Iowa Code § 53.31

(1) Any person qualified to vote at the election in progress may challenge the qualifications of a person casting an absentee ballot by submitting a written challenge to the commissioner no later than 5:00 p.m. on the Friday before the election. It is the duty of the special precinct officials to challenge the absentee ballot of any person whom the official knows or suspects is not duly qualified. Challenges by members of the special precinct election board or observers present pursuant to section 53.23 may be made at any time before the close of the polls on election day. The challenge shall state the reasons for which the challenge is being submitted and shall be signed by the challenger. When a challenge is received the absentee ballot shall be set aside for consideration by the special precinct election board when it meets as required by section 50.22.

(2) The commissioner shall immediately send a written notice to the elector whose qualifications have been challenged. The notice shall be sent to the address at which the challenged elector is registered to vote. If the ballot was mailed to the challenged elector, the notice shall also be sent to the address to which the ballot was mailed if it is different from the elector’s registration address. The notice shall advise the elector of the reason for the challenge, the date and time that the special precinct election board will reconvene to determine challenges, and that the elector has the right to submit written evidence of the elector’s qualifications. The notice shall include the telephone number of the commissioner’s office. If the commissioner has access to a facsimile machine, the notice shall include the telephone number of the facsimile machine. As far as possible, other procedures for considering provisional ballots shall be followed.
