Tamil Nadu Property Checks: Guideline Value, Patta Chitta, and TSLR Explained
Buying property in Chennai, Coimbatore, or Madurai comes down to three questions. Is the price fair? Does the seller actually own the land? Is it already mortgaged to a bank? Tamil Nadu answers each of these through a different government record, and each record lives on a different portal. Mix them up and you can overpay on stamp duty, buy from someone who only thinks they own the plot, or inherit a loan that was never cleared.
This guide maps each question to the right record. We have run thousands of these checks for buyers and NRIs, and the same confusion shows up every time: people pull a patta and assume the title is clean, or they check a guideline value and assume that is the market price. Neither assumption holds. Here is what each record proves and where it falls short.
Is the price fair? Start with the guideline value
Guideline value is the minimum value the Tamil Nadu government assigns to a property for the purpose of calculating stamp duty and registration charges. It is Tamil Nadu's term for what other states call circle rate, ready reckoner rate, or collector rate. You cannot register a sale below this figure, and the registrar uses it as the floor for duty calculation.
The guideline value is set street by street, and in some areas survey number by survey number. A road in T. Nagar will carry a far higher guideline value than a comparable plot two kilometres away, because the rate reflects location, road access, and land classification rather than the price you negotiated. The state last revised guideline values on 1 July 2024, so any figure quoted from before that date is stale.
How do I check guideline value in Tamil Nadu?
Go to the official registration portal at tnreginet.gov.in and click "Guideline Value" on the homepage. You can search two ways: by street name within a registration zone, sub-registrar office, and village, or by survey number for areas where the value is fixed at the survey level. The portal returns the per-unit guideline value for that location, which you multiply by the built-up area or land extent to get the chargeable value.
For an apartment, the guideline value applies to the undivided share of land plus a separate composite rate for the construction. For raw land, it applies to the extent in square feet or cents. The figure you get is what the registrar will use, not what the seller is asking. This matters because the gap between the two drives your stamp duty bill and can trigger a valuation dispute. Always pull the guideline value yourself rather than trusting the seller's number, since an understated value at registration is the most common reason a document gets referred for re-valuation later.
Guideline value versus market value, and the Section 47A trap
These two numbers are rarely the same. In most Chennai micro-markets the negotiated market price sits above the guideline value; in a few slow pockets it can fall below. The law cares about both. Stamp duty is charged on whichever is higher, the consideration stated in the deed or the guideline value.
Here is where buyers get caught. Under Section 47A of the Indian Stamp Act, 1899, as applied in Tamil Nadu, if the registering officer believes the market value has been understated in the document, the officer can refer the instrument to the Collector for a valuation enquiry. The Collector determines the true market value and the deficient duty. If undervaluation is found, the deficient duty carries interest at 12% per annum from the date of registration, and an intentional understatement attracts additional penal interest at 3% per annum. The reference can be made within three years of registration, so the risk does not end the day you register.
The lesson is not to register at exactly the guideline value when the real price is higher. Doing so saves duty today and invites a Section 47A notice tomorrow, with interest stacked on top. Madras High Court has also held that the market-value power should not be used routinely to reopen documents without concrete evidence of understatement, which gives genuine buyers some protection, but the cleanest path is to register at the actual consideration.
What stamp duty will I actually pay?
Tamil Nadu charges 7% stamp duty and 4% registration fee on a property sale, a combined 11% of the chargeable value. On a 1 crore flat where the guideline value supports that figure, that is roughly 11 lakh in government charges before you account for the price itself. From 1 April 2026, women buyers of property valued below 10 lakh get a 1% relaxation on the registration fee, paying 3% instead of 4%. Confirm the current rate on tnreginet.gov.in before you budget, since the registration department revises fees and concessions periodically. For a state-by-state comparison of how these charges stack up, see our stamp duty and registration charges guide.
Does the seller own it? Patta, chitta, adangal, and TSLR
A guideline value tells you the floor price. It tells you nothing about ownership. For that you need the revenue records, and Tamil Nadu has several, each describing a different slice of the same plot.
Patta is the record of ownership for a parcel of land, issued by the revenue department and naming the person in whose name the land is recorded. It lists the patta number, survey and subdivision numbers, the extent, and the tax assessment. When someone says "the land is in my name," the patta is the document they are pointing at.
Chitta was historically a separate record describing the land's classification, mainly whether it is wetland (nanjai) or dryland (punjai). Since 2015 the Tamil Nadu government merged patta and chitta into a single combined record, so you now request "Patta Chitta" as one document rather than two. If a seller hands you an old standalone chitta, that is a sign the records have not been refreshed.
Adangal, also called the A-register extract, is the village account that records crop and land-use details against each survey number over time. It is most relevant for agricultural land, where it shows what the land has been used for and helps confirm the classification matches what the seller claims.
Why a city property needs a TSLR, not just a patta
Here is the distinction that trips up most urban buyers. Patta and adangal are village-level revenue records built for rural and agricultural land. For land inside a surveyed town or city, the controlling record is the Town Survey Land Register, the TSLR.
TSLR extract is the urban land record maintained for properties inside town survey limits, showing the town survey number, sub-division, ward, block, boundaries, classification, and land use. If you are buying a flat or plot in a notified urban area of Chennai, Coimbatore, or Madurai, the TSLR is the record that authoritatively describes your parcel, because urban land is surveyed under a separate town survey rather than the village survey that produces patta numbers.
A patta may still exist for urban land, but it does not carry the town survey detail a registrar and a bank rely on. Pulling only a patta for a city apartment and skipping the TSLR is one of the most common gaps we see. The two records use different numbering systems, and an honest seller will be able to produce both. If the survey number on the patta cannot be reconciled with the TSLR ward and block, stop and investigate before you pay anything.
Where do I get patta, chitta, and TSLR online?
All three come from the same place: the Tamil Nadu e-Services land records portal at eservices.tn.gov.in. The site is bilingual, in Tamil and English. From the home page you select the record you want, View Patta and FMB, Chitta, or TSLR Extract, then choose the district, pick rural or urban, and enter the taluk, village, and survey or patta number.
For a TSLR extract you supply the village or town, ward number, block number, survey number, and subdivision number, then verify your mobile number by OTP to view or download the extract. For rural and natham (village residential) land you can also pull the FMB (Field Measurement Book) sketch, which shows the plotted boundaries. Natham land is village house-site land and is handled through a different service path than urban TSLR, so make sure you are pulling the record that matches the land's actual classification rather than assuming one form fits every plot.
Is it mortgaged? Pull the encumbrance certificate
Ownership records do not show loans. A patta will happily name an owner whose property is mortgaged to a bank for 80 lakh. To see registered loans, sales, gifts, and other charges, you need the encumbrance certificate.
An encumbrance certificate is a record of all transactions registered against a property over a stated period, showing sales, mortgages, gifts, and releases, or confirming the property is free of registered encumbrances. It is the document that tells you whether the title has moved and whether money is owed against it.
You pull the EC from the same registration portal as the guideline value, tnreginet.gov.in, under E-Services then Encumbrance Certificate then View EC. You can search by EC, by document number, or plot and flat-wise. The portal covers up to 30 years of records, online viewing is free, and a certified copy carries a small fee. We cover the full procedure in our Tamil Nadu encumbrance certificate guide, and how to actually read the entries in how to read an encumbrance certificate.
Pull at least 13 years, and 30 if the portal will give it to you, so you capture the full chain of past owners and any old mortgage that was never formally released. An entry showing a mortgage with no matching release deed means the loan is, on paper, still live.

What these records do not show
Running all five records is the baseline, not the finish line. Government records have blind spots, and the gaps are exactly where disputes hide.
An encumbrance certificate only shows registered transactions. An unregistered sale agreement, a power of attorney handed to a third party, or an oral family arrangement will not appear in it. A patta confirms who the revenue department records as owner, not whether that record is being challenged. A pending civil suit over the title, a partition dispute among heirs, or a stay order from a court does not surface in any of these portals. We have seen clean ECs and valid pattas on properties that were under active litigation, because litigation lives in court records, not revenue records.
Records also lag reality. A patta may not yet reflect a recent inheritance, and a guideline value revision can change your duty between the day you check and the day you register. Tax dues to the local body, unapproved construction, and building-plan deviations sit outside this set entirely. A complete title check cross-references the revenue records against the registration records, the court records, and the encumbrance trail, and reads them as one story rather than five separate downloads.

Doing all of this without 15 browser tabs
Pulling these records by hand means hopping between two state portals, solving captchas, entering survey numbers in slightly different formats on each site, and then reconciling records that use different numbering systems. For an NRI in Dallas trying to vet a Coimbatore plot across a 10-and-a-half-hour time difference, it is worse, since the portals can be slow and occasionally down.
This is the problem we built LegiScore to remove. It runs across 15+ government portals, including TNREGINET for guideline value and EC and the e-Services land records for patta, chitta, adangal, and TSLR, pulls the records, cross-checks them against each other, and returns a structured legal opinion in under 15 minutes at 199 rupees per title search. You enter the survey or document details once instead of fifteen times, and you get a single read on whether the title holds rather than five disconnected PDFs to interpret yourself.
The records themselves are public and free to view. What takes the time, and what causes the costly mistakes, is gathering them, reading them together, and spotting the gap between the patta and the TSLR or the mortgage with no release. If you would rather not assemble that picture by hand, LegiScore does it for you. If you prefer the manual route, the portals above are the right starting points, and the related guides below walk through each one.
Frequently asked questions
Is guideline value the same as market value in Tamil Nadu? No. Guideline value is the government's minimum value for calculating stamp duty, set street by street and last revised on 1 July 2024. Market value is the price you actually negotiate, which is usually higher. Stamp duty is charged on whichever is higher.
Do I still need a separate chitta document? No. Tamil Nadu merged patta and chitta into a single combined record in 2015. You now request "Patta Chitta" as one document from eservices.tn.gov.in. A seller producing an old standalone chitta is a sign the records have not been updated.
Why do I need a TSLR if I already have the patta? Patta is built around the village survey and is the standard record for rural and most land. Urban property inside town survey limits is governed by the Town Survey Land Register, which carries the town survey number, ward, and block that a registrar and bank rely on. For a city flat or plot you need the TSLR, not just the patta.
Does an encumbrance certificate show court cases or disputes? No. An EC only shows registered transactions such as sales, mortgages, gifts, and releases under the Registration Act, 1908. Pending litigation, partition disputes, unregistered agreements, and stay orders do not appear in it and must be checked through court and other records.
Can I check all these records from outside India? Yes. Both tnreginet.gov.in and eservices.tn.gov.in are publicly accessible online, though they can be slow and need OTP verification on an Indian mobile for some downloads. NRIs commonly use an automated service like LegiScore to pull and reconcile every record in one pass instead of fighting the portals across time zones.
