CTP Insurer Time Limits for Changing Assessors in NSW

If you're involved in a motor accident claim in New South Wales and your insurer wants to change the assessor or case manager, you need to understand the legal time limits. Under NSW law, insurers must act within specific deadlines to avoid delaying your claim. This guide explains the rules, how SIRA's guidelines apply, and steps to challenge delays.

Legal Framework for Assessor Changes

The Motor Accident Injuries Act 2017 and SIRA's guidelines govern CTP claims. While the legislation does not explicitly set a time limit for insurers to change assessors, SIRA's rules require insurers to respond to claim-related requests within 14 days. If an insurer delays or refuses to act on a claimant's request to change assessors, this could constitute a breach of their obligations under the scheme.

SIRA's guidance on claims (https://www.sira.nsw.gov.au/claims/motor-accidents) states that insurers must provide claimants with a clear timeline for assessments and communicate changes promptly. Delays in assessor changes may also violate the Code of Conduct for Motor Accident Claims under the Motor Accident Injuries Regulation 2017.

Practical Steps for Claimants

If your insurer wants to change the assessor, you should:

  • Request a written explanation of the reason for the change
  • Ask for a new assessment timeline
  • Document all communications with the insurer
  • Seek independent medical advice if the new assessor's report conflicts with your treatment records

Evidence such as medical records, correspondence with the insurer, and witness statements may be needed to challenge delays. SIRA's rules also require insurers to provide claimants with a copy of the assessor's report at least 14 days before it is used in determining benefits.

Time Limits and Dispute Options

NSW law does not set a specific time limit for insurers to change assessors, but delays can harm your claim. If an insurer fails to act within a reasonable timeframe (typically 28 days from the request), you may need to:

  • Lodge a formal complaint with SIRA
  • Request a review by the NSW Civil and Administrative Tribunal (NCAT)
  • Seek legal advice if the insurer's actions appear to breach the CTP scheme's rules

Claimants should act quickly if they believe an insurer is unreasonably delaying an assessor change. SIRA's guidelines emphasize that insurers must act in good faith and avoid unnecessary delays.

Example Scenario

Imagine a claimant in Bathurst who is told their assessor will change after 30 days. Under SIRA's rules, the insurer should have informed them of the change within 14 days of the request. If the insurer fails to provide a new timeline or explain the delay, the claimant may have grounds to challenge the change.

When to Seek Advice

If your insurer is delaying an assessor change or refusing to provide a new timeline, contact SIRA or a legal professional. NSW law requires insurers to act reasonably, and delays can affect your ability to claim benefits. Always keep records of all communications with the insurer.
