i am not too sure, but a dishonoured cheque under section 138 is a criminal offence. you can approach the court for reprive. the court shall issue notices and if the person fails to appear, then issue Non-Bailable Warrant.
it is not a matter of the amount or the purpose for which a cheque is issued, but that cheque has to be honoured.
you can again apply all the cheuqes, and upon their bouncing, within 15 days send legal notice to the individual. thereon, if you do not receive a reply, file a case in court. the usual time period for court issuing NBW is 6-12 months, if person fails to show up.
