Private sale fine print: what warranty you get, the receipt you need, and how to transfer the rego
Most buyers think a faulty private purchase means a refund, and most sellers think “as is” wipes the slate clean. The truth sits in between, and the paperwork is what makes it hold. The law is drier than the car, but it is the part that bites.
Private sale, not a shop sale
The consumer guarantees under Australian Consumer Law attach to goods sold by a business. A genuine one-off sale between two private people is different. If the item fails a month later, there is no automatic refund, repair or swap-back, because there is no business holding the guarantee. That is the first thing to understand about consumer rights on a private sale in Australia: you are buying the item as it stands.
The one real exception is a seller who lies. If they describe the car falsely, or hide a known fault, they can still be held to account. But chasing a private seller is harder than walking back into a shop, which is why the checking happens before the money moves, not after.
Is there a warranty on a private sale?
No automatic statutory warranty comes with a private sale, the way state motor car trader laws give a warranty on a dealer sale. A warranty exists only when a seller puts one in writing, and then it becomes a binding term of the contract. If the ad or a message promises “three months warranty”, get that in writing before you pay. A verbal promise from a private seller is worth very little once the car is sitting in your driveway.
The receipt that protects both of you
A written receipt is your proof, so make it count. For a private car sale receipt to do its job, it should list the date, both full names and addresses, and the item. For a car that means the make, model, VIN and engine number, the odometer reading, the price and the words “sold as is”. Both parties sign, and both keep a copy. A photo of the signed receipt on both phones costs nothing and settles most arguments before they start.
For a car, this receipt sits alongside the state’s own transfer paperwork. It does not replace it.
Transferring a car: rego, plates and who tells who
Selling a car privately in Australia comes with a transfer step that is easy to forget. The buyer has to transfer the registration into their own name within the state’s timeframe, commonly about 14 days, and each state runs its own online process. The seller lodges a notice of disposal online at the same time, so fines, tolls and demerits stop following the car.
If the car cannot be registered as is, it may need an unregistered vehicle permit or an inspection before it can be transferred, so factor that into the price before you agree on one. And do the PPSR check before you pay, so you are not buying a car that still owes money to a finance company.
Faulty goods after the sale
“Sold as is” is real, but it is not a licence to mislead. If the seller described the item falsely, or hid a known fault, you can pursue them through your state’s small claims tribunal. The paperwork and the messages are your evidence, which is why the receipt and the wording of the ad matter.
Set your expectations honestly. The tribunal route exists, but it is slow, and it works best when you have the documents on your side. That is the quiet argument for doing the checking before the sale instead of relying on a fight afterwards.
Do you owe tax on what you sell?
For most people, no. Selling your own secondhand car or household goods is generally not taxable, and a private car is exempt from capital gains tax. The line moves if you make a habit of buying things to flip for a profit. At that point it can start to look like a business, and different tax rules and GST can apply. If you are a regular flipper, see a tax professional. For a one-off clear-out of your own things, it is not something to lose sleep over.
Paperwork is your protection
No automatic warranty. A written receipt is your proof. The rego transfer is not optional. Those three lines carry most of the risk out of a private sale. The paperwork is not exciting, but it is the difference between a deal and a dispute.
