Why a Washington prenup is different

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

Step 1 Icon

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.
Step 1 Icon

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 a bad idea 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.

First saved us a ton of money over working with lawyers in our local area and the workflows make the process very clear and easy to navigate. The lawyers were clear in their feedback and very timely in their responses. First made things as uncontentious as possible when discussing difficult topics.

First was a fantastic experience. I was very nervous about the prenuptial process-spending the time to find a lawyer, high fees, schedule meetings, and go through the process felt extremely daunting. First made this process smooth and took the stress out of it.

My experience with First was great. The questions were thorough and led to good conversation with my fiancé. Once we talked things through, it was helpful to get additional information from each of the lawyers that we chose to work with in developing our agreement.

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.

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.
