Step-by-step

This guide walks you through running Alimony + Child Support calculations in DocketMath for Vermont (US‑VT). DocketMath applies jurisdiction-aware rules so you can focus on accurate inputs and a clean output.

Note: This walkthrough is about using the DocketMath calculator. It’s not legal advice, and it can’t replace a Vermont court’s final determination in a specific case.

1) Open the Vermont calculator

  1. Go to /tools/alimony-child-support
  2. Confirm the jurisdiction is set to Vermont (US‑VT).

If your interface shows a jurisdiction selector, set it to US‑VT so the calculator uses Vermont’s guideline framework.

2) Enter the child support income inputs (Vermont guideline model)

Vermont directs courts to determine the total child support obligation using a support guidelines table applied to the parents’ combined available income.

  • Vermont statute basis: 15 V.S.A. § 656
    • The statute requires: “The total child support obligation shall be determined by use of the support guidelines table … applied to the parents' combined available income.

In DocketMath, you’ll typically provide:

  • Parent A available income
  • Parent B available income
  • (If prompted) time-sharing / custody allocation inputs used by the tool to allocate the obligation

How inputs change outputs:

  • When you increase either parent’s available income, the combined available income increases, and the Vermont guideline table generally drives the total child support obligation upward.
  • If the tool includes a time-sharing component, changing it can alter how the total obligation is presented or allocated between periods.

3) Enter the spousal maintenance (alimony) inputs (15 V.S.A. § 752)

Vermont’s spousal maintenance framework is addressed in 15 V.S.A. § 752. In DocketMath, enter the fields the calculator requests for maintenance modeling (commonly things like income and any assumptions the tool asks you to confirm).

In practice, alimony-related results tend to be sensitive to:

  • the parties’ relative incomes,
  • the duration / circumstances assumptions (if the calculator includes them),
  • and the specific factors or inputs DocketMath requires.

How inputs change outputs:

  • If you increase the lower-income spouse’s income (relative to the other spouse), the “need/balance” modeled by the tool may change.
  • If you increase the higher-income spouse’s income, the tool’s modeled capacity may change.

4) Choose the “calculation scope” in DocketMath (what you’re actually running)

Make sure you’re running the combined Alimony + Child Support flow, not just one component.

Some DocketMath screens offer options such as:

  • Child support only
  • Alimony only
  • Combined alimony + child support

For this guide, select the combined option so you can see both outputs in one run.

5) Confirm the default timeframe / period behavior

DocketMath may ask about a duration or period. If results depend on “default period” logic, follow what the tool indicates.

Clear default statement (based on the jurisdiction note you provided):

  • No claim-type-specific sub-rule was found.
  • Therefore, the calculation should use the general/default period approach in the Vermont setup.

Warning: If your case facts involve a distinct modification or special scenario, DocketMath’s default period may not mirror every court handling detail. Use DocketMath outputs as a structured starting point, then verify with case-specific requirements.

6) Run the calculation and review outputs

Click Calculate (or the tool’s equivalent). You’ll typically see:

  • Child support output derived from Vermont’s guideline model under 15 V.S.A. § 656
  • Spousal maintenance (alimony) output modeled under 15 V.S.A. § 752
  • Potential totals or an aggregated summary

When reviewing:

  • Check that your income inputs are in the expected units (for example, monthly vs annual).
  • Look for any echoed values that confirm the tool used combined available income for the guideline calculation.
  • Confirm your alimony-related fields match the assumptions you intend to test.

7) Scenario-test with controlled changes

To validate that the calculator is behaving as expected, change one variable at a time.

Try this simple diagnostic sequence:

  • Increase Parent A available income by a fixed amount (example: +$250/month) and rerun.
  • Then reduce Parent B available income by the same fixed amount and rerun (keeping everything else constant).
  • If time-sharing/custody inputs exist, adjust only that field and rerun—without touching incomes.

What you’re looking for:

  • Child support should respond consistently with Vermont’s combined available income approach under 15 V.S.A. § 656.
  • Alimony should respond in a way that matches the tool’s 15 V.S.A. § 752-based modeling inputs/assumptions.

8) Export or record the results

If DocketMath offers a share link, export/download, or printable summary, save it. Recording:

  • your inputs,
  • the selections/assumptions you made,
  • and the output numbers

makes it much easier to compare scenarios later.

Common pitfalls

Small input mismatches can create big differences in the results. These are the most common issues in Vermont runs of the alimony-child-support calculator:

  • Entering annual income when the tool expects monthly
    • Symptom: outputs look inflated by a factor that seems “too large.”
  • Swapping Parent A and Parent B
    • Symptom: you see an alimony direction or allocation that looks reversed.
  • Inconsistent units across fields
    • Example: income fields in one unit, another factor in a different unit.
  • Assuming claim-type-specific periods apply
    • Your jurisdiction note indicates no claim-type-specific sub-rule found, so rely on the general/default period behavior built into the Vermont setup.
  • Forgetting the combined-income logic for child support
    • Vermont’s statute focuses on the parents’ combined available income to determine the total child support obligation under 15 V.S.A. § 656.
  • Over-editing multiple variables at once
    • Diagnostic problem: you won’t know which input caused the change.
  • Treating calculator outputs as final determinations
    • DocketMath can’t capture every evidence issue, procedural rule, or case-specific fact a court may apply.

Pitfall: If the child support output doesn’t move when you change one parent’s income, confirm that the calculator is actually using that field as available income (and not a different label such as gross income).

Try it

Here’s a quick way to validate the Vermont run in DocketMath using the jurisdiction rules:

  1. Start with a baseline scenario:
    • Enter Parent A available income
    • Enter Parent B available income
    • Enter your alimony-related fields required by the calculator
  2. Run the calculation.
  3. Do a single-change test:
    • Increase Parent A available income by $250/month
    • Rerun and observe:
      • whether child support increases in a way consistent with Vermont’s guideline structure based on combined available income under 15 V.S.A. § 656
      • whether alimony shifts under 15 V.S.A. § 752 modeling assumptions

To keep your work organized, create 2–3 scenarios (for example: lower, baseline, higher income balance) and compare the deltas.
