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 confirmed that an owner cannot escape liability by pointing to the obvious nature of the hazard.

The open-and-obvious doctrine in New Mexico

New Mexico 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 abolished the former open-and-obvious danger rule (previously embodied in UJI 13-1310) because it was incompatible with the state's pure comparative-negligence system.

The court held that a landowner or occupier cannot escape liability merely because they made a hazard visible or obvious. If the owner could have remedied the risk by reasonable means, the existence of an obvious danger does not eliminate the duty of reasonable care. 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. But it does not wipe out your claim at a threshold the way it would in states that treat open-and-obvious as a complete bar. This is a plaintiff-friendly rule that keeps even challenging cases alive and in front of a jury.

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. The rejection of rigid no-duty bars in Klopp v. Wackenhut Corp. (1992) and the unitary reasonable-care framework reflected in NM UJI 13-1309 et seq. make clear that owners are expected to address all dangerous conditions on their property within the scope of reasonable care.

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 -- a child under 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. 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 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 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.

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 standard slip and fall cases, which means that for serious injuries, juries can award amounts that reflect the true impact of the harm.

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.
