Decades ago, the term “prenup” or prenuptial agreement carried somewhat of a social stigma. Many people viewed prenups as a pessimistic or unlucky move that basically signaled that you assumed your marriage would eventually fail. However, as greater awareness and understanding of how prenuptial agreements work spread, more people stated that they would be open to signing a prenup before entering into marriage. According to recent data, approximately 50 percent of adults in the United States reported that they at least somewhat supported the use of prenups, even though only roughly one in five married couples has a prenuptial agreement in place. Interestingly, younger generations, particularly Millennials and Gen Z couples, are more likely to use prenuptial agreements before they marry. Since more Americans are waiting longer to get married, people are coming into the marriage with substantial individual assets (and debts), which makes the idea of putting a prenup in place worth considering. In the event that the romantic partnership ends in divorce, the prenuptial agreement can be used to govern the division of assets and enforce the couple’s vision for their separation.
When crafted clearly and with the guidance of a highly qualified Seattle divorce and family law attorney, prenuptial agreements can play a critical role in simplifying the divorce process and ensuring that both parties walk away from the marriage on stable financial footing. However, just because the couple has jotted down some notes about what happens in the event of separation does not automatically mean that a valid and legally enforceable prenuptial agreement is in place. Let’s take a look at how to create and enforce a prenuptial agreement in Washington state, as well as the benefits of partnering with a trusted and experienced Seattle divorce lawyer who can support you along the way.
First, it’s important to understand what makes a prenup legally valid and enforceable in Washington state. While there is no official legal document that the parties must use to create a valid prenuptial agreement, there are key provisions that must be included in order for the contract to be binding and enforceable. Here are the three essential factors that prenup agreements should have in King County and Pierce County.
Both parties must sign the prenuptial agreement of their own free will. In other words, they must voluntarily choose to sign this legally binding document and not do so under duress, coercion, or last-minute pressure (i.e., ultimatums).
Each party must provide a complete and honest disclosure of all their individual assets and liabilities (debts) before signing the prenuptial agreement. Concealing assets or misrepresenting your sources of income can invalidate the prenup.
The terms set forth in the prenuptial agreement must be fair and reasonable. Although the proposed division of assets and liabilities does not need to be an even fifty-fifty split, it cannot be unreasonable or leave one spouse with substantially fewer assets than the other in the event of divorce.

When drafting a prenuptial agreement, you have some flexibility in the topics you address and how you and your spouse plan on navigating the divorce process, should the need arise. You can use the prenuptial agreement to address topics like property division, spousal maintenance, and how you plan on handling debt obligations in the event of a divorce. Let’s take a look at some of the common terms that are typically included in a Washington state prenup agreement.
One of the most time-consuming steps during the Washington divorce process is negotiating a fair and equitable division of assets and debts. Clearly labeling the assets you plan on bringing into the marriage as separate assets (such as an inheritance you received or a precious family heirloom) can keep these assets apart from the property you acquire during the course of the marriage (which is typically considered community property, even if one spouse technically earned or paid for it). Should the marriage end, you can point to the terms of the prenuptial agreement to show that a specific asset belongs to one party and is not subject to the state’s community property laws.
Another topic that prenuptial agreements can address is the management of assets during the marriage. For example, you can use the prenup to define how major purchases, sales, or property management decisions should be made to minimize confusion and complications later on.
If you enter into a second marriage without putting a prenuptial agreement in place and you pass away, Washington’s succession laws may prevent your child from a previous marriage from inheriting your property. You can use a prenuptial agreement to protect the inheritance rights of any children you have from previous relationships and ensure that they receive the assets you intend to leave to them.
There are certain topics that a prenuptial agreement cannot address. For example, you cannot establish the terms concerning child support calculations or child custody determinations, as these matters must be decided based on the best interests of the child at the time of the divorce. Additionally, any provisions that encourage divorce or provide financial incentives for ending the marriage are not enforceable. Some couples want to include provisions that address specific weight or appearance obligations (i.e, each spouse must stay under a certain weight limit, work out a specific number of times per week, etc.), but these are rarely enforced by the court.

If a couple has a valid prenuptial agreement in place, they can use this document to guide them through the divorce process in Washington state. Many divorcing couples find that having a prenuptial agreement in place helps to minimize confusion and conflict during these challenging negotiations, as many of the considerations have already been addressed and outlined in this legal document. Should a dispute arise during the divorce process, the court can use the terms set forth in the prenup to inform its decisions. The ways in which the court may use the prenuptial agreement during divorce proceedings depend on the specificity of the language, the scope of the terms included, and the circumstances in which the agreement was drafted.
In some cases, one party may seek to challenge specific aspects of the prenup or ask the court to invalidate it altogether. Here are some of the reasons that one spouse may contest a prenup in King County or Pierce County.
If a spouse believes that they signed the prenup under duress or extreme pressure, they can raise these concerns with the court and seek to have the prenup invalidated.
One spouse may claim that the other party failed to fully disclose their assets, debts, and income at the time the prenup was drafted. Or, they may have intentionally misled or misrepresented their financial situation, which can invalidate the prenup.
Before either party signs a prenuptial agreement, they have the right to consult an attorney to review the document and ensure that the proposed terms are fair. If a spouse was not provided the opportunity to hire independent counsel to review the prenuptial agreement before signing, they may contest the validity of the prenup.

Clear and valid prenuptial agreements can be particularly useful in complex or high-asset divorce cases. Prenuptial agreements typically provide nuanced accounts of each party’s assets, debts, and income sources to guide productive negotiations in the event of divorce. During complex or contested divorces, the court can refer to the prenuptial agreement and enforce the terms in order to resolve the case and finalize the divorce. If you are concerned about the validity of the prenup or you wish to contest one of the terms, reach out to an experienced and dedicated Seattle divorce attorney to explore your options and determine the most strategic course of action.
Yes, if the court finds that the prenup is not legally valid. Signing it under duress, failing to fully and honestly disclose each party’s assets and debts, and other issues can make the prenup unenforceable.
No. Even if the parties address these matters in the prenup, the court will not enforce these terms. The Washington court decides child support and parenting plan matters at the time of separation.
