Common Mistakes to Avoid in CTP Claims Involving Vehicle Modifications

If you've suffered a disabling injury in a motor vehicle accident and need vehicle modifications to regain mobility or independence, you may be eligible for benefits under NSW’s Compulsory Third Party (CTP) scheme. However, many claimants make errors that could harm their case. This article explains the most common mistakes to avoid when dealing with CTP claims involving vehicle modifications, including how to prove your need for modifications and what evidence matters.

Key NSW CTP Rules for Vehicle Modifications

Under the Motor Accident Injuries Act 2017 (MAIA), vehicle modifications are considered when assessing claims for treatment and care benefits, weekly income payments, or lifetime care. However, the CTP scheme has strict rules about what qualifies as a 'necessary modification' under the Motor Accident Guidelines. For example:

  • Modifications must be medically necessary to address your injury or disability.
  • You must provide evidence that the modification was recommended by a medical practitioner.
  • The modification must be directly related to your injury, not a general mobility aid.

A common mistake is assuming that any mobility aid qualifies. For instance, if you need hand controls but the insurer disputes their necessity, you’ll need medical records proving the modification was recommended for your specific injury.

Practical Steps and Evidence to Gather

To support your claim, you must document:

  • Medical records showing the injury’s impact on mobility and the need for modifications.
  • Proof of the modification (e.g., receipts, photos, or a report from the modification provider).
  • Communication with your insurer about the modification’s necessity.

Avoid these errors:

  • Failing to document the modification process.
  • Not seeking medical advice before making modifications.
  • Assuming the insurer will automatically approve all modifications.

Time Limits, Disputes and When to Seek Advice

CTP claims must be made within 52 weeks of the accident if you’re seeking weekly income payments or treatment benefits. If your claim involves disputes over the modification’s necessity, you may need to:

  • Request a review of your claim.
  • Seek independent medical advice.
  • Consider mediation or legal assistance if the insurer refuses to pay.

If you’re unsure whether your modification qualifies, contact the insurer immediately. Delays can lead to lost benefits or disputes.

Final Steps

CTP claims involving vehicle modifications require careful documentation and understanding of the scheme’s rules. Avoid common mistakes like poor evidence, delays, or assuming modifications are automatically approved.
