eSignature Legality in India 2026 — NDA agreement signed via Aadhaar, valid under IT Act 2000 and Rules 2021

Coming soon. This post is being written. The outline below is what it will cover. To get notified when it goes live, subscribe to the newsletter.

Outline

This post will be the definitive plain-English guide to eSignature legality in India. It will cover:

  • Information Technology Act 2000, Section 3A — what it actually says
  • The Second Schedule and notified electronic signature techniques
  • Bharatiya Sakshya Adhiniyam 2023 Section 63 (formerly Indian Evidence Act §65B)

The two main eSign techniques

  • Digital Signature Certificates (DSC) — when required, how to obtain
  • Aadhaar eSign — how Section 3A applies

Document types — what’s in, what’s out

  • Standard business contracts (NDAs, MSAs, employment) — in
  • Statutory filings (GST, MCA) — DSC only, not generic eSign
  • Documents specifically excluded (wills, sale deeds, certain POAs, trust deeds)
  • State-law variations for real estate and stamp duty

What an audit trail must contain

  • Identity attribution (IP, device, authentication method)
  • Timestamp integrity
  • Document hash for tamper detection
  • ESP-issued certificate chain

Court admissibility

  • Section 63 BSA 2023 requirements
  • Section 65B compliance certificates (still relevant for legacy cases)
  • Real-world case law on electronically signed contracts

Practical compliance checklist

  • A short checklist for SMBs to confirm their eSign workflow holds up
