Is a Digital Signature Legally Valid in India?
Under the Information Technology Act 2000, electronic signatures are legally valid in India for most business and personal transactions. However, certain documents like property sale deeds, wills and power of attorney require physical signatures witnessed by a notary. For routine business documents — employment letters, service agreements, freelance contracts — a digital signature is fully valid.
