Filing Deadlines Under Minnesota Law
A limitation period is the time the law allows for starting a lawsuit. A claim started after it runs out is generally barred, so this is the rule with the most at stake.
Section 541.05 of the Minnesota Statutes sets a six-year period, except where the Uniform Commercial Code otherwise prescribes, for actions "for criminal conversation, or for any other injury to the person or rights of another, not arising on contract, and not hereinafter enumerated." The text of section 541.05 is on the Revisor of Statutes site.
The same section sets a shorter period for product claims: "Unless otherwise provided by law, any action based on the strict liability of the defendant and arising from the manufacture, sale, use or consumption of a product shall be commenced within four years."
For children, section 541.15 of the Minnesota Statutes suspends a limitation period while the plaintiff is under 18, until that disability is removed. For disabilities other than infancy, the extension is capped at five years, and in any case the period may not be extended more than one year after the disability ends. Its text on minors and other disabilities also has a separate health care rule that does not concern park injuries.
When a municipality is involved, section 466.05 of the Minnesota Statutes requires a notice of claim to its governing body "within 180 days after the alleged loss or injury is discovered." The notice states the time, place and circumstances, the names of municipal employees known to be involved, and the compensation or other relief demanded. Actual notice of sufficient facts to reasonably put the governing body or its insurer on notice of a possible claim counts as compliance. Omitting an amount does not invalidate the notice, but the claimant must then provide full information on the injuries and damages within 15 days after the municipality demands it. The time does not include any period the injured person is incapacitated by the injury from giving notice. For a wrongful-death claim, the notice may be presented by the personal representative, surviving spouse, next of kin, or the consular officer of the deceased's country of citizenship, within one year after the injury or loss resulting in the death. The text of section 466.05 sets out both rules.
Which period applies, and when it began, depends on the theory, the parties and the injured person's age. If a city-run site or a product may be involved, the shorter periods are the ones to weigh first. Confirming the applicable dates is a common first topic with an attorney.
