Aadhaar eSign

Aadhaar eSign lets a person sign a document electronically by authenticating with their Aadhaar number and a one-time password, producing a legally valid signature under India's IT Act for most documents.

E-signature platforms like Leegality, Digio and Zoho Sign offer Aadhaar eSign. Note that some instruments (certain powers of attorney, wills, etc.) cannot be signed electronically, and stamp duty may still apply.
