Indiana Code Title 3. Elections § 3-11-14-24

Sec. 24. (a) Only one (1) voter may occupy a booth or compartment at one time.  Booths shall be constructed and arranged so that all members of the precinct election board can see whether more than one (1) voter enters a booth at any one time.  However, a voter who is a parent, grandparent, or other person caring for a minor child may take the child into the voting booth.

(b) If a voter needs additional instruction after entering the voting booth, the voter may request assistance from the two (2) judges.  The two (2) judges shall then approach but not enter the booth and call out additional instructions to the voter.
