Child Support in South Carolina
Income shares is the model South Carolina uses to calculate child support. South Carolina Code section 63-17-470 authorizes it, and the Department of Social Services spells out the details in the South Carolina Child Support Guidelines regulation. Both parents' gross incomes get combined, then a statewide schedule applies to that total. The department splits the resulting obligation between the parents, based on each parent's share of the combined income. A family court case, like a divorce or paternity action, can set a South Carolina support order. A parent can also apply directly through the Department of Social Services' Child Support Services Division, which serves as the state's IV-D agency. Contested support matters go to South Carolina family courts. For parents who apply for its help, Child Support Services can also set up and enforce orders administratively.

The South Carolina income shares guideline
South Carolina courts combine both parents' gross incomes under section 63-17-470 and the South Carolina Child Support Guidelines. That combined figure maps to a basic obligation on the state's schedule. Each parent then owes a share of that obligation, proportional to their income.
Health insurance premiums and work-related child care costs factor into the guideline. A shared custody adjustment applies too, for cases where parenting time splits more evenly between the parents.
Applying through Child Support Services
Child Support Services Division, part of the South Carolina Department of Social Services, is the state's IV-D agency. Paternity establishment, a new support order, or enforcement of an existing one can all be requested through the department's website.
Support can also be decided directly inside an existing family court case, for a parent already litigating divorce, custody, or paternity.
Which court hears the case
Divorce, custody, and paternity cases that involve contested child support go to South Carolina family courts. In many cases, Child Support Services sets up support administratively instead. When a case turns contested, a parent can ask for a family court hearing.
Modifying a South Carolina order
A substantial or material change in circumstances since the order was set opens the door to modification in South Carolina. A significant change in income counts as one example. Orders under Child Support Services' enforcement also get periodic review, and the agency can pursue modification when the current guideline calculation comes out materially different.
To seek modification, a parent files with the family court that issued the order. For agency-managed cases, a parent can instead request a review through Child Support Services.
Enforcement
Standard IV-D enforcement tools back South Carolina orders through Child Support Services. Income withholding, state and federal tax refund interception, credit bureau reporting, and license suspension for significant arrears are all part of the toolkit.
Opening a case with the agency gets enforcement help for a parent who is owed support, even if the original order came out of a private family court filing.

Child Support in South Carolina: frequently asked questions
What model does South Carolina use for child support?+
South Carolina uses the income shares model, set out in South Carolina Code section 63-17-470 and the South Carolina Child Support Guidelines.

How do I apply for child support services in South Carolina?+

Which court hears child support cases in South Carolina?+
South Carolina family courts handle contested support matters tied to divorce, custody, and paternity cases. Administrative setup through Child Support Services is also an option, with family court review available if a case becomes contested.
How do I modify a South Carolina child support order?+
Show a substantial or material change in circumstances, such as a significant income change, and file with the family court that issued the order. For agency-managed cases, a periodic review through Child Support Services is another route.
Does shared custody affect a South Carolina child support calculation?+
Yes. South Carolina's guideline builds in a shared custody adjustment for arrangements where parenting time splits more evenly between the parents, so the support amount can land differently than a standard sole-custody calculation, depending on the actual parenting schedule.

Income withholding, state and federal tax refund interception, credit bureau reporting for arrears, and license suspension once a parent falls significantly behind: these are Child Support Services' tools.
