How To Vote
You can vote by post, or in person in
advance of election day, if you expect to be out of the island or
otherwise committed on polling day, or if you have a physical illness or
disability that prevents you from attending.
If any of these circumstances affect you, and you want to apply to vote
by post or in person in advance, you need to complete the applicable
application form and return it to the Judicial Greffe.
If you have applied for a postal vote the Judicial Greffe will send you
a ballot paper, which you must complete and return, either in person or
by post by the relevant deadline. A Pre-Poll elector will have to attend
at the office of the Judicial Greffe. Application forms to register as a
Postal or Pre-Poll Voter will be available for each election from the
Parish website, the Judicial Greffe website, and nearer to the time from
the Jersey Library and the States Bookshop.
If you apply to vote in this way you are disqualified from voting in
person on Election Day.
