Contact the Office of the Registrar at your college or university to determine specific application procedures. Most colleges have a form that must be completed and returned, usually by conventional mail.
Collect the required legal documentation to support your change of name. The Office of the Registrar will indicate what documents are considered appropriate: marriage and change-of-name certificates are typical, although some schools may required notarized affidavits as well.
Send the completed application for a replacement diploma with the required documentation and fee to the Office of the Registrar. If original documents are required, be sure to make copies of all materials and send them securely with a tracking number. Note the date that the documents were sent.
