✓ Verified September 2026

Iowa Surviving Spouse Rights exist because a will cannot cut a husband or wife out entirely. Every state protects a widow or widower with a share they may claim regardless of what the will says, plus allowances that come off the top before creditors and other heirs.

This guide gives the Iowa answer in plain English: what the elective share is, the deadline to claim it, whether trusts and joint accounts count, the homestead, exempt-property and family allowances, what happens when the marriage came after the will, and what forfeits the rights. All facts are from Iowa law, verified as of September 2026.

Iowa Surviving Spouse Rights: At a Glance

Here are the Iowa facts that decide most Iowa surviving spouse rights claims:

Elective share	Iowa Code § 633.236 gives the surviving spouse of a decedent domiciled in Iowa the right to take an elective share against the will. Under § 633.238(1), that share is one-third in value of all legal or equitable estates in real property the decedent possessed at any time during the marriage that were not sold on execution or other judicial sale and that the spouse has not relinquished in writing; all personal property that in the decedent’s hands as head of a family would be exempt from execution; and one-third of all other personal property not needed to pay debts and charges. It is not a percentage of a Uniform Probate Code style augmented estate.
Deadline to elect	Under Iowa Code § 633.237, the personal representative or trustee serves the surviving spouse with notice of the right to elect, and the spouse must file the election in writing with the clerk of court within 4 months after service of that notice. If no election is filed within those 4 months, it is conclusively presumed the spouse takes under the will, the intestate share, or the revocable trust. On application of the spouse or the spouse’s conservator filed before the 4 months expire, the court may extend the election period (§ 633.237). The clock runs from service of notice, not from the date of death.
Counts non-probate assets (augmented estate)	NO — Iowa does not use a Uniform Probate Code augmented estate. One category of non-probate property is reached: Iowa Code § 633.238(1)(d) adds one-third in value of property held in a trust over which the decedent was grantor and retained at death the power to alter, amend, or revoke, or waived or rescinded that power within one year of death. Section 633.238 excludes such trust property if the decedent created the trust after the marriage and each transfer into it (other than tangible personal property) carried the required written statement. Joint accounts, life insurance, beneficiary designations, and lifetime gifts are not generally pulled back in.
Community property state	NO — Iowa is a common law (separate property) state, so there is no automatic one-half community interest. The surviving spouse’s protection against disinheritance is the elective share under Iowa Code §§ 633.236–633.246, plus the homestead election, exempt personal property, and the spousal allowance.
Homestead allowance	Iowa has no flat dollar homestead allowance. Instead, Iowa Code § 633.240 lets the surviving spouse (in any estate where an election is filed, and in all intestate estates whether or not an election is filed) elect to receive a life estate in the homestead in lieu of the spouse’s one-third share of real property the decedent possessed during the marriage. The spouse making that election still takes the personal property rights in § 633.238(1)(b), (c), and (d). The election must be made and entered of record under § 633.245; failure to elect waives the homestead life estate. Homestead occupancy rights are also addressed in Iowa Code ch. 561.
Exempt property	Iowa sets no separate fixed dollar exempt property allowance. Iowa Code § 633.238(1)(b) passes to the electing spouse all personal property that in the decedent’s hands as head of a family would have been exempt from execution, and § 633.332 preserves that exempt character in the spouse’s hands. The dollar limits come from the general exemption statute, Iowa Code § 627.6 — for example, clothing, household furnishings, household goods, and musical instruments up to an aggregate 7000, and one motor vehicle up to 7000. Confirm current § 627.6 figures with the court or a licensed Iowa attorney.
Family allowance	Iowa Code § 633.374 directs the court, on application, to set off and order paid to the surviving spouse — as part of the costs of administration — enough of the decedent’s property, including assets held in a revocable trust the decedent settled to the extent estate assets are insufficient, for support of the spouse for 12 months following the death, and for support of the decedent’s dependents living with the spouse for that same period. The personal representative must mail written notice of this right, and the spouse applies to the court within 4 months of service of that notice. The amount is what the court finds reasonable; the allowance is a matter of right and is separate from the elective share.
Court / filing	The Iowa District Court sitting in probate for the county where the estate is administered; the election is filed with the clerk of that court (Iowa Code §§ 633.237, 633.245). — An election to take the elective share — commonly captioned an election to take against the will (or spousal election) — filed in writing with the clerk of court under Iowa Code § 633.237 and entered of record under § 633.245. A separate election to receive a life estate in the homestead is filed under § 633.240, and an application for spousal allowance under § 633.374.

Why the Will Cannot Disinherit a Spouse in Iowa

The law treats marriage as an economic partnership. A spouse who spent decades contributing to a household is not left to the mercy of a will written in anger, under pressure, or decades ago. In separate-property states the protection is the elective share: a fixed fraction of the estate the surviving spouse may take instead of whatever the will provides.

In community property states it is built in — half of everything acquired during the marriage already belongs to the survivor and never passes under the will at all. Iowa uses one of those two systems, and the table above says which.

The right is personal to the spouse and must be claimed. Nothing happens automatically: a surviving spouse who does nothing takes what the will gives, even if that is nothing. The election has a deadline, it is filed in the probate court, and it is the single Iowa surviving spouse rights fact that a grieving spouse most often learns too late.

The Iowa Elective Share

Iowa Code § 633.236 gives the surviving spouse of a decedent domiciled in Iowa the right to take an elective share against the will.

Under § 633.238(1), that share is one-third in value of all legal or equitable estates in real property the decedent possessed at any time during the marriage that were not sold on execution or other judicial sale and that the spouse has not relinquished in writing; all personal property that in the decedent’s hands as head of a family would be exempt from execution;

and one-third of all other personal property not needed to pay debts and charges.

It is not a percentage of a Uniform Probate Code style augmented estate.

The deadline: Under Iowa Code § 633.237, the personal representative or trustee serves the surviving spouse with notice of the right to elect, and the spouse must file the election in writing with the clerk of court within 4 months after service of that notice.

If no election is filed within those 4 months, it is conclusively presumed the spouse takes under the will, the intestate share, or the revocable trust. On application of the spouse or the spouse’s conservator filed before the 4 months expire, the court may extend the election period (§ 633.237). The clock runs from service of notice, not from the date of death.

What counts: NO — Iowa does not use a Uniform Probate Code augmented estate. One category of non-probate property is reached: Iowa Code § 633.238(1)(d) adds one-third in value of property held in a trust over which the decedent was grantor and retained at death the power to alter, amend, or revoke, or waived or rescinded that power within one year of death.

Section 633.238 excludes such trust property if the decedent created the trust after the marriage and each transfer into it (other than tangible personal property) carried the required written statement. Joint accounts, life insurance, beneficiary designations, and lifetime gifts are not generally pulled back in.

Community property: NO — Iowa is a common law (separate property) state, so there is no automatic one-half community interest. The surviving spouse’s protection against disinheritance is the elective share under Iowa Code §§ 633.236–633.246, plus the homestead election, exempt personal property, and the spousal allowance.

Allowances the Spouse Gets on Top of the Will

Homestead: Iowa has no flat dollar homestead allowance. Instead, Iowa Code § 633.240 lets the surviving spouse (in any estate where an election is filed, and in all intestate estates whether or not an election is filed) elect to receive a life estate in the homestead in lieu of the spouse’s one-third share of real property the decedent possessed during the marriage.

The spouse making that election still takes the personal property rights in § 633.238(1)(b), (c), and (d). The election must be made and entered of record under § 633.245; failure to elect waives the homestead life estate. Homestead occupancy rights are also addressed in Iowa Code ch. 561.

Exempt property: Iowa sets no separate fixed dollar exempt property allowance. Iowa Code § 633.238(1)(b) passes to the electing spouse all personal property that in the decedent’s hands as head of a family would have been exempt from execution, and § 633.332 preserves that exempt character in the spouse’s hands.

The dollar limits come from the general exemption statute, Iowa Code § 627.6 — for example, clothing, household furnishings, household goods, and musical instruments up to an aggregate 7000, and one motor vehicle up to 7000. Confirm current § 627.6 figures with the court or a licensed Iowa attorney.

Family allowance: Iowa Code § 633.374 directs the court, on application, to set off and order paid to the surviving spouse — as part of the costs of administration — enough of the decedent’s property, including assets held in a revocable trust the decedent settled to the extent estate assets are insufficient, for support of the spouse for 12 months following the death,

and for support of the decedent’s dependents living with the spouse for that same period.

The personal representative must mail written notice of this right, and the spouse applies to the court within 4 months of service of that notice. The amount is what the court finds reasonable; the allowance is a matter of right and is separate from the elective share.

Married After the Will Was Signed

UNVERIFIED as a distinct statute — Iowa’s probate code contains no located pretermitted or omitted spouse section giving an automatic intestate-style share to a spouse married after the will was signed. Marriage after execution does not by itself revoke an Iowa will; Iowa Code § 633.271 addresses only divorce or dissolution.

In practice the later-married, unmentioned spouse’s remedy is the elective share under Iowa Code §§ 633.236–633.238, claimed within the § 633.237 4-month window. Anyone in this situation should confirm the point with the probate court or a licensed Iowa attorney.

Waiver and Disqualification in Iowa

Iowa Code § 633.238(1) repeatedly conditions the elective share on there being no “express written relinquishment of right” by the surviving spouse, so a signed written waiver is the mechanism. Premarital waivers are governed by Iowa Code ch. 596: § 596.4 requires the agreement to be in writing and signed by both parties, effective on marriage and enforceable without consideration.

Under § 596.8 an agreement is unenforceable if the party against whom enforcement is sought did not execute it voluntarily, or did not have fair and reasonable disclosure of the other party’s property and financial obligations, or if it is unconscionable. Independent counsel is not made a statutory prerequisite.

What forfeits the rights: Verified statutory grounds are narrow. Iowa Code § 633.535 bars a person who intentionally and unjustifiably causes or procures the decedent’s death from taking any property, benefit, or interest by reason of the death, whether under a will, intestacy, title registration, or non-testamentary instrument; the property passes as if that person predeceased.

Iowa Code § 633.271 governs the effect of divorce or dissolution on will provisions for a former spouse. A merely pending dissolution does not end the marriage, so the person is still a surviving spouse until a decree issues. Rights can also be lost by express written relinquishment (§ 633.238) or by failing to elect in time (§ 633.237). No Iowa abandonment or desertion forfeiture statute was located — UNVERIFIED.

If there is no will: With no will, Iowa Code § 633.211 gives the surviving spouse the entire estate when the decedent left no issue or only issue who are also the spouse’s, while Iowa Code § 633.212 gives the spouse one-half of the real property possessed during the marriage, the exempt personal property,

and one-half of other personal property (with a statutory minimum make-up) when some issue are not the spouse’s.

The Iowa dying-without-a-will guide linked below covers that in full.

Other Iowa rules: Several Iowa features are unusual. The share reaches real property the decedent possessed at any time during the marriage, not merely property owned at death — a remnant of Iowa’s old dower/curtesy distributive share. There is no sliding scale by length of marriage. The homestead life estate election under Iowa Code § 633.240 substitutes for the one-third real property share while preserving the personal property rights.

Iowa Code § 633.238 reaches revocable trust assets, with a carve-out for trusts created after the marriage where each funding transfer carried the required written notice. Iowa Code § 633.242 makes the right of election personal to the spouse, and § 633.244 allows a court election for an incompetent spouse. Deadlines run from service of notice, so watch the mail from the personal representative.

Mistakes That Cost a Surviving Spouse in Iowa

The first mistake is waiting. The election to take the statutory share has a deadline that runs from death or from the will’s admission, and the probate court cannot extend it for a spouse who did not know. The second is assuming the will is the whole picture.

A spouse who was left “the house” may be entitled to considerably more under the Iowa surviving spouse rights rules — and may also be entitled to allowances the will never mentions.

The third mistake is signing something in the first weeks. A release, a family settlement, or a disclaimer offered by another heir can waive rights the spouse did not know they had. The last is overlooking a prenuptial agreement.

If one exists, it may have waived the elective share — but only if it met the state’s requirements for disclosure and fairness at the time, which is a question a lawyer should answer before anyone relies on it.

What to Expect When You Claim Iowa Surviving Spouse Rights

Claiming Iowa surviving spouse rights is a filing inside the probate case, not a separate lawsuit. The surviving spouse files the election and any allowance requests with the court, the personal representative calculates the estate the share is measured against, and the court resolves any dispute over what counts.

Where the will already gives the spouse more than the statutory share, the election is unnecessary and most spouses do not file one.

Two things surprise people. The first is how much depends on the calendar — the election deadline is short in some states and runs whether or not the spouse knew. The second is that the allowances are separate from the share and are paid first, ahead of creditors, which is often what keeps a surviving spouse in the home during the months the estate takes to settle.

Key Takeaways: Iowa Surviving Spouse Rights

The will cannot disinherit you: Iowa surviving spouse rights guarantee a share the spouse may claim no matter what the will says.
You must elect: Iowa surviving spouse rights are not automatic; the statutory share is claimed by a filing in the probate court.

Community property is different: where it applies, half is already the survivor’s, and Iowa surviving spouse rights are about the other half.
A late marriage changes the will: a spouse married after the will was signed usually takes an intestate share under Iowa surviving spouse rights.
Prenups can waive: Iowa surviving spouse rights can be given up in a prenuptial or postnuptial agreement, but only one that met the state’s disclosure rules.
Separation can forfeit: a pending divorce or abandonment can end Iowa surviving spouse rights in some states before the death.
Sign nothing early: a release or disclaimer offered by another heir can waive Iowa surviving spouse rights the spouse never knew about.
Compare before you elect: Iowa surviving spouse rights are worth claiming only when the statutory share exceeds what the will gives.
The intestate share is separate: when there is no will, Iowa surviving spouse rights are set by the intestacy rules on the companion guide.

Quick Answers: Iowa Surviving Spouse Rights

What are Iowa Surviving Spouse Rights if the will leaves the spouse nothing?

A statutory share — commonly a third to a half of the estate — plus allowances paid ahead of creditors. Iowa Surviving Spouse Rights exist precisely for this case, but they must be claimed by a filing.

How long does a spouse have to claim Iowa Surviving Spouse Rights?

A fixed period after death or after the will is admitted, set by statute. Missing it forfeits the statutory share, which is the most common way Iowa surviving spouse rights are lost.
