Most wrongful death claims in California rest on negligence: someone failed to use reasonable care, and that failure caused a death. What a family has to prove, which deadline applies, and whose insurance may be involved all depend on who was careless. A driver, a business, an employer, a public agency, and a medical provider are each held to different rules.
This guide explains the general standard first, then how it applies to each type of party, how negligence is proven when the person who died cannot tell their side, and how fault is divided when more than one party is responsible.
Under Civil Code section 1714(a), everyone is responsible for injury caused by a lack of ordinary care or skill in managing their property or conduct. A wrongful death negligence claim generally requires showing that a party failed to use reasonable care, that the failure was a substantial factor in causing the death, and that eligible family members suffered losses as a result. Additional rules apply when the party is a vehicle owner, an employer, a public agency, or a health care provider.
Key Takeaways
- Negligence does not require bad intent. Carelessness is enough if it caused the death.
- Businesses can be responsible for their own carelessness and for an employee’s negligence on the job.
- A public agency is liable for dangerous property only under specific statutory conditions, and a written claim generally must be presented within six months.
- When a worker dies on the job, workers’ compensation is generally the remedy against the employer, but claims against other parties remain available.
- Medical negligence claims have their own deadline and a 90-day notice requirement.
- When several parties share fault, each defendant’s share of non-economic damages is generally limited to its own percentage of fault.
What Wrongful Death Negligence Means Under California Law
Code of Civil Procedure section 377.60 allows certain family members to bring a claim for a death caused by the wrongful act or neglect of another. Civil Code section 1714(a) supplies the general duty behind most of those claims: everyone is responsible for injury caused by their want of ordinary care or skill in managing their property or person.
In practice, that becomes four questions:
| Question | What it asks |
|---|---|
| Was care owed? | Did the person or organization have a responsibility to act carefully toward the person who died? |
| Was care lacking? | Did they fall short of what a reasonably careful person or organization would have done? |
| Did that failure cause the death? | Was the carelessness a substantial factor in bringing about the death? |
| What did the family lose? | What losses did the eligible family members suffer because of the death? |
Who counts as an eligible family member is covered in who can file a wrongful death lawsuit.
Individuals: Drivers, Homeowners, and Others
A private person is measured against what a reasonably careful person would have done in the same situation. Two rules often matter:
- Broken safety laws. Under Evidence Code section 669, a failure to use due care is presumed if the person violated a statute, ordinance, or regulation, the violation caused the death, the death was the kind of harm the law was meant to prevent, and the person who died was among those the law was meant to protect. The presumption can be rebutted. See negligence per se.
- Vehicle owners. Vehicle Code section 17150 makes a vehicle’s owner liable for death caused by the negligent operation of the vehicle by someone driving it with the owner’s permission. When that liability rests only on ownership, section 17151 limits it to $15,000 for the death of or injury to one person in one accident, and $30,000 for more than one person. Those limits do not apply where the owner is responsible on another basis, such as the driver acting as the owner’s employee.
When the conduct was also a crime, such as impaired driving, see unlawful death for how the criminal case relates to the family’s claim.
Businesses and Employers
A business can be responsible in two ways:
- For its own carelessness. Examples include unsafe premises, inadequate maintenance, poor training or supervision, or hiring or keeping someone it knew or should have known was unfit for the job.
- For an employee’s or agent’s negligence. Civil Code section 2338 makes a principal responsible to third persons for the negligence of its agent in the transaction of the agency’s business. In practice, an employer can be responsible for an employee’s negligence within the scope of the job.
Depending on the facts, responsible businesses can include employers, property owners and managers, contractors, and trucking carriers. See truck accident wrongful death. When the cause was a product rather than anyone’s carelessness, a different theory may apply; see defective products.
Public Agencies and Dangerous Public Property
Claims against a city, county, transit district, or state agency follow the Government Claims Act rather than the general rules:
- Employee negligence. Government Code section 815.2 makes a public entity liable for injury caused by an employee acting within the scope of employment, where the employee would be liable, unless the employee is immune.
- Dangerous property. Under Government Code section 835, the family generally must establish that the property was in a dangerous condition, that the condition caused the death, and that it created a reasonably foreseeable risk of that kind of injury. They must also show either that an employee’s negligent or wrongful act created the condition, or that the entity had actual or constructive notice of it in time to protect against it.
- Notice. Section 835.2 defines actual and constructive notice. Constructive notice requires that the condition existed long enough, and was obvious enough, that the entity should have discovered it with due care. Evidence about whether a reasonable inspection system would have found it can be considered.
- Trivial risks. Under section 830.2, a condition is not considered dangerous if the court finds the risk was so minor, trivial, or insignificant that no reasonable person would conclude it created a substantial risk of injury.
Before any lawsuit, a written claim relating to a death generally must be presented within six months (Government Code section 911.2). After a written rejection, the suit generally must be filed within six months of the date the notice was delivered or mailed (section 945.6).
Deaths on the Job
When a worker dies in the course of employment, Labor Code section 3602 generally makes workers’ compensation the exclusive remedy of the worker’s dependents against the employer. The statute lists limited exceptions, including a death proximately caused by a willful physical assault by the employer.
Workers’ compensation does not end claims against others. Under Labor Code section 3852, a compensation claim does not affect the right to recover damages from anyone other than the employer. Depending on the facts, that can include a general contractor, an equipment manufacturer, a property owner, or a driver from another company. The employer or its insurer may also seek to recover the compensation it paid from that third party.
Medical Care
When a death is alleged to have resulted from a health care provider’s professional negligence, the question is whether care fell below the professional standard, which usually requires expert review. Two procedural rules stand out:
- Deadline. Under Code of Civil Procedure section 340.5, an action for injury or death against a health care provider must be filed within three years after the date of injury or one year after the injury was discovered or should have been discovered, whichever comes first, subject to limited tolling.
- Notice. Under section 364, the provider must be given at least 90 days’ notice of the intention to file suit. If the notice is served within 90 days of the deadline, the deadline is extended by 90 days from service.
Separate statutory limits apply to certain damages in these cases. See wrongful death and medical malpractice.
Proving Negligence When the Person Who Died Cannot Testify
In an injury case, the injured person usually explains what happened. In a death case, that account is missing, and the other side may be the only living witness. These cases often rely on evidence that does not depend on anyone’s memory:
- Vehicle data. Event data recorders can capture speed, braking, steering, and seatbelt status. Under Vehicle Code section 9951, that data generally cannot be retrieved by anyone other than the registered owner without the owner’s consent or a court order.
- Video and electronic records: surveillance and dashcam video, phone records, and building access logs
- Official findings: collision reports, coroner or medical examiner findings, and workplace safety investigations
- Records: maintenance logs, inspection records, prior complaints, training files, and internal policies
- Independent witnesses and expert analysis: accident reconstruction, engineering, or medical causation opinions
Much of this evidence is held by the other side or by third parties, and some of it is overwritten or discarded on routine schedules. If a party willfully suppresses evidence, Evidence Code section 413 allows the jury to consider that when deciding what inferences to draw.
When More Than One Party Shares the Blame
California follows pure comparative fault. Fault can be divided among several defendants and the person who died. A share of fault attributed to the person who died reduces the family’s recovery by that share; it does not bar the claim.
How damages are collected also depends on the type of damages. Under Civil Code section 1431.2, in a wrongful death action based on comparative fault, each defendant’s liability for non-economic damages, such as loss of love and companionship, is several only. Each defendant is liable only for its own percentage of fault for those damages. That is one reason identifying every responsible party matters.
When the Conduct Was More Than Careless
Ordinary negligence is enough to support a wrongful death claim. When a defendant’s conduct involved malice, oppression, or fraud, Civil Code section 3294 allows punitive damages if proven by clear and convincing evidence. Under California law, punitive damages after a death are pursued through the estate’s survival action rather than the family’s wrongful death claim. See wrongful death vs survival action.
Wrongful Death Negligence Deadlines by Type of Party
| Party involved | General rule | Source |
|---|---|---|
| Private person or business | Lawsuit generally within two years | Code Civ. Proc. § 335.1 |
| Public agency | Written claim generally within six months; after a written rejection, suit generally within six months of the date the notice was delivered or mailed | Gov. Code §§ 911.2, 945.6 |
| Health care provider | Three years from injury or one year from discovery, whichever is first, plus 90 days’ notice before suit | Code Civ. Proc. §§ 340.5, 364 |
The estate’s survival action follows its own deadline. Our wrongful death lawsuit deadlines page covers the public entity rules in detail.

Frequently Asked Questions
Generally, that a party failed to use reasonable care, that the failure was a substantial factor in causing the death, and that eligible family members suffered losses as a result. Civil Code section 1714(a) sets the general duty of ordinary care.
Yes. Vehicle Code section 17150 makes an owner liable for death caused by negligent operation by a driver with the owner's permission. When liability rests only on ownership, section 17151 limits it to $15,000 for one person and $30,000 for more than one person in an accident.
It can be. Civil Code section 2338 makes a principal responsible for an agent's negligence in the transaction of the agency's business, and a business may also be responsible for its own careless hiring, training, or supervision.
No. Liability for dangerous public property depends on the conditions in Government Code section 835, including notice or an employee's role in creating the condition. A written claim generally must be presented within six months.
Generally not. Labor Code section 3602 makes workers' compensation the exclusive remedy against the employer, with limited exceptions. Claims against other responsible parties remain available under Labor Code section 3852.
Not automatically. Under Evidence Code section 669, it can create a presumption of negligence when the law was meant to prevent this kind of harm to this kind of person. The presumption can be rebutted, and causation still has to be shown.
Under California's pure comparative fault rule, the recovery is reduced by the share of fault attributed to the person who died. The claim is not barred.
Not for every type of damages. Under Civil Code section 1431.2, each defendant's liability for non-economic damages is limited to its own percentage of fault. How economic damages are handled depends on the case.
