2. It can be drafted and lodged by the aggrieved person also.
3. Filing of complaint against NC offense has no sense at all and police will refuse to record it.
4. A complaint against a NC offense will hardly have any chance to be referred to while filing any complaint against cognisable offences later on.
5. It is not understandable without getting further details as to how a complaint against a NC offence can be tugged with a future complaint u/s302 and 306 of IPC. If there is any pre-planned attempt to fix any body at a future date then it may be unearthed by the lawyer of the other side. Moreover, in case of complaint u/s306 of IPC, the note left by the person committing suicide is of utmost importance to fix the charge.
6. No. Copy of complaint against the accused is not required to be sent to the accused.
