If you've been injured in an accident in California, one of the most consequential rules you'll encounter is the statute of limitations — the legal deadline by which a personal injury lawsuit must be filed. Missing this deadline generally means losing the right to sue, regardless of how strong the underlying claim might be.
A statute of limitations is a law that sets a time limit on legal action. In personal injury cases, the clock typically starts running from the date of the injury — though California law recognizes important exceptions that can move that start date.
The purpose is practical: evidence fades, witnesses become harder to locate, and memories change over time. Courts and legislatures have decided that at some point, defendants deserve protection from claims that surface years or decades after the fact.
For most personal injury claims in California, the statute of limitations is two years from the date of injury. This applies to common accident types, including motor vehicle crashes, slip-and-fall incidents, and other situations where someone's negligence caused physical harm.
That two-year window applies to filing a lawsuit in civil court — not to reporting an accident, filing an insurance claim, or notifying a government agency. Those processes often have their own separate and sometimes shorter deadlines.
Several exceptions and special rules under California law can shorten or extend that baseline deadline significantly.
Claims against government entities follow a different process entirely. If a city, county, state agency, or other public entity is potentially liable — say, because a road defect contributed to a crash — California law generally requires filing an administrative tort claim within six months of the incident before any lawsuit can be filed. Missing that administrative step can bar the lawsuit altogether.
The discovery rule is one of the more nuanced exceptions. If an injury wasn't immediately apparent — some internal injuries, latent conditions, or harm caused by a product — California courts may allow the limitations period to begin from the date the plaintiff discovered (or reasonably should have discovered) the injury, rather than from the accident itself.
Injured minors are treated differently under California law. The limitations period is generally paused — legally referred to as being "tolled" — while the injured person is under 18. Once they turn 18, the standard period begins to run. However, this tolling has limits that vary by case type.
Mental incapacity at the time of injury may also toll the statute of limitations under certain circumstances.
It's worth separating two distinct processes that often run in parallel:
| Process | Governed By | Typical Timeline |
|---|---|---|
| Insurance claim (first or third party) | Insurance policy terms | Days to months after accident |
| Civil lawsuit | California statute of limitations | Generally 2 years from injury |
| Government entity claim | California Government Claims Act | Often 6 months from incident |
Filing an insurance claim has nothing to do with the lawsuit deadline — but insurance negotiations can drag on long enough to put someone dangerously close to the legal filing deadline without realizing it. A settlement reached with an insurer typically involves releasing future legal claims, so the timing of those conversations matters.
Several situations lead people to approach or miss the deadline without realizing it:
Understanding the deadline matters because personal injury claims in California can potentially recover several categories of compensation:
California does not cap non-economic damages in most personal injury cases (medical malpractice is a notable exception with its own rules). The potential value of a claim, and what categories of damages apply, depends heavily on the specific facts, the severity of injury, and available insurance coverage.
Most personal injury attorneys in California work on a contingency fee basis — meaning they receive a percentage of any recovery rather than charging upfront. One of the first things an attorney evaluates when taking a case is whether the statute of limitations still permits a lawsuit and whether any administrative prerequisites have been met.
Attorneys will often begin tracking the two-year window from day one, while simultaneously pursuing insurance negotiations. If a fair settlement isn't reached, having preserved the right to sue provides important leverage.
California's two-year general rule is a starting point — not a universal answer for every situation. The applicable deadline in a given case depends on:
The facts of an individual accident — who was involved, what caused it, what injuries resulted, and what happened in the days and weeks after — are what determine which version of the deadline actually applies.
