Does Oregon have common law marriage? No, it does not. Oregon does not allow couples to form a common law marriage within the state. Whether you are in Portland, Eugene, or Salem, no amount of cohabitation creates a legal marriage without a license and ceremony.
What Is Common Law Marriage?
Common law marriage is a union formed without a marriage license or ceremony. In states that recognize it, a couple can be considered legally married based on mutual agreement, cohabitation, and how they present themselves publicly. Oregon is not one of those states.
The Oregon Common Law Marriage 7-Year Rule Is a Myth
Many Oregon residents believe that living together for seven years automatically creates a legal marriage. This is false. There is no 7-year rule in Oregon law. No set period of cohabitation creates a common law marriage in Oregon, no matter how long the couple has lived together or how they hold themselves out publicly.
Does Oregon Recognize Common Law Marriage From Another State?
Yes, with one important exception. Oregon will recognize a valid common law marriage legally established in another state. According to the Oregon State Bar, if a couple meets the requirements of the state where their relationship was formed, Oregon will treat that marriage as valid when they relocate here.
So if you established a recognized common law marriage in Texas, Colorado, or Kansas and then moved to Portland or Bend, Oregon, the courts will honor that union.
Legal Options for Unmarried Couples in Oregon
Since Oregon does not allow common law marriage, unmarried couples have no automatic legal protections. Cohabitation alone does not give you property rights, inheritance rights, or authority to make medical decisions for your partner. Oregon offers two strong legal alternatives.
Oregon Registered Domestic Partnership
Under Oregon Revised Statute 106.310, any two adults aged 18 or older can register a domestic partnership with a county clerk’s office. Since January 2024, this option is open to couples of any gender.
A registered domestic partnership grants rights that mirror marriage, including joint state tax filing, healthcare decision-making, automatic inheritance without a will, and property dissolution rights if the relationship ends.
Oregon Cohabitation Agreement
A cohabitation agreement is a legally binding contract between two unmarried partners. It covers property ownership, shared finances, and what happens if the relationship ends or a partner dies. Oregon courts enforce these agreements under contract law.
Estate Planning Documents
Unmarried Oregon couples should also create a will, a healthcare directive, and a durable power of attorney. Without these documents, your partner has no automatic legal authority over your medical care or estate.
Talk to an Oregon Family Law Attorney
If you have questions about your legal standing, consult a family law attorney in Portland, Eugene, or Bend. Whether you need a cohabitation agreement, a domestic partnership registration, or guidance on an out-of-state common law marriage, professional legal advice protects your rights.
