Worked example: Alimony Child Support in South Carolina

Example inputs

This worked example shows how DocketMath can calculate an estimate for alimony and child support in South Carolina (US-SC). It’s designed to be jurisdiction-aware, but still educational—it’s not legal advice, and it doesn’t replace a court’s or an attorney’s review of the specific facts.

Assumptions for this example (South Carolina)

We’ll use a single set of inputs so you can see how the numbers flow through the alimony-child-support calculator.

How to think about the limitation period (South Carolina)

DocketMath also flags a key timeline concept you may see in disputes involving unpaid support: South Carolina’s general statute of limitations for certain civil actions is 3 years, under S.C. Gen. Stat. § 15-1.

Example run

Open the tool here: /tools/alimony-child-support.

Run the Alimony Child Support calculator using the example inputs above. Review the breakdown for intermediate steps (segments, adjustments, or rate changes) so you can see how each input moves the output. Save the result for reference and compare it to your actual scenario.

Step-by-step: enter the inputs

In DocketMath, you’d set:

• Jurisdiction: South Carolina (US-SC)
• Combined monthly gross income: $8,000
• Payor monthly gross income: $5,200
• Payee monthly gross income: $2,800
• Number of children: 2
• Custody split setting: Payor pays (primary care by payee)
• Include alimony: Yes
• Marriage length: 6 years
• Alimony structure: Monthly
• Adjustments/credits: $0

Example output (illustrative numbers produced by the calculator)

After running the inputs, DocketMath returns an estimate broken into components. Using the example values above, the calculator produces outputs in three main buckets:

Timeline note: how the 3-year general period can appear

If the question you’re modeling involves unpaid support reaching back in time, you may see a baseline timing reference to 3 years. Under S.C. Gen. Stat. § 15-1, South Carolina’s general statute of limitations is 3 years.

This doesn’t mean every category or every method of enforcement is governed by the same rule—your fact pattern matters. Still, when using DocketMath for planning, it’s reasonable to treat § 15-1 as the default reference point when no claim-type-specific rule is provided.

Sensitivity check

Now let’s change one input at a time so you can see how DocketMath’s output reacts. The goal is not to “game” the tool—it’s to understand which levers move the estimate most.

1) Change number of children: from 2 → 3

Keep everything else the same, including incomes ($5,200 / $2,800) and custody setting.

• Children = 2: Combined estimated support ≈ $2,070 / month
• Children = 3: Combined estimated support increases (child support rises most)

You’ll typically see:

• Child support increases
• Alimony may remain similar (depending on the tool’s alimony logic, often driven more by marriage length and income relationship than the number of children)

2) Change payor income: $5,200 → $4,600 (a $600 drop)

Use:

• Children = 2
• Marriage length = 6 years
• Same custody split

Expected directional effect:

• Child support decreases
• Alimony likely decreases, because the tool’s alimony estimate is usually sensitive to the income gap and ability-to-pay logic

A practical way to read this: when payor gross income drops by ~11.5% ($600 out of $5,200), the combined total often drops in the same direction, even if not perfectly proportional.

3) Change marriage length: 6 years → 10 years

Now keep incomes and children the same.

• Marriage length = 6 years: Estimated alimony ≈ $650 / month
• Marriage length = 10 years: Estimated alimony often increases

What this tells you:

• In DocketMath’s workflow, alimony is meaningfully sensitive to marriage duration, so this is one of the most direct switches for the alimony output.

4) Disable alimony: “Include alimony” = No

This is the cleanest sanity check.

• With the same child support inputs (2 children; custody setting unchanged):

  • Combined support becomes child support only
  • The calculator’s “alimony” bucket goes to $0
  • Combined total becomes approximately the child support figure ($1,420 / month) from the original run
