  • According to the Information Technology Act, 2000 (IT Act) digital signatures are recognised by the law and have the same legal standing as physical ones.
  • By providing digital signature certificates and verifying that legal requirements are met, certification bodies play a significant part in the authenticity of digital signatures.
  • As long as they comply with the legal conditions set forth in the IT Act, electronic records bearing digital signatures are admissible as evidence in court and are presumed to be legitimate.


In the era of electronic transactions and paperless communication, digital signatures have emerged as a critical instrument. They offer a safe method for authenticating and confirming the signer's identity, protecting the accuracy and irrefutability of electronic data. Digital signatures have developed into a crucial part of the digital economy with the rise of e-commerce and online transactions. Compared to traditional signatures, digital signatures have more advantages in terms of security, efficacy, and cost. They simplify the process of signing and transmitting electronic documents, do away with the need for physical signatures, and lessen fraud and forgery risk. 

In addition, the use of digital signatures is essential to guarantee that electronic transactions are compliant with laws and regulations, such as those outlined in the Information Technology Act, 2000. The Information Technology Act is the main law controlling electronic transactions and digital signatures in India is the Information Technology Act, 2000 (IT Act). By establishing their legal validity and admission in court, the Act establishes a framework within which electronic records and digital signatures may be used and recognised. The Act also specifies penalties for offences involving electronic signatures and records, as well as standards and procedures for digital signature certifications and certifying organisations. The IT Act has aided in encouraging the usage of electronic transactions and e-commerce in India by establishing a clear legal framework for digital signatures.

Digital signatures are becoming a crucial tool for both organisations and consumers due to the rise of computerised transactions and paperless communication. An electronic record's validity and integrity may be verified using a digital signature, which acts as a secure electronic mark. An Indian law that recognises the legitimacy and importance of digital signatures is the Information Technology Act, 2000 (IT Act). In order to determine if digital signatures are legitimate under the IT Act, this article will look at the rules for certification authority, the legal requirements for their usage, and the admission of electronic documents with digital signatures as evidence in courts. Additionally, it will take into account how India's position on digital signatures compares to that of other countries.


The Indian legal basis for digital signatures is outlined in the Information Technology Act, 2000 (IT Act). The Act establishes a clear legal framework for the use of digital signatures and electronic records in electronic transactions by recognising their admissibility and legal validity. The following are some of the most important clauses of the IT Act that deal with digital signatures:

Definition of digital signature:

A digital signature is described in Section 2(1)(p) of the IT Act as "authentication of any electronic record by the subscriber by means of a digital process or procedure in line with the provisions of Section 3."

Legal recognition of electronic records and digital signatures:

Section 3 of the IT Act states that, where a law requires that information or another matter be in writing, typewritten, or printed form, that requirement shall be deemed to have been satisfied if that information or other matter is provided or made available in an electronic format.

Use of digital signatures for authentication of electronic records:

According to Section 4 of the IT Act, if any law requires that a document, record, or piece of information be signed or bear the signature of a person, the prerequisite is considered to be satisfied if such document, record, or piece of information is verified using a digital signature, regardless of what else may be stated in that law.

Creation and verification of digital signatures:

The process for creating and verifying digital signatures is outlined in Section 5 of the IT Act. It outlines the specifications for certifying authority as well as the requirements for the digital signature certificate, which includes the usage of encryption and hashing methods.

Time and place of dispatch and receipt of electronic records:

The timing and location of the dispatch and reception of electronic records must be determined, according to Section 10A of the IT Act. It states that in cases where both the sender and the recipient have consented to using electronic communication, an electronic record is dispatched when it enters a computer resource that is not under the originator's control, and it is received when it enters a computer resource that is not under the addressee's control.


The Information Technology Act of 2000 (IT Act) recognises the legality of electronic documents with digital signatures and permits their use as evidence in legal proceedings. The following are some of the main clauses pertaining to the legality of digital signatures in court cases under the IT Act:

Section 4 of the IT Act establishes a legal presumption of authenticity for electronic records with digital signatures, stating that when an electronic record has been authenticated using a digital signature, that electronic record shall be deemed to be a document duly signed by the person whose digital signature certificate is in possession, unless otherwise specified. Admissibility of electronic documents and digital signatures as evidence in court: Section 65B of the Indian Evidence Act, 1872 specifies that electronic documents and digital signatures are admissible as evidence in court. It outlines the prerequisites for the acceptance of electronic evidence, including that the record must be produced in accordance with established procedures and be accompanied by a certificate from a person in charge of the computer resource outlining the pertinent information about the record.

Legal requirements for certificates of digital signature and certification authorities: The legal requirements for digital signature certificates and certification authority are outlined in Section 35 of the IT Act. It outlines the specifications for certifying authority as well as the criteria for digital signature certificates, which include the usage of encryption and hashing methods. Liability of certification authorities for issuing inaccurate or phoney digital signature certificates: Section 43A of the IT Act establishes the responsibility of certification authorities for issuing inaccurate or phoney digital signature certifications. It states that a body corporate that possesses, deals with, or handles any responsive personal information or data in a computer system that it owns, controls, or operates is liable for damages if it fails to implement and maintain reasonable security practises and procedures and as a result causes unlawful loss or wrongful gain to any person.

Overall, assuming that they adhere to the legal criteria and standards for digital signature certifications and certifying authority, digital signatures have legal validity and are accepted as evidence in court under the IT Act. Electronic records with digital signatures have a legal presumption of validity, and certification bodies may be held accountable for issuing false or fraudulent digital signature certifications.


Certain requirements must be satisfied for digital signatures to be legitimate. The following are some essential requirements that must be met in order for a digital signature to be accepted:

  • The data used to create the signature and the data used to verify the authenticity should only be related to the signatory or the authenticator.
  • The information needed to create the e-signature should be under the signer's control at the moment of signing.
  • After attaching the e-signature or data, any modifications or revisions are visible.
  • The information technology (Certifying Authorities) Rules, 2000's Form C of Schedule IV's e-authentication specification is the basis for its issuance by a Certifying Authority.

For the following reasons, section 1(4) of the Information Technology Act of 2000 does not apply to electronic signatures:

  • A negotiable instrument, as defined by Section 13 of the NI Act of 1881, other than checks.
  • An authority granted pursuant to Section 1A of the Power of Attorney Act of 1882.
  • A trust as outlined by Section 3 of the Indian Trust Act of 1882.
  • Any agreement pertaining to the purchase, lease, or transfer of real estate, or any interest therein.
  • A will is a legal document that includes all testamentary dispositions as described in Section 2(h) of the Indian Succession Act, 1925.


The United States, the United Kingdom, Australia, Singapore, and Japan are among the nations that have passed legislation governing the use of digital signatures. These regulations, which aim to protect the legitimacy, integrity, and non-repudiation of digital signatures, are largely analogous to the IT Act of India. Nevertheless, depending on the jurisdiction, there could be variations in the precise legal rules and requirements for digital signatures. The Model Law on Electronic Signatures, created by the United Nations Commission on International Trade Law (UNCITRAL), offers a framework for the legal acceptance and validity of digital signatures. For nations creating their own legal frameworks for digital signatures, including India, the UNCITRAL Model Law is a helpful resource. The Indian IT Act offers a strong legal foundation for the use of computerised signatures in digital transactions and is generally in accordance with the UNCITRAL Model Law.

The World Trade Organization's Agreement on Trade Facilitation and the United Nations Convention on the Use of Electronic Communication in International Contracts are just two of the international treaties and agreements that have been signed to support electronic commerce and the use of digital signatures. These agreements guarantee the legal legitimacy and validity of digital signatures across various nations and offer a framework for the use of electronic signatures in cross-border transactions.


The Central Government has designated a Controller of Certifying Authorities who has the authority to award the Certifying Authorities a licence to issue digital signature certificates to the users in order to demonstrate the authenticity of an electronic document. A digital certificate of this type includes the owner's name, public key, expiration date, serial number, digital signature, and issuer's name. Since it is governed by the Central Government, only digital papers created by certifying agencies are regarded as trustworthy.

These certificates come in a variety of forms and can be used for signing, encryption, or both signing and encryption. Anyone who wants to get a certificate of digital signature can submit an application for the issuing of a digital certificate to the certifying authority along with the required payment.


The government accepts electronic documents with digital signatures for authentication in a number of departments. These agencies include, among others, the Ministry of Finance, the Department of Revenue, and the Ministry of Corporate Affairs. The Ministry of Corporate Affairs prefers electronic filings to be executed using digital signatures. Even the RBI has given some small fiancé banks and payments banks permission to use electronic verification to confirm that customers have read and agree to the bank's terms and conditions.

The validity of e-signatures to be used in India underwent a significant shift as a result of the Electronic Signature or Electronic Authentication Technique and Procedure Rules, 2015. It strengthened the Controller of the Certifying Authority's authority and enabled it to control how e-authentication methods are used. Only the Central Government has the power to validate electronic signatures. It possesses the ability to provide the many technical and dependable conditions necessary for an e-signature to be considered legitimate.


In conclusion, firms and people doing electronic transactions in India must carefully consider the legality of digital signatures under the Information Technology Act. The Act defines digital signatures and details their legal recognition, validity, and usage requirements. It also offers a thorough legal framework for their use. This legal framework has major consequences for organisations and people that use digital signatures for online transactions since it increases the security, effectiveness, and simplicity of online transactions while reducing the need for paper-based record. The Information Technology Act's legal framework for digital signatures is consistent with worldwide best practises and is largely comparable to other legal frameworks for digital signatures across the world. The legal framework for digital signatures in India still has room for improvement, including modernising the standards for digital signature certificates and certification bodies and streamlining the legal requirements for the generation and validation of digital signatures.

Overall, the Information Technology Act's recognition of digital signatures as genuine offers a sound legal foundation for their usage in electronic transactions in India and supports the expansion of e-commerce and paperless transactions throughout the nation. The legal foundation for digital signatures will continue to be essential in assuring the validity, integrity, and non-repudiation of electronic transactions as technology develops and digital transactions become more widespread
