Washington prenup case
Friedlander v. Friedlander
80 Wn.2d 293, 494 P.2d 208 (1972) · Washington Supreme Court
Last updated 7 min read
Washington Supreme Court established the substantive-or-procedural-fairness framework: a prenup must be either substantively fair OR procedurally fair (full disclosure + independent counsel + voluntary execution).
Why this case matters
Friedlander remains foundational Washington law. The disjunctive framework gives drafters strategic flexibility: invest in procedural robustness OR substantive balance. For high-asset Washington couples, knowing this choice exists is the first step in designing an enforceable agreement.
The facts
The Friedlanders signed a prenup before their Washington marriage. The wife challenged the agreement at divorce, arguing that, as a community-property state, Washington's public-policy interest in fair marital property division should defeat the prenup. The Washington Supreme Court used the case to define the state's framework.
The holding
A prenup is enforceable in Washington if it is either (a) substantively fair — the terms are not disproportionately unfavorable to one party — OR (b) procedurally fair — both parties had full disclosure, both had the opportunity to consult independent counsel, and both signed voluntarily. The disjunctive framework means a procedurally robust agreement can be enforced even with unfavorable terms, and a substantively fair agreement can be enforced even with procedural gaps.
What it means for you
- Washington uses a disjunctive (either/or) fairness test — unusual among US states.
- A prenup with great procedure (independent counsel both sides, full disclosure, plenty of time) can be enforced even if its terms strongly favor one spouse.
- A prenup with one-sided procedure but balanced terms can also be enforced.
- The combination of one-sided procedure AND one-sided terms is what gets struck down.
- Washington is a community-property state, so the default rule absent a prenup is equal division of marital property.
