Car insurance claims in New Mexico

New Mexico is an at-fault state, and its shared-fault rule comes from the courts rather than from a statute. Under the Mandatory Financial Responsibility Act «No owner shall permit the operation of an uninsured motor vehicle … upon the streets or highways of New Mexico» and «No person shall drive an uninsured motor vehicle» (§ 66-5-205(A)–(B)), with «uninsured motor vehicle» defined as one for which a policy meeting the requirements of New Mexico law and of the secretary, a surety bond, or a sufficient cash deposit with the state treasurer, is not in effect. The cure is proof IN COURT rather than a grace period at the roadside: a person charged «shall not be convicted if the person produces, in court, evidence of financial responsibility valid at the time of issuance of the citation» (§ 66-5-205(F)) — unlike Nebraska’s ten days or Kansas’s equivalent. The required amounts are $25,000 for bodily injury to one person, $50,000 per accident and $10,000 for property damage, or $60,000 in total if the evidence takes the form of a surety bond or a cash deposit (§ 66-5-208). No amending act after the 1983 recompilation was opened, so those figures are given undated. What is compelled is the ability to respond in damages FOR LIABILITY, which is the positive evidence for at-fault; chapter 66 article 5 was read end to end across fourteen chunks and contains no first-party benefit scheme, but no full-text search of the whole statute book was run and no wider negative is asserted.

Shared fault is judge-made, and this page states the case as characterisation rather than as a verified value. In Scott v. Rizzo, 1981-NMSC-021, 96 N.M. 682, the Supreme Court of New Mexico held that comparative negligence «is adopted in this jurisdiction and replaces the “all-or-nothing” rule of contributory negligence», and went on to hold that «a pure comparative negligence standard shall supersede prior law in New Mexico, and that a plaintiff suing in negligence shall no longer be totally barred from recovery because of his contributory negligence». The opinion was read in full at the New Mexico Compilation Commission’s own platform, the state’s official publisher of the appellate reports — but this dataset records a judge-made comparative rule as verified only from a court-operated host or from GPO, and New Mexico’s court host answers a redirect to 127.0.0.1, so the shared-fault field is left «unclear» rather than filled from a locator the rules do not accept. There is in any event no percentage bar to cite, because there is no statute to put one in: the Legislature simply speaks of «any cause of action to which the doctrine of comparative fault applies» when abolishing joint and several liability (§ 41-3A-1(A)). That abolition matters in its own right. Each defendant’s liability is several, and each pays «only for that portion» of the award equal to the ratio of its own fault «to the total fault attributed to all persons, including plaintiffs, defendants and persons not party to the action» — so the fault of people who are not in the case counts in the denominator. Joint liability survives in four situations, the last of them open-ended: intentional injury, vicarious liability, strict product liability, and «situations not covered by any of the foregoing and having a sound basis in public policy» (§ 41-3A-1(C)). A severally liable defendant gets no contribution and no reduction for what the plaintiff recovered from anyone else (§ 41-3A-1(E)).

The two limitation periods differ, and so do their starting points. An action for injury to the person must be brought within three years (§ 37-1-8); an action for injuries to property within four (§ 37-1-4), and for property the clock does not start until the injury «shall have been discovered by the party aggrieved» (§ 37-1-7) — a rule that section confines to property and conversion and does not extend to the person. Suing on the policy itself, as a written contract, runs six years (§ 37-1-3(A)).

On the insurer’s side New Mexico has one hard deadline, one statutory remedy worth knowing, and one deliberate silence. An insurer that fails for forty-five days after required proof of loss to pay the amount justly due is liable for it with interest at one and a half times the prime lending rate for New Mexico banks, accruing from the forty-sixth day — a FLOATING rate, so no percentage is printed here — and the mechanism does not apply once the claim is in arbitration or litigation (§ 59A-16-21(B)–(C)). A claim cheque, draft or electronic transfer that is not paid or lawfully rejected within ten days of forwarding by a New Mexico financial institution gives a New Mexico resident «a cause of action for ten percent of the amount», «in no case to be less than five hundred dollars ($500) plus costs of suit and attorney fees», with a defence where the delay was the fault of a financial institution or a delivery service and the instrument was honoured «within forty-eight hours of actual receipt» (§ 59A-16-21(A)). Found in no other state in this dataset. NEW MEXICO HAS NO ACKNOWLEDGEMENT OR DECISION DEADLINE FOR A MOTOR CLAIM, AND THIS PAGE STATES THAT AS A FINDING. The unfair-claims-practices section requires only that an insurer «acknowledge and act reasonably promptly» upon communications and «affirm or deny coverage of claims of insureds within a reasonable time» after proof of loss, its duties run to INSUREDS throughout rather than to third-party claimants, and the single day count it does contain — ninety days — is for claims under a DECLARED CATASTROPHIC LOSS and must not be borrowed for an ordinary motor claim (§ 59A-16-20). The section was amended twice in 2025, by Laws 2025, ch. 120, § 1 and ch. 127, § 10; neither act was opened. And the Administrative Code was searched rather than assumed: the publisher’s own search over the whole of NMAC Title 13 returns thirty-nine hits for «acknowledge», all thirty-nine were read, and every timed acknowledgement duty among them is a health-grievance or a filing rule — none imposes a deadline on a property or casualty claim. That is a different situation from a blocked host, and the fields are left empty on the strength of it.

Uninsured and underinsured motorist cover must be in every New Mexico policy at the § 66-5-215 minimum limits and up to the insured’s own liability limits, and NEW MEXICO’S UM COVER REACHES PROPERTY DAMAGE as well as bodily injury — the only state in this dataset where it does, so nothing about it should be generalised from Iowa, whose Division mandates a policy notice saying the opposite. UIM sits inside the UM cover and is defined by comparison with the insured’s OWN uninsured-motorist limit, not with the state minimum (§ 66-5-301(A)–(B)). The statute allows an exclusion «of not more than the first two hundred fifty dollars ($250)» of property loss, and gives the named insured «the right to reject uninsured motorist coverage», with a written request needed to restore it at renewal (§ 66-5-301(C)). A divergence is recorded here rather than resolved: the statutory text attaches the writing requirement to the REQUEST to restore the coverage, while the Superintendent’s own rule treats a rejection as one «required in writing by the provisions of Section 66-5-301 NMSA 1978» and requires it to «be endorsed, attached, stamped or otherwise made a part of the policy» (13.12.3.9 NMAC). The safe published form is the regulation’s — a rejection must be in writing and made part of the policy — attributed to the rule and not to the statute. The prescribed endorsement is a floor and not a ceiling: nothing stops an insurer filing an endorsement more favourable to the policyholder (13.12.3.8 NMAC).

Reporting is stricter in New Mexico than in the states around it. The driver must give name, address and registration number, exhibit the licence on request, and «render to any person injured in such accident reasonable assistance» — triggered by injury, death, or damage to any vehicle «driven or attended by any person» (§ 66-7-203). New Mexico does not require the insurer’s name at the scene, unlike Kansas. Police must be notified «immediately, by the quickest means of communication» of any crash causing bodily injury, death «or property damage to an apparent extent of five hundred dollars ($500) or more» — the lowest dollar trigger in its round (§ 66-7-206, which a 2021 act extended to autonomous-vehicle operators). A written report must go to the Department of Transportation «within five days after the accident» on the same trigger, AND — unlike Iowa and Nebraska, which both excuse the driver’s report where a law-enforcement agency investigated — § 66-7-207(A) contains no such exemption, while subsection (C) adds the investigating officer’s own report within twenty-four hours of completing the investigation on top. Where the driver is physically incapable and is not the owner, the owner files within five days of learning of the crash (§ 66-7-208(B)). Colliding with an unattended vehicle requires stopping and either finding the owner or leaving a written notice, with no duty to notify police (§ 66-7-204). Whether inherent diminished value is recoverable in New Mexico has not yet been verified against a primary text and is not stated here, and this page claims NO regulatory negative on the question either: the Administrative Code search described above was run for «acknowledge», not for diminution language, so unlike Iowa and Nebraska there is not even a searched silence to report.
