Understanding Alabama Child Support Guidelines (Rule 32)

Alabama's child support guidelines follow the "Income Shares Model," which is based on the concept that children should receive the same proportion of parental income that they would have received if the parents lived together.

Alabama's Calculation Process
  1. Determine gross income of both parents
  2. Adjust for preexisting child support obligations
  3. Calculate combined adjusted income and determine the basic support obligation from the Alabama schedule
  4. Add childcare and health insurance costs to get the total child support obligation
  5. Prorate the obligation between parents based on their proportionate share of income
  6. Calculate the support payment by the non-custodial parent
Joint Custody Adjustments

In joint physical custody situations, Alabama may adjust the support amount based on the number of days the child spends with each parent. When a child spends significant time with both parents, the courts may adjust the support calculation to account for the increased costs to the non-custodial parent.

Deviations from Guidelines

Courts may deviate from the standard calculation when:

  • The parents agree to a different amount that serves the best interest of the child
  • There are extraordinary medical, educational, or other expenses
  • The parents have significant shared custody arrangements
  • A parent has extraordinary expenses (e.g., high travel costs for visitation)
  • The child receives substantial income
\[ \text{Monthly Support} = \max\Bigl(0,\; \underbrace{O \times \frac{I_{\text{nc}}}{I_{c} + I_{\text{nc}}}}_{\text{Basic Share}} + A_{H} + A_{D} + A_{C} + A_{M} + A_{E} + A_{J} \Bigr) \] where:
  • \(O\) = Basic obligation from Alabama Rule 32 schedule
  • \(I_{c}, I_{\text{nc}}\) = Adjusted incomes of custodial and non-custodial parents
  • \(A_{H}, A_{D}, A_{C}, A_{M}, A_{E}, A_{J}\) = Adjustments for Health, dental, childcare, medical, education, and custody time
