Arizona Spousal Maintenance: New Guidelines Effective Sept. 1, 2025

In Arizona family law, spousal maintenance (often called alimony) is financial support one spouse may pay another after divorce to help the receiving spouse become financially self-sufficient.

Arizona law has long recognized that some divorcing spouses need transitional support, but until recently, there were no clear, statewide guidelines dictating how much maintenance courts should award and for how long.

Effective September 1, 2025, the Arizona Supreme Court adopted significant revisions to the Arizona Spousal Maintenance Guidelines.

These revised guidelines now apply statewide to all spousal maintenance orders entered on or after that date, whether in original divorce orders or modifications, except when the parties agree otherwise. 

These changes were introduced in response to extensive review by courts and legal professionals and aimed to provide greater consistency, fairness, and predictability in spousal maintenance outcomes. Ideally, the goal is to help both parties understand the likely range of support amounts and durations.

What Spousal Maintenance Is and Why It Matters

Spousal maintenance in Arizona is not automatic. A court first determines eligibility under Arizona Revised Statutes Sections 25-319(A). 

Maintenance exists to help a spouse who:

• Lacks sufficient property/space to meet reasonable needs
• Is unable to support themselves through employment
• Has contributed to the other spouse’s career or reduced their own income capacity (through availability, and also often in education)
• Is the parent of a child whose needs make employment impractical
• Has been in a long-term marriage
• One whose age or condition makes self-sufficiency difficult 

The overall purpose is rehabilitative, meaning spousal maintenance is typically designed in a way that helps the recipient transition into self-support, not to provide lifetime dependency. 

What Changed on September 1, 2025

The 2025 revisions to Arizona’s Spousal Maintenance Guidelines include several significant structural and calculation changes that affect how courts determine both the amount and duration of maintenance.

These guidelines are intended to serve as a framework for judges’ decision-making. 

1. Eligibility Must Be Determined First

Under the updated process, courts must first find that a spouse is eligible for spousal maintenance before applying the guidelines. This change clarifies that eligibility is separate from the calculation and that the guidelines should not be used mechanically without this threshold determination.

2. Changes to Income and Asset Treatment

The 2025 revisions refine how income and assets are considered:

• Mortgage principal payments are no longer included in income calculations (removing a factor that previously often inflated guideline ranges)
• Income-producing properties are assessed equitably (not on a presumed blanket rate of return calculation) 
• Retirement accounts and Social Security income are attributed only under specific conditions (such as “after eligible retirement age”)
• Courts can now average overtime income over three years 

These changes often result in lower guideline amounts. This seems to be particularly prevalent in households with significant mortgage obligations or much higher incomes. 

3. Duration Adjustments

Duration ranges have been revised to reflect the impact of marriage length better:

For marriages of 16 years or more (192+ months) not covered by the “Rule of 65” (which combines age and marriage length for discretionary duration), the maximum guideline duration has increased from 8 years to 12 years or up to 50% of the marriage length, whichever is greater.

Shorter marriages better align with reasonable transition periods. 

These changes in duration help courts tailor support periods to the realities of long-term economic interdependence in extended marriages.

4. Updated Spousal Maintenance Calculator

Concurrent with the new Guidelines, Arizona’s updated Spousal Maintenance Calculator went into effect on September 1, 2025. This tool helps provide a range of amounts and durations based on data like combined family expenditures and income shares.

However, both parties and courts should view the calculator as a guide, not a strict formula. Judges retain discretion to tailor awards that deviate from the calculator, with supporting written documentation of the findings. 

The new calculator reflects the updated Guidelines, including how income is counted, how family size is defined, and how exceptional factors may be incorporated.

What These Changes Mean for You

Here are a few ways these changes could affect you.

Greater Predictability

The 2025 Guidelines give more precise indications of likely spousal maintenance amounts and durations. This has gone a long way toward helping parties, during mediation, negotiation, or even trial, set realistic expectations.

Fairer Assessments

By removing distortions such as mortgage principal inclusion, refining income attribution, and updating duration formulas, the guidelines aim to ensure awards reflect actual financial needs and abilities. 

Judicial Flexibility

Although the guidelines provide ranges, courts may disagree and set awards outside those parameters. When they do, judges are required to provide specific written findings explaining why a deviation is appropriate. 

When the Guidelines Apply

The revised Guidelines and calculator apply to all spousal maintenance orders entered on or after September 1, 2025, including new orders and modifications, unless otherwise agreed by the parties.

When it comes to default cases involving orders before this date, the rules generally do not apply. 

Practical Tips for Arizona Spouses

These tips may help:

• Confirm the eligibility factors first. Before even thinking about amount or duration, confirm whether maintenance is actually warranted under A.R.S. Sections 25-319(A). 
• Use the updated calculator. Always run maintenance figures through the 2025 tool, being careful not to use older versions that may still be present on old site pages, blogs, and websites. 
• Prepare documentation. Gather all information related to your income history, job prospects, and property information.
• Consider negotiation or mediation. You can certainly agree on terms that deviate from the guidelines if you wish.
• Understand duration ranges. Long-term marriages may justify more extended maintenance periods under the updated rules.

The Bottom Line

Arizona’s revised Spousal Maintenance Guidelines, effective September 1, 2025, represent an essential evolution in family law. The guidelines bring clarity and structure to a process that was once highly unpredictable, focusing support on rehabilitative needs and self-sufficiency.

Parties navigating divorce or modification proceedings in Arizona should educate themselves about these changes, use the updated calculator appropriately, and consider skilled legal guidance to protect their rights and financial futures.
