Unpaid Invoice Small Claim Northern Territory

A contractor who took your deposit and disappeared, a client who has ignored your invoices for months, a business that promised a refund and never delivered — these are the claims NTCAT was built for. The Northern Territory Civil and Administrative Tribunal hears small claims up to $25,000, and unpaid invoices and unreturned deposits make up a large share of the caseload.

Before You File: The Demand Letter

NTCAT practice directions expect you to make a genuine attempt at resolution before filing. Write a formal letter of demand that identifies the correct legal name of the debtor, states the exact amount owed with an itemised calculation, gives at least 14 clear calendar days to pay, and explicitly warns that you will file at NTCAT if payment is not received. Send it by registered post and keep the tracking receipt.

If the debtor is a company, verify the registered company name and ACN through an ASIC search before sending the demand. Addressing it to the trading name rather than the legal entity weakens both the demand and any subsequent filing.

Filing at NTCAT

Complete Form 1 — Initiating Application. In Part F, state the principal amount claimed. If you are chasing a $4,500 unpaid invoice, that is $4,500. If a contractor took a $6,000 deposit and did no work, the claim is $6,000. You can also claim pre-filing disbursements (the filing fee and service costs) under s 132(2)(ba) of the NTCAT Act 2014 — tick "YES" in Part F to include them.

In Part G, write a concise one-page summary: the date of the contract or agreement, what was supposed to happen, what actually happened (or did not happen), the date payment became due, and the amount outstanding. Do not attach evidence at this stage.

Filing fees for an individual applicant:

• Claim under $2,000: $129
• Claim $2,000 – $10,000: $259
• Claim over $10,000: $518

Contractor Deposits That Were Never Returned

Contractor deposit claims have an additional wrinkle: you need to establish what the deposit was for, that the work was not completed (or was never started), and that the contractor has not returned the money. Photographs of incomplete or defective work, the written quote or contract, any text messages or emails discussing the job, and a timeline of events form the core of your evidence.

If the contractor argues they did partial work and earned part of the deposit, bring a quote from another contractor for the cost to complete or rectify the job. The difference between the deposit and the reasonable value of work actually done is what you can claim.

What Happens After Filing

Serve the respondent with the sealed Form 1 and standard orders. If they do not file a Form 2 Response within the deadline (typically 14–28 days), apply for a default decision by filing Form 7. If they respond, NTCAT schedules a compulsory conference — an informal settlement discussion — followed by a final hearing if the conference does not resolve the matter.

The Limitation Period

Under the Limitation Act 1981 (NT), you have three years from the date the debt became due to file. For an invoice with 30-day payment terms issued on 1 June 2023, the debt became due on 1 July 2023, and you have until 1 July 2026 to file. A part-payment or written acknowledgment of the debt restarts the three-year clock; demand letters and phone calls do not.

Can You Recover Legal Costs?

NTCAT's default position is that parties bear their own costs. You will not recover solicitor fees from the respondent except in limited circumstances, including unconscionable conduct, frivolous litigation, or an unreasonable refusal to comply with directions. You can recover out-of-pocket disbursements — the filing fee, process server costs, and ASIC search fees — under s 132(2)(ba). This is why hiring a lawyer for a small unpaid invoice claim is rarely cost-effective, and why NTCAT is designed for self-representation.

The NTCAT Small Claim Filing Guide covers the complete process from demand letter to hearing, with a claim calculation worksheet and evidence organiser built for unpaid invoice and deposit recovery claims.
