Statute of Limitations for Child Sexual Abuse / Assault in Montana
6 min read
Published March 22, 2026 • By DocketMath Team
Overview
Montana law imposes deadlines—known as statutes of limitations (SOL)—for filing claims in court. For child sexual abuse or assault, many people assume there is a special, longer lookback rule. In Montana, the core starting point can be straightforward: for many time-based claims, Montana applies a general limitations period rather than a claim-specific rule for child sexual abuse/assault.
Based on the available jurisdiction data for Montana, the default limitations period is 3 years under Montana Code Annotated § 27-2-102(3). No separate, claim-type-specific sub-rule for child sexual abuse/assault was identified here, so the best way to understand Montana’s baseline is to treat it as a general rule unless a separate exception clearly applies.
Note: This overview is written to help you understand the framework and deadlines. It’s not legal advice, and outcomes can depend on the specific facts, the type of claim filed, and how Montana courts apply the rules.
If you’re using DocketMath’s statute-of-limitations calculator, the main practical question becomes: when does the clock start, and are any exceptions extending or changing the deadline? The sections below walk through those inputs and how the output changes.
Limitation period
Default rule: 3 years
For Montana, the general SOL period provided in the jurisdiction data is:
- 3 years
- General statute: **Montana Code Annotated § 27-2-102(3)
In practical terms, “3 years” means the case generally must be filed within 3 years of the legally relevant start date (often tied to accrual or discovery concepts, depending on the claim type and Montana’s application).
What you should model in a calculator
To use DocketMath effectively for a Montana child sexual abuse/assault matter, you’ll typically want to model these key facts:
- Date of the event(s) (or the date of the last event, if there were multiple)
- Potential start date (often based on accrual rules or when the legal claim is considered to have begun)
- Whether an exception could apply (for example, rules affecting minors or delayed discovery concepts, if applicable)
Because this is a “reference-page” style explanation, we’re treating § 27-2-102(3) as the default period for deadline calculations in the absence of a found claim-specific rule. That means the output from DocketMath should start from a 3-year baseline unless your inputs (or an exception you qualify for) shift the start date or extend the deadline.
Output logic (how the deadline changes)
When you run the DocketMath calculator, the deadline generally moves based on:
- Later start date → later filing deadline
- Earlier start date → earlier filing deadline
- Exception/adjustment inputs (if available) → adjusted deadline
To get a useful result, enter the date(s) you want the calculator to treat as the accrual/trigger point and then compare the computed “last day to file” to your target filing date.
Key exceptions
Because the jurisdiction data provided here identifies a general/default SOL and notes that no claim-type-specific sub-rule was found, the most reliable “exception” approach in this page is to focus on exceptions that alter the start date or extend time rather than assuming there’s an automatic child-sexual-abuse-specific SOL.
In Montana SOL analysis, exceptions are often procedural and fact-dependent. Common exception categories you may need to check (depending on the claim and facts) include:
- Rules that affect minors (for example, time may start running later when the claimant reaches a certain age or when a disability is removed)
- Delayed discovery concepts (where a claim might be considered to accrue when it is reasonably discoverable)
- Tolling (pauses in the clock due to specific legal circumstances)
How to use “exception thinking” in DocketMath
Even without a claim-type-specific rule identified here, you can still use exceptions to refine the timeline:
- If you believe the clock should start later than the event date, adjust the start/trigger input accordingly.
- If your fact pattern suggests tolling or delayed accrual, use the calculator’s exception/trigger inputs (if present) to reflect that later start.
- If the calculator only supports one baseline, run multiple scenarios:
- Scenario A: use the earliest plausible trigger date
- Scenario B: use the later plausible trigger date
- Scenario C: apply any available exception/tolling adjustment
Warning: Exception application can materially change the filing deadline. Two cases with similar facts can still differ if the trigger date or the tolling basis is treated differently.
Statute citation
The general/default Montana statute of limitations period identified for the baseline timeframe is:
- Montana Code Annotated § 27-2-102(3) — 3-year general limitations period
This page treats § 27-2-102(3) as the baseline for deadline calculations. It does not assume a separate child sexual abuse/assault SOL rule because none was found in the provided jurisdiction data.
Use the calculator
DocketMath’s statute-of-limitations calculator helps you translate the rule into a concrete deadline. Start at:

Suggested inputs to model (Montana, default baseline)
Use the calculator with inputs that reflect your case timeline:
- Jurisdiction: US-MT
- Baseline period: 3 years (from § 27-2-102(3))
- Trigger/start date: the date you believe the clock begins running (often aligned with accrual or discovery rules)
How the results typically behave
Here’s a simple way to sanity-check what you’ll see:
| Input change you make | What usually happens to the deadline |
|---|---|
| Trigger/start date moves later | Filing deadline moves later by roughly the same number of days/years |
| Trigger/start date moves earlier | Filing deadline moves earlier |
| Exception/adjustment is applied (if supported) | Deadline often extends to reflect the adjusted start point |
If you’re working from a set of dates (multiple incidents, reporting delays, or a late awareness event), it can help to run a small set of scenarios and compare them.
Practical checklist before you hit “calculate”
Note: If you’re unsure which date should control the SOL trigger, treat DocketMath output as a range-builder (earliest plausible deadline vs. later plausible deadline) rather than a single definitive date.
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.
