How is Spousal Maintenance Calculated in Arizona?

Arizona calls it "spousal maintenance" — not alimony — and the process works differently here than in most states. Before a court calculates how much or how long, a spouse must first qualify for maintenance by meeting at least one of five specific eligibility factors. If none of those factors apply, maintenance may not be available regardless of the income gap. Only after qualifying does the court move to amount and duration — using the 2022 Arizona Spousal Maintenance Guidelines, which courts are required to apply for petitions filed after September 24, 2022.

The guidelines are meaningful. They produce a range — not a single number — and cap duration at 96 months for most marriages. The exception is the Rule of 65, which may allow longer awards for older spouses in long marriages.

Step One: Qualifying for Maintenance

Under A.R.S. § 25-319(A), a court may award spousal maintenance only if the requesting spouse meets at least one of the following five factors:

Factor 1 — Insufficient property. The spouse lacks sufficient property, including any property assigned to them in the divorce, to provide for their reasonable needs. This is the most commonly met factor. "Reasonable needs" is evaluated in the context of the marital standard of living — not bare subsistence.

Factor 2 — Inadequate earning ability. The spouse lacks earning ability in the labor market adequate to be self-sufficient. This includes situations where the spouse's skills, education, or work history leave them unable to find employment that covers reasonable living expenses.

Factor 3 — Primary caregiver of a young child. The spouse is the primary caregiver of a child whose age or condition makes it inappropriate to require that parent to seek employment outside the home. This is most often applied when a child has significant medical needs or disabilities.

Factor 4 — Career sacrifice or contribution to the other spouse. The spouse made significant financial or other contributions to the education, career, or earning ability of the other spouse — or significantly reduced their own income or career opportunities for the benefit of the other. A classic example: one spouse worked to put the other through a professional degree program, then saw that investment pay off in the other spouse's higher earnings.

Factor 5 — Long marriage, age precludes self-sufficiency. The marriage was of long duration and the requesting spouse's age may preclude gaining employment adequate to be self-sufficient.

A spouse only needs to meet one of these factors to qualify. In practice, Factors 1, 2, and 5 apply to the largest number of Arizona divorces. Once a factor is established, the court moves to the calculation phase.

Step Two: Calculating the Amount — The 2022 Guidelines

For cases filed after September 24, 2022, Arizona courts are required to use the state's spousal maintenance guidelines and the associated calculator. The guidelines produce a recommended range for the monthly maintenance amount — not a single prescribed figure. Courts may deviate from the range if they make written findings explaining the deviation.

The guidelines consider both spouses' gross monthly incomes, the family's expenses during the marriage (using Bureau of Labor Statistics Consumer Expenditure Survey data as a benchmark), and any existing child support obligations. The calculation essentially asks: given both spouses' incomes and the family's spending pattern, what transfer — if any — would produce a reasonable outcome for the lower-earning spouse?

The guidelines are oriented toward self-sufficiency: the statute provides that maintenance should be awarded "only for a period of time and in an amount necessary to enable the receiving spouse to become self-sufficient." Courts don't aim to equalize incomes permanently — they aim to bridge the gap while the receiving spouse builds toward financial independence.

Duration: 12 to 96 Months, Tied to Marriage Length

The 2022 guidelines tie maintenance duration to the length of the marriage. The general framework under the guidelines produces the following duration ranges:

Duration ranges reflect the general framework of the 2022 Arizona Spousal Maintenance Guidelines. Courts have discretion to deviate from these ranges based on specific circumstances.

Courts retain discretion to deviate from the guideline duration — shorter or longer — based on written findings. A shorter marriage with an unusual set of circumstances (such as a significant career sacrifice or health issue) might receive a longer award than the standard range. A longer marriage where the receiving spouse has strong earning capacity might receive a shorter one.

The Rule of 65: Extended Duration for Older Spouses

The Rule of 65 creates an exception to the standard duration ranges. It applies when all three of the following conditions are met: the requesting spouse is older than 42, the marriage lasted more than 16 years, and the sum of the requesting spouse's age and the length of the marriage is 65 or greater.

When the Rule of 65 applies, maintenance may extend beyond the 96-month cap. Courts look at the realistic employment prospects for the requesting spouse given their age, the gap since they last worked full-time, and the standard of living during the marriage. The rule acknowledges that for some spouses — typically those in their 50s and 60s who left the workforce during a long marriage — the standard duration caps are insufficient.

How Maintenance Ends in Arizona

Remarriage of the recipient terminates maintenance automatically in Arizona by operation of law. The paying spouse doesn't need to file a motion — the obligation ends at remarriage.

Death of either party terminates maintenance unless the divorce agreement specifically provides for continuation through a life insurance arrangement or similar mechanism.

Cohabitation does not automatically terminate maintenance in Arizona. A paying spouse who believes the recipient is living with a new partner may file a motion to modify — but must demonstrate that the cohabitation meaningfully changes the recipient's financial circumstances. Courts look at financial interdependence, not simply whether the recipient shares a home with someone.

Substantial change in circumstances allows either party to seek modification at any time. Job loss, a significant income change for either spouse, or a major health change may qualify. Arizona courts require that the change be substantial and continuing — not temporary or minor.
