Inputs you need for Alimony Child Support in Arizona

Inputs you will need

Run this scenario in DocketMath using the Alimony Child Support calculator.

If you’re using DocketMath’s “alimony-child-support” calculator for Arizona (US-AZ), start by gathering the details that control the math. In real cases, outcomes can pivot on things like income timing, parenting time, and which costs are included—so the goal of this input-checklist is to help you avoid missing a required field or relying on rough guesses.

Below is a practical input-checklist you can use before you click Run it.

Personal and case context

Income inputs (use current or most recent figures available)

Pitfall to avoid: If you use “annual income ÷ 12” from an old pay stub, your estimate can drift. Even one changed number—like commissions stopping or overtime decreasing—can move both child support and any alimony-related estimate.

Child-related inputs

Support affecting circumstances (only include what you can document)

Alimony-specific inputs

Where to find each input

Collecting the right numbers usually takes less time than people expect—if you know where to look first.

Most inputs live in the case file, contracts, or docket entries. Dates usually come from the triggering event notice; rates and caps come from governing documents or statute; and amounts come from the ledger or judgment. Record the source for each value so the run is reproducible.

Income

  • Pay stubs (most current): gross pay, overtime, commissions, recurring bonuses
  • Employer letters / HR statements (useful when pay stubs don’t show the full income pattern)
  • Tax returns (good for a baseline if pay stubs are inconsistent year-to-year)

Practical tip: If income changes seasonally, use the most recent 2–3 months to estimate the current monthly average, and keep a note of which months you used.

Parenting time / custody schedule

  • Proposed or existing custody agreement (drafts count if they’re consistent)
  • A calendar-based pattern (week-by-week routine)
  • Any court orders (if they exist—use the operational schedule, not just labels like “50/50”)

If your schedule changes from month to month, build a representative month you can apply consistently.

Childcare, health insurance, medical costs

  • Invoices and receipts for childcare
  • Insurance premium statements (monthly)
  • Recurring medical bills (you can often summarize typical monthly amounts if the tool expects a monthly figure)

Marital duration and key dates

  • Marriage date and separation date from your records
  • If you’re unsure, choose the best-documented date you have and update it later once you confirm it

Run it

Once your inputs are ready, use DocketMath:

  1. Open the calculator: ** /tools/alimony-child-support
  2. Enter the inputs in the requested fields.
  3. Review the outputs for both:
    • Child support estimate, driven primarily by:
      • number of children,
      • monthly income amounts,
      • and parenting time (often one of the biggest schedule drivers)
    • Alimony estimate, driven primarily by:
      • income differences,
      • marital duration,
      • and the time/earning-capacity factors the tool requests

How outputs change when inputs change

Use these quick checks to see whether results “move” in a way that matches your expectations:

  • If you increase one party’s monthly gross income:
    • Expect child support to generally increase for the payor-side direction.
    • Alimony-related estimates may also shift because income disparity changes.
  • If you change parenting time (for example, more time with the other parent):
    • Expect the child support estimate to change, because the schedule affects how support is allocated.
  • If you add or remove childcare or health insurance/medical inputs:
    • Expect the estimate to increase if those categories are included.

Timing note (SOL) — separate from the calculator

Arizona’s general/default statute of limitations is 2 years under A.R.S. § 13-107(A). The statute cited here concerns general limitations in the context referenced by that law, and no claim-type-specific sub-rule was identified in the materials used for this brief.

Note: The 2-year general SOL under A.R.S. § 13-107(A) is a default rule for general limitations, not a family-law-specific deadline for support. Family-law timing and enforcement rules can differ, so if you’re dealing with deadlines or enforcement of older events, confirm the applicable rules for your exact situation.

(As a reminder: this is general guidance, not legal advice.)
