Oregon Prenuptial Agreement Overview
Oregon has adopted the Uniform Premarital Agreement Act (UPAA), which provides a standardized framework for prenuptial agreements in the state. Under Oregon law, a prenuptial agreement must be in writing and signed by both parties to be enforceable. The agreement becomes effective upon marriage and can address property rights, spousal support, estate planning, and other financial matters not in violation of public policy.
Oregon is an equitable distribution state, meaning that without a prenup, marital property is divided by the court in a manner it considers fair and equitable — but not necessarily equal. Oregon courts consider various factors including the length of the marriage, each spouse's contributions and earning capacity, and the economic circumstances of each party. A prenup removes this uncertainty by allowing couples to define their own terms for property division.
Prenuptial agreements are an increasingly common financial planning tool for Oregon couples at all income levels. Whether you are protecting a family business, safeguarding an inheritance, clarifying responsibility for student loan debt, or simply establishing clear financial expectations, a properly drafted Oregon prenup provides certainty that state default laws cannot. Working with a Oregon family law attorney who is experienced in prenuptial agreements is the best way to ensure your agreement meets all state requirements.

Oregon Prenuptial Agreement Legal Requirements
To create a valid and enforceable prenuptial agreement in Oregon, you must meet the following legal requirements established by state law:
Important: Oregon Execution Requirements
Oregon requires that prenuptial agreements be in writing and signed by both parties. The agreement becomes effective upon marriage. Both parties should provide complete financial disclosure and have adequate time to review the agreement before signing. Working with independent Oregon family law attorneys is strongly recommended for both parties.
Formal Requirements
- Written Agreement: Oregon requires the prenuptial agreement to be in writing — oral prenuptial agreements are not enforceable
- Both Parties Must Sign: The agreement must be signed by both prospective spouses to be valid
- Voluntary Execution: Both parties must sign voluntarily without duress, coercion, or undue influence
- Full Financial Disclosure: Both parties must provide complete and accurate disclosure of all assets, debts, income, and financial obligations
- Not Unconscionable: The agreement must not be so one-sided as to be unconscionable under Oregon law
What Can Be Addressed
- Rights and obligations in property owned by either or both parties
- Disposition of property upon separation, divorce, or death
- Spousal support (alimony) terms, modifications, or waivers
- Life insurance, estate planning, and inheritance provisions
- Any other matter not in violation of Oregon public policy or criminal law
Oregon Prenup Enforceability Rules
Oregon follows the standard UPAA enforcement framework. A prenup is unenforceable if the challenging party proves involuntary execution, or unconscionability combined with inadequate financial disclosure. Oregon courts generally uphold properly executed prenuptial agreements when the basic UPAA requirements are satisfied. The burden of proof falls on the party seeking to invalidate the agreement.
Spousal Support Waiver
Permitted — Oregon courts allow spousal support waivers in prenuptial agreements, subject to unconscionability review
Sunset Clause Recognition
Recognized — Oregon courts will enforce clearly written sunset clauses that were voluntarily agreed upon by both parties
Unconscionability Standard
Evaluated at the time of execution — Oregon courts examine whether the agreement was fundamentally unfair when signed, considering the adequacy of disclosure and the bargaining positions of the parties
