Is Aadhaar eSign legally valid in India?
Last reviewed:
Short answer
Yes. Aadhaar eSign is a legally recognised electronic signature in India. It is an e-authentication technique notified under the Second Schedule to the IT Act, 2000, delivered through CCA-licensed eSign Service Providers using Aadhaar e-KYC and an OTP or biometric. A validly completed Aadhaar eSign carries the same legal standing as a handwritten signature, subject to the same First-Schedule document exclusions.
What is Aadhaar eSign and how does it work?
Aadhaar eSign is an online electronic-signature service that lets an Aadhaar holder sign a document remotely. The signer’s identity is verified through Aadhaar e-KYC (using an OTP sent to the registered mobile number, or a biometric), after which a licensed eSign Service Provider (ESP) facilitates a digital signature backed by a certificate issued by a Certifying Authority. The whole flow is regulated by the Controller of Certifying Authorities (CCA) under the IT Act.
Is Aadhaar eSign legally valid in India?
Yes. Aadhaar eSign is an electronic-signature technique recognised under the Second Schedule to the IT Act, 2000, so a document signed with a valid Aadhaar eSign is legally enforceable and is treated as a secure electronic signature. This gives it a statutory presumption of authenticity that a simple typed or scanned signature does not automatically enjoy.
Is Aadhaar eSign admissible as evidence in court?
An Aadhaar-eSigned document is an electronic record, and to be admitted in court it must be proved in accordance with the rules for electronic evidence — Section 65B of the Indian Evidence Act, 1872 (now Section 63 of the Bharatiya Sakshya Adhiniyam, 2023, in force from 1 July 2024), which typically requires an accompanying certificate. The audit trail generated by the ESP (timestamp, e-KYC reference and transaction ID) helps establish authenticity.
What are the limits of Aadhaar eSign?
Aadhaar eSign cannot be used for documents excluded by the First Schedule to the IT Act (wills, most negotiable instruments, powers-of-attorney, trusts and immovable-property transfers). It also depends on the signer holding a valid Aadhaar with a linked mobile number, and its use must comply with the Aadhaar Act, 2016 and applicable data-protection and consent requirements. Some public authorities and registrars may still insist on physical signatures.
