Coconino County, Arizona Child
Support Estimator

Arizona child support is calculated under statewide Income Shares guidelines, but the filing, review, and enforcement process is local. Parents in Coconino County use the same statewide formula as the rest of Arizona, then work through the county family court or child support agency process for orders, modifications, and enforcement.

Coconino County ranks 7th by population among 15 Arizona counties. That matters for scheduling, clerk procedures, local forms, and how quickly a support order or modification moves through the court calendar.

The core inputs are each parent's income, the number of children, health insurance premiums, work-related child care, existing support obligations, and parenting time. Arizona's calculator model is Income Shares.

Governing authority: A.R.S. § 25-320; Arizona Child Support Guidelines.

County location does not usually change the statewide formula, but it does determine where parents file, which clerk reviews paperwork, and which local judge or hearing officer applies the guidelines. Income Shares model using both parents' combined adjusted gross income under Arizona Supreme Court Rule 9(D) and the Arizona Child Support Guidelines Schedule of Basic Support Obligations.

Combined income up to approximately $20,000/month is fully scheduled; above that threshold, the court has discretion. Parenting time credit reduces the obligation when the non-custodial parent has 25%+ parenting time.

Administered by the Arizona Department of Economic Security (DES) Division of Child Support Services (DCSS). Statute: A.R.S. § 25-320 and the guidelines promulgated thereunder.

Run the calculator with monthly or weekly income figures that match the official Arizona worksheet. If a parent is self-employed, unemployed, or paid irregularly, gather tax returns, pay stubs, and proof of benefits before relying on the estimate.

Parenting time can affect child support because many states adjust the payment when the paying parent has substantial overnights. Enter the actual schedule, not the schedule you expect to negotiate later.

Parents in Coconino County should keep a written parenting-time calendar, school schedule, holiday rotation, and transportation plan. Those documents help the court compare the calculator estimate with the real custody arrangement.

If custody is still disputed, treat the estimate as a planning number. A final Arizona child support order can change once the court sets income findings, parenting time, insurance credits, and child care allocations.

A child support estimate is not a court order. To change an existing order, a parent usually must file a modification request and show a qualifying change in income, custody, health insurance, child care costs, or another guideline factor.

For enforcement, Arizona may use income withholding, payment records, tax refund interception, license actions, or contempt proceedings depending on the facts and the agency or court handling the case.

Before filing in Coconino County, compare your calculator result with the current order and collect proof for each input. Courts generally need documents, not estimates alone, before changing a support obligation.

Child support often intersects with custody, alimony, property division, and divorce costs. Use the Arizona Custody Time Calculator to model overnights, then compare support with the Arizona Alimony Calculator and Arizona Divorce Cost Estimator.
