What You Need to Know About Prenups in Oregon

Prenuptial agreements in Oregon are governed by the Uniform Premarital Agreement Act (UPAA), which Oregon adopted in 1987 and codified at ORS 108.700 to 108.740. Oregon is one of the majority of states that follow the UPAA framework, which sets out clear requirements for when a premarital agreement is valid and enforceable.

Oregon adopted the original Uniform Premarital Agreement Act framework, with later legislative refinements. The statute makes a properly executed agreement enforceable without separate consideration, and the agreement takes effect automatically once the couple marries.

Oregon is an equitable distribution state, not a community property state. That means that without a prenuptial agreement, a court divides marital property in a way it considers “just and proper,” which is not the same as a 50/50 split and is far less predictable than couples expect. A prenuptial agreement lets you decide these terms yourselves rather than leaving them to a judge.

To be valid and enforceable in Oregon, a prenuptial agreement must:

  • Be in writing. Oral premarital agreements are not enforceable in Oregon.
  • Be signed by both parties. Oregon does not require witnesses, and the statute does not require notarization, though signing formalities are still recommended as best practice.
  • Be entered into voluntarily by both parties, without coercion or duress.
  • Be accompanied by fair and reasonable financial disclosure, unless that disclosure is expressly waived in writing.

What a prenup can cover in Oregon

  • Division of property and assets in the event of divorce or death
  • Rights and obligations regarding separately owned and jointly owned property
  • Whether and how spousal support is modified or eliminated
  • Protection of a business, professional practice, or future business interests
  • Treatment of debts, gifts, and inheritances
  • Estate and death-benefit provisions consistent with Oregon law

What a prenup cannot do in Oregon

  • Reduce or eliminate a child’s right to support. Child support cannot be adversely affected by a premarital agreement.
  • Eliminate spousal support if doing so would leave one spouse eligible for public assistance. In that situation, an Oregon court can require support despite the agreement.
  • Include terms that violate public policy or criminal statute.
  • Be enforced if it was signed involuntarily, or if it was unconscionable when signed and that party did not receive fair disclosure or knowingly waive it in writing.

The two factors that decide whether an Oregon prenup holds up are voluntary signing and fair financial disclosure. Under ORS 108.725, an agreement can be set aside if one party proves they did not sign voluntarily, or that the agreement was unconscionable when signed and they were not given a fair picture of the other party’s finances and did not waive that disclosure in writing. Full, documented financial disclosure is the single best protection for an enforceable Oregon agreement.

I spent years helping couples navigate divorce. The financial damage I saw was not inevitable. Assets split under laws couples never understood, decades of work undone. Most of it could have been addressed clearly and fairly before the wedding with a well-crafted prenuptial agreement. I built Prenups.com to make that process accessible for any couple that wants to start their marriage on the same page, financially and legally.

What is a prenuptial agreement in Oregon?

A prenuptial agreement in Oregon is a written contract signed by two people before marriage that sets out how their property, debts, and spousal support will be handled if the marriage ends in divorce or death. In Oregon, these agreements are governed by the Uniform Premarital Agreement Act, codified at ORS 108.700 to 108.740, and become effective once the couple marries.

Yes. Oregon enforces prenuptial agreements that meet the requirements of the Uniform Premarital Agreement Act. The agreement must be in writing, signed by both parties, and entered into voluntarily. An agreement can be challenged if one party proves they did not sign voluntarily, or that it was unconscionable when signed and they were not given fair financial disclosure.

An Oregon prenup must be in writing, signed by both parties, and entered into voluntarily without coercion. Oregon does not require witnesses or notarization by statute, although signing formalities are recommended. Fair and reasonable financial disclosure, or a written waiver of disclosure, is critical to enforceability under ORS 108.725.

At Prenups.com, an Oregon prenuptial agreement is a flat fee of $3,500. There is no hourly billing and no surprise charges. The fee includes drafting, all revisions and negotiation, and coordinated online signing. Postnuptial agreements are $4,500. Complex or high net worth matters are handled through our Platinum service starting at $10,000.

Most Oregon prenuptial agreements are completed in about two to three weeks from the initial consultation, depending on how quickly both parties review and respond. We recommend starting well before the wedding so there is no time pressure, since voluntary signing is a key enforceability factor in Oregon.

Yes. A prenuptial agreement must be signed before the marriage and takes effect on the date of marriage. If you are already married, the equivalent document is a postnuptial agreement. Oregon does not impose a fixed statutory waiting period between signing and the wedding, but signing well in advance helps demonstrate the agreement was entered into voluntarily.

Yes. Under ORS 108.725, an Oregon prenuptial agreement can be set aside if the party challenging it proves they did not sign voluntarily, or that the agreement was unconscionable when it was executed and, before signing, they were not given fair and reasonable disclosure of the other party’s finances and did not voluntarily waive that disclosure in writing. Whether an agreement is unconscionable is decided by the court as a matter of law.

An Oregon prenup can address division of property and assets, separate and jointly owned property, treatment of debts, gifts, and inheritances, protection of a business or professional practice, modification or elimination of spousal support, and estate and death-benefit provisions, as long as the terms do not violate public policy or law.

An Oregon prenup cannot reduce or eliminate a child’s right to support, and it cannot include terms that violate public policy or criminal law. It also cannot fully eliminate spousal support if doing so would leave one spouse eligible for public assistance at separation or divorce, in which case a court can order support despite the agreement.

Oregon does not legally require each party to have a separate attorney. However, independent representation strengthens the argument that the agreement was entered into voluntarily and with full understanding, which directly supports enforceability. At a minimum, the party who did not have counsel should have a clear, documented opportunity to obtain it.

Yes. A prenuptial agreement is one of the most effective ways to protect a business in Oregon. It can confirm that a business is separate property, address future growth in value, and prevent a spouse from acquiring an interest in the company during divorce. This is especially important for founders, partners, and professional practice owners.

Yes. If you are already married, a postnuptial agreement can address the same financial and property questions as a prenuptial agreement. Oregon recognizes agreements between spouses that are in writing, signed voluntarily, and supported by fair disclosure. At Prenups.com, an Oregon postnuptial agreement is a flat fee of $4,500.
