Three Years to File, 90 Days to Act: What to Know Before Filing a New Mexico Injury Claim

On paper, New Mexico is one of the friendlier states in the country for injured people: a three-year window to file most lawsuits and a fault rule that lets you recover even if the accident was mostly your fault. The catch is that the friendly deadlines evaporate the moment a government entity is involved — and in New Mexico, with its state highways, county roads, public hospitals, and school districts, that happens more often than people expect.

The most forgiving fault rule in the country

New Mexico follows pure comparative negligence, a rule its courts adopted decades ago and one that only about a dozen states use. In plain terms: sharing fault does not bar your claim. Your recovery is simply reduced by your percentage of the blame. Found 30% at fault? You can generally recover the remaining 70% of your damages. Found 80% at fault? You can still generally recover the remaining 20%.

That is very different from the “modified” states surrounding the rule’s edges — Texas and Colorado, for example, cut recovery off entirely once your share of fault crosses a threshold. New Mexico has no cliff. The percentage still matters enormously, because every point of blame assigned to you shrinks what you recover, but there is no number at which the claim simply dies.

One wrinkle worth knowing: under NMSA § 41-3A-1, liability in most comparative-fault cases is several, meaning each defendant is generally responsible only for its own share of the damages rather than the whole award. In a multi-vehicle crash with several insurers pointing fingers at each other, that makes sorting out each party’s percentage the central fight of the case — and it is not a fight to take on casually.

Three years to file — usually

New Mexico’s general deadline for personal injury lawsuits is three years from the date of injury, under NMSA § 37-1-8. That is a full year longer than the two-year rule most states apply, and it is one reason injured New Mexicans sometimes feel less urgency than they should. (Curious how your neighbors compare? See our state-by-state statute of limitations guide.)

But the three-year figure is the general rule, not the whole story. Claims against government entities run on a shorter two-year clock. Medical malpractice claims travel under their own statutory scheme. And how the clock applies to late-discovered injuries can get complicated fast. Treat three years as the outer boundary, not a comfortable cushion, and confirm the deadline that applies to your specific situation with a licensed New Mexico attorney early.

The 90-day tripwire: claims involving the government

Here is the part of New Mexico law that quietly ends otherwise valid claims. If your injury involves a governmental entity — a city bus, a state agency vehicle, a public school, a dangerous condition on a county-maintained road — the Tort Claims Act generally requires written notice within 90 days of the occurrence under NMSA § 41-4-16. Miss it, and with limited exceptions a court cannot even hear the case.

The details are unforgiving in ways that surprise people:

• Notice goes to a specific official. For claims against the state, notice generally goes to the risk management division; for a municipality, the mayor; for a school district, the superintendent; for a county, the county clerk. Sending it to the wrong office is a real and recurring problem.
• The window is 90 days, not 90 business days. That can pass while someone is still in physical therapy, long before they have thought about a lawyer.
• Wrongful death claims get six months, a modest extension that still arrives quickly for a grieving family.
• There is an exception where the entity had actual notice of the occurrence, but relying on that exception is a gamble no one should take voluntarily.

Even with timely notice, the suit itself must generally be filed within two years under NMSA § 41-4-15 — a year less than the ordinary deadline — and the Act caps what can be recovered against public entities under NMSA § 41-4-19, with separate limits for medical expenses and other damages and no punitive damages at all. In a state where so much land, road, and infrastructure is publicly managed, the question “is a government entity involved?” should be asked in week one, not month six.

No-fault? Not here

New Mexico is a traditional at-fault (tort) state. There is no personal injury protection requirement and no threshold to sue: the driver who caused the crash is, through their insurer, generally responsible for the harm. That makes evidence of fault the center of gravity in every claim — photographs, the crash report, witness contacts, and prompt medical records all carry real weight.

It also means the other side’s insurer has every incentive to push fault onto you. Remember the pure comparative rule: every percentage point they can pin on you is a point they do not pay. An adjuster’s early, confident assessment of your share of fault is a negotiating position, not a finding. New Mexico’s required liability minimums are also modest, so in serious-injury cases your own uninsured and underinsured motorist coverage often ends up mattering as much as the other driver’s policy — another reason to have someone qualified review the full insurance picture before accepting anything.

New Mexico’s roads earn their reputation

This is not an abstract problem here. According to the Insurance Institute for Highway Safety’s 2024 state data, New Mexico recorded 409 crash deaths — a rate of 19.2 per 100,000 residents, among the highest in the nation. Pedestrians accounted for 90 of those deaths, roughly 22% of the total, an unusually high share. Long rural highway miles, fast urban arterials in Albuquerque, and stretches where pedestrians and traffic mix badly all contribute. If you were hurt walking or cycling, take heart from the fault rule above: even if an insurer insists you “came out of nowhere,” shared fault reduces a New Mexico claim — it does not erase one.

Medical malpractice: caps that change almost every year

If your claim involves medical care, New Mexico is in the middle of a long transition. A 2021 overhaul of the Medical Malpractice Act rewrote the state’s recovery caps under NMSA § 41-5-6, with hospital caps stepping upward every year through 2026 and adjusting for inflation from 2027 onward, and separate inflation-indexed caps for independent providers and outpatient facilities. Past and future medical care and punitive damages generally sit outside the caps entirely, and juries are not told the caps exist. The practical takeaway: what a malpractice claim is subject to depends on when the malpractice occurred and who the defendant is, and as of 2026 those answers keep moving. This is not an area to navigate from a blog post — ours or anyone else’s.
