The Legal Hill, PLLC is here to help you understand prenuptial agreement law in Washington state, why some choose to use them, and the advantages a prenup has for business owners and general asset protection.
Prenuptial agreements can be a useful tool for couples getting married, but how they function and what can be included is often confusing for those without a family law background.
Prenuptial agreements have grown in popularity over the years. A 2026 Harris poll found that 53% of engaged or married Americans under 45 said they had created a prenup or similar financial structure. This represents a significant increase from a 2022 study that reported 41% of Gen Z and 34% of Millennials said the same.
A prenuptial agreement, or prenup, is a legal contract made between two people before they get married, used to clarify how assets are divided if they get divorced. Washington prenup laws require several elements to be present in each arrangement. These include:
Prenuptial agreements do not require court oversight during the creation process and are typically reviewed by a judge during divorce if one spouse challenges the contract’s legitimacy. Cases are handled through the Superior Court system for the county where you and your spouse reside. For example, Spokane prenup disputes are handled at the Spokane County Superior Court, located at 1116 W Broadway Avenue.
The two main elements the courts examine are substantive fairness and procedural fairness. Substantive fairness refers to the financial standing of each party if the prenup is followed. Terms may depart from equal distribution, but neither spouse can be left destitute. Procedural fairness centers around the creation process. A judge may void a prenup if one party did not have separate legal counsel or if it was created too close to the wedding.
The most important advantage of a prenuptial agreement is classifying assets as marital or separate. Washington is a community property state, meaning that belongings are evenly split between spouses during divorce proceedings. Separate property is excluded from deliberation and includes assets owned before marriage, gifts, or inheritance.
The distinction between separate and marital property can grow blurred during a marriage through commingling. Simple acts like adding a spouse’s name to real estate, using shared assets for a business, or depositing inherited funds into a joint bank account can strip separate property status.
Prenuptial agreements can establish clear delineations between assets before the wedding. This protects valuable assets such as homes, retirement accounts, investments, personal collections, and business interests from being divided or sold later.
Prenuptial agreements can be confusing and require precise wording. Hire a Washington prenuptial agreement lawyer to guide you through the creation process. Services that The Legal Hill, PLLC, can provide include:

How much your Washington State prenuptial agreement attorney costs depends on many factors, such as the complexity of the agreement, the value of the involved assets, the extent of involvement, and the total work hours for the firm. A lawyer hired to finalize documents typically costs less than organizing property and creating a prenup from scratch. During your initial consultation, your attorney can provide a rough estimate for your total bill.
There are several common mistakes people make during prenuptial agreement cases. Examples include failing to disclose all assets during negotiations, attempting to hide or undervalue property, which can invalidate any arrangement and void the contract, or using one attorney for both parties. Having separate legal counsel protects both spouses from unfair clauses and increases the contract’s legitimacy.
Many elements cannot be included in a valid Washington State prenuptial agreement. One major aspect that cannot be included in a prenup is child custody. Custody is determined by what is in the best interest of the child at the time of divorce. Child support is excluded on similar grounds. Another detail not allowed in a prenuptial agreement is guidelines on personal conduct during the union. Details such as household responsibilities or lifestyle choices are unenforceable.
How Washington state prenuptial agreements can protect businesses from divorce complications is by classifying a company as separate property before the wedding. This excludes any business from consideration in property division, avoiding potential liquidation or ownership changes. Without a prenup, companies are often considered community property and counted towards equal distribution.
