If you need to change your father's name on a Class 8 Transfer Certificate (TC), the school generally cannot do this directly. The process depends on whether the name is incorrect due to a school error or if your father is legally changing his name. If the school recorded the name incorrectly compared to your birth certificate or admission records, they should rectify it. For a legal name change, your father must follow the official procedure with the Tahsildar, potentially requiring an affidavit.
