If you were hurt because of someone else's carelessness in California, the first question on your mind is probably: do I actually have a case? The honest answer is: it depends on the specific facts. But there are six concrete signs that personal injury attorneys look for when evaluating whether a claim is strong. Every one of them is grounded in California law and built on evidence, not wishful thinking.
Here is what a strong case looks like, item by item.
Quick answer, the 6 signs at a glance:
- Clear liability: the other party breached a duty of care and caused your injury.
- Documented injuries with a consistent medical treatment record.
- Real, provable economic losses, bills, pay stubs, invoices.
- Collectible insurance coverage or a solvent defendant.
- Strong contemporaneous evidence: photos, video, witnesses.
- You acted fast: filed within the statute of limitations and met any early notice deadlines.
If your situation checks most of these boxes, a free case review with a personal injury attorney is the logical next step. Call (818) 794-9947, no fee unless we win.
1. Clear Liability, the Other Party Plainly Caused It
The foundation of every personal injury case is liability: someone owed you a duty of care, they breached it, and that breach caused your injury.
Cal. Civ. Code §1714 states that every person is responsible for injuries caused to another by a want of ordinary care or skill in the management of their property or person. That is the legal duty that runs between a driver and other road users, a property owner and guests, an employer and its employees, a manufacturer and product users.
The stronger and cleaner the breach, the stronger your case. A driver who ran a red light on dashcam video is a clear liability case. A driver whose speed was "probably" a little high is a harder one. Clear liability means:
- The defendant's action (or failure to act) directly caused the incident.
- The cause-and-effect chain between their conduct and your injury is short and obvious.
- Comparative fault on your side is low or absent. California follows a pure comparative negligence rule, meaning your recovery is reduced proportionally if you share some fault, but it is not eliminated unless you were entirely responsible.
Practical takeaway: If a police report, a witness, or a surveillance video already points clearly at the other party, your liability picture is strong from day one.
2. Documented Injuries with Consistent Treatment
You were hurt. But can you prove it, and prove the injury came from this incident, not something else?
Medical documentation is the backbone of a personal injury claim. What matters most:
The records start at or near the date of the incident. Going to the emergency room or an urgent care clinic the same day or the next day creates a contemporaneous paper trail that is extremely hard for an insurer to attack.
Treatment is consistent. If you saw a doctor once and then stopped, an adjuster will argue the injury healed quickly or was not serious. Regular follow-up visits, with a primary care physician, an orthopedist, a neurologist, a physical therapist, or whoever your treating physicians direct you to, document the ongoing impact of the injury on your life.
The diagnosis matches the mechanism of injury. A lumbar strain from a rear-end collision. A traumatic brain injury from a pedestrian knockdown. A fractured wrist from a slip-and-fall. When the type of injury is consistent with how the accident happened, it is much harder for the defense to argue the injury pre-existed or was fabricated.
Gaps in treatment are one of the most effective tools insurance adjusters use to reduce or deny claims. A six-week break in care, even if explained by finances, transportation, or life circumstances, will be used against you. If you have a legitimate reason for a gap, document it with your treating provider.
Practical takeaway: Seek care immediately after any injury. Keep every appointment. Request your records. Your medical file is your case file.
3. Real, Provable Economic Losses
California allows injured plaintiffs to recover two categories of damages under Cal. Civ. Code §3333: economic damages and non-economic damages.
Economic damages are the measurable, out-of-pocket losses:
- Medical expenses already incurred (emergency room, surgery, physical therapy, prescriptions, medical equipment).
- Future medical expenses if the injury requires ongoing or future care (documented by a treating physician or a life-care planner in serious cases).
- Lost wages for time you could not work due to the injury, documented with employer letters and pay stubs.
- Diminished earning capacity if the injury limits what you can earn going forward.
Non-economic damages cover pain and suffering, emotional distress, and loss of enjoyment of life. California does not cap non-economic damages in most personal injury cases (there is a cap in medical malpractice cases under Cal. Civ. Code §3333.2, but that is a separate rule).
The stronger your paper trail, the stronger your claim. Cases with six-figure medical bills, documented lost income, and credible expert testimony on future care are worth significantly more than cases where the plaintiff felt hurt but never saw a doctor or missed work.
Practical takeaway: Keep every bill, every explanation of benefits from your insurer, every pay stub, and every written communication from your employer about missed work. Economic damages are only as strong as the documents that prove them.
4. Available Insurance Coverage to Collect From
A legally airtight case is worth nothing if there is no money at the end. Collectability is one of the most overlooked factors in evaluating case strength, and it is one of the first things an experienced attorney examines.
Sources of coverage to identify early:
The at-fault party's liability insurance. In a vehicle collision, California requires drivers to carry bodily-injury liability coverage. For policies issued or renewed on or after January 1, 2025, the minimum limit is $30,000 per person under the updated requirements set by Senate Bill 1107. Many defendants carry more. A commercial driver, a trucking company, or a business owner may carry far higher limits.
Your own uninsured/underinsured motorist (UM/UIM) coverage. If the at-fault driver has no insurance or minimum limits that do not cover your losses, your own UM/UIM policy becomes a critical backstop. California insurers are required to offer UM/UIM coverage when they issue an auto policy under Cal. Ins. Code §11580.2.
A business or property owner's general liability policy. Slip-and-falls on commercial property, dog bites, or injuries on a residential property are often covered by the owner's liability insurance.
The defendant's personal assets. If there is no insurance, a solvent defendant with attachable assets (real property, bank accounts, business interests) can still produce a recovery, though collection is harder and slower.
If the at-fault party carries only the state minimum and has no other collectible assets, that limits the realistic value of your claim regardless of how strong the liability picture is. An attorney can help you identify every layer of coverage available before you decide how to proceed.
Practical takeaway: Before you can assess the value of your case, you need to know what you can actually collect. Identifying insurance coverage is a day-one priority.
5. Strong Evidence, Photos, Video, and Witnesses
Evidence locks facts in place. The sooner it is gathered, the harder it is for the other side to rewrite the story.
Photographic and video evidence. Scene photographs taken at the time of the incident, skid marks, damaged vehicles, a wet floor with no warning sign, a broken stair, capture conditions that change within hours. Surveillance camera footage from a business, a traffic camera recording, or a dashcam video can be definitive. Many cameras overwrite their footage within 24-72 hours. A preservation letter (or litigation hold) must go out fast.
Witness information. An independent eyewitness who saw the incident happen and has no connection to either party is among the most credible evidence available. Their account, taken while memory is fresh, can be the deciding factor when liability is disputed. Collect names and phone numbers at the scene.
Police and incident reports. A responding officer's report documents the at-fault party's statements, observed conditions, and any citations issued. Request a copy as soon as it is available.
Physical evidence. Defective products, worn-out equipment, broken guardrails, or missing safety devices are physical evidence. They should be preserved and not repaired or discarded before a claim is filed.
The sooner evidence is gathered and preserved, the stronger the case. Memories fade. Surveillance footage is overwritten. Scene conditions are repaired. Weather washes away skid marks. Speed matters here in a way that directly affects case outcome.
Practical takeaway: Photograph everything at the scene, get witness contact information, and call an attorney the same day so a preservation demand can go out immediately.
6. You Acted Quickly and Preserved Your Rights
Timing is not just a formality in California personal injury law. Missing a deadline does not weaken your case, it ends it.
The general statute of limitations. Under Cal. Code Civ. Proc. §335.1, you have two years from the date of injury to file a personal injury lawsuit in California. Miss that date and the court will dismiss your case, regardless of how strong the liability or damages picture is.
Government defendants: an earlier, separate deadline. If your injury was caused by a public entity, a city, a county, CalTrans, a school district, a transit authority, the rules are different and stricter. Before you can sue, you must first present a government tort claim within six months of the incident under Cal. Gov. Code §911.2. If the government entity rejects the claim (or takes no action), you then have a limited additional period to file suit. Miss the six-month presentation window and you generally lose the right to sue the government entirely.
Insurance notice requirements. Most liability policies require prompt notice of a claim. Unreasonable delay in reporting can give an insurer grounds to deny coverage.
Evidence preservation. Acting quickly is not just about legal deadlines. As noted above, surveillance footage is overwritten, witnesses move, and physical evidence disappears. The sooner an attorney sends a preservation letter and begins gathering evidence, the stronger the case file.
California's general personal injury statute of limitations is two years from the date of injury under Cal. Code Civ. Proc. §335.1.
If you are suing a California government entity, you must present a tort claim within six months of the incident under Cal. Gov. Code §911.2, before you can file a lawsuit at all.
Practical takeaway: If you were hurt, do not wait to see how you feel in a few weeks. Every day you delay is a day closer to a deadline that could eliminate your case entirely.
How Many Signs Do You Need?
There is no magic score. But here is how experienced attorneys think about it:
A case with all six signs, clear liability, documented injuries, provable losses, collectible coverage, strong evidence, and timely action, is as strong as a personal injury claim gets in California. These are the cases that settle at full value before trial.
A case with four or five signs may still be worth pursuing, depending on which signs are present and how strong each one is. Clear liability plus documented serious injury plus adequate insurance coverage is often enough to build a compelling claim even if the evidence picture needs development.
A case with only one or two signs, especially if collectability is missing, is worth discussing with an attorney before investing time and money into a claim that may not produce a recovery.
The only way to know for certain is to have an attorney evaluate your specific facts. That is what a free case review is for.

Frequently Asked Questions
How do I know if I have a good injury case in California?
The clearest indicators are: someone else clearly caused the incident, you sought medical care promptly and kept up with treatment, you have documented financial losses, and there is insurance or assets available to pay a judgment. An attorney can assess all four factors in a free consultation.
What makes a personal injury claim strong?
Strong claims have three things working together: clear liability (the defendant breached a duty of care under Cal. Civ. Code §1714), substantial provable damages, and a realistic way to collect. Cases where all three align tend to settle for fair value without going to trial.
Should I file a personal injury claim in California?
If you were injured because of someone else's negligence and you have medical bills, lost wages, or lasting physical limitations, filing a claim is worth serious consideration. The two-year statute of limitations under Cal. Code Civ. Proc. §335.1 means the decision cannot wait indefinitely. A free case review costs you nothing and gives you the information you need to decide.
What is the statute of limitations for personal injury in California?
The general deadline is two years from the date of injury under Cal. Code Civ. Proc. §335.1. Important exceptions: claims against a government entity require a tort claim presentation within six months of the incident under Cal. Gov. Code §911.2, and claims involving minors or delayed injury discovery have their own rules.
Does comparative fault affect my California personal injury case?
Yes. California uses a pure comparative negligence system, meaning your recovery is reduced by your percentage of fault. If you were 20% at fault and your damages are $100,000, you recover $80,000. You can still recover even if you were more than 50% at fault, unlike in some other states.
What if the at-fault driver has no insurance or minimum coverage?
Your own uninsured/underinsured motorist (UM/UIM) policy may cover the gap. California insurers are required to offer UM/UIM coverage when issuing an auto policy under Cal. Ins. Code §11580.2. An attorney can help you identify every available coverage layer, including the at-fault party's policy, your own UM/UIM, and any applicable umbrella policies, before you decide whether and how to proceed.
Do I need a lawyer to file a personal injury claim in California?
You are not legally required to hire an attorney. But unrepresented claimants typically receive lower settlements because insurance adjusters know that without legal representation, a case is unlikely to go to trial. An attorney also handles evidence preservation, medical record gathering, and deadline compliance, all of which directly affect case strength.
