Love doesn’t always come with a marriage certificate. Many couples in Washington State choose to build their lives together without walking down the aisle, sharing homes, bank accounts, and decades of memories. But when death arrives unexpectedly, the legal reality can be devastating: without proper planning, your beloved partner may have no legal right to inherit anything from your estate.

Washington State’s inheritance laws make a stark distinction between married couples, registered domestic partners, and unmarried couples living together. While the law provides automatic inheritance rights for spouses and state registered domestic partners, unmarried partners—regardless of how long they’ve been together or how intertwined their lives have become—receive nothing under intestate succession laws.

This harsh reality has caught countless families off guard, leaving surviving partners not only grieving but also potentially homeless and financially devastated. The good news? With proper estate planning, unmarried couples can secure their partner’s future and ensure their wishes are honored.

Who Gets What When There’s No Will in Washington State?

When someone dies without a will in Washington, the state’s intestate succession laws found in RCW 11.04.015 determine who inherits their property. The law creates a specific hierarchy of inheritance that prioritizes legal relationships over emotional ones.

Under Washington’s intestate succession statute, surviving spouses or state registered domestic partners receive all of the decedent’s share of the net community estate. Additionally, they receive varying portions of separate property depending on whether the deceased had children or living parents.

The surviving spouse or state registered domestic partner will receive:

  • All community property
  • One-half of separate property if the deceased had children
  • Three-quarters of separate property if there were no children but living parents or siblings survive
  • All separate property if no children, parents, or siblings survive

For unmarried partners who aren’t state registered domestic partners, the answer is simple and devastating: nothing. The Washington Supreme Court has held that a surviving unmarried partner cannot be considered a surviving spouse under Washington’s intestate succession law.

What Exactly Is a State Registered Domestic Partnership?

Washington State recognizes state registered domestic partnerships, which provide inheritance rights similar to marriage. However, these partnerships have specific requirements and limitations that many couples don’t realize.

State registered domestic partners means two adults who meet the requirements for a valid state registered domestic partnership as established by RCW 26.60.030 and who have been issued a certificate of state registered domestic partnership by the secretary.

To qualify for state registered domestic partnership in Washington, couples must:

  1. Both be at least 18 years old
  2. Not be married or in another domestic partnership
  3. Not be related by blood closer than would prohibit marriage
  4. Share a common residence
  5. Declare their relationship as their domestic partnership

It’s important to note that simply living together, even for decades, doesn’t create a domestic partnership. The relationship must be formally registered with the state. Domestic partners are eligible for the right to inherit property from a partner and to administer the partner’s estate in the absence of a will.

Many couples assume that city or local domestic partnership registrations provide the same rights, but this isn’t always the case. Only state registered domestic partnerships receive full inheritance rights under Washington law.

Can Unmarried Partners Inherit Anything Without a Will?

The short answer is no—unmarried partners who aren’t state registered domestic partners cannot inherit through intestate succession in Washington State. This means that if your unmarried partner dies without a will, their property will pass to their blood relatives according to the state’s inheritance hierarchy, even if you’ve been together for decades and shared everything.

The property will typically go to:

  1. Children (biological or legally adopted)
  2. Parents
  3. Siblings and their descendants
  4. Grandparents
  5. Aunts, uncles, and cousins
  6. The state of Washington (if no relatives can be found)

This harsh reality has led to heartbreaking situations where surviving partners have been forced from homes they helped pay for, lost access to bank accounts they contributed to, and received nothing from estates they helped build.

The Washington Supreme Court has been clear on this issue. In denying claims by unmarried partners to be considered spouses under Washington’s intestate law, the state Supreme Court emphasized that “the division of property following termination of an unmarried cohabiting relationship is based on equity, contract or trust, and not on inheritance”.

How Can Unmarried Partners Protect Each Other?

While Washington’s intestate laws don’t protect unmarried partners, several legal tools can ensure your partner is provided for after your death. The key is taking action while you’re both alive and able to make these important decisions.

Wills and Testament Planning

The most straightforward way to provide for an unmarried partner is through a comprehensive will. A properly executed will allows you to leave your property to anyone you choose, regardless of your legal relationship with them. Each partner needs to execute dispositive documents: a Will or, in the alternative, a revocable living trust coupled with a pour-over Will.

Your will can specify exactly what you want your partner to receive, from specific items with sentimental value to your entire estate. Without this document, your partner has no automatic legal claim to your property.

Revocable Living Trusts

Living trusts offer additional benefits beyond a simple will. They allow property to pass to your partner without going through probate, which can save time, money, and privacy. Trust assets typically transfer more quickly than assets that must go through the probate process.

A revocable living trust also provides flexibility during your lifetime, allowing you to modify the terms if your circumstances change. This can be particularly valuable for unmarried couples whose relationships may evolve over time.

Joint Ownership Arrangements

Certain types of joint ownership can help ensure property passes to your partner automatically. Joint tenancy with right of survivorship means that when one owner dies, the surviving owner automatically receives full ownership of the property.

However, joint ownership isn’t appropriate for all situations and can create complications, particularly regarding taxes and creditor claims. It’s essential to work with an attorney to determine the best ownership structure for your specific circumstances.

Beneficiary Designations

Many assets pass outside of wills and intestate succession through beneficiary designations. These include:

  • Life insurance policies
  • Retirement accounts (401(k), IRA, etc.)
  • Bank accounts with payable-on-death provisions
  • Investment accounts with transfer-on-death designations

Regularly updating these beneficiary designations to include your partner is one of the simplest ways to ensure they receive these assets directly.

What About Community Property Rights?

Community property cannot exist without legal marriage. This is a significant disadvantage for unmarried couples in Washington, a community property state.

In marriage, community property laws generally mean that both spouses have equal ownership rights to property acquired during the marriage, regardless of who earned the income or whose name is on the title. This provides significant financial protection for both spouses.

Unmarried couples don’t receive these automatic protections. If you and your partner purchase a home together, for example, only the person whose name is on the deed has legal ownership rights unless you’ve created specific agreements to the contrary.

This makes written agreements particularly important for unmarried couples who are purchasing property together, starting businesses, or making other significant financial commitments.

Tax Implications for Unmarried Partners

Inheritance taxes can significantly impact what your partner actually receives from your estate. While married couples and state registered domestic partners enjoy certain tax advantages, unmarried partners typically don’t receive the same benefits.

For federal estate tax purposes, there’s no unlimited marital deduction for unmarried partners. However, given the current federal estate tax exemption amounts, this typically only affects very wealthy couples.

Washington State doesn’t currently impose a state inheritance tax on beneficiaries, regardless of their relationship to the deceased. However, the state does have an estate tax that applies to larger estates.

It’s also important to consider income tax implications. Inherited property typically receives a “stepped-up basis” for tax purposes, which can minimize capital gains taxes when the property is eventually sold. However, gifts made during your lifetime don’t receive this favorable treatment.

Common Mistakes Unmarried Couples Make

Many unmarried couples make assumptions about their legal rights that can prove costly. Here are some of the most dangerous misconceptions:

  • Assuming Common Law Marriage Rights: Washington State doesn’t recognize common law marriages, regardless of how long you’ve lived together or how married you appear to others. Living together for decades doesn’t create any automatic inheritance rights.
  • Believing City Domestic Partnerships Provide Full Rights: Local domestic partnerships don’t necessarily provide the same rights as state registered domestic partnerships. Only state registration provides full inheritance rights under Washington law.
  • Thinking Joint Bank Accounts Solve Everything: While joint accounts can provide access during your partner’s lifetime, they don’t necessarily provide inheritance rights to all property. Proper estate planning requires more comprehensive solutions.
  • Delaying Estate Planning: Many couples put off estate planning, thinking they have plenty of time. Unfortunately, accidents and unexpected illnesses don’t wait for convenient timing.
  • Not Updating Documents After Relationship Changes: If your relationship status changes—whether you marry, register as domestic partners, or separate—it’s crucial to update all estate planning documents and beneficiary designations.

Steps to Take Right Now

If you’re in an unmarried relationship in Washington State, don’t wait to protect your partner. Here are the essential steps you should take immediately:

  • Get Your Documents in Order: Ensure both you and your partner have current wills that reflect your wishes. These should be properly executed according to Washington State law to ensure they’re legally valid.
  • Review All Beneficiary Designations: Go through every account, insurance policy, and retirement plan to verify that beneficiary information is current and accurate.
  • Consider State Registered Domestic Partnership: If you’re eligible and it aligns with your goals, registering as state domestic partners can provide automatic inheritance rights similar to marriage.
  • Document Your Property Ownership: Keep clear records of what property belongs to whom and what you’ve purchased together. Written agreements can help prevent disputes later.
  • Plan for Incapacity Too: Estate planning isn’t just about death—you also need documents like powers of attorney and healthcare directives to protect each other if one of you becomes incapacitated.
  • Regular Review and Updates: Life changes, and your estate plan should change with it. Review and update your documents regularly, especially after major life events.

What Happens During Probate?

When someone dies in Washington State, their estate typically goes through probate—the legal process of settling their affairs. For unmarried partners, probate can be particularly challenging because they have no automatic legal standing in the proceedings.

If your unmarried partner dies with a will naming you as a beneficiary, you’ll likely receive your inheritance through the probate process. However, if there’s no will, you generally won’t have legal standing to participate in the probate proceedings, even if you believe you have a claim to some of the property.

The probate process can take months or even years, during which assets are typically frozen. This can create immediate financial hardship for surviving unmarried partners who depended on the deceased partner’s income or who need access to shared assets.

Having proper estate planning documents in place can help minimize probate complications and ensure your partner’s wishes are carried out efficiently.

Special Considerations for Same-Sex Couples

While same-sex marriage is now legal throughout the United States, some same-sex couples in Washington may still be in state registered domestic partnerships that were created before marriage equality. These couples have some important decisions to make.

State registered domestic partnerships provide inheritance rights, but marriage may offer additional federal benefits and protections. Couples should consider whether converting their domestic partnership to marriage makes sense for their situation.

It’s also worth noting that some couples may have legal documents or arrangements from before marriage equality that need updating to reflect current law and their current wishes.

Creating a Comprehensive Plan

Protecting an unmarried partner requires more than just a simple will. A comprehensive estate plan should address multiple scenarios and potential complications.

Your plan should consider what happens if:

  • You die first
  • Your partner dies first
  • You both die simultaneously
  • One of you becomes incapacitated
  • Your relationship ends
  • You have children from previous relationships
  • You acquire significant new assets

A well-designed plan will address all these possibilities and more, ensuring that your wishes are honored regardless of what the future brings.

Working with Professionals

Estate planning for unmarried couples can be complex, particularly when significant assets are involved or when there are children from previous relationships. Working with experienced professionals can help ensure your plan is comprehensive and legally sound.

An estate planning attorney can help you understand your options and create documents that reflect your specific situation and goals. They can also help you understand the tax implications of different strategies and ensure your documents comply with Washington State law.

Don’t try to handle complex estate planning on your own. The stakes are too high, and the law is too complicated for do-it-yourself solutions when significant assets or complex family situations are involved.

Key Takeaways

  • Unmarried partners have no automatic inheritance rights under Washington State law, regardless of how long they’ve been together or how committed their relationship is.
  • State registered domestic partnerships provide inheritance rights similar to marriage, but require formal registration with the state—simply living together doesn’t create these rights.
  • Proper estate planning is essential for unmarried couples who want to provide for each other, including wills, trusts, and beneficiary designations.
  • Community property laws don’t apply to unmarried couples, making written agreements and proper titling of assets particularly important.
  • Time is critical—estate planning should be completed while both partners are alive and able to make decisions about their future.

Frequently Asked Questions

Q: If we’ve lived together for 20 years, don’t we have common law marriage rights? A: No. Washington State doesn’t recognize common law marriages, regardless of how long you’ve lived together. You must be legally married or registered as state domestic partners to have automatic inheritance rights.

Q: We registered as domestic partners with our city. Does that give us inheritance rights? A: Not necessarily. Only state registered domestic partnerships provide full inheritance rights under Washington law. City or local registrations may not provide the same legal protections.

Q: Can my partner’s family challenge my inheritance if I’m named in their will? A: Family members can potentially contest a will, but simply being unmarried doesn’t make a will invalid. Properly executed wills that comply with Washington State law are generally upheld by courts.

Q: What if we own our house together but only one name is on the deed? A: Legal ownership typically follows the deed, regardless of who contributed to the purchase or mortgage payments. You may have other legal remedies, but inheritance law won’t automatically protect the partner not named on the deed.

Q: Should we get married just for the legal protections? A: Marriage does provide automatic legal protections that can simplify estate planning, but it’s a personal decision that should consider all aspects of your relationship. State registered domestic partnership may provide similar legal benefits if marriage isn’t right for you.

Q: What happens to our joint bank accounts if my partner dies? A: Joint accounts with right of survivorship typically pass to the surviving owner automatically. However, this doesn’t extend to other property, so comprehensive planning is still necessary.

Q: Can I inherit my partner’s retirement benefits? A: Only if you’re named as the beneficiary on the retirement account. Unlike spouses, unmarried partners don’t have automatic rights to retirement benefits, making beneficiary designations crucial.

Q: How much does estate planning cost for unmarried couples? A: Costs vary depending on the complexity of your situation and the documents needed. However, the cost of proper planning is typically far less than the potential financial devastation of not having a plan.
