Step-by-step
Below is a practical way to run Alimony + Child Support using DocketMath for South Dakota (US-SD). This walkthrough is jurisdiction-aware and aligns with South Dakota’s governing statutes for establishing amounts.
Note: DocketMath helps you model calculations—not make court-verified outcomes. Use the figures that match your case filings (income, dates, and custody details).
1) Open the correct calculator in DocketMath
- Go to the tool page: /tools/alimony-child-support
- Confirm the jurisdiction is set to South Dakota (US-SD)
- Start a new run so your assumptions don’t overwrite prior scenarios.
What you’ll see: South Dakota-specific rules are applied based on the selected jurisdiction, using the statutory framework courts use to set amounts.
2) Enter the parties’ income inputs
South Dakota calculations depend on the parties’ financial circumstances. The statutes describe that the court determines the amount of both alimony and child support based on the applicable framework and considerations.
Use DocketMath’s income fields (typically):
- Obligor income (the parent/spouse paying support)
- Recipient income (the parent/spouse receiving support)
- Any additional income components the tool asks for (if available)
Tip: If your case includes an income change (new job, reduced hours, end of overtime), model the scenario you want to compare. Keep a second run for “before” vs. “after” changes.
3) Add child-related inputs (custody / arrangement)
Next, complete the child support portion inputs. In DocketMath, these usually include:
- Number of children
- Parenting time / custodial allocation (how the time is split, if the tool supports it)
- Any other child-specific flags the calculator requests
Because alimony and child support are determined within the same overall statutory context, custody-related inputs can materially affect the child support output (and therefore your combined total).
4) Add alimony-specific inputs
Now complete the alimony parameters. DocketMath typically asks for:
- Whether you’re modeling alimony (or if alimony is requested)
- Duration / timing assumptions (if required by the tool)
- Any other alimony inputs the calculator supports
Jurisdiction anchors (South Dakota):
- Alimony: S.D. Codified Laws § 25-4-41
- Child support: S.D. Codified Laws § 25-7-6.2
5) Confirm the “default” period settings clearly
If the tool includes time period controls (such as a default calculation period), verify what they mean for South Dakota.
Important clarification for this guide:
No claim-type-specific sub-rule was found in the jurisdiction data provided. That means this walkthrough should treat the tool’s general/default period as the controlling assumption.
So:
- Use the tool’s standard/default time handling unless your specific scenario instructs otherwise.
- If DocketMath offers “adjust” or “custom” time-period settings, treat those as scenario variables you control, not as hidden jurisdiction rules.
6) Run the calculation and review outputs
Press Calculate (or the equivalent button).
DocketMath should return a breakdown such as:
- Estimated child support amount
- Estimated alimony amount
- Combined monthly figure (if the tool provides it)
- Any intermediate values the tool shows (useful for auditing)
How outputs change when you change inputs:
- Raising the obligor’s income (or lowering the recipient’s income) typically increases support amounts in most calculation models.
- Changing parenting-time assumptions can change how the tool credits time and may shift the child support line item.
- Altering alimony duration or related eligibility assumptions can dramatically change the alimony portion.
7) Make scenario comparisons (recommended)
Don’t rely on a single run. Create at least two variations:
- Scenario A (baseline): current documented incomes and the parenting-time split you’re modeling.
- Scenario B (change): one updated fact (example: job change, reduced overtime, or different parenting-time assumption).
Then compare:
- Child support
- Alimony
- Combined monthly total
This approach helps you see which facts drive the biggest differences.
8) Document your assumptions for re-use
When you find a scenario you want to keep:
- Save it (if DocketMath provides saving/versioning)
- Record the key inputs:
- Income figures
- Number of children
- Parenting-time/custody allocation
- Alimony duration settings (if required)
When you update one fact later, rerun and compare deltas rather than rebuilding the scenario from scratch.
9) Cross-check against statutory anchors (for correctness sense-checking)
Use the statute references below to sanity-check why certain inputs matter.
- Child support framework: S.D. Codified Laws § 25-7-6.2
Source: https://sdlegislature.gov/Statutes/25-7-6.2 - Alimony framework: S.D. Codified Laws § 25-4-41
The provided statute text summary for the framework is:
“The amount of alimony and child support is determined by the court...”
That matches the overall purpose of the tool: it models structured, court-determined amounts using your entered facts.
Common pitfalls
Many calculation mistakes come from entering the right facts in the wrong place—or assuming tool defaults mean something different than they do.
- Wrong jurisdiction selected (make sure it’s US-SD)
- Outdated income figures (using last year’s pay when current income differs)
- Leaving out parenting-time details even when the calculator requests them
- Assuming the “default period” is claim-type-specific
- For this guide, treat the tool’s general/default period as controlling because no claim-type-specific sub-rule was found in the provided jurisdiction data.
- Not running at least one comparison scenario
- Focusing only on “combined” without checking the child support and alimony line items separately
Common data-format error: entering gross income when the tool expects net (or vice versa). If DocketMath labels inputs (gross vs. net), match the numbers exactly to those labels.
Try it
To run a South Dakota estimate right now:
- Open the calculator: /tools/alimony-child-support
- Choose South Dakota (US-SD) if prompted.
- Enter:
- Parties’ incomes
- Number of children
- Parenting-time/custody allocation inputs
- Alimony assumptions DocketMath requests
- Click Calculate
- Create at least one comparison run:
- Change one assumption only (income change, or parenting-time split)
Quick input checklist before you run:
- Income figures are current and match the tool’s required format
- Number of children is correct
- Parenting-time allocation matches your scenario
- Alimony inputs reflect your modeling assumptions (including duration if required)
- You’re using the tool’s general/default period for this walkthrough (no claim-type-specific sub-rule was identified from the provided jurisdiction data)
When you’re done, save the scenario and record:
- Estimated child support
- Estimated alimony
- Combined monthly estimate (if shown)
