Start with Know the SRO where you can register — no account needed
Scroll to the panel headed Know the SRO where you can register and work down its four dropdowns: DISTRICT, TALUKA, HOBLI/TOWN and INDEX II: VILLAGE.
This is a public tool on the portal, and it is easy to walk past. It answers the question every other step depends on: which sub-registrar office holds, or can hold, the records for a given village.
Worked on our own two projects: choosing Bangalore Urban, then Anekal, then the hobli entry Sarjapura3, gets you a village list containing Sompura, which is where THE1 is registered. Choosing Sarjapura1 instead gets you a different village list, containing Sarjapura, which is where Saffron is registered. The same hobli name is split across three entries in this index, and our two projects are in two different ones.
What it is called on the portal
- DISTRICT
- TALUKA
- HOBLI/TOWN
- INDEX II: VILLAGE
What this step does not prove
The answer is a list of offices, not one office. For both of our villages the tool returned eight, under the headings Sl No., SRO and Address. Read the panel's own title literally: it tells you where a document CAN be registered, not where a particular document WAS.
