Contractor Dispute Resolution New South Wales: From Demand Letter to NCAT

A contractor didn’t finish the job. The work is defective. The invoice is inflated. You paid upfront and they disappeared.

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

Contractor disputes in New South Wales follow a predictable escalation: demand letter, negotiation, then the NSW Civil and Administrative Tribunal if necessary. This guide covers both stages, the thresholds that matter, and the documents you need.

Common contractor disputes in New South Wales

• Incomplete work — the contractor stopped mid-job and won’t return
• Defective workmanship — the work doesn’t meet the agreed standard or building code
• Overcharging — the final invoice exceeds the quote without justification
• Breach of contract — missed deadlines, wrong specifications, or ignored warranties
• Deposit not refunded — you cancelled and the contractor kept your deposit
• Property damage — the contractor damaged your property during the work

All are breach of contract claims. The contract may be written, verbal, or implied by conduct.

Step 1: Send a letter of demand

Before filing with NCAT, send a formal demand letter. Not legally required in New South Wales, but commercially sensible and often required by insurers if you later claim costs.

A demand letter:

• States the facts — what was agreed, what was paid, what went wrong
• Identifies the breach — which contract term was violated
• Quantifies the loss — refund, cost to rectify, or damages claimed
• Sets a deadline — typically 7 to 14 days
• States the consequence — NCAT filing if unresolved

Send via email and registered post to the contractor’s last known address. Keep proof of delivery.

Claim Done generates contractor demand letters in about 5 minutes. Tell us about your quote, invoice, photos of defective work, and correspondence. Our Programmatic Algorithms draft a letter citing Australian Consumer Law and contract principles, then deliver it by email.

Step 2: Wait for a response

Common responses:

• Full payment — dispute resolved
• Offer to rectify — the contractor agrees to fix defects at no cost
• Counteroffer — partial refund or revised scope
• Dispute the claim — denies liability or disputes the amount

If the contractor offers to rectify, get it in writing with a firm deadline. If they miss it, proceed to NCAT.

If they dispute the claim, assess whether their position has merit. Genuine disputes — for example, you changed scope mid-job and they have evidence — may warrant negotiation. Spurious disputes warrant NCAT.

Step 3: File with NCAT if necessary

The NSW Civil and Administrative Tribunal hears contractor disputes in the Consumer and Commercial Division.

NCAT thresholds

• Consumer claims up to $100,000 — Consumer and Commercial Division
• Home building claims — a separate list in the Consumer and Commercial Division; check NCAT’s website for the limits that apply

The process is designed for self-representation.

What NCAT can order

• Money judgment — the contractor must pay the amount owed
• Work order — the contractor must complete or rectify the work
• Contract termination — the contract is void and deposits refunded
• Damages — compensation for loss, inconvenience, or cost to engage another contractor

NCAT cannot award punitive damages or legal costs except in limited circumstances.

NCAT filing requirements

To file a claim:

1. Completed application form — available on the NCAT website
2. Filing fee — for general consumer or commercial proceedings, $64 for claims not more than $10,000, $133 for claims over $10,000 to $30,000, and $344 for claims over $30,000; check NCAT’s website for the current fee for home building claims
3. Supporting documents — contract, quote, invoice, correspondence, photos, bank statements
4. Evidence of demand — proof you sent a demand letter and gave the contractor opportunity to respond

File online via the NCAT portal or by post.

Evidence checklist for contractor disputes

• Written contract or quote — signed or emailed agreement
• Proof of payment — bank transfer, invoice, receipt
• Correspondence — emails, texts, WhatsApp showing the dispute
• Photos or video — defects, incomplete work, property damage
• Expert report — for building defects, get a licensed builder to inspect and quote rectification cost
• Comparable quotes — if claiming cost to complete, get quotes from other contractors

The more contemporaneous evidence, the stronger your case. NCAT members are experienced in construction disputes and assess whether work met the standard a reasonable person would expect.

NCAT hearing process

NCAT hearings are less formal than court but follow a structured process:

1. Conciliation — the tribunal member attempts to facilitate settlement before the hearing
2. Opening statements — each party summarises their case (5 minutes each)
3. Evidence — you present documents, photos, and witness testimony
4. Cross-examination — the contractor questions your evidence, you question theirs
5. Closing submissions — each party summarises why they should win
6. Decision — delivered on the day or reserved for later

Most hearings last 1 to 2 hours. Bring three copies of all documents — one for you, one for the contractor, one for the tribunal.

Common defences contractors raise

• Scope creep — you changed the job mid-contract without paying for extras
• Access issues — delays caused by your failure to provide site access
• Non-payment — they stopped work because you didn’t pay an interim invoice
• Defects caused by others — the problem was pre-existing or caused by another trade
• Unreasonable expectations — the work meets industry standards

Respond with evidence. Emails showing agreed scope or bank statements showing timely payment collapse these defences.

Timeframes and deadlines

• Demand letter deadline — 7 to 14 days is standard
• NCAT filing deadline — contract claims typically have a 6-year limitation period
• NCAT hearing — waiting times vary; check NCAT’s website
• Decision — on the day or later in writing

If you win, the contractor has 28 days to comply. If they don’t pay, enforce the judgment through the Local Court.

Enforce the judgment if necessary

If you win at NCAT and the contractor still doesn’t pay, enforce through the Local Court:

• Garnishee order — the court directs the contractor’s bank to transfer funds to you
• Writ of execution — a sheriff seizes and sells the contractor’s assets
• Examination notice — the contractor is summoned to court to disclose their financial position

Enforcement adds time and cost, but is often the only way to recover from a non-compliant contractor.
