Arizona Divorce Guide: Community Property, Residency & Filing Requirements

Introduction: Arizona's Divorce Landscape

Arizona consistently ranks among the states with the highest divorce rates in the country. With a transient population, a young demographic, and one of the nation's lowest residency thresholds, Arizona courts handle a substantial volume of divorce filings every year.

What makes Arizona unique is the intersection of two important legal frameworks: community property law — which governs how assets and debts are divided — and a pure no-fault system that makes it impossible to allege a spouse's wrongdoing as grounds for divorce. Understanding both before you file is essential.

This guide walks through Arizona's specific rules in plain English: residency requirements, grounds for divorce, how community property works, child custody terminology, spousal maintenance, and what to expect from start to finish.

Residency Requirements (90 Days)

To file for divorce (called a “Petition for Dissolution of Marriage”) in Arizona, at least one spouse must have been domiciled in Arizona for at least 90 days immediately before filing. This requirement is codified in Arizona Revised Statutes.

Note: Even after the petition is filed, Arizona still requires a 60-day waiting period after service before the divorce can be finalized. More on that in the Timeline section below.

Grounds for Divorce: Pure No-Fault State

Arizona is a pure no-fault divorce state under A.R.S. § 25-312. There is one — and only one — legal ground for divorce in Arizona:

This means fault is entirely removed from the divorce equation in Arizona. A spouse's misconduct does not affect whether the divorce is granted, how property is divided, or whether spousal maintenance is awarded. Courts focus on the financial picture and the best interests of children — not on who caused the breakdown.

There is one exception: if the marriage is a covenant marriage (a special form available in Arizona, Louisiana, and Arkansas), different grounds and waiting periods apply. Standard marriages in Arizona are not covenant marriages unless both spouses specifically elected that designation.

Community Property in Arizona

Arizona is one of only 9 community property states in the U.S. (the others are California, Washington, Nevada, Idaho, Louisiana, New Mexico, Texas, and Wisconsin). The core rule is straightforward: all property acquired by either spouse during the marriage is presumed to be community property — owned equally (50/50) by both spouses, regardless of whose name is on the account, deed, or paycheck.

At divorce, Arizona courts divide the community estate equally. Here is how the two categories break down:

Child Custody & Support

Arizona uses distinct terminology that differs from most other states. What most people call “custody” is split into two separate concepts:

Child support in Arizona is calculated using the Arizona Child Support Guidelines, which use an income shares model. The guidelines factor in both parents' gross incomes, the number of children, parenting time percentages, health insurance costs, and childcare expenses. The result is a presumptive amount — courts can deviate from the guideline figure if special circumstances justify it.

Child support orders in Arizona continue until the child turns 18 (or graduates high school, whichever is later — but not past age 19). Either parent can request a modification if there is a substantial and continuing change in circumstances.

Spousal Maintenance

Spousal maintenance (Arizona's term for alimony) is discretionary under A.R.S. § 25-319. There is no fixed formula. A court will first determine whether a spouse qualifies for maintenance, then separately determine the amount and duration.

A spouse may qualify for maintenance if they demonstrate one or more of the following:

Once a spouse qualifies, the court weighs these factors to determine the amount and duration:

Because there is no formula, maintenance outcomes in Arizona can vary significantly. Spousal maintenance is most common in long marriages where one spouse left the workforce to raise children or support the other's career. It is typically time-limited — designed to bridge the gap until the receiving spouse can become self-supporting.

Arizona Divorce Timeline

Arizona has a mandatory 60-day waiting period under A.R.S. § 25-329. The divorce cannot be finalized before those 60 days have passed from the date the respondent is served — even if both spouses agree on everything from the start.
