Every registered transaction recorded against a property at the sub-registrar office.

Status: LIVE. Source status: No recent runs. Typical time: up to 10 min. state: `telangana`, search_type: `ec`.

Uses an OTP: LegiScore handles the code; the search may show awaiting_otp briefly. AI Recovery does not run on this search.

## What you get

Transaction rows plus the official EC statement PDF.

## Request parameters

Keys of `params`. A value "from lookup" is a code you get by searching for the item by name first (https://legiscore.in/docs/api/lookups).

- Both together `doc_no`, `year`: Give both the document number and its year of registration.
