Child Support in Alabama
Alabama calculates child support using the income shares model. It is set out in Rule 32 of the Alabama Rules of Judicial Administration. The model combines both parents' gross incomes. It applies a schedule of basic support obligations tied to the number of children. The combined amount is then divided between the parents in proportion to their income. A parent seeking a new order works from the Form CS-42 worksheet. The Alabama court system publishes this worksheet as part of Rule 32. Most Alabama child support cases move through circuit court. This holds whether the case begins as part of a divorce, a paternity action, or a standalone petition. Parents who want help can apply through the Alabama Department of Human Resources Child Support Enforcement Division. This is the state's IV-D agency, and it represents the state in these cases.

The income shares model under Rule 32
Alabama's guidelines assume a child should receive the same share of parental income they would have received if the parents lived together. Rule 32 sets a schedule of basic support obligations by combined income and number of children. It then splits that amount between the parents based on each parent's share of the combined income. The paying parent's share becomes the presumptive support amount. This is subject to adjustments for health insurance and work-related child care, both of which Rule 32 lists. Every case uses a Form CS-42 worksheet and a Form CS-41 income statement or affidavit. Rule 32 requires either a completed CS-42 or a CS-43 Notice of Compliance before a support order is entered.
Applying for services through DHR
The Alabama Department of Human Resources Child Support Enforcement Division is the state's IV-D agency. It runs the federally required child support program. A parent can apply for services online through DHR or at a county DHR office. The division can help establish paternity, set up a new order, or collect on one that already exists. Parents already receiving certain public assistance are enrolled automatically. Anyone else applies directly through DHR's own process.
Who hears an Alabama child support case
Circuit courts handle Alabama child support actions. This is true whether the request arises inside a divorce case, a paternity case, or a standalone petition. The domestic relations division of the circuit court applies the Rule 32 guidelines to the parents' verified income statements. This produces the presumptive obligation. DHR's Child Support Enforcement Division can ask the court to establish or enforce an order. It can also pursue certain enforcement steps on its own, but the support amount itself is set under the court's Rule 32 calculation.
Modifying an existing order
Rule 32 sets the standard for changing an Alabama child support order. A rebuttable presumption of a material change applies when recalculating the guidelines produces an amount that differs from the existing order by more than ten percent. This does not apply if the existing order was itself the product of a rebuttal of the guidelines with no change since. A court can also grant a modification without that ten percent variation. This requires the parent asking for the change to prove a substantial and continuing change in circumstances. A court can likewise deny a modification even where the gap exists, if applying the guidelines would be unjust.
Enforcement tools
Alabama's Child Support Enforcement Division can pursue several tools once a parent falls behind. These include income withholding directly from a paycheck, interception of state and federal tax refunds, and suspension of a driver's or professional license. The division can also report the debt to credit bureaus. A parent who does not comply with an order can be held in contempt of court. These tools apply whether DHR opened the case originally or a parent applied for enforcement-only help after getting a court order on their own.

Child Support in Alabama: frequently asked questions
Does Alabama use the income shares model for child support?+
Yes. Alabama Rule of Judicial Administration 32 bases child support on the income shares model.

What court handles child support cases in Alabama?+

When can I get my Alabama child support order modified?+
Rule 32 creates a rebuttable presumption of a material change when recalculating the guidelines produces a support amount more than ten percent different from the existing order. A court can also modify without that gap if you prove a substantial and continuing change in circumstances. It can decline to modify even with the gap if applying the guidelines would be unjust.
