Common Law Marriage in Arizona: Legal Requirements and Exceptions

If you’ve lived with a partner in Arizona for several years and acted like a married couple, you might be wondering: Are we legally married under common law? This is a common question, especially among couples who share property or raise children together without a formal wedding.

Here’s everything you need to know about common law marriage in Arizona, including legal recognition, exceptions, and how to protect your rights.

Is Common Law Marriage Legal in Arizona?

No, Arizona does not allow couples to establish a common law marriage within the state. Simply living together and referring to one another as spouses is not enough to create a legally binding marriage under Arizona law.

To be legally married in Arizona, a couple must:

• Obtain a valid marriage license
• Participate in a recognized marriage ceremony conducted by an authorized officiant

Does Arizona Recognize Common Law Marriages from Other States?

Yes, Arizona will recognize a common law marriage if it was legally established in another state where common law marriage is valid.

For example, if you and your partner established a common law marriage in Texas, Colorado, or Iowa—states where such marriages are legally recognized—and then moved to Arizona, your marriage will still be considered valid.

To be recognized in Arizona, the common law marriage must meet the legal criteria of the originating state, such as:

• Mutual intent to be married
• Cohabitation
• Public acknowledgment as a married couple

Why This Matters Legally

If your out-of-state common law marriage is recognized in Arizona, you may be entitled to:

• Spousal rights (health benefits, inheritance, insurance)
• Marital property division in a divorce
• Survivorship rights in the event of a partner’s death

However, couples who lived together in Arizona without forming a legal marriage or moving from a common law marriage state will not have automatic spousal rights under Arizona law.

Legal Alternatives to Common Law Marriage in Arizona

If you’re in a long-term relationship and want legal protection, but don’t plan to get married, there are options available:

1. Cohabitation Agreement

A legal contract outlining how property, income, and responsibilities are handled during the relationship and in the event of separation.

2. Power of Attorney

Grants your partner legal authority to make healthcare or financial decisions on your behalf if you become incapacitated.

3. Wills and Estate Planning

Ensure your partner can inherit your property and assets if something happens to you.

These legal tools help protect unmarried couples in the absence of recognized marriage rights.

Final Thoughts

While Arizona does not allow common law marriages to be formed within its borders, the state does honor valid common law marriages from other jurisdictions. If you’re in a committed relationship and want to protect your rights, it’s wise to consider legal alternatives like cohabitation agreements or formal marriage.
