Identifying the Correct CTP Insurer for Your Claim
To lodge a CTP claim, you must identify the insurer of the vehicle at fault. In NSW, there are several licensed insurers (like NRMA, GIO, Allianz, QBE). If you were at fault, or it was a single-vehicle accident, you generally lodge with your own vehicle’s insurer. General information only.

Top questions answered
How do I find out which company insures the at-fault vehicle?
You can use the "Free Registration Check" tool on the Service NSW website (https://check-registration.service.nsw.gov.au/frc?isLoginRequired=true). You will need the registration plate number of the vehicle and the date of the accident.
What if the at-fault vehicle is from interstate?
If the at-fault vehicle is interstate-registered, statutory benefits may be handled via the Nominal Defendant pathway in NSW, while common law damages may proceed against the interstate insurer. Get advice early because pathway and timing issues can be technical.
What if I was at fault for the accident?
In NSW, you still lodge your claim with your own CTP insurer. The current scheme provides benefits for both at-fault and not-at-fault drivers for at least the first 52 weeks (subject to threshold injury and degree of fault rules later).

Quick answer: who do I claim with?
If the at-fault vehicle is NSW-registered: identify that vehicle's CTP insurer using the Service NSW registration check and claim there.
If you were at fault / single-vehicle accident: usually claim statutory benefits through your own vehicle's CTP insurer.
If the vehicle is unidentified, unregistered, or hit-and-run: urgently assess the Nominal Defendant pathway and keep due-inquiry evidence.
If the vehicle is interstate-registered: statutory benefits and common law damages can run on different insurer pathways, so map both tracks early.
For NSW-Registered Vehicles
If the vehicle at fault has NSW registration plates, identifying the insurer is straightforward:
- Visit the Service NSW Free Registration Check.
- Enter the vehicle registration number (the license plate).
- Enter the date of the accident.
The result will show the CTP insurer for that vehicle.
Practical tip: it is usually best to have a specialist lawyer help prepare your Application for Personal Injury Benefits so injuries and entitlements are not missed. Contact us before you lodge if possible.
Unidentified or Unregistered Vehicles
If the other driver left the scene without providing details (hit-and-run) or if the vehicle was unregistered:
- You may be able to lodge a claim against the Nominal Defendant.
- The Nominal Defendant is a statutory body that acts as an insurer in these specific cases.
- Strict "due inquiry and search" requirements apply—you must show you tried to find the vehicle.

Interstate-registered at-fault vehicles
If the at-fault vehicle is registered interstate, the pathway can split:
- Statutory benefits: may be managed through the Nominal Defendant pathway in NSW.
- Common law damages: may be pursued against the interstate insurer.
Because this can involve two tracks, get advice early on evidence, limitation periods, and the order of steps. See Interstate insurer claim pathway.
If You’re Having Trouble
Finding the right insurer is the most common reason for delays in the first 28 days. If you cannot identify the other vehicle, or the insurer search returns no results, contact us immediately. We can help track down the correct entity so your claim is not timed out.

- What if an insurer says I have claimed against the wrong entity because ownership changed near the accident date?
- Ask for written reasons and the exact policy period they rely on. Then preserve both pathways in parallel: lodge with the insurer shown on the registration check for the accident date, notify the alternate insurer if transfer timing is disputed, and keep RMS transfer records, police facts, and photos in one chronology. This reduces the risk of limitation damage while the identity dispute is sorted.
- What if I am close to the 28-day deadline but insurer identity is still disputed?
- Do not wait for insurers to sort it out privately. Lodge promptly on the best available accident-date evidence, send a short chronology and supporting documents, and put any alternate insurer on notice the same day. This protects timing while insurer identity is resolved.
