What Is a Prenuptial Agreement?
A prenuptial agreement (or “prenup”) is a legal contract between two people who plan to marry. Essentially, it outlines how assets, debts, income, and financial matters will be handled during marriage and in case of divorce or death.
In Washington State, enforceable prenups can override default community property laws. Consequently, these agreements provide protection for both parties. While every couple has different financial circumstances, Weintraub Law Office PLLC drafts clear, amicable agreements customized to your specific needs. In practice, these documents act as a financial roadmap for your long-term goals.
What a Washington Prenup Can and Cannot Cover
Washington prenuptial agreements can settle financial and property matters, but state law places firm limits on what they can control.
| A Washington Prenup CAN Address | A Washington 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’re entering your first marriage or blending families, a prenuptial agreement offers more than just legal protection. It offers peace of mind. Specifically, this proactive step provides several essential benefits for your partnership:
- Clarify financial expectations during marriage
- Protect premarital property, inheritances, business interests, and future earnings
- Define spousal support expectations in advance
- Shield one spouse from the other’s debts
- Ensure stability for children from prior relationships
- Reduce the risk of costly, high-conflict divorce proceedings
However, if you do not have a prenup, Washington’s community property laws determine how courts divide assets. Consequently, these laws may distribute property in ways that do not reflect your personal wishes. Therefore, a well-drafted agreement serves couples throughout the Puget Sound region by replacing legal uncertainty with a clear, personalized plan.
| 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. |
| Inheritances | 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 the substantive fairness of the agreement, including whether it 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 State courts do not enforce provisions related to child support or child custody and parenting issues.
Why Couples Choose Weintraub Law Office for Their Prenup
Prenuptial agreements are a specialized area of Washington law. Our lead attorney, Boaz Weintraub, co-authored the Prenuptial Agreements chapter of the Washington State Bar Association’s Family Law Deskbook and brings substantial experience to preparing both prenuptial and postnuptial agreements.
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 on every agreement — 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.
Our Prenup Process and Timeline
We streamline the process for couples throughout King and Snohomish Counties through these six steps:
- Step 1: Initial Consultation to discuss your goals
- Step 2: Questionnaire to gather background information
- Step 3: Online appointment to review terms
- Step 4: Drafting and review (1–2 week turnaround)
- Step 5: Review by your partner’s attorney and negotiation as needed
- Step 6: Finalization, signing, and notarization
By following these steps, we work efficiently while allowing enough time for thoughtful review.
Prenuptial Agreement Fees
We handle prenuptial agreements on an estimated-fee basis. Total cost depends on factors such as:

To ensure transparency, we provide clear fee expectations during your consultation and keep clients informed if scope changes.

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 plan 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. It makes an agreement far more likely to survive a court challenge.
How much does a prenuptial agreement cost?
We handle prenups on an estimated-fee basis depending on complexity, and provide clear fee expectations during your complimentary consultation.
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 and may address many of the same property, debt, and financial issues. Learn more on our postnuptial agreements guide page.
