Why a Washington prenup is different

A First prenup is built around Washington's rules and customized for you from the ground up.

Community property

Washington is one of nine community property states. That means most of what either partner earns or acquires during the marriage, including wages, business income, and retirement contributions, is presumed to be owned equally, and debts taken on during the marriage are usually treated as joint. Without a prenup, that is the default a Washington court would apply. A prenup is how you and your partner write your own rules instead, designating what stays separate and how income, business interests, and debts are handled.

No mandatory waiting period

Washington also gives couples more scheduling flexibility than many states. There is no mandatory waiting period before signing, unlike California's seven-day rule. While that flexibility is lawful, signing in the final days before the wedding is still riskier because Washington courts look closely at whether both partners had a genuine chance to review the agreement and get their own advice. The earlier you start, the stronger the agreement tends to be. See our full Washington prenup guide

Washington prenup laws at a glance

Signing
In writing and signed by the partner it will be enforced against, which is why you both sign. Notarizing is customary, and First includes it RCW 19.36.010
What a court checks
First, whether the agreement makes a fair and reasonable provision for the partner not seeking to enforce it. If it does not, whether both partners disclosed fully and signed voluntarily, on independent advice from counsel and with full knowledge of their rights In re Marriage of Matson, 107 Wn.2d 479 (1986)
Burden of proof
On the partner seeking to enforce the agreement In re Marriage of Bernard (Wash. 2009)
Without a prenup
What either of you acquires during the marriage is community property. At divorce a court divides both community and separate property in the way it finds equitable, which does not always mean equal RCW 26.16.030; RCW 26.09.080
Separate by default
What each of you owned before the marriage, and gifts and inheritances received during it, with their rents, issues and profits RCW 26.16.010
Waiting period
None, but courts weigh whether both partners had a real chance to review the agreement and consult counsel. Most attorneys recommend finalizing at least 30 days before the wedding
Two attorneys, hired separately
$3,700 to $12,400 for the couple, at Seattle-area rates of $350 to $500 an hour
With First
$649 flat for Self-Serve, or $3,500 for Lawyer Review with both attorneys included. Online notarization included in both

How much does a prenup cost in Washington?

Key considerations

A Washington prenup with two independent attorneys is $3,500 total through First, with one attorney for each partner, consultations, revisions, and online notarization included. Hiring two firms separately in Washington, where family law attorneys bill $250 to $500 an hour and Seattle rates run $350 to $500, more often lands between $3,700 and $12,400 for the couple.

Hired separately, that work is billed hourly across two firms, so the final number is hard to predict before you start. First is one flat price, with no retainers and no hourly bills, and each of you gets your own independent attorney.

The hourly figures also price only the legal work. Hiring on your own means building a shortlist of local firms, calling each one, booking consults, and confirming both fee and availability against your wedding date, then running all of it again because your partner needs a different attorney. First's network is made up of local Washington-licensed family law attorneys who hold availability for First couples, so you each pick yours and start.

Washington prenup questions, answered

Is a prenup enforceable in Washington?

Yes. Washington courts uphold a prenup when it makes a fair and reasonable provision for the partner not seeking to enforce it, or, failing that, when both partners made full financial disclosure and signed voluntarily with the chance to consult their own attorney. The process behind the agreement matters as much as the terms, so disclosure, timing, and access to counsel are what make a Washington prenup hold up.

How much does a Washington prenup cost?

With First, a Washington prenup is a flat fee: $649 for Self-Serve, or $3,500 for Lawyer Review, which includes an independent attorney for each partner. A traditional process with separate attorneys for both partners, which Washington courts favor, commonly runs $3,700 to $12,400 for the couple at Seattle-area rates.

Do I need to find a local Washington prenup lawyer, or can I use First?

You still get a local attorney with First. Lawyer Review at $3,500 includes an independent Washington-licensed family law attorney for each of you, drawn from a vetted local network that holds availability for First couples, so you get the two-attorney structure Washington courts look for without building a shortlist of local firms and calling each one. Hiring two local attorneys separately in Washington typically runs $3,700 to $12,400 for the couple, billed hourly across two firms. Self-Serve at $649 is the option without attorneys.

Do you do prenups in Seattle, Tacoma and Spokane?

Yes. First serves couples across Washington, including Seattle, Bellevue and the King County suburbs, Tacoma in Pierce County, Everett in Snohomish County, and Spokane and Vancouver. Lawyer Review at $3,500 includes an independent Washington-licensed family law attorney for each partner, and Self-Serve is $649. Both are completed online, so where in the state you live does not change the process or the price.

How much does a prenup cost in Seattle?

Seattle-area family law attorneys bill $350 to $500 an hour, and because each partner needs their own, hiring two separately commonly runs $3,700 to $12,400 for the couple. First is flat: $3,500 for Lawyer Review with both attorneys included, or $649 for Self-Serve.

Does Washington require a waiting period before signing a prenup?

No. Washington does not impose a mandatory waiting period before signing a prenup. Timing still matters, because courts look at whether both partners had a real chance to review the agreement and consult counsel, so most attorneys recommend finalizing at least 30 days before the wedding and starting earlier.

Is Washington a community property state, and how does that affect my prenup?

Yes. Washington is one of nine community property states, so income, assets, and debts acquired during marriage are presumed jointly owned by both spouses. A prenup lets you designate specific property as separate and override those defaults, which Washington courts permit when the agreement is fair, voluntary, and supported by full disclosure.

Is Washington State a 50/50 state when it comes to divorce?

Not automatically. Washington presumes that what either of you acquires during the marriage is community property, owned by both. At divorce, though, a court divides both your community and your separate property in the way it finds equitable, weighing factors such as the length of the marriage and each spouse's economic circumstances, and equitable doesn't always mean equal. A prenup lets the two of you agree on the split in advance.

Is a house I bought before marriage protected in Washington?

It starts out as yours. Washington treats property a spouse owned before the marriage, along with its rents, issues and profits, as that spouse's separate property. Separate property can still be divided in a divorce, because a Washington court can divide both community and separate property in the way it finds equitable. A prenup is how you two agree in advance that the house stays with the partner who brought it in.

Can I do a Washington prenup online and have it hold up?

Yes. Completing a prenup online does not affect whether it holds up. Enforceability depends on the structure of the agreement: a written agreement signed voluntarily, full financial disclosure, and a real opportunity for each partner to consult counsel. First is built around all of these.

What is the difference between Self-Serve and Lawyer Review in Washington?

Self-Serve at $649 is a guided, fully online prenup customized to Washington, including spousal maintenance terms, best when your finances are straightforward and you are comfortable deciding together without an attorney in the room. Lawyer Review at $3,500 adds an independent attorney for each partner, which Washington courts give particular weight to, plus the ability to edit the underlying language, and suits business owners, complex assets, or a prior marriage.
