How to Sign European Contracts from India in 2026
If your business signs contracts with EU clients, sooner or later you will hit a procurement gate that demands an eIDAS Qualified Electronic Signature. This guide explains the three situations you will face, why your usual Indian signing tool will not work for the strictest one, and how to set up a QES path in under 10 minutes.
The three situations you will encounter
Not every EU contract needs the same signature level. Knowing which is which saves you procurement friction and unnecessary cost.
- 1
Situation 1 — Your EU client sends a contract pre-formatted for DocuSign or Adobe Sign
This is a Simple Electronic Signature (SES). Legally valid under eIDAS but with low evidentiary weight. Acceptable for everyday commercial documents (purchase orders, NDAs at non-confidential vendors, simple service orders).
- 2
Situation 2 — Your EU client requires eIDAS Advanced (AES)
An AES uniquely identifies the signer and is tamper-evident. Common for mid-value contracts, supplier framework agreements, and most B2B SaaS subscriptions. Most enterprise e-signature platforms (including Certyneo on lower plans) can deliver this.

Situation 3 — Your EU client requires eIDAS Qualified (QES)
QES is the highest level. Required for finance contracts, M&A, regulated industries (pharma, healthcare, telecom), Data Processing Agreements, and most government tenders in EU Member States. This is where your usual Indian signing tool stops working.
Every popular Indian signing platform stops short of eIDAS QES — for legitimate technical reasons.
Aadhaar eSign is not eIDAS-compliant
Aadhaar eSign is recognised under Section 3A of the IT Act 2000 in India but is not on the EU Trust List. There is no QSCD in the cryptographic flow, and the identity proofing (Aadhaar OTP) does not meet the eIDAS notified eIDV standard.
DSC tokens are PKI but not eIDAS-qualified
Indian DSC tokens (Class 2, Class 3) are PKI-based and closer to eIDAS in principle, but they are not issued by a Qualified Trust Service Provider on the EU Trust List, and they typically lack the ETSI EN 319-compliant audit trail required by eIDAS Article 26.
DocuSign and Adobe Sign in their default Indian configuration deliver SES, not QES
These platforms can deliver QES in select EU configurations, but the default flow most Indian customers use produces an SES — the lowest level. Upgrading typically requires a special enterprise plan with multi-region setup.
What 'eIDAS-qualified' actually requires
Identity proofing
Either face-to-face verification by an EU-notary or eIDV operator, OR a notified eIDV scheme. From India, this means passport-based verification with a live biometric check.
Qualified Signature Creation Device (QSCD)
A hardware security module certified to Common Criteria EAL4+. Operated by the QTSP — you do not need to acquire or manage this hardware yourself.
Qualified Trust Service Provider (QTSP)
An organisation listed on the official EU Trust List, regulated under eIDAS Article 17 by its Member State's national supervisory body.
The identity-proofing step from India
The most common blocker for Indian signers is the identity-proofing step. Here is how it works in practice with Certyneo:
1. Indian passport
You will need an Indian passport — the machine-readable zone is scanned and verified against international document standards. PAN, Aadhaar, voter ID and driving licence are not accepted under eIDAS rules.
2. Live selfie biometric match
A 5-second live selfie is matched to your passport photo. The biometric check satisfies the eIDAS 'liveness' requirement.
3. OTP confirmation
An OTP to your registered mobile phone confirms ownership. This binds the QES certificate to a specific phone number for future re-authentication.
4. Done in 4-7 minutes
First-time onboarding completes in 4 to 7 minutes from any Indian state. Every subsequent QES signature is instant.
What if you only have Aadhaar?
If you do not have an Indian passport, the eIDAS QES path is currently not available. We recommend applying for a passport (e-passport renewal is available online for existing passport holders) — the marginal cost is justified by the volume of EU contracts you will be able to sign.
Case study: a Bangalore SaaS signing a German Data Processing Agreement
A Bangalore-based SaaS company providing analytics tools to a German pharmaceutical manufacturer needed to renew its Master Services Agreement and Data Processing Addendum. The German procurement team's template specified eIDAS QES per Article 26 of Regulation (EU) 910/2014.
Before
Before Certyneo: the Indian signer was using Aadhaar eSign for all domestic contracts. The German legal team rejected the Aadhaar eSign on the DPA renewal. The contract was blocked for 18 working days while procurement evaluated alternatives.
After
With Certyneo: the Indian signer onboarded in 6 minutes via Indian passport scan. The QES was executed the same afternoon. The German legal team accepted the signature automatically — no additional verification, no procurement escalation. Closing happened 18 days earlier than the previous DPA renewal cycle.
Outcome
Same Indian signer is now used for all subsequent EU contracts across this client and three additional EU customers. Estimated procurement friction saved: 60-80 working days per year.
Pricing and how to start
Certyneo QES is billed at €9.90 per signature, with no subscription requirement and no minimum volume. For pricing scenarios at your expected volume, see our pricing page for Indian businesses.
Note: Aadhaar is not accepted for eIDAS identity proofing. Indian passport is the supported document for first-time signers.
