Statute of Limitations for Class A / 1st Degree Felony in Montana

5 min read

Published March 22, 2026 • By DocketMath Team

Overview

In Montana, the statute of limitations (SOL) sets the deadline for the state to file criminal charges after an alleged offense. For a Class A / 1st Degree felony, many people assume there’s a special deadline tailored to that exact charge level. In practice, Montana’s criminal SOL framework can be narrower and more nuanced depending on the offense and the procedural posture of the case.

For purposes of DocketMath’s statute-of-limitations calculator, this page describes the general/default criminal SOL period applicable under Montana’s general limitations statute. Per the jurisdiction data provided:

  • General SOL period: 3 years
  • General statute: **Montana Code Annotated (MCA) § 27-2-102(3)
  • No charge-specific sub-rule found: The calculator uses this general rule as the default when no more specific rule is identified.

Note: This article summarizes the general/default SOL referenced by MCA § 27-2-102(3). If your situation involves a different statute, tolling rule, or a more specific limitations provision tied to a particular offense type, the deadline can change.

Limitation period

Default deadline: 3 years

Using the general rule provided for Montana:

  • The default SOL period is 3 years, counted from the relevant trigger described in the statute (generally tied to when the offense is committed, unless the law specifies otherwise for a particular situation).

Because this page is aimed at a Class A / 1st Degree felony, the key takeaway is straightforward:

  • If no specific exceptions or alternate limitations provisions apply, the general/default deadline to bring the case is 3 years.

What the 3-year period means in calendar terms

A practical way to think about it:

  • Identify the date of the alleged offense
  • Add 3 years
  • The prosecution must be initiated within that resulting time window (subject to any exceptions discussed below)

Because limitations calculations are sensitive to the precise dates, DocketMath’s calculator is built to turn these dates into an output you can use for case triage and deadlines tracking.

How DocketMath outputs change with inputs

DocketMath’s statute-of-limitations tool typically relies on inputs like:

  • Alleged offense date (the “start”)
  • Potential adjustment inputs (depending on the scenario)

When you enter different offense dates, the deadline moves accordingly:

  • Move the offense date forward by 60 days → the expiration date moves forward by about 60 days.
  • Move the offense date back by 1 year → the expiration date moves back by about 1 year.

If you select fewer “adjustment” options (or none), you’ll generally see the clean default 3-year endpoint. Add exceptions/tolling where supported by the tool logic, and the output may extend the deadline—however, the exact availability of those toggles depends on what DocketMath models for Montana.

Key exceptions

Montana SOL computations can be affected by legal doctrines that alter either:

  1. the start date (when the clock begins), or
  2. the running of time (whether the clock pauses or resets).

Since this page is anchored to the general/default rule in MCA § 27-2-102(3) and explicitly notes that no charge-specific sub-rule was found in the provided jurisdiction data, the “exceptions” section focuses on what to look for before relying on the plain 3-year period.

Common categories that often matter in criminal limitations analysis include:

  • Tolling events (situations where time does not count in the normal way)
  • Fugitive-related or concealment-related doctrines (where applicable)
  • Statutory triggers different from the offense date (where a statute defines a distinct starting point)
  • Procedural facts that affect when the state’s action counts as “commenced”

Warning: Don’t assume the 3-year number is automatically controlling for every “Class A / 1st Degree felony” fact pattern. If tolling, a different statutory trigger, or another limitations provision applies, the deadline can be longer than the default.

Practical checklist before using the default

Before you treat the 3-year endpoint as definitive, confirm these items:

Even if DocketMath uses the general/default rule, this checklist helps you decide whether the output should be treated as a baseline only.

Statute citation

Montana general/default statute of limitations (provided):

  • MCA § 27-2-102(3)3-year SOL period (general/default)

The jurisdiction data also notes:

  • No claim-type-specific sub-rule was found for this page’s stated scenario.
  • Therefore, this page uses MCA § 27-2-102(3) as the default rather than claiming a special Class A / 1st Degree-specific rule.

Use the calculator

Use DocketMath to generate a concrete limitations deadline from the default rule.

Primary CTA: ** /tools/statute-of-limitations

Steps

  1. Open DocketMath → Statute of Limitations:
    /tools/statute-of-limitations
  2. Enter the alleged offense date (the baseline for the 3-year clock).
  3. Review the output showing the default expiration date under the 3-year period.
  4. If the tool offers scenario/tolling options relevant to your facts, select only those that accurately match the case timeline. Otherwise, leave them off and treat the result as a baseline.

Outputs to expect

Typically, you’ll see at least:

  • Default SOL length: 3 years
  • Calculated expiration date: Offense date + 3 years
  • Notes on adjustments: If applicable inputs extend or modify the timeline

Note: If your case facts include tolling or a different statutory trigger, the calculator may need additional inputs (or may not reflect that complexity). When in doubt, treat calculator output as a starting point for deadline tracking, not a final legal determination.
