Is it bad to leave your car parked for weeks at a time?
Leaving your car parked for weeks affects more than just the battery. Here's what actually happens and how long each problem takes to start.


Handing over the keys feels like the finish line. It isn't quite. There are several steps you need to take after a private car sale to protect yourself legally and financially. Most of them take only a few minutes. Skip them and you can spend weeks dealing with the consequences.
This is the most important step and the one sellers most often forget. In New South Wales, you must lodge a Notice of Disposal (NoD) with Service NSW within 14 days of the sale. Other states have their own equivalent notification processes, most with similarly short deadlines.
The NoD records the sale date and the buyer's details, and removes your name from the vehicle's operator record. Without it, any fines, toll notices, or parking infringements generated by the new owner can land with you. In NSW, lodge it at service.nsw.gov.au. It takes a few minutes and is free.
If you sold to Carma, this step is managed as part of the process. You don't need to lodge it separately.
Once the car is sold, your insurance policy on that vehicle serves no purpose. Contact your insurer the same day as the sale and cancel the policy. Most insurers will refund unused premium for the remaining period, though some policies have cancellation fees.
If you're planning to buy another car soon, ask your insurer whether your policy can be transferred or suspended rather than cancelled outright. Some policies allow a brief suspension between vehicles without losing your no-claim bonus history, which can save you money when the next policy starts. The exact process varies by insurer, so confirm the options before you cancel anything.
In some states, you may be entitled to a refund on unused registration if you cancel the registration at the time of sale rather than leaving it in place for the buyer to transfer. This varies by state and by how much registration is remaining.
In NSW, you can apply for a rego refund if you cancel the registration yourself. The refund is calculated on the remaining full months, not the exact remaining days. If the sale price included the remaining rego as part of the agreed amount (as many private sales do, since buyers expect to inherit the current registration), this step may not apply. But if you're cancelling the registration rather than transferring it to the buyer, it is worth checking the refund entitlement before you do so.
If your car had personalised plates, those belong to you, not to the vehicle. Remove them before handing over the car and have standard plates fitted. In NSW, you can apply to keep personalised plates in storage through Service NSW. Failing to remove them means you lose them to the buyer by default.

If there was a car loan on the vehicle, confirm with your lender that the payout has been received and the account is closed. This usually happens within one to two business days of settlement. Once it's confirmed, ask your lender for written confirmation that the loan has been settled and the security interest on the PPSR has been discharged.
Keep this confirmation. If any query about the vehicle's PPSR status arises later, this document is your evidence that the encumbrance was cleared at the time of sale.
Electronic toll accounts in Australia (such as E-Toll in NSW or e-TAG accounts in other states) are associated with the vehicle's licence plate. After selling the car, remove the old plate from your toll account to prevent being charged for the new owner's tolls. You may also need to collect your transponder if it was a physical tag rather than a sticker.
Most state toll providers allow you to manage your registered vehicles through their online account portal. Log in, remove the sold vehicle's plate, and check that no outstanding charges are pending. If the new owner begins using toll roads before you've removed the plate, those charges may default to your account until the plate is de-registered from it.
In a private sale, confirm that the payment has cleared properly before you consider the transaction complete. A bank cheque is generally safe, but the safest method is a direct bank transfer from the buyer to your account, with confirmation from your bank that the funds have settled. Cash sales carry their own risks and should be handled at a bank or with a third party present.
If any part of the payment arrangement was unusual or the buyer has been slow to send funds, follow up promptly in writing so you have a record of the communication. Be cautious of buyers who ask for delayed payment or suggest alternative payment methods. Cleared funds in your account at the time of handover is the cleanest and safest outcome. Never hand over the car if you have any doubt about whether payment has actually settled.
If you've sold and you're looking for a replacement, browse used cars at Carma. Every car has been through the Carma standard: an NRMA-verified inspection and reconditioning process, with transparent pricing and a 7-day return policy. If you haven't sold yet and are still weighing up your options, get a valuation from Carma first.
