The skills are the same everywhere. The legal and licensing rules differ by country, so each course carries a country card that follows your edition.

Electronic evidence and lawful access in India

● Full coverage
About this card
The 2023 evidence and criminal-procedure laws are in force, and the main rules on electronic records are settled. Three points are still open: who may sign the expert part of the section 63 certificate, whether an accused can be made to give a password, and when the Telegraph Act repeal takes effect. Checked on 12 November 2026.
What you must do
  1. File a section 63(4) certificate, in the Schedule form and with the hash value, each time you submit a copy of an electronic record.
  2. Have the certificate signed by the person in charge of the device and by an expert. Ask your prosecutor what expert the court accepts.
  3. Record every search and seizure on audio-video, preferably a mobile phone, and send the recording to the Magistrate without delay.
  4. Write down the sequence of custody of every electronic device you seize.
  5. Ask for data or devices only under a lawful power, such as a notice under BNSS s.94.
  6. Intercept only under a written order of the competent authority. Unlawful interception is an offence.
  7. Treat compelled passwords as unsettled law, and take legal advice before you ask for one.

Common questions

Does it teach how to intercept communications?
No. It explains what telecom and network records show, what they cannot prove, and the legal controls on interception. It teaches no technique for covert access.
Will it help me read a call record?
Yes. It walks through call records, cell-site evidence and IP addresses, with the common ways people over-claim what they show.
When can I take the final assessment?
When you have marked complete the units that are core on your path. The final draws its questions from those units. If you did not choose a role, every unit counts.
Is this legal advice?
No. The course teaches how the law and practice work. For a real case, follow your organisation's procedures and take advice from a qualified lawyer where you work.
Is this an official licence or certification?
No. LEA.Training is a private training provider. A course builds knowledge and readiness and ends with a Record of Completion. It is not a licence, a regulator's certificate or an accreditation, and it is not endorsed by any government agency.
Can I try it before I pay?
Yes. The first lesson of each course is open to read, with no sign-up.
How do I get a Record of Completion?
Finish the lessons, then pass the course’s final assessment with 70% or more. Your Record carries a number and a QR code that anyone can check on the verify page. It shows only your name (or initials), the course, the date and its status.
How long do I keep access?
Paid access lasts 12 months from the day you buy. You can study at your own pace and come back to any lesson during that time. Your Record of Completion stays verifiable after access ends.
Can I read the lessons in Hindi?
Yes. In the India edition you can switch a lesson to Hindi. The Hindi text is machine translated and checked by an AI reviewer, not yet by a human reviewer, so the English original is always one tap away.
Who sells the course, and how is tax handled?
In the India edition the seller is VSVSV (Vidhi Sangat Vidyut Saksya Vinaya) Tech Private Limited. Prices include GST and you get a GST tax invoice.
Can I buy seats for my team?
Yes. Agencies, firms, colleges and companies can buy seats, assign the right path for each role and see progress and results. Larger teams get a discount. See For organisations.
