NO RING, NO RULES?
SPLITTING UP WITHOUT A MARRIAGE IN OREGON

The Short Answer: Oregon Law Treats You Like Strangers, Mostly

Many couples in Eugene live together for years, buy a house, share a dog, and raise children without ever marrying. When those relationships end, people are often surprised to learn that Oregon has no “divorce” for unmarried partners. Oregon does not let couples create a common-law marriage here, no matter how long they live together. Instead, the law handles the breakup in pieces: property under one set of rules, children under another, and support hardly at all.

The good news is that the rules for children are the same whether or not the parents were married. The harder news is that property and money issues depend heavily on what the two of you intended, and on what you can prove.

Registered vs. Unregistered: A Critical Difference

Oregon does offer a formal alternative to marriage. Under the Oregon Family Fairness Act, ORS 106.300 to 106.340, two adults (at least one of whom lives in Oregon) can file a Declaration of Domestic Partnership with the county clerk. A registered partnership carries the same rights and responsibilities as marriage under ORS 106.340, and ending one requires a court case much like a divorce, including property division and, where appropriate, spousal support.

This article is about everyone else: couples who called themselves “partners” but never registered. If you are not sure whether you registered, check with the county clerk where you lived before assuming either way.

How Property Is Divided When You Never Married

Oregon’s divorce statutes do not apply to unmarried couples. Since the Oregon Supreme Court’s decision in Beal v. Beal (1978), courts divide property acquired during a nonmarital relationship based on the express or implied intent of the partners. If you signed a written agreement, it usually controls. If you did not, the court looks at how you actually lived and handled money. Evidence that can show an intent to share includes:

• Joint checking or savings accounts and pooled paychecks
• Buying a home, vehicle, or other major assets together, and how title was taken
• Who paid the down payment, mortgage, and repairs
• Whether one partner stayed home, worked in the other’s business, or paid household bills so the other could build savings
• Statements to lenders, family, or friends about what was “ours”

These cases are filed as civil claims in circuit court rather than as a divorce, and they can be document-heavy. Our post on dividing the house and assets in an Oregon divorce explains how married couples split a home; for unmarried partners, the question is less about fairness and more about what you both agreed to, in writing or through your conduct.

Debts Follow the Signature

Debt works the same way it does for any two people who are not married. A credit card, car loan, or mortgage in one partner’s name is generally that partner’s debt. A joint loan lets the creditor collect from either of you, regardless of any private deal about who pays. Before you separate, pull your credit reports so you know exactly which accounts carry both names.

No Spousal Support, With Rare Exceptions

Oregon awards spousal support in marriage dissolution cases and, through the Family Fairness Act, to registered domestic partners. An unmarried partner generally cannot ask the court for ongoing support simply because the relationship ended, even after decades together and even if one partner gave up a career. The main exception is a contract: if you signed an enforceable agreement promising support, you may be able to enforce it as a contract claim.

Children: Same Rights as Married Parents, Once Parentage Is Set

Here the law is much kinder to unmarried families. ORS 109.060 says the legal relationship between parents and children is the same whether or not the parents were married. But there is a catch: an unmarried partner does not get the automatic presumption of parentage that a spouse gets under ORS 109.067. Parentage must be established, usually by signing a voluntary acknowledgment under ORS 109.070 or through a court or administrative order.

Once parentage is established, either parent can file a case under ORS 109.103 to set custody, parenting time, and support. The same best-interests factors in ORS 107.137 apply as in a divorce. Until a court enters an order, ORS 109.161 gives sole legal custody to the parent who had physical custody when parentage was established, which is why it pays to act early. Our child custody page and our post on custody vs. parenting time explain how those decisions are made.

Child support is calculated under the same Oregon guidelines used for married parents. Same-sex couples should be especially careful: if the non-birth partner was never a spouse or registered partner, they may need to take additional legal steps, such as an adoption or a court judgment of parentage, to secure their relationship with the child.

Protecting Yourself Now

• Put it in writing. A cohabitation agreement is the single best way to control what happens to property if you split up.
• Think about how you take title. How a deed or vehicle title is written matters.
• Establish parentage early. Don’t assume living together or being on the lease protects your rights as a parent.
• Consider whether registration or marriage fits your goals. If you do plan to marry, our post on Oregon prenuptial agreement requirements is a good place to start.
• Keep records. Save statements showing who paid for what, especially for a home.
