Proving Toxic Exposure Caused Your Illness in California
The heart of a toxic-tort case is causation: showing that the exposure is connected to your illness. It is also the part people worry about most — but the burden of proving the science does not fall on you. It is the work of the case and its experts.
Two connections to establish
These cases generally require establishing two links: that you were meaningfully exposed to the substance, and that the substance is capable of — and did — contribute to your diagnosis. Each is built with evidence, not assumption.
The evidence that builds causation
Proof typically draws on your exposure history (where you worked or lived), environmental or workplace testing and records, your medical records, and the analysis of medical and scientific experts. Preserving this evidence early, before conditions and records change, strengthens the connection.

Frequently asked questions
How can I prove a chemical caused my illness if it was years ago?
You do not have to prove it yourself. The case builds causation using your exposure history, testing and records, your medical history, and expert analysis. Even for older exposures, this evidence can establish the connection. A free review can assess what is possible.
California law — what people ask
How long do I have to file an injury claim in California?
Generally two years from the date you were hurt. If a government entity is involved — a city vehicle, a public road, a public hospital — you usually have to present a formal claim to that agency within roughly six months before you can sue at all, which catches people out far more often than the two-year date.
Can I still recover if I was partly at fault in California?
Yes. California uses pure comparative negligence, so your recovery is reduced by your percentage of fault rather than barred — even if your share turns out to be the larger one. There is no cutoff percentage that ends a claim here.
Does California cap what I can recover?
Not in an ordinary injury case. Medical-malpractice claims are the main exception, where non-economic damages are limited by a cap that steps up over time. For most claims — car crashes, falls, defective products — there is no statutory ceiling.
What if more than one person was responsible?
California splits the analysis: defendants can be jointly responsible for your economic losses such as medical bills and lost income, while non-economic damages like pain and suffering are apportioned to each defendant by its own share of fault.
The driver who hit me had no insurance. What now?
Your own uninsured or underinsured motorist coverage is usually the answer, and it commonly applies to hit-and-run collisions as well. Check every policy in the household, not only the one covering the car you were in.
Will the jury hear that my health insurance paid my bills?
Generally not. California follows the collateral source rule, so a wrongdoer does not get credit for insurance you paid for. How your medical damages are measured is a separate and often contested question.
Injury law in California
California injury law shapes your case in a few specific ways worth knowing early.
- Filing deadline: You generally have two years from the date of the injury to file — and only about six months to put a government entity on notice before you can sue.
- Fault: California follows pure comparative negligence, so you can still recover even if you were partly — or mostly — at fault, with your recovery reduced by your share of the blame.
- Damage caps: An ordinary California injury case has no cap on damages; medical-malpractice claims are the main exception.
- Uninsured drivers: California sets minimum auto-insurance limits and uninsured/underinsured-motorist rules that affect what coverage is available.
