Statute of Limitations for Class C / 3rd Degree Felony in New Hampshire
6 min read
Published March 22, 2026 • By DocketMath Team
Overview
In New Hampshire, the statute of limitations (SOL) sets the maximum time the state can bring a criminal case after the alleged offense. For a Class C / 3rd Degree felony, the relevant starting point is the general criminal limitations period in RSA 508:4.
DocketMath’s statute-of-limitations calculator is designed to help you estimate deadlines from key dates (like the alleged offense date and a selected calculation basis). Because SOL analysis can depend on procedural posture and event timing, this article focuses on the baseline rule and the most common categories of adjustments—without providing legal advice.
Note: Your deadline calculation can change if there are tolling events, arrests, or other procedural actions that affect when the SOL is counted. Use the calculator as a planning aid, not a substitute for case-specific review.
Limitation period
Default SOL for Class C / 3rd Degree felony (NH)
New Hampshire’s general rule provides a 3-year SOL for covered offenses under RSA 508:4.
- General SOL period: 3 years
- General statute: RSA 508:4
- Claim-type-specific sub-rule: No claim-type-specific sub-rule was found for this class in the information provided—so the general/default period applies for this purpose.
What “3 years” means in practice
The SOL period runs from a governing “start date” tied to the offense timing and the facts that trigger prosecution timing. In many SOL tools, the start date is operationalized as:
- Alleged offense date (most common input), or
- The date of discovery / last element timing if a specific statutory or procedural doctrine applies.
Because this guide specifies the general/default period and does not identify a different class-specific trigger, the calculator typically assumes the offense date as the SOL start for a baseline estimate.
How DocketMath’s calculator output changes with inputs
When you use DocketMath (or a similar SOL calculator), the output you get will depend on at least these variables:
- Offense date (start date):
- Moves the deadline forward or backward by the number of days between the dates.
- Selected calculation method / basis:
- Some tools calculate from offense date to “last permissible filing” date.
- Whether you apply tolling adjustments:
- If you select tolling concepts (when available), the end date usually extends.
In other words:
- Change the offense date → the SOL expiration date shifts accordingly.
- Apply a tolling period → the SOL expiration date extends by that duration.
Practical checklist before calculating
To reduce errors, gather the following dates and details before running the calculator:
Key exceptions
Even when the baseline SOL is 3 years under RSA 508:4, SOL deadlines can shift due to exceptions, tolling, or procedural events. The exact mechanics can be fact-dependent, so think of the items below as “what to look for” rather than a guarantee that any single exception applies.
Common categories that can affect SOL timing
Here are categories that often matter in criminal SOL calculations in New Hampshire systems:
- Tolling based on the defendant’s status or conduct
- Examples in general SOL practice include periods where the defendant is not amenable to prosecution or where legal proceedings prevent counting time.
- Events in the prosecution timeline
- Some actions can interrupt or reset counting depending on the statutory framework.
- Continuing conduct
- If conduct spans multiple dates, the “start” and “end” of the conduct can matter.
- Amendments or recharging
- If a case is filed and later modified, the timing rules may not be a simple one-to-one comparison.
Warning about “general rule” assumptions
Warning: A 3-year baseline under RSA 508:4 can be wrong for a particular situation if there is a tolling event or a different statutory mechanism affecting when time starts or stops running.
How to handle exceptions safely in your workflow
Instead of trying to guess which exception applies, use a structured approach:
- Run the baseline 3-year estimate (using the offense date).
- Compare the baseline deadline to the charging or filing date.
- Review the record for SOL-relevant events:
- Was there a period where prosecution couldn’t proceed?
- Did the defendant’s location or legal status create an interruption?
- Were there multiple dates of relevant conduct?
- Recalculate with any tolling periods you can justify from the case timeline.
If you’re building an internal workflow (e.g., for intake, case tracking, or analytics), document both:
- Baseline SOL date (from the calculator), and
- Assumptions applied (e.g., “no tolling selected”).
Statute citation
New Hampshire general statute of limitations (general/default period):
- RSA 508:4 — provides the 3-year SOL baseline referenced for the covered category discussed here.
Baseline period used in this guide:
- 3 years under RSA 508:4 (general/default; no class-specific sub-rule identified in the provided jurisdiction data)

Typical calculator inputs (and what to expect)
Depending on the calculator’s interface, you’ll usually provide:
- Offense date (start date)
- Output: baseline SOL expiration date = offense date + 3 years
- Jurisdiction selection: New Hampshire (US-NH)
- Output: applies RSA 508:4 general period
- Optional tolling/adjustments (if the tool supports them)
- Output: recalculates expiration date after adding excluded/tolling time
Output interpretation
After you run the calculation, compare results like this:
- If charging/filing date ≤ SOL expiration date → baseline suggests “within the SOL window.”
- If charging/filing date > SOL expiration date → baseline suggests “beyond the SOL window.”
- If tolling/exception inputs are used → treat the result as an adjusted estimate, and keep the assumptions in your notes.
Note: This guide uses the general/default 3-year period because no class-specific sub-rule was identified in the provided jurisdiction data. If your case involves specific procedural or tolling events, update the calculator inputs accordingly.
Quick example workflow (no legal conclusion)
- Step 1: Enter offense date.
- Step 2: Confirm New Hampshire is selected.
- Step 3: Record the baseline expiration date (RSA 508:4 general 3-year rule).
- Step 4: If your timeline suggests potential tolling, add it as supported by case facts.
- Step 5: Save both baseline and adjusted outputs in your case tracking notes.
