hola!
That is super common here in los cabos, mostly if the couples just do a vows wedding, having a religious wedding can be stressful for most brides as many paper are involved! Legal ceremonies are really easy, you just need to secure your date and bring basic legal papers such as Passport, Birth certificate and if Divorce that paper too, copies of your immigration cards (you’ll get them at the airport ) and fill up the marriage papers.
But if you are thinking on having a religious wedding, then you need to talk with Padre Juvencio, he is the only priest that speaks English in San Jose Curch,
Good Luck
