If your father's name appears differently across your documents (e.g., 'nasirbhai' on yours vs. 'abdul nasir' on his), it's important to address this. You can resolve the issue by obtaining notarised affidavits from both yourself and your father confirming the correct name. If further action is needed, your father can apply for a Gazette Notification through the Tahsildar. It's best to reconcile and amend your documents to match your father's officially documented name to avoid future complications.
