​

What Is Negligence in a Wrongful Death Case?

In legal terms, negligence refers to the failure of an individual or entity to exercise reasonable care, resulting in harm to another person. To prevail in a wrongful death case, the plaintiff—typically a surviving spouse, child, or dependent—must prove that the defendant's negligent actions or inactions caused the death.

To establish negligence, you must prove four key elements:

1. Duty of Care: The defendant had a legal responsibility to act with reasonable care toward the deceased.
   
   • In everyday scenarios, this means acting as a reasonable person would—drivers must follow traffic laws, property owners must address hazards, medical professionals must meet accepted standards of care.
   • The specific duty depends on the relationship: driver‑pedestrian, employer‑employee, doctor‑patient, manufacturer‑consumer, etc.
2. Breach of Duty: The defendant failed to uphold that duty through negligent or reckless behavior.
   • Examples include speeding, DUI, ignoring OSHA rules, leaving known hazards unaddressed, misreading medical tests, or manufacturing defective products.
3. Causation: The defendant's actions (or lack of action) directly caused the death. You must tie the breach directly to the death using a “but-for” test: would the death have occurred without (but-for) the defendant's negligence?
   • For example: A driver's DUI caused a fatal crash; a defective guardrail collapsed at a construction site; a surgeon's error led to fatal complications.
   • Expert witnesses—like accident reconstructionists, medical doctors, or engineers—play a crucial role in linking these facts
4. ​Damages: The family suffered measurable harm, such as financial losses or emotional suffering, as a result of the death.
   • Economic damages such as lost income, funeral costs, and medical bills. Documented with pay records, receipts, and expert economic testimony.
   • Non‑economic damages like like loss of companionship and emotional support. Evidence includes testimony from loved ones, life‑expectancy data, and more.

Steps to Prove Negligence in a Wrongful Death Case

​

"In every wrongful death case, our mission is to honor the life lost by uncovering the truth and demanding accountability. Families deserve answers—and we're here to make sure their voices are heard." — Conor Hulburt, Founding Attorney, Hulburt Law Firm

​

1. Gathering Evidence

Evidence is the foundation of any wrongful death case. It serves to establish what happened, who was responsible, and how their negligence caused the death. Key types of evidence include:

• Accident Reports: Police reports, workplace incident records, or other official documentation that details the events leading to the death.
• Photographs or Videos: Visual evidence from the scene, such as skid marks, vehicle damage, unsafe working conditions, or surveillance footage.
• Medical Records: Documentation of the deceased's injuries, treatment, and cause of death can demonstrate how the negligent actions led to the fatal outcome.
• Physical Evidence: Tangible items, such as defective products or damaged equipment, that contributed to the accident.

Experienced San Diego wrongful death attorneys will gather, analyze, and preserve this evidence to build a compelling case.

​

2. Witness Testimony

Witnesses play a vital role in establishing the facts of a wrongful death case. They provide firsthand accounts of what happened and can offer crucial insight into the defendant's actions.

Types of witnesses include:

• Eyewitnesses: People who were present at the scene and can describe the events as they occurred.
• Damages Witnesses: Individuals who can speak to the deceased's life and relationships.
• Expert Witnesses: Professionals with specialized knowledge who can analyze evidence and provide expert opinions (more on this below).

An attorney will work to identify and interview witnesses, ensuring their testimony supports your case.

​

3. Expert Analysis

In many wrongful death cases, expert witnesses are essential for explaining complex issues and demonstrating how negligence occurred. These experts can provide insights that go beyond what lay witnesses or evidence alone can show.

Common types of experts in wrongful death cases include:

• Accident Reconstruction Experts: They use evidence like skid marks, vehicle damage, and traffic patterns to recreate the events of an accident.
• Medical Experts: They explain how the defendant's negligence caused the death, such as in cases of medical malpractice or delayed diagnosis.
• Economic Experts: They calculate the financial losses the family will endure, including lost wages, benefits, and the value of household contributions.
• Engineering Experts: In cases involving defective products or unsafe premises, they can identify design flaws, construction defects, or violations of safety standards.

​

4. Proving Causation

Proving causation—that the defendant's actions directly led to the death—is an important aspect of a wrongful death case. For example:

• In a car accident, this might involve proving that the driver's speeding or drunk driving caused the collision.
• In a product defect case, this involves demonstrating how the product contributed to the injury and death.
• In a medical malpractice case, you may need to show that a doctor's failure to diagnose a condition or a surgical error directly caused the fatal outcome.

Establishing causation often requires a combination of evidence, witness testimony, and expert analysis to draw a clear connection between the defendant's negligence and the tragedy.

​

5. Demonstrating Damages

Finally, the plaintiff must show how the family has been harmed as a result of the wrongful death. Damages can include:

• Economic losses, such as funeral expenses, lost income, and medical bills.
• Non-economic losses, such as loss of love and companionship, and loss of parental guidance.

Economic losses are proven with:

• Financial earnings records (e.g., W-2 Forms, 1099 Forms, etc.)
• Employment benefit records
• Funeral expense receipts
• Expert economist reports and testimony

Non-economic losses are demonstrated with:

• Family photographs and videos from before and after the death
• Testimony of affected family members
• Testimony of friends, family, and colleagues about the decedent and his or her relationships
• Life expectancy tables and medical records
• Arguments of experienced wrongful death counsel

Comparative Fault: What Happens When Multiple Parties Share Blame

California follows a pure comparative negligence system, established in Li v. Yellow Cab Co. (1975) 13 Cal.3d 804. This means a family's wrongful death recovery is reduced by the deceased's percentage of fault—but it is never completely barred, no matter how high that percentage.

For example, if a jury finds that the deceased was 20% at fault for the accident that caused their death, the family's total damages would be reduced by 20%. Under Proposition 51 (California Civil Code § 1431.2), each defendant is liable for their full share of economic damages but only their proportionate share of non-economic damages.

Defense attorneys frequently attempt to shift blame onto the deceased—arguing, for instance, that a pedestrian was jaywalking or that a driver failed to wear a seatbelt. An experienced wrongful death attorney anticipates these arguments and builds the evidence needed to minimize or eliminate any fault attributed to your loved one.

Why Skilled Legal Representation Is Essential

Navigating wrongful death claims in San Diego requires detailed knowledge of applicable laws—like the wrongful death and survival statutes (Code Civ. Proc. §§ 377.60, 377.30)—and proven resources for gathering evidence, hiring experts, and negotiating strategically. California imposes a two-year statute of limitations on wrongful death claims, so acting quickly is essential.
