How Do Prenups Protect Business Interests?

If you own a business and you are about to marry, a prenuptial agreement can keep that company, and the value it gains over the years, firmly on your side of the ledger. For the many entrepreneurs and professionals building companies across Snohomish County, that protection can be the difference between a clean outcome and a contested fight over what the business is worth.

Why a Business Is at Risk Without Planning

Washington is a community property state, and that shapes everything about how a business is treated in a marriage. Under Washington law, property one spouse owns before the wedding, or receives by gift or inheritance, is separate property. Property acquired during the marriage generally belongs to both spouses as community property. Separate property is defined in RCW 26.16.010, and community property in RCW 26.16.030.

A business you owned before marriage starts out as your separate property. The problem is that businesses do not sit still. They grow, and that growth often comes from work you do during the marriage. When a spouse spends marriage-era time, labor, and skill building up a company, Washington courts may treat some of the increase in value as community property, even though the business itself began as separate. The community can develop a claim on the fruits of that effort. So a founder who assumes the company is untouchable because it predated the wedding can be surprised to learn that years of growth during the marriage may be partly on the table if the marriage ends.

What a Prenup Can Lock In

A prenuptial agreement lets a couple settle these questions in advance rather than leaving them to the default rules. The couple can agree in writing that the business remains one spouse's separate property, and, just as importantly, that its future appreciation stays separate too. That second piece is what makes a prenup so valuable for a business owner. Without it, the company's growth during the marriage is where a community claim usually forms. With a well-drafted agreement, the couple can say plainly that increases in the business's value, reinvested profits, and the owner's sweat equity all remain that spouse's separate property under RCW 26.16.010, rather than becoming community property under RCW 26.16.030.

A prenup can also address the practical realities that come with a closely held business. It can keep the other spouse from acquiring an ownership interest, address how a salary drawn from the business is treated, and provide certainty to business partners and investors who do not want a co-owner's divorce to disrupt the company. For a family business, or for a professional practice where outside ownership is restricted, that certainty can protect not just the couple but everyone who depends on the enterprise.

The Fairness Requirements That Make It Stick

A prenup only protects a business if it holds up, and in Washington there is no statute that decides that question. The controlling rules come from case law. The leading decision is In re Marriage of Matson, 107 Wn.2d 479 (1986), which established a two-part fairness test that courts still use.

The first part looks at substantive fairness: whether the agreement makes a fair and reasonable provision for the spouse who is not seeking to enforce it. If it does, the agreement generally stands. If the terms are one-sided, the court examines procedural fairness, which turns on two things. The spouses must have made full disclosure of the amount, character, and value of their property, and the agreement must have been entered into voluntarily, on independent advice, with each spouse understanding the rights being surrendered. The Washington Supreme Court applied this same framework in In re Marriage of Bernard, 165 Wn.2d 895 (2009), refusing to enforce an agreement that was both lopsided and pushed through on the eve of the wedding.

For a business owner, the lesson is concrete. Full disclosure means being candid about the value of the company, not shielding it behind vague descriptions. A business owner who hides the true worth of the enterprise, or who presents the agreement days before the ceremony when the other spouse has no real chance to review it, risks the very outcome the prenup was meant to prevent. The safer path is straightforward: give an honest picture of the business, allow plenty of time, and make sure each spouse can consult their own attorney. Ironically, the fairness the law demands is what makes the protection durable.

What a Prenup Will Not Cover

A prenup can do a great deal for a business, but it has limits. It cannot decide questions of child custody or child support ahead of time. Those decisions rest on a child's best interests as of the time they arise, and a court, not a contract, has the final say. So while a prenup can protect the company and its growth, it cannot pre-settle everything about a future family.

Protecting What You Built

You put years into building your business. A prenuptial agreement is a way to make sure that a change in your personal life does not put the enterprise, or the people who rely on it, at risk. Handled properly, with honest disclosure and enough time to do it right, a prenup lets a business owner marry with confidence rather than worry.
