When dealing with a personal injury claim, it is easy to make costly mistakes. Most of them happen in the first days and weeks, before you fully understand what your claim is worth, and they are difficult or impossible to undo later. Below are the eight mistakes we see most often in California personal injury claims and how to avoid each one. If you are unsure about your next step, call Cefali & Cefali at (949) 325-7790 for a free consultation, available 24/7.
1. Delaying Medical Treatment
See a doctor as soon as possible after an accident, even if you think your injuries are minor or you have no obvious symptoms. Some injuries, including concussions, soft tissue damage, and internal injuries, do not present symptoms until hours or days later. Prompt medical care does two things: it protects your health, and it creates the documented link between the accident and your injuries that your entire claim rests on. Insurance companies treat any gap between the accident and your first treatment as evidence that you were not really hurt. Once you start treatment, follow your providers' recommendations and attend every appointment, because missed appointments get used against you the same way.
2. Admitting Fault at the Scene
A simple "I'm sorry this happened" is fine. Elaborating is not. Statements like "I did not even see you" or "I was in a hurry" can be treated as admissions and used to assign you a share of fault. California's comparative negligence rules reduce your recovery by your percentage of fault, so every offhand comment that shifts blame toward you costs you money. Stick to facts when speaking with the other driver, witnesses, and police.
3. Giving a Recorded Statement to the Other Driver's Insurance Company
The at-fault insurance company will contact you quickly, often within a day or two, and ask for a recorded statement. Their adjusters are trained to ask misleading questions, hunt for inconsistencies in your account, and suggest you may be exaggerating your injuries. You have no obligation to give the other side a recorded statement, and you should not. Only your own insurance company can require your cooperation under your policy. We cover this and the other early-days traps in our guide to the first week after a car accident.
4. Signing a Release of Liability or Medical Authorization Too Early
When there is clear evidence their insured is at fault, insurance companies often rush out a settlement offer with a Release of Liability form attached. The minute you sign that form, you give up your right to pursue the other party for anything more, even if your injuries turn out to be far worse than you knew. Never sign a release before you understand the full extent of your injuries, and have an attorney review it first.
The same caution applies to medical authorizations. A blanket authorization gives the insurance company access to your entire medical history, which they will mine for pre-existing conditions to blame your injuries on. Provide only the records relevant to the accident, with health insurance payment information redacted.
5. Failing to Collect and Preserve Evidence
As the injured party, you carry the burden of proving negligence. The more evidence collected right after the accident, the stronger your position. Photograph and video the scene, the vehicles, road conditions, and your visible injuries. Get contact information from witnesses before they leave. Keep a daily journal of your symptoms and track every expense related to the accident. And get the official record: our guide on how to get a police report for a car accident walks through the process for CHP and local agencies.
6. Posting About Your Accident on Social Media
Insurance defense teams routinely monitor claimants' social media. Photos, location check-ins, and casual comments get taken out of context to argue you are not as injured as you claim, and even private posts can be obtained through litigation. The safest approach while your claim is pending is simple: do not post about the accident, your injuries, or your activities at all.
7. Accepting the First Settlement Offer
Early offers are calibrated to close your claim before its full value is known, which is why they tend to arrive fast when fault is clear. Once your treatment is complete and your damages are documented, you negotiate from evidence instead of guesswork. For a practical walkthrough of demand letters and negotiation, including the deadline requirements under California Code of Civil Procedure section 999 that most older guides get wrong, see our guide on maximizing the value of your personal injury case.
8. Missing California's Deadlines
Three deadlines matter in most California injury claims. You generally have two years from the date of injury to file a lawsuit under Code of Civil Procedure section 335.1. If a government entity is involved, you must file a government claim within six months. And after a car accident involving injury, death, or property damage over $1,000, you must file an SR-1 form with the DMV within 10 days under Vehicle Code section 16000. Miss the lawsuit deadline and your claim is over regardless of how strong it is. See our full breakdown of how long you have to report an accident.
Bonus Mistake: Handling a Serious Claim Alone
Minor claims with clear liability can sometimes be handled without a lawyer. But when injuries are significant, liability is disputed, or the insurer is delaying and lowballing, self-representation usually costs far more than a contingency fee would. Experienced personal injury attorneys know the insurance company playbook, how to value a claim properly, and how to apply the leverage that gets cases paid. Since fees are contingency-based, there is no cost to finding out where you stand.
Frequently Asked Questions
What is the biggest mistake people make in a personal injury claim?
Delaying medical treatment. It harms your recovery and gives the insurance company its favorite argument: that your injuries were minor or unrelated to the accident. Get examined within 24 hours and follow through on all recommended treatment.
Should I talk to the other driver's insurance company?
You are not required to, and you should not give them a recorded statement. Anything you say can be used to reduce or deny your claim. Direct them to your attorney, or keep communication in writing until you have one.
What is a Release of Liability form?
A document that ends your claim in exchange for the settlement payment. Once signed, you cannot pursue the other party for additional compensation, even if your injuries worsen. Never sign one before your treatment is complete and an attorney has reviewed it.
Can social media really hurt my injury claim?
Yes. Defense teams monitor claimants' profiles for photos and posts that contradict the injury claims, and even private content can be obtained in litigation. Do not post about the accident, your injuries, or your activities while your claim is pending.
How long do I have to file a personal injury lawsuit in California?
Generally two years from the date of injury under Code of Civil Procedure section 335.1. Claims against government entities require a government claim within six months. Car accidents also require a DMV SR-1 filing within 10 days if there was injury, death, or property damage over $1,000.
Why do insurance companies make fast settlement offers?
When fault is clear, insurers try to settle before you understand the full extent of your injuries and damages. A fast offer is usually a low offer. Wait until treatment is complete and your damages are documented before negotiating.
Do I need a lawyer for a minor injury claim?
Not always. Minor claims with clear liability and short-term treatment can often be handled on your own. Bring in a lawyer when injuries are significant, liability is disputed, or the insurer is stalling or lowballing.
