Child Support in Montgomery County, Alabama: How Much Will You Owe?

Quick answer: it depends on both parents' incomes, how many children you have, and the parenting schedule. The calculator on this page turns those numbers into a real guideline estimate in about a minute. It is an educational estimate, not legal advice, and the judge always sets the final amount. FamilyCourtHelp.com is a self-help resource, not a law firm.

How much child support will you owe in Montgomery County, Alabama? There is no flat rate. Alabama uses one statewide formula, and the number moves with each parent's income, the number of children, and how many overnights the kids spend with each of you. This page walks through how the math works, and you can run your own estimate right here.

Alabama follows the Income Shares model under Rule 32 of the Alabama Rules of Judicial Administration. The court combines both parents' monthly gross incomes, looks up the basic support obligation on the state's guideline schedule for that income level and number of children, then prorates the obligation between the parents according to each parent's percentage share of the combined income.

What counts as income? Alabama runs the formula on gross income, meaning income before taxes come out. Income includes wages, salary, commissions, bonuses, self-employment net earnings, rental income, pensions, unemployment, workers' compensation, Social Security, and other recurring sources. Means-tested public assistance such as TANF, SNAP, and SSI is excluded. Reasonable business expenses can be deducted from self-employment income.

Parenting time matters in Alabama, but not as an automatic formula: the judge can adjust the guideline number when one parent has substantial time with the children. Alabama uses the Income Shares model, and ordinary parenting time is not built into the basic schedule as an automatic per-overnight credit: extended visitation beyond the standard schedule is a deviation factor a judge may consider under Rule 32. That is not the whole picture. Rule 32(C)(7), adopted in 2023 with form CS-42-S, sets out a separate method for cases where the parents share physical custody roughly equally, so equal shared custody is handled by that method rather than only as a deviation (Rule 32: https://judicial.alabama.gov/docs/library/rules/ja32.pdf). The on-page calculator gives an estimate only and does not run the CS-42-S shared-custody math, so confirm any parenting-time adjustment with the official worksheet or an attorney.

When does it end? Support generally runs until the child reaches age 19, Alabama's age of majority under Ala. Code § 26-1-1. Alabama does not add an automatic extension to high-school graduation after 19: Ex parte Christopher, 145 So. 3d 60 (Ala. 2013), ended court-ordered post-minority educational support, while leaving already-final orders entered before that decision undisturbed. A court may still order support for a person who cannot support themselves because of a disability that arose during minority (Ex parte Brewington, 445 So. 2d 294 (Ala. 1983); Martin v. Martin, 494 So. 2d 97 (Ala. Civ. App. 1986)), which is not automatic for every disability. An enforceable agreement between the parents can also extend support. Death, marriage, or emancipation of the child ends the obligation earlier, and any arrears already accrued remain owed.

Can the amount change later? Either parent can petition the court that issued the order, or request administrative review through DHR Child Support Services. Under Rule 32(A)(3)(c) of the current Rule 32 (preface effective June 1, 2023) a variance of MORE THAN 10% between the existing order and a new guideline calculation is rebuttably presumed to be a material change of circumstances; the presumption does not apply when the variance results from the guideline rebuttal applied in the existing order AND the circumstances that caused that rebuttal have not changed, and Rule 32(A)(3)(e) preserves the court's discretion.

If payments fall behind, Alabama has real enforcement tools. Wage withholding is automatic on every new Alabama order. Additional remedies include tax refund interception, license suspension, contempt of court with possible incarceration, liens on real and personal property, and reporting to credit bureaus.

Frequently asked questions

How much child support will I owe in Montgomery County, Alabama?

There is no flat amount. Alabama uses the Income Shares model under Ala. R. Jud. Admin. Rule 32, so the number depends on both parents' incomes, the number of children, and the parenting schedule. The calculator on this page gives you a guideline estimate in about a minute, and the court sets the final amount.

Does parenting time change child support in Alabama?

Parenting time matters in Alabama, but not as an automatic formula: the judge can adjust the guideline number when one parent has substantial time with the children. Keep a clear record of your actual schedule, because the overnight count is one of the main inputs.

When does child support end in Alabama?

Generally age 19 in Alabama, the age of majority under Ala. Code § 26-1-1. There is no automatic extension to high-school graduation past 19. A court may order continued support for a person who is unable to support themselves because of a disability that arose during minority, which is not automatic in every disability case, and an enforceable agreement between the parents or a preserved older educational-support order can change the result in an individual case.

Can the child support amount be changed later in Alabama?

Usually yes, when circumstances change enough. Ala. R. Jud. Admin. 32(A)(3)(c): a new guideline calculation that varies MORE THAN 10% from the existing order is rebuttably presumed to be a material change of circumstances. Exactly 10% is not enough, the presumption does not apply where the variance is due to the court's application of the guideline rebuttal in the existing order AND there has been no change in the circumstances that caused that rebuttal, and Rule 32(A)(3)(e) leaves the court discretion to modify outside that threshold.
