In order to get married in Las Vegas, you must get a Marriage License. Just like a Driver’s License is for Driving, a Marriage License says you and your partner qualify to be married. Getting a marriage license in Las Vegas is easy and economical (that’s why it’s the Marriage Capital of the World). You will have to fill out an application either in-person or online. You will need to know your parents’ names and birthplace (city and state, or country if international), and the date of the most recent divorce (if either of you are divorced) or the date of you last spouse’s death if widowed.
