STATUTORY & WORKFLOW FAQS

Frequently Asked Questions: Sign NDA Online

Is an electronically signed NDA legally enforceable in Indian courts?

Yes. Non-Disclosure Agreements (NDAs) are governed by the Indian Contract Act, 1872 and the Information Technology Act, 2000. Because NDAs do not fall under the excluded categories of the First Schedule of the IT Act, an NDA signed electronically via Inscriben is 100% legally binding and admissible in court.

What if one party is in India and the other party is in the US or Europe?

Inscriben seamlessly handles cross-border NDAs. Your Indian entity can sign using Aadhaar eSign or Inscriben PAdES Sign (compliant with the IT Act, 2000), while your US or European counterparty signs using Inscriben's ESIGN/UETA and eIDAS-compliant electronic signature on the same document.

Can I sign a one-off NDA right now for free without registering?

Yes! If someone sent you an NDA PDF and asked you to sign and return it, you can use our Free Online PDF Signer tool (/tools/sign-pdf/) to draw or type your signature, stamp the date, and download the signed PDF immediately with zero signup required.

How do I prove the NDA wasn't altered after signing?

Every NDA signed through Inscriben is sealed with a SHA-256 cryptographic hash and PAdES PKCS#7 signature. You can drop the PDF into inscriben.com/verify/ at any time in the future to prove that not a single byte of the agreement was modified since the moment of signing.
