5. CHILD SUPPORT OBLIGATION FORMULA

The steps below summarize Worksheet A only. For split or qualifying shared physical custody, complete the applicable official Worksheet B or C and record its result in the summary. For an obligor within the schedule’s shaded self-support-reserve area, use the applicable obligor-only method under § 114-4720(A)(11), rather than adding the other parent’s income or ordinary medical/day-care adjustments.

Step 1: Combined Adjusted Gross Income: $[________]

Step 2: Basic Child Support Obligation from SC Schedule (for [__] children): $[________]

Step 3: Each Parent's Share of Combined Income:

• Father: [____]%
• Mother: [____]%

Step 4: Add Health Insurance, Extraordinary Medical, and Child Care:

• Extraordinary Medical Expenses: $[________]
• Work-Related Child Care (adjusted): $[________]
• Total Child Support Obligation: $[________]

Step 5: Each Parent's Obligation:

• Mother: $[________] x [____]% = $[________]

Step 6: Credits:

• Less: Work-Related Child Care paid by obligor: ($[________])
• Less: Regular extraordinary medical expense paid by obligor and already included in the calculation: ($[________])

Net Monthly Child Support Obligation: $[________]

6. HEALTHCARE EXPENSES

The basic schedule includes $250 per child per year in uninsured medical expenses. Reasonable and necessary amounts above that level are shared in proportion to combined monthly adjusted gross income under § 114-4720(A)(12). Readily determinable, regularly incurred extraordinary expenses belong in the monthly calculation under (A)(13) and must not also be claimed for separate reimbursement.

10. DURATION AND TERMINATION

Under S.C. Code § 63-3-530(A)(17), the ordinary child-support order runs until age 18, marriage or self-support as determined by the court, whichever occurs first. The statute preserves high-school continuation, a preexisting agreement or order for support beyond 18, and discretionary continuation for physical or mental disability or other exceptional circumstances.

For a child still enrolled and attending high school, the statutory school limit is graduation or the end of the school year after the child reaches 19, whichever is later. Record the actual order and applicable branch; do not treat the eighteenth birthday as an automatic end in every case.

Existing duration provision and selected branch: [ORDER PARAGRAPH / FACTS / DATE]

Requested termination or continuation date and basis: [DETAILS]

11. STATE-SPECIFIC NOTES

• Self-Support Reserve: $1,010.50/month (2024). When the obligor's income falls in the shaded area of the schedule, use obligor's income only.
• Shared physical custody: Section 114-4730(A) requires more than 109 annual court-ordered overnights with each parent and contributions to expenses. Court approval depends on the actual circumstances and impact on the child’s standard of living. The regulation’s graduated adjustment applies above 109 but below 128 overnights; later qualifying counts use the full shared calculation. Complete the current official Worksheet C and its instructions.
• Income Imputation: The court considers assets, employment history, job skills, education, age, health, criminal record, and local job market per § 114-4720(A)(5).
• Guideline review: S.C. Code § 63-17-470(D) requires review at least once every four years. Identify the current guideline edition and worksheet used for this calculation.
• Income verification: Under § 114-4720(A)(6), the court ordinarily uses verified financial declarations. Current earnings documentation, preferably at least one month, and recent tax returns may support or resolve the income figures; not every listed record is a universal attachment requirement.
