, requests adjournments, or if the tribunal list is backlogged.

Evidence requirements at hearing

NCAT expects you to prove:

1. A contract existed — written or verbal agreement for goods or services
2. You performed your side — delivered the goods or completed the services
3. The amount is correct — invoices match the agreed scope and price
4. Payment is overdue — the client has not paid despite the invoice terms

Bring:

• Original invoices and quotes
• Proof of delivery or completion
• Correspondence showing the client acknowledged the work
• Your own witness statement (a written account of events)
• Any witnesses who can verify the work or delivery

If the client disputes quality or claims breach of contract, be ready to respond with evidence showing you met the agreed standard.

What NCAT can order

If you win, NCAT can order:

• Payment of the debt — the full invoice amount
• Interest — typically calculated from the due date
• Reimbursement of filing and hearing fees
• Costs — in limited circumstances, if the other party acted unreasonably

NCAT cannot order punitive damages or compensation for stress. The order is limited to the debt, interest, and reasonable costs.

Enforcing an NCAT order

An NCAT order is enforceable like a court judgment. If the client does not pay voluntarily, you can:

• Register the order with Revenue NSW for enforcement by garnishment or property seizure
• Apply for a garnishee order to intercept money from the debtor’s bank account or wages
• Issue a writ for the levy of property to seize and sell assets
• Examine the debtor’s financial position through an examination hearing

Enforcement can take weeks to months depending on the debtor’s assets and cooperation.

Common mistakes to avoid

Incomplete invoices: If your invoice does not clearly describe the work, the client can argue they did not know what they were being charged for. Always include detailed line items.

No written agreement: Verbal contracts are enforceable, but harder to prove. Always confirm scope, price, and payment terms in writing — even a simple email works.

Filing too early: If you file before attempting to negotiate, NCAT may dismiss your claim or order you to mediate first. Always send at least one clear demand before filing.

Missing the limitation period: In NSW, you typically have 6 years from the invoice due date to file a claim. After that, the debt may be statute-barred.

Ignoring the response: If the client files a defence, read it carefully. If they raise genuine issues (defective work, breach of contract), be ready to respond with evidence.

When to get a lawyer instead

NCAT is designed for self-represented parties, but some cases need legal help:

• The client has filed a counterclaim — they are suing you for defective work or breach of contract
• The amount exceeds $30,000 — you need the Local or District Court
• The dispute involves complex contract interpretation — multi-party agreements, construction contracts, intellectual property
• The client is represented by a lawyer — while NCAT allows lawyers, it is rare in small claims; if they have one, consider getting one too

For straightforward unpaid invoices under $30,000 where the client has no genuine defence, you can handle NCAT yourself with properly prepared documents.

Final checklist before filing

Before you lodge your NCAT application:

• [ ] Confirm the debt is under $30,000

Frequently Asked Questions

How much does it cost to file an NCAT claim for an unpaid invoice?

NCAT filing fees in NSW are $107 for claims up to $10,000 and $226 for claims between $10,001 and $30,000. If the matter proceeds to hearing, an additional $226 hearing fee applies. If you win, you can ask NCAT to order the other party to reimburse your fees.

How long does an NCAT unpaid invoice case take?

Undefended claims (where the client does not respond) typically resolve in 6-10 weeks. Defended claims requiring a hearing take 3-6 months from filing to final order. Complex disputes can take 6-12 months depending on case management and tribunal availability.

Can I take a client to NCAT if they are based interstate?

NCAT has jurisdiction over NSW residents and businesses. If your client is based interstate, you may need to file in their home state tribunal or in a NSW court with broader jurisdiction. Check the client’s registered address before filing.

What happens if my client does not respond to the NCAT application?

If the client does not file a response within 28 days, you can apply for a default judgment. NCAT will review your evidence and, if satisfied, make an order in your favour without a hearing. You can then enforce the order through Revenue NSW.

Do I need a lawyer to take a client to NCAT?

No. NCAT is designed for self-represented parties. For straightforward unpaid invoice claims under $30,000, you can handle the process yourself with properly prepared documents. Consider a lawyer if the client files a counterclaim, the amount exceeds $30,000, or the dispute involves complex contract issues.
