Common Law Marriage in Oregon: Is It Recognized? (2026)

Oregon does not recognize common law marriage. Oregon has never permitted couples to form a marriage without a license and solemnization ceremony. Two people who live together in Oregon for any length of time, regardless of how long or how they describe their relationship, do not acquire married status under Oregon law.

Does Oregon Recognize Common Law Marriage?

No. Oregon does not permit couples to form a new common law marriage, and it never has. Oregon law has consistently required a marriage license and a solemnization ceremony for a marriage to be valid.

The governing statute is ORS Chapter 106, which sets out the requirements for a valid Oregon marriage. Under ORS 106.010, marriage is a civil contract entered into in person by two people who are at least 18 years old and otherwise capable, and solemnized in accordance with ORS 106.150. ORS 106.041 requires a marriage license issued by the county clerk. ORS 106.150 requires the parties to declare their assent in the presence of someone authorized to solemnize marriages under ORS 106.120, such as a clergy member or a judge, and in the presence of at least two witnesses.

The printed text of ORS 106.010 still carries the older phrasing "males at least 18 years of age and females at least 18 years of age." That gendered limit is not enforceable. A federal court struck down Oregon's same-sex marriage ban in Geiger v. Kitzhaber, 994 F. Supp. 2d 1128 (D. Or. 2014), and the U.S. Supreme Court settled the question nationally in Obergefell v. Hodges, 576 U.S. 644 (2015). Oregon county clerks issue marriage licenses without regard to the sex of the applicants. The Multnomah County clerk, for example, lists only that each applicant is at least 18 years old, is not currently married, is not a first cousin or nearer of kin, will marry within 60 days, and will hold the ceremony in Oregon.

Oregon courts have consistently interpreted this statutory scheme to mean that no marriage arises without satisfying these requirements. There is no parallel common law path to marital status in Oregon. Oregon has never enacted a statute creating common law marriage, and Oregon courts have never developed a common law doctrine that would permit marriage formation outside the licensing and solemnization system.

This distinguishes Oregon from the small number of states, such as Colorado, Texas, and Iowa, that continue to recognize common law marriage today.

Oregon Has Never Recognized Common Law Marriage Formation

Some states abolished common law marriage at a specific cutoff date, meaning marriages formed before that date may still be valid. Oregon is not in that category.

Oregon never recognized common law marriage formation in the first place. There is no Oregon cutoff date because there was never a period during which Oregon allowed couples to form a common law marriage. A couple cannot point to an old Oregon court decision or a grandfathering rule to claim that their relationship constitutes an Oregon common law marriage.

This is an important distinction for anyone who has lived in Oregon for an extended period and hopes that longevity of cohabitation has created legal marital status. It has not. No length of time living together in Oregon creates a marriage.

The Seven-Year Rule Is a Myth

A widespread misconception holds that couples who live together for seven years, or some other fixed period, automatically become common law married. This is false in every state, including Oregon.

Oregon has no seven-year rule and no cohabitation rule of any kind that creates marriage. Because Oregon never recognized common law marriage formation at all, the question of how long cohabitation must last is simply irrelevant under Oregon law.

The myth likely persists because common law marriage was historically recognized in many states and people assume a nationwide standard exists. It does not. Each state sets its own rules, and Oregon's rule is clear: marriage requires a license and ceremony, full stop.

What Rights Do Unmarried Partners Have in Oregon?

Unmarried couples in Oregon do not have automatic legal rights against each other in the way that married spouses do. Specifically:

Property rights. Property that is titled in one partner's name belongs to that partner. There is no Oregon equivalent of the "committed intimate relationship" doctrine that Washington state uses to divide property between long-term unmarried cohabitants.

Inheritance. An unmarried partner has no automatic right to inherit from the other partner under Oregon's intestacy laws. ORS 112.025 and ORS 112.035 give an intestate share only to a surviving spouse, and ORS 112.045 passes the estate to the decedent's descendants, parents, siblings, or grandparents when there is no surviving spouse. Without a will, a trust, or a beneficiary designation naming the partner, a deceased partner's assets pass to those relatives rather than to the surviving partner.

Spousal support. Oregon spousal support (ORS Chapter 107) is available only to parties to a legal marriage. An unmarried partner cannot claim spousal support after the relationship ends.

Health care decisions. Oregon's health care representative statute (ORS Chapter 127) allows individuals to designate any trusted adult as their health care representative, but without a formal designation, the default hierarchy favors blood relatives over an unmarried partner.

Insurance and benefits. Employer-provided benefits and life insurance policies generally require a legal marriage or registered domestic partnership for spousal coverage, unless the employer has specifically extended benefits to unmarried partners.

Unmarried partners who want legal protections should address them proactively. Options include:

• A cohabitation agreement setting out how property and expenses are shared and what happens if the relationship ends
• Joint titling of real property as joint tenants with right of survivorship
• Beneficiary designations on retirement accounts, IRAs, and life insurance naming the partner
• A will or revocable trust
• A durable power of attorney for finances
• A health care representative designation under ORS Chapter 127

Oregon Domestic Partnerships

Oregon previously offered registered domestic partnerships for same-sex couples only, under the Oregon Family Fairness Act of 2007. Those partnerships provided state-law rights equivalent to marriage. Eligibility stayed limited to same-sex couples for nearly two decades. House Bill 2032 (2023 Regular Session) amended ORS 106.310 to open registered domestic partnerships to couples of any sex, effective January 1, 2024, giving opposite-sex couples in Oregon the same option same-sex couples already had.

A domestic partnership is a formal legal status. It is not the same as common law marriage. A domestic partnership must be registered with the state; it does not arise automatically from cohabitation.

Oregon Does Recognize Out-of-State Common Law Marriages

Although Oregon does not permit couples to form a common law marriage within Oregon, Oregon does recognize a common law marriage that was validly formed in another state.

This follows from the Full Faith and Credit Clause of the U.S. Constitution and from traditional conflict-of-laws comity principles. If a couple formed a valid common law marriage in Colorado, Texas, Iowa, Kansas, or another state that recognized common law marriage at the time of formation, Oregon courts will treat that marriage as valid when the couple moves to Oregon or otherwise becomes subject to Oregon jurisdiction.

For example, a couple that lived together in Colorado and satisfied Colorado's common law marriage requirements under In re Marriage of Hogsett, 2021 CO 5, has a recognized marriage in Oregon if they later relocate. That marriage was valid when formed in Colorado, and Oregon will give it full recognition.

The practical implications include:

• The couple may dissolve the marriage through Oregon divorce proceedings
• Spousal support (alimony) and property division rules apply
• The surviving spouse has inheritance rights under Oregon intestacy law
• Oregon courts have jurisdiction to enter child support and custody orders

If you may have formed a common law marriage elsewhere before moving here, have an Oregon family lawyer check whether that state's requirements were met in a free case evaluation (attorney advertising).

How an Out-of-State Common Law Marriage Ends in Oregon

A common law marriage recognized under another state's law and brought into Oregon ends only through formal divorce or dissolution proceedings. The process is identical to dissolving a ceremonial marriage under ORS Chapter 107.

There is no "common law divorce." The parties cannot simply agree to end the marriage or stop holding themselves out as married. Until a court enters a final judgment of dissolution, the marriage legally continues.

What rights do unmarried couples have in Oregon?

Unmarried partners in Oregon do not automatically have property rights, inheritance rights, or spousal support claims against each other. Oregon has no committed-intimate-relationship doctrine like Washington state.

How does a common law marriage end if the couple moves to Oregon?

Does Oregon have domestic partnerships?

Yes. Oregon offers registered domestic partnerships, which provide state-law rights equivalent to marriage. Unlike common law marriage, a domestic partnership must be formally registered with the state. It does not arise automatically from cohabitation, and it is a separate legal status from marriage.
