What Is a Committed Intimate Relationship, and Can My Ex Claim My Property Without Marriage?

Washington does not have common-law marriage, so many couples assume that living together, even for years, gives neither partner any claim on the other's property if they split up. That assumption is wrong. Washington recognizes something called a committed intimate relationship, and when one exists, a court can divide property the couple acquired together even though they never married. For unmarried couples in Snohomish County, this doctrine can come as a genuine surprise. This topic is part of Washington divorce, custody, and support law.

A Doctrine Built by the Courts

The committed intimate relationship, often shortened to CIR, is not found in a statute. It is a doctrine Washington courts developed through case law to deal fairly with couples who lived together like spouses and built a life together without marrying. The Washington Supreme Court laid the groundwork in In re Marriage of Lindsey, 101 Wn.2d 299 (1984), holding that courts should examine these relationships and make a just and equitable division of the property the couple accumulated. The court refined the rule in Connell v. Francisco, 127 Wn.2d 339 (1995), and later adopted the modern name "committed intimate relationship" in Olver v. Fowler, 161 Wn.2d 655 (2007).

The point of the doctrine is to prevent an unfair result. Without it, when an unmarried couple separated, whoever held title to an asset would simply keep it, even if both partners had contributed to acquiring it. Washington courts decided that was inequitable, and the CIR doctrine is the remedy.

What Makes a Relationship a CIR

There is no checklist that automatically creates a committed intimate relationship, and no minimum number of years. Instead, courts look at the whole picture. Under Connell, the relevant factors include continuous cohabitation, the duration of the relationship, the purpose of the relationship, the pooling of resources and services for joint projects, and the intent of the parties. No single factor is decisive, and the list is not exclusive.

In practical terms, a court is asking whether this was a marriage-like relationship: a couple living together continuously over a meaningful period, sharing finances and a life, with the intent and conduct of committed partners. A brief or casual arrangement will not qualify. A long-term relationship where two people lived together, combined their money, bought things together, and functioned as a family unit is the kind of relationship the doctrine is designed to reach.

What a Court Can, and Cannot, Divide

This is where people are most often caught off guard, in both directions. If a court finds a committed intimate relationship existed, it does not divide everything either partner owns. Under Connell, the court divides only the property that would have been characterized as community property had the couple been married, meaning, generally, the property they acquired during the relationship through their efforts. The court makes a just and equitable distribution of that property, and there is a rebuttable presumption that property acquired during the relationship belongs to both partners.

Property that would have been separate is treated differently. Under Connell, property that a partner owned before the relationship began, or acquired during it by gift or inheritance, is generally not before the court for division. So your ex cannot simply lay claim to the house you owned before you met, or the inheritance your grandmother left you, merely because the relationship qualified as a CIR. The doctrine reaches the jointly built property, not each partner's separate property.

The Crucial Limits: A CIR Is Not a Marriage

It is essential to understand what the committed intimate relationship doctrine does not do, because it is not a backdoor to marriage. The courts have been clear that a CIR is not a marriage, and the marriage statutes do not directly apply.

Two consequences follow that matter enormously. First, there is no spousal maintenance. Washington's maintenance statute applies to spouses and registered domestic partners, not to CIR partners, so a former partner cannot obtain ongoing support the way a divorcing spouse might. The remedy in a CIR case is a division of the jointly acquired property, not alimony. Second, CIR partners do not inherit from each other automatically. Washington's intestate succession laws pass property to a surviving spouse and blood relatives, not to an unmarried partner. If one partner dies without a will, the survivor has no automatic right to inherit, although, as the Olver case recognized, the survivor may still pursue their share of the community-like property accumulated during the relationship as a claim against the estate. The difference between dividing jointly built property and inheriting as an heir is significant.

Why This Matters for Unmarried Couples

The takeaway cuts in two directions, and both are worth taking seriously. If you are the partner who entered the relationship with more assets or higher earnings, understand that property you and your partner build together can be divided if the relationship ends, even though you never married. And if you are the partner who contributed to a shared life without your name on the titles, understand that you may have a real claim to a fair share of what the two of you accumulated, rather than walking away with nothing.

Because the CIR doctrine is fact-intensive and built on case law rather than a clear statutory formula, these cases turn heavily on the specific history of the relationship and how the property was acquired and held. Couples who want certainty can address property expectations directly, through a written agreement, rather than leaving it to a court to reconstruct later.
