Types of Civil Cases in California

Civil lawsuits in California cover a wide range of disputes between individuals, businesses, or organizations. Unlike criminal cases, which involve violations of penal laws prosecuted by the state, civil cases focus on resolving private conflicts and awarding compensation or equitable relief. Common civil matters include Personal Injury Claims: These arise from accidents or negligence, such as car crashes, slip-and-fall incidents, or medical malpractice, where the plaintiff seeks compensation for injuries and damages. Breach of Contract: Disputes occur when one party fails to fulfill contractual obligations, whether in business agreements, service contracts, or real estate transactions.

California Court Jurisdiction Based on Claim Amount

California’s court system divides civil cases into three tiers based on the monetary value of the claim, ensuring efficient resolution. Limited Civil Lawsuit Cases: For claims between $10, 000 an d$ 25,000, heard in Superior Court. These cases follow formal rules but have streamlined procedures, such as limited discovery. Common examples include larger contract disputes or moderate personal injury claims. Unlimited Civil Cases: Involves claims exceeding $25,000 or requests for non-monetary relief (e.g., injunctions). These cases follow full legal procedures, including extensive discovery and potential jury trials. Major lawsuits, like significant personal injury or complex business litigation, fall here.

Determine Whether You Have a Valid Claim

Before filing a lawsuit, assess whether your case has legal merit. Ask yourself Do you have a legally recognized right that was violated? Can you prove that the defendant caused your damages? Is there sufficient evidence to support your claim? If the answer to these questions is yes, you may proceed. However, if your claim is weak or lacks evidence, you risk losing the case and potentially paying the defendant’s legal fees. Consulting an attorney at this stage can help evaluate your claim’s strength.

Attempt to Resolve the Dispute Out of Court

California courts encourage parties to settle disputes before filing a lawsuit. Methods like mediation, arbitration, or direct negotiation can save time and Civil Lawsuit costs. If an agreement is reached, you can draft a settlement contract instead of going to court. However, if negotiations fail, proceed with filing the lawsuit.

Facts of the case Provide a clear, chronological account of what happened. Request for relief Specify what you’re asking for (monetary damages, injunctions, etc.). Once drafted, file the complaint with the appropriate court and pay the filing fee (typically $435 for unlimited civil cases, though fee waivers are available for low-income filers).

Serve the Defendant Properly

After filing, you must serve the defendant with a copy of the complaint and a summons.

Service by Publication If the defendant can’t be found, you may publish a notice in a newspaper (requires court approval). You must then file a Proof of Service form with the court to confirm delivery.

Await the Defendant’s Response

The defendant has 30 days (from the date of service) to respond. They may File an Answer Admitting or denying your allegations. File a Demurrer Challenging the legal sufficiency of your Civil Lawsuit. File a Motion to Strike Asking the court to remove certain claims. File a Cross-Complaint Suing you in return. If the defendant doesn’t respond, you can request a default judgment in your favor.

Discovery Phase

Both parties exchange evidence through Interrogatories (written questions). Depositions (recorded witness testimonies). Requests for Production (demands for documents). Requests for Admission (asking the other side to admit facts). Discovery helps strengthen your case before trial.

Pre-Trial Motions and Settlement Negotiations

Before trial, either party may file motions (e.g., summary judgment to dismiss part of the case). Many cases settle during this phase through negotiation or mediation.

Trial and Judgment

If no settlement is reached, the case proceeds to trial. Both sides present evidence, call witnesses, and make arguments. The judge (or jury) then issues a verdict. If you Civil Lawsuit, the court will enter a judgment in your favor, which may include monetary damages or other relief.

Post-Trial Actions
