If you are separating from your partner without being married, you are likely wondering, “How is property divided for unmarried couples in Washington?” This is an especially important question for couples who share significant property, such as real estate, financial accounts, or debts.
While Washington has several divorce laws that outline the property division process between married couples, it looks different for couples who are not married. Unmarried couples are not automatically entitled to community property protections. Instead, how property is divided depends on the nature of the relationship, whether it can be classified as a committed intimate relationship, and the ownership of specific assets.
How Property Division Is Different for Unmarried Couples
When a married couple divorces in Washington, property acquired during the marriage is typically divided equitably between both spouses, while assets acquired before the marriage are kept separate. This is not necessarily the same for unmarried couples. Unmarried couples do not follow the property division laws that married ones do and can’t define community versus separate property depending on when a marriage took place.
Rather than following traditional property division laws, you and your partner must find another way to settle a property division case, which is why many couples explore cohabitation and property agreements to define ownership from the start. This is often done through thorough analysis of your assets and then settling on a division plan, though it can also be done by establishing a committed intimate relationship, which can provide an outline on how to divide assets.
Understanding Committed Intimate Relationships in Washington
A committed intimate relationship in Washington is a long-term, marriage-like relationship between an unmarried couple that carries specific legal implications during a separation. In 2025, there were 253 committed intimate relationship case filings in Washington. These cases are handled in the Washington Superior Court, such as the Benton County Superior Court at 7122 W. Okanogan Pl, Kennewick.
While there are no specific minimum qualifications for this type of relationship, the court evaluates the specific facts of each case to determine whether you are in a committed intimate relationship. They may look at several different factors to characterize your relationship.
If a committed intimate relationship is established, it can provide property rights to both partners. Assets acquired during the relationship may be divided equitably, similar to how assets acquired during a marriage are divided equitably during a divorce.
Assets to Consider During a Property Division Case
Whether you are looking to establish a committed intimate relationship for the property division protections or are simply trying to reach an agreement with your partner, it is important that you take care to properly identify and value each asset. You should also determine whether the asset was acquired during or before the relationship, and whether it should be kept separate. Property commonly involved in an unmarried property division case includes:
- Real estate. Homes and other real estate are often some of the most valuable assets, with the average home in Washington costing $603,870. Nine percent of all homebuyers are unmarried couples. Purchase agreements, deeds, and mortgage payments are all examples of relevant evidence when determining ownership and considering how to divide this asset.
- Financial accounts. Bank accounts or investment accounts may also be subject to division, especially when both people contributed to their value.
- Vehicles and personal property. Shared personal property, such as vehicles, electronics, furniture, and other items, can be difficult to divide because not only does it have monetary value, but it often carries sentimental or practical value.
- Business interests. Dividing business interests is particularly complex because they are difficult to value and can generate income.
A fair property division plan can be difficult to achieve, particularly if you and your partner disagree over key issues, such as the value of a certain asset or who owns a specific asset. It is essential to hire a property division lawyer who can guide negotiations based on factual evidence, helping you reach a mutually agreeable solution.
Why You Should Hire a Property Division Lawyer
Property division is never simple, even if a couple is married. For unmarried couples, it can be overwhelming to navigate the complicated property division laws and legal requirements, especially if you are also trying to establish your committed intimate relationship. On top of this, many people feel stress due to the significant financial implications that property division decisions have on their future.
A Washington property division attorney can walk you through each step of your case, helping you handle complex issues with the court or disputes with your partner. Throughout your case, your lawyer is an advocate who can also manage the legal requirements and deadlines of your case.
When it comes to establishing a committed intimate relationship, it is important to work with a lawyer to build a case that proves that your relationship qualifies. A lawyer can gather and present evidence to the court that supports that your relationship was long-term, continuous, and marriage-like. This is often through evidence of shared leases, property deeds, mortgage payments, personal expense records, or witness testimony.
A lawyer can also help you handle conflicts effectively, so they don’t get in the way of creating an equitable property division plan. A lawyer may speak with your spouse, act as a mediator, offer suggestions on potential solutions, and negotiate for a mutually favorable outcome. A lawyer can also foster a positive, collaborative environment early on, minimizing the risks of any major conflicts.
