How Washington Divides Property

Washington is a community property state. All assets and debts acquired during marriage are owned equally by both spouses, and this rule applies equally to registered domestic partnerships. One important caveat: if separate property is commingled with community funds — even inadvertently — it can lose its separate character. A prenup documents your pre-marital assets and establishes clear rules to prevent commingling from erasing separate property protections.

How Clause Helps

Your Clause prenup explicitly defines which property is separate and which is marital, overriding Washington's default 50/50 community property split with terms you both agree on.

Washington Prenup FAQ
