Evidence is the foundation of claim value. A well-documented claim with comprehensive medical records, clear liability evidence, and itemised financial losses will settle for more than an identical injury with gaps in documentation. Adjusters discount what they cannot verify.
TL;DR.
Five pillars: liability evidence, medical records, financial documentation, expert reports, and daily-impact evidence. Gaps in any pillar reduce value. The most costly gap: delayed or inconsistent medical treatment.
Liability evidence
| Evidence type | Purpose | Impact on value |
|---|---|---|
| Police / accident report | Official record of fault determination | High — strong if favourable |
| Photographs / video | Scene, vehicle damage, injuries | High — objective visual evidence |
| Dashcam / CCTV footage | Real-time record of the incident | Very high — often dispositive |
| Witness statements | Corroborate the claimant's account | Moderate to high |
| Accident reconstruction | Expert analysis of mechanics and forces | High in disputed liability cases |
Medical evidence
- Emergency room records — first medical documentation after the accident
- Specialist referrals — orthopaedic, neurological, pain management
- Diagnostic imaging — X-ray, MRI, CT confirming injury
- Treatment notes — consistent, dated records of every visit
- Surgical records — operative notes, hardware documentation
- Prognosis report — expected recovery, permanent impairment rating
WarningTreatment gaps are the most common evidence weakness. If you stop treatment for weeks or months, the adjuster will argue the injury resolved — even if you were simply too busy, uninsured, or waiting for authorisation. Document any reason for gaps.
Financial evidence
| Evidence | What it proves |
|---|---|
| Medical bills | Special damages — past medical costs |
| Pay stubs / employment records | Lost wages (past) |
| Tax returns | Pre-injury earning capacity |
| Employer verification letter | Missed work dates and pay rate |
| Receipts | Out-of-pocket expenses (transport, medications, home help) |
Expert reports
- Independent medical examination (IME) — specialist assessment of injuries
- Economic expert — future lost earnings and economic losses
- Life-care planner — future medical and care costs (catastrophic cases)
- Vocational expert — impact on employability and earning capacity
Daily impact documentation
- Pain diary — daily log of pain levels and limitations
- Activity log — what you can and cannot do compared to pre-injury
- Witness statements from family — corroborate impact on daily life
Frequently asked questions
What evidence do I need for a personal injury claim?
Five categories: (1) liability evidence (police report, witness statements, photographs/video, accident reconstruction), (2) medical records (ER, specialist, diagnostic imaging, treatment notes), (3) financial evidence (bills, pay stubs, tax returns for lost wages), (4) expert reports (medical, economic, life-care planning), and (5) documentation of daily impact (pain diary, activity logs).
Does a police report help a claim?
Significantly. A police report that attributes fault to the other party is powerful evidence. However, a police report is not legally binding — it is one piece of evidence. Cases can succeed even with unfavourable police reports if other evidence supports liability.
What if I did not get immediate medical treatment?
Delayed treatment creates a gap that insurers exploit. The adjuster will argue that the injury was not serious or was caused by something other than the accident. Seek medical attention as soon as symptoms appear and document the reason for any delay.
