Montana Slip and Fall Laws: Proving Premises Liability

To win a slip-and-fall claim in Montana, you must show that the property owner was negligent, that the owner knew or should have known about the hazard, and that the hazard caused your injury. Montana follows modified comparative negligence under MCA section 27-1-702, meaning your fault is weighed against the owner's.

Proving a slip and fall claim in Montana

Every person who enters a Montana property is owed the same standard of care: the property owner must use reasonable care to keep the premises reasonably safe and to warn of hidden dangers. Montana abolished the old invitee/licensee/trespasser hierarchy in Richardson v. Corvallis Public School District No. 1, 286 Mont. 309, 950 P.2d 748 (1997), and now applies a single, uniform duty to all entrants.

To succeed, you must prove four things: the owner had a duty of reasonable care (always present in Montana), the owner breached that duty by failing to correct or warn of a hazard, the breach caused your fall and injury, and you suffered actual damages. The most contested element is usually notice. You must show the owner either knew about the hazard (actual notice) or the hazard existed long enough that a reasonable inspection would have revealed it (constructive notice). If you cannot connect the owner to prior knowledge of the condition, the claim is likely to fail.

Evidence that supports notice includes prior complaints, inspection logs, surveillance footage showing how long the condition existed, and testimony from employees or other customers who observed the hazard before your fall. Documenting the scene immediately after the incident is critical.

The open-and-obvious doctrine in Montana

Montana does not use open-and-obvious as a complete bar to recovery. In Richardson v. Corvallis Public School District No. 1, the Montana Supreme Court expressly held that a possessor of land "may no longer avoid liability simply because a dangerous activity or condition on the land is open and obvious." The doctrine that once allowed defendants to win outright by arguing a hazard was plainly visible was abolished.

Under the current framework, the obviousness of a hazard is a factor the jury considers in the comparative-fault analysis. If a condition was clearly visible, the jury may assign a portion of fault to you for failing to observe it, but the owner is not relieved of liability simply because the hazard was easy to see. The critical question is whether the landowner should have anticipated that harm might occur despite the obvious nature of the condition.

This is a more plaintiff-friendly rule than in many states. If a court gives a traditional open-and-obvious no-duty instruction, it is reversible error under Montana law. The claim survives to trial.

Ice, snow, and natural accumulation in Montana

Montana also rejects the natural-accumulation rule, which is the doctrine used in some states (such as Illinois and Ohio) to relieve property owners of liability for falls on naturally accumulated ice and snow. Richardson v. Corvallis Pub. Sch. Dist. No. 1 expressly overruled prior Montana case law that distinguished between natural and altered accumulations.

Under current law, a Montana property owner owes the same ordinary duty of reasonable care for naturally accumulated ice and snow as for any other hazardous condition. The trier of fact determines whether the owner acted reasonably given the circumstances, such as how long the icy condition had existed, whether the owner had the ability to treat or sand the area, and what precautions were taken. A court that instructs the jury that an owner owes no duty for natural accumulation is committing reversible error.

This means a fall on an untreated sidewalk, parking lot, or step after a snowstorm can support a valid premises liability claim in Montana. The question is always whether the owner exercised reasonable care under the conditions.

How fault is shared: Montana's negligence rule

Montana uses modified comparative negligence with a 51% bar, codified at MCA section 27-1-702. Under this rule, your recovery depends on how the jury apportions fault between you and the property owner (or combined defendants).

If you are found 50% or less at fault, you recover damages reduced by your percentage of fault. For example, if your total damages are $100,000 and the jury finds you 30% at fault, you receive $70,000. If you are found exactly 50% at fault, you still recover half your damages.

However, if you are found 51% or more at fault, you recover nothing at all. This is the critical threshold. Defendants often raise comparative-fault arguments to push your share of blame above 50%, which would eliminate the claim entirely. Common arguments include that you were wearing inappropriate footwear, were distracted, or ignored visible warning signs.

Montana does not follow pure contributory negligence (which would bar recovery for any fault at all), so partial fault by the plaintiff does not automatically end the case.

Deadlines: statute of limitations and government claims

The standard deadline for filing a personal-injury lawsuit in Montana is three years from the date of the fall, under MCA section 27-2-204(1). Missing this deadline almost always results in the court dismissing your case, no matter how strong your evidence is. Do not wait to consult an attorney.

If you were injured on property owned or controlled by a Montana state or local government entity, there is an additional procedural step before you can file suit. Montana's Tort Claims Act (MCA section 2-9-301) requires that you first present a written claim to the appropriate agency. For state government claims, that is the Department of Administration. For local government claims, it is the clerk or secretary of the political subdivision.

For claims against the state, MCA section 2-9-301(2) gives the Department of Administration 120 days to grant or deny the claim in writing. If the department does not act within 120 days, that counts as a final denial, and you may then file suit; presentment to the department also tolls the statute of limitations for 120 days. For claims against a political subdivision (a city or county), MCA section 2-9-301(3) requires only that the claim be presented to the clerk or secretary of the political subdivision. That subsection does not set a 120-day response deadline or a tolling period, so do not assume the state-claim timeline applies to a local claim. Importantly, Montana does not impose a separate short notice-of-claim window (no 90- or 180-day trap as in many other states). You must present the claim, whether to the state or a political subdivision, within the three-year personal-injury limitations period.

What a Montana slip and fall claim is worth

The value of a Montana slip-and-fall claim depends on your actual losses and on how much fault the jury assigns to each party. Economic damages include medical expenses (past and future), lost wages, reduced earning capacity, and the cost of ongoing treatment or rehabilitation. These are calculated from bills, pay stubs, and expert testimony on future costs.

Non-economic damages cover pain and suffering, loss of enjoyment of life, and emotional distress. Montana does not impose a statutory cap on non-economic damages in personal-injury cases, so the jury has wide discretion in awarding these amounts.

Because Montana uses modified comparative negligence, your ultimate recovery is reduced by your percentage of fault. A $200,000 award to someone found 25% at fault nets $150,000. If the jury puts your fault at 51% or more, the award is zero. This is why documenting the hazard, owner notice, and your own conduct at the time of the fall is so important.
