In case you shift outside of your current constituency

If you are shifting your permanent residence to a place outside your constituency, you must have your name deleted from the present electoral roll or have someone file an application to remove your name for you. Once you have done this, you must re-register yourself as a new voter and check the box in Form 6 next to ‘due to shifting from another constituency’ and submit it to the Electoral Registration Officer.
