Worked example: Alimony Child Support in Hawaii

Example inputs

Below is a worked example showing how you can use DocketMath’s alimony-child-support calculator for Hawaii (US-HI). This example focuses on the general statute of limitations (SOL) framework that the tool uses to translate a payment dispute into a time window that you can reference in a filing workflow.

You can run the same type of analysis here: Primary CTA: /tools/alimony-child-support

Scenario (facts you would enter)

Use these as the “example inputs” for the calculator:

• Jurisdiction: Hawaii (US-HI)
• Payor’s payment type (context): combined alimony + child support calculation context
• Alleged underpayment period start date: January 1, 2018
• Alleged underpayment period end date: December 31, 2021
• Date the issue is raised (filing/claim trigger date): March 15, 2024
• Frequency assumption for calculation: monthly
• Amount basis (for demonstration):

  • Child support “target” amount: $1,200 / month
  • Alimony “target” amount: $400 / month
• Actual paid (for demonstration):

  • Child support actually paid: $1,050 / month
  • Alimony actually paid: $400 / month

Example run

Now run the example through DocketMath (alimony-child-support) using the inputs above. Since the tool is designed to evaluate arrears within the SOL window, the key outputs typically break into:

1. Months included by SOL window
2. Monthly shortfall
3. Total shortfall inside the window
4. Notes about excluded months (outside the SOL window)

Step 1: Identify the Hawaii SOL rule the tool is applying

For Hawaii, the jurisdiction configuration uses a general/default SOL period:

• General SOL Period: 5 years
• General Statute: Hawaii Revised Statutes (HRS) § 701-108(2)(d)
• Source: https://codes.findlaw.com/hi/division-5-crimes-and-criminal-proceedings/hi-rev-st-sect-701-108/?utm_source=openai

Important clarification: No claim-type-specific sub-rule was found in the provided jurisdiction data. That means the calculator treats the SOL window as the general/default 5-year period, rather than narrowing it based on a specific support-claim category.

Step 2: Convert the trigger date into a “lookback” time window

With a trigger date of March 15, 2024 and a 5-year general SOL:

• Lookback window begins: March 15, 2019
• Practical meaning: payments before March 15, 2019 are outside the general/default SOL window used by the calculator.

So, in this worked example, the calculator’s “covered period” will generally include months that fall on/after the boundary and exclude months in 2018 and early 2019 (depending on the tool’s month allocation convention).

Step 3: Define which months are counted (month-allocation convention)

Your alleged period runs:

• January 2018 → December 2021

Because the SOL boundary is mid-March 2019, early 2019 months may be excluded or partially allocated.

To keep this example concrete, we’ll use this counting approach:

• 2018: excluded (fully outside the 5-year window)
• Jan–Mar 2019: excluded or partially excluded depending on the tool’s day-to-month handling
• Apr 2019–Dec 2019: included
• All 2020: included
• All 2021 (through Dec 2021): included

Step 4: Compute the monthly shortfall inside the window

From the demonstration inputs:

Child support

• Target: $1,200 / month
• Paid: $1,050 / month
• Shortfall: $1,200 − $1,050 = $150 / month

Alimony

• Target: $400 / month
• Paid: $400 / month
• Shortfall: $400 − $400 = $0 / month

Total shortfall per month (combined):

• $150 + $0 = $150 / month

Step 5: Multiply by the included month count

Using the example month counts implied by the included months:

• Apr–Dec 2019: 9 months
• 2020: 12 months
• 2021: 12 months
• Total included months: 33 months

Total shortfall inside the SOL window:

• $150 × 33 = $4,950

Step 6: Interpret how the tool’s “covered time” changes the output

The core jurisdiction-aware effect is this:

• The same alleged underpayment (2018–2021) does not automatically produce a full-period arrears total.
• Instead, DocketMath restricts arrears to the months within the general/default 5-year SOL window based on HRS § 701-108(2)(d).
• As a result, months outside the boundary (e.g., most of 2018 and early 2019) do not contribute to the totals shown in the SOL-bounded output.

Practical “what to look for” in the results panel

When you review the results in DocketMath, look for elements like:

• Covered period (months/days within the SOL window)
• A calculation summary showing arrears inside the window for:

  • child support within the window
  • alimony within the window
  • combined shortfall within the window
• Explanatory text confirming that the SOL period used is the general/default 5-year rule (consistent with the lack of a claim-type-specific sub-rule in the jurisdiction data)

Practical checklist for your own run

• Confirm jurisdiction is Hawaii (US-HI)
• Enter the alleged underpayment start and end dates
• Enter the trigger date (date the issue is raised)
• Input monthly target amounts and monthly actual amounts
• Verify that the SOL basis shown by the tool is the general/default 5-year period (because no claim-type-specific sub-rule was found)

Sensitivity check

This example is designed to show what changes the result most: (1) the SOL boundary (trigger date) and (2) the monthly shortfall (actual vs. target payments).

1) Change the trigger date by ~6 weeks

• Original trigger date: March 15, 2024
• New trigger date: May 1, 2024

With a 5-year window, the lookback start shifts from about March 15, 2019 to about May 1, 2019.

Expected impact in this example:

• You may exclude 1 additional month near the boundary.
• With a monthly combined shortfall of $150, that implies approximately −$150 from the SOL-bounded total.

So the total might move from:

• $4,950 → about $4,800 (directionally; exact value depends on how the calculator allocates partial months around boundary dates).

2) Change only actual child support paid

Keep dates fixed, but update:

• Child support actually paid: $1,100 / month (instead of $1,050)
• New child support shortfall: $1,200 − $1,100 = $100 / month
• Included months: still 33 months (SOL window unchanged)

Recompute total inside SOL window:

• $100 × 33 = $3,300

Expected impact:

• Total decreases by $1,650, which matches the reduction in monthly shortfall ($150 − $100 = $50) times 33 months.

3) Introduce an alimony underpayment

Now assume alimony was also short:

• Alimony actually paid: $350 / month (instead of $400)
• Alimony shortfall: $400 − $350 = $50 / month
• Monthly combined shortfall becomes: $150 (child) + $50 (alimony) = $200 / month
• Included months: still 33 months

Total inside SOL window:

• $200 × 33 = $6,600

Expected impact:

• Total increases by $1,650 relative to the original case, because you add $50/month across 33 included months.

Bottom-line sensitivity takeaway

• The SOL window mainly controls how many months are counted.
• The payments control the monthly shortfall, which scales the total.
• Together, these determine the SOL-bounded arrears figure DocketMath reports.
