The Indemnity Bond and Affidavit should be signed by the shareholder and jointholders if any and their signatures SHOULD tally with the one in the Application / Transfer Deed.

When to rematerialise?
Security settlement in Indian securities markets takes place only in the demat form and hence, it is advisable to hold shares in the demat form only to quickly sell shares as and when desired. An investor can rematerialise shares only when he has no intention to sell his holdings and wants to hold shares only for the purpose of investment for the long term.
