Arizona spousal maintenance guidelines
How Arizona sets the standard spousal maintenance duration range.
The Arizona Supreme Court's 2025 Spousal Maintenance Guidelines took effect September 1, 2025. The guidelines provide standard duration ranges after a spouse has been found eligible for maintenance. For marriages under 24 months, the standard range is 3–12 months; 24 to under 60 months, 6–36 months; 60 to under 120 months, 6–48 months; 120 to under 192 months, 12–60 months; and 192 months or more, 12 months up to 144 months or 50% of the marriage length, whichever is greater, unless the Rule of 65 applies. [2][3]
Arizona duration depends on marriage length, age, and specified exceptions.
The Rule of 65 applies when the spouse seeking maintenance is at least 42 years old, the marriage lasted at least 16 years, and that spouse's age plus the marriage length is at least 65. When it applies, duration is within the court's discretion rather than a standard fixed range. [3]
Arizona maintenance amount
Why this page sends amount calculations to Arizona's official calculator.
Arizona's official amount calculator uses Spousal Maintenance Income, family size, expenditure data, attributed income, and a high-income adjustment. The 2025 Guidelines say the calculator uses Consumer Expenditure Survey data and adds a high-income adjustment beginning at $175,000 of intact-family annual income. Rather than reproduce that data model without an official parity test, AlimonyCalculator.org directs users to the court's statewide calculator for the amount range. [2][3][4]
Questions about Arizona alimony calculations.
Does the Arizona duration range prove that a spouse will receive maintenance?
No. A.R.S. §25-319(A) contains the eligibility rules. The 2025 Guidelines explain that a spouse cannot use the calculator range to prove eligibility. The court first determines eligibility, then applies the guidelines if appropriate. [1][3]
What is the Arizona Rule of 65?
The Rule of 65 is a duration rule. It requires the requesting spouse to be at least 42 years old, the marriage to be at least 16 years, and age plus marriage length to equal or exceed 65. If all three conditions are met, duration is determined case by case. [3]
Why doesn't this site copy Arizona's official amount calculator?
The official calculator uses economic expenditure data and guideline adjustments beyond a simple statutory percentage. Until an independent implementation can be tested against the official calculator, this site uses the official court tool for amount calculations instead of presenting an unverified duplicate.
