A car accident lawsuit is a civil case filed in superior court against the driver — and sometimes others — alleged to have caused a collision. It is not the same thing as an insurance claim. Most California car accident claims are resolved with an insurer and never become lawsuits; a lawsuit is what happens when the claim cannot be resolved, or when a filing deadline is about to expire and the claim has to be preserved. In California most injury suits must be filed within two years of the injury, and once filed a case moves through pleadings, discovery, and settlement efforts before any trial date matters.
This page explains when a lawsuit gets filed, who can be named, which court hears the case, and what actually happens after filing. It is written for someone who was injured and is considering a claim.
Key Points
- Filing a lawsuit does not end negotiation. Most cases that are filed still resolve before trial.
- Injury and property damage carry different deadlines, and a claim involving a public entity carries a much shorter one.
- Whom you can sue is not limited to the other driver — a vehicle owner or an employer may also be a proper defendant.
- Cases over $35,000 are filed as unlimited civil cases; $35,000 or less is a limited civil case, and small claims has a lower ceiling still.
- A lawsuit does not remove the underlying problems in a claim. Fault still has to be proven, comparative fault still reduces a recovery, and the defendant’s insurance limits still constrain what is realistically collectible.
- No lawyer can tell you what a case will be worth or whether it will succeed.
Most Claims Never Become Lawsuits
The ordinary path after a collision is an insurance claim: you notify the insurers, treatment happens, records and bills are assembled, a demand is made, and the claim is negotiated. Nothing is filed in court and no judge is involved.
A lawsuit generally gets filed for one of a few reasons:
- Liability is disputed. The insurer takes the position that its driver was not at fault, or that you were substantially responsible.
- Causation or treatment is disputed. The insurer accepts fault but argues the injuries came from something else, or that the care was excessive.
- The valuation gap will not close. Negotiation has stalled at a number the claim cannot be resolved for.
- The deadline is approaching. This one is procedural rather than strategic — the limitations period does not pause while an insurer evaluates a file, so a suit is sometimes filed simply to preserve the claim while negotiation continues.
That last point is the one most people are surprised by. A filed lawsuit is not a declaration that talks have failed. It is often the only way to keep the claim alive past a deadline.
Deadlines That Govern Whether a Lawsuit Can Be Filed
| Type of claim | General deadline | Source |
| Bodily injury against a private party | Two years from the injury | Code Civ. Proc., § 335.1 |
| Damage to a vehicle or other personal property | Three years — longer than the injury deadline | Code Civ. Proc., § 338 |
| Any claim where a public entity may share responsibility | A written claim must be presented to the entity first, on a timeline substantially shorter than two years | California’s Government Claims Act |
| Uninsured or underinsured motorist claim on your own policy | Governed by the insurance statute and your policy, with its own requirements | Ins. Code, § 11580.2 |
Two things worth drawing out. First, the injury and property damage clocks are different lengths, so a vehicle claim can still be viable after the injury claim has expired — which is not much comfort, since the injury claim is usually the substantial one. Second, a uninsured or underinsured motorist claim runs against your own insurer under a contract and does not follow the same rules as a suit against a driver.
The California Courts Self-Help Guide states the general rule plainly: you usually have two years from the date of the injury to sue, and the deadline is shorter if you want to sue a government agency.
Who Can Be Named as a Defendant
The at-fault driver is the obvious defendant and often not the only one. The Courts Self-Help Guide notes that people commonly sue the person who caused the injury, the owner of the vehicle or property, and an employer where the person was working at the time.
Depending on the evidence, others may have a role:
- An employer, where a driver was acting within the scope of employment
- A trucking company or its contractors in a commercial truck collision
- A rideshare driver and, in some circumstances, the platform, in an Uber or Lyft collision
- A vehicle or component manufacturer where a defective product may have failed
- A public entity responsible for a roadway or its maintenance
Identifying defendants early matters for a practical reason beyond liability: it determines which insurance policies are available, and available insurance is frequently the real constraint on what can be recovered.
Which Court Hears the Case
California superior courts divide general civil cases by the amount in controversy. Per the Courts Self-Help Guide, a case for more than $35,000 is filed as an unlimited civil case; a case for $35,000 or less is a limited civil case; and small claims court handles claims up to $12,500 for an individual, without lawyers.
The distinction is not cosmetic. Limited civil cases have restricted discovery and streamlined procedures, which cuts both cost and the tools available to develop a case. Filing a serious injury case as limited to save time can constrain it later.
Venue for a Peninsula collision is generally the San Mateo County Superior Court.
What Happens After a Lawsuit Is Filed
Pleadings
The complaint sets out who is being sued, what happened, and the legal basis for the claim. It is filed with the court, and a summons and complaint are then formally served on each defendant. The defendant — in practice, counsel appointed by their insurer — files a response, usually an answer, and often a set of affirmative defenses including comparative fault.
Discovery
This is the longest phase and where most of the work happens. It typically includes written questions and document demands, depositions of the drivers and often passengers and witnesses, subpoenas for medical and employment records, and frequently a defense medical examination of the plaintiff. Expert witnesses may be retained and deposed.
Discovery is also where the case is actually valued by both sides, because it is where the evidence stops being assertions and becomes testimony and documents.
Settlement efforts
Negotiation continues throughout. Courts commonly direct parties to mediation or a settlement conference before trial. A great many cases resolve at this stage, once both sides have seen the same evidence and the trial date is real.
Trial
If the case does not resolve, it is tried to a judge or jury, who decide fault, apportionment, and damages. Comparatively few filed cases reach this point.
How Long Does It Take?
There is no dependable answer, and figures quoted online are averages across cases with nothing in common. What actually drives the timeline is identifiable: whether liability is contested, how long treatment takes to conclude — a case is difficult to value before the medical picture stabilizes — how many parties and policies are involved, how contested discovery becomes, and the court’s own calendar.
A case where fault is admitted and treatment finished early behaves very differently from one with disputed causation, a defense medical examination, and three defendants. Anyone quoting you a duration without knowing those facts is guessing.
What a Lawsuit Does Not Change
- You still have to prove fault. Filing does not shift the burden.
- Comparative fault still applies. California uses pure comparative fault, so a share of responsibility reduces a recovery rather than barring it — and reducing that share is the defense’s most reliable strategy.
- Insurance limits still constrain recovery. A judgment above the defendant’s policy limits is collectible only to the extent the defendant has assets, which frequently they do not. This is why your own uninsured and underinsured coverage often matters more than the size of a verdict.
- Value is still driven by evidence. Filing does not increase what a claim is worth; it changes the forum in which it is evaluated. How claims are actually valued is covered on our back and neck injury page.

Frequently Asked Questions
It depends on facts nobody can assess from a general description: how clear fault is, what the medical record documents, how much insurance is actually available, and what an insurer has already offered. Filing costs time and involves discovery into your medical history, so it is a decision worth making with advice rather than by default. Where an insurer's position is unreasonable and a deadline is approaching, filing is often the only way to keep the claim alive.
There is no general answer, and no lawyer can predict an outcome. What determines it is evidence: whether fault can be established, whether the collision can be linked to the injuries, and whether the losses are documented. Cases with contemporaneous records and undisputed liability sit very differently from cases with treatment gaps or contested fault.
It varies too widely for an average to mean anything. The main drivers are whether liability is contested, how long treatment takes to conclude, how many parties are involved, how contested discovery becomes, and the court's calendar.
Generally two years from the date of injury under Code of Civil Procedure section 335.1. Property damage carries a longer period under section 338. Where a public entity may share responsibility, a written claim must be presented to that entity first, on a much shorter timeline.
Usually not. Most claims settle without a lawsuit, and most filed cases resolve before trial. You may need to sit for a deposition and attend a mediation or settlement conference, which are not court hearings.
Yes. California uses pure comparative fault, so being partly responsible reduces a recovery by that share rather than barring the claim.
A judgment is only worth what can be collected, and uninsured drivers frequently have no recoverable assets. This is where uninsured and underinsured motorist coverage on your own policy often becomes the more important question.
No. Negotiation typically continues throughout the case, and courts commonly direct parties to mediation or a settlement conference before trial.
