My fiance and I want to have a legal ceremony here in canada to avoid the costs of getting all of his divorce documents translated into spanish and we are going to "renew our vows" in Cuba. None of our guests will know that it is not the real ceremony and we are going to ask for some papers for us to sign as well. My only concern is what paperwork do we have to bring with us in order to renew our vows? Birth Certificate and Passports and a copy of our marriage licence from Canada? I couldn't seem to find this information.
