Arizona Spousal Maintenance Guidelines 2025

What Changed in September 2025

Arizona overhauled its spousal maintenance guidelines effective September 1, 2025, under Administrative Order No. 2025-101. The revisions replaced open-ended judicial discretion with a formula-driven calculator that produces presumptive ranges for both the monthly amount and duration of support.

The Two-Step Process Courts Must Follow

Arizona courts can't skip straight to the calculator. Spousal maintenance requires a strict two-step analysis:

Step 1: Threshold eligibility. The requesting spouse must qualify under at least one ground in A.R.S. § 25-319(A). The court must make a formal finding — you can't establish eligibility by simply running the numbers. The five grounds are:

1. You lack sufficient property (including your share of community property) to meet reasonable needs
2. You can't become self-sufficient through appropriate employment
3. You're the custodian of a child whose age or condition prevents employment outside the home
4. You contributed significantly to your spouse's education, training, or career advancement
5. The marriage was long and your age may prevent gaining adequate employment

Step 2: Guidelines calculation. Once eligibility is established, the court uses the official Arizona Spousal Maintenance Calculator to generate a presumptive monthly range and duration range. These are presumptive ranges, not automatic awards.

Three Key Changes Under AO 2025-101

Mortgage principal is excluded. The previous 2023 guidelines added the family's monthly mortgage principal payment to the calculator inputs, which inflated support ranges — sometimes significantly. The September 2025 revision removed mortgage principal entirely. This simplifies the disclosure process and generally lowers calculated support amounts.

Higher threshold for high-income adjustments. The income level triggering the high-income adjustment jumped from $100,000 to $175,000 of annual intact family income. At the same time, the maximum upward adjustment dropped from 80% to 70%. For higher-earning households, this means lower presumptive maintenance.

Longer maximum duration for long marriages. For marriages of 16+ years that don't qualify under the Rule of 65, the maximum presumptive duration increased from 8 years (96 months) to 12 years (144 months) or 50% of the marriage length — whichever is greater. This better accounts for the financial dependence that builds over decades.

Duration Ranges by Marriage Length

The Rule of 65

The Rule of 65 isn't a separate type of support — it's a mechanism that unlocks greater judicial discretion over duration. When all three criteria are met, the court can award extended or even indefinite maintenance:

1. The requesting spouse is at least 42 years old
2. The marriage lasted at least 16 years (192 months)
3. The spouse's age plus the marriage length equals or exceeds 65

A 48-year-old after an 18-year marriage qualifies (48 + 18 = 66 ≥ 65). A 40-year-old after a 20-year marriage does not (40 + 20 = 60 < 65).

What Doesn't Matter

Marital misconduct. Under A.R.S. § 25-319(C), the court cannot consider infidelity or other fault-based behavior when calculating spousal maintenance. Arizona maintenance is rehabilitative — designed to help the lower-earning spouse become self-sufficient, not to punish the other.

Termination and Modification

Spousal maintenance automatically ends upon the death of either party or the remarriage of the recipient — unless otherwise agreed in writing. Cohabitation with a romantic partner doesn't trigger automatic termination, though it can support a modification request based on changed financial circumstances.

Spouses can agree in writing to make their maintenance terms non-modifiable under A.R.S. § 25-319(D). This locks in both amount and duration, preventing either party from going back to court later.

Tax Treatment

For divorces finalized after December 31, 2018, spousal maintenance is not tax-deductible for the payer and not taxable income for the recipient. The payer makes payments with after-tax dollars, which increases the real cost of support. Factor this into your settlement negotiations.

Calculating Your Range

The Arizona Divorce Financial Split Guide includes a spousal maintenance pre-calculator aligned with the September 2025 guidelines, so you can estimate your range before your first meeting with a mediator or attorney.
