How Insurers Assess Liability for Transitional Claims under the MAI Act in Greater Sydney

A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).

If you've been involved in a motor accident in Greater Sydney and your claim spans the change from the old Motor Accidents Compensation Act 1999 (MACA) to the new Motor Accident Injuries Act 2017 (MAIA), you may be wondering how insurers assess liability. This article explains the legal framework insurers use to evaluate transitional claims, focusing on the practical steps and evidence that matter.

The NSW CTP Rules Behind Transitional Claims

Under the MAI Act, claims that began before 1 December 2017 are considered transitional claims. These claims are governed by a mix of the old MACA and the new MAIA. Insurers assess liability by looking at the date of the accident, the nature of the injuries, and the evidence available to determine whether the claim falls under the old or new scheme.

The key factor is the date of the accident. If the accident occurred on or after 1 December 2017, the claim is governed by the MAIA. If it occurred before that date, the claim is under the MACA. However, if the claim was started before 1 December 2017 but the accident occurred after that date, the claim is considered a transitional claim and is assessed under the MAIA.

Practical Steps and Evidence That Usually Matter

When assessing liability for transitional claims, insurers look at several factors, including:

  • The date of the accident - This determines which scheme applies.
  • The nature of the injuries - Whether the injuries fall under the threshold injury definition or require a whole person impairment assessment.
  • The evidence available - This includes medical records, accident reports, witness statements, and any correspondence with the insurer.
  • The claimant’s history - Whether the claim was started before or after the scheme change.

It’s important to keep detailed records of your injuries, treatment, and any communication with the insurer. This evidence helps insurers determine the correct scheme to apply and the appropriate benefits or damages.

Time Limits, Disputes and When to Seek Advice

Transitional claims are subject to the same time limits as other CTP claims. Under the MAIA, you have a maximum of 3 years from the date of the accident to make a claim. If the claim was started under the MACA, the time limit may be different, depending on when the claim was made.

If you believe the insurer has assessed your claim incorrectly, you may need to dispute their decision. This could involve providing additional evidence or seeking legal advice. It’s important to act quickly, as delays can affect your ability to challenge the insurer’s assessment.

Common Pitfalls to Avoid

When dealing with transitional claims, there are a few common pitfalls to avoid:

  • Not understanding the date of the accident - This can lead to confusion about which scheme applies.
  • Not keeping detailed records - Without proper records, it may be difficult to prove the claim.
  • Not seeking advice early - Delaying can result in missed opportunities to challenge the insurer’s assessment.

If you’re unsure about your claim or the insurer’s assessment, it’s important to seek legal advice. A solicitor can help you understand your options and ensure your claim is assessed correctly under the right scheme.

When to Seek Legal Advice

If you’re involved in a transitional claim, it’s important to understand the legal framework and the steps you need to take. While this article provides general information, it’s not a substitute for legal advice. Every claim is unique, and the outcome depends on the facts of your case.
