California Personal Injury Statute of Limitations: Deadlines, Exceptions, and How Long You Have to File

The california personal injury statute of limitations is the legal deadline for filing a personal injury lawsuit in a California court, and it is usually two years from the injury date. The clock often starts on the accident day, such as a rear-end crash on I-5 in Sacramento, a slip-and-fall inside a grocery store in San Diego, or a dog bite in a Los Angeles neighborhood. A missed deadline can result in a case dismissal even when liability and medical records are strong. Some claims have shorter timelines and different notice rules, especially when a public entity is involved. For example, injuries caused by a city bus, a dangerous sidewalk maintained by a county, or a fall at a public school can trigger a government claim requirement that is commonly due within six months, before any lawsuit is filed. Certain exceptions can extend or shift the filing date. The discovery rule can delay the start when the injury or its cause was not reasonably knowable right away, such as symptoms emerging weeks after a crash or a latent injury discovered after follow-up imaging. Tolling can apply when the injured person is a minor or lacks legal capacity, which can change the final filing date. Different deadlines can also apply to medical malpractice, where a common rule is three years from injury or one year from discovery, depending on the facts. These technical differences matter because the correct deadline depends on the defendant, the injury type, and the exact event timeline documented in reports, medical charts, and claim notices.

California’s Baseline Deadline: 2 Years for Most Injury Lawsuits

Personal injury cases in California are usually governed by a two-year filing deadline that runs from the date the injury occurred. This deadline is set by statute and can end a case regardless of fault if you file late.
California Code of Civil Procedure § 335.1 provides a two-year limitations period for an “action for assault, battery, or injury to, or for the death of, an individual caused by the wrongful act or neglect of another.” In everyday terms, that two-year window typically covers claims arising from events like car crashes, unsafe property conditions, dog bites, and other negligence-based injuries.

Key points that determine the start date:

• Accident-date start is the default (e.g., collision date, bite date, fall date).
• Later “discovery” start can apply when the injury or its cause was not reasonably knowable earlier (discussed below).
• Multiple potential defendants can mean multiple timing rules, especially when a public entity is involved.

Government Claims: The 6-Month Trap That Comes Before the Lawsuit

If a city, county, school district, transit agency, or other public entity may be responsible, you commonly must file an administrative claim within six months before you can sue. Missing this step can bar the case even if you still have time under the two-year court deadline.
The California Government Claims Act (Gov. Code §§ 810–996.6) generally requires a written claim for personal injury or wrongful death to be presented to the public entity no later than six months after the accrual of the cause of action. (Gov. Code § 911.2.)

Common scenarios that trigger the government-claim process:

• Crash involving a city bus or public transit vehicle.
• Trip-and-fall from a dangerous sidewalk, pothole, or roadway defect maintained by a public entity.
• Injury on public school property or during a school-related activity.
• Negligence by public employees acting within the scope of employment.

How the process typically works in practice:

1. Present the claim to the correct public entity (not the individual employee).
2. Wait for acceptance/denial (or passage of statutory response time).
3. File suit within the post-denial deadline that applies under Gov. Code § 945.6, which is commonly six months from a written notice of rejection for court action against the entity.

For transit-related injuries, see the public transport accident service page for the types of incidents and defendants that commonly bring these notice rules into play.

Medical Malpractice Has Its Own Clock (And It’s Often Shorter Than People Think)

California medical negligence claims operate under a specialized statute that can cut off claims earlier than the general two-year period. The operative rule is three years from injury or one year from discovery, whichever occurs first, subject to defined exceptions.
Code of Civil Procedure § 340.5 governs actions against health care providers based on professional negligence. The statute generally requires filing:

• Within 3 years after the date of injury, or
• Within 1 year after the plaintiff discovers (or should have discovered) the injury,
• Whichever occurs first.

Legally recognized exceptions under § 340.5 can matter:

• Fraud or intentional concealment.
• Presence of a foreign body left inside the patient (with statutory nuances).
• Minors have special rules depending on age and circumstances.

Because malpractice limitations can be fact-intensive (injury date vs. discovery date vs. last negligent act), the safest practice is to map dates directly from the medical chart, imaging timeline, and provider communications.

The Discovery Rule: When the Clock Starts Later Than the Accident Date

California law can delay “accrual” when a reasonable person would not have discovered the injury or its negligent cause earlier. This does not create unlimited time; it shifts the start date based on reasonable discoverability.
Courts apply the discovery rule in appropriate cases to prevent technical forfeiture where harm is latent or causation is not immediately apparent. In a personal injury setting, this is most commonly argued when:

• Symptoms appear days or weeks after a crash (e.g., concussion, disc injury identified on later MRI).
• A toxic exposure or product issue causes delayed-onset injury.
• A person knows they are hurt but cannot reasonably know the cause or who caused it until later.

Evidence that typically supports or defeats a “late discovery” argument:

• ER and urgent care records showing initial symptoms (or lack of symptoms).
• Follow-up imaging dates (MRI/CT) and the first documented diagnosis.
• Work restrictions, PT notes, and specialist referrals that show when the condition became apparent.
• Prior similar injuries that may affect what a “reasonable person” should suspect.

Tolling: When the Deadline Pauses Because of Legal Disability

Certain conditions “toll” (pause) the statute of limitations, meaning time does not run for a period recognized by law. Tolling is common for minors and can also apply for lack of legal capacity.
Under Code of Civil Procedure § 352(a), if a person is under 18 or lacks legal capacity at the time the cause of action accrues, the statute of limitations is tolled while the disability exists (subject to exceptions and special statutes).

Practical tolling examples:

• Minor injured in a crash: the two-year clock often does not start running until the 18th birthday (but government-claim rules and other statutes can complicate this—do not assume tolling cures a missed public-entity claim).
• Adult lacking capacity: tolling can apply, but proof is required and disputes are common.

Important limitation:

• Tolling is not a universal fix. Special statutes (including certain claims processes) can override general tolling assumptions, so deadlines must be checked against the specific cause of action and defendant category.

Wrongful Death vs. Survival Actions: Similar Timelines, Different Claims

After a death, California law separates the family’s wrongful death claim from the estate’s survival claim, and each has distinct elements even when they arise from the same incident. Timing mistakes happen when families assume one filing covers everything.
Wrongful death is generally governed by the same two-year statute in Code of Civil Procedure § 335.1, typically running from the date of death (not necessarily the date of injury). Survival claims are brought by the estate representative under Code of Civil Procedure § 377.30 and related sections, and the applicable limitation period tracks the underlying injury claim, with additional procedural requirements.

Checklist to prevent omissions:

• Identify all heirs with standing (wrongful death plaintiffs).
• Open an estate or confirm the proper successor-in-interest procedure for a survival action.
• Calendar the deadline from the correct triggering date (death vs. injury vs. discovery).

How to Protect Your Deadline: A Practical Filing-Readiness Checklist

Most statute problems are preventable if you build a date-driven case file early and identify every potentially responsible party. The goal is to create a “proof packet” that supports accrual, notice compliance, and damages while time remains to correct mistakes.
Use this step-by-step checklist to reduce deadline risk:

1. Write down the full timeline: incident date/time, first symptoms, first treatment, missed work dates, follow-up diagnosis dates.
2. Identify all defendants: driver, employer (respondeat superior), property owner/tenant/manager, product maker, public entity, contractor.
3. Pull official documents:
   • Traffic collision report number and agency (CHP, city PD, sheriff).
   • Incident reports from stores, apartments, or workplaces.
   • Photos/video and witness contact details.
4. Confirm insurance layers: auto liability, umbrella, rideshare coverage, commercial policies, premises policies, UM/UIM.
5. Screen for special rules:
   • Any public entity involvement (bus, road, sidewalk, school, county hospital).
   • Any healthcare-provider negligence (possible § 340.5).
   • Minor or incapacity tolling issues.
6. Calendar multiple dates: the earliest plausible deadline is the operative one until proven otherwise.

If you want a structured action plan immediately after a crash, see after an auto accident, the steps you need to take for documentation steps that also help preserve statute-of-limitations arguments.

Why These Deadlines Are Strict: Courts Enforce Them Even in Strong Liability Cases

Statutes of limitations and claim presentation rules are designed as procedural cutoffs, not “fairness” tests, and courts routinely dismiss untimely cases. Waiting to “see how you heal” is a common reason people lose otherwise valid claims.
What typically causes missed deadlines:

• Delayed treatment and delayed diagnosis without calendaring the last day to sue.
• Unrecognized public-entity involvement (e.g., the road defect is controlled by the city, not the HOA).
• Assuming insurance negotiations stop the clock (they usually do not).
• Confusing workers’ compensation with third-party liability (separate systems; third-party claims still have civil deadlines).

A personal injury case is typically built and presented by a personal injury lawyer through evidence development, demand practice, and—when necessary—court filing before the statutory cutoff.

Deadline-Safe Next Steps: Build the Record While You Still Have Options

The most reliable way to preserve rights is to treat the earliest potential deadline as controlling until you confirm otherwise. Accurate timelines, correct defendant identification, and proper government notice are the three most common make-or-break factors.
Action items that directly protect your ability to file:

• Get a complete copy of your medical records and note the first date each symptom was recorded.
• Document injury progression with dated photos and a pain/function journal.
• Request and preserve video quickly (many systems overwrite within days or weeks).
• Confirm property and roadway control (city/county/state/private) before assuming no government claim is needed.
• Do not rely on adjuster assurances; settlement talks do not extend statutory deadlines unless a legally valid tolling agreement is executed.

Bottom Line: Know the Trigger Date, Identify the Defendant Type, Calendar the Earliest Deadline

California personal injury timing is not one-size-fits-all: most cases are two years, public entity cases often require a six-month claim first, and medical negligence follows CCP § 340.5. The correct deadline is determined by accrual rules, discovery principles, and tolling—applied to a documented event timeline.
If you treat the timeline as a legal element of the case—not a clerical detail—you reduce the risk of dismissal and preserve leverage for negotiation or litigation. The safest approach is to build a date-anchored file early, confirm whether any public entity is involved, and act as though the earliest plausible cutoff is the one the court will enforce.

Don’t Let a Deadline Quietly Kill Your Case—Get Your Dates Checked Now

California injury cases don’t usually fall apart because the other side “wins.” They fall apart because someone missed a date, filed the wrong document, served the wrong entity, or assumed an insurance adjuster’s timeline mattered. That’s how strong liability, clear medical records, and real damages still end in a dismissal.

The operational risk is simple: if you guess wrong on the trigger date, discovery rule, tolling, or whether a public entity is involved, you can lose your right to recover—permanently. Public entity cases can require a government claim in as little as six months, and medical malpractice can be cut off by a one-year discovery deadline even when you’re still treating. Meanwhile, video gets overwritten, witnesses disappear, and the “who owns this roadway/sidewalk/property?” question becomes harder to prove every week you wait.

If you want to protect your claim, you need a local team that will (1) lock in the correct defendant list, (2) map the timeline from records—not memory, and (3) calendar the earliest possible deadline as the real one until proven otherwise. That’s how you keep leverage, keep options, and keep the courthouse doors open.
