How is Child Support Calculated in Alabama?

To estimate your child support, Alabama combines your and the other parent's gross monthly incomes. This total is used to find a basic support amount on a state schedule, as required by Alabama Rules of Judicial Administration, Rule 32. Your final share is then based on your percentage of the combined income, plus adjustments for costs like health insurance and childcare.

Understanding Alabama's Shared Custody Rules

In Alabama, when a parent has physical custody for 146 or more overnights per year, a different shared parenting formula is used. Under Alabama Rules of Judicial Administration, Rule 32, the basic support obligation is first increased by 50%. A cross-credit calculation is then applied based on the number of overnights each parent has to determine the final amount, which often reduces the payment.

Frequently Asked Questions About AL Child Support


At what age does child support end in AL?

Child support in Alabama automatically ends when the child reaches the age of 19. Under Alabama Code § 26-1-1, 19 is the state's age of majority, and unlike many states, there is no automatic exception for a child still attending high school.

How is child support calculated if one parent is unemployed in AL?

The court will impute (assign) income to an unemployed parent if it finds the parent is voluntarily jobless or earning less than their capacity. This imputed income is based on factors like the parent's recent work history, education, and local job opportunities, as outlined in Rule 32(B)(5) of the Alabama Rules of Judicial Administration.

How do I modify a child support order in AL?

You can modify a child support order in Alabama if there is a material change in circumstances, which is presumed to exist if a new calculation shows a change of more than 10% from the existing order. This standard is established by Rule 32(A)(3)(b) of the Alabama Rules of Judicial Administration.

Does AL child support cover college expenses?

Alabama courts can order a parent to pay for post-secondary college expenses, but it is not mandatory or automatic. A judge may order post-minority support for college upon a parent's request if certain conditions are met, a unique provision within Rule 32 of the Alabama Rules of Judicial Administration.

How does AL handle health insurance and childcare costs?

Health insurance premiums and reasonable work-related childcare costs are added to the basic child support obligation and divided between the parents in proportion to their incomes. The parent who directly pays these expenses receives a credit against their total support obligation, as detailed in Rule 32(B)(7) of the Alabama Rules of Judicial Administration.
