Clear, Enforceable Prenuptial Agreements in Washington State
Prenuptial agreements are not about conflict; they are about clarity and planning. At Weintraub Law Office PLLC, we help couples create clear, enforceable agreements that protect each partner’s financial interests while reducing the potential for future conflict. Our lead attorney, Boaz Weintraub, co-authored the prenuptial agreements chapter of the Washington State Bar Association’s Family Law Deskbook, the reference guide used by family law attorneys across the state.
We offer complimentary consultations to discuss your goals, timeline, and expected costs.
What Is a Prenuptial Agreement?
A Washington prenuptial agreement, or “prenup,” is a written contract between two people who plan to marry. It can address how assets, debts, income, spousal maintenance, premarital property, and other financial matters will be characterized and handled during the marriage and upon divorce. For couples who lived together first, it can also address property rights that may have arisen from cohabitation before the marriage, including any committed intimate relationship. A prenuptial agreement may also complement estate planning by addressing how property is characterized upon death and whether certain inheritance rights are waived, preserved, or transferred. However, a prenuptial agreement is not a substitute for a will, trust, or comprehensive estate plan.
In Washington State, a properly drafted and enforceable prenuptial agreement can modify the default community-property rules and address how spousal maintenance may be handled, helping protect both parties’ financial expectations. Every couple’s financial circumstances are different, and we draft clear, amicable agreements customized to your specific needs.
What a Prenup Can and Cannot Cover
A Washington prenuptial agreement can settle financial and property matters, but state law places firm limits on what it can control.
| A Prenup CAN Address | A Prenup CANNOT Control |
|---|---|
| Division of property and debts at divorce or death | Child custody and the parenting plan |
| Characterizing assets as separate vs. community property | Child support obligations |
| Spousal support (alimony) — a set amount or a formula | Anything that limits a parent’s right to go to court over the children |
| Protecting a business and its future earnings | Anything that violates Washington law or public policy |
| Debt brought into the marriage by either spouse | Provisions designed to encourage divorce |
| Inheritance rights, incl. children from a prior relationship | Non-financial “lifestyle” clauses (generally unenforceable) |
Important: Even if both partners agree on custody or child-support terms, a Washington court is not bound by them — those issues are decided under state law at the time of divorce, in the best interests of the children.
Why You Need a Prenuptial Agreement in Washington State
Whether you are entering a first marriage or blending families, a prenuptial agreement offers more than legal protection — it offers peace of mind. This proactive step:
- Clarifies financial expectations during the marriage
- Protects premarital property, inheritances, business interests, and future earnings
- Defines spousal support expectations in advance
- Shields one spouse from the other’s debts
- Provides stability for children from prior relationships
- Reduces the risk of costly, high-conflict divorce proceedings
Without a prenup, Washington’s community property laws determine how a court divides assets — often in ways that do not reflect your personal wishes.
| Financial Feature | With Your Custom Prenup | Without a Prenup (WA Law) |
|---|---|---|
| Asset Division | You decide how assets are split. | Courts divide assets by community property rules. |
| Inheritance | Defined protection as separate property. | Risk of unintended “commingling” with marital assets. |
| Business Interests | Protect ownership and future business earnings. | Interests and earnings may be subject to court division. |
| Debts & Liability | Shields you from a partner’s prior debts. | Subject to 50% liability for community debts. |
| Legal Process | Clear, streamlined, and amicable. | Higher risk of costly, high-conflict divorce. |
Are Prenuptial Agreements Enforceable in Washington?
Yes, when properly prepared. Washington courts apply a two-part test, and the spouse seeking to enforce the agreement carries the burden of proving its validity.
1. Substantive Fairness — The court first evaluates whether the agreement makes fair and reasonable provision for the spouse not seeking enforcement. If it does, the agreement is generally enforceable and the inquiry ends.
2. Procedural Fairness — If the agreement is not substantively fair, it may still be enforced if it was entered into fairly. This generally requires full disclosure of the amount, character, and value of the property and debts involved; voluntary signing; adequate opportunity to obtain independent legal advice; and knowledge of the legal rights being affected.
Please note: Washington courts do not enforce provisions related to child support or child custody and parenting issues. For more information, see RCW 26.09, which governs dissolution of marriage in Washington.
Why Couples Choose Weintraub Law Office for Their Prenup
Prenuptial agreements are a specialized area of Washington law, distinct from general family practice. We focus on getting the details right — the disclosure, the drafting, and the procedural safeguards that determine whether an agreement holds up if it is ever challenged.
Focused on an enforceable agreement
We build each agreement around your goals, with the aim of making it enforceable. Because substantive fairness is never guaranteed, we work to ensure the procedural safeguards Washington courts look for — full financial disclosure, adequate review time, and an opportunity for each party to obtain independent counsel — so your agreement is well positioned if it is ever challenged.
Collaborative, not adversarial
A prenup shouldn’t start a marriage with a fight. We invite collaboration with your fiancé or their attorney, protecting each partner’s interests while keeping the process amicable and respectful.
Responsive and efficient
We offer fast turnaround and prompt communication, so your agreement moves forward without unnecessary delay — and with enough time for thoughtful review before your wedding date.

Prenuptial Agreement Fees
We provide a clear fee estimate after your consultation, once we understand what your situation involves. Costs depend on the complexity of the agreement and the amount of revision required — including, when we are reviewing an agreement another attorney has drafted, how that agreement is written. We will always discuss fees with you before any additional work begins, so you are never surprised by an invoice.
Frequently Asked Questions
Are prenuptial agreements enforceable in Washington State?
Yes, when properly prepared. A Washington court will enforce a prenup that is substantively fair to both parties or, if not, was entered into with full financial disclosure, voluntarily, and with adequate opportunity for each party to consult independent counsel.
Can a prenup decide child custody or child support?
No. Washington courts decide parenting issues and child support under state law at the time of divorce, based on the best interests of the children. Parenting or support terms in a prenup are not binding on the court.
Do both partners need their own lawyer?
It isn’t strictly required, but it is strongly advised. Separate counsel for each party helps show that the agreement was entered voluntarily and with an opportunity to understand its legal consequences, making it far more likely to survive a court challenge.
How much does a prenuptial agreement cost?
We provide a clear fee estimate after your complimentary consultation, once we understand what your agreement involves. Cost depends on the complexity of the agreement and the amount of revision required, and we discuss fees with you before any additional work begins.
What’s the difference between a prenup and a postnup?
A prenuptial agreement is signed before the wedding; a postnuptial agreement is signed after marriage. Both address the same property, debt, and financial issues.
Postnuptial Agreements
A postnuptial agreement addresses the same financial and property issues as a prenup — the only difference is timing. A prenup is signed before the wedding; a postnuptial agreement is signed after a couple is already married.
A postnup can make sense when circumstances change after the wedding — for example, a business grows significantly during the marriage, one spouse receives a large inheritance they want to keep separate, or a couple wants to put a sound agreement in place after a wedding that came together too quickly for a proper prenup. The same Washington enforceability rules described above apply.
If you think a postnuptial agreement may fit your situation, we are glad to discuss it during your consultation.
Cohabitation Agreements for Unmarried Couples
A cohabitation agreement is for couples who live together but are not married — no marriage is involved. It clarifies property ownership and sets out how property and debts would be divided if the relationship ends.
This matters in Washington because a court may find that a couple in a long-term, marriage-like relationship was in a “committed intimate relationship” — formerly called a “meretricious relationship” — and equitably divide property that would have been community property had the parties been married. A committed intimate relationship, however, does not create a right to spousal maintenance, and separate property is not subject to division. A cohabitation agreement lets an unmarried couple set their own terms instead of leaving that to a court. We prepare these agreements on request.
