Direct answer

Aadhaar eSign authenticates a signer online and applies an electronic signature through an authorized provider. DSC uses a certificate issued by a licensed Certifying Authority. eStamping pays and records stamp duty; it is not a signature. NeSL signing combines digital document execution, eSign, eStamping, and information-utility evidence for eligible financial workflows.

Definitions

Aadhaar eSign

An online electronic-signature service where a signer authenticates through Aadhaar-linked mechanisms and an authorized eSign provider applies a digital signature certificate for that transaction.

Digital Signature Certificate

A certificate issued by a licensed Certifying Authority under India’s digital-signature framework to bind a subscriber identity to signing keys.

eStamping

Electronic payment and record generation for stamp duty. It supports enforceability of stamped instruments but does not itself prove signer consent.

NeSL digital document execution

A digital execution service from National e-Governance Services Ltd that can support eSign, eStamping, evidence records, and Information Utility workflows.

Practical workflow

  1. Classify the document

    Identify whether the document needs signature, stamp duty, registration, witness steps, board authority, or financial-information evidence.

  2. Choose signer identity method

    Use Aadhaar eSign for eligible online signers or DSC where certificate-based signing is required or preferred.

  3. Calculate stamping needs

    Check state-specific stamp duty, instrument type, value, party details, and whether eStamping is accepted for the transaction.

  4. Execute and capture evidence

    Record signer identity, consent, timestamp, IP/device data where applicable, certificate details, stamp certificate, and final document hash.

  5. Store and reconcile

    Save executed documents, audit trails, stamp records, NeSL evidence, and renewal or obligation metadata in the legal repository.

Comparison

MethodPrimary purposeTypical enterprise use
Aadhaar eSignRemote electronic signature through Aadhaar-linked authentication.High-volume customer, vendor, employee, and loan-document signing where allowed.
DSCCertificate-based digital signing by an identified subscriber.Authorized signatory signing, filings, board documents, procurement, and controlled internal approvals.
eStampingStamp duty payment and certificate generation.Agreements and instruments where stamp duty must be paid before or around execution.
NeSL DDEDigital document execution with signing, stamping, and evidence services.Loan documentation, financial contracts, and workflows needing Information Utility evidence.

Limitations and exceptions

  • Stamp duty is state and instrument specific, so a signing workflow should not assume one stamping rule across India.
  • Aadhaar eSign availability depends on signer eligibility, consent, authentication success, and provider coverage.
  • Some documents may require physical execution, registration, witnesses, notarization, or additional legal checks outside a signing platform.

Metrics methodology

Choose the execution method by separating identity proof, consent capture, stamp-duty compliance, evidence retention, and repository controls. Metrics should track signing completion rate, signer failure reasons, stamping exceptions, rework, turnaround time, and document rejection rate.

FAQs

No. eStamping records stamp duty payment. eSigning records signer consent and applies an electronic or digital signature. Many documents need both.

DSC may be preferred when the signer is an authorized certificate holder, when a filing or counterparty expects certificate-based signing, or when internal policy requires DSC controls.

NeSL can support digital document execution and Information Utility evidence for eligible financial contracts, which is valuable for banks, NBFCs, and loan-document workflows.
