No Friend . After ur completion of articleship, u r not required to sign in ur form by ur Principal But, it should be signed by any other CA.

No attestation of your old principal is required. Any CA signature will do.

Any CA can attest it now......... No attestion of ur old CA is required................

is there a time period for pcc registration after which you have to again register yourself with the board.

@ amitabh no time limit. valid for life long.

Thank You for all your help, much appreciated : ]
