About This Calculator
This calculator finds your exact filing deadline for a personal injury claim in Montana. It applies Montana's specific statute of limitations period, checks whether the discovery rule extends your deadline, accounts for tolling if the injured party was a minor, and flags any special notice requirements if your claim involves a government entity. Enter your incident date — or discovery date if the harm wasn't immediately apparent — and the calculator counts forward using Montana's exact rule to show your filing deadline, the time remaining, and an urgency status. Results are based on verified state statute citations, not general estimates.

How Montana's Personal Injury Deadline Works
Under Montana Rev. Stat. § 71, Montana provides 3 years to file a personal injury lawsuit. The clock typically begins when the injury was discovered — or when it reasonably should have been discovered — rather than on the date the harm occurred. This is known as the discovery rule. Montana extends the filing window by up to 1 additional year under the discovery rule.
Montana's personal injury statute of limitations is governed by the state's civil procedure and limitations statutes. Claims against state agencies, municipalities, or other government entities in Montana may require filing a formal notice of claim before suit can be commenced — notice deadlines vary by entity type and are often shorter than the civil filing deadline. Under state law, the limitations period is tolled for minor claimants until they reach the age of majority at 18.
Special Circumstances
Government entity claims: If the defendant is a government entity, Montana requires a formal administrative claim notice to be filed within 6 months of the incident before a lawsuit may be filed. Missing this notice deadline permanently bars the claim. After the claim is rejected, you have 12 months to file suit.
Minor claimants: If the injured person was a minor at the time of the incident, Montana tolls the statute of limitations until they reach age 18.
What Happens If You Miss the Deadline
If a lawsuit is filed after the statute of limitations expires, the defendant can ask the court to dismiss the case as time-barred — and courts almost always grant this motion, regardless of how strong the underlying claim is. The right to sue is lost permanently; there is no general exception for not knowing the deadline existed. A small number of circumstances can pause or extend the clock, covered in the Special Circumstances section above if they apply to your claim type and state. If your deadline is approaching or may have already passed, contact a licensed attorney immediately — some exceptions are themselves time-sensitive.
Frequently Asked Questions
How does minor tolling affect personal injury deadlines in Montana?
Montana law tolls the personal injury statute of limitations for minors, pausing the clock until they reach age 18. However, Montana places a strict overall cap on this tolling period, limiting how long the deadline can be extended regardless of the child's age. Once they turn 18 or the cap is reached, the standard filing window commences.
Are medical malpractice cases subject to Montana's personal injury deadline?
Medical malpractice claims in Montana are governed by a distinct statute of limitations. Furthermore, plaintiffs must submit their claims to the Montana Medical Legal Panel for mandatory review before a lawsuit can be filed in district court. General personal injury timelines are inapplicable to healthcare negligence.
What happens if a personal injury leads to death in Montana?
If an injury proves fatal, the case converts to a wrongful death and survival action under Montana law. The deadline for this claim is separate and generally begins on the date of death. The personal representative brings the action to recover damages for both the estate and the heirs.
How does Montana apply the discovery rule to personal injuries?
Montana recognizes the discovery rule for personal injuries where the facts constituting the claim are concealed or self-concealing. The clock is paused until the plaintiff discovers, or reasonably should have discovered, the injury and its cause. This is vital in cases of toxic exposure or latent disease.
What notice is required to sue a government entity in Montana?
Under the Montana Tort Claims Act, you cannot immediately sue a government entity. Plaintiffs must first present a formal administrative claim to the Department of Administration. The state then has a specific period to review and potentially deny the claim before a civil lawsuit can be initiated.
