Oregon Prenup Laws: Guide for Engaged Couples

Getting married in Oregon? 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.
  • Unenforceable if involuntary, unconscionable when executed, or lacking disclosure without waiver. No “second look” at divorce.
  • Oregon follows the UPAA. Must be in writing and signed before marriage. No notarization requirement, but recommended. Full disclosure or waiver is necessary.
