It outlines when offers may be disputed and what evidence to gather, with practical steps for injured people in Auburn and elsewhere.

Current as at 7 October 2026

If you have been offered a lump sum settlement under NSW’s Compulsory Third Party (CTP) scheme following a motor vehicle accident, you may have concerns about whether the offer is fair, what it covers and whether you should accept it. This article explains how CTP lump sum offers are calculated under the Motor Accident Injuries Act 2017, what factors influence the amount, and when you may have grounds to dispute it. The information applies to claims arising from accidents in NSW, including those in Auburn, and is based on current SIRA guidelines and legislation.

What Is a CTP Lump Sum Settlement Offer?

A lump sum settlement is a single payment made under the CTP scheme to resolve a claim for injury resulting from a motor vehicle accident. It is intended to cover all past and future losses, including medical and treatment expenses, lost income, and pain and suffering. The offer is made by the insurer of the at-fault vehicle, and it is not a guaranteed entitlement.

The offer is based on the nature and severity of the injury, the impact on daily life and work, and the claimant’s pre-accident circumstances. It is calculated using the Motor Accident Guidelines issued by the State Insurance Regulatory Authority (SIRA). These guidelines set out how different injuries are assessed and what lump sum amounts are considered appropriate.

How Is the Lump Sum Amount Determined?

The amount offered depends on several factors. The most significant is whether the injury is classified as a threshold injury or a more serious whole person impairment (WPI).

A threshold injury includes soft tissue injuries such as whiplash, sprains, or strains. Under the Motor Accident Injuries Act 2017, a soft tissue injury is defined as an injury to the soft tissues of the body, including ligaments, tendons, or muscles, that results in a measurable loss of function. This includes injuries to the spinal nerve roots if they produce neurological signs other than radiculopathy.

For threshold injuries, weekly benefits and treatment and care benefits are generally limited to 52 weeks after the accident, unless the injury results in a permanent impairment. A lump sum offer may still be made if the injury has long-term effects, but it will typically be lower than for more serious injuries.

For injuries resulting in a WPI of 10% or more, the lump sum is calculated using a formula based on the impairment rating, age, and pre-accident income. The higher the WPI, the greater the lump sum. For example, a claimant with a 30% WPI may receive a significantly higher amount than someone with a 10% WPI.

When Might a Lump Sum Offer Be Disputed?

You may have grounds to dispute a lump sum offer if you believe it does not reflect the full extent of your injury and losses. Common reasons for disputing an offer include:

  • The injury is not properly assessed, particularly if it includes chronic pain, ongoing treatment needs, or psychological impact.
  • Medical evidence shows a higher level of impairment than the insurer acknowledges.
  • The offer does not account for future medical treatment, loss of income, or changes to daily life.

If you disagree with the offer, you can request a review from the insurer. If the insurer does not change the offer, you may apply to the NSW Civil and Administrative Tribunal (NCAT) to determine the correct amount. This process is available for claims involving a WPI of 10% or more, or for claims where the injury is not a threshold injury.

What Evidence Supports a Lump Sum Claim?

To assess whether a lump sum offer is fair, you should gather and review the following evidence:

  • Medical records from your GP, specialists, and treatment providers, including reports on diagnosis, treatment, and prognosis.
  • A report from a registered medical practitioner assessing your whole person impairment, if applicable.
  • Evidence of lost income, including payslips, employer letters, or tax returns.
  • Photographs of the accident scene, vehicle damage, or injuries, if available.
  • Witness statements, if you have them.

A second opinion from a specialist medical practitioner may be useful if the insurer disputes your medical evidence. This is particularly relevant if you have a complex injury such as a spinal nerve-root injury with neurological signs, or if you are experiencing long-term pain or disability.

Practical Steps After Receiving an Offer

If you have received a lump sum offer, take the following steps:

  1. Review the offer carefully and compare it to SIRA’s Motor Accident Guidelines.
  2. Check that your injury is accurately described in the offer and that all relevant medical evidence has been considered.
  3. Seek independent advice from a solicitor or a medical expert if you are unsure whether the offer is fair.
  4. Do not accept or reject the offer without fully understanding your rights and options.

Time limits apply to certain claims. For example, if you are seeking damages, you must file a claim within three years of the accident. It is important to act promptly if you wish to dispute the offer.

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
