New Mexico Slip and Fall Laws: Proving Premises Liability Under Pure Comparative Negligence

To win a slip and fall claim in New Mexico, you must prove that the property owner failed to use ordinary reasonable care to keep the premises safe and that this failure caused your injury. New Mexico applies pure comparative negligence, so partial fault reduces but does not bar your recovery.

Proving a slip and fall claim in New Mexico

New Mexico slip and fall claims are governed by the ordinary premises-liability standard of reasonable care. Unlike some states that have enacted a statutory premises-liability act, New Mexico applies a unified common-law framework rooted in the duty of reasonable care owed to entrants on the property, with the standard of care shaped by decades of case law including Klopp v. Wackenhut Corp., 113 N.M. 153, 824 P.2d 293 (1992).

A property owner or occupier must use ordinary care to keep the premises reasonably safe and to warn of or remedy dangerous conditions that pose an unreasonable risk of harm. The duty generally runs to invitees and licensees; trespassers receive a narrower duty. As an invitee (a customer, tenant, or visitor invited onto the property), the owner must exercise reasonable care both to discover dangerous conditions and to repair or warn about them.

Notice is the key battleground in most slip and fall cases. You must prove the owner had actual notice (an employee created the hazard or was told about it) or constructive notice (the condition existed long enough that a reasonable inspection would have found it). Courts look to evidence like store inspection logs, surveillance video, how long the hazard had been present, and whether prior complaints were made. The New Mexico Uniform Jury Instructions (NM UJI 13-1309 et seq.) guide juries through these questions. The leading case on the duty framework is Klopp v. Wackenhut Corp., which held that simply by making a hazard obvious, an occupier cannot avoid liability to a business visitor for dangers that could otherwise be made safe through reasonable means.

The open-and-obvious doctrine in New Mexico

New Mexico generally does not allow the open-and-obvious nature of a hazard to serve as a complete bar to recovery. In Klopp v. Wackenhut Corp., 113 N.M. 153, 824 P.2d 293 (1992), the New Mexico Supreme Court disapproved the open-and-obvious danger jury instruction (UJI 13-1310) as inappropriate under comparative fault and held that whether an obvious condition posed an unreasonable risk to a business visitor is for the jury to decide in virtually every case. The court kept a narrow no-duty exception where the visitor's encounter with the known danger was so extraordinary as to be unforeseeable.

The court held that an occupier cannot avoid liability to a business visitor simply by making a hazard obvious when the danger could otherwise be made safe through reasonable means. A risk is not made reasonable just because it is open and obvious. The key questions, whether a condition posed an unreasonable risk and whether the owner should have anticipated harm despite the obvious nature of the hazard, are jury questions.

In practice, the comparative treatment works like this: if you were aware of an obvious hazard and chose to proceed anyway, the jury may assign you a share of the fault for the accident. That share reduces your recovery proportionally. The owner can also argue to the jury that the obvious nature of the condition meant it did not involve an unreasonable risk of danger, which goes to whether the owner was negligent at all. But in most cases the obviousness of a hazard does not end your claim before a jury weighs it, the way it would in states that treat open-and-obvious as a complete bar.

Ice, snow, and natural accumulation in New Mexico

New Mexico does not follow the "natural accumulation" rule that grants landowners immunity for ice or snow that fell naturally. In states with such a rule, an owner can argue the hazard was simply weather and bears no responsibility. New Mexico rejected that approach.

Because New Mexico applies its ordinary premises-liability standard of reasonable care to all entrants (other than trespassers), that duty extends to weather-related hazards including icy walkways, snow-covered steps, and slick entryways. There is no New Mexico statute or appellate decision that carves out an immunity for naturally accumulated ice or snow. Klopp v. Wackenhut Corp. (1992), which held that an obvious hazard usually does not by itself eliminate an occupier's duty of ordinary care to a business visitor, is consistent with applying the ordinary reasonable-care duty to weather-related hazards, though Klopp involved a tripping hazard at an airport security station and does not address ice or snow.

What this means in practice: if a commercial parking lot has a known ice patch that has persisted for several days, if a landlord's exterior stairs regularly freeze after storms and tenants have reported the issue, or if a building entryway collects water that freezes overnight, the owner cannot simply assert "the ice fell naturally" as a defense. Liability turns on what the owner knew or should have known and whether the response was reasonably prompt. The plaintiff's own awareness and care are handled through New Mexico's pure comparative-negligence apportionment rather than a categorical no-duty rule.

How fault is shared: New Mexico's negligence rule

New Mexico applies pure comparative negligence, adopted judicially in Scott v. Rizzo, 96 N.M. 682, 634 P.2d 1234 (1981), which abolished the old all-or-nothing contributory-negligence rule. Under pure comparative negligence, a plaintiff's damages are reduced by their own percentage of fault, with no bar threshold whatsoever.

A plaintiff who is 50% at fault recovers 50% of their damages. A plaintiff who is 90% at fault still recovers 10% of their damages. There is no cutoff point at which the plaintiff is barred from recovery entirely, unlike the modified comparative-negligence rules (50% or 51% bars) used by many neighboring states.

New Mexico also applies several liability (NMSA 1978, § 41-3A-1) rather than joint-and-several liability in most cases. This means that each defendant generally pays only its own proportionate share of the total fault, not the shares of co-defendants who cannot pay. In a slip and fall involving a building owner and a property-management company, for instance, each would pay only the percentage of fault the jury assigns to them.

The practical takeaway: do not assume that being partly responsible for your fall ends your case in New Mexico. An insurer's argument that "you should have watched where you were going" does not bar your recovery; it only affects the final damages percentage.

Deadlines: statute of limitations and government claims

New Mexico imposes two distinct deadlines that slip and fall victims must track, and missing either one can permanently end a valid claim.

Personal-injury statute of limitations: Under NMSA 1978, § 37-1-8, you have 3 years from the date of injury to file a personal-injury lawsuit in New Mexico court. The clock generally starts on the date of the fall. Minors receive tolling under NMSA 1978, § 37-1-10: any minor has until 1 year after reaching the age of majority (18) or 3 years from the date of injury, whichever is longer. (A separate, narrower rule applies only to claims against government defendants under the Tort Claims Act, NMSA 1978, § 41-4-15(A) -- a minor under the full age of 7 has until their ninth birthday to file -- discussed in the government-notice section below.) For more on New Mexico's civil filing deadlines, see the New Mexico statute of limitations page.

Government notice of claim (90 days): If your fall occurred on government property, a much shorter and more unforgiving deadline applies. The provision that makes such a claim possible at all is NMSA 1978, § 41-4-6, which waives governmental immunity for bodily injury, wrongful death, or property damage caused by the negligence of public employees acting within the scope of their duties in the operation or maintenance of any building, public park, machinery, equipment, or furnishings. Under the New Mexico Tort Claims Act, NMSA 1978, § 41-4-16(A), you must present a written notice of claim within 90 days of the occurrence to the appropriate official. For state entities the notice goes to the Risk Management Division; for municipalities, to the mayor; for counties, to the county clerk; for school districts, to the superintendent; for other local bodies, to the administrative head. The 90 days count from the day of the fall, so get a free consultation with a New Mexico premises liability lawyer on getting that written notice to the right official in time (attorney advertising).

The stakes are severe: NMSA 1978, § 41-4-16(B) provides that no suit may be maintained and no court has jurisdiction unless written notice was given OR the governmental entity had actual notice. Missing the 90-day deadline can result in dismissal for lack of jurisdiction, not merely a procedural misstep. Two limited extensions exist: wrongful-death claims have a 6-month notice window rather than 90 days, and the 90-day period is tolled (up to 90 additional days) while the injured person is incapacitated by the injury. The Tort Claims Act itself also sets a separate 2-year period under NMSA 1978, § 41-4-15(A) to actually file suit against a government defendant, shorter than the general 3-year personal-injury period.

What a New Mexico slip and fall claim is worth

The value of a slip and fall settlement or verdict in New Mexico depends on the severity of your injuries, the strength of your liability evidence, and any fault assigned to you.

Economic damages cover your actual, measurable financial losses: emergency room and hospital bills, surgery and rehabilitation costs, projected future medical expenses, lost wages while you recovered, and any reduction in future earning capacity. Economic damages are not capped in New Mexico premises-liability cases against private property owners.

Non-economic damages compensate for pain and suffering, emotional distress, disfigurement, loss of enjoyment of life, and similar intangible harms. New Mexico does not impose a statutory cap on non-economic damages in slip and fall cases against private property owners, which means that for serious injuries, juries can award amounts that reflect the true impact of the harm.

Claims against government defendants are capped. If you fell on state, city, county, or school-district property, the uncapped rule above does not apply to your claim. NMSA 1978, § 41-4-19 limits Tort Claims Act recovery to $300,000 for all past and future medical and medically related expenses arising out of a single occurrence, $400,000 to any person for any number of claims arising out of a single occurrence for all damages other than real-property damage and medical expenses, and $750,000 in total for all property-damage and non-medical claims arising out of that single occurrence. The same section also bars punitive damages and prejudgment interest against a government defendant. These limits apply no matter how severe the injury, so an identical fall can be worth far less on public property than in a private store.

Comparative-fault reduction: Whatever total damages a jury finds, they are reduced by your percentage of fault. At 20% fault, you receive 80% of the verdict. At 60% fault, you still receive 40%. New Mexico's no-cutoff pure comparative rule means that even a plaintiff bearing the majority of the fault can recover something, though the reduction can be significant.

Frequently Asked Questions

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

You must show that the property owner owed you a duty of reasonable care, that a dangerous condition existed on the premises, that the owner had actual or constructive notice of the hazard, that the owner failed to remedy or warn about it, and that the failure caused your injuries. Constructive notice is established by showing the condition existed long enough that a reasonable inspection would have found it. Evidence includes surveillance video, inspection logs, prior complaints, and witness testimony.

Is New Mexico an open-and-obvious state?

Not usually. In Klopp v. Wackenhut Corp., 113 N.M. 153 (1992), the New Mexico Supreme Court disapproved the open-and-obvious jury instruction, so the visibility of a hazard typically does not eliminate an occupier's duty of ordinary care to a business visitor. The jury weighs it in deciding whether the risk was unreasonable, whether the owner was negligent, and how to apportion fault, though a court can still find no duty where the visitor's encounter with the known danger was so extraordinary as to be unforeseeable.

Can I sue for falling on ice in New Mexico?

Yes. New Mexico does not follow the natural-accumulation rule, so property owners are not automatically immune when someone falls on naturally occurring ice or snow. Landowners owe ordinary reasonable care to address all dangerous conditions on their property, including weather-related ones. Whether the owner acted reasonably given what they knew or should have known is a jury question, not a threshold bar.

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

Three years from the date of injury under NMSA 1978, § 37-1-8. If your fall occurred on government property (a public sidewalk, city park, state building, or school), you must also file a written notice of claim with the relevant government entity within 90 days of the incident under the New Mexico Tort Claims Act (NMSA 1978, § 41-4-16), and the Tort Claims Act gives you only 2 years to file the suit itself (NMSA 1978, § 41-4-15(A)). Missing the 90-day notice deadline can result in dismissal for lack of jurisdiction, even if the 3-year general deadline has not expired.

Can I recover damages if I was partly at fault for my fall?

Yes, under any level of fault. New Mexico uses pure comparative negligence (Scott v. Rizzo, 96 N.M. 682 (1981)), which means there is no percentage cutoff. Your damages are simply reduced by your share of the fault. Even if a jury finds you 80% at fault, you can still recover 20% of your total damages. This is more plaintiff-friendly than states that bar recovery at 50% or 51% fault.

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

Value depends on your economic losses (medical bills, lost wages, future care costs), your non-economic losses (pain and suffering, loss of enjoyment of life), and your share of fault. New Mexico caps neither economic nor non-economic damages in claims against private property owners. Claims against government entities are capped: NMSA 1978, § 41-4-19 limits Tort Claims Act recovery to $300,000 for all past and future medical and medically related expenses arising out of a single occurrence, $400,000 to any person for all other damages from that occurrence, and $750,000 in total for all property-damage and non-medical claims arising out of that occurrence, and it bars punitive damages entirely. Your total recovery is then reduced by your percentage of comparative fault.

What is the government notice-of-claim deadline for a fall on public property in New Mexico?

Under NMSA 1978, § 41-4-16, you must submit written notice of your claim within 90 days of the incident to the appropriate government official (state Risk Management Division, city mayor, county clerk, school superintendent, or other administrative head). Wrongful-death claims have a 6-month window. Missing this deadline can result in dismissal for lack of jurisdiction, and the Tort Claims Act imposes a separate 2-year period under NMSA 1978, § 41-4-15(A) to file the actual lawsuit against a government defendant.
