Contest a Will in Iowa: At a Glance
Here are the Iowa facts that decide whether you can contest a will in Iowa:
| Deadline to contest | The later of (a) 4 months from the date of the second publication of notice of admission of the will to probate, or (b) 1 month following the mailing of notice to all heirs of the decedent and devisees under the will whose identities are reasonably ascertainable, at their last known addresses — Iowa Code § 633.309. The same period applies to a joined claim for tortious interference with inheritance. If the will is admitted without administration, the notice/limitation provisions of Iowa Code § 633.305 govern the publication and mailing that start the clock. |
| What starts the clock | Second publication of the notice of admission of the will to probate (Iowa Code §§ 633.304, 633.305) and, alternatively, the mailing of that notice to reasonably ascertainable heirs and devisees — whichever produces the later cutoff. The clock is NOT run from the date of death. Objections may also be filed before the will is admitted, under Iowa Code § 633.310. |
| Who can contest | Any “interested person” may petition to set aside the probate of a will — Iowa Code § 633.308. “Interested person” is defined at Iowa Code § 633.3(21) as heirs, devisees, children, spouses, creditors, beneficiaries, and any others having a property right in or claim against the estate. In practice this means intestate heirs who would take if the will fails, beneficiaries under a prior will, beneficiaries whose share is reduced by the challenged will, and creditors with a pecuniary interest. The contestant must have a direct pecuniary interest that would be affected by the outcome. |
| No-contest clause | YES — enforced, with a good-faith AND probable-cause exception, and the contestant bears the burden of proving both. Iowa follows Restatement (Third) of Property: Wills and Other Donative Transfers § 8.5. In Felten v. Hoffman (In re Estate of Felten), No. 24-1053 (Iowa, decided November 2025), the Iowa Supreme Court held the challenger must prove, under a totality-of-the-circumstances test, both (1) subjective good faith — an honest belief the challenge was right — and (2) objective probable cause as defined in Restatement (Third) of Property § 8.5 cmt. c. Failing either prong, the clause is enforced and the contestant forfeits the bequest. Earlier authority: In re Cocklin’s Estate, 236 Iowa 98, 17 N.W.2d 129 (1945). |
| What the filing is called | “Petition to set aside probate of will” — a written petition filed in the existing probate proceedings in the district court where the will was admitted, stating the grounds (Iowa Code § 633.308). Before admission, the equivalent filing is “objections to probate of will” under Iowa Code § 633.310. Both are commonly called a will contest. |
| Court | The Iowa District Court sitting in probate for the county in which the will was admitted to probate (Iowa Code §§ 633.10, 633.308). Iowa has no separate surrogate’s or orphans’ court; probate is a division of the general-jurisdiction district court, and clerk of court offices are county-based. |
| Jury trial | YES — Iowa Code § 633.311 provides that an action objecting to the probate of a proffered will, or to set aside a will, is triable in the probate court as an action at law, and the rules of civil procedure governing law actions, including demand for jury trial, apply. Iowa Code § 633.33 likewise classifies actions to set aside or contest wills as triable in probate as law actions (all other probate matters are tried in equity). A jury demand must be made as provided in the Iowa Rules of Civil Procedure (Iowa R. Civ. P. 1.902). |
| Typical cost | UNVERIFIED — Iowa does not publish official cost data for contested will cases. The court filing fee for a probate petition and related costs are set by Iowa Code § 633.31; attorney fees in a contest are separately negotiated and are not governed by the statutory estate-attorney fee schedule in Iowa Code § 633.197. Contested cases that go to jury trial cost substantially more than those resolved early. Check with the clerk of the Iowa district court in the county of administration or a licensed Iowa attorney for current figures. |
The Deadline to Contest a Will in Iowa
The window is short in some states and long in others, and it is measured from a specific event rather than from the day you learned about the will. That is why the first thing to find out is the date the will was admitted and whether you received formal notice. If the deadline has not run, everything else on this page is available to you.
If it has, the remaining options are narrow and usually involve proving you never got the notice the law required.
Grounds to Contest a Will in Iowa
Lack of testamentary capacity (testator did not know the nature of the instrument, the nature and extent of the property, the natural objects of bounty, or the distribution desired); undue influence (four elements: susceptibility, opportunity, disposition to influence unduly, and a result clearly the effect of undue influence); fraud; duress; improper/defective execution under Iowa Code § 633.279 (writing, signed by testator,
declared to and signed by two competent witnesses in the testator’s presence); forgery; revocation (Iowa Code § 633.284); and mistake.
Tortious interference with inheritance must be joined with a timely will contest under Iowa Code § 633.309(2).
Who has to prove what: The contestant (the party challenging the will) carries the burden of proof, by a preponderance of the evidence, on lack of testamentary capacity, undue influence, fraud, and duress. Iowa courts have declined to require clear and convincing evidence for undue influence in will contests, while applying heightened substantive scrutiny to the four required elements.
The proponent bears the initial burden of proving due execution under Iowa Code § 633.293; a self-proved will under Iowa Code § 633.279(2) satisfies that showing without witness testimony.
Where a confidential or fiduciary relationship exists, a presumption of undue influence can arise, and the person benefiting must rebut it by clear, satisfactory, and convincing evidence that they acted in good faith throughout and that the grantor acted freely, intelligently, and voluntarily — this presumption is most commonly applied to inter vivos transfers, and in will contests Iowa courts generally require the confidential relationship plus additional supporting evidence.
Who Can Contest a Will in Iowa
Any “interested person” may petition to set aside the probate of a will — Iowa Code § 633.308. “Interested person” is defined at Iowa Code § 633.3(21) as heirs, devisees, children, spouses, creditors, beneficiaries, and any others having a property right in or claim against the estate.
In practice this means intestate heirs who would take if the will fails, beneficiaries under a prior will, beneficiaries whose share is reduced by the challenged will, and creditors with a pecuniary interest. The contestant must have a direct pecuniary interest that would be affected by the outcome. Being unhappy with the will is not standing; losing something because of it is.
Check the earlier will and the intestate rules for Iowa before filing, because they decide whether you are an interested person.
No-Contest Clauses in Iowa
YES — enforced, with a good-faith AND probable-cause exception, and the contestant bears the burden of proving both. Iowa follows Restatement (Third) of Property: Wills and Other Donative Transfers § 8.5. In Felten v. Hoffman (In re Estate of Felten), No.
24-1053 (Iowa, decided November 2025), the Iowa Supreme Court held the challenger must prove, under a totality-of-the-circumstances test, both (1) subjective good faith — an honest belief the challenge was right — and (2) objective probable cause as defined in Restatement (Third) of Property § 8.5 cmt. c. Failing either prong, the clause is enforced and the contestant forfeits the bequest.
Earlier authority: In re Cocklin’s Estate, 236 Iowa 98, 17 N.W.2d 129 (1945).
The Steps to Contest a Will in Iowa
Step one is the deadline check above. Step two is evidence: the medical records around the signing date, the names of the witnesses, the drafting lawyer’s file, and the financial records that show who benefited.
Step three is the filing — “Petition to set aside probate of will” — a written petition filed in the existing probate proceedings in the district court where the will was admitted, stating the grounds (Iowa Code § 633.308). Before admission, the equivalent filing is “objections to probate of will” under Iowa Code § 633.310. Both are commonly called a will contest..

Step four is discovery and, in most cases, a settlement conference; the small minority that reach trial are decided by a jury if requested.
Settling Instead of Fighting
YES — Iowa permits negotiated resolution. Family settlement agreements among competent, fully informed interested persons are recognized and favored under Iowa common law, and a fiduciary may compromise contested matters affecting the estate with court approval under Iowa Code § 633.115 (compromise) and Iowa Code § 633.122 (settlement contested).
Court-ordered or voluntary mediation and other alternative dispute resolution is available in Iowa district court civil cases under Iowa Code chapter 679C and Iowa R. Civ. P. 1.601 et seq. A settlement that alters the distribution set by the will generally requires court approval, and approval is required where minors, unborn, or incapacitated beneficiaries have an interest.
Other Iowa rules: (1) NO ante-mortem / pre-death probate — Iowa Code chapter 633 creates no right for heirs or third parties to challenge or validate a will’s validity or the testator’s capacity while the testator is alive; the Iowa Supreme Court has held there is no remedy to set aside a will during the testator’s lifetime, so all contests are post-death.
(2) The limitations period is a two-pronged “later of” test (4 months from second publication OR 1 month from mailing to ascertainable heirs and devisees) — Iowa Code § 633.309 — which is short by national standards and is measured from notice, not death; missing it is generally fatal to the contest.
(3) A tortious-interference-with-inheritance claim premised on procurement of the will must be joined with a timely will contest and is subject to the same deadline — Iowa Code § 633.309(2). (4) Self-proved wills under Iowa Code § 633.279(2) are admitted without witness testimony and constitute proof of due execution under § 633.293, shifting the practical burden to the contestant.
(5) Will contests are law actions (Iowa Code §§ 633.33, 633.311), so either side may demand a jury — unlike most other probate matters, which are tried in equity. (6) Under Iowa Code § 633.279(1) two competent witnesses must sign in the testator’s presence; Iowa does not recognize holographic (unwitnessed handwritten) wills.
(7) A surviving spouse’s elective share (Iowa Code §§ 633.236–633.246) is a separate remedy with its own deadline and is not a will contest. (8) No-contest clauses now carry real force after Felten v. Hoffman (Iowa 2025), which placed the burden of proving both good faith and probable cause on the contestant.
The Evidence That Wins or Loses a Will Contest
Capacity cases turn on the weeks around the signing: the medical chart, prescriptions, a dementia diagnosis, and what the drafting lawyer and the witnesses saw that day. A will signed in a lawyer’s office with two disinterested witnesses and a self-proving affidavit is hard to attack; a will signed at a kitchen table with the main beneficiary present is not.
Undue influence cases turn on the relationship — who drove the parent to the appointment, who chose the lawyer, who was in the room, and whether the new will departed sharply from earlier ones and from what the parent said to other people.
Improper execution is the narrowest ground and the cleanest: Iowa sets exact witness and signature rules, and a will that misses them fails regardless of what the signer intended. Before you contest a will in Iowa, gather the prior wills, the medical releases, and the names of everyone at the signing.
Most of that evidence has to be requested formally once the case is filed, and the deadline does not wait for it.
What to Expect When You Contest a Will in Iowa
A will contest is a lawsuit about the document, not about fairness. When you contest a will in Iowa, the court asks whether the person who signed it had capacity, signed it freely, and signed it correctly. It does not ask whether the split was reasonable. That is why the strongest cases rest on medical records and witness accounts from the weeks around the signing.
Most families who contest a will in Iowa settle. Courts encourage it, many states have family settlement rules that let the heirs agree to a different division, and a settlement avoids the cost and delay of trial. The deadline, the grounds, and the no-contest clause above are the three facts that set your bargaining position before any of that begins.
