Let's get hitched in Vegas!
It should be an easy proposition. It is actually. compared to other places. As long as:
A. You are both free to legally marry each other.
B. Well that's it really.
To get married in Las Vegas, much like in any other place, you will need to obtain a marriage license. Here, you can get that license 365 days of the year. The Regional Justice Center has the Marriage Licence Bureau that is open from 8am to 12 midnight every day of the week. Sometimes they open for 24 hours, but those are for special days.
The address to the Clark County Marriage License Bureau is
301 Clark Street, Las Vegas, NV
Both parties will need government issued identification. Driver's license for US residents and Passports for foreign applicants are accepted.
You will need the marriage license in order to have the marriage performed. After the ceremony, the marriage license will be submitted to the Clark County Recorder's office and then it will be official. Your actually marriage certificate will then be issued soon after.
