Frequently asked questions

How much does a prenup cost in Oregon?
A prenuptial agreement in Oregon typically costs $2,500 – $5,000 for a simple agreement, $5,000 – $10,000 for a moderate one, and $10,000 – $20,000 for complex estates with businesses or multi-state property. Average attorney rates in the state run $275–$500/hr. Both spouses hiring separate attorneys adds 50–75% to the total — and is strongly recommended.
Does Oregon require a notary for a prenup?
No, Oregon does not require notarization by statute. A prenup must be in writing and signed by both parties; notarization is a best practice for evidentiary reasons but not a legal requirement.
Do both spouses need their own attorney in Oregon?
Independent counsel for each spouse is strongly recommended (and often outcome-determinative if litigated). Joint representation — one attorney for both spouses — is among the most common grounds for a court to invalidate a prenup later. Even where it isn't strictly required, paying one lawyer to "save money" frequently costs the entire agreement.
What statute governs prenups in Oregon?
Oregon prenups are governed by Or. Rev. Stat. §§108.700 to 108.740. The full statute text is available on the state legislature site.
