Oregon does not recognize common law marriage. No matter how many years you live together, share bills, or introduce each other as spouses, you are not legally married in Oregon without a license and a ceremony. State law requires both partners to apply for a marriage license through a county clerk and to declare their vows before an authorized officiant and at least two witnesses.1Oregon Public Law. Oregon Revised Statutes ORS 106.150 – Form of Solemnization; Witnesses Those steps are not optional. A couple who skips them simply is not married under Oregon law, whatever their intentions.
That leaves a real question for long-term partners: what protections do you actually have, and what do you need to put in place yourselves?
Property Rights When Unmarried Couples Separate
Because there is no marriage to dissolve, separating cohabitants do not get the divorce framework. There is no automatic presumption that assets acquired during the relationship belong to both of you, and there is no right to spousal support.2Justia. I Was Inquiring About Common Law Marriage in the State of Oregon
The Oregon Supreme Court’s 1978 decision in Beal v. Beal is the leading case. It directs courts to look at the couple’s actual intentions when dividing property accumulated during cohabitation.3Justia Law. Beal v. Beal – 1978 – Oregon Supreme Court Decisions Judges examine joint bank accounts, shared purchases, whose name is on the deed, and how the couple handled day-to-day finances. If the evidence shows a shared intent to co-own, the court can divide accordingly. The burden is on you to prove that intent. Married couples start with a presumption of shared ownership; unmarried couples have to build the case from scratch.
A written cohabitation agreement is the single most practical fix. Spell out who owns what, how you split expenses, and what happens if you break up. Oregon courts generally enforce these contracts when both partners signed voluntarily and the terms are clear.
Registered Domestic Partnerships
Oregon offers registered domestic partnerships as a legal status separate from marriage. Under the Oregon Family Fairness Act, a domestic partnership is a civil contract between two people who are at least 18, mentally capable of contracting, and where at least one partner is an Oregon resident.4Oregon Public Law. Oregon Revised Statutes ORS 106.310 – Definitions for ORS 106.300 to 106.340 As of January 1, 2024, partners may be of any sex.5Oregon Department of Revenue. Registered Domestic Partners
You register by filing a notarized Declaration of Oregon Registered Domestic Partnership with a county clerk. The state registration fee is $25, and some counties add processing fees on top.6Oregon Public Law. Oregon Revised Statutes ORS 106.330 – Registration Fee
Registered partners receive nearly all the state-law privileges, rights, and responsibilities of married spouses. That covers Oregon income tax treatment, inheritance rights involving children of either partner, and the same standing as a spouse in state court. Two carve-outs: benefits under Oregon’s public employee retirement system (ORS chapters 238 and 238A) and any employee benefit plan governed by the federal Employee Retirement Income Security Act are not required to extend to domestic partners.7Oregon State Legislature. Oregon Revised Statutes 106.340 – Certain Privileges, Immunities, Rights, Benefits and Responsibilities Granted or Imposed
Ending a partnership is not a matter of withdrawing the declaration. You must get a judgment of dissolution or annulment from an Oregon circuit court, the same as a divorce. By signing the declaration, both partners consent to Oregon jurisdiction for that proceeding even if one or both later move out of state.8Oregon State Legislature. Oregon Revised Statutes Chapter 106 – Marriage; Domestic Partnership You cannot enter a new partnership or marry someone else until that judgment is final.
Where Domestic Partnership Runs Out: Federal Law
The federal government does not treat registered domestic partners as married, and Oregon’s statute acknowledges that the legislature cannot control federal benefits.7Oregon State Legislature. Oregon Revised Statutes 106.340 – Certain Privileges, Immunities, Rights, Benefits and Responsibilities Granted or Imposed Four gaps matter most:
- Federal income tax. Registered domestic partners cannot file a joint federal return. Each partner files as single or, if eligible, head of household.9Internal Revenue Service. Answers to Frequently Asked Questions for Registered Domestic Partners and Individuals in Civil Unions
- Family and Medical Leave Act. The FMLA defines spouse under state marriage law, including recognized common law marriages. Domestic partners are excluded, so you cannot take FMLA leave to care for a seriously ill partner.10U.S. Department of Labor. Fact Sheet #28L – Leave Under the Family and Medical Leave Act When You and Your Spouse Work for the Same Employer
- Estate and gift tax. The unlimited marital deduction that lets spouses transfer assets to each other free of federal estate and gift tax does not apply. Transfers above the federal gift tax exclusion count against the lifetime exemption.
- Social Security. Survivor and spousal benefits go to legal spouses, including recognized common law spouses. Domestic partners do not qualify.
If federal benefits matter to your situation, marriage is the only status that provides them.
If Your Partner Dies Without a Will
Oregon’s intestate succession statutes only recognize a “surviving spouse.” An unmarried partner inherits nothing under those rules, no matter how long you were together. The estate passes to the deceased’s children, parents, or more distant relatives.11Oregon State Legislature. Oregon Revised Statutes Chapter 112 – Intestate Succession and Wills
A registered domestic partner is in a stronger position, because ORS 106.340 gives partners the same state-law rights as spouses, which should include treatment as a surviving spouse for intestacy.7Oregon State Legislature. Oregon Revised Statutes 106.340 – Certain Privileges, Immunities, Rights, Benefits and Responsibilities Granted or Imposed Even then, don’t rely on intestacy. A will, plus beneficiary designations on retirement accounts and life insurance and transfer-on-death or payable-on-death designations on bank accounts, sends assets to your partner directly and outside of probate.
Common Law Marriages From Other States
You cannot create a common law marriage in Oregon, but the state will recognize one you validly established somewhere else. About ten states still allow common law marriage, including Colorado, Iowa, Kansas, Montana, Texas, and Utah.12National Conference of State Legislatures. Common Law Marriage by State If you met the specific requirements of one of those states while you lived there, Oregon courts should treat you as legally married after you relocate.
Proving it is the hard part. There is no marriage certificate to show. Courts and agencies typically look for signed statements from both partners and blood relatives, joint mortgages or leases, shared bank accounts, insurance policies naming each other, and consistent use of the same last name.13Social Security Administration. Evidence of Common-Law Marriage If you think you have a valid out-of-state common law marriage and now live in Oregon, keep those records organized. Social Security in particular requires proof through signed statements and supporting documents.14Social Security Administration. Evidence of Common-Law Marriage
What Unmarried Oregon Couples Should Put in Writing
Without common law marriage, the legal safety net has to be built by the couple. Each of these documents fills a gap that marriage would otherwise close automatically.
- Cohabitation agreement. Spells out property ownership, expense sharing, and what happens to shared assets if you separate. Signed by both partners, ideally reviewed by an attorney.
- Wills. Without one, your partner has no inheritance rights at all. A basic will naming your partner as beneficiary is the floor.
- Beneficiary designations. Name your partner on life insurance, retirement accounts, and bank accounts with payable-on-death or transfer-on-death designations. These pass directly and skip probate.
- Healthcare power of attorney. Without one, your partner may have no legal authority to make medical decisions for you if you are incapacitated. Oregon hospitals are not required to defer to an unmarried partner absent a signed advance directive or power of attorney.
- Financial power of attorney. Lets your partner handle banking, bills, and other financial matters on your behalf if you cannot.
Long cohabitation alone does not make you married in Oregon, and it will not protect you when the relationship ends or one of you dies. The documents above, or a registered domestic partnership, or an actual marriage license, are what does.
