When a NSW CTP insurer changes assessors, claimants must provide specific documentation to support their injury claims. The Motor Accident Injuries Act 2017 and SIRA guidelines outline the evidence required to ensure claims meet legal standards. This checklist explains what documentation is needed, how to prepare it, and when to seek legal advice.

NSW CTP Rules Behind Assessor Changes

Under the Motor Accident Injuries Act 2017, CTP insurers must assess claims based on SIRA's guidelines. If an insurer replaces its assessor, the claimant must submit updated evidence to support their injury documentation. The legal framework requires claimants to demonstrate that their injuries meet the 'threshold injury' criteria or qualify for damages under the Act. SIRA's guidelines clarify that documentation must show a direct link between the accident and the injury, including medical evidence and accident details.

Key Documentation for Assessor Changes

Claimants must prepare the following evidence when an assessor change occurs:

  • Medical records: Detailed reports from healthcare providers confirming the injury's nature, date of treatment, and prognosis.
  • Accident reports: Official documents from police, hospitals, or witnesses describing the incident.
  • Witness statements: Accounts from individuals who observed the accident.
  • Photographs: Images of the accident scene, vehicle damage, or injury-related conditions.
  • Income records: Proof of lost wages or reduced earning capacity.
  • Insurer correspondence: Emails or letters showing communication with the insurer.

SIRA's guidelines emphasize that incomplete documentation may delay claims or result in disputes. For example, a claimant with a soft tissue injury must provide medical evidence showing spinal nerve-root damage or radiculopathy, as outlined in the Motor Accident Guidelines.

Practical Steps and Time Limits

Claimants should act promptly to ensure documentation is complete before the 52-week statutory benefits period expires. Under s 4.4 of the Motor Accident Injuries Act 2017, weekly benefits and treatment payments are limited after 52 weeks if only threshold injuries are involved. If a claimant disputes the assessor's findings, they can request a review through SIRA's internal process or seek legal advice.

A hypothetical example: A cyclist injured in a car park must provide medical records showing a threshold injury, accident reports from the police, and photographs of the collision. If the insurer replaces the assessor, the claimant must submit these documents again to support their claim.

When to Seek Legal Advice

Disputes over documentation can arise if the insurer challenges the injury's severity or the link to the accident. Legal professionals can help claimants navigate SIRA's requirements, ensure compliance with the 52-week rule, and challenge unfair assessments. Time limits for disputing decisions are governed by the NSW Civil and Administrative Tribunal (NCAT) rules.
