Statute of Limitations for Murder / First-Degree Murder in Washington

6 min read

Published March 22, 2026 • By DocketMath Team

Overview

In Washington, the statute of limitations (SOL) for murder is governed by RCW 9A.04.080. Practically speaking, the clock question comes up most often when a case is delayed—whether due to investigative complexity, evolving evidence, witness availability, or whether charges are brought later rather than sooner.

For first-degree murder specifically, RCW 9A.04.080 is the starting point for calculating the filing deadline. Under the statute’s structure, most covered offenses fall under a general limitations period, with certain exceptions that shorten the timeline for particular categories of cases.

DocketMath helps you model the SOL timeline so you can see how “date of offense” and “date charges are filed” affect whether the case falls within the limitations window.

Note: This page explains how Washington’s SOL rule is structured and how to compute the limitations window for planning and analysis—not legal advice. Charging decisions and case-specific events can affect the outcome.

Limitation period

General rule: 5 years

Washington’s general SOL under RCW 9A.04.080 is 5 years for covered felonies subject to that section. Using the data for this calculator topic:

  • SOL Period (general): 5 years
  • Statute basis: RCW 9A.04.080

How to think about it (practical workflow):

  1. Identify the date of the offense (or the date the offense is treated as occurring for SOL purposes in the specific charging theory).
  2. Count 5 years forward from that date.
  3. Compare the forward deadline to the date charges are filed (or another procedural date your analysis is using in DocketMath).

If the charging date is after the 5-year mark, the prosecution may be time-barred under the general rule—unless an exception applies.

Shorter timelines via exceptions

The same statute contains exceptions that reduce the period in certain situations. Based on the jurisdiction data provided for this Washington calculator topic, there are two “3 years” exception tracks referenced as:

  • RCW 9A.04.080 — 5 years — exception P1
  • RCW 9A.04.080(1)(j) — 3 years — exception V1
  • null — 3 years — exception V2 (as provided in the jurisdiction data)

In plain terms: most cases start at 5 years, but some categories fall into a 3-year window instead.

Key exceptions

The most common reason SOL outcomes differ from the “headline” 5-year rule is that a case fits an exception clause. For Washington, the data you’re working with points to:

1) Exception tied to RCW 9A.04.080(1)(j): 3 years

  • Reference: **RCW 9A.04.080(1)(j)
  • Limitations period: 3 years
  • Effect: Replaces the general 5-year window with a 3-year deadline for qualifying cases.

What changes in your calculation:

  • Same “date of offense,” but the forward deadline becomes 3 years instead of 5 years.
  • A charge filed between years 3 and 5 could be within the general window but outside the 3-year exception window—so the exception question is decisive.

2) Additional 3-year exception noted in the provided data (V2)

  • Reference in provided data: “null — 3 years — exception V2”
  • Limitations period: 3 years

Because the brief provides the SOL period and the “3 years” label for V2 without a specific textual subsection, you should treat this as a second, distinct exception branch in the context of the DocketMath calculator’s configuration for US-WA. In other words: the calculator may have multiple ways a case can land in a 3-year tier.

Warning: Exceptions often depend on how the charge is framed and which statutory category it falls under. When you input dates into DocketMath, make sure you’re using the correct “offense type / exception selection” so the tool applies the right timeline.

Quick comparison table

Scenario (Washington SOL configuration)Applicable SOL periodWhat the deadline shift means
General murder/first-degree murder SOL bucket5 yearsCharges filed up to 5 years after the offense date may be timely (subject to other factors).
Exception category RCW 9A.04.080(1)(j)3 yearsDeadline moves earlier by 2 years; filings after 3 years are at higher risk of being time-barred.
Second 3-year exception (V2 in provided data)3 yearsAnother path to a shortened period; use the calculator’s exception option to match the intended category.

Statute citation

Washington’s limitations rule for these offenses is found at:

  • RCW 9A.04.080 (Statute of limitations provisions)

Specific to the shortened period identified in the provided jurisdiction data:

  • RCW 9A.04.080(1)(j)3 years (exception V1 in the provided data)

This is the statutory anchor for the DocketMath “statute-of-limitations” calculator topic for US-WA.

Use the calculator

Use DocketMath’s statute-of-limitations tool to model whether a charge date falls inside the applicable SOL window. Start by navigating to:

What to input (and why it matters)

Typically, SOL calculators rely on:

  • Date of offense (the starting point for counting forward)
  • Date charges were filed (or the procedural date you want to test against the deadline)
  • Applicable SOL tier / exception selection (general 5-year vs. 3-year exception)

Because this jurisdiction brief specifies:

  • General: 5 years
  • Exception: 3 years via RCW 9A.04.080(1)(j) and another 3-year exception branch in the configuration

…the critical input is selecting the correct tier.

How outputs change based on inputs

Check your result in three common ways:

  • If you switch from 5 years to 3 years:
    The deadline advances backward by 2 years. A “timely” result under 5 years may become “expired” under 3 years.

  • If the charge date is close to the boundary:
    A difference of weeks or months can flip the outcome.

  • If you input the wrong offense date:
    Every downstream deadline changes. Confirm the offense date you’re using corresponds to the charging theory and timeline you’re analyzing.

Practical checklist before you hit calculate

Once you run DocketMath, the output should clearly show the computed SOL deadline and whether the chosen charge date falls before or after it.

Sources and references

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.
