If you’ve lived with someone for 10 or 15 years, you may have heard people say that you’re basically common law married. Perhaps you own a house together or maybe one of you supported
0:08
the other while they built a career or raised children together. If the relationship ends, it’s reasonable to wonder whether or not Washington treats you in much the same way as a married
0:17
couple. The answer is more complicated than you might expect, but let me explain. Washington doesn’t recognize common law marriage simply because
0:24
you’ve lived together for a certain amount of time. But it does recognize something called a committed intimate relationship, usually shortened to CIR.
0:32
If your relationship qualifies, that can have a significant effect on what happens to property you’ve accumulated together. A CIR is a concept less than a
0:41
relationship status that helps courts frame how assets are divided after a long cohabitating relationship. The starting point isn’t really how long
0:49
you’ve lived together. It’s how you’ve lived together.
1:01
One of the biggest misconceptions about unmarried relationships is that you become common law married by default after a certain number of years. This
1:09
video isn’t related to every state in the union. We’re talking about Washington, and that doesn’t happen here. You could live together for 20 years and still not be legally married.
1:18
A committed intimate relationship is something a little bit different. It’s a legal doctrine Washington courts developed to deal with the financial reality of some long-term unmarried
1:27
relationships. For example, if you take two people who have lived together for 15 years and operated financially as a family out of one bank account, but one
1:35
person’s name happens to be on most of the assets, if they separate, the fact that they weren’t married doesn’t necessarily mean the person simply keeps
1:43
everything. Courts understand that relationships are messy and complicated and a formal marriage doesn’t always exist and there are policy interests in making sure those two people can
1:51
separate cleanly. If that cohabitation turns out to be a committed intimate relationship, then property acquired through the couple’s efforts during the relationship may be treated differently.
2:01
One of the big goals of CIRS is to make sure that both spouses can live independently later on while having an eye towards equity, not just cutting
2:10
everything in half. That being said, there are some significant differences between CIRs and marriages, even if one is found.
2:19
There isn’t a single test that automatically determines whether a relationship qualifies as a CIR. It’s really more of a set of squishy factors.
2:27
Washington courts look at the relationship as a whole. How long did you live together? What did you hold yourself out as publicly to other couples and business associates? Were
2:35
you building a shared life? Did you have joint bank accounts or separated ones, for example? You don’t necessarily need all these things. It might instead be
2:43
that one person paid the mortgage while the other covered most of the household expenses, but both can document what they contributed to the property and to
2:51
the common household, even if they weren’t married. The court can also look at the way you planned your future together. Naming each other as beneficiaries on insurance policies or
3:00
making other long-term financial decisions together may help show that the kind of CIR you had is one that a court would want to get involved in. But
3:08
to be clear, no individual fact decides these sorts of cases. It’s really a holistic analysis, and that’s sort of what makes them so challenging to deal
3:16
with in court. No two cases are ever alike. That’s why two couples who live together for exactly the same number of years could have very different outcomes
3:23
in court. A Washington court is trying to understand the substance of the relationship rather than simply counting how long it lasted.
3:33
The biggest point of conflict in a CIR is usually whose name is on the house.
3:38
This is where CIR law becomes really financially significant. Suppose you and your partner bought a house while you were together, but only their name appears on the title. You both lived
3:47
there for years and your combined finances supported the household, the mortgage, and the expenses. When the relationship ends, however, you shouldn’t necessarily assume that the
3:55
name on the deed answers every question about equity and where the value of that house goes. If the property was acquired during a CIR through the couple’s
4:02
efforts, it may be treated as community-like property and considered for equitable distribution to the parties. The same principle can potentially affect other property accumulated during the relationship.
4:12
Anything from cash assets to retirements. The important thing to focus on is how and when the asset was acquired. If you’re leaving a long
4:20
unmarried relationship, don’t assume you have no financial interest simply because an asset isn’t in your name.
4:25
Equally, having your name on an asset doesn’t necessarily mean the analysis ends there. The financial history really matters.
4:35
Property that existed before the relationship raises a very different question. A CIR doesn’t give your former partner interest in everything you own
4:42
beforehand. But over a long enough relationship, the position can become complicated. You may have already owned your home when your partner moved in, for example. But 15 years later, money
4:51
earned during the relationship has helped pay down the mortgage. And the two of you have contributed to the property’s upkeep and upgrading together with joint finances. You now need to
5:00
work out what part of that value relates to the property you originally brought into the relationship and whether the relationship developed an interest in some of the value created thereafter.
5:09
That’s where tracing income becomes really important. Old mortgage statements or records of improvements may suddenly really matter. And in a
5:17
relationship that lasted 20 years, reconstructing that financial history can take some work. The clearer the records are, the easier it is to
5:24
understand where the value actually came from and therefore what’s worth fighting over.
5:31
Although there are some similarities, the distinction is important because CIR law doesn’t give unmarried partners every right available to married
5:39
spouses. One significant example is spousal maintenance. In a divorce, a Washington court can consider whether maintenance should be paid to one spouse
5:47
after the marriage ends, usually to give them support or to maintain a lifestyle.
5:51
A pure CIR claim, however, doesn’t give the court that same authority simply because there’s a large difference between the former partner’s incomes. In
5:59
a CIR, to be clear, spousal maintenance will never be awarded. Someone may have spent years away from their career while
6:06
their partner’s earning capacity increased. They may have genuine claims relating to property accumulated during the C, but they shouldn’t assume that means they’ll also receive the kind of
6:15
ongoing maintenance that might have been available following a marriage. So although CR can produce outcomes in real property or other assets that sometimes
6:24
look and feel similar to divorce in some areas, the two legal relationships aren’t interchangeable.
6:32
Cir primarily deal with the economic relationship between adults. It does not determine parenting plans or parenting
6:39
issues. If unmarried parents separate, questions about where the children will live, if they have any, and how major decisions are made are dealt with
6:47
separately under Washington’s parenting plan laws. Child support is also dealt with separately as well. That means you can have two legal issues happening at
6:55
the same time in parallel. There may be a dispute about whether the adults had a CIR and how their property should be divided. And at the same time, there may
7:03
be decisions to make about children and childare. The fact that you weren’t married doesn’t automatically give either parent a better claim to the children. The good news or the bad news
7:11
depending on how you look at it is that Washington doesn’t recognize any difference between CIR parents, married parents, unmarried parents, any of the
7:19
above. If you are a parent of a child, then you’re a parent of the child and everyone deals with those parenting questions the same way at the same time
7:26
using the same court process. The court deals with these parenting questions separately and spoiler alert, the standard is best interest of the children, which we’ve talked about at length in other videos.
7:39
Now, CIRS can sometimes become relevant even when a couple eventually married.
7:44
You may have lived together for 10 years and then were married for three. If you looked only at the marriage certificate, you’d describe that as a three-year marriage. But financially, the relationship is actually a layer cake.
7:54
first a CIR for the many first years of the relationship and then a formal marriage until the end. If the period before marriage qualifies as a CIR, that
8:03
earlier history may matter when the court considers property accumulated over the course of the relationship.
8:08
Short marriages are usually treated very differently than longer relationships.
8:11
So, a CIR can have implications even during a divorce. This can be particularly important if substantial wealth was created before the wedding.
8:18
So, when you’re explaining the history of your relationship to your lawyer, don’t necessarily begin with the date you got married, the years before the wedding may be legally relevant, too.
8:30
If there’s a dispute about whether a CR existed, there probably isn’t going to be one document that sort of blows the whole case open. The evidence is usually
8:39
much more ordinary. It might be the way you paid for your home or the financial arrangements you made together or if you had a joint bank account. Perhaps you named each other as beneficiaries on
8:48
accounts or policies. And maybe you never opened a joint account, but for years you divided the household expenses between you and your partner in a
8:55
consistent way. The court is effectively looking backwards and trying to understand the substance of how a relationship functioned. That’s why documents that seemed unimportant at the time can later become very useful.
9:06
There’s also something couples can do before this ever becomes an issue. A cohabitation agreement, which you might have heard of, can set out how you
9:13
intend to deal with property while you’re together, but before you’re married, and what should happen if the relationship eventually ends. That can
9:21
be particularly useful when one person already owns substantial assets. But if the relationship has already ended, the immediate job is to understand the
9:29
history. How did you organize your finances? What property did you acquire while you were together? What did each of you contribute to the life you built?
9:37
Because while Washington doesn’t recognize common law marriages, unlike some other states, and a committed intimate relationship doesn’t give unmarried couples every legal protection
9:44
that marriage does, the absence of a marriage certificate doesn’t necessarily mean the absence of a legal consequence.
9:51
If you spent years building a shared economic life with somebody, the law may recognize that reality when the relationship ends. So, don’t assume you have no interest in an asset simply
9:59
because your name isn’t on it. And don’t assume that having your name on the title means the asset is automatically yours alone. This is why having an attorney to assess these issues is so
10:08
vitally important. And our number one advice when looking at these videos is find an advocate you trust. Because in a CIR, understanding how the two of you
10:16
actually lived is often the key to understanding what your options are moving forward.

In Seattle, it is incredibly common for couples to build a life, purchase real estate, and intertwine their finances over many years without ever signing a marriage license. You might share a mortgage, have children, and support each other’s careers just like a married couple. But what happens if the relationship ends?
Many unmarried individuals operate under a dangerous misconception. They assume that if their name is not on the deed to the house, or if the retirement accounts are solely in their partner’s name, they have no legal rights and must walk away with nothing. Conversely, the partner whose name is on all the assets often assumes they get to keep everything.
In Washington State, neither of these assumptions is automatically true.
Washington does not have “common-law marriage,” but it does recognize Committed Intimate Relationships (CIR). If a judge determines that your relationship qualifies as a CIR, the wealth you built together during that time will be divided almost exactly as if you had been legally married.
At Hemmat Law, we understand that untangling a long-term, unmarried relationship requires sophisticated legal analysis. Proving (or disproving) the existence of a CIR can be the difference between financial ruin and a secure future.
This guide explains how Washington courts define a Committed Intimate Relationship, how property is divided, what rights you do (and do not) have, and how to protect yourself during a separation.
A Committed Intimate Relationship is a legal doctrine created by the Washington State Supreme Court. It was designed to achieve equity. The courts recognized that it is fundamentally unfair for two people to function as an economic unit for years, only for one person to walk away with all the assets simply because their name happened to be on the title.
When a court declares that a CIR existed, it effectively treats the relationship like a marriage for the sole purpose of dividing the property and debt acquired during the timeframe the couple lived together.
Note: In older Washington case law, you may see a CIR referred to as a “meretricious relationship.” The courts updated the terminology to Committed Intimate Relationship to remove the negative, outdated connotations of the older term.
How does a judge know if you were just roommates who dated, or if you were in a Committed Intimate Relationship? Because there is no marriage certificate, the court must look at the behavior of the couple.
Under the landmark Washington Supreme Court case Connell v. Francisco, judges evaluate five specific factors. No single factor is decisive, and they are weighed together.
1. Continuous Cohabitation
You must have lived together continuously. If you maintained separate residences, or if you frequently broke up and moved into separate apartments for months at a time, it is much harder to prove a CIR existed.
2. Duration of the Relationship
There is no absolute minimum time requirement. However, King County courts rarely find a CIR in relationships lasting less than two to three years. Most CIR cases involve couples who have cohabitated for five to ten years or more. The longer you lived together, the stronger the presumption of a CIR.
3. Purpose of the Relationship
The court looks at whether the relationship was intended to include companionship, friendship, love, sex, and mutual support. Did you function as a family unit? Did you attend family events together, go on vacations, and hold yourselves out to the public as a couple?There is no absolute minimum time requirement. However, King County courts rarely find a CIR in relationships lasting less than two to three years. Most CIR cases involve couples who have cohabitated for five to ten years or more. The longer you lived together, the stronger the presumption of a CIR.
4. Pooling of Resources and Services
This is often the most heavily weighted factor. The court wants to see an intertwined economic life.
If you kept your finances strictly separate, split every dinner bill exactly 50/50, and never paid for each other’s expenses, it weighs heavily against finding a CIR.
5. Intent of the Parties
Did you intend to build a life together? The court will look at evidence such as naming each other as beneficiaries on life insurance policies or 401(k)s, drafting wills that leave assets to one another, or getting engaged.
If a judge rules that your relationship meets the criteria for a CIR, the next step is dividing the estate. This is where the process looks nearly identical to a traditional divorce.
Dividing “Community-Like” Property
In a marriage, assets acquired during the union are “community property.” In a CIR, assets acquired during the cohabitation are treated as “community-like” property.
The court will take all the property and debt accumulated during the CIR and divide it in a “just and equitable” manner. This usually means a 50/50 split, though a judge can deviate from that if fairness requires it. Common assets divided include:
Protecting Separate Property
Just like in a divorce, separate property remains separate. If you owned a house before the CIR began, the house itself is your separate property.
However, if your partner contributed to the mortgage payments for ten years using their income, or if they spent weekends remodeling the kitchen, the “community” may have established an equitable lien on the home. Your partner could be entitled to a portion of the home’s appreciation in value. Untangling commingled separate and community-like property in a CIR requires meticulous forensic tracing.
While a CIR provides significant property rights, it does not grant you the full spectrum of legal rights associated with marriage. Understanding these limitations is critical for your financial planning.
This is the single most significant difference between a CIR and a divorce. Washington courts do not have the legal authority to award spousal maintenance at the end of a CIR.
If you were a stay-at-home parent for 15 years while your unmarried partner built a lucrative tech career, you are entitled to half of the assets acquired during those 15 years. However, you cannot ask the court to order your partner to pay you monthly support to help you get back on your feet.
In a divorce, a judge can order the higher-earning spouse to pay the legal fees of the lower-earning spouse to ensure a fair fight. In a pure CIR case, the court generally does not have the statutory authority to award attorney’s fees based strictly on financial need. (Note: If child custody is also being litigated, fees can sometimes be awarded under the Uniform Parentage Act).
A Committed Intimate Relationship only dictates how property and debt are divided. It has nothing to do with children.
If you and your unmarried partner share children, those issues are governed by the Washington Uniform Parentage Act.
When unmarried parents separate, we simply file a Petition to Establish a Parenting Plan alongside a Petition to Divide Property (the CIR claim). The court handles them concurrently.
Many Seattle couples live together for a decade before finally deciding to get married. If they file for divorce three years later, is it a three-year marriage or a thirteen-year relationship?
In Washington, if a CIR transitions directly into a legal marriage, the court can “tack” the two timelines together.
This is incredibly strategic. A three-year marriage is a “short-term” marriage. In a short-term marriage, a court is unlikely to award spousal maintenance, and property division focuses on putting the parties back to where they were before the marriage. By proving a CIR existed for the ten years prior to the wedding, we transform the case into a long-term, 13-year economic partnership, significantly altering the division of real estate, retirement accounts, and potential spousal support awards.
If you are moving in with a partner in Seattle, you can proactively opt out of the CIR doctrine. Washington law allows couples to sign a Cohabitation Agreement (essentially a prenuptial agreement for unmarried couples).
A well-drafted Cohabitation Agreement dictates exactly what will happen if you separate. It can state that:
If you are a high-earner or own property, a Cohabitation Agreement is the most effective way to protect your wealth from future CIR litigation.
1. Assuming Moving Out Forfeits Your Rights: Rights don’t vanish when you leave.
Do not assume that because your name isn’t on the lease or the mortgage, you must walk away with nothing if you leave the shared home. If a CIR existed, you have a claim to the equity built during the relationship, regardless of where you currently sleep.
2. Relying Solely on the Deed: Titles do not dictate equity.
If your partner bought a house during your 8-year relationship, but only put their name on the title to get a better interest rate, do not assume they own it 100%. Under a CIR, you likely have a right to half the equity acquired during those 8 years.
3. Waiting Too Long to File a Claim: Statute of Limitations.
In Washington, you generally have a maximum of three years from the end of the relationship to file a legal claim for property division under a CIR. If you wait too long, your legal rights expire permanently.
4. Ignoring the Risks of Moving In: Get a Cohabitation Agreement.
If you are bringing substantial wealth, RSUs, or real estate into a new cohabitation arrangement, failing to sign a Cohabitation Agreement exposes your separate property to complex, expensive litigation if you break up five years later.
No. Washington State does not recognize common-law marriage. If you move to Washington, you cannot simply declare yourselves married. A CIR does not make you legally married; it is an equitable tool used solely by judges to fairly divide property when you break up.
There is no statutory minimum. While courts rarely recognize CIRs under three years, they look at the whole picture. A couple who lived together for three years, bought a house together, and had a child is much more likely to have a CIR than a couple who lived together for five years but kept all finances strictly separated.
No. Washington courts cannot award spousal maintenance (alimony/palimony) at the end of a CIR. This applies even if you gave up your career to support your partner.
If a judge determines a CIR existed, yes. The house will be treated as community-like property, and you are entitled to an equitable share of the equity built during the relationship, even if you are not on the title.
In Washington, pets are legally considered personal property. If you bought or adopted the pet during the CIR, it is community-like property. The judge will decide who gets the pet based on fairness, often looking at who the primary caretaker was.
Yes, absolutely. The CIR doctrine is fully gender-neutral and has been heavily used by LGBTQ couples in Washington, particularly to divide property acquired before same-sex marriage was legally recognized.
Any funds contributed to a 401(k), IRA, or pension during the timeframe of the CIR are considered community-like property and are subject to division.
Proving a CIR can be expensive because it requires presenting substantial evidence of your daily lives and financial interdependence. If your partner denies the CIR existed, you must go through formal discovery and trial, which costs tens of thousands of dollars.
Yes. Just like a divorce, you can and should attempt to mediate the division of your assets. With the help of attorneys and a neutral mediator, you can negotiate a property settlement agreement without ever going to trial.
No. This is a crucial distinction. A CIR only applies if the relationship ends in separation. If your partner dies without a will, Washington’s intestacy laws apply. Because you were not legally married, you inherit nothing. Unmarried couples must execute wills to protect one another.
To prove the end of a CIR, you must show the relationship is irretrievably broken. Continuing to live in the same house complicates this. The court will look at whether you moved into separate bedrooms, stopped sharing meals, and separated your finances to determine the exact date the CIR ended.
Yes. Once the relationship ends, you cannot remain on their employer-sponsored health insurance. Furthermore, unlike a legal marriage, you do not have the right to COBRA continuation coverage through their employer after a CIR ends.
Yes. If neither party can afford to buy out the other’s equity share, the judge can order the shared home to be sold and the net proceeds divided equitably.
If the debt was incurred during the CIR for the benefit of the relationship (e.g., buying furniture, groceries, or a shared vacation), it is considered community-like debt, and the court may assign a portion of it to you.
In a CIR dispute, the court often holds a bifurcated (two-part) trial. Phase one is a status hearing, where the judge only decides if a CIR existed. If the judge says yes, the case moves to phase two, where the property is actually divided.
Not necessarily. While joint accounts are strong evidence, a judge will look at how you functioned practically. If you had separate accounts but one of you paid the rent and the other paid all the bills and groceries, you still pooled your resources.
Washington courts apply Washington law to property located here, or to relationships that occurred here. If you lived together in a state that does not recognize CIR-type claims and then moved to Seattle, jurisdiction can become highly complicated.
Evidence of intent includes text messages discussing your future together, being listed as an emergency contact, drafting estate planning documents together, attending couples counseling, or buying engagement rings.
You generally have three years from the date the relationship ended to file a lawsuit to divide the property under the CIR doctrine.
Yes. Unlike a standard divorce where the forms are somewhat standardized, filing a CIR requires drafting custom legal complaints (a “Complaint for Division of Property in a Committed Intimate Relationship“). It is a highly nuanced area of law where unrepresented individuals frequently make fatal procedural errors.
