Iowa Code § 62.15: Amendment — continuance.

If any part of the causes are held insufficient, they may be amended, but the incumbent will be entitled to an adjournment, if the incumbent states on oath that the incumbent has matter of answer to the amended causes, for the preparation of which the incumbent needs further time. Such adjournment shall be upon such terms as the court thinks reasonable; but if all the causes are held insufficient and an amendment is asked, the adjournment shall be at the cost of contestant. If no amendment is asked for or made, or in case of entire failure to prosecute, the proceedings may be dismissed.
