Can a Spouse Be Left Out of a Will?

By Tyler Thompson

Leaving a spouse out of a will does not necessarily leave that spouse without inheritance rights. Iowa has an elective-share framework that must be considered alongside the document’s distribution provisions.

This is particularly important in a second marriage or blended family. A person may want to support a spouse while preserving property for children, but the plan needs to address both the desired result and the applicable protections.

The will is only part of the analysis

Section 633.236 recognizes the surviving spouse’s right to elect a statutory share when a married person domiciled in Iowa dies. The related provisions govern the election and its consequences.

Section 633.238 describes the property involved, including specified real property, personal property, and qualifying revocable-trust property, with conditions and exceptions. Reducing the rule to “one-third of everything” can obscure important details about ownership, obligations, and relinquished rights.

The first task is therefore to gather the will, relevant trust documents, property records, and any agreement addressing spousal rights. The calculation should follow review of the actual circumstances rather than a percentage applied to an informal family estimate.

A trust does not automatically remove the question

Imagine a person puts most assets in a revocable trust for adult children and leaves little under the will. It would be incomplete to examine only the probate account and conclude that the spouse has no meaningful rights. The statutory treatment of qualifying trust property requires attention too.

Likewise, an agreement said to waive inheritance rights needs review on its own terms. Do not assume that a signature on an unrelated property document answers every spousal-rights question.

During planning, ask how the proposed documents provide for the spouse and how the children’s intended interests fit with that arrangement. Be specific about the home, liquidity, and ongoing expenses. Those practical facts can affect whether a proposed plan is workable for the people involved.

After death, a surviving spouse should obtain advice promptly about any election and applicable deadlines. The family should avoid treating a sentence of exclusion as the end of the inquiry. The document expresses a wish; the legal review determines what rights and choices remain under Iowa law.
