South Carolina Single Mom Guide: Custody Laws, Child Support, Benefits, and Legal Help
South Carolina uses an income shares model for child support, has a family court system that handles all domestic matters, and did not expand Medicaid under the ACA — a significant gap that affects health coverage options for many single mothers in the state. South Carolina also has a distinctive fault-based divorce system that can intersect with custody proceedings. Here’s what single mothers in South Carolina need to know.
South Carolina Child Support
South Carolina uses the Income Shares model, calculating child support based on both parents’ gross income combined, the number of children, and child-related expenses.
Key South Carolina-specific facts:
- South Carolina calculates child support using combined gross monthly income of both parents. The South Carolina Child Support Guidelines (South Carolina Code § 63-17-470 and accompanying regulations) set the basic child support obligation based on combined income and number of children
- The guidelines apply to combined monthly gross incomes up to $30,000. Above that threshold, courts have discretion to set support based on the child’s needs and the parents’ ability to pay
- Parenting time adjustment: South Carolina’s guidelines include a shared custody adjustment when the non-custodial parent has the child for at least 109 overnights per year (approximately 30% of the year). Below that threshold, the standard formula applies; at or above 109 overnights, an adjustment reduces the basic obligation
- Healthcare costs for the child and work-related childcare are added to the basic obligation and shared proportionally
- Child support in South Carolina is enforced by the South Carolina Department of Social Services (DSS) Child Support Services Division. IV-D services are free
- Income withholding is the standard enforcement mechanism
- Child support in South Carolina continues until the child turns 18, or until age 19 if the child is still enrolled in high school and is expected to graduate before the age of 19
- South Carolina does not have statutory provisions for college support

South Carolina Custody Law
South Carolina uses legal custody and physical custody terminology and handles all family law matters in the Family Court, a specialized court within South Carolina’s circuit court system.
Key South Carolina-specific facts:
- South Carolina has no statutory presumption favoring either parent or either custody arrangement. Courts apply the best interest of the child standard
- South Carolina’s best interest factors are developed through case law rather than a comprehensive statutory list. Key factors from South Carolina’s leading cases include: the fitness of each parent, the character, fitness, and attitude of each parent, the conduct of each parent, each parent’s ability to provide for the child’s needs, the child’s preference (with age-appropriate weight), the child’s relationship with each parent, and the desirability of maintaining continuity
- Joint legal custody is available in South Carolina but courts historically have been more conservative about awarding it than many other states. When parents can cooperate effectively, joint legal custody is possible; sole legal custody remains common when cooperation is limited
- Physical custody arrangements range from primary custody with one parent and visitation for the other, to joint physical custody with equal or near-equal time. Courts have discretion to craft arrangements suited to each family
- The child’s preference: South Carolina case law considers the child’s preference with increasing weight as the child matures. There is no specific statutory age threshold; courts evaluate the child’s age, maturity, and the reasons behind the preference
- South Carolina’s fault-based elements: South Carolina recognizes fault in divorce proceedings (adultery, physical cruelty, habitual drunkenness, desertion), and while custody is determined by the best interest standard, evidence of fault — particularly regarding fitness as a parent — can be relevant to custody proceedings
- Relocation: South Carolina does not have a specific relocation statute. Relocation disputes are handled under the general modification standard — the relocating parent must show a substantial change in circumstances and that the move is in the child’s best interest. Courts evaluate the totality of circumstances
- Domestic violence: South Carolina’s best interest analysis considers domestic violence as a significant factor affecting parental fitness. South Carolina also has a Protection from Domestic Abuse Act that provides for protective orders, which can include temporary custody provisions

South Carolina Benefits and Assistance Programs
South Carolina Medicaid
South Carolina did not expand Medicaid under the ACA and remains one of a small number of non-expansion states. This creates a significant coverage gap:
- Adults without dependent children do not qualify for South Carolina Medicaid regardless of income
- Parents qualify for South Carolina Medicaid at very low income thresholds — significantly below the poverty level
- Children qualify for Medicaid or CHIP (South Carolina’s program is called Partners for Healthy Children for CHIP-eligible children) at higher income thresholds than adults
- The ACA marketplace at healthcare.gov is the primary option for adults who don’t qualify for Medicaid in South Carolina. Premium tax credits are available for households above the poverty level; adults in the coverage gap (income below 100% FPL who don’t qualify for Medicaid) have very limited options
- Apply for Medicaid through the South Carolina Department of Health and Human Services (DHHS) at scdhhs.gov or through your local county DSS office
SNAP (Supplemental Nutrition Assistance Program)
South Carolina administers SNAP through the Department of Social Services. Apply online at dss.sc.gov or at your local DSS county office.
TANF (South Carolina Family Independence Program — FIP)
South Carolina’s TANF program is called the Family Independence Program (FIP):
– South Carolina has a 24-month time limit within any 10-year period — more restrictive than the federal 60-month limit
– Work requirements apply and are enforced; South Carolina requires participation in approved work activities relatively quickly
– South Carolina’s FIP benefit levels are among the lowest in the country
– Apply through your local county DSS office or dss.sc.gov
Child Care Assistance
South Carolina’s childcare subsidy is administered through the DSS Child Care Program. Eligibility is income-based for working or training families. Apply through your local county DSS office.
Additional South Carolina programs:
– WIC — apply through your local county health department or DHEC (Department of Health and Environmental Control) WIC office
– LIHEAP / Low Income Home Energy Assistance Program — administered through local community action agencies; apply in the fall for winter heating assistance
– SC Housing — schousing.com — South Carolina State Housing Finance and Development Authority; administers rental assistance and homebuyer programs
– South Carolina 2-1-1 — dial 2-1-1 for local resource referrals

South Carolina-Specific Points Worth Knowing
Medicaid non-expansion is a significant gap: South Carolina’s decision not to expand Medicaid means that many single mothers in South Carolina — particularly those working low-wage jobs without employer health insurance — fall into a coverage gap where they earn too much to qualify for traditional Medicaid but too little to qualify for meaningful ACA marketplace subsidies (which start at 100% of the federal poverty level). If you’re in this gap, SC Thrive and your local community health center (FQHC) are important resources. FQHCs provide primary care on a sliding-scale fee regardless of insurance status.
South Carolina’s 24-month FIP time limit: South Carolina’s 24-month within 10 years limit on cash assistance is more restrictive than the federal TANF 60-month lifetime limit. If you access FIP in South Carolina, the 24-month clock matters more immediately than in states using the full federal limit.
South Carolina Family Court: All domestic relations matters — divorce, custody, child support, adoption, and juvenile matters — go through South Carolina’s Family Court. This is a specialized court that handles only these matters, which means judges typically have significant family law experience. Finding the Family Court in your county is the starting point for any legal family matter.
Fault-based divorce elements: South Carolina has both fault and no-fault grounds for divorce. The no-fault ground (one year of continuous separation) is commonly used, but fault grounds (adultery, physical cruelty, habitual drunkenness or drug use, and desertion) can be raised. Adultery in particular has a specific implication in South Carolina — it can bar alimony for the adulterous spouse. While custody is determined by the best interest standard, evidence relevant to fault can surface in custody proceedings when it bears on parental fitness.
The 109-overnight shared custody threshold: South Carolina’s parenting time adjustment in child support becomes active at 109 overnights per year — approximately 30% of the year. Below that threshold, the standard formula applies without adjustment. This specific number can become a point of discussion when negotiating parenting schedules.
SC Thrive for benefits navigation: SC Thrive is a South Carolina-specific organization that helps residents identify and access benefits they qualify for — particularly important in a state where the benefits landscape is more limited than many others and where navigating available programs requires more local knowledge.
