How to Apply to QCAT for a Building Dispute in 7 Steps

If a builder has left you with defective work, an incomplete job, or cost blowouts, QCAT is Queensland’s low-cost tribunal for resolving building disputes. This guide walks you through the entire process from lodgement to hearing.

For the forms, fees and each step, see our guide to making an QCAT application.

The Queensland Civil and Administrative Tribunal (QCAT) handles building disputes involving domestic building contracts, defective work, and breaches of building standards. In domestic building disputes, QCAT has no monetary claim limit. No lawyers required, though you can bring one if you choose.

Step 1: Confirm QCAT Has Jurisdiction Over Your Dispute

Before you lodge, make sure QCAT is the right forum.

QCAT can hear:

• Defective building work (cracked tiles, uneven floors, water ingress, structural defects)
• Incomplete work where the builder has abandoned the job
• Disputes over variations, extras, or final invoices
• Breach of domestic building contract terms
• Claims for non-compliant work under the Building Code of Australia

QCAT cannot hear:

• Commercial building disputes over $50,000, unless the parties consent in writing when the application is filed
• Debt claims over $25,000 with no underlying building dispute — use the Magistrates Court
• Matters already filed in another court
• Disputes involving unregistered builders where criminal prosecution is more appropriate

Monetary limits:

• Domestic building disputes: no monetary claim limit
• Commercial building disputes: up to $50,000, or more only if the parties consent in writing when the application is filed

If your dispute involves a licensed builder and the work itself, QCAT is usually the correct venue.

Step 2: Attempt to Resolve the Dispute First

Before you can apply to QCAT about a building dispute, you must take part in the Queensland Building and Construction Commission (QBCC) dispute resolution process. QCAT needs a letter from the QBCC about the outcome of that process (or saying no process is required) when you apply; without it, QCAT may refuse or dismiss your application.

What counts as a genuine attempt:

• Written correspondence outlining the defects or issues
• A letter of demand giving the builder a reasonable deadline to fix or pay
• Emails, text messages, or meeting notes showing negotiation attempts
• The QBCC dispute resolution process and the QBCC’s letter about its outcome (required before you apply)

You must have the QBCC’s letter before lodging, and you must show you tried to resolve the dispute. Keep copies of all correspondence — you will attach these as evidence.

If the builder has ignored your letters, refused to fix the work, or denied responsibility, you have met the threshold.

Step 3: Gather Your Evidence Before You Lodge

QCAT applications are evidence-driven. The stronger your documentation, the faster your case moves.

Essential documents:

• The signed building contract (domestic building contract, quote, or scope of work)
• All invoices, receipts, and proof of payment
• Photos and videos of the defective or incomplete work (dated if possible)
• Expert reports (building inspector, engineer, or independent tradesperson assessment)
• All written correspondence with the builder (emails, texts, letters)
• Any QBCC complaint records or dispute resolution outcomes
• Quotes for rectification work from other licensed builders

Optional but powerful:

• Witness statements from neighbours, subcontractors, or other tradespeople who saw the work
• Compliance certificates or council inspection reports showing non-compliance
• Weather records if delays or defects are weather-related

Organise everything chronologically. QCAT will want to see a clear timeline from contract signing to dispute.

Step 4: Complete and Lodge the QCAT Application

QCAT applications are lodged online via the QCAT website, by post, or in person at a QCAT registry.

Which form to use:

• Form 26 – Application for domestic building dispute for a dispute about domestic building work
• Form 25 – Application for commercial building dispute for a commercial building dispute

What to include in the application:

• Your details (applicant) and the builder’s details (respondent) — full legal name, ABN/ACN, address
• A clear, factual statement of what went wrong (defects, incomplete work, breach of contract)
• The remedy you are seeking (rectification costs, refund, completion of work, damages)
• The amount claimed (be specific — attach quotes for rectification)
• A chronology of events (contract date, payment dates, defect discovery, attempts to resolve)
• List of all documents you are relying on (attach them to the application)

Filing fee: Fees change each 1 July; check the current fee on the tribunal’s or court’s website before you file.

Lodge online at www.qcat.qld.gov.au or post to the nearest QCAT registry. You will receive a reference number and a copy of your filed application within 1-2 business days.

Step 5: Serve the Application on the Builder

Once QCAT accepts your application, you must serve a copy on the builder (respondent). QCAT does not do this for you.

How to serve:

• Personal service: Hand-deliver the application and all attachments to the builder or their registered office
• Registered post: Send via Australia Post with tracking and signature confirmation
• Email: Only if the builder has previously agreed to accept documents by email

What to serve:

• The filed QCAT application (stamped copy)
• All supporting documents you attached
• Any QCAT directions or notices you received

Proof of service:

• Complete an affidavit of service (available on the QCAT website)
• File it with QCAT within 7 days of serving the builder
• Without proof of service, QCAT may dismiss your application

The builder then has 28 days to file a response.

Step 6: Attend Compulsory Conference or Mediation

QCAT will usually schedule a compulsory conference before listing the matter for a full hearing. This is an informal settlement meeting conducted by a QCAT member or mediator.

What happens:

• Both parties attend (in person, by phone, or video)
• The QCAT member facilitates negotiation
• You can settle on the spot if both parties agree
• If no settlement, the matter proceeds to a hearing

Bring to the conference:

• All your evidence (organised and ready to show)
• A clear position on what you want (dollar amount, specific rectification, timeframe)
• Authority to settle (if you are representing a company or trust)

Settlement options:

• Full or partial payment by the builder
• Agreement for the builder to return and fix the work
• Payment plan over time
• Mutual release (both parties walk away)

If you settle, QCAT will issue consent orders making the agreement legally binding. If you do not settle, QCAT will set a hearing date.

Step 7: Prepare for the QCAT Hearing

If the matter does not settle, QCAT will list it for a final hearing.

Before the hearing:

• Review all your evidence again
• Prepare a written outline of your case (optional but helpful)
• Organise witnesses if you have any (building inspectors, other tradespeople)
• Print extra copies of all documents (one for you, one for the builder, one for the tribunal)
• Rehearse your key points (what went wrong, what you paid, what it will cost to fix)

At the hearing:

• Arrive 15 minutes early
• Dress appropriately (business casual)
• Speak clearly and directly to the QCAT member
• Stick to the facts — no emotion, no exaggeration
• Refer to your evidence by document number or date
• Answer questions honestly and concisely

What QCAT will decide:

• Whether the builder breached the contract or building standards
• Whether the defects are the builder’s responsibility
• The cost of rectification (based on your quotes and expert reports)
• Whether you are entitled to damages for delay, inconvenience, or consequential loss

QCAT may deliver a decision on the day or later in writing.

How Claim Done Prepares Your QCAT Application

Frequently Asked Questions

How long does a QCAT building dispute take from lodgement to hearing?

Waiting times for QCAT building disputes vary; check QCAT’s website for current timeframes. If the matter does not settle at the compulsory conference, it goes to a hearing. Complex cases involving multiple experts or large claims may take longer.

Can I claim for rectification costs even if I have not done the repairs yet?

Yes. You can claim the estimated cost of rectification based on quotes from licensed builders or building inspectors. QCAT will assess whether the quotes are reasonable and whether the defects are the builder’s responsibility. You do not need to pay for repairs before filing, but having detailed quotes strengthens your case.

What happens if the builder does not respond to my QCAT application?

Check QCAT’s building dispute pages and any directions QCAT gives for what happens next if the builder does not respond. Always keep proof of service.

Do I need a building inspector's report to apply to QCAT?

Not mandatory, but highly recommended. A building inspector’s report provides independent expert evidence of defects, non-compliance with building standards, and estimated rectification costs. QCAT gives significant weight to expert reports, especially in disputes involving structural defects or complex building issues.

Can I represent myself at a QCAT building dispute hearing?

Yes. QCAT is designed for self-representation. You do not need a lawyer, though you can bring one if you choose. Most applicants represent themselves successfully by organising their evidence, preparing a clear timeline, and presenting the facts calmly and directly to the tribunal member.
