In an era increasingly shaped by digital transformation, the legal system in India faces the pressing need to adapt traditional modes of service of notice to modern electronic platforms. This article critically examines the evolving legal recognition of email and WhatsApp as valid modes of serving legal notices, especially in the context of civil, commercial, and criminal proceedings. Drawing from statutory provisions, judicial pronouncements, and comparative international practices, the research explores whether these digital tools satisfy the fundamental principles of natural justice and procedural fairness.

Particular attention is paid to landmark judgments such as Kross Television India Pvt. Ltd. v. Vikhyat Chitra Production, Bharti Airtel Ltd. v. Union of India, and Indian Bank v. Satyam Fibres (India) Pvt. Ltd., which have acknowledged the evidentiary and procedural value of electronic communications. The paper also analyzes regulatory frameworks such as the Information Technology Act, 2000 and the Civil Procedure Code (Amendment) rules regarding electronic service.
