Is digital stamping legal in India?
Yes. Digital stamping (also known as eStamping) is fully legal in India. eStamp certificates are issued through authorised collection channels and carry the same legal validity as physical stamp paper.
The legality is anchored in the Indian Stamp Act, 1899 (as adopted by each state), read with the Information Technology Act, 2000 — which recognises electronic records and digital signatures. Every eStamp carries a unique certificate number that can be verified with the issuing authority, making it enforceable in court.
Legally backed by
- Indian Stamp Act, 1899
- Information Technology Act, 2000
- Registration Act, 1908
