My question has two parts regarding with the -
- Regulation of First and/or Middle name
- Regulation of Last name
First question might not be tricky but for second question there could be some challenges.
As we know most of the last names in India are either
- caste (like Sharma, Sahu, Rao) or
- generic terms (like Kumar, Singh) or
- some family name (like Allu — mainly in South India)
In this regard except for caste based last name there shouldn't be any problem.
Now for caste based last names —
What if someone belonging to Sharma caste names their child ABC Sahu ?
Is it allowed?
If allowed - What about reservation for which Govt manages list of castes under various categories like Gen/OBC/SC/ST ?
(However there must be other evidences to decide category - still there could be problems like Meena and Mina where only Minas are given reservation benefits and spelling change can erupt confusions as it already did. — Latin and Devanagari scripts being used in Certificates)
