Evidence and Records for CTP Late Payment Interest Claims

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 your Compulsory Third Party (CTP) insurer in Western Sydney is delaying payment of statutory benefits, you may be entitled to interest under NSW law. Proving this requires careful documentation. This article explains what evidence to keep, how to preserve it, and why it matters for your claim.

Legal Framework for CTP Late Payment Interest

NSW CTP claims are governed by the Motor Accident Injuries Act 2017 and SIRA guidelines. Statutory benefits like weekly payments and treatment benefits must be paid within 52 weeks of the injury. If an insurer delays payment beyond this period, interest may accrue under the NSW Civil Procedure Act 2009 (s 22). However, the Motor Accident Injuries Act 2017 s 4.4 limits benefits for injuries that only meet the 'threshold injury' definition after 52 weeks.

SIRA’s What you can claim page confirms that statutory benefits include 'weekly income payments' and 'treatment and care benefits'. Delays in paying these could trigger interest claims, but evidence must show the insurer’s failure to meet statutory deadlines.

Practical Steps to Document Late Payment Interest

To prove a late payment interest claim, retain the following records:

  • Payment records: Bank statements, email confirmations, or written correspondence showing when benefits were or were not paid.
  • Timeline evidence: Document the date of the accident, injury diagnosis, and when you first contacted the insurer. Use a calendar or diary to track dates.
  • Medical records: Ensure your GP or specialist notes clearly link your injury to the accident. SIRA’s Making a motor accident claim page advises that medical evidence is critical for proving injury severity.
  • Insurer communications: Save all emails, letters, or phone records with the insurer. If you received a delayed response, note the date and time of each interaction.
  • Witness statements: If others saw the accident, ask them to provide written accounts of what they observed.

Time Limits and Dispute Resolution

NSW law imposes strict deadlines for CTP claims. Under the Motor Accident Injuries Act 2017 s 3.28, you must notify the insurer of your injury within 52 weeks. If you fail to meet this deadline, you may lose your right to claim benefits. However, if the insurer caused the delay (e.g., by not responding to your claim), you may still pursue interest claims.

  • If your insurer disputes the interest claim, you may need to apply to the NSW Civil and Administrative Tribunal (NCAT) under s 22 of the
  • NSW Civil Procedure Act 2009*. SIRA’s
  • Motor accident claims* page outlines that NCAT can resolve disputes about benefit calculations and payment timelines.

Example: What Happens if Evidence is Lost?

Consider a scenario where a claimant in Western Sydney receives a delayed payment of weekly benefits. Without evidence of the insurer’s failure to meet the 52-week deadline, the claimant may lose the right to interest. This highlights the importance of preserving records like bank statements and correspondence.

When to Seek Legal Advice
