Protect confidential information with an NDA that is properly stamped and properly signed — fully online. Whether you already have a draft or need one built from scratch, DigitalPatra puts it on a genuine government e-stamp for the correct Karnataka duty and arranges Aadhaar eSign for both parties — no notary, no stamp-vendor visit, no waiting days for a signed copy. Flat ₹500 service fee plus a fixed ₹500 stamp duty: ₹1,000 all-in, confirmed before you pay.
Two ways to get your NDA e-stamped
Already have a draft?
Upload your NDA — from a lawyer, a template, or a past deal — and we e-stamp it and arrange Aadhaar eSign for both parties. ₹500 + ₹500 duty.
Nothing drafted yet?
Pick mutual or one-way confidentiality, set the term, choose your clauses — we draft it, e-stamp it, and route it for signature. ₹500 + ₹500 duty.
Only need the e-stamp certificate itself — no drafting, no eSign? See our Express option (₹200 + duty).
What stamp duty applies to an NDA in Karnataka?
An NDA is stamped under Article 5(J) — Agreement (in any other cases) of the Karnataka Stamp Act, 1957: a fixed duty of ₹500, whatever the value or duration of the confidential relationship it covers. Combined with our flat ₹500 service fee, the total is always ₹1,000 — no calculator, no surprises, and the duty is never marked up. The e-stamp carries a unique certificate number anyone can verify on the government portal. See how this compares to what other providers charge on our provider comparison page.
Who typically needs an e-stamped NDA
Founders & startups
Sharing a pitch deck, cap table, or product roadmap with an investor, advisor, or potential co-founder before terms are finalised.
Freelancers & consultants
Getting access to a client's internal data, codebase, or business plans before a project formally kicks off.
Businesses hiring or vendoring
Bringing on a new employee, contractor, or vendor who will see pricing, customer data, or proprietary processes.
Two companies exploring a deal
Due diligence, partnership talks, or an M&A conversation that needs confidentiality before anything is signed.
Does an Aadhaar-eSigned NDA hold up if there's a breach?
Aadhaar eSign is legally recognised under Section 5 of the Information Technology Act, 2000, and an e-stamped, eSigned document is court-ready evidence — both the identity of each signer and the confidentiality terms they agreed to are on record, with a verifiable government e-stamp certificate and a full signing audit trail. Read the fuller legal breakdown on our legality explainer.
Other documents on the same flow
The same e-stamp + Aadhaar eSign pipeline that handles NDAs also covers rental agreements, affidavits, partnership deeds, loan agreements, service and consulting agreements, PG agreements, and MOUs.
NDA FAQs
Is an e-stamped NDA legally valid in Karnataka?
Yes. A Non-Disclosure Agreement executed on a government e-stamp for the correct Karnataka stamp duty, and signed by both parties via Aadhaar eSign, is a validly stamped, validly signed contract. Aadhaar eSign is legally recognised under Section 5 of the IT Act, 2000, so the result is court-ready evidence if the NDA is ever breached and disputed — and the e-stamp certificate number can be independently verified on the government (SHCIL) e-stamping portal.
How much stamp duty does an NDA attract in Karnataka?
A Non-Disclosure Agreement is stamped as an "Agreement (in any other cases)" under Article 5(J) of the Karnataka Stamp Act, 1957 — a fixed duty of ₹500, regardless of the value or duration of the arrangement it protects. Add our ₹500 service fee and the total for a fully drafted, e-stamped, Aadhaar-eSigned NDA is a flat ₹1,000 — confirmed before you pay, never marked up.
Do I need a lawyer to draft the NDA, or can DigitalPatra do it?
Either way works. If you already have an NDA drafted — from a lawyer, a template, or a previous deal — upload it as-is at /upload-document and we e-stamp it and arrange Aadhaar eSign. If you haven't drafted anything yet, use /build-document to pick mutual or one-way confidentiality, term, and the clauses you need, and we generate the document for you.
Can both parties sign from different cities, or even different countries?
Yes. Each signer gets an OTP to their Aadhaar-linked mobile number and signs from their own phone — identity verified against the Aadhaar database, with a full audit trail baked into the PDF. Founders, investors, contractors and vendors sign an NDA from wherever they are, the same day, with no printing, courier, or notary visit.
I just need the e-stamp paper for an NDA I already have finalised — no signing needed yet. Can I get just that?
Yes — that's our Express option: ₹200 service fee plus the ₹500 fixed NDA duty (₹700 total), no drafting and no Aadhaar eSign, just the genuine government e-stamp certificate for the NDA, printed and posted within Bangalore in 2–24 hours. See /estamp-paper for details, or message us on WhatsApp to order.
