Common Law Marriage in Arkansas: Legal Requirements and Exceptions

When a couple lives together for years without formalizing their relationship, they may wonder whether they have legal rights similar to married spouses.

In Arkansas, the concept of common law marriage is strictly limited. Understanding what is and isn’t recognized by the law can help couples protect themselves legally and financially.

Is Common Law Marriage Legal in Arkansas?

No. Arkansas does not recognize common law marriage formed within the state.

That means cohabiting partners—regardless of duration or presentation—are not considered legally married unless they go through the formal marriage process with a license and ceremony.

Historical & Legal Context

Arkansas formally abolished recognition of common law or de facto marriages in the mid‑20th century. Supreme Court cases have reaffirmed this status: cohabitation alone—even if the couple introduces each other as husband and wife—does not create a marriage.

The law requires official solemnization through a licensed officiant and proper filing.

Recognition of Valid Out‑of‑State Common Law Marriages

Although Arkansas doesn’t permit new common law marriages, it will recognize those legally established in other states where such unions are allowed.

Thanks to the U.S. Constitution’s Full Faith and Credit Clause, Arkansas treats valid out-of-state common law marriages as if they were traditional marriages.

To maintain the status in Arkansas, couples must demonstrate that:

• They met the legal criteria in their previous state (such as mutual intent, cohabitation, and public representation),
• They have not dissolved the relationship, and
• They can provide evidence like joint financial documents, shared property titles, or sworn affidavits.

Legal Implications for Cohabiting Couples

• No automatic inheritance rights: Without a legal marriage, a surviving partner has no claim under intestate succession laws unless named in a will.
• Separate property default: Assets remain individually owned unless formally titled together or governed by a cohabitation agreement.
• No spousal support or alimony: In separation, no mandatory financial support arises from cohabitation.
• Limited decision-making authority: Without legal documentation, a partner may not have rights to medical decisions or hospital visitation.
• Tax filing status: Cohabiting individuals cannot file jointly for taxes unless legally married.

Legal Alternatives & Planning Tools

Unmarried couples in Arkansas can protect their rights using several legal tools:

• Cohabitation Agreements: Written contracts outlining how assets, debts, and responsibilities are handled, including provisions for separation or death.
• Estate Planning Documents: Wills, powers of attorney, and beneficiary designations can help unmarried partners gain some protections of married couples.
• Joint Ownership: Listing both partners as joint tenants or having survivorship benefits in property or accounts offers some legal safeguards.

Final Thoughts

Arkansas does not allow couples to establish common law marriages within the state. However, valid common law unions from other states may still be recognized—a key exception.

For couples living together in Arkansas, legal tools like cohabitation agreements, estate planning, and joint property arrangements offer methods to protect rights.

For the full rights and protections comparable to marriage, formal legal marriage is encouraged.
