Why an Oregon prenup is different
A First prenup is built around the laws of Oregon, and you, from the ground up.
Oregon has a prenup statute, and it asks for little on paper
Oregon adopted the Uniform Premarital Agreement Act in 1987. It requires a written agreement signed by both partners, and nothing more: no consideration, no notary, no witnesses. The agreement takes effect the day you marry. What the statute is strict about is not the paperwork but the two things a court checks if the agreement is ever challenged.
The test is voluntariness and disclosure
An Oregon court will not enforce a prenup if the partner challenging it proves they did not sign voluntarily. Nor will it enforce one that was unconscionable when signed, where that partner got no fair and reasonable disclosure of the other's finances, waived none in writing, and had no adequate knowledge of them otherwise. The judge decides unconscionability as a matter of law.
A court’s “just and proper” division is the default you are replacing
Without a prenup, an Oregon court divides property in the way it finds just and proper in all the circumstances, starting from a presumption that both spouses contributed equally to property acquired during the marriage, including through work as a homemaker. Just and proper doesn't always mean equal, and it is decided by a judge who does not know either of you. A prenup is how you two decide instead.

First vs hiring two Oregon attorneys on your own
Key considerations
An Oregon prenup is $649 flat for the couple through First, completed online with notarization included. Hiring two attorneys separately in Oregon, where family law attorneys average $348 an hour and the Portland area runs $300 to $400, commonly lands between $3,200 and $9,900 for the couple.
Hired separately, a prenup is quoted per partner and often billed hourly, so the final number is hard to predict before you start. First is one flat price for both of you, with no retainer and no hourly bills.
The fees also price only the legal work. Hiring on your own means building a shortlist of Oregon family law attorneys, calling each one, booking consults, and confirming both fees and availability against your wedding date, then running all of it again because your partner needs a different attorney. First replaces this work with a process the two of you complete together, at your own pace, from anywhere in the state.

Oregon prenup questions, answered
Is a prenup enforceable in Oregon?
Yes. Oregon's Uniform Premarital Agreement Act requires a prenup to be in writing and signed by both partners, and it takes effect when you marry. A court will refuse to enforce one only if the partner challenging it proves they did not sign voluntarily, or that it was unconscionable when signed and, before signing, they were not given a fair and reasonable disclosure of the other partner's finances, did not waive that disclosure in writing, and had no adequate knowledge of those finances otherwise. An agreement built on full disclosure and signed voluntarily, with time to spare, is built to pass that test.
How much does a prenup cost in Oregon?
With First, an Oregon prenup is $649 flat for the couple, with online notarization included. Hiring attorneys instead commonly runs $3,200 to $9,900 for the couple, billed hourly at Portland-area rates of $300 to $400 an hour, since each partner needs their own attorney and the hourly math runs twice. Our guide to what a prenup costs walks through that math.
Do you do prenups in Portland, Salem and Eugene?
Yes. First serves couples across Oregon, including Portland and the Multnomah, Washington and Clackamas county suburbs such as Beaverton, Hillsboro and Gresham, Salem, Eugene, Bend and Medford. Self-Serve is $649 flat for the couple and is completed online, so where in the state you live does not change the process or the price.
How much does a prenup cost in Portland?
Portland-area family law attorneys commonly bill $300 to $400 an hour. Because each partner needs their own, hiring two separately commonly runs $3,200 to $9,900 for the couple. First is $649 flat for the couple, with online notarization included.
Do both people need a lawyer for a prenup in Oregon?
No. Nothing in Oregon's Uniform Premarital Agreement Act requires either partner to be represented by an attorney for a prenup to be valid. What the statute tests is whether each partner signed voluntarily and whether each had a fair and reasonable disclosure of, or adequate knowledge of, the other's finances. Both are within your control, and they are what First Self-Serve is built around.
Can I do an Oregon prenup online?
Yes. Nothing in Oregon law treats an agreement differently because of how it was produced. What matters is that both partners disclosed their finances, both signed voluntarily, the terms are not unconscionable, and the agreement was drafted to Oregon law. First Self-Serve is $649 for the couple and includes online notarization.
Does an Oregon prenup have to be notarized?
Oregon's statute requires only that the agreement be in writing and signed by both partners; it does not require notarization or witnesses. Notarizing is still worth doing, because a notarized signature is straightforward evidence that both partners signed voluntarily, which is the first thing an Oregon court examines. First includes online notarization at no extra cost.
When should we sign a prenup in Oregon?
As early as you reasonably can. Oregon has no statutory waiting period, but timing is one of the clearest signals a court reads when someone argues they did not sign voluntarily. An agreement produced days before the ceremony, to a partner who has not seen it, is the fact pattern most likely to be challenged. Signing months ahead, after both partners have read it and had a real chance to ask questions, removes that argument.
Is First Self-Serve right for a complex Oregon prenup?
Yes. Self-Serve covers business ownership, stock, options and RSUs, real estate, inheritance and gifts, existing child support or spousal support obligations, and spousal support terms, all for $649 flat for the couple. If you'd like to talk your situation through first, book a free 20-minute call.
What does an Oregon prenup cover?
An Oregon prenup can set out what happens to property if the marriage ends, and it can modify or eliminate spousal support. Two limits apply. It cannot adversely affect a child's right to support. And if eliminating spousal support would leave a spouse eligible for public assistance, an Oregon court can order support to the extent needed to prevent that, whatever the agreement says.
