Community property Washington rules decide what you can leave by will. See how agreements, Oregon moves, and titling affect your Vancouver, WA estate plan.
Married couples in Vancouver, Camas, and Washougal often assume a house or brokerage account belongs to whoever is named on the statement. Community property Washington rules look past the name on a deed or account. Most assets earned or purchased after marriage, or after registration of a state registered domestic partnership, are treated as owned by both people. That ownership is the starting point for any will, trust, or probate in Clark County, and it is the issue an estate planning attorney in Vancouver, WA sorts out before documents are drafted.
What is community property in Washington?
Community property is the default ownership for most assets a married couple or state registered domestic partners acquire after the relationship begins. Earnings during the marriage and assets purchased with those earnings are generally treated as community property, even when only one name appears on the title. Each spouse or domestic partner generally has an equal interest in that property.
Under RCW 26.16.030 (2026), property acquired after marriage or after registration of a state registered domestic partnership is community property unless it fits a separate-property category. Either spouse or either domestic partner may generally manage community property alone. That day-to-day power is narrower than people expect.
The same statute sets the hard stops:
- Neither person shall give community property without the express or implied consent of the other.
- Neither person shall sell, convey, or encumber community real property unless the other joins the deed or other instrument, and both must acknowledge it.
- Neither person shall purchase community real property unless the other joins the purchase.
- Household goods, furnishings, appliances, and a community mobile home generally require both signatures to sell or to create a non-purchase-money security interest.
- If both people participate in managing a business, neither may buy, sell, or encumber its assets or goodwill without the other's consent. If only one manages the business, that person may act in the ordinary course without the other.
In a typical Clark County closing, the title company will not insure a sale of the family home unless both spouses sign, even if the deed lists only one of you. That is the statute showing up in a conference room, not a lender preference. A joint checking account is different. One spouse can often write checks and pay bills. That is management, not a license to gift the account or retitle it as separate property.
What property stays separate after marriage?
Separate property is what you owned before marriage (or before a state registered domestic partnership) and what you later receive by gift, bequest, devise, descent, or inheritance, together with the rents, issues, and profits of that property. You may sell, encumber, or leave that property by will without your spouse joining. Mixing it with community funds is how that status is lost in practice.
RCW 26.16.010 (2026) states the rule for spouses. RCW 26.16.020 (2026) states the parallel rule for state registered domestic partners. Separate property is not subject to the other person's debts or contracts, and the owner may manage it as if unmarried.
As a hypothetical, suppose one spouse inherited funds from a parent, deposited them into the couple's joint checking account at a Vancouver branch, and then used the mixed balance to pay down a Hazel Dell mortgage. The inheritance started as separate property. After years of deposits and mortgage payments, proving what remains separate can require tracing that costs more than the dispute is worth. If you intend to keep an inheritance separate, hold it in an account titled only in your name and avoid paying community expenses from it.
| Community property | Separate property |
|---|---|
| Acquired after marriage or domestic partnership, unless it fits a separate-property category | Property brought into the marriage or domestic partnership |
| Gifts, bequests, devises, descents, and inheritances, plus their rents and profits | |
| The owner may devise the whole without the other person joining | |
| Both must join to sell or encumber community real property | The owner may sell or encumber without the other joining |
How do community property Washington rules limit your will?
You cannot give away the surviving spouse's interest, and a will that purports to leave the house to a child does not take that interest away.
Those limits include the will restriction in RCW 26.16.030 (2026). Homemade wills often ignore it. A parent tries to leave the Camas residence to children from a first marriage while the surviving spouse is still alive and still holds an equal interest. The will cannot deliver what the testator did not own.
Adult children who assumed they would inherit part of the family home are often surprised. That is one reason to read what happens if someone dies without a will before you rely on default law.
A revocable living trust does not expand what you own. You can pour only your interest into the trust. Funding a trust with community real property still requires both spouses to join the deed. Couples who want the survivor to have full control, or who want children protected if the survivor remarries, need coordinated documents, not a one-person trust sitting on top of community title.
Characterization can affect whether a return is due even when everything passes to the survivor. Community property can also receive a full income-tax basis adjustment at the first death, which is a reason some couples keep appreciated assets as community property rather than converting them to joint tenancy. Tax results depend on the asset and on federal law.
What does a Washington community property agreement do?
A community property agreement is a written contract both spouses or both domestic partners sign to set the status of property and direct what happens at death. Many Clark County couples use one so the survivor takes community assets without a probate of those assets. It must be executed with required formalities, and it does not wipe out creditor claims.
RCW 26.16.120 (2026) allows both spouses or both domestic partners to agree on the status or disposition of all or any portion of their community property, then owned or later acquired, to take effect at death. To be valid, the agreement must meet all of the following:
- Both people join in the agreement.
- Any later change uses the same formalities.
The statute is explicit that the agreement shall not derogate from the rights of creditors, and that the superior court may set it aside for fraud or on other equitable grounds. A short form signed at home without those formalities is not a reliable plan.
If the agreement is valid and covers the asset, that property often passes to the surviving spouse without a probate of the asset. Banks and title officers still ask for a death certificate and the agreement. For a house in Vancouver or Camas, couples typically record the agreement with the Clark County Auditor so the land records match the new ownership. Recording is about marketable title, not the only step that makes the agreement valid.
A community property agreement is one of several tools that can avoid probate. It is a poor fit for many second marriages. If the agreement converts everything to community property and leaves it all to the survivor, children of a prior relationship can be left with nothing from that estate. That problem shows up often in estate planning for blended families, and a later will that contradicts the agreement does not fix it.
How should couples with Oregon property plan in Washington?
Oregon is not a community property state. A couple that lives in Vancouver and owns a Portland rental, or that moved north from Multnomah County, can have two property systems in one household. Washington still reviews how marital earnings and assets of Washington residents should be classified. An Oregon deed does not automatically create separate property in a Washington estate plan.
Real property in Portland is conveyed under Oregon title rules. The money used to buy it may still be treated as community property if it came from wages earned while you were married and living in Washington. That split appears later, when someone has to decide what the decedent actually owned, or when a Washington will tries to leave "my Portland condo" as if one spouse owned it outright.
If you built retirement savings while living in Oregon and then relocated to Salmon Creek or Fisher's Landing, do not assume the old titling answers every Washington question at death. Review beneficiary designations, deeds, and any agreement you signed in Oregon. Oregon documents rarely use Washington community-property language, and a deed that worked in Multnomah County may not address administration of a Clark County estate.
Unmarried partners do not receive these default rules. Washington's community property statutes apply to spouses and to state registered domestic partners. A long relationship without that status is a different plan, built with titling, beneficiary designations, and contracts, not with an assumption of equal ownership.
Classification is fact-specific. Wages, refinances, home-based businesses, and accounts retitled after a move all affect the result. An inventory of title, earnings, and any Oregon holdings belongs in the file before anyone signs new deeds or agreements. That inventory is the core of estate planning services in Vancouver for couples with property on both sides of the river.
