Statute of Limitations for Class C / Petty Misdemeanor in Wyoming

5 min read

Published March 22, 2026 • By DocketMath Team

Overview

Wyoming’s statute of limitations (SOL) sets the maximum amount of time the state has to file criminal charges after an alleged offense. For certain lower-level criminal matters—commonly framed as Class C misdemeanors or petty misdemeanor–type charges in everyday discussions—the SOL is often measured in years, not months.

For DocketMath users, the practical goal is simple: determine the end date by counting forward from a relevant trigger date (commonly the date of the alleged offense) using the correct Wyoming SOL provision.

Note: This page focuses on the SOL timeframe for Wyoming offenses covered by Wyo. Stat. § 1-3-105(a)(iv)(C). It’s written for reference and workflow planning, not legal advice.

Limitation period

The default rule for this offense category

Wyoming provides a 4-year SOL for the type of misdemeanor covered by:

  • **Wyo. Stat. § 1-3-105(a)(iv)(C)

In DocketMath terms, that means your calculation should generally produce an expiration date that is:

  • 4 years after the applicable start date (most often the offense date, unless another statute or fact pattern changes the trigger)

What “4 years” means for your timeline

When you’re building a case timeline (or drafting a motion checklist), treat the 4-year window as a hard boundary for filing unless an exception applies.

A common way practitioners think about this is:

  • Day 0 = the trigger date you input (e.g., the alleged offense date)
  • End of window = “Day 0 + 4 years”
  • If the state files after the end of the window, the filing is generally outside the SOL—though actual outcomes still depend on what the charging documents allege and whether any tolling/exception issues arise.

How to use the calculator inputs effectively (and avoid miscounts)

Before you press calculate, confirm you’re using the right start date. If you’re unsure, you can usually sanity-check by asking:

  • Is the alleged offense tied to a single date or an ongoing course of conduct?
  • Are there multiple alleged acts with different dates?
  • Do the facts reference an event that could shift the trigger from the offense date?

Even with a 4-year SOL, the difference between a January 15 trigger and a March 20 trigger can change the expiration date by a meaningful amount.

Key exceptions

Wyoming’s SOL scheme includes statutory exceptions that can change the analysis from “just add 4 years.”

Exception framework in Wyoming’s SOL statute

The DocketMath statute-of-limitations calculator is built around Wyoming’s specific structure, which includes multiple references that all point to 4 years under different sub-parts or labeled exceptions.

For this Wyoming topic, the provided SOL dataset flags the following SOL-related entries as 4 years with their own exception labels:

  • Wyo. Stat. § 1-3-105(a)(iv)(C) — 4 years — exception M1
  • Wyo. Stat. § 1-3-105 — 4 years — exception M3
  • Wyo. Stat. § 6-2-101 — 4 years — exception N1
  • (null) — 4 years — exception P1

How these exceptions affect the output

In practice, exceptions can affect results in two main ways:

  1. The applicable SOL provision changes
    Instead of using one 4-year subsection, you may need to apply a different labeled portion that still happens to be 4 years—but could differ for other offense categories or related offenses.

  2. The start date or counting method changes
    Some provisions can alter when the clock begins. If an exception changes the trigger, the “4 years” still applies, but the expiration date shifts.

Warning: Don’t rely on the “4-year” number alone. Even when the SOL duration matches, the correct statutory subsection and any exception logic can change the computed end date.

Practical checklist for spotting exceptions

Use this quick checklist when you’re validating your DocketMath inputs:

If any of those checks fail, your computed SOL expiration may be off—even if the solver still uses “4 years.”

Statute citation

The governing citation for the SOL period used by DocketMath for this category is:

  • Wyo. Stat. § 1-3-105(a)(iv)(C)4 years

This is the core statute line identified for the Class C / petty misdemeanor timeframe in Wyoming’s SOL structure.

Use the calculator

DocketMath’s statute-of-limitations calculator helps you translate the Wyoming SOL rule into a date you can use in your timeline.

Primary CTA: /tools/statute-of-limitations

What you input

Typically, you’ll provide:

  • Jurisdiction: Wyoming (US-WY)
  • Trigger date: the date you want the SOL clock to start (commonly the alleged offense date)
  • Offense category: select the option that corresponds to the misdemeanor type covered by **Wyo. Stat. § 1-3-105(a)(iv)(C)

What the calculator outputs

After you calculate, DocketMath returns:

  • SOL end date (trigger date + the applicable SOL period)
  • An explanation tying the result to the 4-year rule in Wyo. Stat. § 1-3-105(a)(iv)(C) and its mapped exception logic.

How outputs change when inputs change

Use these “what-if” scenarios to confirm the tool is working as expected:

  • If you move the trigger date forward by 30 days, the SOL end date should also move forward by about 30 days (because the SOL duration is measured in years).
  • If you switch the selected offense category to one mapped under a different exception bucket, DocketMath may use a different statute subsection or counting logic, shifting the end date even if the duration remains 4 years.

For a fast workflow, run two calculations if your timeline includes multiple alleged act dates—then compare the resulting SOL end dates against your filing/charging date.
