Insurer Internal Reviews, Evidence and Records to Keep in Balmain NSW

If you're dealing with an insurer dispute over a NSW Compulsory Third Party (CTP) motor accident claim, understanding what evidence must be retained by insurers and what records you should preserve is critical. Under NSW law, insurers are legally required to keep certain documents during internal reviews of claims. This guide explains the key evidence to retain, how SIRA guidelines apply, and when to seek legal advice.

NSW CTP Rules Behind Insurer Disputes

The Motor Accident Injuries Act 2017 and SIRA guidelines govern how insurers must handle disputes. Insurers must retain all records related to claim assessments, including medical reports, accident details, and internal review notes. This ensures transparency and allows for meaningful reconsideration of decisions. SIRA’s role is to oversee compliance with these rules, ensuring insurers follow the correct procedures when disputes arise.

Practical Evidence for Insurers and Claimants

What Insurers Must Keep

Insurers are required to retain records that demonstrate their decision-making process. This includes:

  • Medical records showing the nature and severity of injuries
  • Accident reports and witness statements
  • Internal review notes documenting the insurer’s assessment
  • Correspondence with claimants or their representatives

These records must be kept for at least 5 years under the Motor Accident Injuries Act 2017. Failure to retain these documents could result in the insurer being unable to justify its decision, potentially leading to a reconsideration.

What Claimants Should Preserve

While insurers must keep records, claimants also need to document their case. Key evidence to retain includes:

  • Detailed medical records, including treatment plans and specialist opinions
  • Police reports and accident scene photographs
  • Witness statements and contact details
  • Income records to support claims for lost wages
  • Correspondence with the insurer, including dates and copies of all communications

For example, if an insurer disputes a claim for soft tissue injuries, medical records showing neurological signs (as defined in the Motor Accident Guidelines) are essential to prove the injury meets the threshold for compensation.

Time Limits and Dispute Resolution

Insurers must complete internal reviews within 28 days of receiving a request for reconsideration. If they fail to act within this timeframe, claimants may have grounds to escalate the matter. Under the Motor Accident Injuries Act 2017, claimants can also request a review by the Personal Injury Commission (PIC) if they disagree with the insurer’s decision. However, it’s important to note that a challenge does not guarantee a change in the insurer’s decision. The PIC will assess whether the insurer followed the correct process, not necessarily whether the claim is correct.

When to Seek Legal Advice

If an insurer refuses to reconsider its decision or disputes the validity of your claim, it’s important to seek legal advice. A solicitor can help you:

  • Review the insurer’s retained records to identify potential errors
  • Prepare a formal dispute request under the correct legal framework
  • Navigate the process of escalating to the PIC or SIRA

Legal advice is particularly important if the insurer’s decision appears to be based on incorrect interpretations of the Motor Accident Guidelines or if there are disputes over medical evidence.

Hypothetical Example

Consider a claimant who was in a car accident in Balmain. The insurer disputes the claim, arguing that the injuries are not threshold injuries. The claimant must provide medical records showing neurological signs, such as a spinal nerve-root injury with clinical evidence. If the insurer’s internal review fails to consider these records, the claimant may have grounds to request a review by the PIC. This example highlights the importance of retaining all evidence during the dispute process.

Next Steps

CTP claims can be complex, and the outcome often depends on the evidence retained by insurers and the records preserved by claimants. If you’re in Balmain and facing an insurer dispute, it’s essential to document all aspects of your case. Every claim depends on its own facts.
