A user is seeking advice on how to legally change the caste listed as 'Hindu P.S.' on their father's 1972 school leaving certificate to 'Hindu Padmashaali'. School authorities are refusing the change, as 'P.S.' is not a recognised caste name. The user also has an aunt's certificate showing 'Hindu' and wishes to add 'Padmashaali'. They require this rectification for caste validity purposes, as the current entry is being questioned.
