WA Prenuptial Agreements

A prenuptial agreement lets two people decide, before the wedding, how Washington’s community property rules will apply to them. Holmes Law prepares and reviews these contracts as a Washington prenuptial agreement attorney for couples in Seattle, Spokane, Tacoma, Vancouver, Bellingham and across the state. The work covers the full life of the agreement: financial disclosure, negotiation, drafting, execution, and coordination with each partner’s estate plan so the agreement still works at death, not only at divorce.

In Washington, Holmes Law’s family law practice is limited to marital agreements, meaning prenuptial and postnuptial agreements. Holmes Law does not handle Washington divorces, custody cases, support modifications or other contested family law matters; those require separate family law counsel. (Idaho is different: Holmes Law offers full-service family law there.) Michael Holmes is admitted in Washington and works with clients remotely. This page goes deeper on the prenuptial agreement itself; for the broader overview of both instruments, see Washington marital agreements. This page is general information, not legal advice for your situation.

Washington Has Not Adopted the Uniform Premarital Agreement Act

Many prenuptial articles online describe the Uniform Premarital Agreement Act as though it applies everywhere. It does not apply in Washington. Title 26 RCW, the domestic relations title, contains the uniform acts Washington has adopted, such as the Uniform Parentage Act (chapter 26.26A RCW), the UCCJEA (chapter 26.27 RCW) and the Uniform Interstate Family Support Act (chapter 26.21A RCW). It contains no premarital agreements chapter. Idaho, California, Texas and North Carolina have enacted a version of the UPAA; Washington and Massachusetts have not.

That means the enforceability of a Washington prenuptial agreement is governed by case law developed by the Washington Supreme Court and Court of Appeals. The practical consequence is significant. Under the uniform act, the party challenging the agreement usually bears the burden. Under Washington case law, the burden runs the other way.

The Two-Prong Test: Friedlander, Matson and Bernard

The Washington test comes from Friedlander v. Friedlander, 80 Wn.2d 293 (1972), and In re Marriage of Matson, 107 Wn.2d 479 (1986). The Washington Supreme Court applied and reaffirmed it in In re Marriage of Bernard, 165 Wn.2d 895 (2009).

Prong one: substantive fairness

The court first asks whether the agreement makes fair and reasonable provision for the spouse who did not seek it. If the agreement is substantively fair, the inquiry can end there. Agreements that preserve each person’s pre-marriage property and allow the community to grow normally are more likely to pass this step than agreements that keep all earnings separate and leave one spouse with little.

Prong two: procedural fairness

If the agreement is not substantively fair, it can still be enforced if it was procedurally fair. The court asks two questions:

  • Did each party make full disclosure of the amount, character and value of the property involved?
  • Was the agreement entered into fully and voluntarily, on independent advice, and with full knowledge by the spouse of his or her rights?

The burden of proving fairness is on the spouse seeking to enforce the agreement. And fairness is measured at the time of execution. In Bernard the Supreme Court declined to move that measurement to the time of enforcement.

What Bernard teaches about timing

In Bernard, the agreement was first presented about 18 days before the wedding, the operative draft arrived only days before the ceremony, and the wife’s counsel could only “hit the high points” with her. The court held that the challenged provisions, which were not substantively fair, failed the procedural prong and could not be enforced. The lesson for Washington couples is direct: start early, deliver the final draft with time to spare, make sure each person’s lawyer has time to advise fully, and avoid last-minute changes that restart the clock. Washington has no statutory waiting period like California’s seven-day rule, so the protection comes from practice rather than a statute.

Why a Washington Prenup Matters More Than People Expect

Washington is a community property state, but its divorce rule is broader than the label suggests. Under RCW 26.09.080, the court in a dissolution divides the parties’ property and liabilities, “either community or separate,” in a manner that is just and equitable, without regard to misconduct. The statute lists factors including the nature and extent of the community property, the nature and extent of the separate property, the duration of the marriage and the economic circumstances of each spouse.

In practice, this means a Washington court can award one spouse’s separate property to the other spouse. A house owned before the marriage, an inheritance or a family business is not automatically safe just because it is separate. For many clients, this is the strongest reason to sign a prenuptial agreement, and it is the point most often misunderstood.

Separate property income stays separate, with a large exception

Washington follows what is sometimes called the American rule for income from separate property. Under RCW 26.16.010 and 26.16.020, property owned before marriage or acquired by gift or inheritance, together with its rents, issues and profits, remains separate. That is the opposite of Idaho and Texas, where income from separate property is generally community.

The exception is large. Under Hamlin v. Merlino, 44 Wn.2d 851 (1954), and In re Marriage of Elam, 97 Wn.2d 811 (1982), when community labor is combined with separate real estate or an unincorporated business, the income can be treated as community unless it is contemporaneously segregated, and the community may have an equitable lien or right of reimbursement for its contributions. A prenuptial agreement can define how salary, business growth, reinvested earnings and contributions to separate property will be treated, which avoids expensive tracing later.

What a Washington Prenuptial Agreement Can Address

Washington couples commonly use prenuptial agreements to:

  • Identify each person’s separate property at the time of marriage and keep it separate, including appreciation and income.
  • Decide whether earnings during marriage will be community or separate, in whole or in part.
  • Protect an interest in a family business, professional practice or closely held company, and coordinate with any buy-sell agreement the business already has (see Washington business law).
  • Allocate responsibility for pre-marriage debts, student loans and business liabilities.
  • Address how the family home will be owned, and what happens to contributions from separate funds.
  • Provide a schedule of property transfers or payments on divorce, often increasing with the length of the marriage.
  • Set out rights at death, including waivers or minimum provisions, and coordinate with wills and trusts.

Maintenance provisions

Some agreements address maintenance (Washington’s term for spousal support under RCW 26.09.090). Whether and to what extent a Washington prenuptial agreement can waive maintenance has not been settled by controlling Washington authority. Any maintenance provision should be drafted conservatively, with an understanding that it will be tested under the Matson framework and may not be enforced exactly as written.

What the agreement cannot control

A prenuptial agreement cannot bind a court on child support or parenting arrangements. Washington courts set child support under the support schedule in chapter 26.19 RCW and decide parenting plans based on the child’s best interests. Provisions that attempt to limit support for a child or predetermine custody are not enforceable.

Financial Disclosure: Amount, Character and Value

Because procedural fairness under Matson requires full disclosure of the amount, character and value of the property involved, disclosure is the backbone of an enforceable Washington prenup. Holmes Law typically attaches schedules listing each party’s assets and liabilities with values, supported by recent statements, appraisals or business valuations where appropriate. Where exact values are not available, the schedule should say how the values were estimated. Income, expected inheritances, trust interests and business interests should also be described.

A disclosure schedule that is vague, incomplete or disputed invites the argument that the procedural prong was not satisfied. Good disclosure costs relatively little at signing and is very difficult to reconstruct years later.

Independent Counsel: Choosing Your Own Washington Prenuptial Agreement Attorney

Washington does not require each party to have a lawyer, but independent advice is part of the procedural fairness test. When one party has counsel and the other does not, the agreement is more vulnerable. Holmes Law represents only one party to a prenuptial agreement. The other partner should retain a separate Washington lawyer of his or her own choosing.

Voluntariness is about the circumstances of signing. Wedding invitations sent, a venue booked, family traveling and a draft delivered days before the ceremony all create pressure. The Bernard decision shows how those facts can undermine an agreement. The best practice is to begin negotiation months before the wedding and sign well in advance.

Estate Rights, Community Property Agreements and Retirement Plans

A prenuptial agreement is not only a divorce document. Washington does not have an elective share statute; instead, a surviving spouse owns one-half of the community property and may inherit under the decedent’s will or the intestacy statute. A prenup that keeps property separate therefore affects what passes at death, and it should be coordinated with each party’s will or revocable trust.

Watch for community property agreements. Under RCW 26.16.120, married couples can sign a community property agreement, often used to pass everything to the survivor at the first death. Such an agreement is terminated only by mutual assent or a final dissolution decree. In re Estate of Bachmeier, 147 Wn.2d 60 (2002), held that a unilateral inconsistent will does not revoke it, and RCW 11.11.010(7)(a)(iv) excludes community property agreements from the superwill statute. A community property agreement signed later can override the separate property plan a prenup created, so couples should not sign one without reviewing the prenup.

Retirement plans require special attention. Under 26 C.F.R. § 1.401(a)-20, Q&A-28, a waiver of spousal survivor benefits in a qualified retirement plan contained in a prenuptial agreement does not satisfy federal consent requirements. The waiver must be signed by the spouse, after the marriage, on the plan’s own form. A prenup should include an obligation to sign those forms after the wedding. See Washington estate planning for how the pieces fit together.

Couples Who Already Live Together, and Domestic Partners

Many Washington couples live together for years before marrying. Washington recognizes committed intimate relationships under Connell v. Francisco, 127 Wn.2d 339 (1995), and property acquired during such a relationship can be subject to equitable division even though the couple was not married. A prenuptial agreement should address property acquired before the wedding during cohabitation, not only property acquired after. State registered domestic partners under chapter 26.60 RCW are generally treated like spouses for these purposes, and an agreement can address the partnership as well.

Signing, Storage and Keeping the Agreement Effective

A Washington prenuptial agreement should be in writing, signed by both parties before the marriage, and acknowledged before a notary. Each party should keep a fully signed original or certified copy, together with the disclosure schedules and the lawyers’ certifications of advice. Where the agreement affects real property, recording a memorandum or the agreement itself can be considered.

Washington courts also look at how the parties actually behaved. When a spouse claims an informal agreement about the character of property, In re Marriage of Mueller, 140 Wn. App. 498 (2007), following Kolmorgan v. Schaller, 51 Wn.2d 94 (1957), requires clear and convincing evidence of the agreement and proof that the parties mutually observed it throughout the marriage. A written prenuptial agreement stands on firmer ground than an informal understanding, but conduct still matters. Couples who routinely mix separate and community funds, retitle separate assets into joint names or ignore the agreement’s procedures invite arguments about commingling, waiver or later agreements that changed the deal. Keeping separate accounts separate, documenting contributions and reviewing the agreement at major life events are the simplest ways to preserve its force.

If circumstances change after the wedding, the parties can amend the agreement by a written postnuptial agreement.

Frequently Asked Questions

Is a prenuptial agreement enforceable in Washington?

Yes, if it satisfies the two-prong test from Friedlander and Matson. The court asks whether it is substantively fair, and if not, whether it was procedurally fair, with full disclosure and voluntary execution on independent advice. The spouse seeking enforcement bears the burden.

Does Washington follow the Uniform Premarital Agreement Act?

No. Washington has not adopted the UPAA or the newer uniform act. Validity is governed by case law.

Can my separate property be awarded to my spouse in a Washington divorce?

Yes. RCW 26.09.080 allows the court to divide community and separate property in a just and equitable manner. A prenuptial agreement is the main way to change that result.

How far before the wedding should we sign?

There is no statutory deadline, but Bernard shows that last-minute drafts and limited review can defeat an agreement. Start months in advance and sign well before the ceremony.

Can we both use the same lawyer?

No. Holmes Law represents one party only. Independent advice for each party is part of the procedural fairness analysis.

Does a prenup waive my spouse’s rights in my 401(k)?

Not by itself. Federal regulations require the spouse to sign the plan’s waiver after the marriage.
