Transferring CTP When Selling a Car

If you are asking do I need to transfer my CTP when I sell my car, the short answer for a Perth WA sale is: no, you do not need to manually transfer it in a normal private sale. In Western Australia, CTP insurance (officially called motor injury insurance) is bundled into your vehicle registration and is attached to the vehicle itself, so it generally moves with the car when the change of ownership paperwork lands with the Department of Transport.

What the seller does still matters, though. Get the timing wrong and you can end up wearing toll notices, speed-camera infringements, or worse, an injury claim conversation for an accident that happened after you had already handed the keys over. At Sell My Car Pro, as a Licensed WA Motor Vehicle Dealer and Motor Trade Association member, we walk Perth sellers through this every week so the paperwork lines up cleanly the first time.

What CTP Insurance Actually Covers

Compulsory third-party insurance is the legal floor. It exists to cover personal injury to other people if your motor vehicle is involved in a crash. It does not cover damage to other cars, fences, lamp posts, your own car, or your own injuries in many circumstances.

In Western Australia, motor injury insurance is administered by the Insurance Commission of Western Australia (ICWA) and is automatically included in your annual vehicle licence fee. That is structurally different from how other states handle it (Queensland and New South Wales drivers shop between multiple CTP “Green Slip” insurers, while WA, Victoria, the Northern Territory, and Tasmania run a single statutory model through a government-backed insurer).

The takeaway: CTP is attached to the vehicle and continues with the registration. Your comprehensive or third-party property cover is attached to you, and you have to manage that one separately. We cover the comprehensive side in detail in our companion piece on what happens to insurance when you sell a car.

How CTP Works In Western Australia In Practice

Open your most recent rego renewal notice and you will see the breakdown. The motor injury insurance premium sits as a separate line item alongside the licence fee, recording fee, and any plate fees. For the current schedule, the ICWA premium for a standard private passenger vehicle (Class 1A) is $504.70 per year as of 1 July 2025 (rate inclusive of GST and duty), with motorcycles, light commercials, and heavy vehicles sitting on different rate scales.

You do not phone an insurer when you sell. You do not fill in a CTP transfer form. The premium follows the vehicle through to the next registered owner, and the renewal date stays the same.

What You Must Do As The Seller To Stay Protected

Even with CTP handled automatically, the paperwork side of the sale has to be tight. We see three habits separate clean sales from messy ones.

Lodge The Change Of Ownership Inside The 7-Day Window

In WA, the seller’s Notice of Disposal must be lodged with the Department of Transport within 7 days of the sale. You can do this through DoTDirect online, in person at a DoT Driver and Vehicle Services centre, or by posting in a completed MR9 vehicle change of ownership form. The buyer has the same window to lodge their side, but you cannot rely on them to do it on time.

A Mount Lawley seller we worked with last year sold a 2017 Hyundai i30 to a backpacker heading east through the Nullarbor. The buyer promised to transfer the rego “next week” once he reached Adelaide, then disappeared. Three months later, the seller had a stack of speed-camera notices from the Eyre Highway sitting on his kitchen bench, all addressed to him because the rego was still in his name. The fines were eventually withdrawn after he produced the dated Notice of Disposal he had filed within 48 hours of the sale, but the admin chase cost him six weeks of phone calls. The lesson he passed on to us, and we now pass on to every seller: lodge your side of the transfer the same day the keys leave your hand, not next week.

For the full walk-through of the WA paperwork sequence, including the MR9, Notice of Disposal, and seller protection, our guide on how to sell a car in Western Australia covers it step by step.

Write A Receipt That Actually Holds Up

A handwritten sticky note will not save you in a dispute. Create a receipt that includes the sale date and time, full names and current addresses of both parties, the buyer’s driver licence number, the vehicle identification number (VIN), the rego plate, the odometer reading, the agreed sale price, and signatures from both sides. Keep a copy yourself and email a scan to your own address as a timestamped backup.

A Doubleview seller we helped a few years back sold a 2014 Ford Focus to a buyer from Mandurah who turned up with cash and a confident handshake. No receipt was written. Eight weeks later, the seller received a courtesy call from WA Police asking him to come in and discuss a hit-and-run his “vehicle” had been involved in along Stirling Highway. The car had been re-sold twice in the interim, the second buyer never registered, and the trail led back to the registered owner on paper. Two days of statements and a written receipt found buried in a Gmail thread eventually cleared things up. He never sold a car without a proper receipt again.

If you have lost your rego papers ahead of the sale, our explainer on do you need rego papers to sell a car in Perth covers how to handle that without delaying the transfer.

Handle Test Drives With Eyes Open

There is no legal requirement to hold comprehensive insurance to sell a private car in WA, but letting a stranger steer your car without cover is a financial gamble. CTP will deal with the personal injury side if something goes wrong, but it will not pay to fix your panels or replace someone else’s bumper. The risk is yours until the buyer takes ownership.

Practical habits that lower the risk:

• Sight the buyer’s physical driver licence and confirm it is current and unrestricted
• Keep test drives short, on roads you know, and during daylight
• Sit in the passenger seat and keep the spare key in your pocket
• Hold off cancelling your comprehensive policy until after the sale has settled

A Carine couple we sold a vehicle to last year had a near-miss go the other way. Their daughter listed her 2019 Mazda 2 privately, accepted a test drive with a buyer who flashed a Victorian driver licence (later turned out to be a photoshopped scan), and watched him drive off without coming back. The car was recovered three days later in Two Rocks, but only because she had documented everything (his real photo from the listing reply, the dodgy licence scan, the test drive request texts). CTP would have done nothing for her in that scenario. The verification habit is what saved the car.

Plates, Cancelling Rego, And Refunds

For a standard WA-to-WA sale, the plates stay on the car. You leave them attached, complete the transfer, and the rego rolls across to the new owner with whatever portion of the year remains.

If you are selling interstate, the picture shifts. WA registration cannot be held by a non-WA resident, so the typical sequence is: cancel the WA licence with DoT, surrender the plates at a Driver and Vehicle Services centre (or a regional licensing centre such as Mandurah, Joondalup, or Cannington), then deliver the unregistered vehicle to the buyer. The buyer arranges interstate transport (usually on a tilt-tray or transporter) and re-registers in their home state.

When you cancel rego, you may be eligible for a pro-rata refund on the unused portion of the licence fee and the motor injury insurance component, processed by DoT and ICWA respectively. Refund timing is typically two to four weeks, and the refund goes to the registered owner. Personalised plates can be retained at this point if you want to put them on a new vehicle later.

If you are keeping personalised plates for your next car, swap them off before the buyer takes possession at a DoT centre rather than trying to unwind it after the sale.

Quick State Comparison Notes

Because Perth sellers occasionally end up dealing with interstate buyers or sellers, it helps to know how the rules shift over the border.

Queensland requires a safety certificate (also known as a roadworthy) before transferring a registered vehicle in most cases. New South Wales calls it a pink slip (an eSafety inspection) on most registration transfers and the rego itself sits as a separate line from the Green Slip (CTP). Victoria requires a Roadworthy Certificate (RWC) issued within the past 30 days for most private sales. South Australia and the Australian Capital Territory have their own variations.

Western Australia is unusual in that we do not require a roadworthy certificate for most private sales, but we do require accurate disclosure and clean paperwork. That makes WA simpler in theory and trickier in practice, because the burden of proving the sale was clean sits on the seller’s documentation.

If timing matters to your sale, our analysis on when is the best time to sell your car in Perth lays out the strongest months for private sale demand in WA, including the school-holiday and tax-return spikes.

Where Sell My Car Pro Fits Into This

We are not in the business of complicating a clean sale. Where we add value is in the sequencing and the paperwork: making sure the MR9 is correct, the Notice of Disposal is filed, the rego status is verified, and the buyer leaves with the right documents so the transfer actually lands rather than getting stuck in a backlog.

If you would rather not navigate the test drives, the suburban tyre-kickers, and the buyer who promises to transfer “next week”, a sale through us takes those moving parts off your plate. Our car trade in Perth page covers how the inspection and offer process runs, and the most profitable way to sell your car walks through the trade-off between private listing, trade-in, and a direct car buyer.

Frequently Asked Questions

Do I Need To Call My CTP Insurer After I Sell?

In WA, generally no, because the motor injury insurance premium is bundled into the vehicle licence and follows the registration to the next owner. Your job is to lodge the Notice of Disposal with the Department of Transport and update or cancel your own separate comprehensive policy.

Does CTP Automatically Stay With The Vehicle?

For a normal WA private sale, yes. The CTP component continues with the registration, which is why you do not see a separate “CTP transfer” step in the WA process.

What If The Buyer Has Not Transferred Rego Yet?

This is where sellers get caught out. Lodge your own seller-side Notice of Disposal inside the 7-day window using DoTDirect or an MR9 at a DoT centre, and keep dated proof. If the buyer delays and something happens (a fine, an infringement, an accident), your dated notice is the document that protects you.

Do I Get A Refund For Unused CTP In WA?

If the car stays registered and the rego is transferred, no, because the registration continues with the vehicle. If you cancel the licence (typical for an interstate sale or scrapping the car), you may be eligible for a pro-rata refund covering the unused portion of the licence fee and the motor injury insurance component.

Is CTP The Same As Comprehensive Insurance?

No, and this catches plenty of sellers out. CTP only covers personal injury to other people. It does not cover damage to your car, the other car, property, theft, fire, or storm. Comprehensive cover is the policy that handles that, and it does not transfer to the buyer when you sell.

Can I Sell A Car With Cancelled Rego Or No CTP In WA?

Yes, you can sell an unregistered vehicle in WA, but you must clearly disclose it as unregistered and the buyer cannot drive it on a public road without a permit. The buyer will need to arrange transport (a tow truck, trailer, or DoT-issued unregistered vehicle permit) and re-register the car in their name with a valid CTP premium before driving.

Conclusion And Next Steps

So, do I need to transfer my CTP when I sell my car in Western Australia? In a typical WA sale, no, because the motor injury insurance premium is attached to the vehicle registration and continues with the car. What matters is the speed and accuracy of the change-of-ownership paperwork, the receipt you keep on file, and the discipline you apply to test drives and your own comprehensive cover.
