How Does a Personal Injury Lawsuit Work in California?

Most personal injury cases settle without ever going to trial — but understanding how the litigation process works gives you confidence in the system and helps you make informed decisions. Here is a complete walkthrough of how a California personal injury lawsuit proceeds from filing to resolution.

Phase 1: Pre-Litigation (Before Filing)

Most cases begin with an attempt to settle without filing a lawsuit. Your attorney will:

1. Investigate the accident, gather evidence, and identify all liable parties
2. Help you complete medical treatment and reach maximum medical improvement (MMI)
3. Compile a complete demand package with all medical records, bills, wage loss documentation, and a damages analysis
4. Send a demand letter to the at-fault party's insurer
5. Negotiate toward a settlement

If negotiations fail to produce a fair settlement, your attorney files a lawsuit.

Phase 2: Filing the Complaint

Your attorney files a civil complaint in the appropriate California Superior Court. The complaint names the defendant(s), states the facts of the case, and lists the legal causes of action (typically negligence) and the damages you're seeking.

The defendant is then officially "served" with the complaint and given 30 days to respond. Their response is typically either an Answer (denying liability) or a Demurrer (challenging the legal sufficiency of the complaint).

Phase 3: Discovery

Discovery is the formal process by which both sides exchange information and evidence. This is often the longest phase of litigation. It includes:

• Interrogatories — written questions that must be answered under oath
• Requests for Production (RFP) — demands for documents, records, and evidence
• Requests for Admission (RFA) — requests to admit or deny specific facts
• Depositions — oral testimony under oath, recorded by a court reporter (the most powerful discovery tool)
• Independent Medical Examinations (IME) — the defense may require you to be examined by their own doctor
• Expert witnesses — both sides may designate experts in medicine, accident reconstruction, economics, etc.

Phase 4: Mediation

Most California courts require the parties to attempt mediation before trial. A neutral mediator (typically a retired judge or experienced attorney) facilitates settlement discussions. Mediation is confidential and non-binding — if you don't reach a deal, you proceed to trial.

Phase 5: Pre-Trial Motions

Before trial, both attorneys file motions to shape what evidence the jury will see. Common pre-trial motions include:

• Motion for Summary Judgment — asking the court to dismiss the case (or part of it) without trial because there is no genuine dispute of material fact
• Motions in Limine — requests to exclude certain evidence or arguments at trial (e.g., evidence of prior injuries, insurance status, criminal history)

Phase 6: Trial

California personal injury trials typically last 3–10 days. The process includes:

1. Jury selection (voir dire) — attorneys question potential jurors and exercise challenges
2. Opening statements — each attorney previews their case
3. Plaintiff's case in chief — your attorney presents witnesses and evidence
4. Defendant's case — defense presents their witnesses and evidence
5. Closing arguments
6. Jury deliberation and verdict

In California, personal injury cases require only a 9-3 jury verdict (not unanimous) in civil court.

Phase 7: Post-Trial

After a verdict, the losing party may file post-trial motions (motion for new trial, motion for JNOV) or appeal to the California Court of Appeal. If the defendant loses and doesn't pay, your attorney can enforce the judgment through wage garnishment, bank levies, or property liens.

Typical Timeline

• Pre-litigation settlement: 6 months – 2 years
• Filing to trial: 18 months – 3+ years (California courts are congested)
• Trial through appeal: adds 1–3 more years in contested cases
