Negligent infliction of emotional distress: when careless conduct causes emotional harm

Negligent infliction of emotional distress, often shortened to NIED, is the set of rules courts use to decide when careless conduct makes a defendant pay for emotional injury alone. Cornell's Wex encyclopedia defines it as emotional distress caused by negligent action and notes that states differ greatly on when they allow it (Wex: NIED).

How NIED differs from intentional infliction

The difference is the defendant's state of mind. Intentional infliction of emotional distress requires intentional or reckless conduct that is outrageous, plus severe distress. NIED rests on ordinary negligence, so courts limit NIED mainly by restricting who can bring a claim. Our guide to intentional infliction of emotional distress covers the other claim.

Three ways states limit the claim

Wex sorts the states into three broad groups:

• Foreseeability. Most states allow a claim when the defendant's conduct was reasonably foreseeable to cause the emotional distress.
• Zone of danger. Some states allow a claim only when the plaintiff nearly suffered physical harm and feared it. Wex gives the example of a diner seated near a server who is assaulted and who may have believed the attacker would turn on them next.
• Physical injury. A few states require at least some physical injury to the plaintiff before any NIED claim can proceed.

These groupings are a starting point. A state's courts may combine approaches or carve out categories, so the case law in the state where the injury happened controls.

Direct victims and bystanders

Many courts separate two kinds of plaintiff. A direct victim claims distress from a breach of a duty the defendant owed to that person. A bystander claims distress from watching someone else, usually a family member, get hurt. California's jury instructions use the same split: CACI No. 1620 for direct victims and CACI No. 1621 for bystanders (CACI Nos. 1620 and 1621).

California's bystander rules

California opened the door to bystander claims in Dillon v. Legg (1968), a case about a mother who saw her daughter killed, quoted in the Sources and Authority for CACI No. 1621. The California Supreme Court later tightened the rule in Thing v. La Chusa (1989). Without physical injury to the plaintiff, recovery requires that the plaintiff:

1. is closely related to the injured person;
2. was at the scene when the injury-causing event happened and understood at that moment that it was injuring the victim; and
3. suffers emotional distress beyond what a disinterested witness would feel.

CACI No. 1621 turns those requirements into jury elements: the defendant negligently caused injury or death to the victim, the plaintiff was at the scene and understood in the moment that the event was hurting the victim, the plaintiff suffered serious emotional distress, and the defendant's conduct was a substantial factor. The Directions for Use say the judge, not the jury, decides whether the relationship was close enough, because that question goes to whether any duty was owed.

Recent decisions have shaped the presence and awareness requirements. The instruction now allows a plaintiff to have been virtually present through technology, following a 2020 appellate decision involving parents who saw and heard their child being abused as it happened, through technology that extended their senses beyond their home. In Downey v. City of Riverside (2024), the California Supreme Court allowed a mother who heard a crash over the phone, and knew her daughter had been hurt, to proceed. The court held the bystander must be aware of the injury-causing event but need not know at the time what role the defendant played.

California's direct victim cases

CACI No. 1620 requires proof that the defendant was negligent, that the plaintiff suffered serious emotional distress, and that the negligence was a substantial factor in causing it. The hard part is duty. The Directions for Use note that the California Supreme Court has allowed direct-victim recovery in only three types of situations: negligent mishandling of a body, negligent misdiagnosis of a disease that could harm another person, and negligent breach of a duty arising from a preexisting relationship.

Both instructions treat distress as serious when an ordinary, reasonable person could not be expected to cope with it. They describe emotional distress broadly, covering feelings that range from fright and grief to anxiety, humiliation and shame. One California appellate court, in Wong v. Jing (2010), held that serious distress for NIED is the same as severe distress for intentional infliction, while a later appellate decision, Keys v. Alta Bates Summit Medical Center (2015), found the instruction's cope-with-it description correct.

Questions to sort a possible NIED claim

• Were you hurt physically, or only emotionally? Some states require a physical injury.
• Were you in danger yourself? Zone of danger states turn on this.
• Did you witness harm to someone else? Note your relationship and how you perceived the event.
• How serious is the distress? Keep records of treatment, counseling and effects on daily life.
• Which state's law applies? The approaches differ widely, and so do filing deadlines.
