I'm also getting married at the Riu Palace, June 24th, 2011. Yes, it's quite confusing trying to understand what the requirements are. It was even more complicated for us, because this is our 2nd wedding. We also had to provide certified & translated copies of our divorce papers! This is what I have learned and done, hopefully this is correct and will be acceptable when we arrive there in two weeks! -Original certified copy of birth certificate for each of you. Translated, notarized (or authenticated) and apositilled.(they will all be stapled together) -Passports (not translated) -Tourist Card-you will receive this when you enter Mexico -Marriage application (they will email this to you) I uploaded my documents to an online translation service (Fox Translation). They have a 24 hour turn around. I'm from the Los Angeles area, and I found out (later, than sooner) there are a lot of mobile services that will take care of all the running around for you, and can get the documents "authenticated" and "appositilled", depending on where you live, I'm sure. Where are you from? Hope some of this helps. Congrats to you!!
