How Do Prenups Work With Real Estate?

Real estate is often the biggest and most emotionally charged asset a couple owns, whether it is a house one spouse bought years before the wedding or a home they plan to buy together. A prenuptial agreement can settle in advance how that property is treated.

Separate Property and the Home You Bring Into the Marriage

If you own a house before you marry, Washington law treats it as your separate property. A spouse may manage, lease, sell, convey, encumber, or devise separate property without the other spouse joining in, as fully as if they were unmarried. See RCW 26.16.010. In principle, then, a home you owned before the wedding stays yours. The complication is what happens during the marriage. If community funds, meaning income earned by either spouse during the marriage, are used to pay the mortgage, cover improvements, or otherwise build equity, the community can acquire an interest in what started as separate property. Over the years, the line between what is separate and what has become community can blur, and sorting it out at divorce can be expensive and contentious.

A prenuptial agreement is the tool that keeps that line clear. Two people can agree that a specific property will remain one spouse's separate property, and that even mortgage payments or improvements funded during the marriage will not convert it into community property or create a community claim against it. Because the separate property protections in RCW 26.16.010 depend on the property's character, an agreement that fixes that character in advance prevents the slow drift toward community ownership that otherwise happens.

Property You Buy Together After the Marriage

A prenup can also decide how jointly acquired real estate will be treated. Property acquired during the marriage is generally community property under RCW 26.16.030, but couples can agree to something different: that a future home will be owned in specific shares, that one spouse's separate down payment will be repaid before any equity is divided, or that a vacation property will remain separate even though it is purchased during the marriage. These arrangements are especially useful when the spouses are contributing unequal amounts, or when one spouse wants to preserve an inheritance or business proceeds used toward a purchase.

It is worth understanding what a prenup does not change about community real estate. Washington law requires both spouses to join in selling, conveying, or encumbering community real property, meaning both must sign the deed or instrument and both must acknowledge it. See RCW 26.16.030. The same statute requires both spouses to join in purchasing or contracting to purchase community real estate. This joinder requirement is a protection built into the law for property that is community in character. A prenup can decide whether a given property is community or separate in the first place, which in turn determines whether that joinder rule applies, but where property remains community, both spouses generally still need to sign off to convey or encumber it.

Keeping the Agreement Enforceable

A prenup dealing with real estate is only as good as its enforceability, and Washington has no statute setting those standards. The controlling authority is case law, principally In re Marriage of Matson, 107 Wn.2d 479 (1986). Under Matson, a court first asks whether the agreement made a fair and reasonable provision for the spouse who is not seeking to enforce it. If it did, that can be enough to uphold the agreement. If it did not, the court looks closely at the process behind the signing: whether both parties disclosed their assets fully, whether each understood the rights they were giving up, whether each had a genuine opportunity for independent legal advice, and whether the agreement was signed voluntarily rather than under time pressure or coercion.

Real estate provisions draw this scrutiny because a house is often a spouse's single largest financial expectation. If one spouse gives up any community claim to a home worth hundreds of thousands of dollars, a court will want to see that they knew what they were agreeing to and did so freely. Full disclosure of the property and its value, an honest explanation of the community interest being waived, separate counsel for each party, and unhurried signing well before the wedding all help the provision survive a later challenge.

Recording, Titling, and Following Through

Even a solid prenup benefits from consistent follow-through. How title is held, how the mortgage is paid, and how improvements are funded should match what the agreement says. If the agreement calls a property separate but the couple later refinances into both names and pays from a joint account, the paper trail can undercut the intended result. Keeping records of separate funds used for down payments and improvements, and titling property consistently with the agreement, protects the arrangement over time.

Homeowners across Snohomish County, from Everett to Marysville to the smaller communities in between, often bring real estate into a marriage or plan to buy together, and a prenuptial agreement can spare them a great deal of uncertainty later.
