How to Modify Child Support in Georgia
Reviewed by DocDraft Legal Team · Georgia · Last updated September 21, 2026
In Georgia, a child support modification is a court or the state child support agency changing an existing support order after a substantial change in either parent's income and financial status or the needs of the child (O.C.G.A. 19-6-15(k)). Unlike states that set a fixed percentage you must clear, Georgia applies that substantial-change standard rather than a numeric trigger. Support is set by a statewide guideline based on both parents' incomes (O.C.G.A. 19-6-15), so a job loss, a raise, or a change in the child's needs can make the current amount too high or too low. You can ask for a change in two ways. You can file a petition for modification in the Superior Court of the county where the other parent resides, or, if your case is with the Division of Child Support Services (DCSS), you can ask that agency to review the order at no charge. Georgia limits repeat filings: you generally cannot file a new modification within two years of a prior modification order, unless a listed exception applies, such as an involuntary loss of income (O.C.G.A. 19-6-15(k)(2)). A modification generally applies going forward, so keep paying your current order until it is changed. You can also request a review about every three years.

How do I modify child support in Georgia?
File a petition for modification in the Superior Court of the county where the other parent lives, or ask the Division of Child Support Services to review your case if the agency manages it. You must show a substantial change in either parent's income and financial status or the child's needs (O.C.G.A. 19-6-15(k)).
How much does income have to change to modify child support in Georgia?
Georgia sets no fixed percentage for the modification standard itself; you must show a substantial change in either parent's income and financial status or the needs of the child (O.C.G.A. 19-6-15(k)). A separate rule protects a parent who suffers an involuntary income loss of 25 percent or more.
How far back can a child support change go in Georgia?
A modification generally applies going forward, not back to your circumstances or your filing date. The one statutory exception is an involuntary income loss of 25 percent or more, where the support attributable to that lost income does not accrue from the date the other parent is served (O.C.G.A. 19-6-15(j)). Keep paying until the court rules.
Which court handles child support modifications in Georgia?
The Superior Court in the county where the other parent resides handles a petition to modify child support. If the Division of Child Support Services manages your case, you can instead ask that agency to review and, if warranted, seek a new order. Both paths apply the statewide child support guideline (O.C.G.A. 19-6-15).
Georgia child support modification at a glance
In Georgia, a child support modification is a court or the Division of Child Support Services changing an existing support order after a substantial change in either parent's income and financial status or the needs of the child (O.C.G.A. 19-6-15(k)). Georgia does not use a fixed percentage trigger; it applies that substantial-change standard. You file a petition for modification in the Superior Court where the other parent resides, attaching the Georgia child support worksheet, or ask DCSS to review the order for free. You generally cannot refile within two years of a prior modification order unless an exception applies, such as a 25 percent involuntary income loss (O.C.G.A. 19-6-15(k)(2)). A change generally applies going forward, so support that already came due is not erased.
Lowering a Georgia order after an involuntary pay cut
Suppose you lost your job in Georgia and your income fell by more than 25 percent, which lets you seek a modification even within two years of a prior order (O.C.G.A. 19-6-15(k)(2)). You prepare a petition for modification with the Georgia child support worksheet showing your lower income, and file it in the Superior Court where the other parent resides. You have the other parent served promptly, because for a 25 percent involuntary income loss the support attributable to that lost income stops accruing from the date of service (O.C.G.A. 19-6-15(j)). You keep paying your current order until the judge rules. At the hearing the court recalculates support under the guideline and signs a new order. Attorney review of your filing is available through DocDraft.
Relevant Laws
O.C.G.A. 19-6-15 (child support guideline and modification)
Sets Georgia's statewide child support guideline based on both parents' incomes, and in subsection (k) provides that a parent may petition to modify only on a substantial change in either parent's income and financial status or the needs of the child, and generally not within two years of a prior modification order except for listed exceptions.
O.C.G.A. 19-6-15(j) (involuntary loss of income)
Provides that where a parent suffers an involuntary loss of income of 25 percent or more, the portion of child support attributable to the lost income shall not accrue from the date of service of the petition for modification, provided the other parent is served. This is the operative event that limits how far a reduction reaches back.
O.C.G.A. 19-6-19 (revision of a support judgment)
Provides that a support judgment is subject to revision upon a petition showing a change in the income and financial status of a party, and sets the petition-and-hearing framework for revising an existing support award in Georgia.
Georgia Division of Child Support Services: review and modification
The Georgia DCSS explains the free administrative review path for parents whose case is managed by the agency, including requesting a review of the order for a substantial change and periodic review about every three years. The official child support calculator and worksheet are provided by the Georgia Child Support Commission at csc.georgiacourts.gov.
Regional Variances
Georgia child support modification rules at a glance
Qualifying threshold
Georgia sets no fixed percentage; you must show a substantial change in either parent's income and financial status or the needs of the child (O.C.G.A. 19-6-15(k)). You generally cannot refile within two years of a prior modification order unless a listed exception applies.
Where to file
The Superior Court of the county where the other parent resides handles a petition to modify. If the Division of Child Support Services manages your case, you can instead ask that agency to review the order for free.
Modification form
Georgia has no single statewide petition form. You file a petition for modification with the mandatory Georgia child support worksheet and a domestic relations financial affidavit. The official calculator is at csc.georgiacourts.gov.
Retroactivity
A change generally applies going forward, not back to filing. The only statutory exception is a 25 percent involuntary income loss, where the affected support does not accrue from the date the other parent is served (O.C.G.A. 19-6-15(j)).
Periodic review
If the Division of Child Support Services handles your case, you can generally request a review about every three years under federal rules, and sooner when a substantial change occurs.
Suggested Compliance Checklist

Before you file days after startingCollect current pay stubs, tax returns, and proof of the change, such as a job loss or an income change, and estimate the new guideline amount (O.C.G.A. 19-6-15). Attorney review of your filing is available through DocDraft.
Confirm the two-year rule does not block you
Before you file days after startingIf you filed a modification within the last two years, check whether an exception applies, such as an involuntary loss of income of 25 percent or more or a visitation issue, before you refile (O.C.G.A. 19-6-15(k)(2)).
Complete the petition and Georgia child support worksheet
As soon as your circumstances change days after startingPrepare a petition for modification of child support and complete the mandatory Georgia child support worksheet plus a domestic relations financial affidavit. Use the official calculator at csc.georgiacourts.gov to estimate the guideline amount.
File in the correct Superior Court
Promptly after the change days after startingFile your petition in the Superior Court of the county where the other parent resides and pay the filing fee, or request a fee waiver if you cannot afford it. A petition for modification follows the same rules as an original support action (O.C.G.A. 19-6-15(k)(4)).
Serve the other parent
Right after filing days after startingHave the other parent served with your filed petition and file proof of service. For a 25 percent involuntary income loss, the support attributable to lost income stops accruing from the date of service, so serve promptly (O.C.G.A. 19-6-15(j)).
Consider a DCSS review or attend your hearing

Frequently Asked Questions
A genuine, involuntary income loss can support a modification, and if the loss is 25 percent or more, the support attributable to that lost income does not accrue from the date the other parent is served (O.C.G.A. 19-6-15(j)). You must still file to change the amount, and you should not simply stop paying.
No. Either parent can file a petition for modification on their own, and the other parent is served and can respond. If both parents agree on a new amount, they can present a consent agreement with a completed child support worksheet for the court to review and approve under the guideline (O.C.G.A. 19-6-15).
After you file in Superior Court, the case follows the same procedure as an original support action, so timing depends on the county's docket and whether the other parent contests it (O.C.G.A. 19-6-15(k)(4)). A Division of Child Support Services review is free but can take longer. File and serve promptly.
If DCSS manages your case, you can ask it to review the order at no charge. The agency gathers both parents' financial information, checks for a substantial change, and can seek a new order through the court if a modification is warranted. DCSS does not act as your private attorney in the case.
You can seek a modification whenever there is a substantial change in circumstances, but you generally cannot refile within two years of a prior modification order unless an exception applies (O.C.G.A. 19-6-15(k)(2)). If DCSS handles your case, you can request a review about every three years under federal rules.
A modification generally changes support only going forward, so amounts that already came due, called arrears, are not erased. Even for a 25 percent involuntary income loss, the protection only stops the affected support from accruing after the date of service (O.C.G.A. 19-6-15(j)). Keep paying to avoid building arrears.
You file a petition for modification in the Superior Court of the county where the other parent resides, attaching the mandatory Georgia child support worksheet and a domestic relations financial affidavit. Georgia has no single statewide modification form, so check your Superior Court clerk's local requirements before filing (O.C.G.A. 19-6-15(k)(4)).
Usually yes. You generally cannot file a new modification within two years of the final order on your previous modification petition, unless the other parent failed to exercise ordered visitation, exercised more visitation than ordered, or you had an involuntary loss of income (O.C.G.A. 19-6-15(k)(2)).
