Every document in a land transaction describes the property by survey number. The deed, the revenue record, the Encumbrance Certificate, the conversion order, the tax receipt.
If that number does not correspond to the ground you walked, every one of those documents describes something else. And the failure is quiet -- nothing in the paperwork looks wrong.
How survey numbers work
A survey number identifies a parcel as recorded in the cadastral survey. Where a parcel has been divided, sub-divisions carry hissa numbers: 42/1, 42/2, 42/3. Further division produces deeper numbering -- 42/2A, 42/2B.
Two properties that matter:
Survey numbers subdivide over time. A parcel sold as Sy. No. 42 twenty years ago may now be six separate hissas with six owners. A deed referring to the undivided number may not describe what is being sold today.
Survey numbers get renumbered. State re-survey operations, village boundary revisions and municipal mergers all cause renumbering. Land that was 47/2 becomes 112. Older documents in the chain of title will use the old number, and searches under the new one will not find them.
The documents that fix the parcel on the ground
The tippan (called a pot hissa tippan for sub-divisions, with different names across states) is the surveyor's sketch. It shows the parcel's shape, its measured dimensions, and its relationship to adjoining survey numbers. It is the document that converts a number into a location.
Obtain it from the survey or land records department for the exact hissa being sold. Then compare it against what you saw on site -- shape, approximate dimensions, and which survey numbers lie on each side.
The akarband or equivalent records the extent and assessment for the survey number and is useful corroboration on area.
The village map shows the parcel in context. Useful for confirming access, the relationship to roads and tanks, and whether the parcel is landlocked.
The correlation or re-survey statement maps old numbers to new ones where a re-survey has occurred. Ask for this specifically if any document in the chain uses a different number from the current one. Without it you cannot follow the chain across the renaming, and you will need to pull an Encumbrance Certificate under both numbers.
The checks to run
Confirm the exact string is identical everywhere. Survey number and hissa, on the deed, the RTC, the EC, the tippan, the tax receipt and the conversion order if there is one. Not similar -- identical. A deed for 42/2 and an RTC for 42/2A are different parcels.
Confirm the extent agrees. Compare the area on the tippan, the revenue record and the deed. Small variations in older records are normal. A gap of more than a few percent, or any gap you cannot explain, gets resolved before money moves.
Confirm the adjoining survey numbers. The tippan names what lies on each side. Standing on the plot, confirm those neighbours are where the sketch says. This single check catches the situation where a seller shows you a good parcel and sells you the adjacent poor one -- which happens, and is very hard to unwind afterwards.
Confirm the boundaries described in the deed. Deeds recite boundaries by direction: north by Sy. No. X, south by the road, and so on. Walk these.
When to order a fresh survey
Pay for an official measurement where any of the following apply:
- The extent on the documents disagrees with itself
- Boundary stones are missing, disturbed or disputed
- The parcel is a sub-division created recently or informally
- A neighbour disputes the line, or you saw signs of encroachment on the site visit
- The parcel abuts common land, a tank bund, a canal or forest boundary
- You are paying a significant sum per unit area, where a small error is real money
Most states have a process for applying to the survey department for measurement and boundary fixing, with notice to adjoining holders and a surveyor attending on site. It is slower than hiring a private surveyor but it carries official weight, and a privately drawn sketch does not bind your neighbour.
Attend the survey. So should the seller and, ideally, the adjoining holders. A measurement conducted with neighbours present and unobjecting is worth far more later than one conducted quietly.
Geo-referenced boundaries
Several states now publish digitised cadastral maps with geo-referenced parcel boundaries, and some listing platforms provide KML or GeoJSON boundary files for individual plots.
These are genuinely useful for confirming that the parcel you are being shown sits where the records place it, and for checking it against satellite imagery before you travel. Treat them as a strong cross-check rather than as the last word -- digitisation errors exist, and the tippan plus an official measurement remains the authoritative position.
After verification
Once the parcel is fixed, the rest of the documentation follows: the RTC, the Encumbrance Certificate under every applicable number, the chain of title, then stamp duty and registration and mutation.
