Aadhaar eSign

A signature your counterparty can complete on a feature phone.

No token, no software, no account. Docsliy routes the signature through a Certifying Authority licensed by the Controller of Certifying Authorities, so it carries the weight of a handwritten signature under the Second Schedule of the IT Act, 2000.

How it works

Four steps, and nothing to install

The signer needs a phone that receives SMS. That's the whole requirement.

  1. 01

    Send

    The agreement goes out with the signing request. Stamp duty, where it applies, is already settled.

  2. 02

    Authenticate

    The signer authenticates against their Aadhaar-linked mobile number by OTP, or by fingerprint or iris capture where the deal warrants it.

  3. 03

    Certifying Authority signs

    Authentication is performed by a CA licensed by the Controller of Certifying Authorities — not by Docsliy.

  4. 04

    Sealed

    The completed document returns with its signing record: timestamp, IP, device and authentication method.

Recognised signature types

Two ways to sign, both recognised in law.

The Information Technology Act, 2000 recognises two signing techniques. Docsliy applies whichever the transaction calls for — you don't have to work out which.

eSign

Aadhaar eSign

Online authentication through a licensed Certifying Authority, using an Aadhaar OTP or biometric.

  • Signs in minutes, nothing to install
  • Legal weight of a handwritten signature under Schedule II
  • Best for vendor, employment, NDA and lease agreements
DSC

Digital Signature Certificate

A PKI certificate issued on secure hardware by a licensed Certifying Authority — for counterparties without Aadhaar, or filings that require one.

  • Required for MCA, GST, income-tax and tender filings
  • Key pair held on a token, not in the browser
  • Class 3 certificates supported end to end

For counterparties outside India, identity is verified through Docsliy Verify instead. The signature routes correctly either way, without you setting anything up per signer.

Evidence and data

What gets kept, and what never does

Two short lists: what stays with the document as evidence, and what never reaches our systems at all.

01

An evidence-ready trail

Timestamp, IP, device and authentication method are retained with the document, supporting the presumptions in Sections 85B and 65B of the Evidence Act.

Why it matters: it puts the burden on whoever disputes the signature.
02

We never store the Aadhaar number

Authentication is performed by the licensed Certifying Authority, not by us. Aadhaar data is not used for any purpose beyond executing that signature.

Where it's written: our privacy policy states this directly.
03

The document stays with you

Where a licensed provider must apply the signature, we send only a SHA-256 hash — never the contract, its contents or its metadata.

How you check it: a hash is one-way and can't reconstruct the file.
What it can't sign

Some instruments are excluded, and we refuse them rather than produce something that fails.

The IT Act excludes a defined set of documents from electronic execution. Docsliy flags these at the drafting step so you don't discover it at signature.

Send one to a counterparty who has never used us

No account for them to create, nothing to install. If the instrument turns out to be one the IT Act excludes, you'll find out before you send it.
