Legal recognition of eSignatures in India

eSignatures are recognized under the Information Technology Act, 2000 (IT Act), which provides the primary legal framework for the use of electronic records and digital signatures in India. The Electronic Signature or Electronic Authentication Technique and Procedure Rules, 2015 (ESEATPR) builds on it by specifying the technical and procedural requirements for the creation, authentication, and validation of eSignatures.

Additionally, the Indian Contract Act, 1872, plays an indirect yet foundational role in establishing the legality of eSignatures in India by setting the groundwork for the enforceability of agreements, including those executed electronically.

The IT Act aligns with international standards like the UNCITRAL Model Law on Electronic Commerce, ensuring interoperability and acceptance of eSignatures across borders.

Enacted in 2000 and updated periodically, including significant amendments in 2008, the IT Act grants eSignatures the same legal validity as handwritten signatures, provided they meet specific technical and procedural requirements.

This legal recognition has facilitated the secure and efficient adoption of eSignatures in both government and private-sector transactions, enabling India to move toward a more digital-first economy.

Types of electronic signatures accepted in India

In India, the Information Technology Act, 2000 (IT Act) recognizes two main types of eSignatures that are legally accepted: Digital signatures and Aadhaar-based eSignatures.

Here's a breakdown:

Type of eSignature	Description
Digital Signatures or Digital Signature Certificates (DSC)	• Use asymmetric cryptography (a pair of private and public keys) and a hash function to ensure document integrity and authentication. • Stored on a special device called a USB token or hosted on a server and protected with a password. • Highly secure and tamper-proof. • Uniquely linked to the signer. • Verifiable using the public key of the signer. Examples in use: Signing contracts, invoices, and government filings. Common in business transactions requiring high levels of security. Issued by/regulated by: Issued by licensed certifying authorities (CAs) regulated by the Controller of Certifying Authorities (CCA) under the IT Act.
Aadhaar-based eSignatures	• Online eSignature service linked to an individual’s Aadhaar number. • Enables remote signing using OTP or biometric verification. • Simple and accessible, ideal for individuals and businesses. • Digital signing of agreements, bank account opening forms, and eGovernance applications. Examples in use: Widely used in public and private sectors for fast, paperless transactions. Issued by/regulated by: Regulated by Ministry of Electronics and Information Technology (MeitY).

Requirements for legality of eSignatures in India

To ensure that eSignatures are legally binding in India, they must meet specific criteria as outlined under the Information Technology Act, 2000 (IT Act). These include:

1. Consent of all parties

All parties involved must consent to the use of eSignatures for executing the agreement or transaction. This consent can be explicit or implied, based on the context of the agreement or established practices.

2. Identity verification

The identity of the signer must be verified to ensure authenticity. In India, this is often achieved through digital signatures issued by licensed certifying authorities or Aadhaar-based eSignatures that use OTP or biometric verification linked to the Aadhaar database.

3. Document integrity

The eSigned document must be tamper-proof, ensuring that any alteration after signing is detectable. Digital signatures achieve this by encrypting the document with a hash function.

4. Record retention and audit trails

eSigned documents should be retained in a manner that ensures their authenticity and accessibility over time. Audit trails, including timestamps and signer details, provide additional evidence of the signing process, further bolstering legal validity.

5. Unique linkage to the signer

The eSignature must be uniquely linked to the signer, ensuring it cannot be replicated or misused by others. Technologies like PKI (Public Key Infrastructure) ensure this linkage by associating the signer’s private key with their identity.

6. Adherence to regulatory standards

The eSignature must comply with the standards and guidelines issued by the Controller of Certifying Authorities (CCA) and the Ministry of Electronics and Information Technology (MeitY).

Limitations and exceptions

While eSignatures are legally recognized in India, certain documents and situations are excluded from their use. These exceptions primarily involve transactions and agreements that require a higher standard of authentication or traditional methods of execution.

Documents where eSignatures are invalid include:

Wills and testamentary documents: Wills require strict compliance with the Indian Succession Act, including witnesses and handwritten signatures, making eSignatures unsuitable.
Trust deeds: Creating or transferring trusts must follow formal procedures that typically require physical signatures and registration.
Negotiable instruments: Documents such as promissory notes and bills of exchange (except cheques) must comply with the Negotiable Instruments Act, which does not currently accommodate eSignatures.
Powers of attorney: These documents require authentication under the Powers of Attorney Act, necessitating physical signatures and, in some cases, notarization.
Contracts relating to immovable property: Agreements for the sale, lease, or transfer of immovable property must be executed and registered under the Registration Act, which mandates physical signatures.

There are also certain situations in which eSignatures can be challenged, including:

Cross-border transactions: While India aligns with international standards, certain jurisdictions may not recognize Indian eSignatures, creating challenges in cross-border agreements.
When identity verification is insufficient: eSignatures may be contested if the process of verifying the signer’s identity is inadequate or if tampering is suspected.

2. Maintain audit trails: Ensure that your eSignature process includes a detailed audit trail that records timestamps, IP addresses, and the sequence of actions. This documentation can be crucial for resolving disputes or verifying authenticity.

3. Verify identity: Implement robust identity verification measures, such as Aadhaar-based eSignatures or multi-factor authentication, to ensure the signer’s authenticity.

4. Ensure document integrity: Use solutions that protect the integrity of the signed documents through encryption and tamper-evident features, preventing unauthorized modifications.

5. Store signed documents securely: Keep electronically signed documents in secure, compliant storage systems to safeguard against data breaches and ensure long-term accessibility.
