MAI Act Transitional Claims: Injury Documentation Checklist for NSW

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

If you're claiming compensation under the Motor Accident Injuries Act (MAI) Act for an injury caused by a motor vehicle accident in New South Wales, you need to understand how to document your claim. Transitional claims cover accidents occurring before 1 December 2017, when the old Motor Accidents Compensation Act (MACA) was replaced by the MAI Act. This checklist explains the evidence required to support your claim under the transitional provisions.

What Evidence is Needed for Transitional Claims?

Under the MAI Act, claimants must provide documentation to prove their injuries and entitlements. Key evidence includes:

  • Medical records: Detailed reports from doctors confirming your injuries, treatment received, and how the accident affected your health.
  • Accident report: Police or insurance company records detailing the incident, including dates, times, and vehicle details.
  • Witness statements: Statements from people who saw the accident or can confirm its circumstances.
  • Photographs: Images of injuries, vehicle damage, or accident scene.
  • Income records: Proof of lost wages or reduced earning capacity if your injury impacted your ability to work.
  • Insurer correspondence: Copies of all communications with the at-fault driver’s insurance company.

The New South Wales Motor Accident Claims Authority (SIRA) provides guidelines on what to include in claims. For transitional claims, you must also demonstrate that your injuries fall within the MAI Act’s definition of a 'threshold injury' or higher, as outlined in the Motor Accident Guidelines.

How Does Transitional Documentation Differ from Standard CTP Claims?

Transitional claims under the MAI Act have specific rules. For example, weekly income payments and treatment benefits are limited to 52 weeks if your injuries are classified as 'threshold injuries' only. This differs from standard CTP claims, where benefits may continue beyond 52 weeks if the injury is more severe.

Under the MAI Act, claims for 'threshold injuries' must include evidence that the injury meets the spinal nerve-root qualification. This means the injury must produce neurological signs beyond radiculopathy, as defined in the Motor Accident Guidelines. If your injury does not meet this threshold, you may be eligible for additional compensation.

When to Seek Legal Advice

If your claim involves complex documentation, such as overlapping workers’ compensation claims or disputes over fault, it’s important to seek legal advice. Transitional claims can be particularly sensitive due to the transition from MACA to MAIA, and errors in documentation may affect your entitlements.

Example: Transitional Claim Documentation in Practice

Consider a claimant who was injured in a 2016 car accident. Their medical records show soft tissue injuries meeting the threshold definition, but they also have chronic back pain requiring ongoing treatment. Under the MAI Act, they must provide evidence of both the threshold injury and the additional chronic condition to qualify for long-term benefits. This requires detailed medical documentation and a clear explanation of how the injuries impact daily life.
