Aadhaar eSign API for Rental Platforms and Property Managers
Rental platforms, co-living operators and property managers close dozens of agreements a month, and the landlord is rarely in the same city as the tenant. The SignYu API lets your platform send the agreement PDF to both parties for Aadhaar OTP eSign and pick up the signed copy by webhook. Pricing is from ₹15 per signature (₹15 per signature on packs of 10 or more), with API access at ₹999/month with a 3-day free trial. eSign handles the signing; stamp duty and, where required, registration are still your responsibility.
The problem with paper signing
- Landlords are often NRIs or live in another city, so collecting both signatures takes days.
- Move-in dates slip while the agreement is couriered back and forth.
- Co-living operators sign hundreds of short agreements and need a status per bed, not per spreadsheet row.
- Police verification and society NOCs are separate paperwork that also needs signatures.
Documents you can sign with the API
Rent agreement (11 months)
The common residential format. Pay stamp duty through the state's e-stamping system first, attach the e-stamp to the PDF, then send for eSign.
Leave and license agreement
Used in Maharashtra and elsewhere. In Maharashtra these agreements must be registered, which is done through the state's e-registration process; eSign does not replace that step.
Tenant police verification form
Landlord and tenant details for the local police. The form still has to be submitted to the police through their own portal or station.
Landlord NOC
Lets a tenant use the address for a GST registration, utility connection or company address.
How the integration works
- 1
Draft from booking data
Your platform fills the agreement template with rent, deposit, term and the e-stamp certificate number, and renders a PDF.
- 2
Create the document
POST /api/v1/documents with the PDF and a name like the property and unit code.
- 3
Add tenant and landlord
POST /api/v1/documents/{id}/signers. Put the tenant first if you want the landlord to countersign only after the tenant commits.
- 4
Send
POST /api/v1/documents/{id}/send emails both parties and returns signUrl values you can show in the tenant and owner apps.
- 5
Handover
On document.completed, download the signed PDF from GET /api/v1/documents/{id}, share it with both sides, and unlock move-in or key handover.
Legal validity
Aadhaar eSign through SignYu is issued via eMudhra and is valid under Section 3A of the Information Technology Act, 2000. The First Schedule of the IT Act excludes some documents from electronic signing: negotiable instruments other than cheques (such as promissory notes and bills of exchange), powers of attorney, trusts, wills and other testamentary dispositions, and any contract for sale or conveyance of immovable property or any interest in such property. A lease is a transfer of an interest in immovable property, and whether short residential rent agreements fall inside that exclusion is not settled. In practice many platforms execute 11-month rent and leave and license agreements with eSign after paying stamp duty, but take legal advice for your states and formats. eSign never removes the need to pay stamp duty, and it does not make registration unnecessary: leases of a year or more must be registered under the Registration Act, and Maharashtra requires registration of leave and license agreements regardless of term.

Frequently asked questions
Does eSigning a rent agreement remove the need for registration?
No. Registration depends on the term and the state. Leases of one year or more need registration, and Maharashtra requires leave and license agreements to be registered. eSign only covers how the parties sign.
How is stamp duty handled?
Pay it before signing, usually through SHCIL e-stamping or the state's own portal, and include the e-stamp certificate in the PDF you upload. SignYu does not collect stamp duty.
Can an NRI landlord sign?
Only if they hold an Aadhaar with an active Indian mobile number linked to it, because the OTP goes to that number. Otherwise they need another signing route.
Can a broker or property manager sign as a witness?
Yes. Add them as another signer after the tenant and landlord. A document can have up to 6 signers, and each uses one credit.
