Statute of Limitations for False Arrest / False Imprisonment in Washington
5 min read
Published March 22, 2026 • By DocketMath Team
Overview
In Washington, claims described as false arrest or false imprisonment are commonly treated under Washington’s general civil statute of limitations for personal injury–type harms. Under the framework in RCW 9A.04.080, Washington generally imposes a 5-year deadline to file suit for these kinds of claims.
Because you asked specifically for false arrest/false imprisonment: DocketMath uses the general/default limitations rule where a claim-type-specific sub-rule was not found. That means you should plan around the 5-year general SOL rather than looking for a shorter or special deadline that applies only to false arrest/false imprisonment.
Note: This page covers Washington’s limitations timing at a high level. It’s not legal advice, and timing can be affected by case-specific facts (for example, when a plaintiff “discovered” relevant facts or whether tolling applies).
Limitation period
Default (general) limitations period: 5 years
Washington’s general statute of limitations period is 5 years for the types of claims captured by RCW 9A.04.080. For a false arrest/false imprisonment scenario, that typically means your lawsuit should be filed within 5 years of the relevant starting point recognized by Washington law (often tied to the accrual date—when the claim could first be brought).
How the timing usually flows (practical timeline)
While every case has its own accrual details, a practical way to think about the deadline is:
- Start: the date the facts giving rise to the claim occurred (commonly the date of the arrest/detention or when the claim accrued)
- Deadline: 5 years from that start date
Here’s a simple example to illustrate the math:
| Alleged incident date | General SOL deadline (5 years) |
|---|---|
| March 1, 2021 | March 1, 2026 |
| November 15, 2022 | November 15, 2027 |
Inputs that change the output
DocketMath’s statute-of-limitations calculator is designed to take the core information that drives the deadline:
- Incident / accrual date (the date you’re using as the clock start)
- Jurisdiction (Washington / US-WA)
- SOL rule (the default general rule found in RCW 9A.04.080)
If the incident date changes by even days, your computed deadline changes accordingly because you’re adding 5 years to the start date under the general rule.
Checklist before you run the calculator

Key exceptions
Washington law includes doctrines and statutory rules that can affect deadlines, even when the general SOL period is 5 years. DocketMath’s calculator will generally apply the base SOL period; it may not automatically incorporate every tolling or exception scenario.
Common categories of exceptions to consider include:
- Tolling (pauses or delays)
Some legal circumstances can pause the limitations clock, meaning the filing deadline can move later than the straightforward “start date + 5 years” calculation. - Accrual nuances (when the clock starts)
The limitations period depends on when the claim accrues. In many false arrest/false imprisonment fact patterns, accrual is often tied closely to the detention/arrest event. Still, the specific accrual date can vary with the facts. - Equitable considerations
Courts sometimes address fairness concerns through equitable doctrines, depending on the situation and statutory structure.
Warning: Do not assume the “5 years from the incident date” rule always controls. If you believe tolling, delayed accrual, or another exception may apply, the timeline could shift—sometimes materially.
What DocketMath will do (and what it won’t)
- DocketMath will help you compute the baseline deadline using the general/default rule tied to RCW 9A.04.080 (5 years).
- You should still treat the computed date as a starting point, then verify whether the case involves an accrual change or a tolling argument supported by Washington law and the specific facts.
If you want a fast workflow, run the calculator using the incident/accrual date first, then separately review whether any exception category fits your situation.
Statute citation
Washington’s general statute of limitations for these claims is governed by:
- RCW 9A.04.080 — 5-year general statute of limitations
DocketMath applies this as the general/default period because a claim-type-specific sub-rule for false arrest/false imprisonment was not found for this page’s scope. In other words: the 5-year default rule is the rule you should plan around unless your situation supports a different accrual date or a recognized tolling/exception doctrine.
Use the calculator
Use DocketMath’s statute-of-limitations calculator to compute the deadline for Washington (US-WA): /tools/statute-of-limitations.
Step-by-step
- Open: /tools/statute-of-limitations
- Select or confirm:
- Jurisdiction: Washington (US-WA)
- Rule: the general/default 5-year SOL under RCW 9A.04.080
- Enter the incident/accrual date you’re using as the clock start.
- Review the computed deadline date.
How output changes with your inputs
- If you enter a later incident/accrual date, your output deadline becomes later by the same time shift.
- If you use a different accrual date (for example, if you believe the claim accrued on a date other than the arrest/detention date), the computed deadline will also move.
Note: The calculator helps you compute the baseline deadline. If you’re relying on an accrual/tolling position, you may want to run multiple scenarios (using different candidate start dates) to see how sensitive the deadline is.
Practical filing strategy
Once DocketMath generates a deadline, consider aiming to file earlier than the computed date. Court processing timelines, service of process, and document preparation can create real-world pressure close to the deadline.

Start with the primary authority for Washington and confirm the effective date before relying on any output. If the rule has been amended, update the inputs and rerun the calculation.
