Understanding New Mexico's Three-Year Filing Deadline
New Mexico is more generous than most states about how long you have to file an injury claim: three years, where California and Arizona allow two. That extra year is real — and it is also the reason a much shorter deadline sitting inside New Mexico law catches so many people out.
Three years for most crash claims
For most New Mexico injury claims, you generally have three years from the date of injury to file suit. If you have been reading national advice built around a two-year rule, that is the norm elsewhere, not here.
Ninety days when a government entity is involved
The Tort Claims Act governs any claim against a state agency, a county, a city, a public school, or a public employee — and it requires written notice within 90 days, with suit within two years. Ninety days is the shortest deadline in New Mexico injury law, and it can expire while someone is still in the hospital.
Medical claims run on a different rule entirely
If a claim involves medical care, do not assume the three years applies. Claims against providers qualified under the Medical Malpractice Act are governed by a statute of repose that can run from the date of the treatment itself rather than from when the harm was discovered — a materially different rule with a harder edge.
The extra year is not a reason to wait
Three years is how long you have to file, not how long the proof lasts. On New Mexico's rural highways, where crashes often happen without cameras or witnesses, the physical evidence and the vehicles themselves are what carry a case — and none of that survives three years.
Frequently asked questions
How long do I have to file a car accident claim in New Mexico?
Generally three years from the date of the crash — longer than in California or Arizona. Claims against government entities and claims involving medical care follow different, shorter rules.
Why is the government deadline so much shorter?
The Tort Claims Act sets its own notice requirement — 90 days — as a condition of suing a public entity at all. It applies regardless of how serious the injury is, which is why these claims need attention immediately.
