For someone based in Chennai, the following is general information on fir registration and zero fir for someone in Chennai.
What a First Information Report is, how a Zero FIR lets you report a crime outside the local jurisdiction, and what to do if police refuse to register one.
The legal position
Under BNSS s.173, information about a cognizable offence can be given to police irrespective of the area where the offence was committed — this is what is commonly called a Zero FIR.
Information can be given orally or electronically. Where it is given electronically, it is treated as on record only once the informant signs it, which must happen within 3 days.
For offences under BNS ss.64-71, 74-79, or 124, the information must be recorded by a woman police officer.
The informant or victim is entitled to a free copy of the FIR under BNSS s.173(2).
Where this applies in Chennai
- The High Court with jurisdiction is the Madras High Court.
- Matters at the district level are generally handled at the Chennai City Civil Court or Small Causes Court.
- The relevant police authority is the Greater Chennai Police.
How this generally works
The usual sequence looks like this.
Report at any police station
You are not restricted to the police station with territorial jurisdiction over where the offence happened; any station must record it as a Zero FIR and transfer it.
Electronic complaints
If you report electronically (for example through a state e-FIR portal), sign the complaint within 3 days for it to be treated as filed.
If police refuse to register
Send a written complaint to the Superintendent of Police under BNSS s.173(4); if there is still no action, you may apply to the jurisdictional Magistrate.
Documents generally involved
- Identity proof of the complainant
- Any evidence already available (photographs, messages, documents, witness details)
- A written account of the incident with approximate dates and location
Common pitfalls
A few points are easy to get wrong.
- Waiting to approach the 'right' police station before reporting — a Zero FIR means you do not have to.
- Not signing an electronically filed complaint within the window, which can affect when it is treated as registered.
- Assuming a Zero FIR is a lesser or informal complaint — it carries the same legal weight once transferred to the appropriate station.
