To file a vicarious liability complaint in California, you draft a fact-specific pleading that sets out the agent’s underlying tort, the relationship that makes the principal legally responsible, and the connection between the two, then file it in the proper superior court with a Civil Case Cover Sheet, a summons, and the current filing fee, and serve each named defendant. California is a fact-pleading state, so labels like “respondeat superior” do no work on their own. Every element needs concrete facts behind it, and the filing fee for an unlimited civil case is $435 as of 2026,1Judicial Branch of California. Statewide Civil Fee Schedule Effective 01/01/2026 which is reason enough to get the pleading right the first time.
Confirm You Still Have Time to Sue
For personal injury claims, the usual vicarious liability setting, California gives you two years from the date of injury.2California Legislative Information. California Code CCP 335.1 Fraud carries a three-year window measured from when you discovered or should have discovered the misrepresentation. If a government entity is the principal, you generally must file an administrative claim within six months of the incident before you can file suit at all. Miss these windows and the strength of your facts stops mattering.
Where to File and Who to Name
Most vicarious liability claims with meaningful damages belong in the superior court of the appropriate county. The default venue rule places the case in the county where the defendant resides when the action begins,3California Legislative Information. California Code CCP 395 though the county where the events happened is also typically proper.4California Courts. Jurisdiction and Venue: Where to File a Case When the principal is a corporation, its county of principal office or the county where the tort occurred both work.
Name both the principal and the agent in the caption. If you do not yet know the agent’s real name, California lets you designate “Doe” defendants, so long as you state in the complaint that you are genuinely ignorant of the person’s identity.5California Legislative Information. California Code CCP 474 Once you learn the name through investigation or discovery, you amend to substitute it in. Courts reject Doe amendments where the plaintiff clearly knew the identity when the case was filed.
Forms, Fees, and Formatting
Every civil case needs a Civil Case Cover Sheet (form CM-010) with the first paper filed.6Judicial Branch of California. California Rules of Court Rule 3.220 – Case Cover Sheet The clerk issues a summons for service on each defendant. The unlimited civil filing fee is $435, with slightly higher fees in Riverside, San Bernardino, and San Francisco counties because of local courthouse construction surcharges.1Judicial Branch of California. Statewide Civil Fee Schedule Effective 01/01/2026 Fee waivers are available for plaintiffs who qualify based on income.
Judicial Council pre-printed complaint forms exist for some straightforward claims, but vicarious liability pleadings generally need custom drafting because the fact-specific allegations do not fit into check-the-box forms.7California Courts. Find and Fill Out Court Forms Documents you draft yourself must follow the formatting rules beginning at California Rules of Court Rule 2.100.
The Fact-Pleading Standard
California requires every complaint to contain “a statement of the facts constituting the cause of action, in ordinary and concise language.”8California Legislative Information. California Code CCP 425.10 That is a higher bar than the federal notice-pleading standard. Each element of each claim needs factual support: who did what, when, where, and how it caused harm. For a vicarious liability complaint, that means facts showing the relationship, the scope of the agent’s authority, the agent’s wrongful conduct, and the link between the two. If the underlying tort involves fraud, the complaint must also identify the particular false statement, who made it, how it was communicated, why the plaintiff relied, and what damage followed.
Plead the Underlying Tort First
Vicarious liability is derivative. If the agent committed no tort, the principal has nothing to answer for. The complaint has to establish a complete cause of action against the agent before connecting it to the principal.
For negligence, the complaint needs facts showing four elements: duty of care owed to the plaintiff, breach of that duty through specific conduct, causation, and actual damages. Describe what the agent did or failed to do rather than asserting that the agent “was negligent.” A delivery driver running a red light while making a company delivery is the kind of concrete allegation California requires.
If the underlying tort is intentional, such as battery, fraud, or conversion, the complaint must allege the mental-state elements those torts require. Factual detail matters more here because the course-and-scope analysis for intentional acts is harder to carry; the pleading needs to show how the conduct grew out of the agent’s job duties rather than purely personal motivation.
Drafting the Respondeat Superior Cause of Action
California Civil Code Section 2338 holds a principal responsible for the negligence of an agent committed during the agent’s handling of the principal’s business, including wrongful acts carried out as part of that business.9California Legislative Information. California Civil Code 2338 – Responsibility of Principal for Agents Negligence or Omission Building this cause of action takes three moves.
First, allege the existence and nature of the employment or agency relationship. State that the agent was employed by or acting on behalf of the principal and describe the general nature of the agent’s duties. Second, allege that the agent was acting within the course and scope of employment when the tort occurred. Conduct falls within that scope under California law if it is reasonably related to the kinds of tasks the employee was hired to perform, or if it was reasonably foreseeable given the employer’s business. Third, incorporate by reference the factual allegations from the underlying tort cause of action, linking the agent’s specific conduct to the principal’s responsibility without repeating every fact.
Course and scope is where complaints most often fail. Vague assertions that the employee “was on the job” will not survive a demurrer. Describe what business activity the employee was engaged in, how it related to assigned duties, and why the employer could reasonably foresee that type of conduct.
Vehicle Owner Liability Under Vehicle Code Section 17150
Vehicle Code Section 17150 makes every owner of a motor vehicle liable for death, injury, or property damage caused by anyone operating the vehicle with the owner’s permission.10California Legislative Information. California Vehicle Code 17150 Permission can be express or implied, and the statute applies whether or not the driver was conducting the owner’s business.
This reaches further than respondeat superior. A friend borrowing your car for personal errands triggers owner liability if the friend drives negligently; no employment relationship or scope-of-employment showing is required. The complaint should allege that the defendant owned the vehicle, that the driver had the owner’s permission to use it, and that the driver’s negligent operation caused the plaintiff’s injuries. It is a useful claim in ride-share situations, company fleet cases, and any accident involving a borrowed vehicle.
Other Relationships That Trigger Vicarious Liability
Joint Ventures and Partnerships
California holds joint venturers and partners vicariously liable for torts committed in furtherance of the shared enterprise. To plead it, allege facts establishing the venture itself: the parties combined resources or expertise for a single business undertaking, each held an ownership interest, they shared control over operations, and they agreed to share profits and losses. Then connect the tortious act to the venture’s business. A tort committed entirely outside the venture’s scope will not pull the other partner in.
Parental Liability for a Minor
Two statutes operate here, each with its own trigger and its own ceiling. Civil Code Section 1714.1 holds a parent with custody and control jointly and severally liable for a minor’s willful misconduct causing injury, death, or property damage, capped at $25,000 per tort (subject to biennial cost-of-living adjustments by the Judicial Council).11California Legislative Information. California Code CIV 1714.1 For personal injuries, the cap covers medical, dental, and hospital expenses. Vehicle Code Section 17707 separately makes parents jointly and severally liable, with no comparable dollar cap, when a minor drives with the parent’s express or implied permission and causes injury through negligent or wrongful driving.12California Legislative Information. California Vehicle Code 17707 Specify which statute applies and plead the particular facts that trigger it: whether the parent gave driving permission, signed the minor’s license application, or had custody and control when the willful misconduct occurred.
Add a Negligent Hiring Claim as a Companion
Plaintiffs often pair respondeat superior with a direct negligence claim against the employer for negligent hiring, supervision, or retention. The two theories cover different ground. If the employer defeats respondeat superior by showing the employee was outside the scope of employment, a negligent hiring claim can still hold the employer directly liable for its own failure to exercise reasonable care.
Negligent hiring requires facts showing the employer hired someone unfit or incompetent for the job, that the employer knew or should have known about the unfitness, that the unfitness created a foreseeable risk to others, and that the employer’s negligence in hiring, supervising, or retaining the employee was a substantial factor in causing harm. A trucking company that hires a driver with multiple DUI convictions and no valid commercial license is on the hook directly when that driver causes a crash, even if the driver was off-route. Put these allegations in a separate cause of action from the respondeat superior claim. Describe what the employer knew or should have discovered through reasonable investigation, what it failed to do, and how that failure connects to the harm.
Plead Around the Defenses You Will See
The Independent Contractor Defense
The most common response to a respondeat superior claim is that the person who caused the harm was an independent contractor. California uses the ABC test under Labor Code Section 2775, and the burden sits with the hiring entity to prove all three prongs: the worker was free from the company’s control and direction in performing the work, the work fell outside the company’s usual course of business, and the worker was customarily engaged in an independently established trade or business of the same nature.13California Legislative Information. California Labor Code 2775 Fail any single prong and the worker is presumed to be an employee.
Preempt this in the complaint by alleging facts that cut against the independent contractor argument: the company set the worker’s schedule, provided equipment, controlled how the work was done, or the work was central to the company’s core business. Locking these facts in early forces the defense to engage with them from the start.
Frolic Versus Detour
Even when the defendant concedes an employment relationship, expect an argument that the employee was on a “frolic,” a major departure from job duties for personal purposes, rather than a “detour,” a minor deviation that still falls within the scope of employment. An employee making a brief personal stop while running a company errand is on a detour, and the employer remains liable. An employee who abandons the errand to handle personal business is on a frolic, and vicarious liability drops away. Allege facts showing the employee’s conduct stayed connected to the work, even if there was some deviation. Describing what the employee was supposed to be doing and how the tortious conduct grew out of those duties makes a frolic defense harder to sustain.
How to Plead Damages
In personal injury and wrongful death cases, California prohibits stating the dollar amount of damages sought in the complaint.8California Legislative Information. California Code CCP 425.10 Allege the categories of harm instead: medical expenses, lost wages, pain and suffering, property damage, loss of earning capacity. Demand judgment “according to proof” or “in an amount to be proven at trial.” For non-personal-injury claims, state the specific amount demanded.
The damages section usually appears in each cause of action or in a general damages paragraph that every cause of action incorporates by reference. Make clear that the principal’s liability extends to the full scope of damages caused by the agent’s tort. If you plan to seek punitive damages against the agent for intentional misconduct, note that punitive damages generally do not transfer vicariously to the employer unless the employer authorized or ratified the conduct, or the agent held a managerial role.
Serving the Complaint
Filing with the court does not put the defendants on notice. Service of process does. California prefers personal delivery of the summons and complaint to each defendant: handing the documents directly to an individual, or delivering them to an officer, general manager, or designated agent for service of process when the defendant is a business entity. If personal service fails after reasonable diligence, substituted service and service by mail are available as alternatives.
Each defendant must be served separately, and you file a proof of service for each. Professional process servers handle this routinely, typically charging between $50 and $200 per service, higher if the defendant is hard to locate. The defendant’s response clock, generally 30 days, starts when service is completed, not when you file. Failing to serve all named defendants promptly can stall the case and, in some situations, lead to dismissal for failure to prosecute.
