I don’t understand all this fuss about consulting a lawyer and stuff.
Find a judge, get two friends to be witnesses. Go to the courthouse over lunch, have everyone sign the form, and then treat your friends to a decent lunch (<$35).
It’s really not that big of a deal, as long as it hasn’t been a long time since your wedding. Most officiants prefer to get the legal stuff done right after/before the ceremony so you won’t have to meet up with them again. Other than that, you got married on the day you think you got married. Nobody’s going to care that your license is a few days off.
Unless, of course, it’s been more than a few days, but even then, you have no other recourse than to just get it done ASAP so a few weeks doesn’t turn into a few months (which could raise eyebrows later).
