(10 ILCS 5/18A-5)
    Sec. 18A-5. Provisional voting; general provisions.
    (a) A person who claims to be a registered voter is entitled to cast a provisional ballot under the following circumstances:
        (1) The person's name does not appear on the official
    
list of eligible voters for the precinct in which the person seeks to vote. The official list is the centralized statewide voter registration list established and maintained in accordance with Section 1A-25;
        (2) The person's voting status has been challenged by
    
an election judge, a pollwatcher, or any legal voter and that challenge has been sustained by a majority of the election judges;
        (3) A federal or State court order extends the time
    
for closing the polls beyond the time period established by State law and the person votes during the extended time period; or
        (4) The voter registered to vote by mail and is
    
required by law to present identification when voting either in person or by absentee ballot, but fails to do so.
    (b) The procedure for obtaining and casting a provisional ballot at the polling place shall be as follows:
        (1) After first verifying through an examination of
    
the precinct register that the person's address is within the precinct boundaries, an election judge at the polling place shall notify a person who is entitled to cast a provisional ballot pursuant to subsection (a) that he or she may cast a provisional ballot in that election. An election judge must accept any information provided by a person who casts a provisional ballot that the person believes supports his or her claim that he or she is a duly registered voter and qualified to vote in the election. However, if the person's residence address is outside the precinct boundaries, the election judge shall inform the person of that fact, give the person the appropriate telephone number of the election authority in order to locate the polling place assigned to serve that address, and instruct the person to go to the proper polling place to vote.
        (2) The person shall execute a written form provided
    
by the election judge that shall state or contain all of the following that is available:
        (i) an affidavit stating the following:
            State of Illinois, County of ................,
        
Township ............., Precinct ........, Ward ........, I, ......................., do solemnly swear (or affirm) that: I am a citizen of the United States; I am 18 years of age or older; I have resided in this State and in this precinct for 30 days preceding this election; I have not voted in this election; I am a duly registered voter in every respect; and I am eligible to vote in this election. Signature ...... Printed Name of Voter ....... Printed Residence Address of Voter ...... City ...... State .... Zip Code ..... Telephone Number ...... Date of Birth ....... and Illinois Driver's License Number ....... or Last 4 digits of Social Security Number ...... or State Identification Card Number issued to you by the Illinois Secretary of State........
        (ii) A box for the election judge to check one of the
    
3 reasons why the person was given a provisional ballot under subsection (a) of Section 18A-5.
        (iii) An area for the election judge to affix his or
    
her signature and to set forth any facts that support or oppose the allegation that the person is not qualified to vote in the precinct in which the person is seeking to vote.
    The written affidavit form described in this subsection (b)(2) must be printed on a multi-part form prescribed by the county clerk or board of election commissioners, as the case may be.
    (3) After the person executes the portion of the written affidavit described in subsection (b)(2)(i) of this Section, the election judge shall complete the portion of the written affidavit described in subsection (b)(2)(iii) and (b)(2)(iv).
    (4) The election judge shall give a copy of the completed written affidavit to the person. The election judge shall place the original written affidavit in a self-adhesive clear plastic packing list envelope that must be attached to a separate envelope marked as a "provisional ballot envelope". The election judge shall also place any information provided by the person who casts a provisional ballot in the clear plastic packing list envelope. Each county clerk or board of election commissioners, as the case may be, must design, obtain or procure self-adhesive clear plastic packing list envelopes and provisional ballot envelopes that are suitable for implementing this subsection (b)(4) of this Section.
    (5) The election judge shall provide the person with a provisional ballot, written instructions for casting a provisional ballot, and the provisional ballot envelope with the clear plastic packing list envelope affixed to it, which contains the person's original written affidavit and, if any, information provided by the provisional voter to support his or her claim that he or she is a duly registered voter. An election judge must also give the person written information that states that any person who casts a provisional ballot shall be able to ascertain, pursuant to guidelines established by the State Board of Elections, whether the provisional vote was counted in the official canvass of votes for that election and, if the provisional vote was not counted, the reason that the vote was not counted.
    (6) After the person has completed marking his or her provisional ballot, he or she shall place the marked ballot inside of the provisional ballot envelope, close and seal the envelope, and return the envelope to an election judge, who shall then deposit the sealed provisional ballot envelope into a securable container separately identified and utilized for containing sealed provisional ballot envelopes. Ballots that are provisional because they are cast after 7:00 p.m. by court order shall be kept separate from other provisional ballots. Upon the closing of the polls, the securable container shall be sealed with filament tape provided for that purpose, which shall be wrapped around the box lengthwise and crosswise, at least twice each way, and each of the election judges shall sign the seal.
    (c) Instead of the affidavit form described in subsection (b), the county clerk or board of election commissioners, as the case may be, may design and use a multi-part affidavit form that is imprinted upon or attached to the provisional ballot envelope described in subsection (b). If a county clerk or board of election commissioners elects to design and use its own multi-part affidavit form, then the county clerk or board of election commissioners shall establish a mechanism for accepting any information the provisional voter has supplied to the election judge to support his or her claim that he or she is a duly registered voter. In all other respects, a county clerk or board of election commissioners shall establish procedures consistent with subsection (b).
    (d) The county clerk or board of election commissioners, as the case may be, shall use the completed affidavit form described in subsection (b) to update the person's voter registration information in the State voter registration database and voter registration database of the county clerk or board of election commissioners, as the case may be. If a person is later determined not to be a registered voter based on Section 18A-15 of this Code, then the affidavit shall be processed by the county clerk or board of election commissioners, as the case may be, as a voter registration application.
