You may only vote by mail in Texas if any of the following conditions apply to you:
An application for a ballot by mail is available online at https://www.sos.texas.gov/elections/voter/reqabbm.shtml. Print and complete the form, then mail it to the early voting clerk in your county.
Some county early voting clerks offer the option to submit early voting applications by email. Because Mansfield is located in three counties, Mansfield residents should contact their county's election office for more information.
