Assumption of Risk

Assumption of risk is a legal defense that can bar or reduce a plaintiff's recovery in a personal injury case when the plaintiff voluntarily encountered a known risk that caused their injury. The doctrine is based on the principle that a person who knowingly accepts the dangers inherent in an activity should not be able to hold others liable for injuries that arise from those very dangers. It is commonly raised in cases involving sports, recreational activities, and voluntary participation in known dangerous endeavors.

There are two primary forms of assumption of risk: express and implied. Express assumption of risk occurs when a person explicitly agrees — typically through a written waiver or liability release — to accept the risks associated with an activity. Such waivers are commonly used by gyms, ski resorts, adventure sports companies, and other businesses. Courts vary in how strictly they enforce these waivers, particularly when they are broadly worded or when they attempt to excuse a party from liability for gross negligence.

Implied assumption of risk occurs when a person's conduct demonstrates that they knowingly and voluntarily chose to encounter a recognized risk, even without a formal agreement. For example, a spectator who sits in an area where foul balls frequently land during a baseball game may be deemed to have assumed the risk of being hit by a foul ball. Similarly, a participant in a contact sport assumes the risk of injuries that are inherent and foreseeable in that sport.

The merger of assumption of risk into comparative negligence frameworks has become common in many states, transforming what was once a complete bar to recovery into a factor that reduces the plaintiff's damages proportionately. Courts continue to distinguish between primary assumption of risk — where no duty exists and the claim is barred entirely — and secondary assumption of risk — where the defendant was negligent but the plaintiff voluntarily encountered the resulting risk, which is then analyzed under comparative fault rules.
