Marriage License Requirements

Usually you need 2 forms of ID (see link above), Divorce decree / proof of termination of any previous marriages (original with raised seal)

The license is good for 60 days, but don't wait until the day before because there is a 24 hours waiting period before the license can be executed.

New York City (City of New York Clerk's Website) I would suggest you check out the websites or call to ensure you have everything you need.
