Iowa Will Contest Process: How Contested Wills Work (2026)

Sarah Ingles, REALTOR® SRES® · Fathom Realty

A will contest is a formal legal challenge to the validity of a deceased person's will. Iowa will contests are relatively rare but significant when they happen — they pause probate, tie up real property for months or years, and can cost the estate tens of thousands in legal fees. Here's how Iowa's process actually works and what executors, heirs, and REALTORS® need to know.

Who Can Contest an Iowa Will

Iowa Code § 633.308 allows a will contest only by "interested persons" — meaning people who would inherit differently under a prior will, under Iowa intestate succession, or as a creditor of the estate. A distant cousin or family friend generally cannot contest.

Grounds for Contesting an Iowa Will

Iowa recognizes four main grounds:

1. Lack of testamentary capacity. The person who made the will (the testator) was not mentally competent at the time of signing. Common in contests involving late-stage dementia or hospitalization.

2. Undue influence. Someone pressured the testator into changes that don't reflect their true wishes. Typically involves a caregiver, family member, or advisor who stood to benefit from the changes.

3. Fraud or forgery. The signature is forged, or the testator was tricked about what they were signing.

4. Improper execution. Iowa requires 2 witnesses plus the testator's signature. Wills that don't follow formal execution requirements can be voided.

The Iowa Contest Timeline

1. Will offered for probate (standard probate begins) 2. Contest filed — the challenger files a formal petition in the district court where probate is open. Iowa has strict deadlines (typically within 4 months of the appointment of executor, though statutes vary). 3. Discovery phase — both sides exchange medical records, witness statements, handwriting analysis, and prior drafts of the will. Can take 6-18 months. 4. Settlement or trial — most Iowa will contests settle rather than go to trial. A contested trial can add another 6-12 months. 5. Final order — the court either upholds the will, strikes the contested portions, or voids the will entirely.

What Happens to Real Property During a Contest

This is the question that matters most for heirs and REALTORS®. During an active will contest:

For Iowa executors dealing with a contested estate, the #1 priority is protecting the real property from loss during the contest window.

How Much Does an Iowa Will Contest Cost?

Contest costs are typically paid from the estate (if the contest is in good faith) and can easily run $15,000 to $75,000 in attorney fees for a moderately complex case. Full trials with expert witnesses (psychiatrists testifying about capacity, handwriting experts testifying about signatures) can exceed $100,000.

Because contests diminish the estate, many Iowa families settle rather than litigate — often splitting the disputed share 60/40 or 70/30 rather than fighting for 100%.

How Executors Protect the Estate During a Contest

1. Immediately move the home to vacant home insurance. The decedent's homeowner policy stops covering, and most carriers won't cover a vacant home on the original policy. 2. Winterize and secure the property. Turn off water, maintain heat to 55°F minimum in winter, change locks, forward mail. 3. Hire a probate REALTOR® for a pre-listing insurance review. As a REALTOR® with a CPCU insurance background, I evaluate whether the home is insurable under current conditions, which matters enormously when eventual sale comes. 4. Keep clear accounting. Every dollar spent on the estate property should be tracked for reimbursement. 5. Communicate regularly with all heirs and contestants. Most contest escalation comes from feeling excluded, not from actual disputes.

Frequently Asked Questions

Q: How long do you have to contest a will in Iowa? A: Iowa generally requires a will contest to be filed within 4 months of the appointment of the executor (or within a shorter window set by the court's notice). Exact deadlines depend on the specific case and the type of contest. Miss the deadline and the contest is barred.

Q: Can I sell an Iowa probate house during a will contest? A: Usually only with court authorization and agreement from the contestants (or a court order overriding disagreement). Most contested houses sit vacant during the litigation.

Q: What is undue influence in an Iowa will contest? A: Undue influence is when someone pressures the testator into will changes that don't reflect their true wishes. Iowa courts look at factors like the influencer's relationship to the testator, their opportunity to exert pressure, the testator's vulnerability, and whether the will disposes of property unusually.

Q: How much does it cost to contest a will in Iowa? A: Iowa will contests typically cost $15,000 to $75,000 in attorney fees for a moderately complex case. Full trials with expert witnesses can exceed $100,000. Contest costs are usually paid from the estate if the contest is brought in good faith.
