More couples than ever are choosing to live together without getting married. In Poulsbo and across Kitsap County, this is increasingly common — whether by personal preference, financial circumstance, or simply because it felt like the right arrangement for the relationship. But when things fall apart, many of these couples are blindsided to discover just how different their legal situation is from that of a married couple.

If you are in a long-term relationship but never walked down the aisle, it is important to understand your rights — and your vulnerabilities — under Washington State law before a crisis forces the issue.

Washington Does Not Recognize Common Law Marriage

One of the most widespread misconceptions in family law is the idea that living together for a certain number of years automatically grants you the same rights as a married couple. This is not true in Washington State. Washington does not recognize common law marriage. No matter how long you have lived together, how many bills you share, or how intertwined your lives have become, the law does not treat you as married unless you actually are.

This has significant consequences when a relationship ends — particularly around property, finances, and parenting.

Property Rights for Unmarried Couples

In a divorce, Washington's community property laws provide a clear framework: assets and debts acquired during the marriage are generally divided equally. Unmarried couples have no such framework to fall back on.

When an unmarried couple separates, each person typically walks away with what is legally in their name. The house titled in one partner's name belongs to that partner. The savings account opened by one person stays with that person. Joint assets — property or accounts held in both names — will need to be divided, but without court oversight unless a dispute arises.

This can lead to deeply unfair outcomes, especially in long-term relationships where one partner may have contributed significantly to a home, a business, or a shared financial life without their name appearing on the paperwork. Washington courts can sometimes address these situations through legal doctrines like unjust enrichment or implied partnership, but these claims are difficult to prove and by no means guaranteed.

The clearest way to protect yourself is to put agreements in writing before problems arise. A cohabitation agreement — sometimes called a domestic partnership agreement — is a legally binding contract that outlines how property will be owned, how expenses will be shared, and what happens to assets if the relationship ends. Think of it as a prenuptial agreement for couples who are not getting married.

Financial Support After Separation

Unlike divorce, there is no legal framework in Washington that automatically entitles an unmarried partner to financial support after a separation. Alimony — or spousal maintenance — simply does not apply to unmarried couples.

If one partner gave up career opportunities, reduced their working hours, or became financially dependent on the other during the relationship, they may find themselves in a very difficult position after the split. There is no guaranteed legal remedy for this imbalance unless an enforceable agreement was made in advance.

This is another area where a cohabitation agreement can make a critical difference. If your relationship involves a significant financial imbalance, or if one partner has made sacrifices to support the household or the other partner's career, having an attorney draft a clear written agreement protects both of you.

Parenting Rights for Unmarried Couples

When unmarried couples have children together, the legal landscape shifts considerably. Washington State gives the same parenting rights and responsibilities to unmarried parents as it does to married ones — but only after paternity is legally established.

If the parents are not married at the time of the child's birth, the father does not automatically have legal parental rights simply by being named on the birth certificate. Paternity must be established either through a voluntary acknowledgment signed by both parents or through a court order. Until paternity is legally established, the mother has sole legal and physical custody by default.

Once paternity is confirmed, Washington courts treat unmarried parents exactly as they would divorcing spouses when it comes to custody and parenting plans. A parenting plan will be established outlining residential schedules, decision-making authority, and dispute resolution. Child support will be calculated based on both parents' incomes using Washington's standard formula.

It is worth noting that the courts do not favor one parent over the other based on marital status. The focus, as always, is on the best interests of the child.
