Very quick & easy! Makes getting married simple.
I recommend filing out the online application that just consists of your name, social security number, along with your soon-to-be-spouses & parent information. Make sure to save confirmation number after you've finished the application.
Bring that with you once you go to the marriage bureau and a valid ID or drivers license. Literally from there it takes all of 5 minutes once you've been called to the window.
After that make sure to keep all paper work, I mean you're going to need that to marry! But it was quicker than I thought and now tomorrow is my wedding day. Good luck to all couples considering getting their license!
