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, III 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 general personal injury cases. Jury awards for non-economic damages are bounded by what is reasonable and proportionate to the evidence, but there is no dollar ceiling.
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?
No. New Hampshire does not use the open-and-obvious doctrine as an automatic bar. Under Rallis v. Demoulas Super Markets, Inc., 159 N.H. 95 (2009), an owner must still anticipate that an entrant may be harmed by an apparent hazard. 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?
Yes. New Hampshire imposes an ordinary reasonable-care duty for naturally accumulated snow and ice and does not follow the 'storm-in-progress' doctrine. Under the framework of Ouellette v. Blanchard and Rallis v. Demoulas Super Markets, owners must take reasonable steps (salting, sanding, warning of black ice) to keep premises safe. You still must prove the owner had notice and a reasonable time to address the condition.
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 in general personal injury cases. 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. The notice must state the date, time, and location. For falls on municipal property, RSA chapter 507-B applies instead; there is no separate short pre-suit notice period, and those claims are governed by the general 3-year statute of limitations under RSA 508:4.
