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

Ouellette v. Blanchard replaced the entrant categories with a single test of reasonable care under all the circumstances, and the court explained that "the traditional tort test of foreseeability determines the liability or nonliability of the landowner". Neither Ouellette nor Rallis v. Demoulas Super Markets addresses hazards that are open and obvious.

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's unified duty of reasonable care under all the circumstances, established in Ouellette v. Blanchard, governs all owners and occupiers of land. Rallis v. Demoulas Super Markets restates that a premises owner owes entrants a duty of ordinary care to keep the premises reasonably safe, and it describes Simpson v. Wal-Mart Stores, 144 N.H. 571 (1999), as upholding the denial of a directed verdict where the jury could have found that the store knew or should have known that icy conditions on its exit way created a hazard to customers and failed to take preventative action.

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 also not adopted a judicial "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. As a matter of common law, the New Hampshire duty of reasonable care applies continuously, and the fact that a storm is ongoing does not automatically postpone it.

That is the common-law picture, and it is not the whole picture. The legislature has supplied a statutory safe harbor that covers the single most common New Hampshire winter fact pattern, a plowed and salted parking lot or walkway maintained under contract. Under RSA 508:22, I, no commercial applicator certified under RSA 489-C:2, and no owner, occupant, or lessee of land whose premises is maintained by such an applicator, is liable for damages arising from hazards "caused solely by snow or ice," "even with actual notice thereof," where the failure or delay in removing or mitigating the hazard results from implementing the best management practices for winter road, parking lot, and sidewalk maintenance adopted and published by the New Hampshire Department of Transportation and the Department of Environmental Services. Gross negligence or reckless disregard of the hazard defeats the protection. Ordinary negligence does not.

The statute also builds in a presumption and a paper trail. Anyone who adopts those best management practices is presumed to be acting under them "in the absence of proof to the contrary," so the practical burden falls on the injured person to show the defendant departed from them. RSA 508:22, II conditions the protection on keeping a written record of the de-icing materials used, the rate or quantity applied, the treatment dates, and the weather conditions for each event requiring de-icing, retained for three years. Those records are among the first things to request in a New Hampshire ice case, because whether the defendant actually followed the practices it claims to follow is usually where the case is won or lost. RSA 508:22 took effect in 2013 and was amended effective July 1, 2021.

Falls on public sidewalks, streets, and highways are governed by a separate and even more protective rule. RSA 231:92-a bars a municipality or school district from liability for hazards "caused solely by snow, ice, or other inclement weather," even where it has actual notice or knowledge of them, when its failure or delay in removing or mitigating the hazard results from implementing a winter or inclement weather maintenance policy or set of priorities adopted in good faith by the responsible officials, absent gross negligence or reckless disregard. Municipal and school-district employees and officials are presumed to be acting under such a policy absent proof to the contrary.

Case law supplies one further boundary. Rutkauskas v. Hodgins, 120 N.H. 788 (1980) held there is no strict liability for a building that redirected precipitation onto an adjacent public sidewalk. Rutkauskas is narrow: it rejects strict (no-fault) liability in that specific context, not the ordinary reasonable-care duty, and owners may still be liable for redirected precipitation where their own negligence contributed to the hazard. It should not be misread as a broad natural-accumulation shield. But it is no longer the operative limit either. The controlling limits on New Hampshire snow and ice liability today are statutory: RSA 508:22 for private premises and RSA 231:92-a for public ways.

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. To stay clear of that prejudice fight, ask a New Hampshire injury lawyer for a free consultation on sending the written notice to the responsible agency within the 180 days (attorney advertising).

Claims against municipalities and local governmental units work differently, and the difference is substantive rather than just a matter of dates. RSA chapter 507-B governs municipal liability generally, but RSA 507-B:2 carves out the most common slip and fall setting: "the liability of any governmental unit with respect to its sidewalks, streets, and highways shall be limited as provided in RSA 231."

Under RSA 231:92, I, a municipality is not liable for an injury arising from an insufficient class IV or class V highway, bridge, or sidewalk unless one of three things is true: it received written notice of the insufficiency under RSA 231:90 and then failed to act as RSA 231:91 requires; a selectman, highway agent, mayor, or street commissioner had actual knowledge of the insufficiency and was grossly negligent or exercised bad faith in responding to it; or the condition was created by an intentional act of a municipal officer or employee. RSA 231:92, II adds a pleading hurdle: the complaint must describe with particularity the means by which the municipality received actual notice of the alleged insufficiency, or the intentional act that created it. RSA 231:90, II narrows "insufficient" itself to a way that is not passable in any safe manner by those permitted on it, or a safety hazard that is not reasonably discoverable or reasonably avoidable by a person traveling prudently and in obedience to posted regulations, given prevailing visibility and weather conditions.

Two consequences follow. First, on the filing calendar there is no separate short pre-suit notice period for a municipal claim. The written notice under RSA 231:90 is a predicate for liability, not a deadline for bringing suit, so the general 3-year limitation period under RSA 508:4 still governs when you must file. That is not the same as nothing extra applying. Second, if the hazard was snow or ice, RSA 231:92-a is likely to be decisive on its own, because it bars municipal and school-district liability for weather-caused hazards even with actual notice where a good-faith winter maintenance policy was implemented without gross negligence.

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.

Frequently Asked Questions

How do I prove a slip and fall in New Hampshire?

You must establish four elements: (1) the owner owed you a duty of reasonable care (all landowners owe this unified duty under Ouellette v. Blanchard, 116 N.H. 552 (1976)); (2) a dangerous condition existed on the premises; (3) the owner had actual or constructive notice of the hazard and failed to fix or warn of it within a reasonable time; and (4) that failure caused your injury. Constructive notice means the hazard existed long enough that a reasonable owner conducting ordinary inspections should have discovered it.

Is New Hampshire an open-and-obvious state?

New Hampshire landowners are governed by a single test of reasonable care under all the circumstances under Ouellette v. Blanchard, 116 N.H. 552 (1976), in which foreseeability determines liability. The victim's awareness of the condition is weighed as comparative fault under RSA 507:7-d, which bars recovery only if the plaintiff's fault exceeds the defendant's (51% or more).

Can I sue for falling on ice or snow in New Hampshire?

Sometimes, but two statutes shield a large share of New Hampshire ice and snow defendants. At common law owners owe the ordinary reasonable-care duty, and Rallis v. Demoulas Super Markets describes an earlier case in which a jury could find a store liable for icy conditions on its exit way that it knew or should have known about; the courts have not adopted a 'storm-in-progress' doctrine. However, RSA 508:22 bars liability for hazards 'caused solely by snow or ice,' even with actual notice, where the premises is maintained by a commercial applicator certified under RSA 489-C:2 and the delay in clearing results from implementing the state's published winter best management practices, absent gross negligence or reckless disregard. For a fall on a public sidewalk, street, or highway, RSA 231:92-a gives municipalities and school districts a parallel bar where a good-faith winter maintenance policy was implemented. Whether the defendant actually followed those practices, and whether it kept the three years of de-icing records RSA 508:22, II requires, is often the decisive question.

How long do I have to file a slip and fall lawsuit in New Hampshire?

New Hampshire's general personal injury statute of limitations is 3 years from the date of the accident (or from discovery) under RSA 508:4. If your fall was on state property, you must also provide written notice to the responsible state agency within 180 days under RSA 541-B:14. Missing the 180-day window does not automatically bar the claim, but the State can argue prejudice, so timely notice is strongly advisable.

Can I recover if I was partly at fault for my fall in New Hampshire?

Yes, as long as your share of fault is not greater than the defendant's (i.e., 50% or below). New Hampshire's modified-51 comparative negligence rule under RSA 507:7-d reduces your damages by your percentage of fault. A plaintiff who is 50% at fault still recovers (damages reduced by half). Only if you are found 51% or more at fault is recovery completely barred.

How much is a New Hampshire slip and fall claim worth?

Value depends on your economic losses (medical bills, lost wages, future care costs) plus non-economic damages (pain and suffering, loss of enjoyment of life). New Hampshire does not cap non-economic damages against a private defendant. If your claim is against a state agency, RSA 541-B:14, I caps your total recovery at $475,000 per claimant and $3,750,000 per incident. Your net recovery is reduced by your comparative fault percentage under RSA 507:7-d. Use the New Hampshire Slip and Fall Settlement Calculator to estimate a range, then consult an attorney for a case-specific assessment.

What is the notice deadline for falls on government property in New Hampshire?

For falls on state property, RSA 541-B:14 requires written notice to the responsible state agency within 180 days of the injury as a condition precedent to suit, stating the date, time, and location. For falls on municipal property there is no comparable short pre-suit notice deadline, so the general 3-year limitation period under RSA 508:4 governs when you must file. The deadline is the easy part, though. RSA 507-B:2 limits a municipality's liability for its sidewalks, streets, and highways 'as provided in RSA 231,' and under RSA 231:92 the town is not liable at all unless it got written notice of the insufficiency under RSA 231:90 and failed to act, a named official had actual knowledge and was grossly negligent or acted in bad faith, or a municipal officer intentionally created the condition. The complaint must plead that notice with particularity.
