Hello,

not exactly cast but if you are claiming reservation, i.e., if you want to take reservation if you are SC/ST or OBC ( as only few college have OBC reseration) then you need to upload the category you fall in or under which youare claiming reservation.

here is a link that will provide you with all details on the documents that you will be required to attaach while you will fill the application form

Further, CLAT 2019 form is not available and is available till March 31, 2019. Exam will be conducted on May 12, 2019 and application fee is 4000 for Gen and OBC and 3500 for SC/ST. 

Hi !

It depends , if you are from the General category ,it's not at all required.

But if you fall in some other category & you want to take the reservation then you will have to upload the caste certificate as a proof. 

The other documents required are,

• Birth Certificate or Passport
• High School mark sheet 
• 10+2  qualifying examination mark sheet
• colored passpost sized photograph
• Candidate's signature
• Disability certificate for differently abled candidates
• Domicile certificate

Hope it helps!
