The State of New Jersey Department of Health web site outlines how to apply for a marriage license. From this site you can download the license application form.
This is a quick summary of what you need to do (I go over it in detail when we meet).
As long as one of you is a resident in the State of New Jersey, your marriage license must be obtained from the registrar in the municipality in which you reside. A license issued in this manner is valid for 30 days and good for use anywhere in the State of New Jersey.
If both of you are not residents of New Jersey, the license may only be obtained from the clerk of the municipality where the ceremony is to be performed. It’s valid for 30 days but is only good for use in that municipality.

A marriage ceremony can be performed by any federal, state, municipal judge or magistrate (even if they are retired); any county clerk; any mayor or deputy mayor of a town; chairman of any township committee; and every minister/reverend of every religion, including Internet ministries.
You can submit the marriage license application up to six months prior to your wedding date, although most couples usually go a few weeks before the actual date. The clerk can’t issue a marriage license sooner than 72 hours after the application has been submitted (see example below). Once the license is issued, it is good for 30 days from the date of issuance.
The marriage license application must be completed by both of you and your witness before the license is issued.
Example: If your ceremony is scheduled for a Saturday or Sunday, the latest the application can be submitted is the preceding Tuesday in order to have your license back by Friday. However, waiting until this late is not recommended unless there is no other option. (Clerks are generally not available on Saturday, Sunday or any public holiday.)
Each applicant is required to provide the following, as applicable:
We’ll set a date/time and place to meet that is mutually convenient. If you live outside New Jersey and won’t be here soon, we can set up our initial meeting via Skype or Facetime.
Before we meet, I’ll email you sample ceremonies to review along with some information about the NJ marriage license process.
At our meeting we’ll discuss the details about your bridal party, what type of ceremony you have in mind and whether or not you’ll want any rituals or traditions included, or if you’ll want friends or family members to participate (e.g., readings, unity candle/sand ceremony). We’ll also review in detail the process for obtaining your NJ marriage license.
I’ll leave two copies of my contract with you, pre-signed by me, and ask that you take some time to consider what we’ve discussed and determine if I am the “right” officiant to join you in marriage.
I’m always deeply honored when asked to take on the responsibility of performing a wedding ceremony.
Return one signed contract to me with your retainer check. (The balance is due on or before the day of your ceremony.) We’ll work together via email to develop your ceremony, until we get it exactly the way you envision it.
