eSignature legality summary
A contract is not unenforceable merely because it was concluded electronically, provided it meets the essential elements of a valid contract under ICA section 10 (competent parties, free consent, lawful consideration, lawful object). Private contracts generally do not require a signature at all to be valid. Separately, stamp-duty rules (the Indian Stamp Act and state stamp acts, several of which now cover electronic records) may apply.
Types of permitted electronic signature
The ITA recognizes an “electronic signature” that is (1) “reliable” and (2) uses an authentication technique listed in the Second Schedule. “Reliable” generally requires the signature/authentication data to be uniquely linked to and under the sole control of the signatory, tamper-evidence for both the signature and the document, an audit trail, and — for digital signatures — a certificate from a licensed Certifying Authority. The Second Schedule recognizes Aadhaar e-KYC e-Sign and licensed-CA key-pair (HSM) methods. A plain, non-ITA electronic signature can still support a valid contract, but only an ITA-compliant signature carries the ITA’s evidentiary advantage.
Documents that may be signed electronically
Most commercial agreements can be signed electronically. With an ITA-compliant signature, a challenger bears the burden of proving invalidity; with a non-ITA signature, the party relying on it must prove the contract satisfied the ICA’s essentials.
Use with caution / not typically appropriate
Stamping obligations may apply to electronic instruments in many states. For documents that need the ITA’s evidentiary weight, use an Aadhaar e-Sign or a licensed-CA digital signature.
