Oregon law under ORS 108.700-108.740 governs prenuptial agreements through the Uniform Premarital Agreement Act (UPAA), requiring only a written document signed by both parties to create a legally binding contract. The conversation about asking for a prenup does not need to be adversarial. Approximately 15% of married couples in the United States have a prenuptial agreement, according to a 2022 Harris Poll survey, and that number rises to 40% among couples married after 2020. In Oregon, where courts divide property equitably under ORS 107.105(1)(f) rather than equally, a prenuptial agreement gives both partners control over how assets, debts, and spousal support are handled if the marriage ends. This guide walks you through how to bring up a prenup with your partner in Oregon, what the law requires, and how to have the conversation without damaging your relationship.

Why Couples in Oregon Should Consider a Prenuptial Agreement
Oregon is an equitable distribution state, meaning courts divide marital property in a manner deemed just and proper under ORS 107.105(1)(f), which does not guarantee a 50/50 split. A prenuptial agreement allows Oregon couples to define their own property division terms, potentially saving tens of thousands of dollars in contested divorce litigation that averages $15,000-$30,000 per spouse. Without a prenup, all property, including separate assets brought into the marriage, can theoretically be subject to court division under Oregon law.
Oregon abolished fault-based divorce entirely under ORS 107.036, so the sole ground for dissolution is irreconcilable differences under ORS 107.025. This means neither spouse needs to prove wrongdoing, which makes the financial terms of divorce even more dependent on negotiation or judicial discretion. A prenuptial agreement removes that uncertainty by establishing clear rules before any conflict arises. Oregon courts generally uphold prenuptial agreements when they meet the requirements of ORS 108.705 and ORS 108.725, making them a reliable planning tool.
Suggesting a prenuptial agreement is not a prediction of divorce. It is a financial planning exercise similar to purchasing homeowner's insurance. Couples who discuss finances openly before marriage report 30% higher relationship satisfaction in the first 5 years, according to research published by the National Endowment for Financial Education. The prenup conversation can strengthen your relationship by forcing honest discussions about debt, assets, business interests, and long-term financial goals.
When to Bring Up the Prenup Conversation in Oregon
The ideal time to bring up a prenup in Oregon is 4-6 months before the wedding date, giving both partners adequate time to consult independent attorneys, gather financial documents, and negotiate terms without time pressure. Oregon law under ORS 108.725(1)(a) requires that a prenuptial agreement be executed voluntarily, and courts have scrutinized agreements signed under time pressure as potentially involuntary. In Rudder v. Rudder, 230 Or App 437, the Oregon Court of Appeals examined voluntariness as a core enforceability factor.
Avoid raising the prenup topic during a stressful period such as immediately after an engagement party or while deep in wedding planning logistics. Choose a private, calm setting where neither partner feels ambushed. A Saturday morning at home, during a planned financial discussion, or after a relaxed dinner are all appropriate moments. The goal is to create space for an honest conversation rather than a confrontation.
Timing also matters for legal strategy. Oregon attorney fees for drafting a prenuptial agreement typically range from $1,500-$5,000 per spouse depending on complexity, and both parties should have independent legal counsel. Starting the conversation 4-6 months out allows time to interview attorneys, complete financial disclosure, draft the agreement, review revisions, and sign the final document well before the wedding. Agreements signed the week before a wedding face heightened scrutiny in Oregon courts.
How to Start the Prenup Conversation Without Offending Your Partner
The most effective way to bring up a prenup without offending your partner is to frame it as a mutual financial planning tool rather than a protection against the other person. Lead with statements about protecting both partners equally, not just your own assets. For example, say, "I want us to make financial decisions together now so neither of us is ever at a disadvantage," rather than, "I need to protect my assets."
Here are 5 conversation starters that Oregon couples have used successfully:
- "I read that Oregon divides property based on what the court thinks is fair, not automatically 50/50. I would rather we decide together what is fair for us."
- "My financial advisor suggested we talk about a prenup as part of our overall financial plan, the same way we are talking about retirement accounts and insurance."
- "I want to make sure that if anything ever happened, we would both be protected. A prenup can include provisions that benefit both of us."
- "I know someone who went through a divorce without a prenup, and the court process took 18 months and cost them over $40,000. I want us to avoid that kind of uncertainty."
- "Oregon law lets us decide in advance how we handle property, debts, and even spousal support. I think we should take advantage of that control."
The prenup conversation works best when both partners understand that Oregon's Uniform Premarital Agreement Act under ORS 108.710 allows agreements to cover property rights, spousal support, life insurance beneficiaries, choice of law, and any other matter not in violation of public policy or criminal statutes. Framing the discussion around these broad possibilities shows that a prenup is not just about money. It is about making intentional decisions as a team.
What Oregon Law Requires for a Valid Prenuptial Agreement
Oregon requires a prenuptial agreement to be in writing and signed by both parties under ORS 108.705, with no requirement for witnesses, notarization, or any exchange of consideration. The agreement becomes effective upon marriage under ORS 108.715. After marriage, the agreement can be amended or revoked only by a written agreement signed by both parties, and no consideration is needed for the modification under ORS 108.720.
Oregon courts will refuse to enforce a prenuptial agreement under ORS 108.725(1) if the challenging party proves one of two things: (1) the agreement was not executed voluntarily, or (2) the agreement was unconscionable when executed and the challenging party did not receive fair financial disclosure, did not waive disclosure in writing, and did not otherwise have adequate knowledge of the other party's finances. Unconscionability is determined by the court as a matter of law under ORS 108.725(3).
| Validity Requirement | Oregon Rule | Statute |
|---|---|---|
| Written document | Required | ORS 108.705 |
| Signed by both parties | Required | ORS 108.705 |
| Witnesses | Not required | ORS 108.705 |
| Notarization | Not required (recommended) | ORS 108.705 |
| Consideration | Not required | ORS 108.705 |
| Financial disclosure | Required for enforcement | ORS 108.725(1)(b) |
| Voluntary execution | Required | ORS 108.725(1)(a) |
| Independent counsel | Not required (strongly recommended) | Case law |
| Effective date | Upon marriage | ORS 108.715 |
Oregon's UPAA framework, adopted in 1987, provides fewer procedural safeguards than the newer Uniform Premarital and Marital Agreements Act (UPMAA) that some states have adopted. Oregon has not adopted the UPMAA as of March 2026. This means Oregon does not require a mandatory waiting period between presenting the agreement and signing it, and independent legal counsel is recommended but not legally required. However, the absence of independent counsel for one party can be a factor courts consider when evaluating voluntariness.
What a Prenuptial Agreement Can and Cannot Cover in Oregon
Under ORS 108.710(1), Oregon prenuptial agreements may address 7 specific categories: (a) rights and obligations in property of either or both parties, (b) the right to buy, sell, use, transfer, or manage property, (c) disposition of property upon separation, death, or any other event, (d) modification or elimination of spousal support, (e) making of a will or trust to carry out agreement terms, (f) life insurance beneficiary designations, and (g) any other matter not in violation of public policy or criminal law.
Oregon prenuptial agreements cannot include provisions that adversely affect a child's right to support under ORS 108.710(2). Courts retain full authority to determine child support and child custody regardless of any prenuptial terms. Attempting to limit child support in a prenup will not be enforced and may undermine the credibility of the entire agreement.
The spousal support waiver provision under ORS 108.710(1)(d) comes with one important limitation. Under ORS 108.725(2), if eliminating spousal support would cause one spouse to become eligible for public assistance or medical assistance at the time of separation or divorce, the court may order the other spouse to provide support sufficient to avoid that eligibility. This public assistance exception ensures that prenuptial agreements do not shift the cost of supporting a spouse from the wealthier partner to Oregon taxpayers.
Financial Disclosure: The Foundation of an Enforceable Oregon Prenup
Full financial disclosure is the single most important factor in ensuring an Oregon prenuptial agreement survives a court challenge. Under ORS 108.725(1)(b), a prenup is unenforceable if it was unconscionable at execution and the challenging party was not provided fair and reasonable disclosure of the other party's property and financial obligations. Oregon courts have consistently held that vague or incomplete financial disclosure undermines enforceability.
Both partners should prepare a comprehensive financial disclosure document that includes: all bank and investment accounts with current balances, real estate holdings with appraised values, retirement accounts (401(k), IRA, pension) with current balances, business interests with valuations, outstanding debts including student loans, mortgages, and credit card balances, expected inheritances if known, and current income from all sources. In Oregon, the average household carries approximately $8,500 in credit card debt and $38,000 in student loan debt according to Federal Reserve data, making debt disclosure particularly important.
A written waiver of further disclosure is permitted under ORS 108.725(1)(b)(B), but this waiver must be voluntary and express. Simply providing a summary sheet is generally insufficient. The best practice in Oregon is to attach complete financial statements as exhibits to the prenuptial agreement itself, creating an indisputable record that both parties had access to the other's financial information before signing.
How to Handle Common Objections to a Prenup
When you bring up a prenup, your partner may respond with emotional objections that require empathetic but informed responses. Understanding these objections and addressing them with facts about Oregon law can transform resistance into cooperation.
Objection: "You must think we are going to get divorced." Response: Oregon's divorce rate is approximately 3.4 per 1,000 population according to CDC National Vital Statistics data. Nationally, roughly 40-50% of first marriages end in divorce. A prenup is not a prediction. It is preparation. The same logic applies to health insurance, life insurance, and estate planning, all of which Oregon couples routinely do without assuming the worst.
Objection: "Prenups only protect the wealthy spouse." Response: Oregon prenuptial agreements under ORS 108.710 can protect both partners. A prenup can ensure that a spouse who sacrifices career advancement for the family receives guaranteed spousal support. It can protect a partner's small business from division. It can shield both spouses from each other's premarital debts. In Oregon, where equitable distribution under ORS 107.105(1)(f) gives judges broad discretion, a prenup actually gives the less wealthy spouse more certainty about what they will receive.
Objection: "It feels unromantic." Response: The prenup conversation requires honesty about finances, goals, fears, and expectations. These are the same conversations that marriage counselors recommend. Research from the Gottman Institute shows that financial disagreements are the number one predictor of divorce across all income levels. Addressing finances proactively through a prenup conversation is one of the most constructive things engaged couples can do.
Objection: "My family will think something is wrong." Response: Prenuptial agreements have become mainstream. The American Academy of Matrimonial Lawyers reported in 2022 that 62% of divorce attorneys surveyed saw an increase in prenuptial agreements over the preceding 3 years, with millennials driving the trend. In Oregon, attorneys report that prenup requests have increased significantly among couples where both partners have careers, student debt, or prior marriages.
Cost of Getting a Prenuptial Agreement in Oregon
The total cost of a prenuptial agreement in Oregon ranges from $2,500-$10,000 for both parties combined, depending on the complexity of assets and the attorneys involved. Each spouse should retain independent legal counsel, with individual attorney fees typically running $1,500-$5,000 per person. Oregon attorneys generally bill prenuptial agreement work at hourly rates of $250-$450 per hour in the Portland metropolitan area and $200-$350 per hour in other regions of the state.
For context, this investment is modest compared to the cost of litigating property division in an Oregon divorce without a prenup. Contested divorces in Oregon typically cost $15,000-$30,000 per spouse in attorney fees and can take 12-18 months to resolve. An uncontested divorce using a prenuptial agreement as the framework for property division can be finalized in as little as 4-8 weeks and may cost as little as $2,000-$5,000 total in legal fees plus the $301 filing fee per party under ORS 21.155.
| Cost Category | Without Prenup | With Prenup |
|---|---|---|
| Prenup drafting | $0 | $2,500-$10,000 (one-time) |
| Divorce filing fee | $301 per party | $301 per party |
| Contested divorce attorneys | $15,000-$30,000 per spouse | Unlikely if prenup governs |
| Uncontested divorce attorneys | $2,000-$5,000 total | $2,000-$5,000 total |
| Typical timeline | 12-18 months (contested) | 4-8 weeks (uncontested) |
| Property division outcome | Court discretion | Predetermined by agreement |

Steps to Finalize a Prenuptial Agreement in Oregon
Once both partners agree to move forward with a prenup, the process in Oregon typically follows 7 steps over a 2-4 month period:
- Both partners independently select their own attorneys. Using the same attorney creates a conflict of interest that can jeopardize enforceability. Oregon has approximately 14,000 active bar members, and the Oregon State Bar Lawyer Referral Service can help locate family law attorneys in any county.
- Both partners prepare complete financial disclosure documents listing all assets, debts, income sources, and business interests with supporting documentation.
- One attorney drafts the initial agreement based on the couple's shared goals and that attorney's client's priorities.
- The other attorney reviews the draft and proposes revisions on behalf of their client.
- Both parties negotiate terms through their attorneys until reaching agreement on all provisions.
- Both parties review the final document with their respective attorneys, confirm all financial disclosures are accurate and attached, and sign the agreement. While Oregon does not require notarization under ORS 108.705, having signatures notarized creates a stronger evidentiary record.
- Each party retains an original signed copy, and the agreement becomes effective upon the marriage under ORS 108.715.
Oregon prenuptial agreements can be modified or revoked at any time after marriage by a written agreement signed by both parties under ORS 108.720. Many Oregon couples include a "sunset clause" that automatically terminates the prenup after a specified number of years, commonly 10-15 years, reflecting the reduced relevance of a prenup in long-term marriages.
Frequently Asked Questions
Is a prenuptial agreement legally enforceable in Oregon?
Yes. Oregon enforces prenuptial agreements under the Uniform Premarital Agreement Act, ORS 108.700-108.740. The agreement must be in writing, signed by both parties, executed voluntarily, and supported by fair financial disclosure to withstand a court challenge under ORS 108.725.
How far in advance should I bring up a prenup before an Oregon wedding?
Oregon couples should discuss a prenup 4-6 months before the wedding to allow time for attorney consultations, financial disclosure preparation, negotiation, and signing. Agreements signed under time pressure risk being found involuntary under ORS 108.725(1)(a). Starting early removes the urgency that courts view unfavorably.
Can a prenup waive alimony or spousal support in Oregon?
Yes. ORS 108.710(1)(d) expressly permits modification or elimination of spousal support. However, under ORS 108.725(2), a court may override the waiver if enforcement would make one spouse eligible for public assistance at the time of divorce. This narrow exception protects against extreme outcomes.
Does Oregon require both parties to have separate lawyers for a prenup?
No. Oregon law does not mandate independent legal counsel for prenuptial agreements. However, having separate attorneys significantly strengthens enforceability. Courts evaluating voluntariness under ORS 108.725(1)(a) consider whether both parties had the opportunity to consult independent counsel before signing.
What happens to a prenup if we move out of Oregon?
Under ORS 108.710(1)(g), prenuptial agreements may include a choice-of-law provision specifying which state's laws govern the agreement regardless of where the couple later resides. Without such a provision, the enforceability of an Oregon prenup in another state depends on that state's own UPAA or UPMAA framework and conflict-of-law rules.
Can we change our prenup after getting married in Oregon?
Yes. ORS 108.720 permits modification or revocation of a prenuptial agreement after marriage by a written agreement signed by both parties. No additional consideration is required for the modification. Couples often update their prenup after major life events such as the birth of children, a significant change in income, or the acquisition of substantial new assets.
What makes a prenup unenforceable in Oregon?
An Oregon prenup is unenforceable if it was not signed voluntarily or if it was unconscionable at execution combined with inadequate financial disclosure under ORS 108.725(1). Signs of involuntariness include coercion, presenting the agreement hours before the wedding, or threatening to cancel the marriage. Unconscionability combined with hidden assets is the most common basis for invalidation.
How much does a prenup cost in Oregon in 2026?
A prenuptial agreement in Oregon costs $2,500-$10,000 total for both parties in 2026, with individual attorney fees ranging from $1,500-$5,000 per spouse. Portland-area attorneys typically charge $250-$450 per hour for prenup work. This cost is substantially less than the $15,000-$30,000 per spouse that contested Oregon divorces typically cost.
Can a prenup protect my business in an Oregon divorce?
Yes. ORS 108.710(1)(a) allows prenuptial agreements to address rights and obligations in property of either or both parties, which includes business interests. Without a prenup, Oregon courts under equitable distribution can award a non-owner spouse a share of business value accumulated during the marriage. A prenup can designate the business as separate property and specify alternative compensation.
Does a prenup cover child custody or child support in Oregon?
No. ORS 108.710(2) prohibits prenuptial agreements from adversely affecting a child's right to support. Oregon courts retain full authority over child custody and child support determinations based on the best interests of the child at the time of divorce, regardless of any prenuptial terms. Any custody or support provisions in a prenup will not be enforced.
