Statute of Limitations for Class C / 3rd Degree Felony in Montana
5 min read
Published March 22, 2026 • Updated April 8, 2026 • By DocketMath Team
Overview
In Montana, the statute of limitations (SOL) for a Class C / 3rd degree felony is generally 3 years, based on Montana Code Annotated (MCA) § 27-2-102(3).
Practically, the SOL sets a deadline for the State to file or prosecute a criminal case after an alleged offense. DocketMath’s SOL calculator can help you convert that deadline into a specific date you can track—by using the date the tool uses as the starting point (often the date of the alleged conduct, depending on what you select in the calculator) and then applying the baseline Montana SOL rule.
Note: This article summarizes Montana’s general/default SOL period. It is not a substitute for legal advice and does not cover every possible fact-specific adjustment that could arise in a real prosecution.
Limitation period
Montana’s default/general SOL period is 3 years, per MCA § 27-2-102(3). The content brief you provided also indicates that no claim-type-specific sub-rule was found, so treat § 27-2-102(3) as the baseline for this page.
What a “3-year SOL” usually means (timing)
A “3-year SOL” typically means the State must begin prosecution within 3 years from the triggering event. In many everyday calculations, the triggering event is treated as the date of the alleged offense, but real-world timing can vary based on procedure and the specific starting-date rules reflected in the calculator.
Here’s a simple sanity-check timeline (using the alleged offense date as the start date):
| Alleged offense date | Default SOL deadline (3 years later) |
|---|---|
| Jan 15, 2020 | Jan 15, 2023 |
| May 1, 2021 | May 1, 2024 |
| Nov 30, 2022 | Nov 30, 2025 |
“Class C / 3rd degree felony” label vs. the default SOL rule
Even if your case involves a Class C / 3rd degree felony, this page is designed to apply the general/default SOL period (since no alternative charge-specific SOL rule is identified in the brief). So the deadline you compute here should reflect the 3-year baseline in MCA § 27-2-102(3), unless the calculator inputs you select correspond to a known exception/tolling scenario.
Key exceptions
SOL deadlines in Montana can change when certain exceptions apply—most commonly through concepts like tolling (pausing or extending the SOL period) or through a different start date than the alleged incident date.
Because this is meant to be practical (not legal advice), here’s how to think about exceptions in a way that supports correct calculator usage:
Common exception themes to watch for
- Tolling or suspension of the SOL clock (pausing the deadline)
- A different triggering/start date (the calculator may use an event other than the offense date)
- Procedural factors that affect how long the clock runs
Operationalize exceptions in DocketMath
When you use DocketMath’s statute of limitations calculator, your inputs control the output. If the calculator includes:
- exception toggles, or
- follow-up questions tied to known timing categories,
choose the option that matches the scenario you’re tracking. If you don’t select an exception and you only enter the offense date (and related start date fields as the tool defines them), the result will follow the default 3-year rule from MCA § 27-2-102(3).
Warning: If an exception applies and you calculate using only the offense date with no exception selection, the deadline you get may be earlier than the real deadline.
Statute citation
Montana Code Annotated § 27-2-102(3) provides the general/default SOL period of 3 years referenced for this baseline criminal SOL calculation.
If you are calculating using the baseline (general/default) rule and not applying an exception category, your computation should anchor to:
- 3 years from the calculator’s chosen start date, pursuant to MCA § 27-2-102(3).
Use the calculator
Use DocketMath to compute the SOL deadline using Montana’s default/general 3-year rule.
- Open the tool: **/tools/statute-of-limitations
- Set:
- Jurisdiction: **Montana (US-MT)
- SOL basis/category: select the calculator’s Montana default/general option (since this page is based on the general/default rule)
- Enter the starting date:
- If you’re tracking the alleged offense date, choose the offense date as the start date when the tool offers that choice.
- Review the output:
- DocketMath should output a deadline date based on 3 years from the chosen start date, consistent with MCA § 27-2-102(3).
Inputs that typically change the result
If your computed deadline doesn’t match expectations, review:
- Starting date selection
- Offense date vs. another event date can materially change the output.
- Exception/tolling option selection
- Selecting a different exception category can extend or alter the deadline compared to the default.
- General/default vs. other categories
- This page assumes general/default only (no charge-specific sub-rule identified), so ensure the calculator isn’t switching categories.
Quick example workflow:
- Alleged offense date: Aug 10, 2021
- Default SOL rule: 3 years (MCA § 27-2-102(3))
- Expected output (baseline): Aug 10, 2024 (unless exception/tolling inputs change the timeline)
Sources and references
Start with the primary authority for Montana and confirm the effective date before relying on any output. If the rule has been amended, update the inputs and rerun the calculation.
