What Is Tort Law? Negligence, Liability, and Damages Explained

What Is Tort Law?

A tort is a civil wrong — an act or omission that causes harm to another person and gives rise to a legal claim for compensation. Tort law is the body of law that defines these wrongs and determines who must pay for resulting injuries. Unlike criminal law, which punishes offenders on behalf of society, tort law focuses on compensating victims for losses they have suffered.

Tort claims are litigated in civil court, where the standard of proof is the preponderance of the evidence (more likely than not) rather than the criminal standard of beyond a reasonable doubt. A defendant may face both criminal prosecution and a separate civil tort suit arising from the same conduct, as occurred in several high-profile cases in the United States.

The Three Main Categories of Torts

Negligence: The Most Common Tort

Negligence is by far the most frequently litigated tort. To succeed in a negligence claim, a plaintiff must prove four elements:

1. Duty: The defendant owed the plaintiff a legal duty of care. Drivers owe a duty of reasonable care to other road users; doctors owe a duty of care to patients.
2. Breach: The defendant breached that duty by failing to act as a reasonably prudent person would under similar circumstances.
3. Causation: The breach actually caused the plaintiff's injury (actual causation, or cause-in-fact) and the harm was a foreseeable result of the breach (proximate causation).
4. Damages: The plaintiff suffered actual, measurable harm — physical injury, financial loss, or in some cases emotional distress.

If any element is missing, the negligence claim fails. A defendant who breached a duty of care but caused no actual harm cannot be held liable in negligence.

Standards of Care in Negligence

The benchmark for evaluating conduct is the reasonable person standard: what would a hypothetical reasonable person have done under the same circumstances? This objective standard varies based on context:

• Professionals (doctors, lawyers, engineers) are held to the standard of a reasonable professional in their field, not merely a reasonable layperson
• Children are held to the standard of a reasonable child of similar age, intelligence, and experience
• Common carriers (airlines, buses, railroads) are typically held to a higher duty of care toward passengers

Intentional Torts

Intentional torts require proof that the defendant acted deliberately to cause harm or with knowledge that harm was substantially certain to result. Key intentional torts include:

• Battery: Intentional harmful or offensive physical contact
• Assault: An act that places another in reasonable apprehension of imminent battery (no contact necessary)
• Defamation: False statements of fact published to third parties that damage reputation; libel (written) and slander (spoken) are subcategories
• Intentional infliction of emotional distress (IIED): Extreme and outrageous conduct deliberately causing severe emotional harm
• Trespass to land or chattel: Unauthorized interference with property

Strict Liability

Strict liability imposes legal responsibility regardless of fault or intent. Courts apply strict liability in two main contexts: abnormally dangerous activities (such as blasting or storing toxic chemicals) and product liability for defective products.

In product liability, a manufacturer, distributor, or seller can be held strictly liable if a product is defective in design, manufacture, or warnings, and that defect causes harm to a consumer — even if the seller was not negligent and had no knowledge of the defect.

Types of Damages

Defenses to Tort Claims

Defendants in tort cases may raise several defenses:

• Contributory negligence: In a small number of U.S. states, any fault by the plaintiff bars recovery
• Comparative negligence: Most states use this standard — the plaintiff's damages are reduced in proportion to their share of fault
• Assumption of risk: The plaintiff voluntarily encountered a known risk
• Statute of limitations: Claims filed after the legally permitted time period are barred
• Consent: The plaintiff agreed to the conduct (relevant in intentional tort cases)
