If a CTP insurer delays payment of your statutory benefits and applies interest, you may have legal recourse. Under NSW law, late payment interest is a statutory right that applies to benefits owed under the Motor Accident Injuries Act 2017. This article explains how to resolve disputes over late payment interest with CTP insurers in Ashfield, including SIRA's dispute resolution processes and practical steps for claimants.

What is late payment interest in NSW CTP claims?

Late payment interest is a legal entitlement that applies when a CTP insurer fails to pay your statutory benefits on time. Under the Motor Accident Injuries Act 2017, interest accrues on unpaid benefits from the due date until payment is made. This applies to weekly income payments, treatment and care benefits, and other statutory entitlements. The interest rate is set by the NSW government and is typically higher than standard commercial rates.

How do CTP insurers handle disputes over late payment interest?

CTP insurers must pay statutory benefits within 28 days of receiving a valid claim. If they delay payment, interest accrues automatically. To dispute a payment, insurers must provide written notice of their decision within 28 days. If you believe the interest calculation is incorrect, you can challenge the insurer's assessment by:

  • Requesting a written explanation of the interest calculation
  • Submitting evidence of your injury and claim timeline
  • Escalating the dispute through SIRA's internal review process

What dispute resolution options are available for claimants in Ashfield?

SIRA provides a structured process for resolving payment disputes:

  1. Internal review: Contact the insurer's internal complaints team within 28 days of the decision
  2. Mediation: SIRA offers free mediation services for unresolved disputes
  3. Legal action: If mediation fails, you may need to pursue a claim in the NSW Civil and Administrative Tribunal (NCAT) or the District Court

SIRA's dispute resolution guidelines (https://www.sira.nsw.gov.au/claims/motor-accidents) outline the steps for challenging interest calculations. Claimants should document all correspondence and keep copies of medical records, accident reports, and payment statements.

How does SIRA guide resolution of payment interest disputes?

SIRA's Motor Accident Claims page (https://www.sira.nsw.gov.au/claims/motor-accidents) explains that interest is calculated based on the date the benefit became due. If you dispute the interest amount, you must:

  • Provide evidence of your injury date and claim timeline
  • Show that the insurer's payment schedule was unreasonable
  • Demonstrate that the interest calculation violates the Motor Accident Injuries Act 2017

SIRA also clarifies that weekly income payments and treatment benefits are subject to the 52-week statutory benefit period. If your claim extends beyond this period, you may need to pursue a common law damages claim separately.

Practical steps for claimants in Ashfield

To resolve a late payment interest dispute:

  • Calculate the interest accrued using the NSW government's interest rate calculator
  • Request a written explanation of the insurer's payment schedule
  • Submit your claim to SIRA's dispute resolution team within 28 days

If your dispute involves a complex injury or long-term care needs, consider seeking legal advice. SIRA's guidelines emphasize that claimants must act promptly to preserve their rights.
