You cannot drop child support in South Carolina on your own. A child support order is a court order, and it stays in force until a Family Court judge signs a new one replacing or ending it. Even a written agreement between both parents has no legal effect until the court approves it. To reduce or terminate your obligation, you file a complaint in Family Court, pay the $150 filing fee, and prove either that circumstances have genuinely changed since the last order or that a legal event has ended your duty to pay.1South Carolina Judicial Branch.

Only Family Court Can End or Change the Order
The Family Court has exclusive authority to modify or terminate a South Carolina child support order.2South Carolina Legislature. South Carolina Code of Laws Title 63 Chapter 17 – Paternity and Child Support The Department of Social Services Child Support Services Division enforces orders but has no power to change them. Until a judge signs a new order, the existing one controls, payments keep accruing, and enforcement tools remain available to the other parent and to the state.
That means informal arrangements do not protect you. If the other parent tells you to stop paying, or if the child moves in with you, or if your income drops, none of that changes what you legally owe until the court says so.
Grounds to Modify Support
Section 63-17-310 of the South Carolina Code lets the Family Court modify a support order “as the court considers necessary upon a showing of changed circumstances.”3South Carolina Legislature. South Carolina Code of Laws Title 63 Chapter 17 – Paternity and Child Support – Section 63-17-310 The change has to be something new since the last order. Common grounds include:
- A significant income change for either parent — a job loss, a disability, or a substantial raise.
- New expenses for the child, such as medical needs or special education costs that did not exist before.
- A shift in physical custody or parenting time that changes each parent’s day-to-day financial responsibility.
- Incarceration of the paying parent, though this alone does not guarantee a reduction.
File as soon as the change happens. No modification can reach back and erase installments that came due before the modification action was filed and served.3South Carolina Legislature. South Carolina Code of Laws Title 63 Chapter 17 – Paternity and Child Support – Section 63-17-310 Wait six months after losing your job and you still owe the full original amount for those six months.
When the Obligation Ends
Child support in South Carolina generally runs until the child turns 18. Once the child is emancipated or reaches 18, the noncustodial parent may petition the court for a dismissal order, according to the Department of Social Services.4South Carolina Department of Social Services. Child Support FAQ The court can continue support beyond 18 if the child is still in school or other circumstances justify it.
Marriage, military enlistment, or the child becoming financially self-supporting can also end the obligation. In every case, the order does not vanish on its own. You still have to go to court and get a formal termination. Payments keep accruing until a judge signs the new order.
How to File
Get the Right Forms
South Carolina uses self-represented litigant packets for support modifications, and the filings are complaints, not motions. The main forms are SCCA 400.21 (Complaint to Decrease Child Support) and SCCA 400.31 (Complaint to Increase Child Support), both available on the South Carolina Judicial Branch website.5South Carolina Judicial Branch. SRL Child Support Modification Packets For a termination based on the child aging out or emancipating, ask the Family Court Clerk in your county for the correct form.
Gather Documentation
Bring recent pay stubs, two to three years of tax returns, proof of any other income, bank statements, health insurance premium costs, and childcare expenses. Include a copy of the current support order and any related custody orders. The most important evidence is proof of the change itself: a termination letter and job-search records if you lost your job, medical records and bills if the child has new health needs, or proof of age and school completion if the child has aged out.
File, Pay, and Serve
File the complaint and supporting documents with the Family Court Clerk. The filing fee is $150, and you can request a waiver if you cannot afford it.1South Carolina Judicial Branch. Family Court Filing Fees After filing, you have to formally serve the other parent. South Carolina’s Rules of Civil Procedure allow personal delivery by anyone over 18 who is not a party, service by the sheriff or a law enforcement officer, certified mail with return receipt restricted to the addressee, or a commercial delivery service.6South Carolina Judicial Branch. South Carolina Rules of Civil Procedure – Rule 4 If you use certified mail, a default judgment can only be entered if the return receipt shows the other parent personally accepted delivery.
Mediation and Hearing
South Carolina generally requires mediation in contested family court cases before a final hearing is scheduled. If mediation produces an agreement, it goes to the judge for approval. Otherwise the case proceeds to a hearing where the judge decides based on the child’s best interests and the changed circumstances you have shown. If the court grants your request, a new order replaces the old one. Send a copy to the DSS Child Support Services Division so their records match.
Two Mistakes That Sink These Cases
Quitting or Underworking to Cut the Number
If you voluntarily leave a well-paying job or deliberately cut your hours before a support hearing, the court does not have to use the smaller number. South Carolina’s guidelines let the judge impute income, calculating support on what you are capable of earning rather than what you are actually earning. Judges look at your education, work history, professional licenses, skills, and the local job market. Quit a $70,000 job for a $25,000 part-time position right before a hearing and the court will likely base support on the $70,000 figure. Courts rarely impute less than full-time minimum wage, even for parents with limited work history.
Legitimate reasons for a lower income exist. A genuine disability with medical documentation, an involuntary layoff with an active job search, or enrollment in education that will raise your earnings can all support using actual income. The burden is on the parent with the reduced income to show the drop was not strategic.
Letting Arrears Build Up
Past-due support is nearly impossible to erase. Under 42 U.S.C. § 666(a)(9), every child support payment becomes a judgment by operation of law on the date it comes due, and no state can retroactively modify it.7Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures Even if you win a reduction going forward, everything you already owed remains a legal judgment.
Bankruptcy will not clear it. Federal bankruptcy law lists domestic support obligations as debts that cannot be discharged.8Office of the Law Revision Counsel. 11 USC 523 – Exceptions to Discharge Chapter 7 or Chapter 13 may wipe out credit cards and medical bills, but child support arrears survive intact. The only way past-due support disappears is if the parent owed it voluntarily forgives it.
What Happens If You Just Stop Paying
Walking away from an order without filing to modify it triggers a fast-escalating enforcement response. Income withholding is the most immediate tool: support is deducted directly from wages or unemployment benefits.9South Carolina Department of Social Services.

If You or the Other Parent Live Out of State
Under the Uniform Interstate Family Support Act, South Carolina keeps exclusive authority to modify its own support order as long as the child, the paying parent, or the receiving parent still lives here. Another state cannot change the dollar amount while South Carolina holds that jurisdiction, though any state can enforce the existing order by garnishing wages or collecting arrears. If everyone has left South Carolina, another state may take over modification authority, but specific steps have to be followed to transfer jurisdiction. If you have moved and need to modify, talk to a family law attorney about which state’s court to file in.
