Being involved in a car accident is stressful enough, but when you have a pre-existing medical condition, the claims process can become considerably more complex. Understanding how your previous injuries or health conditions might impact your compensation claim is vital for protecting your legal rights. If you’re facing this situation, Melbourne car injury lawyers recommend understanding the legal nuances that could affect your case outcome.
Key Takeaways
- Pre-existing conditions don’t automatically disqualify you from compensation, but they can affect your claim’s value
- Australian law recognises the ‘eggshell skull rule’ – you take your victim as you find them
- Detailed medical evidence is crucial to distinguish between aggravation of existing conditions and new injuries
- Insurers often scrutinise claims involving pre-existing conditions more heavily
- Early legal advice can help protect your claim when pre-existing conditions are involved
How Pre-existing Conditions Are Treated Under Australian Law
Australian compensation law follows several key principles when dealing with pre-existing conditions. The most fundamental is the concept of causation – establishing a direct link between the accident and your current symptoms.
Courts apply the ‘but for’ test: would your current condition exist ‘but for’ the accident? Additionally, the ‘eggshell skull rule’ states that a defendant must take their victim as they find them, meaning increased vulnerability due to pre-existing conditions doesn’t reduce liability.
Different states have varying approaches. In Victoria, the Transport Accident Commission scheme handles car accident claims differently than Queensland’s CTP scheme or NSW’s Motor Accidents Compensation scheme, particularly regarding pre-existing conditions.
Evidence Needed to Link the Accident and the Injury
The success of your claim often hinges on medical documentation. You’ll need:
- Complete medical history records showing your condition before the accident
- Detailed post-accident medical assessments
- Expert medical reports addressing causation questions
- Objective evidence like MRIs, X-rays and functional capacity assessments
- Treatment records showing changes in medication or therapy after the accident
Medical experts must specifically address whether the accident caused a new injury, aggravated an existing condition, or had no impact on your pre-existing health issues.
How Insurers Assess Pre-existing Conditions
Insurance companies approach pre-existing conditions with particular scrutiny. Common insurer tactics include:
“When dealing with insurers, transparency about pre-existing conditions is essential, but so is having proper medical evidence that clearly differentiates between prior symptoms and accident-related aggravation or new injuries.” – National Compensation Lawyers
Insurers typically request extensive medical records, often going back years before the accident. They look for similar complaints or treatment patterns that might suggest your current symptoms aren’t accident-related.
When responding to insurer requests, be honest but precise. Distinguish between occasional minor symptoms before the accident and serious ongoing issues after. Never exaggerate the difference, as medical records will likely reveal inconsistencies.
Apportionment and Reduction of Damages
When a pre-existing condition contributes to your current symptoms, courts may apportion damages – assigning percentages of responsibility between the accident and your prior condition.
For example, if you had degenerative disc disease that was asymptomatic before the accident but now causes pain, a medical expert might determine the accident is 70% responsible for your current symptoms, with the natural progression of the disease accounting for 30%.
Apportionment calculations vary by jurisdiction and injury type. Some claims achieve full compensation despite pre-existing conditions, while others face substantial reductions or outright denial.
Selecting and Working with Medical Experts
The right medical expert can make or break your claim. Depending on your injuries, you might need reports from:
– Orthopaedic surgeons for musculoskeletal injuries
– Neurologists for brain injuries or nerve damage
– Psychiatrists for psychological trauma
– Rehabilitation physicians for long-term functional assessments
Effective expert reports should clearly address your baseline condition before the accident, the specific impact of the accident, and distinguish natural degeneration from accident-related aggravation.
Common pitfalls include experts who make conclusive statements without sufficient evidence or fail to explicitly connect the accident to current symptoms.
Practical Steps to Protect Your Claim
If you have a pre-existing condition and experience a car accident, take these steps to strengthen your claim:
1. Seek immediate medical attention and clearly report all new symptoms
2. Document the accident thoroughly with photos and witness information
3. Maintain a symptom diary comparing pre and post-accident conditions
4. Gather medical records from before the accident
5. Follow all treatment plans diligently
6. Be honest with healthcare providers about prior conditions
Legal Timeframes and Procedures in Australia
Time limits for car accident claims vary across Australia, ranging from 28 days for initial notification to three years for filing court proceedings. Missing these deadlines can invalidate your claim entirely.

Most jurisdictions require compulsory pre-litigation steps like medical assessments and settlement conferences before court proceedings. Cases involving pre-existing conditions often benefit from mediation, where complex medical evidence can be thoroughly discussed.
The resolution timeframe for claims with pre-existing conditions typically extends beyond standard claims, sometimes taking 18-36 months depending on complexity.
Frequently Asked Questions
Will a past injury always reduce my compensation?
No, not necessarily. If the accident clearly aggravated your condition or caused new symptoms, you may still receive full compensation.
Can I claim for worsening of a pre-existing condition?
Yes, Australian law recognises compensation for aggravation of pre-existing conditions when caused by the negligence of another party.
What if the insurer claims my condition caused the crash?
This raises causation issues that require expert evidence to address, particularly for conditions that might affect driving capacity.
How long does resolving these claims take?
Claims involving pre-existing conditions typically take longer – often 18-36 months compared to 12-24 months for standard claims.
Conclusion
Pre-existing conditions add layers of complexity to car accident claims, but they don’t automatically diminish your right to compensation. Success hinges on strong medical evidence that clearly distinguishes between your baseline condition and accident-related changes.
Document everything meticulously, be transparent but precise with insurers, and consider seeking qualified legal advice early in the process. With proper preparation and expert guidance, many claimants successfully navigate these challenging cases.
