The short answer
- You generally have 3 years to file a lawsuit. N.M. Stat. §37-1-8.
- New Mexico uses pure comparative negligence — no fault bar. Even if you're 90% at fault, you can still recover something.
- New Mexico is an at-fault, tort-based state. No PIP requirement — the at-fault driver's insurance covers injuries directly.

New Mexico’s rules are genuinely claimant-friendly: a three-year window and a fault rule with no cutoff at all, similar to states like California and Arizona.
Only when a New Mexico court finds you 100% at fault does the door close entirely — any lower share, and you still recover something.

How long do I have to file a car accident lawsuit in New Mexico?
Under N.M. Stat. §37-1-8, you generally have three years from the date of the accident to file a personal injury lawsuit. Claims against a government entity are shorter — a 90-day notice requirement, and a two-year deadline for civilian claimants.
What if I was partly at fault in New Mexico?
New Mexico uses pure comparative negligence: your damages are reduced by your percentage of fault, but there is no cutoff. Even if you’re found 90% at fault, you can still recover the remaining 10% — only a finding of 100% fault eliminates recovery entirely.
- Found 15% at fault → you recover 85% of your damages
- Found 90% at fault → you still recover the remaining 10%
- Only 100% fault bars recovery entirely
What car insurance does New Mexico require?
New Mexico is an at-fault, tort-based state — unlike some neighboring states, there’s no PIP requirement, and the at-fault driver’s liability insurance covers injuries directly. Minimum liability limits are 25/50/10: $25,000 per person and $50,000 per accident for bodily injury, plus $10,000 for property damage.

How this plays out in a real claim
Take a rear-end collision where the trailing driver was following too closely, but the lead driver’s brake lights weren’t working. An insurer might assign 70% fault to the trailing driver and 30% to the lead driver. Because New Mexico follows pure comparative negligence, the lead driver’s compensation is reduced by their 30% share — not eliminated by it, and not eliminated even if their share were 90%. This is also why insurers in New Mexico tend to focus heavily on negotiating your fault percentage upward, rather than trying to push you past a bar that doesn’t exist here.
What mistake should I avoid after a crash in New Mexico?
Because New Mexico’s rule has no bar at all, some people assume a high fault percentage means there’s no point pursuing a claim. That’s rarely true here — even a driver found 80% or 90% at fault can still recover their remaining share, so it’s worth having the claim properly valued rather than assuming a disputed-fault situation isn’t worth pursuing.
What if a government vehicle or agency was involved?
Under the New Mexico Tort Claims Act, you must file written notice within 90 days of the accident (NMSA §41-4-16) with the correct office — the Risk Management Division for a state claim, or the relevant mayor, county clerk, or school district superintendent for a local one. This is separate from, and much shorter than, the two-year deadline to actually file the lawsuit (NMSA §41-4-15). Damages against the government are also capped by statute, at figures well below what an uncapped claim against a private driver could recover — worth confirming the current amount directly given how specific and frequently-cited these caps are.
What is the deadline if the crash caused a death?
New Mexico gives three years from the date of death for a wrongful death claim (N.M. Stat. §41-2-2), filed only by the estate’s personal representative. New Mexico courts have specifically declined to apply a discovery rule to this deadline, so it runs strictly from the date of death even if the fatal cause wasn’t immediately apparent. Distribution follows a set order: spouse alone if there are no children; split evenly between spouse and children/grandchildren if both survive; children or grandchildren alone if there’s no spouse; then parents; then siblings.
Beyond the deadline and the fault rule
The statute of limitations and the fault rule above decide whether you have a claim and how much of it survives — they don’t decide what the claim is actually worth, or whether it’s worth handling yourself. For that, see our guides on what affects a settlement, who pays your medical bills while a claim is pending, and whether New Mexico law makes a lawyer worth it for your specific situation.
