During counselling conducted by DOTE Tamil Nadu, candidates must upload and later produce original documents for verification. These typically include TANCET scorecard, 10th and 12th mark sheets, degree mark sheets and provisional/degree certificate, transfer certificate, community certificate (if applicable), nativity certificate (if claiming Tamil Nadu domicile), income certificate (if applicable), and other relevant certificates such as differently-abled or ex-servicemen certificates if claiming special reservation. Failure to provide valid documents may lead to cancellation of candidature.
