Generally, you may become a registered voter in Florida if you 1) are at least 18 years old, 2) are a citizen of the United States, 3) are a legal resident of Florida, 4) are a legal resident of the county in which you seek to register, and 5) you register pursuant to the Florida Election Code, so long as you have not been adjudicated mentally incapacitated with respect to voting nor have not been convicted of certain violent felonies without having voting rights restored by the Governor and Cabinet vote to restore their voting rights on a case by case basis. In November 2018, Florida voters approved Amendment 4 that automatically restores the voting rights of Floridians with felony convictions after they complete all terms of their sentence including parole or probation. The amendment does not apply to those convicted of murder or sexual offenses. You may preregister on or after your 16th birthday and may vote in any election occurring on or after your 18th birthday.
In order to register to vote, you must take an oath to defend the United States Constitution and the Constitution of the State of Florida and fill out a uniform statewide voter registration application. A person who willfully swears or affirms falsely to any oath in connection with voting or who willfully submits any false voter registration information commits a felony of the third degree.
