Montana Gives You Three Years to File an Injury Claim. Don't Plan on Using Them All.

On paper, Montana is one of the friendlier states in which to bring an injury claim: three years to file where most states allow two, a rule that lets you recover even when you share half the blame, and a ban on the insurance industry’s favorite seat belt argument. The catch is that the friendly headline hides deadlines and rules that are far less forgiving.

Start with the deadline — and its exceptions

Montana’s general rule, found in MCA 27-2-204, gives you three years to file a lawsuit for most injuries caused by negligence — car crashes, slip and falls, and similar claims. That is a full year longer than the two-year window that states like Nevada, Texas, and California use, and it is one of the reasons injured Montanans sometimes assume they have plenty of time.

But the same statute contains a trap: claims based on intentional conduct — assault, battery, false imprisonment — generally must be filed within two years, not three. If you were hurt in a bar fight in Billings rather than a fender-bender on I-90, your clock may be a year shorter than you think. Wrongful death claims generally carry a three-year period as well, and Montana law extends that window substantially — to ten years — when the death resulted from a homicide.

One more wrinkle: the 2025 Legislature amended this statute, and an updated version of its text takes effect in late 2026. The core three-year rule remains, but details around the edges are in motion, which is exactly why the safe move is to confirm your specific deadline with a licensed Montana attorney rather than counting on a blog post — ours included.

The 50 percent line that decides everything

Montana follows modified comparative negligence under MCA 27-1-702. In plain terms: you can still recover compensation as long as your share of the fault was not greater than the combined fault of everyone you are seeking recovery from. Your compensation is then reduced by your percentage of the blame.

So a Montanan found 30% responsible for a crash generally still has a claim — reduced by that 30%. Even at exactly 50%, recovery is still possible. But at 51%, the claim is barred entirely. Nothing.

That cliff is why the percentage assigned to you is the most contested number in a Montana injury case, and why you should treat an adjuster’s early opinion about your fault as a negotiating position, not a verdict. Insurance companies know exactly where the 51% line sits, and pushing your share of blame toward it is the cheapest way to shrink — or erase — what they owe.

Fault matters because Montana is an at-fault state

Montana is not a no-fault state. There is no personal injury protection requirement and no injury threshold you must clear before bringing a claim. The driver who caused the crash — through their liability insurance — is generally responsible for the harm, which makes the evidence of who did what central from day one.

The practical problem is that Montana’s required minimum liability coverage is modest, and the state’s driving conditions are not: long stretches of high-speed two-lane highway, winter ice, wildlife on the road, and serious distances between a crash site and a trauma center. Severe crashes on rural roads can easily involve harm that outruns a minimum policy. That is why it is worth reviewing your own uninsured and underinsured motorist coverage now, before you ever need it, and why identifying every available policy after a crash — the driver’s, a vehicle owner’s, an employer’s, your own — is one of the first things a lawyer will do.

The seat belt argument insurers cannot make here

Here is a rule that surprises out-of-state insurers: under MCA 61-13-106, evidence that you were or were not wearing a seat belt is not admissible in a Montana civil case arising from a motor vehicle crash, and failure to buckle up does not constitute negligence. The statute has been on the books since 1987.

In many states, insurers argue that an unbelted injured person should absorb part of the blame for their own injuries. Montana law generally takes that argument off the table. If an adjuster hints that your claim is worth less because you were not wearing a seat belt, they are reciting another state’s playbook — and it is a strong signal you should have someone qualified handling the conversation.

Hurt by a government vehicle or on public property? Different playbook

Claims against the State of Montana, a county, or a city follow their own procedure. Under MCA 2-9-301, a claim against the state generally must first be presented in writing to the Department of Administration before a lawsuit can be filed, and claims against local government entities must be presented to the clerk or secretary of that entity. The department then has 120 days to grant or deny the claim — and silence counts as a denial. Filing the claim also tolls the statute of limitations for 120 days while the review runs.

These procedural steps are unforgiving, and getting them wrong can sink an otherwise valid case. If your injury involves a snowplow, a public school, a state highway defect, or any government actor, treat it as a specialty problem and get Montana counsel involved early.

What the 2025 Legislature changed

Montana caps noneconomic damages — pain, suffering, emotional distress — in medical malpractice cases under MCA 25-9-411. In 2025, the Legislature raised that cap and put it on a schedule of annual increases running through the end of the decade, with inflation-style adjustments after that. The specific figure now depends on when your claim resolves, so it is a number to confirm with an attorney rather than assume from an older article.

Two things worth understanding about the cap: it applies to medical malpractice claims, not to car accidents or other ordinary negligence cases, and it does not limit compensation for economic losses like medical bills and lost income. How caps interact with the value of any particular claim is genuinely case-specific — we walk through the general factors in what goes into an injury claim’s value.

What this means if you were hurt in Montana

The three-year window is real, but it measures when a lawsuit must be filed, not when you should start. Skid marks fade, ranch-road witnesses scatter, vehicles get repaired or scrapped, and insurance policies often require notice within days or weeks of a crash. As of 2026, the smart sequence looks the same as ever:

• Get medical care promptly and keep the records. A documented visit ties the injury to the incident; a long gap invites the argument that something else caused it.
• Report the crash and preserve evidence. Photos, names, the police report, and the vehicles themselves before they are repaired or scrapped.
• Identify every potentially involved party early. Especially if a commercial truck, a ranch or oilfield vehicle, or a government entity is in the picture.
• Find out where you stand before the evidence decides for you. Waiting costs leverage even when the deadline is years away.
