Iowa Code Title XVI. Criminal Law and Procedure [Chs. 687-916] § 807.5. Bringing an indicted corporation into court

1. The clerk of the court wherein such indictment is found or the information filed, or the judge, must issue a summons signed by the clerk or judge with the clerk's or judge's name of office, requiring such corporation to appear and plead to the indictment, at a time and place to be specified in such summons, such time to be not less than twenty days after the issue thereof. The summons may be substantially in the following form:

2. The summons shall be served at least ten days before the appearance fixed therein, in the same manner as is provided for the service of an original notice upon a corporation in a civil action; and if the corporation does not appear or plead at the time and place specified in the summons, the court may proceed to trial and judgment without further process.

3. Nothing contained in this section shall be construed as preventing the appearance of a corporation by counsel to plead to an indictment, with or without the issuance or service of the summons provided herein. And when an indictment shall have been filed against a corporation it may voluntarily appear and plead to the same by counsel duly authorized to so appear for it.
