The Iowa pre-answer motion: you get one, and it must say how the pleading fails
Iowa procedure · Last verified August 17, 2026
Iowa gives a defendant a single shot. Rule 1.421(3) requires grounds (b) through (f) to be contained in a single motion, and permits only one such motion assailing the same pleading.
Rule 1.421(4) then waives whatever you left out, with two exceptions.
And Rule 1.421(6) adds a content requirement most states leave to practice: the motion must specify how the pleading is insufficient.
The six grounds
Iowa R. Civ. P. 1.421(1):
Every defense to a claim for relief in any pleading must be asserted in the pleading responsive thereto, or in an amendment to the answer made within 20 days after service of the answer, or if no responsive pleading is required, then at trial. The following defenses or matters may be raised by pre-answer motion: a. Lack of jurisdiction of the subject matter. b. Lack of jurisdiction over the person. c. Insufficiency of the original notice or its service. d. To recast or strike. e. For more specific statement. f. Failure to state a claim upon which any relief may be granted.
| Ground | |
|---|---|
| a. lack of subject matter jurisdiction | |
| b. lack of personal jurisdiction | |
| c. insufficiency of the original notice or its service | Iowa's term for process |
| d. to recast or strike | folded into the same rule |
| e. for more specific statement | folded in as well |
| f. failure to state a claim upon which any relief may be granted |
Two of these sit elsewhere in most states. A motion to recast or strike and a motion for more specific statement are separate rules under the federal scheme; Iowa treats them as grounds of the same pre-answer motion — which matters because of the one-motion rule below.
The opening sentence also carries a deadline worth knowing: a defense not raised by motion must be in the responsive pleading, or in an amendment to the answer made within 20 days after service of the answer. That 20-day window is a real second chance, and it is easy to miss.
Venue has its own sentence
Rule 1.421(2):
Improper venue under rule 1.808 must be raised by pre-answer motion filed prior to or in a single motion under rule 1.421 (3).
Venue is motion-only. It cannot be preserved in the answer, and it must come either before or inside the single consolidated motion.
One motion, and one only
Rule 1.421(3):
If the grounds therefor exist at the time a pre-answer motion is made, motions under rule 1.421 (1)(b) through 1.421 (1)(f) shall be contained in a single motion and only one such motion assailing the same pleading shall be permitted, unless the pleading is amended thereafter.
Two commands. Grounds (b) through (f) shall be contained in a single motion. And only one such motion attacking the same pleading is permitted — unless the pleading is later amended, which reopens the door.
Subject matter jurisdiction, ground (a), sits outside that range and is not subject to the consolidation requirement.
What you lose by leaving something out
Rule 1.421(4):
If a pre-answer motion does not contain any matter specified in rule 1.421 (1) or 1.421 (2) that matter shall be deemed waived, except lack of jurisdiction of the subject matter or failure to state a claim upon which relief may be granted.
| Matter | Survives omission? |
|---|---|
| Lack of subject matter jurisdiction | yes |
| Failure to state a claim | yes |
| Personal jurisdiction | no — waived |
| Insufficiency of the original notice or its service | no — waived |
| To recast or strike | no — waived |
| For more specific statement | no — waived |
| Improper venue | no — waived |
Everything but the two named exceptions is gone. Because the rule folds recast, strike and more-specific-statement into the same list, a defendant who moves only to dismiss and later wants a more specific statement has lost it.
The motion must explain itself
Rule 1.421(6):
Motions under this rule must specify how the pleading they attack is claimed to be insufficient.
A one-line motion asserting that the petition fails to state a claim does not comply. Say how.
Rule 1.421(5) adds the mirror for the other side: "Sufficiency of any defense may be raised by a motion to strike it, filed before pleading to it."
Before you file
- Inventory every available ground first. You get one motion.
- Include venue if it applies — it cannot be saved for the answer.
- Specify how the pleading is insufficient, item by item.
- Consider whether you also want a recast, a strike, or a more specific statement. They belong in the same motion.
- If you answer instead, diary 20 days — that is the window to amend the answer to add defenses.
If a default has already been entered, Iowa's set-aside window is the shortest in the country at 60 days — see setting aside an Iowa default judgment.
How Iowa compares
| Iowa | Nebraska | Minnesota | Federal | |
|---|---|---|---|---|
| Only one pre-answer motion permitted | yes | no | no | no |
| Motion must specify how the pleading fails | yes | no | no | no |
| Recast, strike and more-definite-statement folded in | yes | no | no | no |
| Venue motion-only | yes | — | — | no |
| Window to amend the answer to add defenses | 20 days | — | — | as of course |
| Grounds surviving omission | two | — | — | three |
A short checklist
- Build one motion containing every ground (b) through (f).
- Add venue under 1.421(2) if it applies.
- Explain how the pleading is insufficient — the rule requires it.
- Do not plan a second motion. Only one is permitted unless the pleading is amended.
- Remember what survives — subject matter jurisdiction and failure to state a claim.
- If you answered, use the 20-day amendment window to add anything missing.
- To attack a defense, move to strike before pleading to it.
