How to Change Your Party Affiliation in NJ

  • You do not have to affiliate with a party when registering to vote. If you do not choose a party, you will be classified as “UNAFFILIATED”.

  • In order to vote in a Primary Election, you must declare the party you wish to vote in. If you are “UNAFFILIATED”, you may declare your party either by filling out a State of New Jersey Political Party Declaration Form and submitting it to the Somerset County Board of Elections 55 days prior to the election or simply by declaring your party at the polls on the day of the election.
  • If you have declared a party and wish to change that affiliation, you must submit a State of New Jersey Political Party Declaration Form 55 days prior to the Primary Election.


Union County

A registered voter currently affiliated with a political party who wishes to change their party affiliation must file a Political Party Affiliation Declaration Form 55 days before a Primary Election. A registered voter currently not affiliated with a political party may declare their party affiliation up to and including Primary Election day. You can print and complete the Political Party Affiliation Declaration Form and mail or deliver to the Commissioner of Registration in your county or you can also file it with your municipal clerk. These cards are also available at your local Commissioner of Registration Office. The Commissioner of Registration cannot accept faxed copies or an electronic transmission of Party Affiliation Declaration Forms, since an original signature is required.
