Best Way to Recover a Contractor Deposit in Queensland
If a contractor took your deposit and walked off or left the work unfinished, the best path in Queensland depends on what kind of work it was. For domestic building work — a bathroom renovation, a deck, a kitchen extension — you must go through the QBCC dispute resolution process before QCAT will accept your application. After that step, the form depends on the claim: a deposit for renovation work that was never performed follows the Form 1 consumer and trader route; other domestic building disputes use Form 26. For a dispute that is not a building dispute, use the relevant QCAT route: Form 3 for a fixed, liquidated debt or Form 1 for a consumer and trader dispute. A written demand is a practical first step, with a payment deadline typically set for 7 to 14 days.
The distinction matters because a missing QBCC outcome letter can prevent acceptance. QCAT fees are non-refundable once an application has been processed and formally accepted.
Your Options at a Glance
| Option | Cost | Timeline | Best for |
|---|---|---|---|
| Written demand letter (typically 7–14 days) | Free | Depends on delivery and response deadline | Useful first step; not a precondition for a minor debt QCAT claim |
| QBCC dispute resolution | Free | Scheduled through QBCC | Domestic or commercial building disputes |
| QCAT minor civil dispute | $96.30–$405.60 for claims up to $25,000; check schedule for higher-value Form 26 claims | Hearing date set by QCAT | Minor debt and consumer/trader claims up to $25,000; domestic building Form 26 claims have no monetary cap |
| Magistrates Court | Higher filing fees | Court listing schedule | Money claims within its $150,000 jurisdiction, including minor debt or consumer/trader claims over $25,000 |
| Hire a solicitor | $1,500–$3,500+ | Varies | Complex disputes, contested defences, amounts over $15,000 |
| Free Dispute Resolution Centre mediation | Free | Scheduled by the local centre | Neighbour and community disputes, low-value claims where both sides will engage |
Step 1: The Demand Letter (A Useful First Step)
Before filing a minor debt claim, a written demand is not explicitly required by the Queensland Civil and Administrative Tribunal Act 2009 (Qld), but it helps document what you are seeking and when payment is due. A good demand letter states:
- What you paid and when
- What work was agreed
- What was not done or was done defectively
- A specific dollar amount you are claiming
- A deadline for payment (typically 7 to 14 days)
- That you will file at QCAT if the deadline passes without payment
Send it by registered post or email (keep proof of delivery). If the contractor pays, you are done. If they ignore it or refuse, the demand letter becomes your first piece of evidence at the hearing.
Step 2: Determine Whether the QBCC Step Applies
This is where most homeowners get tripped up. The question is whether the dispute is a domestic or commercial building dispute under the Queensland Building and Construction Commission Act 1991.
QBCC dispute resolution is mandatory for domestic or commercial building disputes before filing at QCAT.
The QBCC step does not apply when the dispute is not a domestic or commercial building dispute.
If the QBCC step applies, you must:
- Issue a formal 14-day written notice of complaint items to the contractor
- Engage the QBCC early dispute resolution process
- Receive a QBCC dispute resolution outcome letter
- Attach that letter to your QCAT application (Form 1 or Form 26, depending on the dispute)
Without the QBCC outcome letter, QCAT will reject the application at intake.
If the QBCC step does not apply, use the relevant QCAT route: Form 3 for a liquidated minor debt or Form 1 for a consumer and trader dispute. Check for any other pre-filing step that applies to your dispute type.

Step 3: Filing at QCAT
Once you have checked the relevant prerequisites (including the QBCC outcome letter for a building dispute), the QCAT filing process is:
- Verify the contractor's legal identity — search ASIC and ABN Lookup to find the correct legal entity name, not the trading name on the invoice. Naming the wrong entity means the order is unenforceable.
- Choose the correct form — Form 3 for minor debts (liquidated sums), Form 1 for consumer and trader disputes (defective work or ACL claims), Form 26 for domestic building disputes.
- Lodge through QCase (the online portal, requires Digital ID) or by paper at the QCAT Principal Registry in Brisbane or a local Magistrates Court registry outside Brisbane.
- Pay the filing fee — for amounts up to $25,000, effective 1 July 2026, $96.30 for claims up to $1,000, $164.30 for claims from $1,000.01 to $10,000, and $405.60 for claims from $10,000.01 to $25,000. Check QCAT's current schedule for a Form 26 claim above $25,000.
- Serve the application on the contractor — personal service on an individual, registered post or ASIC-registered office service for companies. Complete the Form 9 Affidavit of Service.
- For a Form 3 minor debt claim, track the 28-day response period — if the contractor does not file Form 7 after service, you can apply for a decision by default on Form 6. Other dispute types have their own response procedures.
- Prepare your evidence bundle — printed, paginated, indexed. Bring copies for the tribunal member and the respondent.
- Attend the hearing — QCAT hearings are informal. You present your evidence, the respondent (if they appear) presents theirs, and the member makes a decision.
When QCAT Is Not the Right Forum
QCAT's minor debt and consumer/trader claims are capped at $25,000, excluding interest. If that type of claim is over $25,000 and up to $150,000, you have two options:
- Abandon the excess and claim $25,000 in QCAT (you forfeit the balance permanently)
- File in the Magistrates Court for the full amount (higher fees, more formal process, potentially longer timeline). For claims over $150,000, the Magistrates Court does not have jurisdiction.
For domestic building disputes, QCAT has no monetary cap — the $25,000 limit applies only to minor debt and consumer/trader disputes.
Who This Is For
- Homeowners who paid a deposit for a renovation, extension or build and the contractor abandoned the job or did defective work
- Anyone who hired a tradesperson (plumber, electrician, tiler) for residential work and did not get what was agreed
- People who paid a deposit to a landscaper, painter, or other contractor for non-building work and received nothing
- Small landlords who paid a contractor for rental property maintenance and the work was not completed
Who This Is NOT For
- Commercial building disputes that fall outside QCAT's jurisdiction (complete the QBCC process before filing where QCAT can hear the dispute)
- Insurance claims for defective work (contact your insurer first)
- Anyone whose contractor is insolvent — QCAT does not enforce monetary orders; an unpaid order must be registered in the Magistrates Court before court enforcement steps are available, and recovery from an insolvent company may be more difficult
- Employment disputes with a contractor who was actually an employee (contact the Fair Work Commission)
The DIY Risk
Filing at QCAT yourself is entirely feasible — the tribunal is designed for it — but the main risk is procedural rather than legal. Filing the wrong form, missing the QBCC step, serving the application incorrectly, or presenting evidence in the wrong format can delay or derail your claim. A new application may require another filing fee.

Frequently Asked Questions
Can I claim the filing fee back from the contractor?
In minor debt proceedings, a successful applicant can seek the QCAT application fee and certain out-of-pocket costs. QCAT does not award legal representative fees in minor civil disputes.
How long does a QCAT claim for a contractor deposit take?
The hearing date depends on QCAT's directions and listing schedule. For a Form 3 minor debt claim, the respondent has 28 calendar days starting the day after service to respond; if no Form 7 response is filed, you can apply for a decision by default on Form 6.
What if the contractor has gone out of business?
If the contractor was a sole trader, you can pursue the individual. If they operated through a company that is insolvent or deregistered, recovery may be more difficult. QCAT does not enforce monetary orders: an unpaid order must be registered in the Magistrates Court before court enforcement steps are available. Check the ASIC register before filing.
Do I need to go through the QBCC for every contractor dispute?
No. The QBCC dispute resolution step applies to domestic or commercial building disputes before filing at QCAT. A dispute that is not a building dispute follows the relevant QCAT route, such as Form 1 for a consumer and trader dispute or Form 3 for a liquidated minor debt, subject to any other required pre-filing step.
