What makes New Mexico different
If you've been injured in New Mexico, the legal framework that governs your case is fundamentally different from Texas's — even though the two states share a border and many of the same insurance companies operate in both.
The differences aren't minor. They affect how long you have to file, how fault is calculated, how much you can recover, and what evidence you need to preserve from day one. Knowing them is the difference between a case that works and a case that gets quietly destroyed before you ever talk to a lawyer.
Here are the five biggest differences between NM and TX injury law, in plain English:
- Statute of limitations. NM = 3 years. TX = 2 years. (Both can be shorter against government entities.)
- Fault rule. NM = pure comparative fault — recover even at 99% at fault. TX = modified comparative — barred at 51%.
- Government claims. NM = 90-day written notice under the NM Tort Claims Act. TX = 6-month notice under the TTCA, plus damages caps.
- UM/UIM stacking. NM allows stacking of UM/UIM coverage across vehicles and policies. TX prohibits stacking.
- Wrongful death. NM requires a personal representative to bring the claim. TX allows surviving spouse/children/parents to file directly.
The rest of this guide walks through each of those differences in detail — plus a few less-obvious ones that catch even experienced TX lawyers off-guard.
The statute of limitations: 3 years (usually)
Under NMSA 1978 § 37-1-8, personal injury actions in New Mexico must be filed within three years of the date of injury. That's a full year longer than Texas's 2-year statute.
Three years sounds like a lot. It's not. By the time you've gone through emergency treatment, follow-up appointments, physical therapy, an MRI, possibly surgery, and then started trying to settle with insurance — and gotten lowballed for months — you've often eaten 18-24 months of that window before realizing you need to file suit.
And there are big exceptions that shorten the window:
- Cases against government entities (city, county, state, public university, public hospital) require a 90-day written notice under the NM Tort Claims Act — and a 2-year statute for the lawsuit itself. See our deep-dive on the 90-day NMTCA notice.
- Medical malpractice claims have a 3-year statute under NMSA § 41-5-13 but can be tolled in limited circumstances (and there's a Medical Malpractice Act qualified-provider review process).
- Wrongful death = 3 years from death, not from the underlying injury (NMSA § 41-2-2).
- Minors. The 3-year clock doesn't run until they turn 18 (NMSA § 37-1-10) — but this doesn't extend government-entity notice rules.
The takeaway: filing-deadline math in NM is more complicated than it looks. Don't trust the calendar — talk to a lawyer.
The 90-day NM Tort Claims Act notice
This is the single biggest landmine in New Mexico injury law. More good cases die from missing the 90-day notice than from any other procedural defect.
Under NMSA 1978 § 41-4-16, before you can sue any New Mexico governmental entity or public employee acting within scope of duty, you must give written notice within 90 days of the injury or accident.
"Governmental entity" includes:
- The State of New Mexico (and any agency or department)
- Any city or municipality (Albuquerque, Santa Fe, Las Cruces, etc.)
- Any county (Bernalillo, Doña Ana, Lea, etc.)
- Public school districts and the University of New Mexico
- Public hospitals and healthcare facilities
- The New Mexico State Police, City Police, and county Sheriff's Office
- Public utility districts
So if you were hit by a city bus, slipped at a UNM building, treated at a public hospital, or struck by a county vehicle on US-285 — you have 90 days from the date of accident to file written notice with the right agency. Miss that deadline and your case is usually over, regardless of how strong the underlying facts are.
90 days isn't a lot of time.
If your injury involved any government vehicle, government property, government employee, or public hospital — call a lawyer this week. Not next month. The notice must contain specific information about the incident, location, and damages. Read our full guide to NMTCA notice requirements →
Pure comparative fault: Scott v. Rizzo
This is the rule that makes New Mexico more plaintiff-friendly than almost any state in the country.
In Scott v. Rizzo, 96 N.M. 682 (1981), the New Mexico Supreme Court adopted pure comparative fault. Under this rule, you can recover damages no matter what percentage of fault is attributed to you — as long as it's less than 100%.
Compare that to Texas, where you're completely barred from recovery if a jury finds you 51% or more at fault (TX CPRC § 33.001 — the "modified" comparative bar).
How it works in practice:
- NM example. Jury awards $500,000 in damages, finds you 70% at fault. You still take home $150,000 (30% of $500,000).
- TX example, same facts. Jury finds you 70% at fault. You take home zero. The case is gone.
This rule is the reason a marginal liability case that would be unfileable in Texas is a winnable case in New Mexico. It also explains why insurance adjusters in NM work overtime to inflate the victim's fault percentage — every percentage point they tack onto you is a percentage point off the check.
One important nuance: in cases with multiple defendants, NM applies several liability (NMSA § 41-3A-1), meaning each defendant is only on the hook for their own percentage of fault, not the others'. This is different from joint-and-several liability, which still exists in some narrow contexts (intentional torts, products liability, vicarious liability).

UM/UIM stacking — the bonus most TX lawyers don't know about
If you carry uninsured motorist (UM) or underinsured motorist (UIM) coverage on multiple vehicles or under multiple policies, New Mexico law generally allows you to stack those coverages into a single, larger pool of insurance to draw from.
Texas prohibits stacking (since the 1980s reforms). So a Texas driver with UM limits of $30k on three cars has $30k of UM coverage in total. A New Mexico driver with the same setup has $90k.
The leading case is Schmick v. State Farm Mutual Auto Insurance Co., 103 N.M. 216 (1985), which established that intra-policy stacking is allowed unless the insurance company validly rejects it in writing. The follow-on cases — particularly Romero v. Dairyland Insurance, 111 N.M. 154 (1990) — extended that to inter-policy stacking (across separate policies for separate vehicles).
Key NM stacking rules:
- Stacking is the default; rejection must be in writing under NMSA § 66-5-301
- The written rejection must be specific (a generic policy clause won't do)
- If the insurer can't produce a valid written rejection, the stacking applies — full stop
- Stacking applies to UM and UIM equally
This matters most in catastrophic-injury cases. If you've got a $1M jury verdict against an uninsured driver, and you've got $30k of UM on each of four family vehicles — that's $120k recoverable instead of $30k. Full UM/UIM stacking guide here.
Wrongful death in New Mexico
New Mexico wrongful death law has one distinctive procedural feature that trips up most non-NM lawyers: only a personal representative can file.
Under the NM Wrongful Death Act (NMSA § 41-2-1 et seq.), the legal claim doesn't belong to the surviving spouse or kids directly. It belongs to the deceased person's personal representative — who is appointed by the probate court and brings the claim on behalf of all statutory beneficiaries.
Statutory beneficiaries under NMSA § 41-2-3, in order:
- The surviving spouse
- Surviving children (including legally adopted)
- The decedent's father and mother (if no spouse/kids)
- The decedent's siblings (if no spouse/kids/parents)
- Other heirs entitled under intestacy
One consequence: families sometimes file what they think is a wrongful death case in NM, only to be told months later that nothing they did was legally a "filing" — because no personal representative had been appointed yet. The clock keeps running while probate stalls.
Damages in NM wrongful death:
- Value of life — a unique NM measure that compensates for the "intrinsic value" of the lost life (separate from economic loss)
- Economic losses — wages, support, services
- Loss of consortium for the surviving spouse and minor children
- Funeral and burial expenses
- Conscious pre-death pain and suffering (survival damages)

Damages and caps
For private-party defendants, New Mexico has no general cap on compensatory damages — economic, non-economic, or punitive. That's the same as Texas.
But there are several specific contexts where NM does cap damages:
- NM Tort Claims Act cases (against government entities): NMSA § 41-4-19 sets aggregate caps. Currently $1,050,000 for any single occurrence, with sub-caps for property damage ($200k), bodily injury ($300k), and other categories. These caps are inflation-adjusted periodically.
- Medical malpractice cases against "qualified providers" who participate in the Patient Compensation Fund: NMSA § 41-5-6 caps non-economic damages and limits provider liability to $250k per occurrence (with the Fund covering the excess up to total caps).
- Punitive damages: NM has no statutory cap, but punitives require a finding of conduct that's "willful, wanton, malicious, fraudulent, oppressive, or done in bad faith" — a higher standard than the simple negligence required for compensatory damages.
The big takeaway: in straightforward private-party negligence cases (car wreck against a private driver, slip-and-fall against a private store, dog bite against a private homeowner), there are no caps. The jury decides what's fair.
What to do after an accident in NM
If you've been injured in New Mexico, the first 30 days matter the most. Here's a practical checklist:
- Day 1. Get medical attention — even if you "feel fine." Many injuries (TBI, soft-tissue, internal) present hours or days later. The ER visit also creates a baseline medical record.
- Day 1-3. Photograph everything — vehicles, scene, your injuries, the property condition. Get the police report number.
- Day 3-7. Identify whether any government entity may be involved (state highway, city bus, public hospital, public school). If yes — call a lawyer THIS WEEK. The 90-day NMTCA clock is already running.
- Day 7-14. Do not give a recorded statement to the at-fault driver's insurer. Do not sign medical records release. Do not accept any settlement offer.
- Day 14-30. Follow your treatment plan religiously. Gaps in treatment are the #1 evidence insurers use to undervalue claims. Keep an injury journal.
- Throughout. Save everything. Receipts, mileage to appointments, missed-work documentation, prescription records.
And one final thing that's specific to New Mexico: if your accident was on a highway near the Texas border (US-285 near Roswell-Carlsbad, I-40 near the TX/NM line, I-10 near the El Paso border), and you're a Texas resident but the accident happened in NM — your case will likely be governed by NM law. Don't let a Texas adjuster try to apply Texas rules to your NM accident.
Time-sensitive rules in New Mexico mean every week matters.
The 90-day notice rule alone is enough reason to consult an NM-licensed attorney early. The Longhorn Law Firm has attorneys licensed in both Texas and New Mexico — so if your accident crossed state lines, or if you're not sure which law applies, we can help sort it out before any deadlines slip.
