Overview

In Montana, claims involving interference with someone else’s property—often framed in practice as trespass to chattels or conversion—run into a common procedural cutoff: the statute of limitations (SOL). Once that time period expires, a claim may be barred even if the underlying facts are persuasive.

For Montana, the SOL rules you’ll most often rely on start with a general/default limitation period. Based on the Montana Code rule cited below, there is no claim-type-specific sub-rule provided here for trespass to chattels or conversion. Instead, the analysis applies the general rule:

Default SOL period: 3 years
Governing statute: **Montana Code Annotated (MCA) § 27-2-102(3)

Because SOL questions can turn on case-specific details (especially around when the injury “accrued”), this page is designed to help you model deadlines using DocketMath rather than guess at legal outcomes.

Note: This overview uses Montana’s general/default SOL rule because no specific trespass-to-chattels or conversion sub-rule was identified in the provided jurisdiction data.

Limitation period

The general rule: 3 years from accrual

Montana’s default statute of limitations for covered civil actions is three years, under MCA § 27-2-102(3). In practical terms, that generally means the clock starts when the claim accrues—commonly described as the time when the alleged wrongful conduct causes a legally actionable harm.

Because “accrual” can vary with the facts (for example, when a party discovers the interference or when the property is taken or retained), you should treat the SOL start date as an input you may need to confirm based on your record.

How to model the deadline with DocketMath

Use DocketMath’s statute-of-limitations calculator to translate the rule into a calendar deadline.

Typical workflow:

Identify the event date (e.g., the date of the alleged taking, retention, or wrongful interference).
Decide the accrual date you intend to test (often the same as the event date, but not always).
Enter the date into DocketMath.
Review the resulting “latest filing date” output.

Inputs and how outputs change

Below are the inputs you’ll typically control—and how changing them changes the output.

Input you choose	What it represents	Effect on deadline
Accrual date	When the claim is considered to have started running	Later accrual date → later SOL deadline
Case type set to Montana default	Applies MCA § 27-2-102(3)	Ensures the calculator uses the 3-year period
Any provided tolling/exception toggles	Extra time added or start date adjusted	Extends or shifts the deadline (only if applicable)

If you’re unsure about accrual, run two scenarios:

Scenario A: accrual = event date
Scenario B: accrual = discovery/known date (if your facts support that framing)

Then compare the “latest filing date” for each scenario. This is not a legal conclusion—just a deadline planning tool.

Key exceptions

Montana SOL analysis often turns on whether an exception changes either:

the length of the period, or
the start date (accrual), or
both.

This page focuses on the general/default 3-year rule because no claim-type-specific sub-rule was identified in the provided data. Still, you should be aware of the categories of exceptions courts commonly consider in Montana civil SOL questions, such as:

Tolling due to legal disability or incapacity
Defenses related to fraudulent concealment or misleading conduct
Statutory tolling triggers tied to particular circumstances

Warning: Exceptions can materially shift deadlines. A “3 years” calculation is a baseline, not a guarantee that the deadline is fixed.

Practical checklist for exception screening

Use this short list to decide what additional fact review you may need before relying on a date:

If you answer “yes” to any of these, your SOL timeline may require an updated model rather than a straight subtraction of 3 years.

Statute citation

Montana’s general/default statute of limitations for covered civil actions is:

Montana Code Annotated § 27-2-102(3) — 3 years

For this topic (trespass to chattels / conversion in Montana), the provided jurisdiction data indicates no claim-type-specific sub-rule was found. Accordingly, the 3-year general rule is the baseline limitation period discussed here.

Use the calculator

To calculate a Montana SOL deadline for this general/default 3-year rule, go to DocketMath’s calculator:

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

When you use DocketMath, keep these best practices in mind:

Choose Montana as the jurisdiction (US-MT).
Select the statute-of-limitations pathway that applies the default 3-year period.
Enter your accrual date (not just the rough timeframe).
If DocketMath provides exception/tolling inputs relevant to your scenario, toggle them only when you have supporting facts.

What you should expect from the output

DocketMath will convert the rule into a specific time boundary—typically a latest filing date—based on the inputs you provide. If you change the accrual date by even a few weeks, the computed deadline will shift accordingly (because the SOL period is counted from the start date).

Pitfall: Using the “incident date” when the claim may have accrued later (or earlier) can produce a misleading deadline. If your records include a clear discovery or awareness date, test both scenarios rather than assuming.

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.
