How Long Does a Personal Injury Lawsuit Take in California?

A California personal injury lawsuit moves through predictable procedural stages from complaint filing to trial — but the timeline varies significantly by county, case complexity, and whether the case settles before reaching trial. Most California personal injury cases settle before trial, making the question of timeline partly a question of when during the litigation process settlement becomes achievable.

The Pre-Suit Phase

Before a lawsuit is filed, most personal injury cases go through an insurance claims process. The injured party (often through their attorney) submits a demand package to the at-fault driver's insurer, the insurer responds with an offer, and negotiation begins. This pre-suit process can take anywhere from a few months to more than a year, depending on the complexity of the injuries and the insurer's responsiveness.

The pre-suit phase should not begin until the injured party has reached maximum medical improvement (MMI) — the point at which their treating physician believes the condition has stabilized and future care needs can be projected. Settling before MMI risks undervaluing future medical costs and earning capacity losses.

If pre-suit negotiations fail to produce an adequate settlement, the next step is filing a lawsuit before the applicable statute of limitations expires. California's standard personal injury statute of limitations under CCP section 335.1 is two years from the date of injury, creating the outer deadline that drives the filing decision when negotiations stall.

Filing the Complaint

Filing a personal injury complaint formally initiates the lawsuit. The defendant is served with the complaint and summons, typically within 60 days of filing, and has 30 days to file a response (Answer). Some defendants file demurrers — threshold legal challenges — which add additional briefing cycles before the answer is filed.

Shortly after the answer is filed, the court schedules a Case Management Conference (CMC) — typically 90 to 120 days after filing. At the CMC, the court sets the case schedule: discovery cut-off dates, expert designation deadlines, mandatory settlement conference date, and trial date.

The trial date set at the CMC is typically 18 to 30 months from the date of filing in San Diego and Sacramento, 18 to 24 months in Fresno (faster docket), and 2 to 4 years in Los Angeles County (larger docket). San Francisco falls in the 18 to 30 month range.

Discovery

Discovery is the pre-trial information-exchange process that typically consumes the majority of the litigation timeline between filing and trial. California civil discovery tools include:

• Interrogatories — written questions answered under oath by each party
• Requests for Production — demands for documents, records, photos, videos, and electronically stored information
• Requests for Admission — requests to admit or deny specific facts to narrow the contested issues at trial
• Depositions — sworn testimony taken before a court reporter, outside court, from parties and witnesses
• Defense medical examination (DME) — the defense's right to have the plaintiff examined by their own physician, whose findings often contradict the treating physician's conclusions

The discovery cut-off is typically set 30 to 60 days before the trial date. All discovery must be completed before that deadline. Depositions of key parties — the plaintiff, the defendant driver, eyewitnesses, treating physicians, and potentially the defendant's insurer's representatives in bad faith cases — consume most of the discovery period.

Disputes over discovery responses generate motion practice that can add months to the timeline. Common discovery disputes include the defendant's refusal to produce insurance policy information, disputes about the scope of the plaintiff's medical records production, and defense attempts to obtain broad social media access.

Expert Witnesses and Designation

California Code of Civil Procedure section 2034 governs expert witness disclosure. Both parties must simultaneously exchange lists of their retained expert witnesses by the expert designation deadline, typically set 50 to 70 days before trial. After designation, each side may depose the other's experts, adding depositions during the final pre-trial period.

In a serious personal injury case, the plaintiff's expert witness team typically includes: a treating physician to testify on causation and injury severity; a life care planner to project future medical costs; a vocational rehabilitation expert to assess earning capacity loss; an accident reconstruction expert if liability is disputed; and potentially an economist to calculate present value of future economic losses. Defense experts present competing opinions on each of these issues.

Pre-Trial Motions

As the trial date approaches, both parties may file pre-trial motions that affect the scope of trial. Common pre-trial motions in California personal injury cases include:

Motions in limine — motions to exclude specific evidence or arguments from trial. These are decided by the trial judge and shape what the jury will hear. Common subjects include: exclusion of prior accidents, exclusion of insurance coverage evidence, limits on expert testimony scope, and exclusion of prejudicial photographs.

Summary judgment motions — requests that the court rule in favor of one party as a matter of law without a trial because no genuine dispute of material fact exists. In personal injury cases, defendants file summary judgment motions arguing that no duty existed, that the defendant was not negligent, or that the plaintiff cannot prove causation. Successfully opposing summary judgment is often a significant pre-trial milestone.

Mandatory Settlement Conference

California courts require a mandatory settlement conference (MSC) typically 2 to 4 weeks before the trial date. The MSC is conducted by a judicial officer (a judge or experienced attorney serving as a settlement officer) who evaluates the case and facilitates settlement discussions. Parties are required to attend in person.

The MSC resolves a significant share of California personal injury cases. Having a neutral judicial officer evaluate the liability and damages evidence — and communicate their assessment to both sides — frequently produces settlements that negotiation alone could not achieve. The MSC is the final major settlement opportunity before trial begins.

Trial

If the case does not settle before or at the MSC, it proceeds to jury trial. Personal injury trials in California typically run 3 to 10 court days, though complex multi-defendant cases can run longer. The trial process includes jury selection (voir dire), opening statements, plaintiff's case-in-chief (testimony, documents, exhibits), defense case, rebuttal, closing arguments, and jury deliberations.

After the jury returns a verdict, post-trial motions — motions for new trial, motions to reduce the verdict (remittitur), and motions challenging the award — can add additional months before a final judgment is entered. Appeals further extend the timeline if the losing party has grounds to challenge the trial court's rulings.

Timelines by California County

Trial timelines vary significantly across California's 58 counties. Approximate filing-to-trial timelines for the counties covered on this site:

• Fresno County: 12 to 18 months — fastest major California court
• Sacramento County: 18 to 24 months
• San Diego County: 18 to 30 months
• Santa Clara County (San Jose): 18 to 24 months
• San Francisco County: 18 to 30 months
• Los Angeles County: 24 to 48 months — longest major California court due to docket size

These are general estimates based on current docket conditions and will vary depending on the complexity of the specific case, the availability of judges and courtrooms, and court administrative factors. The COVID-19 backlog has extended timelines in some California courts beyond pre-pandemic norms.
