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

First vs hiring two Washington attorneys on your own
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 both partners, 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 $3,000 to $10,000 or more for complex situations.
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 $3,000 to $10,000 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.
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.
