How To Modify Child Support In South Carolina

Frequently Asked Questions
What qualifies as a substantial change in circumstances for child support in SC?
Common qualifying changes include significant job loss or income reduction, a substantial raise for either parent, changes in custody or parenting time, a child’s new medical or educational needs, and situations where the current order deviates more than 15% from the recalculated Guidelines amount.
Can I just stop paying if I lose my job?
No. You must continue paying the current court-ordered amount until a judge approves a modification. Stopping payments on your own can result in contempt of court, wage garnishment, and other enforcement actions. File for modification as soon as possible after a job loss.
How long does a child support modification take in South Carolina?
The timeline varies by county and case complexity. In Richland and Lexington counties, a straightforward modification may take 2 to 4 months from filing to hearing. Contested cases with disputed income or complex financial situations can take longer.
Can parents agree to change child support without going to court?
No. Parents may agree on a different amount, but the existing court order remains enforceable until a judge signs a modified order. Informal agreements can create significant problems if disputes arise later.
Circumstances often change after a child support order is entered. You may lose your job, receive a significant promotion, or see your custody arrangement change. When your circumstances shift substantially, your child support order may no longer reflect reality.
The good news: South Carolina law allows either parent to petition the family court to modify child support. The key requirement is proving a substantial change in circumstances since the original order was entered.
At Warner Law, we regularly help parents in Columbia and throughout the Midlands navigate the modification process. Here’s what you need to know about how to change child support in South Carolina.
A child support modification allows a court to increase, decrease, or otherwise adjust an existing support order when significant changes occur after the original order was entered. South Carolina courts require proof that circumstances have materially changed before approving a modification.
What Qualifies As A Substantial Change In Circumstances For Child Support Modification?
South Carolina courts won’t modify a child support order simply because one parent wants to pay less or receive more. You must demonstrate a meaningful, material change since the current order was issued.
Common grounds for modification include:
Income Changes
- Involuntary job loss or layoff
- Significant reduction in income (e.g., from a career change, disability, or industry downturn)
- Substantial increase in income for either parent
- A parent becoming self-employed with different income levels
A significant increase in the receiving parent’s income may also justify reviewing an existing child support order, depending on how the increase affects the support calculation under current Guidelines.
Changes in the Child’s Needs
- New medical conditions or ongoing healthcare needs
- Special education requirements
- Significant changes in childcare costs
Custody and Parenting Time Changes
- A change in the primary custody arrangement
- Significant increase or decrease in overnight visitation
- A child moving in with the other parent
The South Carolina 15% Child Support Rule
The 15% Rule
Under the SC Child Support Guidelines, if the current order differs by more than 15% from the amount that would be calculated under the Guidelines using current incomes, that difference alone may justify a modification.
Important: Remarriage alone is generally not sufficient grounds for modification. However, a new spouse’s income can sometimes be relevant if it frees up the parent’s income or affects household expenses.
The Modification Process: Step by Step
1. Gather Your Evidence
Before filing, collect documentation that supports your claim of changed circumstances:
- Pay stubs, tax returns, and W-2s (yours and, if possible, the other parent’s)
- Termination letters or unemployment records (for job loss)
- Medical records and bills (for changes in the child’s needs)
- Custody order or parenting plan (if custody has changed)
- A recalculated Guidelines worksheet showing the proposed new amount
2. File a Petition with the Family Court
You (or your attorney) must file a Petition for Modification with the family court in the county where the original order was issued. In the Columbia area, this is typically Richland County Family Court or Lexington County Family Court.
The petition must clearly state:
- The existing child support order
- The specific changed circumstances
- The proposed new support amount
3. Serve the Other Parent
The other parent must be formally served with the petition and given an opportunity to respond. They have 30 days to file a response.
4. Attend a Hearing
If the parents can’t agree on the new amount, the court will schedule a hearing. Both sides present evidence about income, expenses, and the child’s needs. The judge then recalculates support using the current child support calculation formula.
5. Receive the Modified Order
If the court approves the modification, a new order is issued. The modified amount typically takes effect from the date the petition was filed, not the date the hearing occurs — so file promptly.
Can Child Support Be Modified Retroactively?
Generally, South Carolina courts cannot retroactively modify child support to a date before a modification action is filed. This means that even if your circumstances changed months ago, the court usually cannot reduce support for periods before the filing date. For that reason, parents should file for modification as soon as a qualifying change occurs.
Critical Mistakes to Avoid
Never Stop Paying Without a Court Order
This is the most important rule in child support modification: you must keep paying the current amount until a judge officially changes it. Even if you’ve lost your job, even if both parents agree to a different amount, the original court order remains in effect until it’s formally modified.
Stopping payments or reducing them on your own can result in:
- Contempt of court proceedings
- Wage garnishment and tax intercepts
- Driver’s license suspension
- Accumulation of arrears with interest

Don’t Wait to File
If your circumstances have changed, file for modification as quickly as possible. Courts generally can’t make modifications retroactive to before the filing date. Every month you delay is a month you’re locked into the current amount.
Don’t Rely on Informal Agreements
A handshake deal with your co-parent to change the support amount isn’t enforceable. If the other parent later changes their mind, you could be on the hook for the full original amount — including any “reduced” payments that are now treated as arrears.
