1. RBI circular on payment of cheque vide RBI/2011-12/288:

It is the usual practice   among the bankers to make payment of   only    such   cheques and drafts as are presented for payment within a period of 6 months from the date of instrument due to which some persons are taking undue advantage of circulating such instruments in the market like cash for 6 months. Hence, in public   interest  and  in  the  interest   of   banking   policy   RBI   has   reduced   the period  within which  cheques/drafts/payorders/bankers cheques are presented from 6 months to 3 months from the date of such instrument w.e.f 1.04.2012.
