Im getting married in Vegas but live in Michigan

No. You need a marriage license from the place where you're getting married.

I think in the U.S. you marry anywhere and it counts. Canada is the same way, if I got married in Alberta I would still be married in B.C. I think you just register when you get back to Michigan with your Arizona marriage license. (there is probably a lot of paper work or something involved)

Only in the state you get married. Vegas courthouse is downtown, $60, bring cash or there is an extra fee. you can do the pre application online to make it even easier. last i looked its good for 365 days from date of issue.

You would get your license from the county Vegas is in, luckily in Vegas there is no waiting period and can get your license anytime day or night!

Actually the hours are 8 AM- Midnight but thats still 7 days a week including holidays.

we had to cut out overnight hours to avoid the drunk dumbass mistake weddings.
