"Qualified voter" means a person who:

• Is 18 years of age or older;
• Is a United States citizen;
• Has not been determined by a final judgment of a court exercising probate jurisdiction to be totally mentally incapacitated or partially mentally incapacitated without the right to vote;

In the Election Code, "residence" means domicile, that is, one's home and fixed place of habitation to which one intends to return after any temporary absence. A person may not establish residence for the purpose of influencing the outcome of a certain election. A person does not lose the person's residence by leaving to go to another place for temporary purposes only. A person does not acquire a residence in a place to which the person has come for temporary purposes only and without the intention of making that place the person's home. A person may not establish a residence at any place the person has not inhabited. A person may not designate a previous residence as a home and fixed place of habitation unless the person inhabits the place at the time of designation and intends to remain.

Election Code 1.015

For purposes of satisfying the continuous residency requirement, a person who claims an intent to return to a residence after a temporary absence may establish that intent only in accordance with Election Code 141.001(a-1), which does not apply to a person displaced from the person's residence due to a declared local, state, or national disaster.
