Meta description: Learn whether polygamy is legal in Arizona, how the state’s bigamy law works, what exceptions may apply, and what penalties and family-law consequences can follow.
Polygamy—the practice of having more than one spouse at the same time—is not legally recognized in Arizona. State law prohibits plural marriages and makes knowingly marrying another person while a current spouse is still living a felony. However, the legal analysis depends on what happened: a plural marriage ceremony, an existing legal marriage, and an unmarried multi-partner relationship are not automatically the same thing under Arizona law. The distinction can affect criminal exposure, marital status, property rights, and family-court proceedings.
Is Polygamy Legal in Arizona?
No. Arizona prohibits polygamous or plural marriage. Article XX, Section 2 of the Arizona Constitution states that polygamous or plural marriages are “forever prohibited.” Arizona’s bigamy statute also makes it a crime for a person who has a living spouse to knowingly marry someone else. The state does not create multiple simultaneous legal marriages simply because people hold a religious ceremony or describe themselves as married.
In everyday use, “polygamy” often refers broadly to a relationship involving more than two partners. The legal term bigamy generally concerns a person entering a second marriage while a prior marriage remains in effect. Arizona’s criminal law focuses on knowingly marrying another person despite having a living spouse, rather than on every form of nonexclusive relationship.
The state’s constitutional rule and criminal statute address marriage. They do not mean that every adult relationship involving multiple consenting partners automatically constitutes bigamy. Whether conduct violates a law depends on the facts, including whether a person was already legally married and whether the person knowingly entered another marriage.
Arizona’s Bigamy Law
Arizona Revised Statutes § 13-3606 provides that a person with a living spouse who knowingly marries another person is guilty of bigamy, a Class 5 felony. The statute’s central elements are therefore an existing living spouse, a subsequent marriage, and knowledge that the prior spouse is living. The precise application can depend on the circumstances and available evidence.
A second ceremony may raise questions even if the person does not obtain a second marriage license or the second union is later ruled invalid. A ceremony, the parties’ intentions, and the legal status of the first marriage may all be relevant. The fact that a second marriage is not valid does not by itself answer whether a crime occurred; criminal liability must be assessed under the statute and the evidence.
By contrast, a person who is legally divorced or whose prior marriage has been annulled is generally free to marry again, subject to other legal requirements. A separation, informal breakup, or agreement to live apart does not end a marriage. Until a court enters a divorce or annulment decree, the parties generally remain legally married.
Exceptions and Defenses Can Depend on the Facts
Arizona law includes limited circumstances relevant to a bigamy charge. Under A.R.S. § 13-3607, a person may have a defense when the person reasonably believes the former spouse is dead, or when the former spouse has been absent and not known to be living for five successive years. The statute also addresses a marriage that has been dissolved or declared invalid by a court.
These are not blanket permissions to enter another marriage. For example, a long period of separation alone does not necessarily establish that a spouse is dead or satisfy the statutory conditions. Whether a belief was reasonable, how long a person was absent, and what the person knew can require close examination of records, communications, and other evidence.
A defense is also different from an automatic finding that no crime occurred. A person facing a possible bigamy investigation should not assume that a missing spouse, an overseas ceremony, or an informal divorce arrangement resolves the issue. A lawyer can review the marriage and court records and determine how the statutes may apply.
What Penalties Can Apply?
Bigamy is a Class 5 felony in Arizona. A felony conviction can have consequences beyond any sentence imposed by a judge, including a criminal record and potential effects on employment, professional licensing, housing, and immigration matters. The specific sentence depends on the person’s circumstances, criminal history, and the facts of the case.
Arizona felony sentencing is governed by statutes that distinguish among first-time, repetitive, and other cases. It is therefore not accurate to assume that every Class 5 felony results in the same sentence. A court may consider the applicable sentencing range and other legal factors. Anyone seeking case-specific guidance should consult an Arizona criminal-defense attorney rather than relying on a general online summary.
A person may also face family-law complications even without a bigamy conviction. A disputed second marriage can affect decisions about inheritance, property, benefits, and the legal rights of partners. The outcome may depend on whether a valid first marriage existed, where a ceremony took place, and what documents were signed.
Does Arizona Criminalize an Unmarried Multi-Partner Relationship?
Not every relationship involving more than two adults is bigamy. The bigamy statute concerns knowingly entering another marriage while already having a living spouse. A relationship in which adults are not legally married to multiple people is not automatically a plural marriage under that statute merely because the partners live together or call one another spouses.
That distinction does not make every related arrangement legally consequence-free. Issues can arise under other laws or in specific situations—for example, if someone makes a false statement on an official form, disputes arise over jointly owned property, or a court must decide parentage or support. A person’s use of the word “married” does not necessarily establish a legal marriage, and the details matter.
Arizona has also historically had a criminal statute concerning adultery, A.R.S. § 13-1408. That statute is separate from bigamy and should not be treated as equivalent to a prohibition on all nonmonogamous relationships. The fact that a law appears in the code does not settle how it applies to a particular situation; an attorney can advise on current law and practical enforcement.
Are Religious or Spiritual Plural Marriages Recognized?
A religious or spiritual ceremony may be meaningful to the people involved, but it does not authorize a second civil marriage in Arizona. If a person is already legally married, another ceremony does not create an additional Arizona-recognized spouse. It may, depending on the circumstances, become relevant to a bigamy investigation.
Similarly, a group’s religious beliefs do not override state marriage law. Arizona’s constitutional prohibition applies to polygamous and plural marriages, and the bigamy statute can apply when its elements are met. The legal question is not simply whether a ceremony was religious, but whether a person knowingly entered a marriage while already having a living spouse.
What About a Plural Marriage Performed Outside Arizona?
A ceremony outside Arizona does not automatically make a plural marriage valid in the state. Arizona generally recognizes many marriages validly entered in another jurisdiction, but that principle does not mean a person can use an out-of-state ceremony to bypass Arizona’s prohibition on plural marriage or its bigamy law. Recognition questions can be complex, particularly when the ceremony took place in another country or the parties’ legal circumstances changed over time.
Arizona law on recognition of marriages performed elsewhere is addressed in part by A.R.S. § 25-112. The statute provides a general rule for marriages valid where contracted, subject to legal limits. Because plural marriage is specifically prohibited in Arizona, anyone relying on an out-of-state or foreign plural marriage should obtain individual legal advice before making decisions about divorce, inheritance, benefits, or property.
Can Someone Have More Than One Spouse for Immigration or Benefits?
Calling multiple people spouses does not generally give each person the legal rights associated with a spouse under Arizona law. A person cannot assume that every partner will qualify as a spouse for inheritance, health insurance, Social Security, tax filing, or employment benefits. Each program has its own eligibility rules, and legal marital status is often central to the analysis.
Plural-marriage questions can also create immigration concerns. Immigration rules and the facts of a case may affect whether a marriage can support an immigration benefit. A person should not submit forms describing a relationship as a legal marriage without confirming that the marriage is valid for the purpose at issue. An immigration lawyer can assess the relevant federal rules alongside Arizona law.
Property, Inheritance, and Family-Law Issues
When a person has multiple partners, legal rights may not match the partners’ expectations. A partner who is not a legal spouse may not automatically receive a spouse’s inheritance share or have authority to make medical decisions. Joint ownership, beneficiary designations, contracts, and estate-planning documents can help address some concerns, but they do not turn an invalid plural marriage into a valid one.
Arizona is a community-property state for many matters involving valid marriages. If a claimed second marriage is invalid, a court may need to determine which marriage is legally recognized and how property should be classified. That analysis can involve dates, marriage certificates, divorce decrees, financial records, and the circumstances surrounding each relationship.
Parents’ relationship status does not by itself determine a child’s legal rights. Parentage, custody, and child support are handled under separate rules. Adults involved in a complex family arrangement may benefit from legal advice about parentage, estate planning, and property ownership even when no criminal charge is pending.
Practical Steps if a Marriage Is Unclear
- Obtain official records: Collect marriage certificates, divorce decrees, annulment orders, and relevant court documents.
- Confirm the legal status of the first marriage: Separation or an agreement between partners is not a substitute for a final divorce or annulment.
- Avoid another marriage ceremony until status is confirmed: A second ceremony can create legal and criminal risks if a prior marriage remains in effect.
- Get advice before signing forms: Insurance, tax, immigration, and benefit documents may require accurate information about marital status.
- Consult the appropriate attorney: A criminal-defense lawyer can assess potential charges, while a family-law or estate-planning lawyer can address marriage, property, and family rights.

Arizona Laws and Reliable Resources
The primary sources for Arizona’s rules include Article XX, Section 2 of the Arizona Constitution, which prohibits plural marriages, and Arizona Revised Statutes § 13-3606, which defines bigamy and classifies it as a Class 5 felony. A.R.S. § 13-3607 describes specified defenses, while A.R.S. § 25-112 addresses recognition of marriages contracted elsewhere.
Statutes provide the general rules, but they cannot resolve every case. The validity of a prior marriage, the details of a later ceremony, a person’s knowledge, and the availability of a statutory defense can all matter. Because bigamy is a felony and family rights may be affected, anyone with a specific concern should have the documents reviewed by an Arizona attorney.
