PilotL4: land listings a lawyer has checked first
L4 is our land marketplace. Before a listing goes public, a lawyer checks its documents, traces the ownership chain and issues a certificate with a risk score — and an admin clears every buyer enquiry.

The brief
Buying land shouldn't start with a gamble
Land buyers often learn about a title problem only after they have paid an advance. Sellers, meanwhile, take calls from people who were never serious.
L4 puts a lawyer's check before the listing, and an admin between buyer and seller.
What we delivered
- Web marketplace and mobile app for buyers and sellers
- Lawyer workspace for document review and certificates
- Admin approvals on every enquiry, sharing only the seller details picked

What L4 does
Browse
Only listings a lawyer has checked
Buyers browse land that has already been through a lawyer's review, with each listing's risk label and price per acre up front.

Verification
Seven stages from upload to publish
The team moves each listing through seven verification stages — assigning a lawyer, tracking which documents are verified, and publishing only once the legal opinion is in.


Certificate
An ownership chain and a risk score
The lawyer rebuilds the chain of past owners from the documents and issues a legal opinion with a risk score — and buyers can download the certificate.

Languages
In English and Tamil
Every screen is available in Tamil, so buyers and sellers can use L4 in the language they read best.


Admin
An admin between buyer and seller
Every buyer enquiry waits for an admin. When they approve it, they pick exactly which seller details the buyer gets — so sellers only hear from serious buyers.
