138 N.I

Jurisdiction to file complaint under NI Act arises on four planes - (a) where complainant resides (b) where complainant's bank is situate (c) where the cheque bounced and (d) where the accused is residing. Now the complainant does not consider the convenience of the accused and hence the option (d) is ruled out.  If the complainant is residing or having his head office in Bangalore or if the cheque was bounced at a branch of the bank in Bangalore, then the complainant is justified in filing the complaint at Bangalore Court.  Your friend has no choice but to attend the court hearings at Bangalore.
