So we are in the process of changing my fionces last name, he was supposed to do this a lot earlier but forgot or procrastinated or something and now were 23 days from getting married and we want him to have his new name on the marrige so it won't cost us an arm and a leg to change mine after we get married. It takes three days for the marrige license to be valid and I'm not sure how long it will take for his name to be legally changed. Could we do a ceremony for show and then get the lisence and sign the paper work after his name is legal if its going to take too long?
