The rule, in two sentences

New Mexico is a pure comparative fault state. That means an injured plaintiff can recover damages no matter what percentage of fault is attributed to them — provided the plaintiff is not 100% at fault — with the recovery reduced by their own fault percentage.

If a jury finds you 1% at fault, you get 99% of the damages. If a jury finds you 99% at fault, you still get 1% of the damages. The only outcome that bars recovery entirely is a finding of 100% at fault — which is rare, because it usually means the defendant has no liability at all.

Where the rule came from: Scott v. Rizzo

The rule comes from Scott v. Rizzo, 96 N.M. 682, 634 P.2d 1234 (1981) — a decision of the New Mexico Supreme Court that abolished the old common-law rule of contributory negligence (which barred any plaintiff who was 1% at fault from recovering anything).

The Court rejected the "all or nothing" approach of contributory negligence as fundamentally unfair, and replaced it with pure comparative fault — the most plaintiff-favorable comparative-fault rule available. Only a handful of other states have followed New Mexico's lead, including California, Florida, and New York.

Compare that to Texas, which kept a "modified" comparative-fault rule under TX CPRC § 33.001: plaintiffs are completely barred from recovery if they're 51% or more at fault. The same conduct that nets a $50,000 check in NM nets zero in TX.

Worked examples

Let's make the rule concrete with three scenarios.

Scenario 1: Rear-end collision in Albuquerque

You're rear-ended on I-25. The other driver was distracted; you'd had a beer earlier (.04 BAC, under the limit). Jury finds you 20% at fault for slow reaction time. Damages = $200,000.

NM result. You recover $160,000 ($200k × 80%).

TX result. You recover $160,000 (same — under the 51% threshold, the formula is the same).

Scenario 2: Motorcycle wreck on US-285

You're hit by a left-turning driver who failed to yield. But you were going 65 in a 55 zone, and the jury finds you 55% at fault for excessive speed. Damages = $400,000.

NM result. You recover $180,000 ($400k × 45%).

TX result. You recover $0 — the 51% bar wipes you out entirely.

Scenario 3: Slip-and-fall at a Santa Fe hotel

You slip on a wet lobby floor that wasn't marked with caution signs. But you were walking while looking at your phone. Jury finds you 70% at fault. Damages = $100,000.

NM result. You recover $30,000 ($100k × 30%).

TX result. You recover $0.

Why insurance adjusters in NM try to inflate your fault

If you understand the math, you understand the strategy. Every percentage point of fault that the insurance company can pin on you is a percentage point off the check.

So in New Mexico, adjusters don't necessarily fight liability altogether — they fight to push your fault percentage upward. A 20% fault attribution in NM is a $40,000 swing on a $200,000 case.

Common tactics:

  • "You were on your phone right before impact." (Even when you weren't.)
  • "You were speeding." (Based on accident reconstruction that's often unreliable.)
  • "You didn't take evasive action." (Even when no evasive action was possible.)
  • "You should have known the floor was wet." (When there's no warning.)
  • "You weren't wearing a seatbelt." (Generally not admissible as fault evidence in NM, but used to pressure settlements.)

This is one of the reasons evidence preservation matters so much in NM cases. Photos, witness statements, dashcam footage, GPS data — anything that shows you weren't doing what they're going to claim you were doing — is worth a lot of money.

Multi-defendant cases: several liability

When there's more than one defendant — say, a drunk driver and the bar that overserved him, or a trucking company and the maintenance contractor — New Mexico uses several liability (NMSA § 41-3A-1).

Under several liability, each defendant is only liable for their own percentage of fault, not the percentages assigned to other defendants. If a $1M verdict is split 70% to Defendant A and 30% to Defendant B, each defendant pays their own share.

This is different from joint and several liability, where any defendant could be made to pay the entire verdict (and would then have to seek contribution from co-defendants).

NM keeps joint-and-several liability for a few specific categories:

  • Intentional torts (assault, battery, defamation)
  • Strict products liability claims
  • Vicarious liability (where one party is legally responsible for another's acts — like an employer for an employee)
  • Cases where the defendants were engaged in a "common-plan" enterprise

The practical result: in most NM cases, you need to sue every defendant who might have any percentage of fault, and you need to be able to actually collect from each of them. A judgment against a bankrupt or insolvent defendant is worth nothing under several liability.

Why this rule changes what cases are filable

Because of pure comparative fault, certain cases that would be unfileable in Texas are highly filable in New Mexico:

  • A motorcyclist hit by a car while lane-splitting (a maneuver where the rider's fault could easily be set at 60%+)
  • A pedestrian hit while crossing outside a marked crosswalk
  • A driver who ran a yellow-turning-red light and was T-boned
  • A bar patron who was drunk and slipped on a wet bathroom floor
  • A worker who was injured while not wearing the safety equipment required by his employer

In each of these scenarios, the plaintiff probably has some real fault — maybe even majority fault. In Texas, that ends the case. In New Mexico, it just affects the math.

This is the single most important reason why NM is more plaintiff-friendly than its neighbors. It's also why insurance companies fight harder on fault attribution in NM than they do anywhere else.
