Evidence and Records for CTP Claims Involving Vehicle Modifications in NSW

This article explains the evidence required to support CTP claims involving vehicle modifications in NSW, including medical records, modification documentation, and SIRA's requirements. It outlines practical steps to preserve records and highlights time limits for benefits.

Current as at 15 October 2026

If you've suffered a disabling injury in a motor vehicle accident and need vehicle modifications like hand controls or mobility aids, you must document your injuries and modifications carefully. Under NSW CTP rules, evidence of your injury's impact on daily life and the necessity of modifications is critical to support your claim. This article explains what records to keep, how SIRA's guidelines apply, and when to seek legal advice.

What Evidence Proves Vehicle Modifications in a CTP Claim?

To establish that vehicle modifications are necessary due to a disabling injury, you must provide:

  • Medical evidence showing a permanent impairment or neurological injury (e.g., spinal nerve-root damage, radiculopathy) that affects mobility.
  • Documentation of modifications like hand controls, ramps, or adaptive devices, including receipts, quotes, and installation records.
  • Evidence of functional limitations such as medical reports detailing reduced mobility, balance issues, or chronic pain.
  • Witness statements or statements from healthcare professionals confirming the modifications' necessity.

SIRA's guidelines require claimants to demonstrate a direct link between the injury and the modifications. For example, a spinal injury causing radiculopathy (as defined in the Motor Accident Guidelines) may justify hand controls, while a soft-tissue injury without neurological signs may not.

Practical Steps to Document Vehicle Modifications

  1. Keep all medical records related to your injury, including scans, specialist reports, and notes from physiotherapists or occupational therapists.
  2. Record the cost and details of modifications. Include invoices, quotes, and any correspondence with suppliers or installers.
  3. Maintain a journal of how your injury affects daily activities, such as difficulty driving, walking, or performing household tasks.
  4. Preserve accident details like police reports, witness statements, and photos of the vehicle damage.
  5. Notify your insurer promptly about the modifications and their cost, as delays may affect benefit eligibility.

Time Limits and Dispute Resolution

You have 52 weeks from the accident date to claim weekly income benefits for threshold injuries. After this period, benefits may stop unless you have a whole-person impairment rating of 10% or more. If your claim is disputed, SIRA's review process allows you to submit additional evidence, such as updated medical opinions or cost estimates.

When to Seek Legal Advice

If your injury involves complex neurological signs, such as spinal nerve-root damage with neurological symptoms, or if your claim is rejected, consult a solicitor. Legal advice can help you navigate SIRA's requirements and ensure all evidence is properly submitted.
