New Mexico’s 3-Year Injury Deadline: The Rule, the Exceptions, and the Traps

Three years. That is how long you have to file a lawsuit for most personal injuries in New Mexico, counted from the date of the injury, under NMSA 1978, Section 37-1-8. It sounds like plenty of time, and for the paperwork it is. The trouble is that the three-year rule has exceptions running in both directions, and one of them can shrink your window to 90 days without anyone warning you.

This article covers the rule, the two big exceptions (injured children get more time, claims against the government get dramatically less), and the traps that catch people who assume the deadline is the only clock running.

Where does the three-year rule come from?

Section 37-1-8 sets a three-year limitations period for actions «for an injury to the person,» which covers the core of personal injury law: car crashes, motorcycle and truck collisions, pedestrian injuries, and most other negligence claims. The clock starts when the cause of action accrues, which for a traffic crash means the date of the crash itself. It does not restart when you finish treatment, when the insurer denies your claim, or when you finally hire a lawyer.

Miss the deadline and the case is over before it starts. A defendant raises the statute of limitations, the court dismisses the suit, and every dollar of leverage you had in negotiation disappears with it, because an insurer has no reason to pay a claim that can never reach a jury. Wrongful death claims run on their own three-year clock under NMSA 1978, Section 41-2-2, measured from the date of death rather than the date of the crash, and New Mexico courts treat that one as a limit on the right itself. Our New Mexico wrongful death guide covers how those cases differ.

What if the injured person is a child?

New Mexico tolls the deadline for minors. Under NMSA 1978, Section 37-1-10, a person who was under 18 when injured has until one year after their eighteenth birthday to file, or the standard three years, whichever gives them more time. A ten-year-old hurt in a crash today can, in theory, still file suit at nineteen.

In theory is doing heavy lifting in that sentence. Waiting nine years means the witnesses have moved, the vehicles are long gone, the intersection has been rebuilt, and the defense will argue that every gap in the record is your problem. The tolling statute protects a child’s right to sue; it does nothing to preserve the evidence a winning suit is built from. Families are almost always better served by investigating immediately and using the extra time as insurance rather than as a plan.

What changes when the government is involved?

Everything. If the vehicle that hit you was a city bus, a police cruiser, a school activity van, or a state road maintenance truck, your claim falls under the New Mexico Tort Claims Act, and the friendly three-year rule no longer applies to you.

Two separate clocks start. First, under NMSA 1978, Section 41-4-16, you must present a written notice of claim within 90 days of the occurrence, stating the time, place, and circumstances of the injury. The notice goes to a specific recipient: the risk management division for claims against the state, the mayor for claims against a city, the county clerk for a county, the school superintendent for a school district. For wrongful death claims the notice period extends to six months. Second, under Section 41-4-15, the lawsuit itself must be filed within two years, not three.

The statute contains narrow escape hatches: the notice period excludes time (up to 90 days) during which the injured person was incapacitated, and a suit can survive a missing notice if the government entity had actual notice of the occurrence. Courts read those exceptions narrowly, and betting your case on one is a bad trade when a certified letter inside 90 days settles the question. If there is any chance a public entity is involved, treat the deadline as 90 days and act accordingly.

Why does evidence die before deadlines do?

The statute of limitations is the last date to file a lawsuit, not the last date your case can be won or lost. That happens much earlier, in the weeks when the evidence either gets preserved or quietly disappears.

Surveillance and traffic camera footage typically overwrites on cycles measured in days or weeks. Commercial trucking companies must retain electronic logging device records for at least six months under federal rules, and after that the fatigue evidence in a truck case can be gone lawfully. Vehicles are repaired or totaled and crushed, taking their event data with them. Skid marks fade. Witnesses change phone numbers, move out of Albuquerque, and merge the crash into the general blur of memory. A case filed at two years and eleven months with none of that evidence is technically timely and practically hollow.

What are the traps that catch people?

Most blown deadlines are not procrastination; they are misplaced trust in a process that was never designed to protect the claimant. The patterns repeat:

1. Negotiating past the deadline. Talking to an adjuster does not pause the clock. Insurers know the filing date better than you do, and slow-walking a friendly negotiation until the statute runs is a known move.
2. Missing the government notice. The 90-day Tort Claims Act notice expires while most people are still in physical therapy, long before anyone thinks the word «lawsuit.»
3. Waiting to finish treatment. You can and should account for future medical care in a claim; you cannot wait years for maximum recovery before starting one.
4. Assuming one deadline fits every claim. Injury, wrongful death, and government claims each run on different clocks, and a single crash can trigger more than one of them.
5. Leaving no runway. A well-built lawsuit needs investigation, records, and often expert review before filing. Arriving at a law office the month the statute runs limits what anyone can do for you.

Deadline questions, answered

Is the deadline paused while the insurance company reviews my claim?

No. Claim negotiations, medical record requests, and settlement talks have no effect on the statute of limitations. The three-year period under Section 37-1-8 keeps running through all of it. If a resolution is not signed before the deadline, the suit must be filed to preserve the claim, even if negotiations continue afterward.

What happens if I file one day late?

The defendant moves to dismiss, and absent a recognized exception the court grants it, regardless of how strong the underlying case was. New Mexico courts apply limitations periods strictly. One day late is treated the same as one year late, which is why lawyers file with margin instead of testing the boundary.

Can I still act if the crash happened more than two years ago?

Usually yes, if no government defendant is involved. A standard injury claim remains viable until the three-year mark, though the remaining runway limits how much investigation can happen before filing. Bring whatever records, photographs, and correspondence you have, and a lawyer can assess quickly whether the timeline still works.

Does the 90-day government notice apply to children?

New Mexico courts have declined to enforce the notice requirement against minors who cannot reasonably give notice themselves and have no one able to do it for them. It is a fact-specific protection, not a blanket exemption, so families should still send notice immediately rather than rely on a court finding the exception later.
