Chennai TSLR
The TSLR Extract, and Why City Flats Need It
Urban Chennai land is recorded in a different survey system than rural patta land — and the TSLR is the record that proves it.

What the TSLR is
The Town Survey Land Register is the survey record for urban land in Tamil Nadu. Cities were surveyed separately from rural areas, so land inside Chennai's town survey limits is identified by a town survey number and recorded in the TSLR rather than in the rural patta system. For a city flat or an urban plot, the TSLR extract is the document that ties your specific parcel to the official survey — which is why buyers and their lawyers increasingly ask for it directly, not just for a patta that may not even apply to urban land.
Why it catches people out
Many buyers arrive knowing to ask for 'patta' because that's the word they've heard, and are surprised when a city flat's paperwork runs through the town survey instead. A missing or mismatched TSLR extract — where the survey number on the document doesn't match the records — is exactly the kind of gap that's cheap to catch before an advance and expensive after. This is not for you to skip if you're buying an urban flat: the extract is how you confirm the land under your building is what the seller says it is.
Where it fits in the checklist
FIFSCORE™ places the TSLR alongside the EC and the parent documents so the urban-land question is answered, not assumed. The extract is obtained from the survey and settlement records — often via the same revenue channels and online services that handle land records — and a clean one shows your parcel's town survey number consistently across documents. Read as part of the set, it closes the specific risk that a city property's land identity is unclear; skipped, it leaves a blind spot no EC will cover for you. For an urban flat it is one of the few records that ties your building's land directly to the official survey, which is exactly why a careful buyer asks for it by name.

What is a TSLR extract and do I need one?
The TSLR (Town Survey Land Register) extract is the survey record for urban land in Tamil Nadu. If you're buying a city flat or urban plot in Chennai, it's usually the key survey document — more relevant than a rural-style patta — so yes, you generally need it.
How is TSLR different from patta?
Patta is the rural revenue record of landholding; the TSLR records urban land surveyed under the town survey system. City properties fall under the town survey, so the TSLR extract, not the patta, is typically what proves the land identity of a Chennai flat.
