Arizona Family Law Statutes: Marriage, Divorce, Custody, and Support

Arizona family law is concentrated in Title 25 of the Arizona Revised Statutes, which governs marriage, divorce, legal separation, child custody, parenting time, child support, spousal maintenance, and the division of property. Arizona is a community property state, so the default rules for splitting assets and debts differ substantially from the equitable distribution model used in most other states. The system is no-fault for standard marriages, best-interests-driven for anything involving children, and administered through the state’s superior courts.

Getting Married in Arizona

Both people generally must be at least 18. A 16- or 17-year-old can marry only with a custodial parent or guardian’s consent, or with a court emancipation order, and the other spouse cannot be more than three years older. Anyone under 16 is barred from marrying regardless of consent.¹

A marriage license from the clerk of the superior court is required. There is no waiting period between issuance and the ceremony, and the license stays valid for one year. Someone legally authorized to solemnize marriages, such as a judge or clergy member, must perform the ceremony, and the signed license goes back to the county clerk for recording. Failing to record does not void the marriage but can cause problems later when you need to prove it exists.²

Arizona does not allow common-law marriages to be formed inside the state. A valid common-law marriage established in a state that recognizes them before you moved will be honored here.³ Marriages between close relatives are prohibited, including parents and children at any generational distance, siblings and half-siblings, and aunts or uncles with nieces or nephews. First cousins can marry only if both are 65 or older, or if a superior court judge approves the marriage after one cousin proves inability to reproduce.⁴

Covenant Marriage

Arizona also offers a separate legal track called covenant marriage. Couples choosing it sign a written declaration that the marriage is a lifelong commitment and complete premarital counseling with a clergy member or marriage counselor, who provides a notarized statement confirming the counseling covered the seriousness of the commitment and the limited grounds for ending it.⁵

A covenant marriage cannot be dissolved on a simple finding that it is irretrievably broken. The spouse seeking divorce must prove one of the statutory grounds:

Adultery by the other spouse
Felony conviction resulting in a death sentence or imprisonment
Abandonment of the marital home for at least one year
Physical or sexual abuse of the filing spouse, a child, or a family member living in the home
Domestic violence or emotional abuse
Living apart continuously for at least two years without reconciliation
Living apart for at least one year after a decree of legal separation
Habitual drug or alcohol abuse
Mutual agreement to dissolve the marriage

These grounds apply only where both spouses actually entered a covenant marriage. If the proper declaration was never filed, the standard no-fault rules govern.⁶

Prenuptial Agreements

Arizona follows a version of the Uniform Premarital Agreement Act. A valid prenuptial agreement must be in writing and signed by both parties, and no consideration beyond the marriage itself is needed to make it enforceable.⁷

An agreement can be challenged on two grounds. One, the person contesting it did not sign voluntarily. Two, the agreement was unconscionable when signed and the challenging spouse was not given fair disclosure of the other party’s finances, did not waive that disclosure in writing, and did not otherwise have adequate knowledge of the other party’s financial situation. All three of those conditions must exist alongside unconscionability for that second challenge to succeed.⁷

One limit worth knowing: even if the agreement eliminates or reduces spousal maintenance, a court can override that provision if enforcing it would leave the disadvantaged spouse eligible for public assistance at the time of divorce. The agreement takes effect when the couple marries.

Filing for Divorce

Arizona uses a no-fault system. You do not need to prove your spouse did anything wrong; the required finding is that the marriage is “irretrievably broken.” At least one spouse must have been domiciled in Arizona, or stationed here as a service member, for at least 90 days before filing.⁸

The petitioner files a Petition for Dissolution of Marriage with the superior court and has the respondent served. An in-state respondent has 20 days to file a written response; an out-of-state respondent gets 30 days. Miss those deadlines and the petitioner can seek a default judgment.⁹

No matter how quickly the spouses agree, the court cannot finalize the divorce until at least 60 days after the respondent was served.¹⁰ When both parties agree on all terms, they can submit a consent decree and skip a trial. Contested cases move to mediation or, ultimately, trial, where the judge resolves disputes over property, custody, and support.

Legal Separation as an Alternative

Legal separation lets a court resolve the same issues addressed in a divorce, including custody, parenting time, property division, and support, while leaving the marriage itself intact. Couples use it for religious reasons, to preserve health insurance tied to marital status, or when they are not ready to end the marriage permanently.¹¹

Legal separation requires that neither spouse objects. If the respondent wants a divorce instead, the case converts to a dissolution proceeding once residency is met. Covenant marriages have their own specific grounds for legal separation, similar to those required for dissolution.¹¹

How Property and Debt Are Divided

Nearly everything either spouse acquires during the marriage belongs to both spouses equally as community property, including wages, real estate, vehicles, retirement accounts, and business interests. Property that one spouse received as a gift or inheritance, and anything owned before the marriage, remains that spouse’s separate property.¹²

The line blurs when assets get mixed. Depositing an inheritance into a joint bank account, or using marital funds to renovate a home one spouse owned before the wedding, can turn separate property into contested territory. The spouse claiming an asset is separate carries the burden of proving it with clear evidence.

Debts follow a similar structure. Either spouse can incur debt for the benefit of the community, and the community property is liable for that obligation. Both spouses generally must be named in a lawsuit seeking to collect a community debt. Separate property of one spouse is not liable for the other spouse’s separate debts unless that spouse agreed to it.¹³ A court dividing property in a divorce can assign a disproportionate share of debt to a spouse who incurred it recklessly, such as through gambling losses.

Spousal Maintenance

Arizona courts can award spousal maintenance to either spouse during a divorce or legal separation. A spouse qualifies if the court finds one of the following applies:

The spouse lacks enough property, including property received in the division, to cover reasonable needs.
The spouse cannot earn enough in the labor market to be self-sufficient.
The spouse is the primary caretaker of a young child or a child whose condition makes outside employment impractical.
The spouse made significant financial or career sacrifices for the other spouse’s benefit.
The marriage lasted long enough that the spouse’s age now limits the ability to find adequate employment.

¹⁴

Once a spouse qualifies, the court sets the amount and duration by weighing 13 statutory factors, including the standard of living during the marriage, its length, each spouse’s earning ability and health, financial resources on each side, and contributions to the other’s career. No single factor controls. The Arizona Supreme Court has issued guidelines, but courts can deviate when the guidelines would produce an unjust result.¹⁴

Either side can seek modification or termination on proof of a substantial and continuing change in circumstances. Remarriage of the receiving spouse is a common trigger.¹⁵

Child Custody and Parenting Time

Arizona uses “legal decision-making” for what many people call legal custody and “parenting time” for physical custody. Both are decided on the child’s best interests, considering a set of statutory factors:

Each parent’s past, present, and potential future relationship with the child
The child’s relationships with siblings and other significant people
The child’s adjustment to home, school, and community
The child’s wishes, if mature enough to express them
The mental and physical health of everyone involved
Which parent is more likely to encourage frequent, meaningful contact with the other parent
Whether either parent tried to mislead the court or cause unnecessary delay
Any history of domestic violence or child abuse
Whether coercion or duress played a role in any custody agreement

A domestic violence history carries heavy weight. A parent with such a history faces a legal presumption against receiving sole or joint legal decision-making authority.¹⁶

Joint Versus Sole Decision-Making

Joint legal decision-making gives both parents shared authority over major choices about the child’s healthcare, education, and religious upbringing, with neither parent’s rights superior, though a court order can assign specific decisions to one. Sole legal decision-making gives one parent exclusive authority over those decisions, though it does not automatically change the parenting time schedule.¹⁶ Courts favor joint arrangements unless the evidence shows cooperation between the parents would harm the child.

Relocating With a Child

When both parents have joint decision-making or parenting time rights and both live in Arizona, a parent who wants to move with the child must give the other parent at least 45 days’ written notice by certified mail. That requirement applies when the proposed move is out of state or more than 100 miles within Arizona.¹⁷

The non-moving parent has 30 days after notice to file a petition asking the court to block the move. Miss that window and any later challenge requires a showing of good cause. At a relocation hearing, the parent who wants to move must prove the relocation serves the child’s best interests. Moving without following the notice rules can trigger sanctions affecting custody or parenting time.¹⁷

Modifying a Custody Order

You generally cannot ask to modify a custody order until at least one year after it was entered. The exception is urgency: sworn statements showing that the child’s current environment may seriously endanger physical, mental, or emotional health can get the motion heard sooner.¹⁸ Joint custody orders can be modified at any time on evidence of domestic violence, spousal abuse, or child abuse since the order was entered. After a joint custody order has been in place for six months, a parent can also seek modification based on the other parent’s failure to comply with its terms.

Child Support

Both parents share financial responsibility for their children. Arizona uses the Income Shares Model, which estimates what the parents would have spent on the child had they stayed together and divides that amount proportionally based on each parent’s income.¹⁹

The base calculation starts with each parent’s gross income and adjusts for additional child-related expenses, including health insurance premiums paid for the child, childcare costs, and extraordinary expenses. Courts can deviate from the guideline amount when applying the standard formula would produce an unjust or inappropriate result.²⁰

Support normally continues until the child turns 18. If the child is still in high school at 18, support continues until graduation but not past the child’s 19th birthday.²¹ Courts can extend support beyond those limits for a child with a serious disability.

Enforcement and Modification

The Arizona Department of Economic Security’s Division of Child Support Services handles enforcement.²² When a parent willfully falls at least six months behind, enforcement can include suspending or restricting a driver’s license, revoking professional or occupational licenses, and invalidating recreational and wildlife licenses.²³ Other tools include income withholding orders sent to employers, tax refund intercepts, and contempt of court proceedings that can carry fines or jail time.

Either parent can seek a modification by showing a substantial and continuing change in circumstances, such as a significant income change, a change in the child’s medical needs, or a change in available health insurance coverage.¹⁵

Protective Orders

Arizona offers two civil protective orders, and the right one depends on the relationship between the people involved.

Orders of Protection

An Order of Protection is for domestic violence situations, meaning the petitioner and respondent are spouses, former spouses, co-parents, current or former romantic partners, or household members. You file a verified petition with any magistrate, justice of the peace, or superior court judge in the state. If the court finds reasonable cause to believe the respondent may commit domestic violence or has done so within the past year, it can issue the order without a full hearing.²⁴

The order can prohibit contact, remove the respondent from a shared residence, restrict them from coming near your home or workplace, and, on a finding of credible threat to physical safety, bar firearm possession. An Order of Protection expires two years after it is served. A contested order goes to a hearing where both sides present evidence. Violating one is a criminal offense.²⁴

Injunctions Against Harassment

When there is no domestic relationship, such as harassment from a neighbor, coworker, or stranger, the correct filing is an Injunction Against Harassment. The petitioner must show a series of acts directed at them that would cause a reasonable person to feel seriously alarmed, annoyed, or harassed, and that the conduct serves no legitimate purpose.²⁵

The injunction can order the respondent to stop harassing you, stay away from your home, workplace, or school, and refrain from contacting you. It lasts one year after service, half the duration of an Order of Protection, and each injunction is limited to a single respondent.²⁵

Adoption and Guardianship

Arizona provides separate legal pathways for adoption and guardianship, with different levels of permanence and different effects on parental rights.

Adoption permanently transfers all parental rights and responsibilities from the biological parents to the adoptive parents. Prospective adoptive parents must obtain preadoption certification, which involves a home study. Biological parents must consent voluntarily or have their rights terminated by a court on grounds such as neglect, abandonment, or unfitness. Once finalized, the child has the same legal status as a biological child of the adoptive parents, including full inheritance rights. Arizona’s adoption statutes appear in Title 8, Chapter 1.

Guardianship lets someone take legal responsibility for a child without permanently ending the biological parents’ rights. Families use it when a parent cannot care for a child due to illness, military deployment, incarceration, or similar hardship. Guardianship can be revoked if the biological parents later show they can resume care. Guardians handle education, healthcare, and general welfare, and courts review the arrangements periodically to make sure the child’s needs are being met.
