New Hampshire Slip and Fall Laws: Proving Premises Liability

To win a slip and fall claim in New Hampshire, you must prove the property owner was negligent by showing the owner knew or should have known about the hazard, failed to fix or warn of it, and that failure caused your injury. New Hampshire applies modified-51 comparative negligence, which reduces or bars recovery depending on your share of fault.

Proving a slip and fall claim in New Hampshire

New Hampshire premises liability law was fundamentally reshaped by Ouellette v. Blanchard, 116 N.H. 552 (1976), in which the New Hampshire Supreme Court abolished the traditional invitee/licensee/trespasser status categories. In their place, the court imposed a single duty of reasonable care under all the circumstances on every landowner. That unified framework means the analysis for a business visitor and a social guest is governed by the same reasonableness standard, not by separate, tiered duties.

Rallis v. Demoulas Super Markets, Inc., 159 N.H. 95 (2009) restates the operative standard: a premises owner must use ordinary care to keep the premises in a reasonably safe condition and to warn of, or remedy, dangerous conditions it knows or should know exist. The notice element is central to most cases. A defendant who had no actual or constructive knowledge of the hazard typically cannot be held liable.

Constructive notice arises when a condition exists long enough that a reasonably prudent owner exercising ordinary care would have discovered and corrected it. Courts weigh how visible the hazard was, how long it had been present, and whether the owner maintained a reasonable inspection schedule. If the condition was caused by the owner's own employees or by a pattern of prior incidents, a court may infer constructive notice more quickly.

Causation must also be established. The hazard must have actually caused your fall and resulting injuries. A property owner is not an insurer of the safety of everyone who enters; you must link the specific defect to your specific harm.

The open-and-obvious doctrine in New Hampshire

New Hampshire does NOT apply the open-and-obvious doctrine as a no-duty bar. Under Ouellette v. Blanchard and Rallis v. Demoulas Super Markets, the owner's duty of reasonable care is not extinguished merely because a hazard is visible or should have been noticed by the entrant. The owner must still anticipate that a person may be harmed despite the danger being apparent; distraction, the need to use a particular path, or other circumstances can make harm foreseeable even from an obvious condition.

A plaintiff's own awareness of the hazard is not irrelevant. Under the comparative-fault framework of RSA 507:7-d, the jury will weigh that awareness as a factor bearing on how much fault to assign the plaintiff. If the jury concludes the plaintiff's fault is greater than the defendant's (more than 50%), recovery is barred. But the case proceeds to that fault-allocation analysis; a visible hazard does not win summary judgment for the defendant as a matter of law.

In practical terms, encountering an obvious hazard that a reasonable person would avoid will hurt your case at trial, because the jury may assign you a larger share of fault. It does not, however, end the case automatically. New Hampshire treats open-and-obvious as a comparative-fault factor, not a complete defense.

Ice, snow, and natural accumulation in New Hampshire

New Hampshire does NOT follow the rigid "natural accumulation" no-duty rule that shields property owners in states like Illinois and Ohio. Under the unified reasonable-care duty established in Ouellette v. Blanchard and restated in Rallis v. Demoulas Super Markets, owners owe an ongoing duty of ordinary care to keep their premises reasonably safe, and that duty extends to naturally accumulated snow and ice.

What "ordinary care" requires is judged case-by-case. Courts consider factors such as anticipated foot traffic, the magnitude of the slipping risk, and the burden of removal or treatment. Depending on the circumstances, ordinary care may require salting, sanding, plowing, rerouting foot traffic, or posting warnings about conditions like black ice that may not be easily visible.

New Hampshire has NOT adopted the "storm-in-progress" doctrine. That doctrine, followed in several other states, gives property owners a window of suspension during an active storm before the duty to clear ice and snow kicks in. In New Hampshire, the duty of reasonable care applies continuously; the fact that a storm is ongoing does not automatically postpone it.

One important boundary on liability comes from Rutkauskas v. Hodgins, 120 N.H. 788 (1980). That case held there is no strict liability for a building that redirected precipitation from its roof onto an adjacent public sidewalk. Rutkauskas is narrow: it rejects strict (no-fault) liability in that specific context, not the ordinary reasonable-care duty. Owners in New Hampshire may still be liable for redirected precipitation if their negligence contributed to the hazard. The case should not be misread as a broader natural-accumulation shield.

How fault is shared: New Hampshire's negligence rule

New Hampshire follows modified comparative negligence under RSA 507:7-d. Under this rule, a plaintiff's damages are reduced in direct proportion to their own percentage of fault. A plaintiff who is 25% at fault in a $100,000 case receives $75,000.

The critical threshold is 51%. RSA 507:7-d bars recovery only if the plaintiff's contributory fault "was greater than the fault of the defendant" (or the aggregate fault of all defendants if there are multiple). A plaintiff who is exactly 50% at fault still recovers (fault is equal to, not greater than, the defendant's 50%). A plaintiff found 51% at fault is completely barred.

This makes New Hampshire a modified-51 state, one rung more plaintiff-friendly than modified-50 states (like Maine) where a 50/50 finding bars recovery. New Hampshire is decidedly not one of the four pure-contributory states (Alabama, Maryland, North Carolina, Virginia) or the District of Columbia, where even 1% of fault by the plaintiff can bar all recovery.

Where multiple defendants are responsible, each defendant's percentage of fault is assessed individually. RSA 507:7-d directs the reduction against the defendant or defendants whose combined fault is measured against the plaintiff's fault.

Deadlines: statute of limitations and government claims

New Hampshire's general personal injury statute of limitations is 3 years, established by RSA 508:4, I. The clock typically starts on the date of the fall itself. However, RSA 508:4 also contains a discovery-rule provision: where the injury and its causal relationship to the defendant's conduct were not reasonably discoverable at the time of the accident, the 3-year period runs from when the plaintiff discovered, or reasonably should have discovered, both the injury and its cause.

Disability tolling is available under RSA 508:8 for minors and persons under legal disability. For a child injured in a slip and fall, the statute of limitations may be tolled until the child reaches majority, though best practice is to investigate promptly regardless of tolling.

If your fall occurred on state-owned property, RSA 541-B:14, IV requires written notice to the responsible state agency within 180 days after the injury. The notice must state the date, time, and location of the incident. Missing the 180-day window does not automatically bar the claim in New Hampshire; the claim is barred only if the State proves by a preponderance of the evidence that its ability to defend was substantially prejudiced by the late notice. Even so, acting within the 180-day window eliminates that risk entirely.

Claims against municipalities and local governmental units are different. RSA chapter 507-B governs municipal liability, setting damage caps and limiting the scope of government immunity. Importantly, there is no separate short pre-suit notice period for municipal claims; those cases are governed by the general 3-year personal injury statute of limitations under RSA 508:4.

What a New Hampshire slip and fall claim is worth

New Hampshire slip and fall settlements and verdicts typically include two categories of damages. Economic damages cover your measurable financial losses: emergency-room and hospital bills, surgery, physical therapy and rehabilitation, future medical care, lost wages during recovery, and reduced earning capacity if the injury is permanent. These are calculated from medical records, billing statements, and employment documents.

Non-economic damages cover pain and suffering, emotional distress, loss of enjoyment of life, permanent scarring or disfigurement, and similar intangible harms. New Hampshire does not impose a statutory cap on non-economic damages in a claim against a private defendant. Jury awards for non-economic damages against a private defendant are bounded by what is reasonable and proportionate to the evidence, but there is no dollar ceiling. If your claim is against a state agency, however, RSA 541-B:14, I caps your total recovery (economic and non-economic combined) at $475,000 per claimant and $3,750,000 per single incident, or the amount of any applicable state insurance coverage if greater; punitive damages are barred entirely against the state.

Your net recovery is reduced by your share of comparative fault under RSA 507:7-d. If you are found 20% at fault, you keep 80% of total damages. If you are found 51% or more at fault, you recover nothing. Prompt documentation (photographs of the hazard, preserved incident reports, witness contact information) is critical because the evidence gathered in the hours and days after a fall shapes how the jury allocates fault.
