NCAT Evidence Requirements for Consumer Claims

How Evidence Works at NCAT

NCAT does not follow the strict rules of evidence that apply in courts. Under section 38 of the Civil and Administrative Tribunal Act 2013 (NSW), the tribunal can inform itself on any matter it considers appropriate and is not bound by the rules of evidence. That means hearsay, screenshots, and informal documents can all be admitted.

But "not bound by the rules of evidence" does not mean "anything goes." The tribunal member still decides how much weight to give each piece of evidence. A clear, organised bundle with original documents carries far more weight than a stack of blurry screenshots presented for the first time at the hearing.

Types of Evidence the Tribunal Accepts

Written documents form the backbone of most consumer claims: contracts, invoices, receipts, email correspondence, text messages, quotes and warranty documents. Print them in chronological order with page numbers.

Photographs and video are essential for defective goods, damaged property and unfinished work. Take photos in good lighting, include close-ups of the defect alongside wider shots showing context, and note the date each photo was taken. Save the originals — the tribunal may ask about metadata.

Expert reports carry significant weight, particularly in motor vehicle and building disputes. An independent mechanic's inspection report or a building consultant's defect assessment can establish whether a failure is "major" or "minor" under the Australian Consumer Law. Under NCAT Procedural Direction 3, the expert must include a declaration that they have read and agreed to be bound by the Expert Code of Conduct. Reports without this declaration can be ruled inadmissible.

Witness statements should be in writing, signed and dated. The witness must attend the hearing — in person or by video link — to confirm their statement and answer questions. If a witness refuses to attend voluntarily, you can apply for an NCAT summons (A$59 fee) to compel their attendance, as long as you also pay conduct money for their travel costs.

Organising the Evidence Bundle

After conciliation fails, the tribunal issues procedural directions setting deadlines for evidence exchange. The standard pattern: the applicant files and serves their bundle first (typically 21 days before the hearing), then the respondent files and serves theirs (7 to 14 days before the hearing).

Your bundle should include:

1. An indexed table of contents listing every document with a short description
2. Consecutive page numbers across all documents
3. A chronological factual timeline summarising what happened and when
4. The documents themselves, grouped logically — contract, payment proof, correspondence, defect evidence, expert reports, loss calculations

Serve a complete copy on the respondent and file the original with the NCAT Registry by the deadline in your directions. Late evidence that was not served in time can be refused admission at the member's discretion under Procedural Direction 8.

Common Mistakes

Arriving at the hearing with a folder of unsorted receipts is the most common problem. The member has limited time and cannot piece together your case from a disorganised pile. Equally, presenting evidence that you never served on the other side gives the respondent grounds to object — and the member may exclude it.

The other trap is over-relying on text messages and social media screenshots without context. A screenshot of a WhatsApp conversation is useful, but print the entire relevant thread, not cherry-picked messages. The respondent will have the same conversation and can point to anything you left out.
