Mental Competency & Voting Rights

Only a Superior Court can declare a person unable to vote due to mental incompetency and therefore unable to vote. Do not assume that a person under a guardianship due to their mental capacity is ineligible to vote.

A guardian may not vote on behalf of a person under guardianship, and power of attorney does not extend to voting.

Whether a person under guardianship may vote depends on when the guardianship was imposed and whether the guardianship is full or partial.

  • If full guardianship was imposed before July 24, 2005, the person is not eligible to vote unless the court order specifically states otherwise.
  • If partial guardianship was imposed before July 24, 2005, the person retains the right to vote unless the court order specifically states otherwise.
  • If full or partial guardianship was imposed on or after July 24, 2005, the person retains the right to vote unless the court order specifically states otherwise.
