Liability

Liability in personal injury law refers to the legal responsibility a party bears for causing harm to another person or their property. When a defendant is found liable, they are obligated to compensate the injured plaintiff for the damages that resulted from their wrongful conduct. Liability can arise from various legal theories including negligence, strict liability, intentional torts, and breach of contract, depending on the nature of the conduct and the relationship between the parties.

Establishing liability requires the plaintiff to prove that the defendant owed them a legal duty, that the defendant breached that duty, that the breach directly caused the plaintiff's injuries, and that the plaintiff suffered quantifiable damages as a result. These four elements — duty, breach, causation, and damages — form the foundation of most personal injury claims. The burden of proof in civil cases is preponderance of the evidence, meaning the plaintiff must show it is more likely than not that the defendant is liable.

Liability can be shared among multiple parties in cases involving more than one negligent actor. Under joint and several liability, each defendant can be held responsible for the full amount of damages regardless of their individual share of fault. Under proportionate liability rules adopted in many states, each defendant is only responsible for their proportionate share of damages. Insurance companies play a major role in managing liability exposure — most defendants' legal obligations are ultimately satisfied through insurance policies.

There are also theories of vicarious liability, under which a party can be held responsible for the negligent acts of another. Employers are commonly held vicariously liable for the tortious conduct of their employees committed within the scope of employment. Parents may be vicariously liable for certain acts of their minor children. Understanding who bears liability — and under what legal theory — is a fundamental step in building any personal injury case.
