Arizona spousal maintenance (the state's legal term for alimony) typically lasts between 30% and 50% of the marriage's duration, with a maximum cap of 12 years for marriages lasting 16 years or more. Under revised Arizona Spousal Maintenance Guidelines effective September 1, 2025, courts follow a formula-based approach to determine both the amount and duration of support. For a 10-year marriage, expect 3 to 5 years of maintenance; for a 20-year marriage, the duration may reach 10 years or more. Remarriage of the recipient automatically terminates the obligation under A.R.S. 25-327.

How Arizona Courts Determine Alimony Duration
Arizona courts determine how long alimony lasts by applying the Spousal Maintenance Guidelines approved by the Arizona Supreme Court, most recently revised effective September 1, 2025. The base duration formula awards maintenance for 30% to 50% of the marriage's total length in months. A marriage lasting 120 months (10 years) produces a guideline duration range of 36 to 60 months (3 to 5 years). Courts do not have authority to deviate from these duration ranges under A.R.S. 25-319, making the formula effectively binding.
The duration calculation begins with the total months of marriage, measured from the date of marriage to the date of service of the divorce petition. Arizona courts multiply this number by the 30% floor and the 50% ceiling to establish the minimum and maximum duration range. The court then positions the award within that range based on several computation factors listed in A.R.S. 25-319(B), including the standard of living during the marriage, the age and employment history of the requesting spouse, and the financial resources available to each party.
For marriages lasting fewer than 5 years, spousal maintenance awards are uncommon and typically short, ranging from several months to approximately 2 years. Mid-length marriages of 10 to 15 years generally produce awards of 3 to 7.5 years. Long-duration marriages of 20 years or more can result in maintenance lasting 6 to 10 years or longer, subject to the Rule of 65 discussed below.
The Rule of 65: Extended Duration for Older Spouses
The Rule of 65 extends spousal maintenance duration when the requesting spouse's age at the time of divorce plus the number of years married equals 65 or more. Under the Arizona Spousal Maintenance Guidelines, the Rule of 65 applied in approximately 32% of cases reviewed during the 2025 guideline revision process, with an average duration of 55 months. A 55-year-old spouse divorcing after 15 years of marriage (55 + 15 = 70) qualifies for the Rule of 65 and may receive maintenance for a longer period than the standard 30% to 50% formula would otherwise produce.
The Rule of 65 recognizes that older spouses who have been out of the workforce for extended periods face significantly greater barriers to achieving self-sufficiency. Arizona courts apply this rule because a spouse who is 60 years old after a 20-year marriage cannot reasonably be expected to re-enter the workforce and earn a self-sustaining income before retirement age. The rule does not guarantee lifetime or permanent maintenance, but it does allow courts to award durations that exceed the standard maximum cap when the combined age-and-duration threshold is met.
2025 Guideline Revisions: What Changed for Alimony Duration
The Arizona Supreme Court enacted significant revisions to the Spousal Maintenance Guidelines effective September 1, 2025, directly impacting how long alimony lasts in Arizona. The maximum duration cap increased from 8 years (96 months) to 12 years (144 months) for marriages lasting 16 years (192 months) or more. If 50% of the marriage length exceeds 12 years, that longer figure applies instead, meaning a 30-year marriage could produce a duration of up to 15 years.
| Guideline Element | Before Sept. 2025 | After Sept. 2025 |
|---|---|---|
| Maximum duration cap | 8 years (96 months) | 12 years (144 months) |
| Long-marriage threshold | 16+ years | 16+ years (unchanged) |
| 50% override | Not available | If 50% of marriage > 12 years, that applies |
| High-income adjustment threshold | $100,000 | $175,000 |
| Maximum high-income reduction | 80% | 70% |
| Mortgage principal | Included in calculation | Removed from calculation |
| Rule of 65 | Applied | Applied (unchanged) |
The high-income adjustment threshold also changed substantially. Under the prior guidelines, the adjustment began at $100,000 of combined income. The revised guidelines raised that threshold to $175,000, meaning fewer cases trigger the high-income reduction. The maximum adjustment decreased from 80% to 70%, which reduces spousal maintenance awards at higher income levels. Removing mortgage principal from the calculation means lower awards in cases where mortgage payments previously inflated the guideline range.
Eligibility: Who Qualifies for Spousal Maintenance in Arizona
A spouse must satisfy at least one of five eligibility criteria under A.R.S. 25-319(A) before an Arizona court will consider awarding spousal maintenance. The requesting spouse must demonstrate that they lack sufficient property to meet their reasonable needs, lack adequate earning ability to be self-sufficient, are the custodial parent of a young child requiring at-home care, made significant financial or career contributions to the other spouse's advancement, or were in a long-duration marriage and are of an age that precludes adequate employment.
The five statutory eligibility factors under A.R.S. 25-319(A) are:
- The spouse lacks sufficient property, including property apportioned in the divorce, to provide for reasonable needs
- The spouse is unable to be self-sufficient through appropriate employment in the labor market
- The spouse is the custodial parent of a child whose age or condition requires the parent to remain home
- The spouse made significant financial or other contributions to the other spouse's education, training, career, or earning ability, or significantly reduced their own income or career opportunities for the other spouse's benefit
- The spouse was in a marriage of long duration and is of an age that may preclude gaining adequate employment
Meeting one or more of these criteria establishes eligibility. The court then applies the Spousal Maintenance Guidelines to determine the amount and duration of the award. Arizona courts must make their maintenance determinations without regard to marital misconduct under A.R.S. 25-319, meaning infidelity, abandonment, or other fault-based conduct does not affect eligibility, amount, or duration.
How Spousal Maintenance Amount Is Calculated
The Arizona Spousal Maintenance Guidelines calculate the maintenance amount using the income differential between the spouses, targeting an award that enables the lower-earning spouse to achieve self-sufficiency. The Arizona Supreme Court provides an official Spousal Maintenance Calculator on the Arizona Courts website (azcourts.gov) that attorneys and self-represented parties use to determine the guideline amount. Courts must apply the guideline amount unless a written finding establishes that the guidelines would be inappropriate or unjust under A.R.S. 25-319(B).
Factors the court considers when positioning the award within the guideline range include the standard of living established during the marriage, the age, employment history, earning ability, and physical and emotional condition of the requesting spouse, the paying spouse's ability to meet their own needs while paying maintenance, the financial resources apportioned to each spouse in the property division, and the time necessary for the requesting spouse to acquire education or training for appropriate employment. Arizona is a community property state, so the 50/50 division of marital assets under A.R.S. 25-211 directly affects the maintenance calculation by determining each spouse's post-divorce financial position.
When Does Alimony End in Arizona: Termination Events
Spousal maintenance in Arizona automatically terminates upon the death of either party or the remarriage of the receiving spouse under A.R.S. 25-327(B). Remarriage terminates the obligation immediately and does not require a court order, though filing a notice with the court to update official records is advisable. Death of the paying spouse also terminates the obligation unless the divorce decree specifically provides for maintenance to continue from the estate.
Cohabitation does not automatically terminate spousal maintenance in Arizona. Unlike remarriage, which triggers automatic termination under A.R.S. 25-327(B), a paying spouse who believes the recipient's financial situation has substantially improved due to cohabitation must petition the court for modification or termination. The paying spouse bears the burden of proving a substantial and continuing change in circumstances under A.R.S. 25-327(A).
The five events that end spousal maintenance in Arizona are:
- The maintenance term set in the court order expires
- The receiving spouse remarries (automatic termination)
- Either spouse dies (automatic termination)
- The court grants a modification petition based on substantial and continuing changed circumstances
- The parties reach a written agreement to terminate maintenance
Parties may contractually override the automatic termination provisions. If the divorce decree or a separation agreement expressly states that maintenance survives remarriage or death, those terms control. However, the decree language must be sufficiently explicit to meet the statutory requirement under A.R.S. 25-327(B), and courts construe ambiguous language in favor of the statutory default of termination upon remarriage.
Modifying Spousal Maintenance Duration in Arizona
Either spouse may petition to modify the duration or amount of spousal maintenance by demonstrating a substantial and continuing change in circumstances under A.R.S. 25-327(A). Common grounds for modification include job loss, serious illness or disability, significant income changes for either party, retirement of the paying spouse, or the receiving spouse's completion of education or training that substantially improves earning capacity. The requesting party bears the burden of proving the change is both substantial and continuing, not temporary or speculative.
Arizona courts will not modify maintenance based on temporary setbacks or minor income fluctuations. A paying spouse who loses a job must demonstrate that the unemployment is involuntary and ongoing, not a brief gap between positions. Conversely, a receiving spouse who obtains employment at a lower salary than anticipated may petition for extended duration if the original award was based on projected earning capacity that did not materialize. Courts retain jurisdiction to modify maintenance until the award's expiration date unless the decree expressly waives modification rights.
Arizona Divorce Filing Requirements and Costs
Filing for divorce in Arizona requires that at least one spouse has been domiciled in the state for a minimum of 90 days before filing the petition, as established by A.R.S. 25-312. Military members stationed in Arizona for 90 continuous days satisfy this requirement even if their legal domicile is in another state. After serving the petition on the other spouse, Arizona imposes a mandatory 60-day waiting period before the court will hold a hearing or enter a decree of dissolution.
The filing fee for a Petition for Dissolution of Marriage in Arizona ranges from $349 to $360, depending on the county. Maricopa County (Phoenix) charges approximately $349 for the initial petition. The responding spouse pays approximately $279 to file a Response. Fee waiver applications (deferral/waiver) are available for parties who cannot afford court costs. If minor children are involved, the children must have resided in Arizona for at least 6 months for the court to exercise custody jurisdiction under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA).
Types of Spousal Maintenance Awards in Arizona
Arizona courts issue three types of spousal maintenance awards, each serving a different purpose and lasting for different periods. Rehabilitative maintenance is the most common type, designed to support the receiving spouse while they obtain education, training, or work experience needed to become self-sufficient. Compensatory maintenance reimburses a spouse who made significant contributions to the other spouse's career or education during the marriage. Long-term maintenance provides extended support for spouses in long-duration marriages who face age-related or health-related barriers to self-sufficiency.
Rehabilitative maintenance typically lasts 2 to 5 years and is tied to a specific plan for the receiving spouse to gain employability. Compensatory maintenance duration reflects the magnitude of the contribution made and may be shorter but at a higher monthly amount. Long-term maintenance, sometimes awarded under the Rule of 65, can extend to the maximum duration cap of 12 years or beyond if 50% of the marriage length exceeds that cap. Arizona law does not formally recognize "permanent" or "lifetime" maintenance as a distinct category, though long-term awards may effectively last until retirement age or death.
Frequently Asked Questions
How long does alimony last in Arizona for a 10-year marriage?
For a 10-year (120-month) marriage, Arizona spousal maintenance typically lasts 36 to 60 months (3 to 5 years) under the guideline formula of 30% to 50% of marriage duration. The court positions the award within that range based on factors in A.R.S. 25-319(B), including the requesting spouse's earning capacity, age, and the marital standard of living.
Can alimony be permanent in Arizona?
Arizona does not formally award permanent or lifetime spousal maintenance. The 2025 revised guidelines cap duration at 12 years for marriages of 16 years or more, though the Rule of 65 can extend duration when the spouse's age plus years married equals 65 or greater. For a 30-year marriage, the 50% override allows up to 15 years of maintenance under A.R.S. 25-319.
Does remarriage end alimony in Arizona?
Yes. Under A.R.S. 25-327(B), the receiving spouse's remarriage automatically terminates the paying spouse's obligation to pay future spousal maintenance. Termination is immediate and does not require a separate court order, though notifying the court is recommended. The parties can contractually override this provision only with sufficiently explicit written language in the decree.
Does cohabitation affect spousal maintenance in Arizona?
Cohabitation does not automatically terminate spousal maintenance in Arizona, unlike remarriage. The paying spouse must file a petition to modify or terminate maintenance and demonstrate a substantial and continuing change in the receiving spouse's financial circumstances under A.R.S. 25-327(A). Courts evaluate whether the cohabitation arrangement has materially reduced the recipient's financial need.
How is the amount of spousal maintenance calculated in Arizona?
Arizona calculates spousal maintenance using the official Spousal Maintenance Calculator based on guidelines approved by the Arizona Supreme Court effective September 1, 2025. The calculation considers the income differential between spouses, with the high-income adjustment threshold set at $175,000 and a maximum reduction of 70%. Courts must apply the guideline amount unless a written finding of inappropriateness is made under A.R.S. 25-319(B).
What is the Rule of 65 for spousal maintenance in Arizona?
The Rule of 65 applies when the requesting spouse's age at divorce plus the number of years married totals 65 or more. This rule extends the allowable maintenance duration beyond the standard 30% to 50% formula, recognizing that older spouses face greater barriers to self-sufficiency. Approximately 32% of reviewed Arizona spousal maintenance cases involved the Rule of 65, with an average awarded duration of 55 months.
Can spousal maintenance be modified after the divorce is final?
Yes. Either party may petition to modify the amount or duration of spousal maintenance by proving a substantial and continuing change in circumstances under A.R.S. 25-327(A). Common qualifying changes include involuntary job loss, serious illness, significant income changes, or the receiving spouse's improved earning capacity. The court retains modification jurisdiction until the maintenance award expires.
Does marital misconduct affect alimony in Arizona?
No. Arizona courts must determine spousal maintenance without regard to marital misconduct under A.R.S. 25-319. Infidelity, abandonment, substance abuse, or other fault-based conduct does not affect eligibility, amount, or duration of maintenance. Arizona is a no-fault divorce state, and the sole ground for dissolution is irretrievable breakdown of the marriage under A.R.S. 25-312.
How long do I have to be married to get alimony in Arizona?
Arizona has no minimum marriage duration requirement for spousal maintenance eligibility. A spouse in a short-term marriage (under 5 years) may qualify if they meet at least one of the five eligibility criteria under A.R.S. 25-319(A). However, shorter marriages typically produce shorter maintenance awards under the 30% to 50% duration formula, often ranging from several months to 2 years.
What happens to alimony if the paying spouse dies in Arizona?
Spousal maintenance automatically terminates upon the death of the paying spouse under A.R.S. 25-327(B), unless the divorce decree expressly provides for continued payments from the decedent's estate. To protect against this risk, receiving spouses often negotiate for life insurance provisions in the divorce decree requiring the paying spouse to maintain a policy naming the receiving spouse as beneficiary for the duration of the maintenance obligation.
