How contributory negligence affects CTP claims involving caregivers in Western Sydney

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

If a family member or caregiver contributed to an injury, NSW CTP compensation may be reduced. The Motor Accident Injuries Act 2017 and SIRA guidelines determine how shared fault impacts claims. Families in Western Sydney should understand how contributory negligence is assessed, what evidence matters, and when to seek legal advice.

Key legal rules behind contributory negligence in CTP claims

NSW CTP compensation is based on fault. If a claimant or their caregiver contributed to the injury, the compensation amount may decrease. For example, if a caregiver failed to follow medical advice, this could be considered contributory negligence.

SIRA guidelines state that contributory negligence must be 'directly related to the injury' to reduce compensation. This means the family member's actions must have a clear connection to the harm. For instance, if a caregiver ignored a doctor's warning about a pre-existing condition, this could affect the claim.

The threshold injury rules also apply. If the injury is minor (e.g., a soft tissue injury), the 52-week benefits limit may apply. However, contributory negligence is assessed separately and does not automatically trigger this limit.

Practical evidence and steps for families in Western Sydney

Families should gather evidence to support or challenge claims of contributory negligence. Key documents include:

  • Medical records showing the injury's cause and treatment
  • Witness statements from family members or caregivers
  • Accident reports detailing the incident
  • Proof of any pre-existing conditions or prior injuries

Caregivers should also document their role in the claimant's recovery. For example, if a caregiver refused to follow a rehabilitation plan, this could be used to argue contributory negligence.

Time limits and when to seek legal advice

CTP claims must be submitted within 52 weeks of the injury (or 5 years for some cases). If a family member's actions are challenged as contributory negligence, legal advice should be sought before the 52-week deadline.

Disputes over contributory negligence can be resolved through SIRA's dispute resolution process. Families should contact SIRA or a solicitor if they believe their claim is being unfairly reduced.

Example: How contributory negligence affects a family claim

A 65-year-old woman in Western Sydney was injured in a car accident. Her son, who was her primary caregiver, refused to take her to medical appointments. SIRA assessed that the son's failure to seek treatment contributed to the injury's severity. As a result, the compensation was reduced by 20%.

This example shows how family dynamics can directly impact CTP outcomes. Families must ensure all evidence is properly documented and reviewed.
