My son name in school school certificate is with family name while in Adhar it is without family name. Will it be accepted for JEE applicati

According, to JEE Main if name  of  the  candidate  in  Aadhaar  in  not exactly  similar  or  not  in  same  pattern  as  in school records such   candidates   should   submit   a   correction   request   at Aadhaar  centre  and  apply  for  JEE  (Main)  by  entering 14 digits Aadhaar Enrolment ID/UR No. (Including slash)printed on   the slip   issued   by   aadhaar   centre   after   submitting updation request.

Or

Such  candidates  should  fill  the  form  of  JEE  (Main)  with  old details  in  Aadhaar  card  and  thereafter  submit  a  correction request  at  Aadhaar  centre.  The  updated  details  in  Aadhaar may be corrected in JEE (Main) at later stage by the process which will be notified in due course of time.

Good Luck!!
