Applicants must describe custodial services, physical infrastructure including vaults or warehouses, organisation and key personnel, safekeeping and security systems, and IT systems for record keeping, backup and disaster recovery. The application must be signed, fee paid, copies self attested, and include a declaration to comply with SEBI Act, the Regulations and Board directives.
