Electronic contracts are enforceable in India under Section 10A of the Information Technology Act, 2000, which says an agreement is not unenforceable merely because it was formed electronically, and can be authenticated using digital signatures (Section 3) or electronic signatures such as Aadhaar eSign (Section 3A), with electronic evidence rules now governed by Section 63 of the Bharatiya Sakshya Adhiniyam, 2023 rather than the old Evidence Act.
Validity of e-contracts -- Section 10A, IT Act 2000
Section 10A of the Information Technology Act, 2000 provides that a contract is not unenforceable solely
because it was formed through electronic means -- covering click-wrap agreements, email exchanges, and other
online contracting methods, provided the underlying essentials of a valid contract under the Indian Contract
Act, 1872 are otherwise met (offer, acceptance, consideration, and so on). This is particularly relevant for
NRIs, who routinely execute service agreements, employment contracts, and vendor agreements with Indian
counterparties entirely online without ever being physically present in India -- Section 10A confirms that
the cross-border, electronic nature of the transaction is not itself a barrier to enforceability.
Digital signatures and electronic signatures
Section 3 of the IT Act authenticates electronic records through digital signatures based on asymmetric
cryptography and a hash function, issued by licensed Certifying Authorities regulated by the Controller of
Certifying Authorities (CCA) under the Ministry of Electronics and Information Technology. Section 3A, added
by the 2008 amendment, introduced a technology-neutral “electronic signature” category, which
enabled the widely used Aadhaar eSign framework -- an OTP or biometric-based electronic signing method linked
to a person’s Aadhaar number.
Electronic evidence -- now Section 63 of the BSA, not Section 65B of the old Evidence Act
The Indian Evidence Act, 1872 was repealed and replaced by the Bharatiya Sakshya Adhiniyam, 2023 (BSA),
effective 1 July 2024. The old Section 65B certification requirement for admitting electronic evidence is now
Section 63 of the BSA, which broadly retains the certification framework established by the Supreme Court in
Anvar P.V. and Arjun Panditrao Khotkar, while widening the list of persons who can issue the required
certificate. Any dispute over an e-contract that ends up in litigation will need to satisfy Section 63 BSA to
have the electronic record admitted as evidence -- content or advice citing “Section 65B” should
now refer to Section 63 BSA.
Is a contract signed only by email exchange legally binding in India?
It can be, if the essentials of a valid contract are otherwise present -- Section 10A of the IT Act
confirms that the electronic form of the agreement is not, by itself, a reason to treat it as unenforceable.
Being able to prove the exchange (and produce it as admissible evidence under Section 63 BSA if needed) is a
separate, practical concern from its underlying legal validity.
Is Aadhaar eSign as legally valid as a physical signature for contracts?
Yes -- Aadhaar eSign is a form of electronic signature recognized under Section 3A of the IT Act, and
documents signed this way carry the same legal recognition as documents bearing digital signatures under
Section 3, subject to the technology meeting the reliability requirements the Act and its rules specify.
Do I need to produce a special certificate to use a WhatsApp chat or email as evidence in an Indian court?
Generally yes, for secondary electronic evidence -- Section 63 of the Bharatiya Sakshya Adhiniyam, 2023
(replacing the old Section 65B Evidence Act requirement) requires a certificate confirming how the electronic
record was produced before it can be admitted, unless the original device itself is produced in court.
