Common law marriage is not legal in Arizona, which means a couple can’t become married here just by living together, sharing a bank account, or telling friends they’re husband and wife. Arizona does, however, honor a common law marriage that was properly formed in a state that allows it, and that exception is where most of the real-world questions come from. A couple who moved from Texas or Colorado, for example, may already be married in Arizona’s eyes without ever having had a ceremony. This overview is general information, not legal advice, and an Arizona family law attorney can look at a specific situation.
The Rule for Couples Who Meet in Arizona
Arizona law requires two things to create a marriage inside the state: a marriage license and a ceremony performed by someone authorized to solemnize it. A couple who skips both has, legally speaking, a relationship but not a marriage, no matter how long it lasts.
- Living together for years doesn’t create a marriage
- Calling each other “husband” or “wife” doesn’t create one
- Sharing a last name, a lease, or a mortgage doesn’t create one
- Having children together doesn’t create one
Arizona’s courts have long treated this as settled. The state has no common law marriage doctrine of its own to apply.
The Out-of-State Exception
Arizona law provides that marriages valid where they were contracted are valid here, with limited public policy exceptions. That includes a common law marriage formed in a state that permits it.
An Arizona appellate decision, Grant v. Superior Court, shows how this works in practice. The court said Arizona doesn’t authorize common law marriage itself, but it gives a Texas common law marriage the same legal effect as one contracted in Arizona, and it asked whether the couple had actually satisfied Texas’s requirements.
So the question usually isn’t “Does Arizona allow it?” It’s “Did you meet the rules of the state where you say it happened?”
Which States Allow Common Law Marriage
A small group of states still let couples form a common law marriage today. The list commonly includes:
- Colorado
- Iowa
- Kansas
- Montana
- Rhode Island
- South Carolina
- Texas
- Utah, where the process involves a court or administrative step
- The District of Columbia
Other states once allowed common law marriage and still recognize ones formed before they ended it, with cutoff dates that differ widely. Alabama, for example, stopped allowing new ones as of January 1, 2017. This list changes over time, so confirm a particular state’s current rule before relying on it.
What It Takes to Form One in Those States
Requirements differ, but the core ideas are similar.
- Both people are free to marry, meaning no existing marriage and old enough under that state’s law
- Both agree to be married now, not someday
- They live together as spouses
- They present themselves to the community as married
Texas, for instance, lets couples either sign a declaration of informal marriage with the county clerk or satisfy the agreement, cohabitation, and holding-out elements. Details like that matter, which is why people who rely on this route often need a lawyer to prove it later.
Why Domicile and Timing Matter
Here’s a point many couples overlook. Moving to Arizona with an existing common law marriage is generally fine. What causes trouble is the reverse situation: an Arizona couple who take a short trip to a common law state and then claim they became married there.
Arizona residents who only pass through another state briefly may find that agencies, courts, or insurers question whether a real common law marriage was formed. Federal agencies, including the Social Security Administration, have their own rules for deciding whether a common law marriage counts, and domicile can be part of that analysis. The safest assumption is that a weekend visit isn’t a reliable way to create a marriage.
Why It Matters: What Marriage Controls
Whether a couple is legally married affects a long list of practical matters.
- Property: Arizona is a community property state, and community property rules apply only to a valid marriage
- Divorce: a court can divide property and set support only if a valid marriage exists
- Inheritance: a surviving spouse has automatic rights that an unmarried partner lacks
- Health care: spouses often have default authority to make medical decisions
- Benefits: health insurance, Social Security survivor benefits, and tax filing status depend on marital status
- Parentage: a husband is presumed to be the father of a child born during the marriage, while unmarried fathers may need to establish paternity
When two people assume they’re protected and aren’t, these gaps tend to surface at the worst possible time, such as during a hospital stay or after a death.
Protecting Yourselves If You’re Not Married
Unmarried couples in Arizona can still set up many protections on paper.
- Cohabitation agreement: a written contract covering property, bills, and what happens if you split up
- Wills: each partner can leave property to the other, since no automatic inheritance exists
- Beneficiary designations: update retirement accounts, life insurance, and bank accounts
- Healthcare power of attorney: names your partner to make medical decisions
- Financial power of attorney: covers money matters if you can’t act
- Joint ownership: title property carefully, with attention to survivorship rights
- Parentage steps: if you have children together, take the legal steps to establish parentage
These documents work best when they’re drafted before there’s a crisis.
Getting Legally Married in Arizona
Formalizing the relationship is straightforward.
- Both people apply together at the Clerk of the Superior Court, with valid ID
- Arizona has no waiting period after the license is issued, and the license stays valid for a year
- A judge, licensed clergy member, or other authorized officiant performs the ceremony
- The signed license is returned for recording
Fees and office hours vary by county, so check with the clerk’s office before going.
