To file for divorce in Arizona, at least one spouse must have been domiciled in the state for 90 days before the petition is filed, a threshold set by Arizona Revised Statutes 25-312.1Arizona Legislature. Arizona Code 25-312 – Dissolution of Marriage; Findings Necessary That 90-day rule is the headline requirement, but it is not the only one. The court also needs the right venue within the state, personal jurisdiction over your spouse before it can divide property or order support, and a separate basis for jurisdiction over anything involving your children. Missing any piece can delay your case, limit what the judge can order, or leave your decree open to being set aside.
The 90-Day Domicile Rule
The statute is written in mandatory language: the court “shall” enter a decree only if it finds that one of the spouses was domiciled in Arizona for at least 90 days before the petition was filed. Active-duty military members stationed in Arizona qualify the same way, provided they have maintained that presence for the same 90-day window.1Arizona Legislature. Arizona Code 25-312 – Dissolution of Marriage; Findings Necessary If neither spouse meets the threshold, the court lacks subject-matter jurisdiction and any decree it enters is vulnerable to being voided.
Domicile is more than a mailing address. It requires physical presence combined with the intent to make Arizona your permanent home. Someone who moved to Tucson last month for a temporary work assignment, planning to return to Colorado, has not established domicile even with a rented apartment and an Arizona driver’s license. Courts look at the totality of the circumstances, so keep records that show your intent to stay: a signed lease, voter registration, vehicle registration, employment ties.
The court must also find that the marriage is “irretrievably broken” before dissolving it. If one spouse denies that under oath, the judge can order a hearing or delay the case for up to 60 additional days to explore whether reconciliation is possible.1Arizona Legislature. Arizona Code 25-312 – Dissolution of Marriage; Findings Necessary
Which County You File In
Residency gets you into Arizona’s court system. Venue decides which county court actually hears the case. Arizona law requires that a divorce be filed in the county where the petitioner lives at the time the action is filed.2Arizona Legislature. Arizona Revised Statutes 12-401 – Venue You do not get to pick your spouse’s county, even if it would be more convenient for both of you.
Filing in the wrong county does not void the case the way failing the 90-day rule does. Venue errors are procedural, and the respondent can ask for a transfer to the correct county. A transfer can still add weeks or months to your timeline, so get it right at the outset.
Personal Jurisdiction Over Your Spouse
Meeting the residency rule gives the court authority over the marriage itself. Dividing property, ordering spousal maintenance, or entering enforceable financial orders against your spouse requires a second kind of authority: personal jurisdiction over that person.
Arizona takes this as broadly as the U.S. Constitution allows. The court looks at whether your spouse has enough ties to the state that being brought into court here is fundamentally fair. Living in Arizona during the marriage, owning property here, or conducting business in the state all count. A spouse who has never set foot in Arizona and has no connection to the state is a much harder case.
The practical consequence is sharp. Without personal jurisdiction over your spouse, the court can still grant the divorce itself, but it cannot divide out-of-state assets, order maintenance payments, or make enforceable financial orders against the absent spouse. You end up legally single while unable to resolve the financial side of the marriage in Arizona.
That matters more here than in many states because Arizona is a community property state. Virtually everything acquired by either spouse during the marriage is community property, with narrow exceptions for gifts, inheritances, and property acquired after the petition is served.3Arizona Legislature. Arizona Code 25-211 – Property Acquired During Marriage as Community Property The court must divide this property equitably, though not necessarily 50/50, and without considering fault.4Arizona Legislature. Arizona Code 25-318 – Disposition of Property; Retroactivity; Notice to Creditors Property acquired outside Arizona counts as community property if it would have been community property had it been acquired here, which matters for couples who moved to the state after accumulating assets elsewhere.
ARS 25-318 contemplates what happens when personal jurisdiction is missing: it allows a separate proceeding to divide property after dissolution “by a court that previously lacked personal jurisdiction over the absent spouse.”4Arizona Legislature. Arizona Code 25-318 – Disposition of Property; Retroactivity; Notice to Creditors That is a fallback, not a plan. Establishing personal jurisdiction at the start saves you from relitigating finances later.
When Arizona Can Decide Custody
If children are involved, do not assume that qualifying for divorce in Arizona also lets Arizona decide custody. Custody follows a separate jurisdictional test under the Uniform Child-Custody Jurisdiction and Enforcement Act, codified in ARS 25-1031. The core rule: Arizona has jurisdiction to make an initial custody determination if the state is the child’s “home state,” meaning the child lived here with a parent for at least six consecutive months immediately before the case was filed.5Arizona Legislature. Arizona Code 25-1031 – Initial Child Custody Jurisdiction
Arizona also qualifies if it was the child’s home state within the past six months, the child has since left, and a parent still lives here. This comes up when one parent moves with the child shortly before a divorce is filed.
The gap people miss: meeting the 90-day residency rule for divorce does not automatically give Arizona jurisdiction over custody. If your child has lived in another state for the past six months, that state likely has home-state jurisdiction, and you may need to litigate custody there even while Arizona handles the divorce. In emergencies involving abuse or abandonment, Arizona courts can exercise temporary jurisdiction regardless of home-state status, but those orders are temporary and give way to the home state’s authority once the crisis passes.
When Arizona Can Modify Child Support
Child support has its own framework under the Uniform Interstate Family Support Act, with Arizona’s version starting at ARS 25-1225. It follows a principle called “continuing, exclusive jurisdiction.” The state that issues the original child support order keeps exclusive power to modify it as long as at least one party (the obligor, the obligee, or the child) still lives there.6Arizona Legislature. Arizona Revised Statutes Title 25 – Marital and Domestic Relations
If an Arizona court sets your support amount and both you and your ex later move to different states, Arizona loses exclusive jurisdiction and either new state can seek to modify the order. If even one of you remains in Arizona, only an Arizona court can change the amount. Both parties can agree in writing to let another state take over, but without that agreement the original state keeps control. Worth knowing before anyone plans a post-divorce move.
Covenant Marriage Is Different
Most Arizona divorces are no-fault. The court just needs to find the marriage is irretrievably broken. Covenant marriages, which couples can elect at the time they marry, do not qualify for no-fault dissolution. If you entered a covenant marriage in Arizona or in another state that recognizes them, the petitioner must prove at least one of several specific grounds:
- Adultery by the respondent
- A felony conviction resulting in a sentence of death or imprisonment
- Abandonment of the marital home for at least one year
- Physical, sexual, or emotional abuse, or domestic violence
- Living apart for at least two continuous years without reconciliation
- Living apart for at least one year after a legal separation decree
- Habitual abuse of drugs or alcohol
- Mutual consent of both spouses to dissolve the marriage
The abandonment and separation grounds let a petitioner file early if the required time period is expected to be met, but the court will stay the case until the threshold is actually reached.7Arizona Legislature. Arizona Code 25-903 – Dissolution of a Covenant Marriage; Grounds If you are not sure whether yours is a covenant marriage, check the marriage certificate or the records from the county that issued your license.
The 60-Day Minimum
Even once you have cleared residency, venue, and service, Arizona imposes a mandatory cooling-off period. The court cannot hold a hearing, accept a motion supported by affidavit, or enter a final decree until 60 days after the respondent is served or accepts service.8Arizona Legislature. Arizona Code 25-329 – Waiting Period The clock runs from the date of service, not the date of filing. There are no exceptions for mutual agreement or uncontested cases.
Most divorces take considerably longer than 60 days, especially when children, disputed property, or spousal maintenance are involved. For couples with simple situations who have already agreed on everything, the 60-day minimum is the floor. Plan around it.
If Your Spouse Is on Active Duty
Federal law adds a protection that can slow things down when either spouse is an active-duty service member. Under the Servicemembers Civil Relief Act, an active-duty member who has been notified of a divorce proceeding can request a stay of at least 90 days. The service member must submit a statement explaining how current military duties prevent them from appearing, along with a letter from a commanding officer confirming that the duties prevent attendance and that leave is not authorized.9Office of the Law Revision Counsel. 50 USC 3932 – Stay of Proceedings When Servicemember Has Notice The court can grant further stays beyond the initial 90 days on additional application. This does not change whether you qualify to file in Arizona; it changes how fast the case can actually move.
