Getting married in Washington? A prenuptial agreement lets you set clear expectations about property, debt, and (where allowed) support—so you’re not relying only on default state rules.
Key points
- Prenups are recognized if they’re voluntary, in writing, and signed by both partners.
- Courts require both substantive and procedural fairness. Factors include timing, opportunity to seek counsel, and adequacy of disclosure.
- Must be in writing, signed before marriage. Notarization is not mandated but advised. Full and fair disclosure is necessary.
- This is a <strong>community‑property</strong> jurisdiction—your prenup can define what stays separate and how community property is handled.
