Arizona law provides two distinct legal pathways for ending a marriage: annulment and divorce (dissolution of marriage). Under A.R.S. § 25-301, Arizona courts may declare a marriage null and void when specific impediments render the marriage invalid from its inception. Divorce, governed by A.R.S. § 25-312, terminates a valid marriage. The critical difference is that annulment treats the marriage as though it never legally existed, while divorce acknowledges and ends a valid union. Filing fees in Arizona range from $266 to $360 depending on your county and whether minor children are involved. Both proceedings require at least one spouse to have been domiciled in Arizona for a minimum of 90 days before filing.
| Key Facts | Arizona Annulment | Arizona Divorce |
|---|---|---|
| Filing Fee | $266-$360 (varies by county) | $266-$360 (varies by county) |
| Waiting Period | None specified | 60 days mandatory |
| Residency Requirement | 90 days | 90 days |
| Grounds Required | Yes (void/voidable) | No (no-fault state) |
| Property Division | Community property rules apply | Community property rules apply |
| Spousal Maintenance | Generally not available | Available if eligible |
| Legal Effect | Marriage declared never existed | Valid marriage terminated |
What Is the Difference Between Annulment and Divorce in Arizona?
An annulment in Arizona declares that a marriage was never legally valid, meaning the union is treated as though it never occurred from a legal standpoint. A divorce (dissolution of marriage) terminates a marriage that was legally valid. Under A.R.S. § 25-301, Arizona Superior Courts have the authority to adjudge a marriage null and void when the alleged cause constitutes an impediment rendering the marriage void. This distinction has significant implications for property division, spousal maintenance eligibility, and how individuals can legally describe their marital history. A person whose marriage is annulled can truthfully state they were never married, while a divorced person cannot make that claim.
The practical consequences of choosing annulment versus divorce extend beyond semantics. In Arizona, spousal maintenance (alimony) is typically unavailable in annulment proceedings because A.R.S. § 25-319 specifically addresses maintenance in dissolution of marriage or legal separation proceedings rather than annulments. However, under A.R.S. § 25-302, Arizona courts retain the power to divide assets and debts and issue child custody and support orders even when granting an annulment. This means children born during an annulled marriage are still considered legitimate, and parents remain financially responsible for their support.
Another key distinction involves the burden of proof. Arizona divorce requires no showing of fault since the state adopted no-fault divorce. Either spouse need only claim the marriage is irretrievably broken. Annulment, however, requires proving specific grounds that made the marriage void or voidable from its inception. This evidentiary burden makes annulment more challenging to obtain and often more time-consuming and expensive than an uncontested divorce.
What Are the Grounds for Annulment in Arizona?
Arizona recognizes two categories of marriages eligible for annulment: void marriages and voidable marriages. Void marriages are prohibited by law and considered invalid from the moment they occurred, regardless of whether either party seeks annulment. Voidable marriages are valid unless and until one party petitions for annulment and proves the grounds. Under Arizona law, grounds for annulment include bigamy, incest, fraud, duress, lack of mental capacity, intoxication at the time of marriage, underage marriage without proper consent, and concealment of impotence.
Void Marriages (Automatically Invalid)
Void marriages in Arizona violate fundamental legal prohibitions and are considered nullities from inception. Under A.R.S. § 25-101, Arizona prohibits marriages between parent and child, grandparent and grandchild of every degree, brother and sister of half or whole blood, uncle and niece, aunt and nephew, and first cousins. These incestuous marriages are automatically void and can be annulled at any time. Bigamous marriages, where one party enters a new marriage before legally dissolving a previous marriage, are similarly void under Arizona law. No time limit applies to seeking annulment of a void marriage, and either party or even a third party with standing may petition the court.
Voidable Marriages (Valid Until Annulled)
Voidable marriages require a court order to become invalid. Arizona courts recognize the following grounds for declaring a marriage voidable:
- Fraud or Misrepresentation: One spouse deceived the other about a crucial aspect of the marriage such as fertility, criminal history, or financial standing
- Duress or Coercion: One party was forced or compelled to marry under threat of violence or other pressure
- Lack of Mental Capacity: One party was insane, mentally ill, or otherwise incapacitated and unable to provide legal consent
- Intoxication: One party was so intoxicated at the time of the marriage ceremony that they lacked the intent to marry
- Underage Marriage: A party under 18 married without required parental consent, or a party under 16 married without both parental and Superior Court approval
- Concealment of Impotence: One party concealed their physical inability to consummate the marriage
For voidable marriages, the defrauded or injured party must act promptly after discovering the grounds for annulment. Continuing to live as married after learning of the defect may constitute ratification, which bars later annulment claims. Arizona courts have held that remaining in a voidable marriage after gaining knowledge of the basis for annulment demonstrates acceptance of the marriage.
How Do You File for Annulment in Arizona?
Filing for annulment in Arizona requires submitting a Petition for Annulment to the Superior Court in the county where you or your spouse resides. The filing fee ranges from $266 in Pima County to $360 in Maricopa County, as of March 2026. You must meet the 90-day residency requirement under A.R.S. § 25-312, meaning either you or your spouse must have been domiciled in Arizona for at least 90 consecutive days before filing. Once filed, you must serve your spouse with the petition unless you file jointly.
The annulment petition must clearly state the grounds for annulment and provide factual allegations supporting those grounds. Unlike divorce petitions where stating the marriage is irretrievably broken suffices, annulment petitions require specific evidence of fraud, duress, bigamy, incest, or other recognized grounds. You should include documentation supporting your claims, such as evidence of a prior undissolved marriage (for bigamy), medical records (for mental incapacity), or communications demonstrating fraud or coercion.
Step-by-Step Annulment Filing Process
- Confirm you meet the 90-day Arizona residency requirement
- Determine which grounds for annulment apply to your situation
- Gather evidence supporting your annulment grounds
- Complete the Petition for Annulment (available from your county Superior Court)
- File the petition with the Clerk of the Superior Court and pay the filing fee ($266-$360)
- Serve your spouse with the petition and summons (unless filing jointly)
- Wait for your spouse to respond (20 days if served in Arizona, 30 days if out of state)
- Attend any required hearings to present evidence of your grounds
- Obtain the court order declaring the marriage null and void
Unlike divorce, Arizona does not impose a mandatory 60-day waiting period for annulments. However, if your spouse contests the annulment or disputes your evidence, the process can take significantly longer than an uncontested divorce. Contested annulments may require discovery, depositions, and a trial, potentially extending the timeline to 6-12 months or longer.
How Does Arizona Divorce Work Compared to Annulment?
Arizona divorce (dissolution of marriage) terminates a legally valid marriage without requiring proof of wrongdoing by either spouse. Under A.R.S. § 25-312, Arizona is a no-fault divorce state, meaning the only ground required is that the marriage is irretrievably broken with no reasonable prospect of reconciliation. This contrasts sharply with annulment, which demands proof of specific defects that invalidated the marriage from its inception. The divorce process is generally more straightforward and predictable than pursuing an annulment.
Arizona Divorce Requirements
- Residency: At least one spouse must have been domiciled in Arizona for 90 days before filing
- Waiting Period: A mandatory 60-day cooling-off period under A.R.S. § 25-329 applies after service of process
- Filing Fee: $266-$360 depending on county (Maricopa County charges $349-$360; Pima County charges $266 without children or $311 with minor children)
- Grounds: Irretrievably broken marriage (no fault required)
- Service: The respondent must be served or sign an acceptance of service to start the 60-day clock
The minimum time to finalize an uncontested Arizona divorce is 61 days due to the mandatory waiting period. Most uncontested divorces take 90-120 days from filing to final decree. Contested divorces involving disputes over property, custody, or support can take 6-18 months or longer depending on complexity and court schedules.
Arizona offers a Summary Consent Decree option for couples who agree on all terms before filing. Both spouses sign and submit the petition and response together, and the 60-day waiting period begins on the filing date rather than the service date. This streamlined process represents the fastest path to divorce for fully cooperative couples.
How Is Property Divided in Annulment vs. Divorce?
Arizona is a community property state under A.R.S. § 25-211, meaning all property acquired during the marriage is presumed to be jointly owned by both spouses. Courts generally divide community property equally (50/50) in divorce proceedings, though A.R.S. § 25-318 allows for equitable distribution that may deviate from strict equality in certain circumstances. Separate property (assets owned before marriage, gifts, and inheritances) remains with the original owner unless commingled with community assets.
Despite annulment declaring the marriage never legally existed, A.R.S. § 25-302 explicitly authorizes Arizona courts to divide assets and debts in annulment proceedings. This means practical property division occurs regardless of whether you pursue annulment or divorce. Courts apply community property principles to assets acquired during the period the parties believed themselves married, ensuring fair distribution even when the marriage is declared void.
Property Division Comparison
| Factor | Annulment | Divorce |
|---|---|---|
| Community Property Division | Yes, under A.R.S. § 25-302 | Yes, under A.R.S. § 25-318 |
| Separate Property Protection | Yes | Yes |
| Debt Division | Yes, equitably divided | Yes, equitably divided |
| 50/50 Presumption | Generally applies | Generally applies |
| Marital Home | Subject to division | Subject to division |
| Retirement Accounts | Subject to division | Subject to division |
Is Spousal Maintenance Available in Annulment Cases?
Spousal maintenance (alimony) is generally not available in Arizona annulment cases because the marriage is declared to have never legally existed. Under A.R.S. § 25-319, spousal maintenance provisions apply to dissolution of marriage or legal separation proceedings, not annulments. This represents a significant disadvantage for financially dependent spouses seeking annulment rather than divorce. If one spouse requires financial support after the marriage ends, divorce may be the more practical option despite any preference for annulment.
In divorce cases, Arizona courts may award spousal maintenance when a spouse meets eligibility criteria under A.R.S. § 25-319. The spouse seeking maintenance must demonstrate at least one of the following: lack of sufficient property to meet reasonable needs, inability to be self-sufficient through employment, contribution as a homemaker, contribution to the other spouse's education or career, or advanced age or health conditions limiting employment ability. The 2022 amendments to Arizona spousal maintenance law introduced guidelines that courts use to calculate duration and amount, focusing on enabling the receiving spouse to become self-sufficient.
What About Children in Annulment vs. Divorce?
Children born during a marriage that is later annulled are considered legitimate under Arizona law, and both parents retain full parental rights and responsibilities. Under A.R.S. § 25-302, Arizona courts have explicit authority to issue child custody and child support orders when granting an annulment. This ensures children are protected regardless of whether their parents' marriage is dissolved through divorce or declared void through annulment. Child support calculations follow the same Arizona Child Support Guidelines in both proceedings.
Custody determinations in both annulment and divorce cases follow the best interests of the child standard. Arizona courts consider factors including each parent's relationship with the child, the child's adjustment to home and school, the mental and physical health of all parties, and any history of domestic violence. Under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), codified at A.R.S. § 25-1001, Arizona must be the child's home state for at least six consecutive months before the court can make initial custody determinations.
How Much Does Annulment vs. Divorce Cost in Arizona?
Arizona annulment and divorce filing fees are identical, ranging from $266 to $360 depending on your county and whether minor children are involved. Maricopa County (Phoenix) charges $349-$360 for a Petition for Dissolution or Annulment, while Pima County (Tucson) charges $266 without children or $311 with minor children. Additional costs include $50-$150 for service of process, $50 per parent for the mandatory Parent Information Program (required when minor children are involved), and certified copy fees of $0.50-$1.00 per page. As of March 2026, verify exact amounts with your local clerk as fees may change annually.
Cost Comparison Table
| Cost Category | Typical Range | Notes |
|---|---|---|
| Filing Fee (Maricopa County) | $349-$360 | As of March 2026 |
| Filing Fee (Pima County) | $266-$311 | Higher with children |
| Service of Process | $50-$150 | Sheriff or private process server |
| Parent Information Program | $50/parent | Required with minor children |
| Certified Copies | $0.50-$1.00/page | Multiple copies often needed |
| Attorney Fees (Uncontested) | $1,500-$5,000 | Varies significantly |
| Attorney Fees (Contested) | $5,000-$25,000+ | Complex cases cost more |
Annulments often cost more than uncontested divorces because they require proving specific grounds through evidence and testimony. Contested annulments involving disputes over whether grounds exist can become particularly expensive, with attorney fees potentially exceeding $25,000 in complex cases. Fee waivers are available for those whose household income falls at or below 125% of the federal poverty guidelines.
Should I Choose Annulment or Divorce in Arizona?
Choose annulment if you have provable grounds that made your marriage void or voidable from its inception and you want the legal declaration that the marriage never existed. This option makes sense when fraud, bigamy, incest, or other fundamental defects affected the marriage's validity. Some individuals prefer annulment for religious reasons, as certain faiths do not recognize divorce but may accept annulment. However, be prepared for a potentially more challenging legal process requiring evidence and testimony to prove your grounds.
Choose divorce when you had a legally valid marriage that you wish to end, when you cannot prove annulment grounds, or when you need access to spousal maintenance. Divorce is typically faster, less expensive, and more predictable than annulment. The no-fault framework means you need not prove wrongdoing or air private matters in court. Most Arizona couples end their marriages through divorce rather than annulment because meeting the specific annulment grounds proves difficult or impossible.
Decision Factors
- Timeline: Annulment has no waiting period but may take longer overall; divorce has a mandatory 60-day wait but is often faster total
- Cost: Annulment typically costs more due to evidentiary requirements
- Spousal Support: Generally unavailable in annulment; available in divorce if eligible
- Evidence Required: Annulment requires proving specific grounds; divorce requires only stating marriage is irretrievably broken
- Religious Considerations: Some faiths prefer annulment to divorce
- Legal Status: Annulment declares you were never married; divorce acknowledges marriage existed
Covenant Marriage Considerations in Arizona
Arizona is one of only three states (along with Louisiana and Arkansas) that offers covenant marriage under A.R.S. § 25-901. Couples who entered a covenant marriage agreed to premarital counseling and accepted more restrictive grounds for divorce. Under A.R.S. § 25-903, covenant marriage divorce requires proving fault grounds such as adultery, felony conviction, abandonment, physical or sexual abuse, or living separately for two years. The no-fault irretrievably broken standard does not apply to covenant marriages.
For covenant marriages, annulment may actually be easier to obtain than divorce if valid grounds exist. While covenant marriage restricts divorce grounds significantly, annulment grounds remain the same. A covenant marriage that was entered through fraud or duress can be annulled without satisfying the stricter divorce requirements. However, covenant marriages remain rare, representing less than 1% of Arizona marriages, so most couples face the choice between standard annulment and no-fault divorce.
Frequently Asked Questions
How long do I have to be married to get an annulment in Arizona?
Arizona has no time limit for seeking annulment of a void marriage such as bigamy or incest. For voidable marriages involving fraud, duress, or lack of capacity, you must act promptly after discovering the grounds. Courts may deny annulment if you continued living as married after learning of the defect, finding that you ratified the marriage. Generally, filing within months rather than years of discovery strengthens your case.
Can I get an annulment if my spouse committed adultery in Arizona?
No, adultery is not grounds for annulment in Arizona. Adultery occurs after a valid marriage is formed and does not render the marriage void or voidable from its inception. You would need to file for divorce rather than annulment. If you have a covenant marriage, adultery serves as a fault ground for divorce under A.R.S. § 25-903, but it still does not qualify for annulment.
Does an annulment affect child custody and support in Arizona?
No, annulment does not eliminate parental rights or responsibilities. Under A.R.S. § 25-302, Arizona courts retain full authority to issue child custody and support orders when granting an annulment. Children born during an annulled marriage remain legitimate, and both parents must support them according to Arizona Child Support Guidelines. Custody determinations follow the same best interests standard as divorce cases.
Is an Arizona annulment faster than divorce?
Not necessarily. While annulment has no mandatory 60-day waiting period, contested annulments often take longer than uncontested divorces. You must prove specific grounds for annulment, which requires gathering evidence and potentially conducting a trial. An uncontested divorce with both parties agreeing takes a minimum of 61 days and often completes within 90-120 days. Contested annulments can take 6-12 months or longer.
Can I get spousal support (alimony) if my marriage is annulled?
Generally no. Arizona spousal maintenance provisions under A.R.S. § 25-319 apply to dissolution of marriage and legal separation, not annulment. Because annulment declares the marriage never legally existed, courts typically cannot award spousal maintenance. If you depend on financial support from your spouse, divorce rather than annulment may better protect your interests.
What is the filing fee for annulment in Arizona in 2026?
Arizona annulment filing fees range from $266 to $360 depending on your county. Maricopa County (Phoenix) charges $349-$360, while Pima County (Tucson) charges $266 without minor children or $311 with children. Additional costs include service of process ($50-$150) and the Parent Information Program ($50 per parent when children are involved). Verify current amounts with your local Superior Court clerk as fees may change.
How do I prove fraud for an Arizona annulment?
To prove fraud for annulment, you must demonstrate that your spouse intentionally misrepresented or concealed a material fact essential to the marriage, that you reasonably relied on the misrepresentation, and that you would not have married had you known the truth. Examples include hiding a prior undissolved marriage, concealing criminal history, lying about fertility or intention to have children, or misrepresenting religious beliefs. Documentary evidence, communications, and witness testimony support fraud claims.
Do I need a lawyer for annulment in Arizona?
While not legally required, hiring an attorney is strongly recommended for annulment cases. Unlike no-fault divorce where you simply state the marriage is irretrievably broken, annulment requires proving specific legal grounds through evidence. An experienced family law attorney understands the evidentiary standards, can gather supporting documentation, and can present your case effectively in court. Self-representation risks dismissal if you fail to prove your grounds.
What happens to property if my Arizona marriage is annulled?
Arizona courts divide property in annulment cases using the same community property principles applied in divorce. Under A.R.S. § 25-302, courts have explicit authority to divide assets and debts when granting an annulment. Property acquired during the period you believed yourself married is typically divided equally (50/50), though courts may adjust distribution based on equitable factors. Separate property remains with its original owner.
Can a same-sex marriage be annulled in Arizona?
Yes, same-sex marriages are subject to the same annulment grounds as opposite-sex marriages following the Supreme Court's 2015 Obergefell v. Hodges decision. If your same-sex marriage involved fraud, bigamy, lack of consent, or other void or voidable grounds, you may petition for annulment. The 90-day residency requirement applies equally. Arizona law makes no distinction between same-sex and opposite-sex marriages for purposes of annulment or divorce.
