VOTING BY MAILhttps://docs.legis.wisconsin.gov/statutes/statutes/6/iv/846.85  Absent elector; definition.
(1)  An absent elector is any otherwise qualified elector who for any reason is unable or unwilling to appear at the polling place in his or her ward or election district.
(2) Any otherwise qualified elector who changes residence within this state by moving to a different ward or municipality later than 28 days prior to an election may vote an absentee ballot in the ward or municipality where he or she was qualified to vote before moving.
(3) An elector qualifying under this section may vote by absentee ballot under ss. 6.86 to 6.89.
(4) (a) For the purpose of absentee voting in qualified retirement homes and residential care facilities, the municipal clerk or board of election commissioners of each municipality in which one or more qualified retirement homes or residential care facilities are located shall appoint at least 2 special voting deputies for the municipality. Except as provided in par. (am), upon application under s. 6.86 (1), (2), or (2m) by one or more qualified electors who are occupants of a home or facility, the municipal clerk or board of election commissioners of the municipality in which the home or facility is located shall dispatch 2 special voting deputies to visit the home or facility for the purpose of supervising absentee voting procedure by occupants of the home or facility. The clerk or board of election commissioners shall maintain a list, available to the public upon request, of each home or facility where special voting deputies are dispatched. The list shall include the date and time the deputies intend to visit each home or facility. The 2 deputies designated to visit each qualified retirement home and residential care facility shall be affiliated with different political parties whenever deputies representing different parties are available.
6.88  Voting and recording the absentee ballot.
(1)  When an absentee ballot arrives at the office of the municipal clerk, or at an alternate site under s. 6.855, if applicable, the clerk shall enclose it, unopened, in a carrier envelope which shall be securely sealed and endorsed with the name and official title of the clerk, and the words “This envelope contains the ballot of an absent elector and must be opened in the same room where votes are being cast at the polls during polling hours on election day or, in municipalities where absentee ballots are canvassed under s. 7.52, stats., at a meeting of the municipal board of absentee ballot canvassers under s. 7.52, stats." If the elector is a military elector, as defined in s. 6.34 (1), or an overseas elector, regardless of whether the elector qualifies as a resident of this state under s. 6.10, and the ballot was received by the elector by facsimile transmission or electronic mail and is accompanied by a separate certificate, the clerk shall enclose the ballot in a certificate envelope and securely append the completed certificate to the outside of the envelope before enclosing the ballot in the carrier envelope. The clerk shall keep the ballot in the clerk's office or at the alternate site, if applicable until delivered, as required in sub. (2).
(2) When an absentee ballot is received by the municipal clerk prior to the delivery of the official ballots to the election officials of the ward in which the elector resides or, where absentee ballots are canvassed under s. 7.52, to the municipal board of absentee ballot canvassers, the municipal clerk shall seal the ballot envelope in the carrier envelope as provided under sub. (1), and shall enclose the envelope in a package and deliver the package to the election inspectors of the proper ward or election district or, in municipalities where absentee ballots are canvassed under s. 7.52, to the municipal board of absentee ballot canvassers when it convenes under s. 7.52 (1). When the official ballots for the ward or election district have been delivered to the election inspectors before the receipt of an absentee ballot, the clerk shall immediately enclose the envelope containing the absentee ballot in a carrier envelope as provided under sub. (1) and deliver it in person to the proper election officials.
(3) (a) Except in municipalities where absentee ballots are canvassed under s. 7.52, at any time between the opening and closing of the polls on election day, the inspectors shall, in the same room where votes are being cast, in such a manner that members of the public can hear and see the procedures, open the carrier envelope only, and announce the name of the absent elector or the identification serial number of the absent elector if the elector has a confidential listing under s. 6.47
When the inspectors find that the certification has been properly executed, the applicant is a qualified elector of the ward or election district, and the applicant has not voted in the election, they shall enter an indication on the poll list next to the applicant's name indicating an absentee ballot is cast by the elector. They shall then open the envelope containing the ballot in a manner so as not to deface or destroy the certification thereon. The inspectors shall take out the ballot without unfolding it or permitting it to be unfolded or examined. Unless the ballot is cast under s. 6.95, the inspectors shall verify that the ballot has been endorsed by the issuing clerk. If the poll list indicates that proof of residence under s. 6.34 is required and proof of residence is enclosed, the inspectors shall enter both the type of identifying document submitted by the absent elector and the name of the entity or institution that issued the identifying document on the poll list in the space provided. If the poll list indicates that proof of residence under s. 6.34 is required and no proof of residence is enclosed or the name or address on the document that is provided is not the same as the name and address shown on the poll list, the inspectors shall proceed as provided under s. 6.97 (2). The inspectors shall then deposit the ballot into the proper ballot box and enter the absent elector's name or voting number after his or her name on the poll list in the same manner as if the elector had been present and voted in person.
(b) When the inspectors find that a certification is insufficient, that the applicant is not a qualified elector in the ward or election district, that the ballot envelope is open or has been opened and resealed, that the ballot envelope contains more than one ballot of any one kind or, except in municipalities where absentee ballots are canvassed under s. 7.52, that the certificate of a military or overseas elector who received an absentee ballot by facsimile transmission or electronic mail is missing, or if proof is submitted to the inspectors that an elector voting an absentee ballot has since died, the inspectors shall not count the ballot. The inspectors shall endorse every ballot not counted on the back, “rejected (giving the reason)". The inspectors shall reinsert each rejected ballot into the certificate envelope in which it was delivered and enclose the certificate envelopes and ballots, and securely seal the ballots and envelopes in an envelope marked for rejected absentee ballots. The inspectors shall endorse the envelope, “rejected ballots" with a statement of the ward or election district and date of the election, signed by the chief inspector and one of the inspectors representing each of the 2 major political parties and returned to the municipal clerk in the same manner as official ballots voted at the election.
(c) The inspectors shall review each certificate envelope to determine whether any absentee ballot is cast by an elector whose name appears on the poll list as ineligible to vote at the election by reason of a felony conviction. If the inspectors receive an absentee ballot that has been cast by an elector whose name appears on the poll list as ineligible for that reason, the inspectors shall challenge the ballot as provided in s. 6.92 and treat the ballot in the manner provided in s. 6.95.
