Navigating the legalities of selling a used car in New South Wales can seem daunting. However, with a comprehensive understanding of relevant laws and regulations, you can ensure your transaction is both compliant and successful.

This article offers a guide for doing just that – from required documents to procedural steps for a seamless process. Whether you’re new to selling vehicles or an experienced seller, this guide will give you the knowledge and confidence necessary to navigate the process like a pro.

Required Documents to Sell A Used Car

You must provide some necessary documentation to successfully sell a car in New South Wales. 

  • Proof of Entitlement or Ownership

The registration certificate is paramount, as it serves to verify your ownership and will be transferred upon the sale of the vehicle.

You may also need a statement of sale or tax invoice to prove ownership if the car is not registered, such as a motor dealer notice or sales contract.

  • Notice of Disposal

You must submit a Notice of Disposal (NOD) to Transport NSW within 14 days of the private sale. Doing so will help you avoid late lodgement fees, remove your name from the vehicle's registration, and absolve you from responsibility for any driving penalties incurred by the new driver.

Submitting a paper form will be mandatory if you do not meet the necessary qualifications. This applies to situations such as: 

  • You’re acting on behalf of a business or organisational entity
  • You don’t possess an NSW Driver’s Licence or photo ID
  • The new owner or purchases does not have an NSW Driver’s Licence
  • The buyer is a motor dealer without an NSW motor dealer licence number. 
  • Pre-purchase Vehicle Inspection

In NSW, a safety certificate known as the pink slip is highly recommended when selling light vehicles. This certifies that the car meets public road safety standards and can be used to prove its condition when transacting with potential buyers.

Pink slips are available from authorised inspection stations for $43 and come with a two–month validity period. Alternatively, you may opt for a blue slip, including safety and identity checks, currently costing $69.

  • LPG or Gas Certificate

For your car to be fitted with an LPG or gas system, you must acquire a Gas Certificate from an approved inspector. This document ensures that the vehicle abides by safety regulations and is valid for three months. 

  • Unlisting from eTag

If you have been paying tolls via your eTag account, it is time to close it. You may do so either by accessing your online account or contacting your eTag provider directly. 

Selling a Registered vs Unregistered Car: How Do They Differ

Simply put, a car with valid registration in NSW can legally be driven, whereas an unregistered one cannot.

If you are selling a vehicle with valid registration, it's essential to transfer the registration within 14 days of the sale; this includes cancelling the existing registration and transferring it to the new owner. Failure to do so results in both parties being liable for any fines associated with an unlawfully–operated vehicle.

Alternatively, if you're selling an unregistered vehicle, there is no need to transfer the registration. Instead, provide your buyer with a valid Roadworthy Certificate or Safety and Identity Inspection Certificate plus a receipt for the purchase and sale of the vehicle.

Steps to Selling a Used Car in New South Wales

Having reviewed the necessary paperwork, let's outline the process of selling a used vehicle in New South Wales. 

  • Prep Your Car

Ensure your car is in peak condition before you list it for sale, and give buyers the confidence that they are getting a dependable vehicle at a fair price. Investing time in detailing, repairs, and maintenance will pay off when selling used cars in NSW. 

  • List Your Vehicle

Once you've established your car's value and prepared it for sale, the next step is to list it so potential buyers can easily find it. One of the most convenient ways to do this is through OnlyCars – a platform that connects you with local prospects. When creating your listing, make sure to include the following:

  • Valuable features and specifications 
  • Photos of the car from different angles 
  • Full disclosure of any existing damage, repairs or modifications done to the vehicle.

To attract buyers and ensure a smooth process, price the car realistically. 

  • Negotiate with Buyers

Once you have kindled interest from prospective purchasers, it's time to begin haggling for a mutually beneficial sale price. Ensure all required documents are available and inform your buyer of any contingencies associated with the transaction before signing off on the agreement.

Once you agree on a sale price and the buyer has paid in full, you must provide all necessary paperwork and certifications, including insurance coverage up to the date of transfer. 


Advertising a pre–owned vehicle in New South Wales can be tricky. However, by following these steps and adhering to the applicable laws can reduce some of the stress involved. Maximise your reach by listing on OnlyCars and price your car fairly for an effortless sale. With this guide as your reference, selling used cars in NSW is easy!
