Thank you so much for responding so quickly to my post. I want to make sure I understand correctly. My son and his fiance should use their legal names on the marriage license and then both of them petition for the new last name. That is both of them do separate paperwork for the new last name. Is it possible for the name change for two people to be on one form and only pay one fee? So the new bride should hold off on going to the Social Security office and other places to do paperwork of new name until they have gone through the court process. Once their names are changed what about the marriage certificate? Do they have to do new paperwork? She should continue to use her legal name until name change paperwork is finished. Thank you for your help.
