Child support represents one of the most important financial responsibilities parents face after separation or divorce. In South Carolina, both parents share the legal obligation to financially support their children, regardless of their relationship status or living arrangements. Whether you're paying child support, receiving it, or just beginning to learn about your obligations, knowing how the system works helps ensure your children get the support they deserve.
What Is South Carolina Child Support?
Child support is money one parent pays to another parent to help cover the costs of raising their shared children. This financial support covers necessities like food, clothing, and shelter, plus additional expenses such as healthcare, education, childcare, and extracurricular activities.
South Carolina law is clear: both parents have a legal duty to support their minor children. Under state code, this obligation actually begins at conception. This means biological fathers can be ordered to pay half of pregnancy-related expenses, including a portion of the mother's health insurance premiums not covered by her employer or government programs.
Who Pays Child Support?
Typically, the non-custodial parent pays child support to the custodial parent. The custodial parent is the one with whom the child primarily lives. You don't need formal legal custody to be considered a custodial parent. The child simply needs to reside with you most of the time.
The amount the non-custodial parent pays depends on several factors, including both parents' incomes, the number of children, custody arrangements, and various expenses we'll explore throughout this guide.
How South Carolina Calculates the Amount of Child Support
South Carolina uses the Income Shares Model to determine child support obligations. This research-based approach recognizes that parents in intact families typically spend money on their children in proportion to their income. The model ensures children receive the same share of parental income they would have gotten if their parents still lived together.
The South Carolina Child Support Guidelines
The South Carolina Child Support Guidelines, updated and effective January 15, 2024, provide the formulas and tables courts use to calculate support. These guidelines were developed by the Department of Social Services (DSS) and ensure consistency and fairness across the state.
The guidelines consider both parents' gross monthly income and use tables showing the total basic support obligation based on combined income and the number of children. That total obligation then gets divided between parents in proportion to each person's percentage of their combined incomes.
For example, if Parent A earns 70% of the combined household income and Parent B earns 30%, Parent A would be responsible for 70% of the total support obligation while Parent B would owe 30%. Since the child typically lives with one parent, the other parent pays their portion as child support payments to the custodial parent.
Factors That Determine Child Support Payments
Several key factors influence the final amount:
Both Parents' Incomes
The calculation starts with each parent's gross monthly income, including salaries, wages, commissions, bonuses, self-employment income, rental property income, Social Security benefits (excluding SSI), disability payments, unemployment benefits, workers' compensation, veterans' benefits, pensions, retirement distributions, and alimony received.
Number of Children
The more children requiring support, the higher the total obligation. The guidelines account for one to six children, with adjustments for larger families.
Custody Arrangements
How much time each parent spends with the children significantly impacts payments. More parenting time typically results in lower financial obligations because that parent is already directly providing for the children during their time together.
Health Insurance
The cost of providing health insurance coverage for the children factors into the calculation. The parent providing coverage receives a credit on their support obligation.
Work-Related Childcare
Reasonable daycare or after-school care expenses that allow parents to work are divided between parents proportionally to their incomes.
Extraordinary Medical Expenses
Medical costs exceeding $250 per year per child that insurance doesn't cover may be added to the basic support obligation.
Other Financial Obligations
Prior child support obligations, alimony payments, and support for other children living in each parent's home can affect the calculation.
Average Child Support Payment Amounts
While every case is unique, average monthly child support payments in South Carolina range from $793 to $1,628 for parents with one to six children. These averages are based on South Carolina's median household income of approximately $67,800.
For example, a non-custodial parent earning $3,000 monthly with three children might pay approximately $762.67 per month. A parent earning $5,000 monthly with two children might pay around $1,100 to $1,200.
Courts typically won't set the amount of child support below $100 per month, even for low-income parents. The guidelines include a self-support reserve of $1,010.50 per month, ensuring the paying parent retains at least this amount to cover their own basic living expenses.
How to Apply for South Carolina Child Support
Any parent with physical custody of a child who needs assistance obtaining child support payments can apply for services. You don't need formal legal custody. The child simply needs to live with you.
Application Process
It's free to apply for child support services through the South Carolina Department of Social Services. Parents receiving Temporary Assistance for Needy Families (TANF) automatically receive services. If you don't receive TANF, complete an application form available at regional Child Support offices, county DSS offices, county clerk of court offices, or online through the Child Support Customer Service Portal.
Non-custodial parents can also apply to have paternity established if the parents were never married. Before a child support order can be issued, paternity must be confirmed through a signed acknowledgment, DNA testing, or legal determination by the court.
Timeline for Obtaining a Child Support Order
When the non-custodial parent is located and served with notice, obtaining a support order usually takes less than three months. It may take longer if the non-custodial parent lives out of state or proves difficult to locate.
DSS will schedule a negotiation conference or court hearing to establish child support. If you live in South Carolina and have custody, you must attend the conference or hearing. If the non-custodial parent lives out of state and a hearing is scheduled there, you aren't required to attend that out-of-state hearing, but you may need to attend a conference with DSS.
How Custody Arrangements Affect Support Obligations
The amount of time children spend with each parent significantly impacts child support calculations. The more overnights a parent has per year, the lower that parent's financial obligation becomes because they're already providing for the children during that time.
Shared Custody Adjustments
When parents have shared physical custody, meaning each has the children for more than 109 overnights during the year, judges may apply adjustments to the standard calculation. The shared custody adjustment recognizes that both parents incur direct expenses when children stay with them.
However, judges must ensure this adjustment won't seriously and negatively affect the children's standard of living. The goal is to maintain consistency for children while fairly distributing financial responsibility between parents.
Split Custody
When parents have split custody, where each has custody of at least one child, the guidelines use separate calculations for children living with each parent. The parent with the larger support obligation pays the difference to the other parent.
Importance of Accurate Parenting Time
Calculating parenting time accurately matters tremendously. Even a difference of 10 or 20 nights per year can change support amounts by hundreds of dollars monthly. Keep detailed calendars showing when children stay with each parent, accounting for regular weekly schedules, holidays, and summer breaks.
When Courts Can Deviate from the Guidelines
South Carolina law presumes the amount calculated under the guidelines is correct. However, judges may order higher or lower amounts if applying the standard calculation would be unjust or inappropriate based on specific circumstances.
Common Reasons for Deviation
Courts consider factors such as educational expenses for private schools or special needs education, equitable distribution of property in divorce, consumer debts, families with more than six children, unreimbursed extraordinary medical expenses for parents or children, mandatory deductions for retirement pensions and union fees, support obligations for other dependent children, monthly fixed payments imposed by court or law, significant income available to the child, and substantial differences between parents' incomes that make guideline amounts impractical.
When courts deviate from standard calculations, judges must provide written findings explaining their reasoning and note what the guideline amount would have been. This ensures transparency and provides grounds for appeal if either party believes the deviation was inappropriate.
How South Carolina Child Support Gets Paid
Child support in South Carolina is typically collected and enforced by the Child Support Services Division of the Department of Social Services. The non-custodial parent can pay child support in two ways: directly to the other parent or through the State Disbursement Unit (SDU).
Income Withholding
Often, judges or DSS order child support to be withheld from the paying parent's income through their employer. Employers must comply immediately with income withholding orders. Sometimes courts order payment differently, and income withholding only begins if the parent misses payments.
Fees and Administrative Charges
If you've never received public assistance (AFDC/TANF), you'll pay a $35 annual fee each federal fiscal year after collecting at least $500 in child support. This fee only applies once the $500 threshold is met.
When payments go through the court, and the parent falls behind, an administrative fee of 5% gets added to the obligation. The clerk of the family court will issue a "bookkeeping" rule to show cause requiring the parent to appear and explain why they shouldn't be held in contempt.
What Happens When Parents Don't Pay Child Support
South Carolina strictly enforces child support obligations. Failing to pay court-ordered support carries serious consequences designed to ensure children receive the financial support they need and deserve.
Enforcement Mechanisms
The state uses multiple tools to collect unpaid support:
Income Withholding
Automatic deduction from wages, unemployment benefits, or workers' compensation.
Tax Refund Interception
Federal and state tax refunds can be seized to cover unpaid support.
License Suspension
The state can revoke driver's licenses, occupational licenses, and professional licenses.
Credit Reporting
Non-payment gets reported to credit agencies, damaging credit scores and making it harder to secure loans or housing.
Contempt of Court
Parents who don't pay face contempt charges resulting in fines up to $1,500, jail sentences up to one year, or 300 hours of community service. Judges often jail parents until they "purge" themselves by paying all or a portion of what they owe.
Federal Interstate Enforcement
If a parent moves out of state to avoid child support, they may face federal charges under the Deadbeat Parents Punishment Act of 1998. This federal law makes it a crime to willfully fail to pay support for a child in another state when the obligation has remained unpaid for more than one year or exceeds $5,000.
Penalties include up to six months in jail for a first offense and up to two years for subsequent offenses, plus mandatory payment of all unpaid support.
Modifying Child Support Orders
Life circumstances change, and South Carolina law recognizes that support obligations sometimes need adjustment. Either parent can request a modification if there has been a substantial or material change in circumstances.
Qualifying for Modification
Common reasons include significant changes in either parent's income, job loss or involuntary reduction in work hours, disability affecting earning capacity, changes in the child's needs such as new medical conditions or educational requirements, changes in parenting time arrangements, remarriage resulting in termination of alimony, or birth of additional children to either parent.
Simply showing income loss isn't always enough. Courts examine whether the parent seeking modification has taken reasonable steps to minimize expenses and maximize income given the current circumstances.
How to Request Modification
If DSS established your order, request a review by sending a written notice via certified mail to your caseworker, explaining the changed circumstances. If the agency agrees, it will send notice of the new amount to the parent paying support.
For orders not involving DSS, file a complaint for modification with the family court, providing your current support order, a financial declaration showing current circumstances, and evidence supporting your claim of substantial change.
Three-Year Review Option
Even without proving substantial change, either parent can request review if three years have passed since the order was established or last reviewed. DSS automatically reviews some cases every three years, particularly those involving families receiving government assistance.
When Child Support Obligations End
As a general rule, child support obligations end when the child turns 18, gets married, or becomes self-supporting, whichever happens first. However, several exceptions can extend this timeline.
Extensions Beyond Age 18
If an 18-year-old is still attending high school, support continues until graduation or the end of the school year when the child turns 19, whichever comes later. Judges may order support to continue for adult children with physical or mental disabilities or other exceptional circumstances.
Parents may also agree, or judges may order, that support continues beyond the legal cutoff date, such as to help pay for college expenses. South Carolina courts have held that judges may order parents to help pay adult children's college expenses when the child would benefit from higher education and shows the ability to succeed, the child couldn't otherwise afford college, and the parent can afford to contribute.
Termination Process
Child support doesn't automatically end when the child reaches the appropriate age. For court orders, the paying parent typically needs to petition for a dismissal order. For administrative orders through DSS, the agency stops the order and notifies both parents.
If you're paying support for multiple children, you may need to request a modification when the oldest child turns 18 or graduates, unless your order includes specific provisions for automatic reductions.
Special Considerations and Important Rules
In South Carolina, visitation rights are completely separate from child support obligations. A parent who fails to make child support payments still has the right to visit with their children, and the custodial parent cannot legally restrict access based on non-payment. The right to receive support belongs to the child, not the custodial parent.
Documentation Is Critical
If you pay child support directly to the other parent rather than through the State Disbursement Unit, document everything carefully. The burden of proof falls on you to show you made the required payments. Use checks or electronic payments that leave trails, get receipts, or have the other parent acknowledge receipt via text or email. Cash payments without receipts are extremely risky.
Credits for Disability Benefits
Parents receiving Social Security disability benefits or retirement benefits on behalf of a child are entitled to a credit against their support obligation for those amounts. These benefits paid on the child's behalf count toward fulfilling the support requirement.
Financial Hardship
If you're facing financial difficulties and can't make payments, don't just stop paying. Contact DSS or file a motion with the family court immediately to request a modification. Being proactive is the best way to avoid contempt charges and potential jail time. Courts understand that genuine hardships occur, but you must take action through proper legal channels.
