FIR vs NC Complaint: What's the Difference?

When someone approaches the police to report an incident, the type of complaint registered — an FIR or an NC entry — determines what happens next, and the difference matters far more than most people realise at the time.

First Information Report (FIR)

An FIR is registered for cognizable offences — serious crimes such as theft, assault, or fraud, where the police have the authority to investigate and arrest without needing prior court permission. Once an FIR is filed under Section 154 of the Code of Criminal Procedure, the police are legally obligated to investigate.

Non-Cognizable (NC) Complaint

An NC complaint is registered for less serious, non-cognizable offences, where the police cannot investigate or arrest without prior permission from a magistrate. It is often used for matters like minor disputes or defamation, and mainly serves as an official record rather than triggering an active investigation.

• FIR: cognizable offence, mandatory police investigation, arrest possible without a warrant
• NC complaint: non-cognizable offence, investigation only with magistrate's permission
• You can request a copy of either document — it's your right
• If police refuse to register an FIR for a cognizable offence, a complaint can be made to a superior officer or the magistrate directly

Why the distinction matters

Confusing the two can leave a genuine complaint without any real follow-up, or leave someone facing serious allegations without realising an active investigation has begun. If you're unsure which category your matter falls under, it's worth getting that confirmed before deciding your next step.
