NCAT does not care about your story. It cares about your evidence.
You can have the strongest case in New South Wales, but if you walk into the Consumer and Commercial Division without the right documents, organised properly, you will lose. The Member hearing your case will only consider what is in front of them — admissible, relevant, and properly presented.
This guide covers exactly what evidence you need, how to organise it, and how to avoid the mistakes that sink otherwise solid cases.
Why evidence wins NCAT cases
Every claim you make must be supported by a document, a witness statement, or both. If you say the other party breached a contract, you must produce the contract. If you claim you paid $5,000, you must produce the invoice and proof of payment. If you say the work was defective, you must produce photos or an expert report.
The burden of proof sits with the applicant. If you are bringing the claim, you must prove it on the balance of probabilities — meaning it is more likely than not that your version of events is correct.
The NCAT evidence checklist
Here is what you need, organised by document type.
1. Contracts and agreements
If your dispute involves a contract — whether written, verbal, or implied — you need proof of what was agreed.
What to bring:
- Signed contracts or service agreements
- Quotes or estimates that were accepted
- Terms and conditions (if they were provided and agreed to)
- Email or SMS exchanges confirming the arrangement
- Any amendments or variations to the original agreement
If the contract was verbal: Prepare a witness statement setting out what was agreed, when, and with whom. Include any contemporaneous notes, text messages, or emails that support your version.
2. Invoices and payment records
If money changed hands, you need proof.
What to bring:
- Invoices issued or received
- Receipts for payments made
- Bank statements showing the transaction
- Payment plan agreements (if applicable)
- Evidence of any deposits or part payments
Common mistake: Bringing an invoice without proof of payment. If you claim you paid, the tribunal needs to see the money leave your account.
3. Correspondence
Email, SMS, and written letters are often the strongest evidence in NCAT cases. They show what was said, when, and by whom.
What to bring:
- All relevant emails (print them, do not rely on a laptop)
- Text message screenshots (with timestamps visible)
- Letters sent by post (including proof of postage if disputed)
- Any formal notices (breach notices, termination letters)
- Social media messages if they are relevant to the dispute
How to organise it: Print emails in chronological order. Highlight key passages. Do not bring 200 pages of irrelevant back-and-forth — only what directly supports your case.
4. Photos and videos
Visual evidence is powerful, especially in defective work, property damage, or condition disputes.
What to bring:
- Photos of defective work, damage, or the subject matter of the dispute
- Videos showing the issue (bring them on a USB, but also print stills)
- Date-stamped images (most phones embed the date automatically)
- Before-and-after comparisons if relevant
Technical tip: Print photos in colour, A4 size, with the date and a brief caption. Do not hand the Member your phone.
5. Expert reports and quotes
If your case involves technical matters — building defects, vehicle damage, professional negligence — you may need an expert.
What to bring:
- Independent expert reports (building inspector, engineer, valuer)
- Quotes for rectification work
- Manufacturer specifications or industry standards
- Evidence of the expert’s qualifications
When you need an expert: If the other party disputes the quality of work or the cost to fix it, an independent report will carry far more weight than your opinion.
6. Witness statements
A witness statement is a written account of what someone saw, heard, or did. It must be signed and dated.
What to bring:
- Your own witness statement (covering everything you personally observed)
- Statements from anyone else who witnessed the events
- Statements from people who can verify key facts (a tradie who inspected the defective work, for example)
Format requirements: Each statement must include the witness’s full name, address, and a declaration that the contents are true. The witness must sign and date it. If the witness will not attend the hearing, their statement may still be admitted, but it carries less weight.
7. Statutory notices and compliance documents
If your dispute involves a statutory right — consumer guarantees, bond disputes, building work — bring the relevant notices.
What to bring:
- Breach of warranty notices
- Notice to remedy breach (if you issued one before filing)
- Licences, permits, or registrations (builder’s licence, trade certificate)
- Compliance certificates or building approvals
- Bond lodgement forms or rental agreements (for tenancy disputes)
Why it matters: If the law required you to give notice before taking action, and you did not, your case may fail on a technicality.
8. Proof of loss or damage
If you are claiming compensation, you must prove the amount.
What to bring:
- Receipts for money spent fixing the problem
- Quotes for future rectification work
- Evidence of lost income (if you had to take time off work)
- Medical reports (if the dispute caused injury or stress)
- Evidence of diminished value (a valuation showing your property is now worth less, for example)
Be specific: Do not claim $10,000 in damages without a breakdown. The tribunal will not guess.
How to organise your evidence for NCAT
Presenting evidence properly is as important as having it.
Create a hearing bundle
A hearing bundle is a single folder containing all your evidence, organised in chronological order, with an index at the front.
How to structure it:
- Cover page — your name, the NCAT case number, and the hearing date
- Index — a numbered list of every document in the bundle
- Your witness statement — always first after the index
- Supporting documents — in the order they are referenced in your statement
- Correspondence — emails and letters in date order
- Photos and reports — grouped by subject matter
Print three copies: One for you, one for the other party, one for the Member. Bring a USB backup in case the tribunal’s system allows electronic lodgement on the day.
Label and number every page
Each document should have a unique page number in the bottom right corner. Reference these numbers in your witness statement (“I attach a copy of the invoice at page 12”).
Highlight key passages
Use a highlighter to mark the critical parts of contracts, emails, or reports. Do not overdo it — only highlight what directly supports your case.
Common evidence mistakes that lose NCAT cases
Bringing too much irrelevant material. The Member has limited time. If you hand them 300 pages of unorganised documents, they will not read them.
No witness statement. If you do not prepare a written statement, you will have to give oral evidence on the spot. Most people perform poorly under pressure. A written statement lets you control the narrative.
Missing proof of payment. Claiming you paid without bank records is not enough. The other party will deny it, and you will have no comeback.
No attempt to resolve the dispute first. NCAT typically expects you to have tried. If you filed without sending a demand letter or breach notice, the Member may adjourn the matter and order you to comply first.
Relying on verbal evidence alone. If it is not in writing, it is your word against theirs. Written evidence wins.
What happens if you do not have enough evidence?
If you arrive at NCAT without sufficient evidence, the Member may:
- Adjourn the hearing and give you time to gather more documents
- Dismiss your application for lack of proof
- Make orders based only on the evidence presented (which may not favour you)
Do not gamble. If you are missing a key document, get it before the hearing. If you cannot get it, prepare a witness statement explaining why and what the document would have shown.

Frequently Asked Questions
Can I submit evidence after the NCAT hearing has started?
Generally no. NCAT typically expects all evidence to be served on the other party and filed with the tribunal at least 7 days before the hearing. The Member may allow late evidence if there is a good reason, but it is not guaranteed. Always lodge your evidence on time.
Do I need original documents or are copies acceptable?
Copies are acceptable for most NCAT hearings, but bring originals if the other party is likely to dispute authenticity. The Member may ask to see the original if there is a challenge. Certified copies are not usually required unless specified in the directions.
What if the other party refuses to provide documents I need?
You can apply for a direction requiring them to produce documents. File a Notice of Motion asking NCAT to order disclosure. If they still refuse, the Member may draw an adverse inference against them. Do this well before the hearing date.
Can I use text messages as evidence at NCAT?
Yes. Text messages are admissible if they are relevant to the dispute. Print screenshots showing the full conversation, the sender’s number, and the date and time. Do not edit or crop messages in a way that changes the context.
How many witness statements can I submit?
There is no formal limit, but be practical. Submit one statement from yourself and one from each witness who has direct, relevant knowledge. Do not submit multiple statements saying the same thing. Quality over quantity.
