SIRA guidelines emphasize the need for documented proof of unpaid benefits. Seek legal advice if disputes arise, as time limits apply. Complete the enquiry form to discuss your case.

When a Compulsory Third Party (CTP) insurer delays payment of interest on statutory benefits, claimants must retain specific evidence to support their case. Under NSW law, interest is calculated on unpaid statutory benefits, and delays can affect the total amount owed. This article explains the legal requirements for evidence, practical steps to document delays, and how to apply SIRA guidelines to support claims in Armidale NSW.

Legal Framework for Late Payment Interest

Under the Motor Accident Injuries Act 2017, statutory benefits such as weekly payments and treatment benefits accrue interest if not paid on time. Section 4.4 of the Act specifies that interest applies to unpaid benefits, and the Motor Accident Injuries Regulation 2017 outlines the calculation method. SIRA (State Insurance Regulatory Authority) confirms that interest is added to unpaid benefits from the due date until payment, as detailed in its Motor Accident Claims guidelines.

Evidence to Prove Late Payment of Interest

To establish a claim for delayed interest, claimants must retain records that prove the insurer’s failure to pay on time. Key evidence includes:

  • Proof of due dates: Documents showing when benefits were owed (e.g., payment schedules, correspondence).
  • Communication records: Emails, letters, or notes showing delays in payment.
  • Interest calculation records: Screenshots or printouts of interest calculations provided by the insurer.
  • Witness statements: Testimonies from others confirming payment delays.
  • Payment receipts: Proof of when benefits were finally paid (if applicable).

Practical Steps to Document Delays

Claimants should take the following steps to preserve evidence:

  1. Log all communication with the insurer, including dates and details of conversations.
  2. Keep copies of all correspondence, including emails, letters, and phone records.
  3. Track interest calculations by noting the insurer’s stated rates and how they apply to unpaid benefits.
  4. Maintain medical and financial records to show the impact of delayed payments.
  5. Request written confirmation of payment dates from the insurer.

SIRA Guidance on Evidence Requirements

SIRA’s What You Can Claim page confirms that claimants must provide evidence of unpaid benefits and interest. It also advises that claimants should seek resolution with the insurer before escalating disputes. If delays persist, claimants may need to file a complaint with SIRA or pursue legal action.

Time Limits and When to Seek Advice

NSW law imposes time limits for disputing payment delays. While the exact deadline depends on the circumstances, claimants should act promptly to preserve evidence. If the insurer refuses to pay interest or disputes the claim, seeking legal advice is essential. A solicitor can help claimants understand their rights under the Motor Accident Injuries Act 2017 and ensure all evidence is properly presented.

Example Scenario

Consider a claimant who received weekly payments for 26 weeks but faced a 12-week delay in receiving interest on those benefits. By retaining records of the due dates, communication with the insurer, and interest calculations, the claimant could demonstrate that the insurer owed additional compensation. This example highlights the importance of thorough documentation.
