Does Arizona have common law marriage? No, and it has not for over a century. Arizona abolished common law marriage back in 1913, making it one of the earliest states to eliminate this type of union.
Whether you are living together in Phoenix, Tucson, Scottsdale, or Mesa, simply cohabiting with a partner does not make you legally married under Arizona law in 2026. Knowing your legal standing today can protect your property, finances, and family rights.
What Is Common Law Marriage?
Common law marriage is a legally recognized union where two people live together, intend to be married, and present themselves publicly as a married couple without obtaining a formal marriage license or holding a ceremony.
While a small number of U.S. states still allow this arrangement, Arizona is not one of them and has not been for well over 100 years.
Does Arizona Recognize Common Law Marriage in 2026?
Arizona does not allow couples to form a common law marriage within the state. Under Arizona law, a valid marriage requires a marriage license issued by an Arizona county clerk and a formal solemnization. No amount of time spent living together as a couple creates a legal marriage in Arizona.
Does Arizona Recognize Out-of-State Common Law Marriages?
This is a critical exception that many Arizona residents overlook. If you formed a valid common law marriage in a state that legally recognized it, such as Texas, Colorado, or Iowa, and then moved to Arizona, the state will generally honor that union under the full faith and credit principle.
You should keep thorough documentation of your marital status, including joint tax returns, shared financial records, and any legal agreements, before asserting marital rights in Arizona courts.
Legal Rights for Unmarried Couples in Arizona
Because Arizona does not recognize common law marriage formed in-state, unmarried couples living together have very limited automatic legal protections. This affects several key areas:
- Property division when a relationship ends, since Arizona community property rules do not apply to unmarried couples
- Inheritance rights if a partner dies without a valid will
- Healthcare decision-making rights during a medical emergency
- Parental rights and child custody arrangements for shared children
How to Protect Your Relationship Legally in Arizona
Unmarried couples in Arizona can take important steps to safeguard their rights, including:
- Drafting a cohabitation agreement outlining property ownership and financial responsibilities
- Creating a legally valid will to protect your partner’s inheritance rights
- Assigning a durable power of attorney and healthcare directive to your partner
- Jointly titling shared property and bank accounts
How to Get Legally Married in Arizona
If you want full legal protections as a couple, the most reliable path is to obtain a marriage license through your local Arizona county clerk’s office. There is no residency requirement, and the process is straightforward and affordable for any couple ready to formalize their relationship.
Should You Consult an Arizona Family Law Attorney?
If you recently moved to Arizona with a common law spouse from another state, or if you are an unmarried couple dealing with property or custody disputes, speaking with a licensed Arizona family law attorney is the most important step you can take to fully understand and protect your legal rights.
