How to Prepare for a Criminal Investigation: A Lawyer's Checklist.

A Comprehensive Guide to Safeguarding Your Rights and Building a Strong Defense

When facing a criminal investigation in India, the stakes couldn't be higher. Your freedom, reputation, and future hang in the balance. The new Bharatiya Nagarik Suraksha Sanhita (BNSS), which replaced the Criminal Procedure Code in July 2024, has introduced significant changes that make proper preparation more critical than ever. This comprehensive checklist will guide you through every essential step to ensure your rights are protected and your defense is as strong as possible.

## Understanding the New Legal Landscape

The BNSS has transformed criminal investigations in India by mandating forensic investigation for offenses carrying punishment of seven years or more, introducing electronic modes for trials and proceedings, and allowing collection of biometric data even from non-arrested individuals. These changes mean that proper preparation has become even more crucial for anyone facing criminal charges.

The investigation process in India involves multiple stages: lodging of information, proceeding to the crime scene, preliminary inquiry, evidence collection, witness examination, and filing of charge sheet.

Understanding each stage helps you prepare more effectively for what lies ahead.

Exercise Your Fundamental Rights

- Invoke your right to remain silent immediately - anything you say can be used against you.

- Request legal representation before answering any questions.

- Understand that you have the right to know the reasons for any arrest under Articles 20, 21, and 22 of the Constitution.
