Alabama Child Support Overview

Alabama uses the income shares model for calculating child support. This model is based on the principle that children should receive the same proportion of parental income they would have received if the family were intact. Both parents’ incomes are combined, and the support obligation is divided proportionally.

Alabama uses Rule 32 of the Alabama Rules of Judicial Administration. Both parents’ adjusted gross monthly incomes are combined and applied to the Schedule of Basic Child-Support Obligations, which estimates the cost of raising children at that income level for 1 through 6 children. Each parent’s share is determined proportionally based on their percentage of the combined income. The schedule covers combined income from 0 to 20000 per month. A self-support reserve of 981 per month protects low-income obligors from falling below the poverty threshold. If the calculated obligation is less than 50, there is a rebuttable presumption that a 50 minimum should be ordered. For obligors with no gross income receiving only means-tested assistance, a zero-dollar order is presumed. For shared physical custody (approximately 50/50), a 150 percent multiplier is applied to the basic obligation using Form CS-42-S (effective June 1, 2023).

How Alabama Calculates Child Support

The Alabama child support calculation considers multiple factors:

1. Determine each parent’s gross income — wages, salary, commissions, bonuses, self-employment income, investment income, and other sources.
2. Calculate combined parental income — add both parents’ adjusted gross incomes together.
3. Apply the guideline schedule — Alabama’s guidelines provide a base support amount based on combined income and number of children.
4. Prorate between parents — each parent’s share is proportional to their percentage of the combined income.
5. Add healthcare and childcare costs — these are added to the base amount and divided proportionally.
6. Apply adjustments — parenting time credits, other child obligations, and special circumstances may adjust the final amount.

What Counts as Income in Alabama

Gross income. Includes salary, wages, bonuses, commissions, severance pay, workers compensation benefits, pensions, unemployment compensation, disability benefits, Social Security benefits, self-employment income, rent, royalties, dividends, interest, capital gains, and any other income. Rule 32 then calculates Income Available for Support as 85 percent of the adjusted gross income after certain deductions (preexisting child support obligations, other children in the home).

Imputed income: YES. If a parent is found to be voluntarily unemployed or underemployed, the court shall estimate the income that parent would otherwise have and impute that income. Factors considered include the parent’s assets, residence, employment and earnings history, job skills, educational attainment, literacy, age, health, criminal record and other employment barriers, record of seeking work, the local job market, availability of employers, and prevailing earnings in the local community. Exception: the court may consider the presence of a young child or a physically or mentally disabled child necessitating the parent to remain in the home.

Deviation factors: Shared physical custody or visitation substantially in excess of customary arrangements; extraordinary costs of transportation for visitation; expenses of college education incurred before the child reaches age of majority; assets of or unearned income received by or on behalf of a child; special needs of the child including physical or mental disabilities; actual childcare costs exceeding the allowed amount by at least 20 percent; and any other relevant factor the court finds justifies deviation from the guidelines. The existence of one or more reasons does not require deviation, and the court may deviate even without an enumerated reason if evidence supports it.

Healthcare & Childcare in Alabama Child Support

Health insurance: The cost of health insurance for the child is added to the basic child support obligation and divided between parents in proportion to their adjusted gross incomes. The health insurance cost is calculated as the pro rata portion of the premium directly attributable to the child — total premium divided by the number of persons covered, multiplied by the number of children in the order. Uninsured medical expenses are typically split proportionally between parents. Courts may order the parent with access to more affordable coverage to maintain insurance.

Childcare costs: Work-related childcare costs for children under age 12 resulting from employment or job search activities are added to the basic child support obligation and divided proportionally between parents. Rule 32 limits allowable childcare costs based on a schedule developed by the Alabama Department of Human Resources. If actual childcare costs exceed the allowed amount by at least 20 percent, the court may deviate from the guidelines to account for the higher costs.

When Does Alabama Child Support End?

In Alabama, child support generally ends when the child reaches 19. Alabama’s age of majority is 19. Child support terminates when the child turns 19 or is otherwise emancipated through marriage, military service, or court order. Exception: support does not terminate at 19 if the child is unable to care for themselves due to a physical or mental disability.. However, support may continue or end earlier based on:

• The child graduates from high school (if still a minor)
• The child becomes emancipated (marriage, military service, self-supporting)
• The child has special needs requiring ongoing support
• College support: NO. Alabama courts no longer have authority to order parents to pay post-minority college or educational expenses for children over 19. This changed after the Alabama Supreme Court’s 2013 ruling in Ex parte Christopher, which eliminated court-ordered post-minority educational support. Any college support must be voluntarily agreed upon by the parents, typically as part of a divorce settlement. Courts may consider pre-majority college expenses (before age 19) as a deviation factor.

Modifying Alabama Child Support

When to modify: A 10 percent or more difference between the existing child support order and the amount that would result from applying the current guidelines creates a rebuttable presumption that modification is appropriate. However, the court retains discretion to modify even when the difference is less than 10 percent if a material change in circumstances is shown. The change must be substantial and continuing (not temporary). Common triggers include significant changes in either parent’s income, job loss, disability, changes in custody arrangements, changes in the child’s needs, or changes in healthcare or childcare costs.

How to modify: Either parent may file a petition to modify child support with the circuit court that issued the original order. Alternatively, parents receiving IV-D services through the Alabama Department of Human Resources Child Support Enforcement Division may request a periodic review and adjustment of their child support order through DHR. DHR reviews orders every three years or upon request when a substantial change in circumstances is alleged. The petition must plead and prove a material change in circumstances that is substantial and continuing since the last order.

Either parent can request a modification. Changes are typically not retroactive to before the date of filing the modification request.

Alabama Child Support Enforcement

Alabama has multiple tools to enforce child support orders when a parent fails to pay:

• Income withholding/wage garnishment (up to 65 percent of disposable income); federal and state tax refund intercept (minimum 150 owed for TANF cases or 500 for non-TANF cases); driver’s license suspension; professional license suspension; sporting and recreational license suspension; contempt of court (fines and jail time); property liens; bank account seizure; credit bureau reporting of arrears; passport denial (for arrears of 2500 or more); unemployment benefit intercept. DHR follows a structured enforcement timeline with initial notice of delinquency after 30 days
• income withholding within 14 days of notice
• and license suspension warnings after 60 days.

Additional Alabama rules: Self-support reserve (SSR) of 981 per month ensures paying parents retain enough income for basic necessities, updated to reflect 2021 federal poverty levels adjusted for Alabama incomes. Shared custody threshold uses a 150 percent multiplier applied to the basic obligation with separate worksheet Form CS-42-S (effective June 1, 2023). Alabama charges 12 percent annual interest on child support arrears. The Income Available for Support calculation uses 85 percent of adjusted gross income. All IV-D payments are processed through the Alabama Location Enforcement Collection System (ALECS). Payments can be made via ExpertPay or MoneyGram.
