A marriage or civil union license obtained in New Jersey may never be used outside of the state, and a license issued in another state may never be used within the state. Contact the Registrar well in advance of the ceremony to discover out what days and hours the Registrar will be at the office. You should also contact the local county clerk's office for an exact location. In general, you cannot use a New Jersey marriage license in any other state except New Jersey. However, if you are married by an authorized representative of the State of New Jersey who is licensed to perform marriages, then your marriage is considered valid in other states. The only way to verify this information is to contact the office that issued the license. New Jersey has five months from the date of issuance to return a license. If it is not done so within this time frame, then the license becomes invalid. A new license must be received by the registrar within three days of the old one being returned as undeliverable. If this deadline is missed, an additional charge will be required to reissue the license. The cost of a marriage license is $60. This fee includes the cost of processing the application, checking validity requirements, and printing the license. There is no charge for reissuing a license that was lost or damaged in the mail. Marriage licenses can be obtained in most counties in New Jersey.
