Joint Tenancy vs. Tenancy in Common in Washington
How you co-own decides what happens when an owner dies or wants out. The two main forms of co-ownership in Washington, compared in plain English.
When two or more people buy a property together, the deed records not just who owns it but how — and that “how” silently decides what happens at the two moments co-ownership gets tested: when an owner dies, and when an owner wants out. The two workhorse forms:
Joint tenancy with right of survivorship (JTWROS): owners hold equal shares, and when one dies, their share passes automatically to the surviving owner(s) — outside the will, outside probate. Tenancy in common (TIC): owners hold shares (equal or not — 70/30 is fine), each owner’s share is theirs to sell, borrow against, or leave to whomever their estate plan says, and death sends the share through the estate, not to the co-owners.
What each form is actually for
Survivorship is the point of joint tenancy: couples and partners who want the home to flow to each other instantly, without probate. Independence is the point of tenancy in common: unequal contributions, co-buying friends or siblings, investment partners — anyone who wants their share to remain their asset, inheritable by their heirs. That’s why TIC plus a written co-ownership agreement is the standard recommendation for unmarried co-buyers: the agreement handles exits and disputes the deed can’t.
The Washington wrinkle: community property
Washington is a community-property state, and for married couples (and registered domestic partners), community property is its own ownership regime with its own survivorship option and — frequently decisive — potential tax advantages at death related to how inherited property’s cost basis is treated. Whether community property with right of survivorship beats joint tenancy for a specific couple is exactly the kind of question that looks simple and is not: it touches estate plans, separate-vs-community characterization of the down payment, and federal tax treatment. This is the paragraph where we say it plainly: how to vest title is an estate-planning decision; spend the hour with an attorney or CPA rather than defaulting to whatever the escrow officer’s form suggests. (More options and trade-offs in how to vest title in Washington.)
The failure modes, by form
Joint tenancy: an owner who wants out can’t just leave their half to someone in a will — survivorship overrides wills, a fact that surprises families regularly. And severing a joint tenancy (converting to TIC) can sometimes be done unilaterally, which surprises the other owner.
Tenancy in common: nothing forces co-owners to agree. An owner can sell their share to a stranger; an heir can inherit into your kitchen; deadlocks ultimately resolve through a partition action — a court-ordered sale that’s expensive, slow, and ruinous to relationships. The written co-ownership agreement (buyout rights, sale triggers, expense splits) exists to keep you out of that courtroom.
Practical notes for closing week
Escrow will ask how you want to vest, usually via a short form with checkboxes that carry lifetime consequences. Decide before signing week, not at the table. Vesting can be changed later by deed — but changes can have tax and lender implications, so “fix it later” isn’t free. And remember the deed controls over the will only for survivorship forms; aligning your vesting with your estate documents is the whole game.
A good agent spots when your situation doesn’t fit the default checkbox and says “talk to an attorney before Thursday” — early enough to matter. Compare what Greater Seattle agents charge for that kind of attention when Manaky Homes opens its free fee marketplace. Join the waitlist.
