We recently got married, and I want to change my last name to my husband's. I called City Hall in Philadephia where we got our marriage license, and they said there's no official government name changing form, but that I have to change it at each individual place (Social Security, DMV, etc.). Does anyone know for sure if this is true? I assumed I would have to file for an official name change at City Hall or with the PA government before I could change it everywhere else.
