How to Apply to NCAT for a Building Dispute in NSW (Step-by-Step)

If you’re dealing with defective building work, unpaid invoices, or contract disputes in NSW, the NSW Civil and Administrative Tribunal (NCAT) Consumer and Commercial Division handles building disputes up to $500,000. You don’t need a lawyer to apply, but you do need to follow the correct process and provide the right evidence.

This guide walks you through exactly how to apply to NCAT for a building dispute, what documents you need, how much it costs, and what happens after you lodge your application.

What building disputes does NCAT handle?

NCAT’s Consumer and Commercial Division hears disputes involving residential and commercial building work. Common matters include:

• Defective or incomplete building work — poor workmanship, non-compliant installations, unfinished jobs
• Breach of statutory warranties — work not done with due care and skill, not fit for purpose, materials not suitable
• Unpaid invoices — builder or tradie not paid for completed work
• Contract disputes — disagreements over scope, variations, or payment terms
• Delay or abandonment — builder walked off site or failed to complete work on time
• Insurance claims — disputes with Home Building Compensation Fund or warranty insurers

NCAT can order rectification work, compensation, or payment of money owed. The monetary limit is $500,000 for building matters.

Before you apply: try to resolve the dispute

NCAT requires you to make a genuine attempt to resolve the dispute before lodging an application. A clear written demand is usually enough.

Send the other party a letter setting out:

• What work was defective or not completed
• What you want them to do (fix the work, pay money, complete the job)
• A reasonable deadline (typically 14-21 days)

Keep a copy of the letter and proof of delivery. NCAT will ask if you attempted resolution, and your letter is evidence you did.

Step 1: Gather your evidence

NCAT decides cases based on the evidence you provide. Start collecting documents as soon as the dispute arises.

Essential documents:

• Contract or quote — the written agreement, even if it’s just an email or text message
• Invoices and receipts — all payments made, including deposits and progress payments
• Correspondence — emails, text messages, letters between you and the builder
• Photos and videos — dated images showing the defective work or damage
• Expert reports — if you’ve had another builder inspect the work, get a written report with costings
• Scope of works — plans, specifications, or any written description of what was agreed

Optional but helpful:

• Statutory declarations from witnesses who saw the work or the defect
• Quotes for rectification work from licensed builders
• Building permits or compliance certificates (or lack of them)
• Records of delays or site visits

Organise everything chronologically. NCAT members appreciate clear, structured evidence.

Step 2: Check if the builder is licensed

In NSW, anyone doing residential building work over $5,000 must hold a licence issued by NSW Fair Trading. If your builder wasn’t licensed when they did the work, you may have additional claims or defences.

Check the licence status at the NSW Fair Trading Public Register. Print a copy of the search result — it’s useful evidence.

If the builder was unlicensed, you may be entitled to additional remedies under NSW home building legislation.

Step 3: Complete the NCAT application form

NCAT applications are lodged online or by post. The online portal is faster and confirms receipt immediately.

Form: Use the General Application form on the NCAT website (ncat.nsw.gov.au). Select “Consumer and Commercial Division” and “Home Building” as the matter type.

What you’ll need to fill in:

• Your details — name, address, contact details
• Respondent’s details — the builder or company you’re making a claim against (use their registered business name and ABN if applicable)
• Orders sought — what you want NCAT to order (e.g. “Order the respondent to pay $18,000 for rectification of defective waterproofing”)
• Summary of dispute — a brief description of what happened (200-500 words is enough)
• Attempts at resolution — confirm you tried to resolve the matter and attach your demand letter

Be specific about the orders you want. NCAT can only make orders you ask for.

Step 4: Pay the filing fee

NCAT fees are set by regulation and depend on the value of your claim.

Current fees (2025):

• Claims up to $10,000: $108
• Claims $10,001 to $30,000: $232
• Claims $30,001 to $100,000: $582
• Claims over $100,000: $1,164

Fee waivers or reductions are available if you hold a Centrelink concession card or can demonstrate financial hardship. Apply when you lodge.

Step 5: Serve the application on the other party

After NCAT accepts your application, you must serve a copy on the respondent. This means delivering the application and all supporting documents to them in a way that proves they received it.

Acceptable methods:

• Registered post — send to their business address, keep the receipt
• Email — if they’ve previously agreed to accept documents by email
• Personal service — hand-deliver and have the person sign an acknowledgment

Do not rely on regular mail. NCAT requires proof of service.

Once served, file an Affidavit of Service with NCAT confirming the date, method, and address used. The form is on the NCAT website.

Step 6: Attend the directions hearing

NCAT will schedule a directions hearing within 4-8 weeks of filing. This is usually a short hearing (15-30 minutes) where the tribunal member:

• Confirms both parties understand the claim
• Identifies the issues in dispute
• Sets a timetable for filing evidence
• Lists the matter for a final hearing

Directions hearings are often held by phone or video. You don’t need to present your full case yet — just explain what the dispute is about and what orders you’re seeking.

The tribunal member may encourage the parties to settle or refer the matter to mediation.

Step 7: File your evidence bundle

After the directions hearing, NCAT will give you a deadline to file your full evidence bundle. This is typically 2-4 weeks before the final hearing.

Your evidence bundle should include:

• An indexed folder with all documents in chronological order
• A witness statement (if you’re giving evidence yourself)
• Any expert reports or quotes for rectification work
• Copies of all correspondence, contracts, invoices, and photos

Number each page and create an index at the front. Clear evidence makes your case easier to follow.

Step 8: Attend the final hearing

The final hearing is where NCAT decides your case. Hearings are usually held in person at an NCAT location, though some are conducted by video.

What to expect:

• You present your case first (10-30 minutes depending on complexity)
• The respondent presents their case
• NCAT may ask questions of both parties
• You may be cross-examined by the other party (or their lawyer, if they have one)

Speak clearly, stick to the facts, and refer to your evidence by page number. Address your submissions to the tribunal member, not the other party.

Most building dispute hearings last 1-3 hours. Complex matters may take a full day or be listed over multiple days.

Step 9: Wait for the decision

NCAT typically delivers its decision within 4-8 weeks of the final hearing. Decisions are published on the NCAT website (with names redacted) and sent to both parties.

If NCAT orders the builder to pay money or do rectification work, the order is enforceable like a court judgment. If the builder doesn’t comply, you can register the order with the Local Court and pursue enforcement through sheriff’s officers or garnishment.

Final checklist before you apply

Before lodging your NCAT application, confirm:

• ✅ You’ve attempted to resolve the dispute in writing
• ✅ You have a written contract, quote, or agreement (even if informal)
• ✅ You’ve gathered all invoices, photos, and correspondence
• ✅ You’ve checked the builder’s licence status
• ✅ You’ve identified the specific orders you want NCAT to make
• ✅ You’re within the limitation period for building disputes (typically six years)

If you’re missing key evidence or unsure whether your claim is strong enough, consider getting a brief consultation with a building lawyer before filing. For straightforward defect claims, unpaid invoices, or contract breaches, the NCAT process is designed to be accessible without legal representation.

Filing fees range from $108 for claims up to $10,000, to $1,164 for claims over $100,000. Fee waivers are available if you hold a Centrelink concession card or can demonstrate financial hardship.

Do I need a lawyer to apply to NCAT?

No. NCAT is designed for self-represented parties. You can lodge the application, present evidence, and argue your case without a lawyer. For complex disputes or high-value claims, legal advice may be helpful but is not required.

How long does an NCAT building dispute take?

From lodging the application to final hearing, most building disputes take 4-6 months. Simple matters may be resolved faster, especially if the parties settle at mediation or after the directions hearing.

What if the builder doesn't respond to my NCAT application?

If the builder doesn’t file a response or attend the hearing, NCAT can make orders in their absence based on your evidence. You must still prove your case, but the builder’s failure to participate often works in your favour.

Can I appeal an NCAT building dispute decision?

Yes. You can apply for internal review within 28 days if you believe NCAT made an error. Appeals to the NSW Court of Appeal are possible on questions of law only. Most NCAT decisions are final on factual matters.
