Arizona is a no-fault divorce state under A.R.S. § 25-312, meaning a spouse does not need to prove adultery or any other wrongdoing to file for divorce. The only ground required is that the marriage is "irretrievably broken." However, adultery divorce Arizona cases can still be affected by infidelity in three specific circumstances: when a cheating spouse wastes marital assets on an affair partner, when parental conduct affects child custody determinations, and when one spouse entered a covenant marriage where adultery serves as a specific ground for dissolution.

How Arizona's No-Fault Divorce System Treats Adultery
Arizona courts do not require proof of marital misconduct to grant a divorce, and under A.R.S. § 25-312, the court will dissolve a marriage when it finds the relationship is irretrievably broken with no reasonable prospect of reconciliation. This means a spouse can file for divorce without proving their partner committed adultery, abandonment, or abuse. The filing spouse need only assert that the marriage cannot be saved. In contested cases where one spouse denies the marriage is irretrievably broken, the court may order conciliation efforts before proceeding, but ultimately cannot force a couple to remain married.
For standard (non-covenant) marriages in Arizona, adultery itself carries no direct legal consequences in the divorce proceeding. Courts will not punish a cheating spouse by awarding the faithful spouse more property or higher alimony payments based solely on the affair. This differs significantly from fault-based states where infidelity can directly influence financial outcomes.
However, the no-fault framework does not mean adultery is completely irrelevant. Arizona law creates specific exceptions where a cheating spouse's conduct can affect divorce outcomes, particularly regarding the dissipation of marital assets, certain child custody considerations, and covenant marriages.
Adultery and Spousal Maintenance (Alimony) in Arizona
Under A.R.S. § 25-319, Arizona courts do not consider marital misconduct—including adultery—when determining whether to award spousal maintenance or calculating the amount and duration of support payments. Arizona spousal maintenance is designed solely to help a financially dependent spouse achieve self-sufficiency, not to punish wrongdoing. A spouse who committed adultery receives the same spousal maintenance consideration as a faithful spouse, provided they meet the eligibility criteria.
To qualify for spousal maintenance under A.R.S. § 25-319(A), a spouse must demonstrate at least one of five conditions: lacking sufficient property to provide for reasonable needs, lacking earning ability adequate for self-sufficiency, being the parent of a young child who should not work outside the home, having made significant contributions to the other spouse's education or career, or having a marriage of long duration combined with an age that prevents self-sufficiency.
The Arizona Supreme Court approved updated Spousal Maintenance Guidelines effective September 1, 2025, bringing greater predictability to support calculations. These guidelines use formulas based on income disparity and marriage duration—typically 30-50% of the income difference for 1-5 years depending on the length of the marriage—but adultery does not factor into these calculations under any circumstance.
Exception: Dissipation Affecting Support
While adultery itself does not affect alimony, courts may consider whether an unfaithful spouse dissipated marital assets by spending community funds on an affair partner. If a spouse used significant marital funds on gifts, travel, or housing for a paramour, the court could reduce that spouse's share of property or award compensatory payments. This reduction in property received could indirectly affect the financial analysis underlying spousal maintenance determinations.
How Adultery Affects Property Division in Arizona
Arizona is a community property state under A.R.S. § 25-318, meaning all property acquired during marriage is presumed to belong equally to both spouses and must be divided equitably upon divorce. The statute explicitly states that courts shall divide community property "without regard to marital misconduct." A cheating spouse is entitled to the same 50% presumptive share as a faithful spouse.
However, A.R.S. § 25-318(A) creates a critical exception for "excessive or abnormal expenditures, destruction, concealment or fraudulent disposition of community, joint tenancy and other property held in common." This dissipation doctrine allows courts to adjust property division when one spouse wasted marital assets, including spending on an extramarital affair.
Proving Dissipation in an Adultery Case
The Arizona Court of Appeals has ruled that expenditures on extramarital relationships constitute unreasonable and excessive use of community property. To make a dissipation claim, the innocent spouse must present prima facie evidence showing the other spouse engaged in excessive or abnormal expenditures. Common evidence includes unexplained withdrawals from bank accounts, credit card statements showing gifts or travel with a paramour, payments for a separate residence, or transfers of funds to an affair partner.
Once the claiming spouse establishes a prima facie case, the burden shifts to the spouse who made the expenditures to justify them. If the spending spouse cannot prove the funds were used for legitimate marital purposes, the court may award the innocent spouse a larger share of the remaining community property to compensate for the dissipated amount.
Court Remedies for Marital Waste
When one spouse dissipates marital assets through spending on an affair, Arizona courts can take several corrective actions under A.R.S. § 25-318(A):
- Award the innocent spouse a compensatory sum equal to their share of wasted assets
- Attribute the value of dissipated property to the wasting spouse's share
- Order reimbursement for proven dissipation amounts
- Adjust the overall property division to achieve equitable distribution
The default remains equal division, but courts have broad discretion to deviate from 50/50 when fairness requires an unequal split due to dissipation or other factors.
Adultery and Child Custody in Arizona
Arizona uses the "best interests of the child" standard under A.R.S. § 25-403 for all custody (legal decision-making) and parenting time determinations. While the state's no-fault divorce framework means adultery alone does not determine custody outcomes, a parent's conduct can be relevant when it affects the child's physical or emotional well-being.
Under A.R.S. § 25-403(A), courts must consider 11 statutory factors when making custody decisions, including the past, present, and potential future relationship between each parent and child, the child's adjustment to home, school, and community, and which parent is more likely to allow frequent and meaningful contact with the other parent. Courts will also consider the mental and physical health of all individuals involved.
When Adultery Can Affect Custody
Although infidelity itself is not a custody factor, Arizona courts may consider an affair if it demonstrates poor judgment affecting parenting ability or exposes children to inappropriate situations. Specific scenarios where adultery might influence custody decisions include:
- Exposing children to inappropriate adult relationships
- Prioritizing time with an affair partner over parenting responsibilities
- Introducing children to unstable romantic partners
- Using marital resources meant for children on an affair
- Creating a chaotic home environment due to the affair
In contested custody cases, the court will examine all factors affecting the child's best interests and may hold parental conduct against a parent if that behavior reduces stability or endangers the child. An affair that remained discreet and did not affect the children is unlikely to influence custody, while one that disrupted the family may carry weight.
Covenant Marriage: When Adultery Is a Direct Ground for Divorce
Arizona is one of only three states (along with Arkansas and Louisiana) that recognizes covenant marriages under A.R.S. § 25-903. Less than 1% of Arizona marriages are covenant marriages, but for couples who entered this type of union, adultery serves as a specific ground for divorce rather than being legally irrelevant.
What Makes Covenant Marriage Different
Couples entering a covenant marriage must undergo pre-marital counseling and sign a declaration of intent pledging to make all efforts to preserve the marriage, including attending counseling if difficulties arise. In exchange, they can only divorce for specific statutory reasons—no-fault divorce is not available.
Adultery as a Covenant Marriage Ground
Under A.R.S. § 25-903(A)(1), a spouse in a covenant marriage may file for divorce if the other spouse has committed adultery. The filing spouse must prove the infidelity occurred—simply claiming the marriage is irretrievably broken is insufficient. Other grounds under A.R.S. § 25-903 include felony conviction, abandonment for over one year, physical or sexual abuse, domestic violence, living separately for two or more years, habitual substance abuse, or mutual consent to divorce.
Proof Requirements for Covenant Divorce
Proving adultery in a covenant marriage divorce requires presenting evidence such as witness testimony, communications between the cheating spouse and affair partner, photographs, financial records showing expenditures on the affair, private investigator reports, or the cheating spouse's admission. The evidentiary burden is higher than in standard no-fault divorces where no proof of wrongdoing is required.
Arizona Divorce Filing Requirements and Timeline
Regardless of whether adultery is involved, all Arizona divorce filings must meet the same procedural requirements.
Residency Requirement
Under A.R.S. § 25-312(A)(1), at least one spouse must have been domiciled in Arizona for a minimum of 90 days before filing for divorce. Domicile requires both physical presence and the intent to remain in Arizona indefinitely as your permanent home. Military service members stationed in Arizona for at least 90 days may also file under this provision.
Filing Fees
The filing fee for a Petition for Dissolution of Marriage in Maricopa County is $349 as of April 2026. Verify with your local clerk. Other Arizona counties may have slightly different fees, with some charging separate amounts depending on whether children are involved—for example, Yuma County charges $364 with children and $324 without. If the filing spouse cannot afford court fees, they may petition for a fee waiver.
60-Day Waiting Period
Under A.R.S. § 25-329, Arizona requires a mandatory 60-day waiting period after the divorce petition is served on the responding spouse before the court can finalize the divorce. This "conciliation period" applies to all divorces, including uncontested cases where spouses agree on all terms. No exceptions or shortcuts exist—even if everything is resolved, the court cannot sign the final decree until day 61.
Typical Timelines
| Divorce Type | Typical Duration |
|---|---|
| Uncontested (all issues agreed) | 90-120 days |
| Contested (disputes present) | 6-18 months |
| Highly complex (business, custody) | 18-24+ months |
| Summary Consent Decree | 60-90 days |
The Summary Consent Decree option, introduced in 2022, allows couples who agree on all terms before filing to submit paperwork together. The 60-day clock starts on the filing date rather than the service date, potentially saving several weeks.
Gathering Evidence of Adultery in Arizona
Even though Arizona is a no-fault state, evidence of adultery may be relevant for dissipation claims or covenant marriage divorces.
Types of Useful Evidence
- Financial records showing spending on affair partner (gifts, travel, dining, housing)
- Bank statements with unexplained withdrawals
- Credit card bills revealing suspicious charges
- Phone records and text messages
- Social media posts or direct messages
- Photographs of the spouse with the affair partner
- Private investigator documentation
- Witness statements from friends, family, or coworkers
- Hotel receipts, plane tickets, or other travel documentation
Legal Limitations on Evidence Gathering
Arizona law prohibits certain methods of obtaining evidence. Spouses should not access password-protected accounts without permission, install tracking software without consent, record private conversations without the other party's knowledge (Arizona requires one-party consent for recordings), or engage in harassment or stalking behaviors. Improperly obtained evidence may be inadmissible and could expose the gathering spouse to civil or criminal liability.
Practical Steps After Discovering a Spouse's Adultery
Spouses who discover infidelity should take measured steps to protect their interests while remaining compliant with Arizona law.
- Consult with a family law attorney to understand your rights and options
- Preserve financial records documenting any suspected dissipation
- Avoid making major financial decisions or moving assets
- Maintain focus on children's well-being if applicable
- Consider whether reconciliation or divorce is your goal
- Understand that adultery alone will not increase your property share unless dissipation occurred
- Determine whether you have a standard or covenant marriage
- Gather evidence methodically and legally if you intend to make a dissipation claim
Frequently Asked Questions
Can I get more money in my Arizona divorce if my spouse cheated?
No, Arizona courts do not award higher alimony or a larger property share based solely on a spouse's adultery. Under A.R.S. § 25-318 and A.R.S. § 25-319, marital misconduct is not a factor in property division or spousal maintenance. However, if your spouse spent community funds on the affair—such as gifts, travel, or housing for an affair partner—you may claim dissipation and potentially receive compensation for your share of wasted assets.
Does Arizona consider adultery when deciding child custody?
Arizona courts determine custody based on the child's best interests under A.R.S. § 25-403, not on marital misconduct. Adultery alone does not affect custody. However, if the affair exposed children to inappropriate situations, disrupted their stability, or demonstrated poor parental judgment, those specific impacts could be considered as factors affecting the child's well-being.
What is the difference between a standard marriage and covenant marriage regarding adultery?
In a standard Arizona marriage, adultery is irrelevant to filing for divorce—you need only claim the marriage is irretrievably broken under A.R.S. § 25-312. In a covenant marriage under A.R.S. § 25-903, adultery is one of the specific grounds required to obtain a divorce. Less than 1% of Arizona marriages are covenant marriages.
How do I prove my spouse dissipated assets on an affair?
To prove dissipation, you must present prima facie evidence showing excessive or abnormal expenditures on the affair. Common evidence includes bank statements with unexplained withdrawals, credit card bills showing gifts or travel with a paramour, and payments for separate housing. Once you establish a basic case, the burden shifts to your spouse to justify the expenditures. The Arizona Court of Appeals has ruled that spending on extramarital relationships constitutes unreasonable use of community property.
How long does an adultery-related divorce take in Arizona?
The timeline depends on whether your divorce is contested or uncontested, not on whether adultery occurred. All Arizona divorces require a minimum 60-day waiting period under A.R.S. § 25-329. Uncontested divorces typically take 90-120 days total, while contested cases take 6-18 months. Complex cases involving dissipation claims may take longer due to additional discovery and evidentiary requirements.
Can adultery affect my alimony if my spouse spent money on the affair?
Adultery itself does not affect spousal maintenance calculations under A.R.S. § 25-319. However, if your spouse dissipated marital assets by spending on an affair partner, the court may adjust property division to compensate you. This reduced property share could indirectly affect the financial analysis underlying spousal maintenance, though the adultery itself remains legally irrelevant to support calculations.
What are the grounds for divorce in Arizona?
For standard marriages, Arizona requires only one ground: that the marriage is irretrievably broken under A.R.S. § 25-312. You do not need to prove adultery, abuse, abandonment, or any other misconduct. For covenant marriages, you must prove one of the specific grounds under A.R.S. § 25-903, including adultery, felony conviction, abandonment, abuse, two years of separation, habitual substance abuse, or mutual consent.
Is adultery illegal in Arizona?
As of 2026, adultery is not a criminal offense in Arizona. While adultery was technically illegal under older Arizona statutes, the law has been reformed, and extramarital affairs carry no criminal penalties. However, infidelity can still have civil consequences in divorce proceedings, particularly regarding dissipation of marital assets and, in covenant marriages, as a ground for dissolution.
How much does it cost to file for divorce in Arizona?
The filing fee for divorce in Maricopa County is $349 as of April 2026. Verify with your local clerk. Other counties may have slightly different fees. The responding spouse must also pay a fee to file a response. If you cannot afford court fees, you may petition for a fee waiver. Additional costs may include attorney fees, mediation costs, and expert witness fees in complex cases involving dissipation claims.
Can I file for divorce immediately after discovering adultery?
Yes, you can file for divorce at any time if you meet Arizona's 90-day residency requirement under A.R.S. § 25-312. You do not need to prove adultery or wait any specific period after discovering an affair. For standard marriages, simply asserting the marriage is irretrievably broken is sufficient. For covenant marriages, you would need to prove the adultery occurred to use it as your ground for divorce.
