I want to change my father's name in icar application form
The application process for ICAR has already finished on 31 March, 2020. And the correction window will open from 25 April, 2020 to 2 May, 2020. You can change your father's name and correct it then, as correclty in that detail is allowed. Remind you, not all details can be corrected once filled. Only Some , such as Candidate name, mother's name, father's name, DOB, gender, photograph uploaded etc.,can be corrected.
Hope this helps.
Good luck!
