Legal Question in Family Law in Florida

not sure of all of them, but Florida does not.

I don't know of any state that has a background check requirement, but almost all states have a waiting period before you can get married in that state, including Florida (the other lawyer who answered your question is mistaken). Florida, however, waives its waiting period if you take a premarital class. I'm not sure of its accuracy, but I found this website which lists each state's waiting periods: http://www.usmarriagelaws.com/search/united_states/florida/marriage_licenses/
