Statute of Limitations for Discovery Rule in Arizona

Overview

Arizona’s general criminal statute of limitations is 2 years under A.R.S. § 13-107(A), and that is the default period to use when no more specific rule applies. For a discovery-rule analysis, the key question is when the issue was discovered, or reasonably should have been discovered, because that date can control when the clock starts in some situations.

This page is a practical reference for calculating the Arizona limitations window in a discovery-rule context. It is not legal advice, but it can help you understand the default period, the start date to test, and the inputs that matter most when using the DocketMath statute-of-limitations tool.

Note: The Arizona jurisdiction data provided here identifies a 2-year general period and does not include a claim-type-specific sub-rule. Use the general/default period unless a separate Arizona statute clearly applies.

Limitation period

Arizona’s general limitations period is 2 years. That means the baseline deadline is measured as 2 years from the controlling start date.

For discovery-rule questions, the start date is often the point at which the issue was:

  • actually discovered, or
  • reasonably should have been discovered through ordinary diligence

That distinction matters because the filing deadline can change depending on which date applies.

How the calculation changes

The output changes based on three practical inputs:

InputWhat it affectsExample impact
Discovery dateStarts the clock in discovery-rule analysisA later discovery date can extend the deadline
Filing dateDetermines whether the matter is timelyFiling before the deadline = within limitations
Applicable statuteSets the baseline periodArizona default here is 2 years

Simple timeline example

If a claim is treated as accruing on March 1, 2024, the ordinary 2-year period would end on March 1, 2026. If discovery is later recognized on July 15, 2024, the calculated deadline may shift accordingly, depending on the governing statute and facts.

In practice, the discovery rule is not an automatic extension. It changes the start point only when the law treats discovery as the operative trigger.

Key exceptions

Arizona does not use one universal rule for every deadline. The 2-year default in A.R.S. § 13-107(A) is the general period in the jurisdiction data provided, and no claim-type-specific sub-rule was identified in that data set.

Here are the most important exception categories to watch for when evaluating whether the default period applies:

  • Specific statute controls over the general rule.
    • If another Arizona statute creates a different limitations period, that specific statute governs.
  • Discovery-based accrual can change the start date.
    • The claim may not begin on the date of the underlying conduct if the statute or doctrine ties accrual to discovery.
  • Tolling can pause or extend the deadline.
    • Certain legal disabilities or other statutory events can affect the running of the period.
  • Different case types can have different limitation periods.
    • Criminal, civil, and administrative deadlines are not interchangeable.

Practical checklist for exception screening

Pitfall: Using the 2-year default without checking for a more specific Arizona statute can produce the wrong deadline, especially when a discovery rule or special accrual rule applies.

Statute citation

The jurisdiction data you supplied points to A.R.S. § 13-107(A) as the general Arizona statute and 2 years as the default limitations period.

What the citation means in practice

When you are evaluating a deadline in Arizona, the statute citation is the anchor for the calculation. The citation tells you:

  1. which statute controls,
  2. what period applies, and
  3. whether you need to look for a more specific rule.

For reference workflows, that means the citation is not just a label. It determines the calendar math behind the deadline.

If you need a fast way to test a start date against Arizona’s period, you can use the DocketMath statute of limitations calculator to compare dates and see the deadline window.

Use the calculator

DocketMath helps you turn the statute into a deadline by applying the Arizona period to your selected dates. For discovery-rule issues, the calculator is most useful when you are comparing:

  • discovery date,
  • filing date,
  • and any alternative accrual date you want to test

What to enter

Use the calculator with the dates that matter to the accrual analysis:

  1. Start date
    • Enter the discovery date if the discovery rule controls.
    • If you are testing a different theory, enter the date you believe the clock began.
  2. Filing date
    • Use the date the complaint, claim, or filing was submitted.
  3. Jurisdiction
    • Select Arizona.
  4. Period
    • Apply the 2-year default from A.R.S. § 13-107(A) unless a specific statute changes it.

What the output tells you

The calculator shows whether the filing date falls:

  • before the deadline,
  • on the deadline, or
  • after the deadline

That result gives you a fast way to spot deadline risk. It also helps you compare alternate start dates. For example, if a discovery date moves by 90 days, the deadline usually moves by the same amount when the same limitations period applies.

Best uses for reference work

  • confirm a deadline before drafting
  • compare two possible accrual dates
  • stress-test a filing date against the 2-year period
  • document the limitation window in a case note or intake summary

For a fast calculation, open the DocketMath statute of limitations calculator and enter the dates you want to test.

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