What Evidence to Keep for Partial Fault CTP Claims in NSW

Retaining the right evidence is crucial for partial fault CTP claims in NSW. This guide explains what records to keep, how to organize them, and the legal considerations for shared liability cases. Time limits and disputes may affect your claim, so seek advice if you're unsure about your next steps.

Current as at 8 November 2026

If you're involved in a motor accident where both parties share responsibility, retaining the right evidence is critical to support your claim under NSW's Compulsory Third Party (CTP) scheme. Partial fault claims require careful documentation to prove the accident's circumstances, your injuries, and the other party's contribution to the crash. This guide explains what evidence matters, how to organize it, and the legal considerations for shared liability cases in Greater Sydney.

The NSW CTP Rules Behind Partial Fault Claims

Under the Motor Accident Injuries Act 2017 (MAIA), CTP claims in NSW are governed by a no-fault system. This means you can claim compensation even if you were partially at fault, provided the accident involved a registered motor vehicle. However, the amount of compensation may depend on the degree of fault attributed to all parties. While the CTP scheme does not directly address fault allocation, the evidence you provide will help determine the proportion of liability and the scope of your claim.

The key is to demonstrate that the accident occurred and that your injuries were caused by the incident. Fault is not the primary focus of CTP claims, but it can influence the outcome if the claimant's own actions contributed to the crash. For example, if you were speeding and the other driver ran a stop sign, both parties may share liability. The evidence you collect will help establish the facts of the accident and support your right to claim.

Practical Steps and Evidence That Usually Matter

To build a strong case, you should retain the following types of evidence:

  • Medical records: Document all injuries, treatments, and medical opinions. This includes diagnostic reports, specialist notes, and records of ongoing care. For threshold injuries (soft tissue damage), ensure you have evidence of neurological signs or spinal nerve-root injuries as defined by the Motor Accident Guidelines.
  • Accident reports: Obtain a police report if an officer attended the scene. This document provides an official account of the incident, including vehicle details, witness statements, and any traffic violations.
  • Witness statements: Statements from people who saw the accident can help establish the sequence of events. Even if a witness is not a police officer, their account can support your version of the incident.
  • Photographs and videos: Take pictures of the vehicles, the scene, and any visible injuries. Avoid using phone footage unless it captures the accident itself, as it may be considered evidence of fault.
  • Vehicle and insurance details: Keep copies of registration documents, insurance policies, and any correspondence with the other party's insurer. This information helps identify the parties involved and confirms that the accident was covered by CTP insurance.
  • Income and expenses: If you've lost income due to the accident or incurred medical costs, retain payslips, bank statements, and receipts. This evidence supports claims for weekly income payments or treatment and care benefits.

Organizing these records in chronological order and linking them to specific events will help you present a clear narrative of the accident and its impact. For example, if you were injured in a collision where both parties were at fault, your medical records and witness statements will be essential to show that the injuries were caused by the incident.

Time Limits, Disputes and When to Seek Advice

CTP claims in NSW have strict time limits. You must notify the relevant insurer within 90 days of the accident, and the claim itself must be submitted within 12 months. If you fail to meet these deadlines, you may lose your right to claim compensation. While the CTP scheme does not directly address disputes over fault, the evidence you provide will be crucial if the insurer challenges the validity of your claim.

If the insurer disputes the extent of your injuries or the contribution of the other party to the accident, you may need to seek independent medical opinions or legal advice. The CTP scheme does not cover disputes over fault, but it does cover the cost of medical treatment and income loss. If your claim is rejected, you may need to pursue a separate legal action to address the issue of liability.

In cases where the accident involved multiple parties or complex circumstances, it's advisable to consult a legal professional. While the CTP scheme provides a no-fault pathway, the evidence you retain will determine whether you can claim compensation for your injuries. If you're unsure about the strength of your claim or the steps to take, completing the quick, no obligation enquiry form can help you request contact about your circumstances.

A Hypothetical Example

Consider a scenario where two cars collide at an intersection. One driver was speeding, while the other ran a stop sign. Both parties contributed to the accident, but the speeding driver's actions were the primary cause. In this case, the claimant would need to provide evidence such as:

  • A police report confirming the stop sign was run
  • Witness statements supporting the speeding claim
  • Medical records showing injuries caused by the collision

This evidence would help establish the facts of the accident and support the claimant's right to seek compensation. While the CTP scheme does not directly address fault, the evidence will help determine the proportion of liability and the scope of the claim.

Next Steps

Retaining the right evidence is essential to support your CTP claim, especially in cases of partial fault. While the CTP scheme provides a no-fault pathway, the evidence you collect will determine whether you can claim compensation for your injuries. If you're unsure about the strength of your claim or the steps to take, completing the quick, no obligation enquiry form can help you request contact about your circumstances.

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
