Step-by-Step: Taking a Contractor to NCAT for Incomplete Building Work

A contractor who abandons your building project or leaves work incomplete can cost you thousands in delays, remedial work, and stress. In New South Wales, the Civil and Administrative Tribunal (NCAT) Home Building Division provides a faster, cheaper alternative to court for disputes under $500,000. This guide shows you exactly how to take a contractor to NCAT for incomplete building work.

Before you file: what you need to know

NCAT’s Home Building Division handles residential building disputes between homeowners and licensed contractors. You can use it when:

• Work has been abandoned or left incomplete
• The contractor refuses to finish or remedy defects
• You have paid for work that was never done
• The contract value is under $500,000

You cannot use NCAT if:

• The contractor is unlicensed (that becomes a Fair Trading complaint)
• The dispute involves commercial property
• You are seeking damages over $500,000 (Supreme Court jurisdiction)
• The work was done more than 6 years ago (limitation period applies)

Check the contractor’s licence status on the NSW Fair Trading website before you proceed. If they are unlicensed, you may need to pursue Fair Trading action or a claim against the Home Building Compensation Fund.

Step 1: Send a letter of demand

NCAT expects you to attempt resolution before filing. A properly drafted letter of demand strengthens your case by showing you tried to settle.

Your letter should:

• Identify the contract and the work that remains incomplete
• Specify exactly what you want (completion, refund, or damages)
• Cite the relevant breach (failure to complete work in accordance with the contract)
• Give a reasonable deadline (14 days is standard)
• State that you will file at NCAT if they do not respond

Send it via registered post or email with read receipt. Keep proof of delivery.

If the contractor ignores your letter, you have evidence of their non-cooperation. If they respond, document everything — those communications become part of your tribunal evidence.

Step 2: Gather your evidence

NCAT decisions are based on the evidence you present. Start building your file immediately.

Essential documents:

• The signed contract or written quote
• All invoices, receipts, and proof of payment
• Correspondence (emails, texts, letters) with the contractor
• Photos and videos showing the incomplete or defective work
• Any building plans, specifications, or scope of work documents

Supporting evidence:

• Expert reports (if you have had a building inspector assess the work)
• Quotes for rectification or completion by another contractor
• Diary notes or records of site visits, delays, or missed appointments
• Statutory declarations from witnesses (neighbours, tradespeople, family members who saw the state of the work)

Organise everything chronologically. NCAT members appreciate clear, well-indexed evidence bundles. If you have dozens of photos, create a summary document with captions and dates.

Step 3: Calculate your claim

You need a specific dollar figure. NCAT does not award vague or unquantified claims.

Common claim types:

• Cost to complete: Get quotes from other licensed contractors to finish the work. Use at least two quotes if possible.
• Rectification costs: If the work is defective, get quotes to fix it properly.
• Refund of money paid: If you paid for work that was never done, claim the exact amount with proof of payment.
• Consequential losses: Additional costs caused by the contractor’s breach (temporary accommodation, storage, wasted materials). These must be reasonably foreseeable and directly linked to the breach.

Do not inflate your claim. NCAT can reduce awards if they find your figures unreasonable.

Step 4: Lodge your NCAT application

You file online through the NCAT website or by post. The application form is called a “Home Building Application.”

What you need to complete the form:

• Your details (applicant)
• Contractor’s details (respondent) — full legal name, ABN, licence number, address
• A clear summary of the dispute (keep it factual, not emotional)
• The amount you are claiming
• What orders you want NCAT to make (e.g., “Order the respondent to pay $18,500 for the cost of completing the work”)

Filing fee:

• Claims under $10,000: $99
• Claims $10,000 to $30,000: $198
• Claims over $30,000: $495

Fee waivers are available if you hold a Centrelink concession card.

Once lodged, NCAT will send a copy of your application to the contractor. They have 28 days to file a response.

Step 5: Prepare for the hearing

NCAT will schedule a directions hearing or proceed straight to a final hearing depending on the complexity of your case.

Directions hearing:

This is a case management session where the tribunal member checks whether both parties are ready, identifies the issues in dispute, and sets a timetable for evidence. You do not need a lawyer, but you must attend (in person or by phone).

Final hearing:

This is where your case is decided. You will present your evidence, the contractor will present theirs, and the tribunal member will ask questions.

How to prepare:

• Prepare a written outline of your case (a simple chronology and summary of the key facts)
• Bring three copies of all evidence (one for you, one for the tribunal, one for the contractor)
• Rehearse your key points — you will have limited time to speak
• Be ready to answer questions about costs, timelines, and what you did to mitigate your loss

If you have an expert report, the expert may need to attend to give evidence. Arrange this in advance.

Step 6: Attend the hearing

NCAT hearings are less formal than court, but you still need to be organised and respectful.

What to expect:

• The tribunal member will introduce themselves and explain the process
• You will be asked to present your case first (you are the applicant)
• The contractor will respond
• The tribunal member may ask both parties questions
• You may be given a chance to reply briefly

Tips:

• Stick to the facts. Do not rant about how the contractor ruined your life.
• Refer to your evidence by document number or page number.
• Answer questions directly. If you do not know, say so.
• Stay calm even if the contractor lies or exaggerates. The tribunal member will assess credibility.

Most hearings are completed in one session. Complex cases may be adjourned for further evidence.

Step 7: The decision and enforcement

NCAT typically delivers its decision within 28 days. You will receive a written order setting out the tribunal’s findings and what the contractor must do.

If you win:

The contractor is legally required to comply with the order. If they do not pay or complete the work within the specified time, you can enforce the order through:

• A writ of execution (seizing assets)
• A garnishee order (taking money from their bank account)
• A payment arrangement if they request one

Enforcement is done through the NSW Sheriff’s Office or Local Court, not through NCAT itself.

If you lose:

You can appeal to the NCAT Appeal Panel, but only on a question of law or if there was a serious procedural error. You cannot appeal just because you disagree with the decision.

Common mistakes to avoid

Not keeping records: If you paid cash with no receipt, or agreed to variations verbally with no written confirmation, your case becomes much harder.

Filing too early: If the contractor is still on site and trying to finish, give them a reasonable chance. NCAT may dismiss your application as premature.

Claiming for things outside NCAT’s jurisdiction: NCAT cannot award damages for emotional distress, punish the contractor, or cancel their licence. Stick to financial loss.

Poor evidence: Blurry photos, missing invoices, or vague witness statements weaken your case.

Frequently Asked Questions

How long does an NCAT building dispute take from filing to decision?

Simple cases are typically heard within 3-6 months of filing. Complex disputes involving expert evidence or multiple parties can take 9-12 months. NCAT prioritises cases where work is ongoing or there is urgent need for orders.

Can I take an unlicensed contractor to NCAT for incomplete work?

No. NCAT’s Home Building Division only has jurisdiction over licensed contractors. If your contractor is unlicensed, you must lodge a complaint with NSW Fair Trading and may be able to claim against the Home Building Compensation Fund if the work meets the threshold requirements.

Do I need a lawyer to represent me at NCAT?

No. NCAT is designed for self-representation. You can bring a lawyer or building consultant to assist you, but most homeowners present their own cases successfully. The tribunal member will guide you through the process and ask questions to clarify the evidence.

What happens if the contractor does not show up to the NCAT hearing?

NCAT can proceed in their absence and make orders based on your evidence alone. The contractor loses their chance to defend the claim. If they have a reasonable excuse for non-attendance, they can apply to set aside the decision, but this is rare.

Can I claim for the time I took off work to deal with the incomplete building work?

Generally no. NCAT awards compensation for direct financial loss (cost to complete, rectification, wasted materials) and reasonably foreseeable consequential losses (temporary accommodation if the house was uninhabitable). Lost wages for your own time are not usually recoverable unless you can show a specific contractual entitlement.
