A California personal injury trial follows twelve distinct stages, starting with the complaint and ending with a jury verdict. Most cases resolve before ever reaching that final stage, since discovery, depositions, and mediation give both sides the information they need to negotiate seriously.
When a case does proceed to trial, it typically takes twelve months to three years from filing to verdict, though Los Angeles County’s newer case management rules are compressing that window. Understanding each stage helps clients know what to expect and why their attorneys prepare every case as if a jury will decide it.
Most people picture a personal injury trial as something out of television: dramatic cross-examinations, a tense jury filing back into the courtroom, a verdict read aloud. That moment is real, and it matters. But it’s the last of twelve stages, not the first.
Everything that happens before it determines whether a case is ready to win if it gets there. This guide walks through every stage of a California personal injury lawsuit, from the moment a claim is filed to the possibility of an appeal after verdict, so you know exactly what to expect if your case proceeds down this road.
When Does a Personal Injury Case Go to Trial?
The vast majority of personal injury claims never reach a jury. National and California-specific data both point in the same direction, though the exact percentage varies by source and by how “trial” is defined.
Some estimates put the settlement rate as high as 95 to 97 percent of all personal injury cases. Others, measuring only cases where a formal lawsuit was filed, put the trial rate closer to 3 to 5 percent. Either way, the pattern holds. Settlement is the far more common outcome.
That statistic can create a misleading impression, though. Filing a lawsuit does not mean a case is headed to trial. Litigation itself is not the same thing as trial. Litigation is the broader legal process: filing the complaint, exchanging evidence, taking depositions, and attending mediation. Trial is only the final stage, and it happens when settlement talks fail to produce a fair resolution.
In practice, the discovery and mediation phases of litigation are often what push a case toward a strong settlement.
The value of the case becomes harder to dispute once an insurance carrier sees the:
- Medical records,
- Deposition testimony, and
- Expert opinions an attorney has assembled.
Preparing for trial, in other words, is frequently what makes a favorable settlement possible.
This is why experienced trial lawyers prepare every case as though a jury will ultimately decide it. An attorney who negotiates from a position of trial readiness has more leverage than one who is hoping to avoid the courtroom.
At El Dabe Ritter Trial Lawyers, that principle shapes how a case is built from day one. Insurance adjusters know which firms are prepared to try a case and which are not. And that distinction affects settlement offers long before a jury is ever selected.
Stage 1: Filing the Lawsuit
A personal injury lawsuit formally begins when the plaintiff’s attorney files a Complaint in civil court. The complaint names the defendant, describes the accident and the injuries, and states the legal theories, such as negligence, supporting the claim.
Once filed, the complaint must be formally served on each defendant. Under California Rules of Court, Rule 3.110, the complaint must be served within 60 days of filing. Proof of service must be submitted to the court within that same window. The defendant then has a limited time to respond with an Answer, which admits or denies the allegations and may raise defenses, such as comparative fault.
After the Answer is filed, the court typically schedules an initial case management conference. This sets early deadlines for the case and gives both sides a framework for how litigation will proceed.
Filing a lawsuit is a significant step, but it does not mean the case is headed to trial.
Most lawsuits that are filed still resolve through negotiation, often well before a trial date is ever set.
Filing simply moves the case into a formal legal process with enforceable deadlines, which itself can motivate more serious settlement discussions.
Stage 2: Discovery
Discovery is the formal exchange of evidence between both sides, and it is usually the longest phase of a personal injury lawsuit.
It typically runs from shortly after filing through roughly 30 days before trial. It can take six to twelve months or longer depending on the complexity of the case.
Several tools drive this exchange. Written discovery includes interrogatories, formal written questions that the opposing party must answer under oath, governed in California by Code of Civil Procedure §§ 2030.010 et seq.
Document production requests compel each side to turn over relevant records, including:
- Medical records
- Employment files
- Internal claims files from the insurance carrier
Requests for admission ask the other side to confirm or deny specific facts, narrowing the issues that remain genuinely disputed.
Medical records play an especially central role in personal injury discovery. They establish the nature and extent of the injury, connect it to the accident, and support the damages being claimed.
Expert disclosure typically happens toward the end of discovery, when each side identifies the witnesses, often physicians, accident reconstructionists, or economists, who will testify about causation, injury, or damages at trial.
Discovery is where a case is genuinely built or genuinely tested. An attorney who develops the evidentiary record thoroughly during this phase puts real pressure on the opposing side to negotiate later.
Stage 3: Depositions
A deposition is sworn testimony given outside the courtroom. Usually in an attorney’s office, with a court reporter present to transcribe every word. It is one of the most important tools in discovery because it locks in a witness’s account of events before trial.
Depositions can involve the plaintiff, the defendant, eyewitnesses, treating physicians, and any expert witnesses retained by either side.
Each deposition serves a specific purpose. The plaintiff’s deposition allows the defense to assess credibility and probe the details of the injury and its impact.
Depositions of the defendant and any witnesses help the plaintiff’s attorney evaluate liability and identify inconsistencies that may matter later at trial.
Preparation matters enormously here. An attorney who has not carefully prepared a client for deposition risks allowing inconsistent or poorly framed testimony into the record. Testimony that can be used to challenge credibility months later in front of a jury.
Thorough preparation covers not just what to say, but how to answer difficult questions calmly and accurately under oath.
Depositions matter because they shape everything that follows. Testimony locked in during a deposition becomes the baseline against which trial testimony is measured, and any deviation can be used for impeachment.
Stage 4: Mediation and Settlement Discussions
Once discovery has developed the evidence, most litigated personal injury cases in California move toward mediation rather than trial.
Mediation is a confidential, non-binding negotiation conducted with a neutral third party. This is often a retired judge or an experienced trial attorney, who moves between both sides to narrow the gap between demand and offer.
Arbitration is a related but distinct process. Rather than facilitating negotiation, an arbitrator hears evidence and issues a decision, which may be binding or non-binding depending on what the parties agreed to beforehand.
Settlement conferences, sometimes ordered by the court itself, serve a similar function to mediation but occur under the court’s supervision.
Confidentiality is central to why mediation works. Statements made during mediation are generally protected from later use at trial, which allows both sides to speak candidly about the strengths and weaknesses of their case without fear that a concession will be used against them later.
Many cases resolve at this stage because both sides now have a realistic picture of the evidence, the likely range of a jury verdict, and the cost and risk of proceeding further.
A well-prepared plaintiff, backed by strong discovery and credible expert opinions, is often in a strong negotiating position by the time mediation occurs.

Stage 5: Trial Preparation
When a case does not resolve at mediation, it moves into formal trial preparation. This stage is intensive and detail-driven, even though much of the work happens outside the courtroom and outside the client’s direct view.
Witness preparation ensures that every person who will testify, including the client, understands what to expect and how to present their testimony clearly.
Exhibit organization involves compiling and formatting every document, photograph, medical record, and piece of demonstrative evidence that will be shown to the jury.
Pretrial motions may be filed to resolve legal issues in advance, such as motions to exclude certain evidence or testimony before the jury ever hears it.
Trial strategy is developed and refined throughout this stage, incorporating everything learned during discovery and depositions. Attorneys also review the proposed jury instructions, the specific legal standards the jury will be told to apply when deciding the case, to make sure the trial presentation supports each element that must be proven.
This stage is where a case’s foundation gets tested for the first time under real trial conditions, and thorough preparation here shapes how confidently a case can be presented once trial begins.
Stage 6: Jury Selection (Voir Dire)
Trial formally begins with jury selection, known as voir dire. Attorneys for both sides question a pool of potential jurors to identify bias, personal experiences, or other factors that might affect their ability to evaluate the case fairly.
Both sides can challenge potential jurors in two ways. A challenge for cause removes a juror who has shown a specific bias or conflict of interest. A peremptory challenge allows an attorney to excuse a juror without stating a reason, within certain legal limits. The goal on both sides is to seat a panel capable of weighing the evidence objectively.
A standard California civil jury has twelve members, though Article I, Section 16 of the California Constitution allows the parties to agree to a smaller panel in open court.
Jury selection matters more than many clients expect. The composition of the jury shapes how evidence is received and how persuasive certain arguments will be. Which is why experienced trial attorneys treat voir dire as a critical strategic stage rather than a formality.
Stage 7: Opening Statements
Once the jury is seated, trial begins in earnest with opening statements. Each side presents a roadmap of the case, outlining what the evidence will show and how the facts support their position.
The plaintiff’s attorney typically goes first, since the plaintiff carries the burden of proof. Under CACI No. 200, codified in Evidence Code § 115, a civil plaintiff must persuade the jury that each required element is more likely true than not true.
This is a lower bar than the “beyond a reasonable doubt” standard used in criminal trials, and it means the case does not need to be proven with certainty, only that the evidence tips more clearly in the plaintiff’s favor.
A strong opening statement does more than list facts. It tells a coherent, honest story that helps the jury understand what happened, why it matters, and what the evidence will show as the trial unfolds. Setting realistic expectations early helps jurors follow the evidence as it’s presented over the following days.
Stage 8: Presenting Evidence and Witness Testimony
After opening statements, the plaintiff presents their case first. This is where the evidence developed during discovery is formally introduced to the jury.
Plaintiff witnesses may include the injured person, eyewitnesses to the accident, and treating physicians who can speak to the injury and its ongoing effects.
Medical experts often testify about causation, connecting the accident to the injuries claimed, and about the future medical needs the injury may require. Documents, photographs, and demonstrative evidence, such as diagrams or models, help the jury visualize what happened and understand technical or medical concepts.
Each piece of evidence must be properly introduced and authenticated before the jury can consider it. This is one of the reasons discovery matters so much earlier in the case. Evidence that was not properly developed or preserved during discovery cannot simply be introduced at trial.
Stage 9: Cross-Examination
After each witness testifies, the opposing attorney has the opportunity to cross-examine them. Cross-examination tests the credibility of the testimony just given and probes for inconsistencies, gaps, or weaknesses.
Cross-examination serves several purposes at once. It can:
- Clarify testimony that seemed unclear or incomplete during direct examination.
- Challenge an expert witness’s methodology or conclusions, an especially important function when medical causation or the value of future damages is disputed.
- Highlight prior statements, such as deposition testimony, that conflict with what a witness says on the stand.
Skilled cross-examination is one of the clearest signals of trial experience. It requires careful preparation long before the witness ever takes the stand, built on a thorough understanding of the record developed during discovery and depositions.
Stage 10: Closing Arguments
Once both sides have presented their evidence, each attorney delivers a closing argument. This is the final opportunity to speak directly to the jury before deliberations begin.
A closing argument summarizes the evidence presented over the course of the trial and connects the individual facts into a coherent narrative.
For the plaintiff, this typically means walking the jury through how the evidence satisfies the burden of proof on liability. And then addressing the damages the plaintiff is asking the jury to award (including medical expenses, lost income, and pain and suffering).
Closing arguments also reinforce the applicable legal standard. Reminding the jury that the plaintiff need only show that the claims are more likely true than not true, rather than prove them with certainty, is often central to how the plaintiff’s closing is framed.
Stage 11: Jury Deliberations and Verdict
After closing arguments, the judge reads the jury instructions, the specific legal standards the jury must apply, and the jury retires to deliberate privately.
California civil trials do not require a unanimous verdict. Under Code of Civil Procedure § 618 and Article I, Section 16 of the California Constitution, a verdict is valid once three-fourths of the jury agrees. This means nine of twelve jurors on a standard panel.
This is a meaningfully lower threshold than the unanimous verdict required in criminal trials. It reflects the different stakes involved in civil litigation.
Once the jury reaches a decision, the verdict is read in open court by the foreperson. Either party may request that the jury be polled, a process governed by CACI No. 5017, in which each juror is individually asked whether the verdict reflects their own vote. If the polling reveals that fewer than nine jurors agree, the jury is sent back to deliberate further.
Verdicts can take different forms. A general verdict simply states who wins and, if applicable, the amount of damages. A special verdict requires the jury to answer specific factual questions, which the court then uses to determine the final judgment.
If the jury finds in the plaintiff’s favor, it will also determine the damages owed, taking into account California’s pure comparative negligence rule, which reduces an award in proportion to any fault assigned to the plaintiff.
Stage 12: Appeals (When Applicable)
A trial verdict is not always the final word. Either party may challenge the outcome after trial, though an appeal is a fundamentally different process than the trial itself.
An appeal is not a new trial. The appellate court does not hear new evidence or re-examine witness credibility. Instead, it reviews the trial court record for specific legal errors.
Legal errors can include: an incorrect jury instruction or improperly admitted evidence that may have affected the outcome.
Not every verdict is appealed. Appeals add significant time, often a year or more, and cost to a case.
They are typically pursued only when a party believes a genuine legal error occurred. Not simply because they disagree with the jury’s assessment of the facts.
Many cases that are appealed still settle before the appellate process concludes, once both sides have had time to evaluate the risk of the verdict standing.
Frequently Asked Questions
The trial itself, once it begins, typically lasts anywhere from a few days to several weeks, depending on the number of witnesses and the complexity of the medical and liability issues involved. The larger timeline, from filing the lawsuit to a verdict, commonly runs one to three years in California. However, Los Angeles County’s newer case management rules are working to shorten that window.
No. The substantial majority of personal injury lawsuits settle before trial, most often during discovery or at mediation. Only a small percentage of filed cases proceed all the way to a jury verdict.
A settlement resolves the case by agreement between both sides, without a jury deciding liability or damages. Once a settlement is signed, the lawsuit is dismissed, and the agreed compensation is paid. Typically within a set number of weeks.
Yes. Going to trial does not reduce your right to compensation. If the jury finds in your favor, it will determine the damages owed based on the evidence presented. Subject to California’s comparative negligence rules if any fault is assigned to you.
In most personal injury cases that reach trial, the plaintiff testifies. This is because their firsthand account of the accident and its impact is often central to the case. Your attorney will prepare you thoroughly beforehand so you know what to expect.
Juries are selected through voir dire. It’s a process in which attorneys for both sides question potential jurors to identify bias or conflicts of interest. Jurors can be excused through challenges for cause or peremptory challenges before the final panel is seated.
If the jury finds against you, you may have the option to file post-trial motions. Or pursue an appeal if a genuine legal error affected the outcome. Your attorney can evaluate whether grounds for appeal exist based on what happened during the trial.
Yes. Either the plaintiff or the defendant may appeal a verdict they believe resulted from a legal error. An appeal reviews the trial record for mistakes of law, not the jury’s factual conclusions. And it is a separate process from the trial itself.
A settlement is a negotiated agreement between the parties, reached at any point before or even during trial. Without a jury’s involvement. On the other hand, a verdict is the jury’s formal decision. After hearing all the evidence and deliberating, a verdict is only reached if the case proceeds through a full trial.
Understanding the Process Changes What You Can Do With It
The trial process can seem overwhelming from the outside: twelve stages, unfamiliar terminology, and a timeline that can stretch over years.
Clients rarely need to master every procedural detail themselves. What matters is understanding the shape of the process well enough to make informed decisions at each stage — including when to negotiate and when to hold firm.
At El Dabe Ritter Trial Lawyers, we prepare every case as though it will be tried in front of a jury, whether it ultimately settles at mediation or reaches a verdict. That preparation is what gives clients real leverage. And it’s why understanding this process matters even for the cases that never see a courtroom.
If you’re weighing whether to accept a settlement offer or move forward toward trial, Sherif El Dabe and Jonathan Ritter can walk you through exactly where your case stands and what each path realistically involves.
