Free New South Wales Trailer Bill of Sale
Trailer sales in NSW use the VIN (or serial number for trailers without a standard VIN) as the identifier and are processed through Service NSW. All trailers used on public roads must be registered. The seller should lodge a Notice of Disposal, the buyer must complete the Change of Ownership within 14 days, and stamp duty at 3% applies to the assessed value. NSW's no-separate-title system means the Certificate of Registration is the ownership document for trailers as well as cars.

New South Wales Trailer Bill of Sale — What You Need to Know
Stamp Duty / Tax Details
NSW stamp duty applies to trailers on the same sliding scale as other registered vehicles: 3% on the first $45,000 of value, plus 5% above $45,000. Most private trailer sales fall well under the $45,000 threshold.
Inspection / Roadworthy Requirements
No mandatory safety inspection for trailer transfers in NSW. The buyer is responsible for ensuring the trailer is roadworthy — lights, safety chains, brakes (if applicable), and tyres — before towing on NSW public roads.
New South Wales Trailer Sale — Step-by-Step Checklist
- Locate the VIN or serial number from the trailer's compliance plate or frame stamp and verify it against any existing registration documents.
- Complete a bill of sale with the VIN or serial number, trailer type, make, year (if known), ATM (Aggregate Trailer Mass), and agreed sale price.
- Seller provides the Certificate of Registration to the buyer and lodges a Notice of Disposal at service.nsw.gov.au within 7 days.
- Buyer completes the Change of Ownership at Service NSW within 14 days, paying 3% stamp duty on the sale price or assessed market value.
- Confirm trailer lights (brake lights, turn signals, tail lights), safety chains, and brakes (if ATM requires them) are operational before towing on NSW roads.
- Both parties retain signed copies of the bill of sale.
Common Pitfalls
- Missing the Notice of Disposal: the seller remains linked to the trailer registration until the NoD is filed. Any infringements or incidents involving the trailer after the sale can be directed to the seller.
- Missing ATM documentation: ATM (Aggregate Trailer Mass) determines whether trailer brakes are required. If the compliance plate is missing or damaged, the buyer may be unable to register the trailer without an inspection.
- Towing before registration: NSW requires all trailers towed on public roads to be registered. The buyer should not tow the trailer on public roads until the Change of Ownership is completed.
- Using an incorrect identifier: trailers with a standard 17-character VIN should use that. Older or imported trailers may have only a manufacturer serial number — use whatever is stamped on the compliance plate.
Pro Tip
NSW trailer sales follow the same two-deadline rule as car sales: seller lodges Notice of Disposal within 7 days, buyer completes Change of Ownership within 14 days. Stamp duty is 3% of assessed value for most trailers. Confirm the ATM on the compliance plate — it's needed for registration and determines brake requirements.
