Iowa Motion to Dismiss
In Iowa you move to dismiss a petition under Iowa R. Civ. P. 1.421(1) within the 20-day answer window.
Introduction
In Iowa you challenge a petition before answering by filing a motion to dismiss as a pre-answer motion under Iowa R. Civ. P. 1.421(1), most often Iowa R. Civ. P. 1.421(1)(f) for failure to state a claim upon which any relief may be granted. Iowa uses its own rule numbering rather than the federal Rule 12(b) scheme, and Rule 1.421(1) lists six lettered matters that may be raised by pre-answer motion: (a) lack of subject-matter jurisdiction, (b) lack of personal jurisdiction, (c) insufficiency of the original notice or its service, (d) to recast or strike, (e) for a more specific statement, and (f) failure to state a claim. Improper venue is raised separately under Rule 1.421(2). The motion shares the answer window: under Iowa R. Civ. P. 1.303(1) you serve a motion or answer within 20 days after service of the original notice and petition, so a pre-answer motion stands in lieu of the answer in that window. A failure-to-state-a-claim motion is decided on the face of the petition; Rule 1.421(6) requires the motion to specify how the pleading is claimed to be insufficient. A supporting brief is optional under Rule 1.431(3), not required. Missing the 20-day window without filing a motion or answer risks a default under Rule 1.971(1).

Rule 1.421(1) lists six lettered matters that 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 a more specific statement, and (f) failure to state a claim upon which any relief may be granted.

The pre-answer motion shares the answer window: under Iowa R. Civ. P. 1.303(1) you serve a motion or answer within 20 days after service of the original notice and petition. The rule lists a motion or answer as alternatives in the same window, so filing a pre-answer 1.421 motion stands in lieu of the answer; failing to file either by day 20 is a default under Rule 1.971(1).

Rule 1.421(3) forces consolidation: grounds (b) through (f) that exist at the time must be raised in a single pre-answer motion, so you generally get one pre-answer motion per pleading. Under Rule 1.421(4), failing to raise a matter waives it, except lack of subject-matter jurisdiction and failure to state a claim, which are not waived by omission.

A supporting brief is optional, not required: Rule 1.431(3) provides that a concise memorandum brief citing supporting authorities may be served. What is mandatory is form: Rule 1.431(2) requires each motion to be captioned and signed under Rule 1.411 and to set out the specific points on which it is based, and Rule 1.421(6) requires the motion to specify how the attacked pleading is claimed to be insufficient. Individual judicial-district or local rules may add conference or briefing requirements, so re-confirm the local rule of the filing court.

The most common ground is Iowa R. Civ. P. 1.421(1)(f), failure to state a claim upon which any relief may be granted. It is decided on the face of the petition: the test looks to whether the petition on its face shows the pleader is entitled to no relief, and Rule 1.421(6) requires the motion to specify how the petition is insufficient.

File in the Iowa District Court, the court of general civil jurisdiction, with the clerk of the district court in the county where the action is pending. The opposing party has 10 days to file a written resistance under Rule 1.431(4), and the movant may file a reply within 7 days after service of the resistance or before any hearing, whichever is earlier, under Rule 1.431(5).
